"Woo......"

Su Yan let out a groan, and then the next moment his brows wrinkled involuntarily: "Damn! ”

At this moment, he was lying in a pile of bricks and tiles like ruins.

Not long ago, he was carrying several heavy boulders.

Not being crushed to death by these boulders, Su Yan felt that his physical strength was already amazing, but the pain from his body also made him understand that his current injuries were not light: all his internal organs seemed to be misplaced, and he would feel extremely uncomfortable if he moved slightly.

"That madman demon." Su Yan let out a groan again.

He held his breath, his right hand moving slightly, and chanting a spell like a ballad.

As Su Yan's incantation sounded, the temperature around him had begun to drop gradually, and a faint smoke spread out.

The chanting time of this incantation was obviously not short, and with Su Yan's situation at the moment, it was obviously a little difficult to chant this incantation, and sweat began to bubble up on his forehead.

In just a few minutes, Su Yan's face turned a little pale again.

But this incantation has obviously come to an end: Su Yan's voice has gradually become louder, and his tone has begun to become high-pitched.

When he finished the last syllable of praise, in an instant, countless black magic arrays were filled as far as his vision could see.

A large number of skeletons began to crawl out of these magic circles.

[Summon the Legion of the Undead].

One of the strategic-level magic mastered in Su Yan's skill list.

However, this magic is very different from ordinary seventh-order magic.

Especially in this world, it shows a completely different situation from the game.

Originally, according to the setting in "Eternity", the casting of [Summoning the Legion of the Undead] was very strict and special, and this skill could not be used without meeting the limited standards. So since Su Yan learned this magic by accident, he has only used it twice in his more than ten years of gaming career.

But in this world, things are different.

When Su Yan transformed all the corpses of the inhabitants and invaders of the Gray Sand Territory into undead creatures for the first time, this skill was in a usable state. The effect is that the undead creatures stored in the corpse bone plane can be summoned in large quantities at one time, but the chanting time of up to five minutes and the inability to do other actions during the spell casting process, and any contact will cause the spell to fail and suffer backlash, which has become the weakness of this magic.

Summoning so many undead cannon fodder, Su Yan naturally didn't want to use them to fight the Demon King.

He's not stupid enough to that extent.

"Dark Sacrifice."

Accompanied by Su Yan's soft singing, all the skeletons that had just been summoned began to fall apart one after another, and then turned into a handful of white ashes.

Only the little soul fire that had sustained these skeletons before was still floating in mid-air.

In just the blink of an eye, the hundreds of skeletons had completely disappeared in front of Su Yan, leaving only gray-white powder that almost covered the entire venue.

And those soul fires floating in mid-air also began to merge into his body one after another with Su Yan's will, and began to repair his injuries.

About a quarter of an hour later, Su Yan, who had been resting with his eyes closed, finally opened his eyes again.

A flash of light flashed from Su Yan's eyes.

His face had finally regained a little redness, not as pale as before.

Gently exhaling a breath of turbidity, Su Yan stood up from the ruin-like bricks, and then looked at the two long swords he was holding before with some pity—one of which had been broken.

He glanced around at the situation.

The damage caused by the collapse was obviously more serious than he had imagined.

The dome above had been blocked by countless broken bricks, and it was obviously impossible to return to the first floor of the ruins. And the ruins caused by the destruction also blocked the passage on both sides, although Su Yan didn't know the specific situation on the other side, but at least he could be sure that O'Hara was on the opposite side, and he would definitely not be as seriously injured as him, after all, the rock armor on O'Hara's body was not an ornament.

What Su Yan really didn't expect was that the power generated by O'Hara's trampling would be so terrifying.

The damage caused by that kick destroyed at least three layers of the ruins.

In other words, Su Yan was now on the fourth layer of the ruins.

In a way, he was going to go further than the expedition.

But at this time, Su Yan will not be happy.

Because it means that he wants to return to the difficulty of the first layer: according to the information of the previous explorers, the defense mechanism of each layer of the ruins is showing an incremental increase. If the first floor only appears with some monsters equivalent to professional-level strength, then the difficulty of the second layer will be increased to master-level strength. And in the third layer that trapped those explorers, the monsters that appeared generally had the strength of the candidate level, and there were several monsters that had reached the strength of the hero level.

As for the fourth layer......

Su Yan felt that without epic strength, he might not be able to sit here at all.

As for the explorer team and the other rescuers, Su Yan no longer had any hope for them.

O'Hara has gone to the second floor, are those guys still alive?

The demon who has just been unsealed must be weak, but now that O'Hara's strength has almost completely recovered, it is conceivable how many souls he devoured to recover his strength. Therefore, Su Yan would not think that the team of explorers, including Susan, still had the possibility of survival, and now his main concern was to return to the first floor and leave this ruin.

As for O'Hara, that's none of his business, and the commission he accepted didn't include asking him to go to trouble with a demon king.

In fact, if O'Hara hadn't shown murderous intent when they first met, Su Yan would definitely not have fought with O'Hara at that time. But considering that even the brain is a muscle, and the idiot who only thinks about wreaking havoc everywhere and causing chaos, this kind of character that wants to cut anyone he sees is not a strange thing.

The place where Su Yan woke up happened to be a room.

Although he didn't know what this room was used for before, Su Yan had already seen a lot of such vacant rooms when he was on the first floor, so he didn't feel any surprise. The only thing that made him feel lucky was that the door to the room was not destroyed, so he didn't have to think of any other way to get out of here, although if he had to say bad news, it was probably that he didn't have a map of the fourth layer of the ruins.

Push open the door, and there is no difference between the corridor and the first floor.

But Su Yan sensed it carefully, and then a surprised look quickly appeared on his face.

Contrary to what he had guessed, there was no trace of any monsters on the fourth floor, and everything was incredibly clean.

With a little doubt, Su Yan left the room quickly.

He couldn't be sure that O'Hara was in this situation, and when he used his perception to penetrate the ruins to explore the other side, he didn't find any trace of O'Hara. And this discovery made Su Yan understand that O'Hara was likely to wake up faster than him, but for some reason, the demon king did not choose to come to him for trouble, but left the place where he was before.

Su Yan didn't think that there was anything else in this ruin that could make that demon king feel afraid.

So, the rest of the answer is already obvious.

In this ruin, or on the fourth level of the ruins, there was something that was more important to O'Hara than him. And apparently, even O'Hara didn't know that this thing existed in the first place, which is why it appeared on the second level. And now, because of the collapse and damage it caused, O'Hara found the thing, so its first reaction was naturally to choose to recycle it.

Instead of continuing to entangle with Su Yan here.

After figuring out this, Su Yan's heart only hesitated slightly for two seconds before he made a decision.

Discerning the source of the sulfur smell from the air, Su Yan followed the smell quickly.

As he approached, the sulfurous aura began to grow stronger and stronger, even to the point of substance visible to the naked eye.

The surrounding air was filled with a grayish-yellow mist.

That's a sulfur miasma.

It has a very strong poison, and if an ordinary person approaches, it will only kill in three seconds. If a person with sufficient physical strength but insufficient mental will enters such an area, he will become a demon puppet - a demonic creature that has lost its mind and knows only about killing and destroying.

The most common place for brimstone miasma is around the River of Purgatory, which is the favorite place of all demons.

While recalling the introduction of demons in "Eternity", Su Yan walked quickly to a closed door.

The grayish-yellow smoke wafted out of this gate.

After a slight pause, Su Yan directly pushed open the door.

He wondered what was behind the door, and why there was a sulfur miasma that was said to only appear around the River of Purgatory.

As the heavy door was completely pushed open, a sudden strong wind suddenly blew up, blowing away all the sulfur miasma.

What caught Su Yan's eye was O'Hara's huge figure soaking in a huge pit full of magma.

There is no doubt that the crater that constantly emits a red-red liquid like magma is the water of the Inferno River, which is unique to the Abyssal Purgatory, and the demons love it because no matter what kind of injuries they have, they can recover from it. And in addition to this, the waters of the River of Purgatory have the unique ability to catalyze, evolve, and strengthen everything related to demons.

And when he saw O'Hara actually in this river of purgatory, Su Yan had already understood even how stupid he was.

The previous trampling, and when O'Hara fell here afterwards, it was not as unscathed as Su Yan guessed!

Without the slightest hesitation, Su Yan suddenly bullied up.

The long sword in his hand bloomed with an astonishing cold light!
