Zen returns to the kingdom with Meta, Sekar, and Prince Albert. This expedition can be said to be successful with them getting Golden Eggs which then the object was handed over to Meta to do further research. For Zen and others, they return to their own daily lives.
Currently, Zen was in princess Sistina's room. Only the two of them there would talk to each other.
"You've become stronger, yes," said Princess Sistina, "With your immortality, you've become the strongest person in the world, haven't you?"
"No, it's still too soon to say myself as the strongest," Zen said, "There are still people out there who can beat me."
And recalling the time Four Symbols attacked him to the point of cornering him. From there he knew, it was still possible to seal or restrain him even if he was immortal. It would be a point of weakness for him as someone who held immortality. And again, the fact that Zen is bad at sealing magic, as well as being sealed he might not be able to escape and that would be the end for him.
Princess Sistina sighed. He himself knew that if the power of Zen, even without considering the Eternity of the Phoenix, the juvenile in front of him was still likely to destroy the capital alone. It was good to have powerful pawns and subordinates, but if it was too powerful, getting to the stage of not being able to control it, it would be a double-edged sword that would probably threaten the kingdom for the future.
And now, even though Zen had gained immortality that could temper most attacks, but he still wanted to become stronger. Now I've become a problem. More powerful and what can the kingdom do?
"Do you know how to become stronger?" ask Zen.
"You want to be as strong as what?" princess Sistina replied, "There are only three ways to become stronger: Practice, strengthen weapons, and gain experience. You just have to keep those three things and you'll be strong little by little."
"Hmm, that's right. I need to improve 'experience' to enrich 'knowledge'. And it seems, defeating monsters will not be enough. Did you think of a way to gain knowledge instantly?" Zen smiled gently.
Princess Sistina smiled dryly. Not answering.
"You're gonna take that as a 'no', and I need to figure it out myself." Zen lift foot. "Thank you for the time."

Zen took a walk inside the royal palace while thinking about what he would do next. Hunting and attacking the demon kingdom was indeed the goal they had been summoned from the beginning and he could do it right now, just because the war had not really started yet, the kingdom constantly trains heroes to strengthen their pawns. It would be better to have no stronger and definitely not be defeated than to attack barbarically at this very moment.
And it was in those streets that Zen remembered one of his friends, Della.
Della is a classmate of Zen who is good at curse magic and dark magic. The power that was considered taboo was identical to the magic of the demons who were their enemies.
Then about the dark magic, it was actually not a suitable name for him. Dark magic is a category of magic that is still unknown — unknown. The potential of dark magic is unknown, its impact remains to be researched further, and the type of unknown magic is dangerous when an accident occurs. Of course, the most dangerous reason is that there is no truly effective counter to counter the effects of these unknown magic.
Della, as a hero who has magic is too unique, he does not get training like the others. In addition to basic training, he studied his magic self-taught inside his secluded room. Because of the secluded room where Della was, Zen got through the hallway like a corridor inside the dungeon. And then at the end there is a stone door that is cold to the touch is also heavy.
"Was the kingdom setting it up or did Della herself decorate it? The taste is pretty bad if it is the second one," murmured Zen.
Zen opened the stone door.it had just opened, so be welcomed by the cold wind that blew past him. And before him, he saw Della playing around with a magic circle that was emitting a dark purple light with violet lightning occasionally striking from there.
It looks like Della is inside. She is a short girl with messy hair. He wears a jacket from his home world that has now been tattered. The clothes he was wearing were still the same as when he was summoned here. With a bad look because it is damaged of course.
"Yuhu~ long time no see, Della," said Zen.
Della stopped her experiment. He turned around and looked at Zen with his completely displeased face. "What's wrong? How much do you like to bother me?"
"I'm sorry I interfered. It's just, why don't you get tired of being in this gloomy room all the time?" Zen shrugged his shoulders while smiling kindly. "Don't want to go for a walk?"
"Walk? Impossible!" Della's voice rose when she said the last word. "For an asocial like me, being in a social environment for too long is like a nuclear worker being exposed to radiation. There's no way I can hang in there."
'Your asocial level is already too extreme, ' inner Zen.
"After all, what's the urgency until you meet me?" ask Della.
"I want to gain new strength. Previously I had obtained the Eternity of the Phoenix and had unlimited life force. Now I think: What if we make magic that can absorb the life force of a person and turn it into magic energy? If we use my unlimited life force, we should have unlimited resources, right?"
Della chuckles and laughs. The louder and more craze that made Zen speechless with a flat face without the sense of interrupting. "You want to use yourself as a 'energy source'? It was totally unexpected!" He continued laughing madly for a while.
"Do you want to help me?" Zen gave off his fighting aura.
Della was silent. A sense of terror from the Zen aura spread across his back. "Of course I'll help you. But after that, I'll ask for your help to perfect my magic."
