How rare is a demon king?

  Asmodeus, the Overlord of the Nine Layers of Baator, emerged from the pantheon of gods as a distinct entity, and since then, each layer of the nine hells has been ruled by a single demon lord.

  These kings were all experienced in cruel slaughter and hellish politics, and they carved out their own territories.

  So, no matter which of the nine-layered hell kings looked down on Gaggs, they thought that his title as the tenth king of the nine-layered hell was just a joke. Because from the very beginning, Gaggs was a god in the human camp, and secondly, if he were to use his methods in the nine-layered hell, he would be completely consumed without leaving any residue.

  It's just that Garsus had a stroke of bad luck and was able to seal the gods on the mainland of O'Creat.

  This result also made the demon kings quite envious. In the early years, Asmodeus made an oath to stand alone and separate from the gods, swearing not to become a god. The consequence is that although the kings in the nine layers of hell are individually powerful enough to rival the gods, some even strong enough to overthrow some mid-level gods, including Asmodeus, they are all only half-gods due to their lack of divine authority.

  Now, a demon with the potential to become a devil king has sworn an oath of fealty to Raven, declaring himself to be Raven's servant, it feels kind of touching.

  It was originally just a small accident, but it became another new possibility.

  Leiwen wouldn't be so foolish as to dig a hole for someone on one side and then immediately tell them they have the potential to become the Devil King.

  But after the big stick, carrots are still needed.

  As the devil, the biggest characteristic is ambition.

  Simply taming her and extinguishing her ambition would only ruin Melissa's potential as a future devil queen.

  "Don't be so disheartened, I only need intelligence, accurate intelligence. The rest of the time, you can dispose of yourself. Of course, I won't declare ownership over you to anyone either." Raven smiled mysteriously and said: "I can tell you a secret about Leviathus, the fifth layer lord of the nine-layer hell. You can use it to exchange for a good position with Glasya, the sixth layer lord, the Desire Demon Queen."

  Melissa's eyes lit up instantly. Any devil would know that Gracia had never let go of her hatred for Prince Levisetus, who killed her mother...

  Melissa was unexpectedly taken care of, and Raven joined up with Sains who had rushed back, advancing further into the depths of the underground palace.

  The guys in the Holy Sword series have one thing that's particularly good. That is, they all use powerful oaths to bind their actions. This oath gives her immense power and also makes the lord who owns this oath extremely relieved.

  Laila adopted Sain as an orphan when he was very young. As a result, after Sain grew up to become the Phantom Sword Saint, his oath was "to do anything for Laila, even if it means becoming enemies with all the gods and demons." Even after Raven became Laila's elder, the oath only changed to "to do anything for Laila and Raven, but in case of conflicting orders from both, follow Laila's."

  Levin's words were: "My new subordinate can rest assured."

  Sains nodded and continued with her guarding duties.

  The upper palace and the castle inside and out were still fiercely fighting. The devils could abandon the gold treasures here if necessary, but as long as the secret documents here had not been burned, they had to fight to the death. As devils, summoning devil allies was a regular tactic.

  After the brief chaos caused by the Saint Warrior's charge, it was discovered that the number of devils actually increased with each battle.

  However, the devil and the holy warrior have been fighting for thousands of years, especially since the holy warrior often wears heavy armor and can also use healing spells. This style of combat that combines both offense and defense also means that neither side has any particularly outstanding abilities, and they know each other's strengths and weaknesses inside out, making it impossible to determine victory or defeat in a short period of time.

  It was solely because of Raven's accurate intelligence that the Holy Knights were able to gather their superior forces and gain an overwhelming advantage.

  Of course, since there are no semi-god level demons here, it's not necessary for the Three Justices to make an appearance either.

  As the downward staircase went deeper into the ground.

  Leiwen and his party finally arrived at the lowest level of the underground palace where the treasure of Gaggs was located.

  "Raven... be careful, after all, this is a legacy of the gods." Sain said, rarely warning.

  "Don't worry, I know what's inside. The big show is yet to come. I'll take the hate, you take the main attack." Raven's words, like a magic wand, gave Sains strong confidence. In her impression, Raven's prophecies had never been inaccurate.

  Behind her. The demon Melissa no longer entangled her own positioning. For a demon, an unattainable goal in the short term would only gain her submission. The treacherous blade of the demon's betrayal could only be inserted into the spine of the top head that was almost identical to hers. Moreover, after making the Stygian oath, Raven died, and Melissa must have followed in destruction.

  "What should I do, master?"

  "Hide well, the wind. I can hear your soul calling."

  Melissa bowed and backed away.

  A large iron gate that seemed simple was unlocked with a key, and the tall double doors creaked open.

  Everyone knows this is just the beginning.

  A dozen massive and heavy stone coffins were placed in pairs against the walls. The coffins were made of granite, with bas-reliefs of strange creatures that had only skeletons. Each coffin was adorned with inscriptions in a hellish language that outsiders could not decipher.

  Levin knew that engraved above were the achievements of these devils 'before they came into being'.

  A low, piercing noise echoed through the hall, and the lid of the stone coffin burst open with a loud crash. Amidst the scraping sounds of bones and stone coffins, giant skulls over two meters tall with bony spikes on their tails slowly crawled out of their graves.

  They are bone demons, but not real bone demons.

  They had already lost their lives as devils, and they who were originally supposed to die outside the nine-layered Batuo Hell would return their souls to the nine-layered Hell and be reborn in the nine-layered Hell.

  However, their filthy souls were captured by Gaggs and frozen in this treasury, serving as guardians to repel low-level intruders.

  The Bone Devil was originally not strong, just barely at the White Silver stage. This degraded version of the Bone Devil was even more unbearable. Although they also had souls, Raven could no longer extract killing experience from such a turbid and low-level soul.

  At the flicker of an idea, Shadow Kill suddenly jumped out from Ray's shadow, harvesting these dregs like cutting grass.

  The real test is yet to come, entering the second great hall.

  This great hall is itself a gigantic prison, and when the iron-studded doors are opened, one can see at once a colossal devil - the scorpion devil.

  It's said to be a snake scorpion... but Raven always felt that the name was problematic. Because the appearance of the snake scorpion makes people easily associate it with frogs.

  The skin of the snake scorpion devil is a mixture of pale green and pink. In front of their obese body, their 6-meter height can only be overshadowed. Behind them, a pair of clumsy, bat-like meat wings, emitting a wave of sulfurous smell mixed with stench.

  His face had a wide mouth that was almost as wide as his ears, filled with sharp teeth, and countless pimples and rashes etched into it. His cheeks were smeared with thick rouge, his lips emitted a cold red glow, and around his eyes, which resembled those of a reptile, blue eye shadow was painted.

  What is most unbearable is his long fingernails that are forever colorful.

  A long face is not your fault. But if you know you're affecting the city's appearance and still want to show off everywhere, that's a mortal sin.

  "Oh, a rare visitor, I've been bored for many, many years. I hope you're not too weak, so I can thoroughly enjoy myself. Oh oh oh——what do I see? A beautiful maiden. Just right, those lustful demons have all gotten old, it's nice to change flavors occasionally. A legendary body, how delicious, this way it won't be easy to spoil."

  Occasionally, a battle intent rose on Sains' expressionless face, his eyebrows furrowed coldly at this boastful guy, and the thumb of his left hand quietly pushed upwards. His unique long curved knife quietly emerged from its scabbard.

  "I'm going to cut it off."

  "I'll just add the final blow." The ordinary snake demon's challenge level was as high as 88, this one looked like an elite, at least 96 levels, such a large amount of experience, Raven wouldn't let it go.

  Sains finally gave Raven a white eye, which was considered an agreement.

  Fight, begin!

  The Snake Scourge had a habit of always taking out the opposing mage first. On Raven, the Snake Scourge sensed a slight fluctuation in magic. So it smashed over with a quasi-magical attack.

  However, Raven was disappointed.

  This is a once-a-day usable spell-like ability 【Counter Good】, with an effect equivalent to a Lawful-aligned spell. The prerequisite is that Rayven must be of the Good alignment.

  Perhaps in the eyes of the snake demon, only a righteous person like a holy warrior can break into the evil Gaggs' treasure trove.

  "Saints, do I look like a good person?"

  "Get out!"

  The thunderstorm has yet to arrive, and the snake demon's attack is coming again.

  "You have been attacked by the Basilisk's [Contemptuous Gaze]: The Basilisk can use its poisonous gaze to contemptuously strike its opponent, dealing a mental blow. This is a mind-affecting effect that radiates out in a 36-meter cone centered on the Basilisk. All creatures within the cone must make a DC 24 Will save or be stunned for 5 seconds."

  Recently, Raven, who has been frequently subjected to will attacks, is also drunk. He is extremely grateful that he is wise and powerful, constantly tempering his will.

  It's said that if it were Asmodeus, the Overlord of the 9th layer of Hell, who came to mock Raven, Raven might still be in a better mood.

  How dare you, a monster that destroys the city's appearance and should be eradicated by humanity, come here to despise me?

  Lei Wen Huo has grown up.

  【Mid-tier Fear Spirit】plus 【Destruction Halo】fired in succession, and with one breath, he knocked off 7 points of Snake Scourge's spiritual energy. But that's not all, Raven directly activated 【Destruction Eye】, targeting the lipstick case on Snake Scourge's neck.

  "Bang—" The Snake Scorpion Demon's treasure was killed instantly.

  "Bastard! I'm going to tear you apart!" The Snake Scourge went berserk, but somehow felt a bit short of breath.
