The Lightning Dragon Knight

Chapter 34: History of the Devil's Treaty of the Kiyomizu Clan

About a thousand years ago,

The news of the death of the Five Strongest Dragons and Master Siegfried and the sealing of Lucifer, has been widespread.

The masterminds of this widespread news were the remaining six demons from the Seven Deadly Sins. They did not accept the sealing of the king and the leader of the demon race by the dragon nation.

Six demons from the Seven Deadly Sins plan to take revenge against the dragon race. They invited the other races who supported the idea of the demon race to attack the dragon race and its allies.

The races that belonged to the demon race alliance were the vampire race, some experts of the human race and of course the demon race itself. The alliance formed by the demon race was led by Asmodeus, Leviathan, Belphegor, Beelzebub, Mammon and Satan.

Meanwhile, the alliance formed by the dragon race, consisted of people from the elf race, the dwarf race, the human race and the dragon race itself. The alliance was led by Jinlong the golden dragon, Heilong the black dragon, Honglong the red dragon, Violet the queen of the elf race and Shuilong the water dragon.

War finally broke out. All fought bravely. Technique after technique and style after style has been shown by both parties. But no one wants to give up. Victims fell. A thousand... Two thousand... Three grand... The casualties keep increasing. Whether it was from the stronghold of the dragon alliance or the demon alliance.

The war lasted for months and caused the casualties of more than ten thousand warriors. Until finally, the dragon alliance army managed to repel the demon alliance army.

The entire army of the demon alliance was wiped out by the dragon alliance army. Meanwhile, the six demon alliance army leaders, suffered severe injuries that made their cultivation drop by several levels.

This caused great losses to the demon race and the vampire race to the point of alienating them from the rest of the world.

Meanwhile, the dragon alliance also suffered heavy losses due to this failed war of revenge. The dwarf race disappeared from circulation after its entire race was slaughtered by the demon race troops that secretly slipped into the dwarf race's domain and massacred them all in one night.

Not only that, the elf race also almost disappeared from circulation after all its leaders died on the battlefield.

"Why can't it? We still have to avenge the king! The dragon race must be responsible for the sealing of our king!" said a man in red with two twin horns bent backward.

"Shut your mouth, Satan!" reply the other man who has black skin with two small horns that protrude forward while slapping the cheek of a person named Satan.

Plaque...

"Don't you see how much loss we've been through the failed war of revenge you proposed!" continue the man.

"I know, Leviathan! But, aren't you envious of seeing them all getting stronger, whereas we're like the trash of society that's been wasted!" shout Satan.

"I am jealous! But I still have a brain! Not like you!" reply Leviathan with a loud tone.

"Already, Leviathan! We better see Belphegor, Mammon and Beelzebub now! After that we can play!" ask a woman with red skin, red eyes, black hair, and a large chest.

"Wait a minute, Asmodeus! I still have to teach this selfless demon a lesson!" said Leviathan then hit Satan hard to make Satan thrown far out of the room. The punch also caused an explosive sound that attracted the attention of some of the demon race.

"Go from here if you still want to avenge the king!"

Brakes...

That was Leviathan's last words before slamming the door with his foot.

"Look! You will regret it when my revenge plan succeeds! Just look!" satan shouted and left the place.

Months had passed and the remaining five members of the Seven Deadly Sins had not heard any news of Satan's whereabouts.

They even thought Satan was dead. But, that supposition was soon they tepis, because they remembered that the Seven Deadly Sins had been endowed with immortality as long as there was still natural energy around them.

"Leviathan, do you think Satan is alive?" ask a man with blue skin and blonde hair.

"Of course I remember! But, aren't you worried about him?" ask Belphegor again.

"Well... I'm worried about him too, Belphegor! Hope he doesn't bother with that rage mode!" leviathan lirih.

Meanwhile in the human world,

DUUAARR...

Clangs... Clangs...

Swosh's...

A loud explosion was followed by a strange mechanism. Then, a demon with black skin appeared, two large horns curved backwards, white hair and beard and only wearing a leather trousers without a top shirt.

"Haha... I can finally be free again!" the devil is happy.

"Congratulations on his freedom, my King Lucifer!" satan manages to free Lucifer from the seal that binds him.

"Thank you, Satan! If it wasn't for you, maybe I'd be locked up in there for a very long time!" reply Lucifer thank you.

"Hamba wouldn't have been able to do this if it weren't for Yukio, Master!" satan said as he pointed to a man standing behind him.

"The name is Yukio Kiyomizu! He's the one who helped my servant to set you free, sir!" satan introduces Yukio.

"Oh, so you helped Satan to set me free?" asked Lucifer who was replied nodding by Yukio, "So! All right, take this! Think of it as a thank you!"

Lucifer throws something heart-shaped at Yukio. Yukio quickly caught him using both hands. He then looked at that heart-shaped thing.

It would be a surprise to find the enormous demonic energy within the heart-shaped onyx stone artifact.

"Yes-Your Majesty Lucifer, what did you give to the servant?" tanya Yukio stammered.

"That is the Heart of Satan! One of the artifacts I made before I got locked up here!" answer Lucifer.

Bruck...

"Hamba, Yukio Kiyomizu and the descendants of servants! Swear to be faithful to Lord Satan and Lord Lucifer! To the end of the world!" yukio said loudly while kneeling.

"...That's its history!" yuki.

"Hoam... Like the history lessons at my academy! Very long and wide! I almost fell asleep!" said Rai slowly while rubbing his eyes using the index finger.

"Haihihah... You asked first!" Miyuki.

"Auntie, are there no other artifacts in this residence other than that Demon Heart?" asked Rai after finishing rubbing her eyes.

"No! There are still some other artifacts! I also have something for your little spirit!" yuki replied which made Rai's brows twitch.
