"This... sir, can you please move the dagger away a bit? Feili, I'm so scared!" There's a scene in this world called "a smile that charms hundreds", and it's exactly like this right now.

  The woman controlled by Raven turned her face towards the light source, slowly shedding her cloak, revealing a pitiful and frightened face, more importantly, that beautiful and sexy curve was revealed without any reserve under the half-turned body.

  What a devilish figure, with an ungraspable peak, a waist as slender as a water snake, and that plump buttocks trembling slightly in fright, inadvertently touching Raven's abdomen. And that calamitous, exquisite melon-seed face, with watery eyes that are even more captivating under the lightly trembling long eyelashes.

  Levin gently picked up the beautiful brown-haired girl's hair and sniffed it.

  So fragrant!

  Her left hand involuntarily wrapped around the beautiful woman's soft and smooth small waist, while her entire body pressed forward from the front.

  "Ah——" The beauty seemed to be pushing Raven's chest with one hand, as if she was both refusing and welcoming him.

  The next moment, she let out a shrill scream. The reason for the scream was because Raven had activated his Shadow Flame form.

  Although it was just a simple touch, the system determined that this was an attack, so it decisively dealt 20 points of damage to the opponent.

  20 points of flame and dark damage. If the beauty in front of him was an ordinary human woman who wasn't a professional, she would already be dead.

  Unfortunately not.

  The scream was cut off halfway through, as Raven's other hand had quietly moved forward, the Black Moon Blade inserted half a centimeter into her neck, fresh blood seeping from the long, slender column of her throat.

  Lei Wen doesn't have much good to cherish and pity.

  Only a devil can have such a devilish figure!

  "Are there any other tricks up your sleeve, Miss Desire? I never would have thought that even in human form, your blood is bright red." Raven had just finished teasing when his right knee suddenly struck Desire's abdomen, and then his left hand behind her waist suddenly moved, grabbing the beauty's occipital bone, mercilessly pressing Desire's entire body down to the ground.

  Leiwen's foot stepped on the tempting demon's bare back. His left hand quickly tied up the demon who didn't dare to resist with a living rope, and his right hand continued to press the Black Moon Blade against her neck.

  Just now, when I touched the waist of someone's house, the thing was already in my hand. That is the key to Gargos' treasure house, even if Gargos has been hanged. Without a key, it would take a lot of effort to force it open.

  Levin didn't think the Desire Demon would dare to revolt again. Since its birth from the 9th level of Hell, Desire Demons were never a powerful vanguard species. A normal Desire Demon's challenge rating was only 32, barely bronze rank. Levin didn't consider this Desire Demon's combat strength at all.

  Leiwen values other things.

  "Stop it. Don't hurt me, whatever you want, Freya will give it to you." The demon of desire said, trembling.

  "Put away your devilish tricks, I bet a dime you're not actually named Feri."

  The demoness couldn't understand what a "mole" was, but that didn't stop her from sensing Raven's distrust.

  "I..."

  It seems like he wanted to say something but stopped himself. On the other side, Raven had already received a system prompt:

  "You were charmed... You need to make a will save, your Iron Will specialty kicks in... You passed the save, you are unaffected."

  Leiwen didn't even give her a slap, just coldly sneered: "Enchanting? Sorry. Even if it's violent enchantment, I can withstand it, little demon of desire, you're not enough to deal with me!"

  At that moment, the demon really felt a hint of shame. Raven's words were absolutely the greatest insult to her capital and talent. But as a cunning devil, she firmly believed that as long as Raven didn't kill her instantly, she still had a chance to turn things around.

  She's overthinking it.

  "I met you by accident. I don't have much time to spare on you. Once the Saint Warriors burst into this room, in order to prove that I am a friendly ally, I can only take you down with one hand. Alright, here's the condition: You swear your devil's true name, in the name of the Naihe River, and pledge unconditional loyalty to me, Raven, unilaterally, and I will spare you."

  As soon as Raven's words fell, the demon immediately realized that Raven was by no means an outsider. In terms of demonic knowledge, Raven was absolutely an expert among experts.

  The ordinary contract of the God of Contracts cannot bind demons and devils. There are always fools who sign a series of contracts that they think are secure with devils, only to be double-crossed by them.

  A safer bet is the soul contract, which has been ridiculed in previous games, and even a team of 100 lawyers can't confirm whether a 1,000-word contract has any loopholes or pitfalls. Almost every day, someone gets screwed over by a devil's soul contract and ends up selling their own soul for nothing.

  The only thing that has a strict binding force on both demons and devils is the 【River Styx Oath】, which is a weakened version of the 【River Styx Covenant】 used by gods, but it also has an astonishing effect.

  The Stygian Oath system is a tradition that can be traced back to before the birth of the mortal world. No one knows which god first proposed this system, nor does anyone know which god made it come true, and even less so how the River Styx executes it. However, it is an oath that can bind even spirits, the most stringent, and the most important.

  Imagine a scenario like this:

  One day, Charlotte, the spider who had deceit and betrayal flowing through her veins, suddenly dragged Raven in front of her and said to him: "I've decided that tonight I'm going to go and steal back my husband, the god of justice, Tyr."

  It's obvious that up until now, everything has been a pack of lies and jokes.

  But if Rose adds this sentence: "Damn it, I swear on the River Styx that what I just said is true."

  So Raven can immediately consider whether to inform Tylor that tonight they will form the Hu Duo, oh no, it's the Anti-Robbery Wedding Team.

  Whether it be a demon, devil or deity, when he uses the River Styx oath (covenant), he had best keep his promise, for the penalty for breaking it is most terrible.

  If a god breaks the River Styx oath (for example, Arachne), first she will be stripped of her divine status and should become an ordinary spider. She will be transported to the fourth layer of Phlegethon in the myth of Tartarus, where she will be imprisoned for five thousand years in the fiery abyss responsible for punishment.

  The only property of the Inferno's flames is to keep the oathbreaker in a state of being unable to die. However, aside from causing extreme pain, the flames can also gnaw at even the strongest wills, and when the oathbreaker's will collapses, that god may die.

  Her pastor will lose all his divine powers and there is no way to contact her.

  Think about it, even a god's oath has such severe consequences, let alone ordinary demons or devils.

  So 'Fēi Lì' replied firmly: "You lowly mortal, don't even think about it! I'd rather die!"

  "Oh, is that so?" Raven's left hand emerged to gently stroke the demon's left shoulder, pulling down his shirt: "What do I see? Oh, a mark of defeat engraved on your shoulder."

  "...the demon gnashes its teeth and refuses to let go even in death."

  "I recall 'failure' being ranked sixth among the things that demons fear most. Am I right?"

  “……”

  "Let me think, a failed succubus who died outside of the 9th level of hell in Barto. If no one helped her, she would have revived herself after 99 years. But if her superior helped her, she would revive quickly. However, what awaited her was..."

  At this point, the demon of desire under Raven's feet had begun to tremble uncontrollably.

  "The fourth thing that demons fear most - her direct supervisor, and the first thing that demons fear most - demotion."

  His trembling has completely stopped and has reached a state of extreme weakness.

  "Oh, what will you become? Your superior wouldn't be so kind as to let you enjoy a demotion in disguise, turning into a stupid and crazy demon like the River Styx's memory thief. So... becoming a low-ranking demon is your only outcome."

  "No! No! Don't say it..."

  A beautiful succubus who once had a stunning figure and drove all males crazy, due to her failure, ultimately found herself trapped in a miserable, dirty, and ugly demonic form, assigned to perform the most shameful tasks, subjected to the ridicule and humiliation of her former colleagues for millions of years, becoming a cautionary tale for countless demons.

  This scene is terrifying just thinking about it.

  The demon collapsed.

  She thought Raven was more devilish than the devil himself.

  At this moment, she even prayed for a few holy warriors to rush in, so that she still had the opportunity to muddy the waters and see if she could complete her mission.

  "Alas, Raven dealt the final blow: 'Oh, what's this? The plans for toppling three human empires?' Raven, who was also fluent in Devil's Tongue, easily shattered the demon's mental defenses."

  This is the demon king's last hope, as long as this massive subversive plan that has spanned three generations does not leak out, then the mission will not be considered a failure. Now, whether or not it fails, is entirely in Raven's control.

  "I, Melissa Igana Jeszanna, swear on the River Styx to pledge my loyalty to Master Raven. From this moment on, my soul and body are properties of Master Raven... The oath of the River Styx is established." As soon as she finished reciting the oath of the River Styx, Melissa seemed to have exhausted all her energy, fainting and collapsing onto the ground, motionless.

  Levin wasn't worried at all that Melissa would perjure herself because once the River Styx was involved, if she said anything other than her true demonic name, the oath wouldn't take. If anyone tried to fake it, they'd be unable to control their voice and unable to say the words of the oath.

  Forcing a demon to surrender to oneself was originally an impromptu idea. Because Raven had offended the god of thieves to death, the largest source of intelligence was gone, and the Thieves' Guild would not accept Raven's business with the Kingdom of Golanpais even if they didn't kill him. To develop, one must have their own intelligence system.

  The idea of the original text is just that simple.

  However, after hearing Melissa's full devil name, Raven was completely unable to remain calm.

  Because this name is exactly the same as that of a female devil who rose to become the Demon King in the chaotic years at the end of my previous life...

  Whoa! I seem to have picked up an incredible guy!
