Having traversed countless realms, can you possibly be as clever as me?

"I am... Leviathan, and I've been watching you... for a long time!"

"Make a deal with me... and I'll give you... the reward you want."

'Detected a deeper penetration of the Jealousy pathway power; your Inscription skill [Seven Seals Lv3] has been upgraded to [Seven Seals Lv4]!'

Changing the style doesn't stop it from killing! : 150. [Black Bullet Complete] Leviathan's Deal (Bonus Chapter, Please Vote!)

In fact, seven days before he witnessed this global extinction, Tsurugi had been receiving an unexpected surprise.

'A deeper surge of jealousy has been detected; you have gained the attention of 'Leviathan'!'

During this period, especially while he was taming these Gastrea creatures all over the world, he kept receiving such prompts.

He didn't understand why Leviathan would pay attention to him. Had he done something that violated the original sin of envy?

Was I ever jealous of anyone?

Screw it, I could never have done something so shameful!

I kill anyone who displeases me!

However, at the time, Tsugumi was preoccupied with how Tutu had saved this world from these little devils, so she didn't pay much attention to this issue.

Even now, it seems that Leviathan has found us through this world-destroying colossus!

'A deeper surge of jealousy's power has been detected; you have received a quest from 'Leviathan'!

Quest: The Foundation of the Giant Beast

Description: Leviathan wants you to collect monsters or special life forms from various worlds to fulfill its requirements!

The reward has been distributed in advance; you have obtained the 'Mark of Jealousy'!

'Detected a deeper penetration of the Jealousy pathway power; your Inscription skill [Seven Seals Lv3] has been upgraded to [Seven Seals Lv4]!'

【Seven Seals Lv4】

'Seven deadly sins, seven powers, seven spheres of authority, seven crowns. You are a favorite of Hell, favored by multiple realms simultaneously. This is a great honor only a demon god can receive—the favor and blessing of multiple sinful powers! At this moment, you simultaneously hold the crowns of the realms of desire, wrath, and pride, and you have four opportunities to gain a demonic body and power (two already used).'

'Gastrulocytes' have been included in the database!

Dongjiang felt completely bewildered at that moment.

It was somewhat understandable that he was chosen by rage, desire, and pride, but how did he suddenly become chosen by jealousy?

He didn't understand, but that didn't stop him from trying this new mark—though he didn't gain power, the mark itself would tell him how to acquire it.

Then he seemed to realize why he had been chosen by Leviathan.

The power of envy requires him to constantly collect samples of creatures from different worlds. These unique life forms will sink into his imprint and be passed on to Leviathan in the endless sea of ​​rifts in hell.

At the same time, these forces will also be fed back to his physical body, giving him the ability to enhance and modify a specific body through genetic and biological means.

In short, this is the authority of a biological system.

As for why Leviathan suddenly chose him...

Perhaps because—

Just like when Tsugumi was chatting with Asmodeus before, she heard some gossip about the Seven Deadly Sins from her.

Asmodeus: Leviathan? She's just a complete idiot who eats and sleeps all day!

Tsuruga blinked, looked at the clumsy-looking giant warrior, hesitated for a moment, and said...

"So, you just want to find a companion?"

......

"Afterwards his ways shine, making the abyss seem like white hair. There is no one on earth as fearless as he has made; he despises all that is high, and reigns over the proud sea creatures." — Job 41:12 (Old Testament)

Leviathan is not a demon, or rather, its existence is incompatible with the other six demon lords.

It is not a fallen angel, nor is it in any version of the Bible. While figures like Belial and Beelzebub are at least considered fallen angels in some versions of the Bible, Leviathan is simply a beast, regardless of time or place.

Tracing back to its origins, He was the god of abundance in the eyes of the Canaanites, who was slain by Baal. However, in the Hebrew Book of Isaiah, He was described as a "crooked serpent," transforming into the evil god Litan, who later became the serpentine sea monster Leviathan.

He is a seven-headed serpent, the king of the sea. Legend has it that on the sixth day of creation, God created a male and a female monster. The female is Leviathan, who dwells in the sea, while the male is Behemoth, who reigns supreme in the desert. When the end of the world comes, Leviathan and Behemoth will become sacrifices offered to the holy.

and then?

Death

Descriptions of Leviathan are scarce, remarkably so. In the Old Testament, He is merely a chaotic dragon, a created behemoth. But in the New Testament, He is transformed into a demon who rebels against God and seeks to destroy the world.

Did she do something bad?

The answer is no! You won't find any accounts of Leviathan's evil deeds, or even anything about the evil deeds of the demon of envy. On the contrary, both versions of the Bible mention that Leviathan and Behemoth (who doesn't even appear in the story) were killed before Judgment Day to entertain everyone.

You might even wonder – why would such a female sea serpent be considered a demon king?

The answer is laziness.

Yes, you heard right. In Asmodeus's account, Leviathan became the Demon King of Envy simply because God was lazy.

It existed at the beginning of creation as the ruler of the ocean, the mother of animals, and a symbol of chaos that contained creation and infinity. However, after creation was completed, the world no longer needed such a large mother ruler.

So the Lord sent it to the sixth level of Hell, to that endless sea of ​​rifts, a superfluous part of creation.

But Leviathan didn't react at all. Or rather, it probably didn't even notice any change. After all, it was all swimming, so what difference did it make where it swam? This place was even bigger! It didn't sense anything amiss at all.

Even if Lucifer were to create humankind and then fall from grace due to original sin, to her, Lucifer's rebellion against God and his fall from Godhood would be nothing more than a trivial matter of "a lot of little people suddenly falling from the sky."

The original sin of envy is actually very close to Mammon's greed. It represents the sin of a person who is full of desire for things that are better than himself but does not try to make an effort to obtain them, but instead tries to take them away.

But what does that have to do with the giant snake that eats and sleeps, and sleeps and eats? Who could Leviathan be jealous of?

The Envy Ring is also the only realm without demons in the true sense. Here, there are only sinners who fall endlessly into the ocean, repeatedly drowning and being devoured, and who are constantly threatened by the deep sea, as well as the spirits of those who fall into it and become sea beasts that devour sinners.

If one were to call the latter a demon, it wouldn't be entirely wrong, but they lack any of the characteristics of demons from other rings, and most of them even lack intelligence...

If you were to ask why the sin of jealousy is so unique, Asmodeus could only give a vague answer.

"Just think of it as the old man having nowhere to put his pet, so he might as well give it a name and keep it as a pet—Quack!!!"

Tsugumi gave a brief summary, which roughly translates to:

God kept a fish in his house. Later, he thought the fish was too big and wanted to keep other fish, but he couldn't bear to part with this pet, so he put it in the pond in the backyard and let this unpicky fish clean up the messy garbage.

Yeah, that's roughly the idea.

The image of a lonely and nostalgic old man leaps off the page...

So don't talk about original sin. Leviathan herself doesn't even know what the original sin of envy is. She merely holds the mark, rather than being the one who embodies it.

However, this is the norm in Christ's Hell—the original sin demons are not like some cesspool world, where the gods seem to be the embodiment of concepts themselves. They are not the concepts represented by these original sins, but merely their drivers and forerunners.

You can't say that someone only eats crabs just because the first person ate one—they are the masters of original sin, not its slaves.

Why did Leviathan make this request to Tsurugi and so generously provide the mark directly?

Tsurugi asked directly, and the somewhat simple-minded female snake gave a straightforward answer.

—Want more 'Behemoths'

"What do you mean?" Tsurugi asked again, and Leviathan patiently explained.

Behemoth does not actually refer to a giant beast like herself, but rather to countless other animals on earth and in the sea; its Hebrew meaning is "herd of beasts."

Behemoth, who accompanied Leviathan, is like the other animals God created to accompany his pet.

Leviathan, wandering the seas, asks for nothing more than more diverse companions. And it has its eye on Tsurugi because he can freely travel between many worlds.

“You are a… good person.” Leviathan’s voice was simple and honest.

"The young animals deserve...care...your anger...wasn't directed at...they."

"Comrade, this is fun! I can mark you... help you settle these cubs, turn them into 'Behemoths'... to keep me company!"

Leviathan spoke haltingly.

"Wait a minute, that 'big brother' thing doesn't work here!" Tsugumi waved her hand, looking somewhat alarmed.

"I won't do anything like having little girls combine with monsters or beasts, absolutely not!"

"That's not what I meant..."

Leviathan explained somewhat slowly.

She could do the orc fusion, but there was no need for her to. The spirits that actually fell into the Sea of ​​Endless Gaps were beasts they had transformed into, but if Leviathan so desired, they could become beings indistinguishable from the lesser demons and sinner demons of the other rings.

Even if Leviathan has always been too lazy to care about such things, she is still a true demon king of original sin.

However, she might prefer to transform hell from a place with only a single group of 'people' into an environment with more complex 'Behemoths'.

When these cursed children reach the Envy Ring, Leviathan will create a batch of lesser demon bodies for them according to their genes. As for the living environment—the space of Hell is infinite, and its resources are also infinite, so it is not difficult to find a better place for them to live. Moreover, once they become demons, they basically don't care about these things. If things get really bad, they can just go to the human world.

"Did you hear that? What are your thoughts?" Tsugumi turned to look at the little girls and asked, tilting her head.

Silence, bewilderment, but also understandable, after all, probably not many of these little girls have ever been to school, and they have no concept of heaven or hell.

A small hand was raised; it was Tina. She lowered her hand and asked expressionlessly.

"What would happen if we turned into demons?"

"Let me think... Immortality? Eternal life? Unless you foolishly mess with mortal souls, you're unlikely to be targeted by angels and holy beings. And..." Tsugumi stroked her chin.

“I’ll join,” Tina said without hesitation.

Just kidding, what reason is there to refuse? What's wrong with becoming a demon? It's certainly nice to enjoy heaven as a human, but being a demon is at least a legitimate career path!

It's like someone from the East went to the underworld to become a ghost messenger or a ghost soldier. If you call me a lackey in front of the gods, I won't argue with you. But if I go out of the underworld to meet mortals, what will you call me?

These little girls, lacking any independent thought, readily agreed, since they really didn't have much of a choice.

Tsugumi quickly drafted a contract, and after signing this agreement with Leviathan, which neither of them could break, Leviathan let out a happy whimper.

"The cub...I'm so happy!"

The giant warrior has disappeared, and there's nothing left for Tsurugi to do here.

Then the system suddenly popped up again.

'You have completed the world quest and received the reward: Tiger Talisman!'

"What the heck?" Tsurugi stared at the talisman with the black and white tiger symbol in his hand, completely bewildered. What was his world quest again? How did it get completed out of nowhere?
