The demon king who appeared in front of Su Yan in front of him was only about five meters tall, and compared to the demon breed, it could already be regarded as petite and mini. But the momentum it exuded was definitely enough to make any creature that didn't have the same strength as it could be feared.

Just because of two words.

Beelzebub.

The Demon King is the second highest level existence in the pyramid ranking of the Abyss Purgatory Plane, second only to the Great Demon King.

It stands to reason that such beings cannot break through the blockade of the world wall and appear in any other plane. Even if it's just a doppelganger or projection, it's even more difficult than a vengeful spirit. It will be difficult for Tirsulas to come to the Essence.

In other words, if the spirit of vengeance. If Tirsulas wanted to descend into a physical realm as an ontological being, it would be very troublesome, but it was not impossible. However, if a demon like the Demon King, which can almost be said to have touched the ceiling, wants to descend directly in his main body, then the difficulty will increase exponentially, and even if the entire population of an empire is sacrificed, it may not be successful.

Because, this is already the extent to which it has touched the core laws of a dimensional world.

Of course, it's not entirely without loopholes, but the average person certainly wouldn't want to do that.

For example, if you have a sacrifice with strong enough energy and a token that can directly communicate with the origin of the demon king, and this demon king is still in a very weak situation, then it is possible to summon the body of a demon king completely.

It's just that even a very weak demon king is by no means something that ordinary people can deal with.

This can be seen from the fact that the person who built this sealing place in the first place could only seal this demon here, and the other party could not control this demon king.

"My name, O'Hara. He is the ruler of the 888th layer of the abyss, the king of the great Quiles Demon Dragon Clan. The demon with a hideous face looked down at Su Yan and Anna, and then let out a loud noise that even caused the entire ruins to shake, "Kneel!" Mortal! Honor the Great Demon King! I will grant you a painless death! ”

With the roar of the demon king in front of him, a strong smell of sulfur even began to waft into the surrounding air.

And the obsidian-like armor on the demon's body also began to have red magic patterns appearing, which made it look even more powerful and terrifying.

Su Yan thought with his toes and knew that the name of this demon must be a pseudonym.

Because no demon will ever give his real name, after all, for a magician or someone with some special means, once you know the real name of a demon, it means that you have completely mastered the ability to control the other party. So obviously, the name "O'Hara" that the king of the Quiles dragon clan said must be just a pronoun.

But these are not what Su Yan needs to care about.

What he really cared about was the smell of sulfur that was beginning to fill the air around him.

Inside, there was a mixture of sulfur gas.

For Su Yan, it is naturally a degree that can be ignored, but for Anna, it is by no means something that can be ignored.

After only two or three seconds, Anna's face turned a little pale and she began to cough violently.

This is clearly a sign of having been poisoned.

The milky white flames burned around Su Yan out of thin air.

These flames dispel the smell of sulfur around them, but instead the temperature around them is dropping dramatically.

White Flame of Bones!

It was only a matter of seconds, and the surrounding walls, floors, and even the dome had begun to have frost condensing rapidly, and even the breath began to appear ice mist, as if the cold aura that would completely freeze the soul continued to emanate.

Around, small sparks began to burst out.

It was the energy of the hot breath of sulfur and the cold breath of the undead.

A warm current, through Su Yan's palm, began to flow into Anna's body, which made her face quickly become ruddy.

【Secret Technique of the Undead. Warm current of life].

This is a special skill that belongs to the undead race, and it is also the only ability that high-level undead creatures can use to heal non-undead creatures. But the price is that it needs to consume the caster's own vitality, and the conversion ratio is two to one: Su Yan needs to consume twice as much vitality in exchange for a trace of Anna's vitality recovery.

"Undead?" O'Hara's hideous face showed a look of surprise, "No...... Not your average undead. Undead Lord! ”

But Su Yan didn't pay attention to O'Hara, but gently put Anna, who had recovered from her physical condition, back to the ground.

The little guy grabbed Su Yan's hand, and his face looked a little flustered: "Dad? ”

"It's fine." Su Yan said softly, "Do you remember how to get back to the room we first came into?" ”

"Hmm." After a moment's hesitation, the little guy nodded.

"You go there and wait for me first." Su Yan said softly, and at the same time, with a wave of his right hand, there were six more magic arrays emitting a miserable white halo on the ground, "They will protect you, don't worry about the monsters along the way." Wait there for me to go back. ”

Among the six magic arrays, what gradually emerged was the black knight Byron and five necromantic warriors.

In the room where the ruins were the starting point, Su Yan had already identified several of the spells in it, so he couldn't be sure if the undead creatures he had summoned would be able to enter it together. Moreover, the current defense mechanism of this relic is still in operation, and it is possible to refresh a wolf pack of demonic beasts at any time, and it is absolutely impossible for the Black Knights and Necromantic Warriors to safely escort Anna away.

Therefore, in order to pursue the greatest safety, Su Yan simply sacrificed the two black knights, so as to completely repair the black knight Byrons.

After all, in terms of pure combat effectiveness, the Black Knight Byron is completely above the two Black Warriors and the five Necromantic Warriors.

"Protect her." Su Yan reached out and gently wiped it on Anna's forehead.

This is the mark of the dead.

Normally, tagged creatures attract the attention of undead creatures. But when this mark is cast by Su Yan, then it contains another function: protection.

All the undead creatures that belong to Su Yan's manipulation will be desperate to protect Anna.

"Let's go." Su Yan said softly, he reached out and gently rubbed Anna's head, "Go back to the camp and wait for me." ”

Anna looked at Su Yan, from the beginning to the end, she didn't look at herself, she knew that the current situation was very critical.

Naturally, he also understood the hidden meaning of Su Yan's words.

Not for her to wait for him in that room, but for her to go back to the main plane through that portal.

So the little guy didn't make a fuss, but nodded very obediently, and then ran cautiously and quickly towards the way he came. Behind her, there are six undead creatures led by the Black Knight Byrens, especially the Black Knight Byron who has the equivalent of hero-level strength, as long as it does not encounter more than a hundred large-scale wolf pack monsters, it can easily solve these troubles.

O'Hara looked at Anna, who gradually disappeared from his field of vision, and then his gaze fell back on Su Yan's body, and he couldn't help but pout: "It's really prudent, and you haven't relaxed your vigilance against me from beginning to end." ”

"In the face of a demon king, you can't be too cautious." Su Yan said in a deep voice.

And when he finally didn't need to think about Anna's safety anymore, his whole person's momentum began to rise.

After coming into this world, this was the first time he really showed his fangs.

Unlike before and the Spirit of Vengeance. In the battle of Til Sulas, although Su Yan also broke out with a considerable degree of combat power, he even ended with an eighth-order combat skill and directly killed the opponent in seconds. But in that battle, Su Yan was more of a "strategy" to win: for example, let the black knight Byron attract hatred and interfere in front, so as to create an opportunity for him to kill with one blow, so in fact, he can't be regarded as going all out in the real sense.

Only at this moment can Su Yan be regarded as truly going all out.

It is precisely because of this that Su Yan chose to keep Anna away from here.

When he had to give it his all, he couldn't keep Anna safe. Moreover, with the strength of him and O'Hara, once they fight with all their might, the energy fluctuations generated are by no means a joke, with the current situation of Anna, even if she is only affected by one thousandth of the force, I am afraid that it will be a broken end.

This is something that Su Yan can't accept no matter what.

"Hmm...... I'll admit that I did underestimate you before. O'Hara straightened up, his expression becoming solemn, "As the Undead Lord who has the right to speak to me on an equal footing, I grant you permission not to kneel before me. ”

O'Hara's tone changed slightly, and he no longer referred to himself as "I".

"Huh." Su Yan sneered, "Demon King, have you mistaken your identity?" ”

"Not really." O'Hara shook his head seriously, "You're just a king, and you haven't gained the authority of a king. Therefore, your identity and mine's identity are equal, and only after you obtain the authority of the Thirteen Kings will your identity be one level higher than me, and you will become an existence that is enough to be on a par with the Great Demon King. ”

Su Yan's eyes narrowed slightly.

From O'Hara's words, he realizes a key problem: his profession is the Undead King, but it is clear that he is really the Undead King. At the very least, in front of O'Hara, he was only the Maharaja, a successor who had not yet attained the authority of king, but was already eligible to compete.

Although O'Hara's words made Su Yan feel a little surprised, the issue of the Undead King was not something he needed to consider for the time being.

The real problem he needs to think about at the moment is how to defeat the demon king in front of him.
