Su Yan carefully searched among the rocks, but unfortunately it may have been too late, and there was no human figure here, but judging from the remaining traces, it should have been a battle after the collapse.

Even the equipment and storage kits on those corpses were taken away.

However, Momiji's body was not found nearby, and it is unknown whether she escaped or was caught.

Su Yan couldn't help but feel gloomy, it was impossible to save people from that demon swordsman, if he could find that black iron and stone room, there would still be a chance, after all, he had just gotten a lot of good things from that Yang Yuanyi, maybe he could let that statue strike again.

Su Yan began to dig forward without stopping, but it was indeed too difficult to find a hidden stone chamber underground.

After spending nearly a day, Su Yan found that he couldn't tell the method at all in the underground.

"Do you want to do things with your own heart like Lu Dao did last time, and I don't know if Lu Dao's luck will continue to work in this kind of thing......" Su Yan frowned, remembering the scene of digging the treasure of the Buddha Gate last time, he closed his eyes and began to dig in one direction at will.

Unexpectedly, when the [Excavation Master] skill ended this time, Su Yan's body suddenly froze, and then he felt as if he was falling down.

"This ...... That's too bad! Who dug a mine right down here! ”

Originally, I thought it would be a shaft that was not deep, but after falling for a full minute, there was still no sign of landing, and Su Yan's face had turned pale. In horror, he hurriedly switched back to his Dark Daoist profession, and then turned on the floating skill of Buyun Boots.

When the time for that floating flight was about to run out, Su Yan finally saw the ground below.

However, his mood was difficult to get better, and he didn't know how deep the road had fallen, and with his low-level miner's digging ability, it was estimated that he would have to dig for more than ten years before he had a chance to climb back to the ground.

Standing at the bottom of this unfamiliar shaft, Su Yan looked around nervously, perhaps because it was in the extremely deep underground, this place was not affected by the collapse of the mine above, and still maintained its original appearance, but when he checked the surrounding cave walls, he couldn't help frowning. It is made entirely of granite. There is no black iron ore at all.

In other words, this place should no longer belong to the mine, but to his surprise, there seemed to be a more familiar aura coming from ahead.

Su Yan cautiously explored forward, and soon found two familiar figures. It was the 'senior sister' who had never been seen and the black-bellied corpse king.

"Senior sister......" Su Yan ran over in surprise.

A stiff smile immediately appeared on the pale face of the 'senior sister'. And the corpse king also learned to squeeze out a trace of a mad smile very reluctantly.

"Why are you here? I thought you were out of the mine. ”

He led the way...... Come here......" 'Senior Sister' pointed to the corpse king next to him.

"What is this place?" Su Yan looked ahead. There seemed to be a long cavern there, and the smell coming from the darkness seemed familiar, yet dangerous. Immediately, I couldn't help frowning.

"Good...... Great place! "This time it was the corpse king who spoke.

Su Yan couldn't help but be surprised, he didn't expect this corpse king's intellectual progress to be so rapid, he hadn't seen him for a few days, and he could already communicate in human language.

However, with the 'senior sister' by her side, Su Yan was a little relieved, although her relationship with herself was very independent, but it was much more reliable than the fox demon pet, and judging from the level of the mine zombies above, the monsters here should not be very perverted.

In the end, Su Yan took the 'senior sister' and the corpse king to continue to go forward, but the corpse king seemed to be extremely familiar with this, and he directly pointed out the method when he encountered a fork in the road along the way.

After advancing in the darkness for more than half an hour, I don't know if I had reached the depths of the earth, and what appeared in front of Su Yan was a closed stone door, and there was a tombstone next to that door.

It looks more like an underground tomb!

"What the hell is this?" Su Yan couldn't help but turn his head to look at the corpse king.

"Enter...... Go in......" The corpse king was extremely excited, pointing at the stone gate.

Su Yan didn't dare to enter rashly, and it was too troublesome to communicate with this corpse king who had just learned to speak, so he had to turn to look at the tombstone.

However, he only glanced at it and couldn't help but be dumbfounded, he was already familiar with the text content on it!

"Yu is willing to fall into the darkness to cultivate the Cave Abyss Sutra in order to avenge his great revenge, although he has achieved a little success, he is not tolerated by the world......"

This is clearly the content of that zombie diary!

Could it be that this tomb in front of me is left by the old zombie road...... But if the zombie is buried here, then who are the two zombies he killed in the first place?

Su Yan walked in front of the stone gate in surprise, and a strange black light immediately enveloped him.

Su Yan was shocked, but seeing that there was nothing abnormal in his body, he breathed a sigh of relief and reached out to push the stone door.

The stone door that seemed to weigh more than a thousand catties was opened casually, and even Su Yan felt that the stone door had opened by itself.

Behind the stone gate is a long passage, but the walls on both sides are made entirely of skulls, which seems to be very much in line with the identity of the zombie veteran.

However, when Su Yan walked out of the passage, the front suddenly became clear.

However, his gaze was instantly glazed, and in front of him was a space similar to an underground hall, the size of a football field, and in it stood rows and rows of zombies, looking like a group of terracotta warriors and horses used for burial.

However, judging from the hideous appearance of those zombies, these should all be corpse king-level existences, among which the tallest corpse king is more than ten meters high, wearing heavy armor, and the weapon in his hand is a hideous giant axe more than ten meters long, which is estimated to be used only when attacking the city.

Su Yan casually used insight to look at the two zombies in front of him:

Corpse King

Grade: 87

Second-order bronze corpse

Attack: Unknown

Defense: Unknown

……

And the other one is as high as level 91!

Su Yan swallowed with some difficulty, could these be the many corpse kings that the zombie old dao had refined back then.

The 'Senior Sister' and the Corpse King who followed him in also seemed to be equally shocked, and they didn't dare to move at all when they stood behind him.

Looking at these hundreds of corpse kings of different shapes, Su Yan finally understood the power of the zombie old way back then.

Controlling these hundreds of terrifying corpse kings is equivalent to leading hundreds of eighty or ninety level players in battle, and it is the kind that is not afraid of death.

In comparison, the zombie army that he used to be proud of seemed particularly childish and ridiculous in front of these guys, and even the dark wizard could only be regarded as a schoolboy.

Maybe these are the true inheritances of the old zombie way...... (To be continued......)
