Tensei Shitara Slime Datta

Chapter 215: The Closed World

I sighed, as I looked at Diablo, who was going to "Kufufufufu".

He really got carried away. It was like he said, 'Thank you so much!' .

Big piercer who is Diablo ―― opponent I think Footman is his name ―― I can't help but feel sorry for him.

He's crazy enough now, only to have the motive to kill all the moving objects around him, but it's not like I'm really worried about him.

The person I need to worry about, is Leon who is now fainting in front of me.

I walked over to Leon's side, and placed my hand on his chest.

Leon's subordinate looked at me all surprised, but I put a finger on my lips, as a sign to keep them quiet.

Now is not the time for vocal strife.

I took out the Full Potion from my chest pocket (which is actually 『Imaginary Space』), and I used it to seal the gaping hole in Leon's chest.

But, the potion only did that much. Leon hasn't woken up, even though his body has been repaired.

But, there's no need to panic.

This is still, the world is enclosed within the barrier of Mizari.

You could say, that Leon was really lucky. Just because, if I don't come he'll be in real danger.

First of all, if I give a reason why we are here――

I let Velda assume that I was dead, as I observed everything that was happening in the world while hiding in the shadows.

The mini clones of Moss that Diablo secretly disbanded, were very convenient. They provide some of the best spy information, as always.

Magic my observations, and intelligence spy Moss.

Understanding what happened anywhere was easy, no matter where I chose to hide.

Well, transferring the information to an alternate dimension that I was hiding required some work, but I asked Ciel to do this so that this problem was solved.

Using some magic theory that I did not understand at all, he created a comfortable space for where we did our spying activities.

As expected of Sensei. He is as powerful as ever.

We collected all sorts of information in that space, and when I saw it all with Diablo. . .

Velda's presence was detected, in Leon's territory.

《There is a very high possibility, that it is not its main body. But, the chance to get much needed intel is also there—》

I saw .

If those were sensei's words, it would be true.

And that, is the crux of why I am here now.

Well, this is not like the situation in other locations can be ignored, but this war ended when Velda was defeated, so what I will prioritize is quite clear.

In Guy's place, his battle with Chloe is escalating but there hasn't been a major change.

The Ruminas side are also in an emergency, but there are Adalman and Albert, along with Shion as well. They'll hold on for a while.

It would be best if I could defeat Velda when he appeared here, but it was just wishful thinking.

It seemed like Velda's goal, was to recover the strength he had given Kazaream.

He gives the physical mass a projection, which means he connects a portion of his actual body as part of the projection data with an ability similar to 『Parallel』 Existence.

Parallel existence, is an ability that allows the user to control clones of himself, but requires Energy to be shared for each copy.

What he did, was that he simply overlapped his consciousness with the projection data so as to allow him to recover power as data, which sounded correct.

『The ever-present existence of Parallel』 'main body', or 『Double』 existence where each copy is 'main body'.

Which is harder to handle, depends on the person using that ability.

However, in terms of capability classification, 『Double』 existence is definitely one of the highest level abilities without a doubt.

Even now, as Ciel-sensei analyzes it now, I can say that with confidence.

But I digress.

The moment I arrived, just when the copy of 『Ganda』 Velda's existence had finished recovering the power from Kazaream.

I just missed him.

There's nothing I can do about that. By the time I teleported after detecting her, Velda had already finished what she came here for.

Information is conveyed at the moment of cognition. It was one of the annoying things about 『Ganda『 existence.

It is impossible to beat the transfer speed, unless you use some ability to stop time.

According to Ciel-sensei, the speed of data transfer is practically faster than the speed of light.

It was word for word, "at the same time".

So, there was nothing we could do to prevent Velda from escaping our fingers this time.

After all, this is just a part of him as data so it's not like we can give him the final blow, so I won't lose sleep because of this.

The real problem happened after that.

Mizari fixes a hole in the barrier that the battle of Benimaru and Kazaream opened.

It might be an attempt to cut through Velda's data body, but it was impossible even with the speed of the demon's reaction.

Instead, you could say it was a daring effort, with the situation being like that.

Me and Diablo snuck in through the hole too, but now we're stuck inside too.

For those of us who painstakingly avoided being discovered by Velda, breaking the barrier to leave was no way. We'd be caught if we did that.

This was a rather embarrassing situation, so Diablo and I completely hid our presence and observed the others instead.

So, we sat down for a while, and Leon fainted soon after.

Looks like it'll be a "confirmed death!" if this continues, then I decide to lend a hand and make my appearance.

It was after getting the green light from Ciel, after confirming no data could be transferred in or out of Mizari's beautiful barrier.

If, there was any chance at all that I would be found by Velda, I would leave Leon to his own fate.

Don't think too badly of me, the important thing now is to defeat Velda. It may look cold but this is just me setting my priorities.

But, this is good luck for Leon, as our current location is completely sealed off from the outside world.

I immediately strengthened the barrier of Mizari, in preparation to make my appearance.

――And here we are again, when I started taking care of Leon.

At a glance, his soul seemed to be intact, but his Core had been damaged.

It was a source of strength, achieved by an awakened hero. If this is broken, they become unable to control their power properly.

That was what was reported, after Ciel sensei carried out the analysis calmly.

Fumu fumu, what should I do now.

But, the rest made a fuss which was a problem.

Benimaru seemed to be severely depleted after his fight with Kazaream, and could not defeat the blob in a single strike like now.

As expected he understood that he should not waste energy in attacks that did not get results, so there was no sign of him trying to do such things.

Souei and that Laplace Devil as well, lacked the firepower to cause decisive damage.

Mizari put all her efforts into the barrier, which was the right decision.

They seemed to be stalling until Benimaru recovered his energy, but that would not give me much composure to continue treatment.

I felt a bit bad for Benimaru, but I judged that it was time for Diablo to perform.

"Good! Can't help it huh. Do it for it, Diablo-san! 」

The moment I gave my order, Diablo who was standing at the side acted.

「Kufufufufu. Leave it to me, my lord! 」

He happily and magnificently made his appearance, grabbed the butler and slammed him to the ground.

That was the beginning, was my thought when I saw what was happening.

The rest were shocked, and Diablo with an arrogant face.

From there, the situation is expected to be one-sided.

I focus on taking care of Leon, and when I peek at what happened—

「Kufufufufu. What's wrong? Is that all that is your strength? All

It turned into a situation where I wanted to say, "What kind of criminal are you!" .

Well, is it because I also gave him an order with a somewhat evil tone? Well, that's an* maybe not.

Diablo cut the Footman's dice with claws on both his hands, showing the difference in strength between them. Naturally, the parts that were cut were slowly reduced.

Diablo cut him off at a speed that beat his regeneration.

Huge flashes of light and collisions occurred occasionally, would the barrier survive like this?

I was worried, even though I was strengthening the barrier.

(Hey, hey, is this gonna be okay? Did Diablo forget that we should try to get away from Velda's radar?)

《Valued is under control. At that point, Diablo had a closed headquarters. 》

Ciel confidently replied.

Oh I see it now, I do not pay attention to when, but Diablo has used 『His Temptation Azazel』 and activated 『Goddess Dunia』.

As expected of Diablo, his fighting style was as shrewd as ever.

Diablo won't make the same mistake that Benimaru did, huh.

(Hmm, looks like it won't be a problem. Don't think I need to worry, and leave it to Diablo ..)

"That'll be fine . Looks like he will not fail to unleash the Ultimate Skill 『The Evil Dragon Lord Azi Dahaka』. 》

Eh !?

You mean that part !? I'm not worried about that !!

Without me realizing it again, the main prerequisite became stealing the enemy's abilities.

I'll just let you guys do that.

I have gone beyond shock, and only half-heartedly returned to do Leon's treatment.

As I continued with Leon's treatment, I heard Benimaru and co.

「. . .you know, I've been thinking. . . But the devil, isn't he just nonsense?

How is he ―― he just rudely forced his way, but how does he not show any signs of exhaustion? 」

「Ahh, correct. He's just that kind of person. . . 」

「As expected of Diablo-sama. . . It seems like I, still have a long way to go. 」

「Do not consider it as standard. That's not a battle style we can learn, that's why he only dared to show his hand.

Suicide even thought to try what he did. 」

To Laplace's question, Benimaru threw a reply.

Mizari only gave honest feedback to her, while Souei calmly analyzed and gave a warning.

I don't think there is a need to explain in detail to someone who is only a temporary ally, but maybe Souei is a little shaken from the situation.

After all it wasn't easy to replicate, so he probably didn't care much.

He was shocked enough by the terrifying spectacle to lose all words for a while, but it seemed like he had calmed down enough already.

From the previous emergency, the situation might feel like a joke to him right now.

Accepting the fact that just happened must have troubled him.

「Kufufufufu. Oh, forgive me. It seems like I pushed myself too hard, it seems like I tore his arm off. 」

His enemy curled up as if trampled by a powerful one, as the demon chuckled.

This was all too one-sided to call it a fight, even the spectators felt uneasy when they were watching.

Diablo was so overpowered, it seemed like he was playing around.

But, contrary to his tone, Diablo made use of an extremely high level skill and continued his battle recklessly.

Destroying the parts as he continued, he slowly sucked up the Footman's energy.

The claw whose hand was wrapped, was the Energy of Turn Null 』 in a highly compressed form.

He used the Energy he borrowed from me with a focused style. Such a feat was only possible, with his overwhelming sense of battle.

First, from what can be concluded by looking at the remnants of the ―― battlefield of course Ciel sensei who did that――, the Energy that Benimaru borrowed from me, he released it all in one instant.

Controlling this vile void energy and throwing it at the enemy, this of course works against most creatures.

Most of it would probably be destroyed without being able to resist.

But there is always a price to pay.

You have to use most of your own Energy, and become unable to continue with the prolonged battle like how Benimaru is now.

It is great to keep as an ace in the hole, but it is not something that can be used carelessly.

At that point, Diablo's method of using it was more reliable.

Special training to kill time in the past two days, certainly paid off.

It was the Energy circulation method thought of by Ciel sensei, while we hid in the subspace.

Exactly named, "Torus Secret Art".

It was just an incredible name for it, but basically, it only used the ability of any type of space control to create a situation to prevent the energy from spreading, then reabsorbing the used energy.

Citing the example, when Diablo was in the "World of Experiments", he could recycle his own energy constantly.

This logic was difficult to understand as magic, but Diablo was able to understand Ciel's words.

Say, there is your energy and the energy of other beings, in a closed world.

Your goal is to neutralize the opposition of ―― or, mutual dispersion is also fine but, but actually, the idea is to separate one energy and release the other from that closed world.

Then, you reabsorb whatever energy is your energy.

The energy released by the opposition is then used to sustain the 'world' created for this purpose.

By using this cycle, it becomes possible to one side weaken your opponent.

To be honest, I couldn't understand those things, but Diablo managed to do it.

Even now, the audience might think that he was violently forcing his way, but the truth was far from that.

Looking at their reactions, the few who really understood what was going on, were probably only Benimaru and Mizari.

Well, saying that they understand feels like a stretch. More than that, they do not fully understand the inner workings, but can say that something is happening.

It might be a good idea to teach Benimaru about this afterwards, but would he be able to understand this?

I have Ciel with me, so there is no problem even if*I*do not understand this.

Mm, the only support I can give her is to get around that with fighting spirit or something.

As expected even if this was a closed world (in a barrier), it was not really able to withstand the explosion of a single-powered void energy, so it required some adjustments.

If you ask who can do this after hearing his theory, Diablo is most likely the only one capable of doing so.

As I watched the Diablo battle in the distance, Leon's injuries were completely healed without me noticing.

In the middle of it, I threw all the work into Ciel!

That's my motivation.

If he was a bishoujo, things would obviously be different, I don't really care about men, let alone an Ikemen.

Honestly, "motivate, drop!" .

Because that's in the middle of it,

(I'll hand it over to you!)

So, I let Ciel do all the work without any intention of listening to all the explanations.

It was mostly down to one ear and out the other, but I think it was some thing about his Hero Core being broken, so a replacement was needed.

Reawakening him normally would cause a decrease in his combat ability, so I chose to heal Leon without causing it to happen.

What's with all the permission he asked of me.

So I diverted all of that with "Ciel sensei who was always careful!"

But, when I saw the revived Leon, I was half suspicious of my own eyes.

Huh huh? It's not like, he's too strong. . . I almost shouted, "C-Ciel sensei, what are you doing !!" .

An analysis showed, that he had become a Demi God.

Before this Leon had a large amount of holy aura within him, now he had become an extremely holy aura that used to exist within him.

Simply put, it has become a spiritual entity.

He doesn't have a Core now, so to adjust the flow of Ki, he's remodeled to work without the need for cores.

I saw . . . Not that!

Even though he is not hostile towards us, why did you go and strengthen this person who is not an ally!

. . . . . . Well, I'm the one who diverted that information.

It makes no sense for me to complain now.

God, everything's fine if we don't hate him.

Moreover, the change was done forcefully, so it took him a while to be able to fully use his new strength.

So we just need to finish Velda, before it gets to that point.

Yeah, things will be fine. I won't let this bother me.

As I contemplated such things, Leon began to regain consciousness.

He opened his eyes a little, looked at me. And,

「Shizu, yes. . . Heh, have you come to take revenge on me? 」

Somehow, he seemed to be continuing with the half-asleep nonsense.

「If I am destroyed by you, then I will accept it. Now, do your worst. 」

Leon keeps babbling.

It seems, he mistook for Shizu-san.

That's very upsetting.

I see,

「Fwha-!」

I threw Leon, whom I carried. (TN: no homo)

Why should I care so much, for someone who has fully recovered.

「――! Is that you, Rimuru? 」

「Ahh, finally awake? You better thank me, worship me too! 」

「I. . . I see, so you're the one who turned on me―― 」

I twist my hair and nod.

I practice this secretly, a pose where I (should) look amazing.

「Thank you very much, Demon King Rimuru. 」

「Umu. Thank you very much! 」

She thanked me, I don't think I need to worry for now.

When Leon and I were doing our short play, Leon's followers were in unison,

「「 「Leon-sama !! Thank you, you're fine !!! 」」 」

So, they all came when they said that.

Some even cried, but no one was hurt.

I've done so much, I'll just add this as a bonus.

I take one Full Potion for each person, and crush it on each individual.

"Are you-!?"

The shocked said that, but then they saw their injuries disappear almost instantly.

This was even more effective than magic, unable to help they would be shocked.

Just when all their injuries were healed,

「「 「Satan Lord Rimuru-sama, the great help you have given us, will not be forgotten !!!」 」」

All of Leon's followers knelt down, and bowed their heads to me.

Mmm, this kind of thing doesn't mean much to me.

I feel a little embarrassed, so I hope they will stop with this formal thing.

Now that Leon has been revived, and with his followers making a big fuss over this, of course Benimaru and his partner. have noticed me as well.

「「 Rimuru-sama! 」」

Benimaru and Souei came closer.

「So you're really fine!」

「See, what did I say? There's nothing to worry about! 」

「Not that, what Zegion said. . . 」

「I won't have it. I believed it from the beginning! 」

As expected, they were a bit panicked when the news of my destruction reached them.

Zegion soon realized – he was completely unaffected – that my heavenly protection was not lost, which helped calm everyone.

「Uh, soup. You guys okay? I was thinking of making Velda lower his vigilance with this.

In addition, the plan was to finish off the rebels as well. 」

I try to smooth my way with this explanation.

But it turns out that this is more than enough.

「So that was the plan, yes. 」

「As expected of Rimuru-sama. Now, how do we (your followers) have to do this? 」

Benimaru looked confident, while Souei asked for details with the intention to take immediate action.

Now hold your horse.

There's still someone hitting the Footman, don't forget him.

With my appearance, you guys feel too relieved or too enthusiastic.

「Wait a minute, we should end the battle here first. Diablo, are you all okay in there? 」

After all I have been found by them, there is no need for me to order now.

I decided to defeat the Footman as soon as possible.

「Kufufufufu. The preparations are mostly done, Rimuru-sama. 」

"Good . 」

I nodded, and walked towards the Footman.

「Sky, sialnnnnnnn! Just what, what is going on !!

You insect! To do this, to me the great Footman-samaaaa !! 」

To the Footman who didn't even know what was left or now, Diablo gave one last strike to him.

「You're noisy, close your trap. 」

When he said that.

The footman becomes unable to speak, as his lower jaw is blown away.

Eww that looks unpleasant. I'll do this quickly.

「I won't make you suffer again. You will find peace within me. 」

And I devoured it, after saying that.

Since Diablo's work weakened him, the Footman's consumption was completed quite quickly.

It went so easily to the point where he didn't even have a chance for a final struggle.

And as Ciel planned, I also managed to obtain the Ultimate Skill 『The Evil Dragon Lord Azi ・ Dahaka』.

「Kufufufufu. As expected of Rimuru-sama, it was done really well! 」

「Oh no, this is all you Diablo, you help weaken it a lot. And also, good work there Benimaru and Souei. 」

"""yeah!"""

The three of them knelt down, and acknowledged my praise.

They do this every time it feels a bit uncomfortable to me, but formality is important to them.

So, the current threat disappeared very easily.

Later,

「This is hard to accept so suddenly, but seriously, what the fuck is. . .

Well, we can get rid of demons, but the Demon King is too unbelievable. . .

Anyone who would really fight with him, could only be a madman or completely insane.

It puts a nail in the coffin. I am now sure Kazaream-sama must have been brainwashed in some way. 」

"I think so too .

Kazaream-sama has always been careful, he has never been hostile towards such a monster.

He would even go out of his way to secretly push for an alliance in the shadows, which would definitely be plenty. 」

"I know? He was the sneaky type who would not think twice about these kinds of things. 」

The two of them completely let things go as if they had realized something important.

One of them, the Laplace Devil, was a dangerous person who was at least on par with Souei.

It might not be a good idea to let them.

If that's the case, then,

「So, you two are there. Let's work for me, kay! 」

I will only make decisions for them.

"Wait-wait! What you decide yourself―― 」

「Kufufufufu. Is there, * is there a * problem with it? 」

「Eh, ah. . . You know–"

Laplace seemed like he wanted to object, but was at a loss for words before Diablo's "smile.

He finally fiddled with his fingers.

I was rooting for the girl beside him (You can do it!), But he could only quietly say, "It's impossible for me ~".

It makes me feel a bit sorry for them.

「Err, well. . . You said you recruited us, so does that mean we can expect pay? 」

「Hoon, salary!」

"ah! No, that's not what I meant. . . 」

「Hooh? Then, mind if I ask what do you mean exactly? 」

「Errrr, that's uhh. . . 」

Salary, yes.

Come to think of it, back in Tempest it was mostly like a material reward system, we actually did not have a salary system.

I did want to think about it a while ago, but forgot about everything that happened. I need to discuss with Myourmiles about this.

「Hey, those small details can be discussed later. So, what's your choice? 」

「Understood! Then I'll be in uhh, your care! 」

「Ah, me too!」

Laplace and Tear, these two demons are now in my custody.

There are no salaries yet, so it seems like they are in danger of being hired, but you lose if you think too much about these kinds of things.

There is also Diablo who wins (threatens) them with his "smile.

After all that, we held a small conference, together with the revived Leon.

First, to keep them quiet about me because I'm hiding.

It's obvious, but the alliance will be cancelled when information about me is spread. It basically means I will let their country be destroyed if that happens.

This made most of them pale in the face and they nodded in agreement, no worries here for me.

Me and Diablo will go back into hiding after this, so it's important that we don't let Velda pay attention to anything.

As for Leon's country, they would still continue to fight with the troops led by Kazaream.

They should at least be able to manage this much. I went and fully healed all the key appointment holders, and the opposition leader has dealt with as well.

Benimaru will return to Tempest to lead our side again.

Souei will support Benimaru.

As for Laplace and Tear, I ordered them to stay in Leon's country and help with the defense. They will help strengthen the country they initially attacked ―― but the losses are not as big as previously estimated ―― as reinforcements.

It's not like there won't be any hatred left at all, but I order them to keep those things to a minimum.

I pushed the gratitude they had for me into Leon's face as well, to make him forgive them.

It was selfish of me to do this, but that's what I did.

I made them promise to work together, even if it was limited to this moment, but this is good enough for now.

What comes after, it can be decided when this great war has been won, and that we are saved.

Also, although I feel a bit bad for Leon and co. , this was also meant as a test for Laplace and co. . I don't want to split the Tempest troops any more than they already are, so this is a win-win condition for me.

I want them to work hard, and focus on the defence of the country.

Just in case, I asked Souei to keep an eye on them.

Whether I decide to fully trust Laplace and co. or not, will depend on Souei's report once everything is done.

At the very least, there would be no problem if they did not betray me during the great war.

There was also the thing about Velda brainwashing Kazaream – perhaps it was his – Thinking Guidelines that was angered by Laplace, so I don't think he will betray me at this point.

So our plan of action was more or less decided, although the approval of the others had mostly been forcibly refined by me.

And thus, the commotion in Leon's country, ended with an important event.
