There are four piles of corpses like these hills, probably hundreds of corpses. Xiao Yu has also killed people. In Zhong Kui's memory, he has also seen piles of corpses in the caves of some demons. However, this is the first time he has seen such a scene of hundreds of piles together. It can be seen that these things shocked Xiao Yu.

Xiao Yu looked at the ground here. At this time, the ground here still had its original color, but it turned into a black color, and a bloody smell echoed in the room.

"No wonder there is such a strong blood here." Xiao Yu's ghost floated in the air and looked at the black ground and thought secretly.

After seeing the situation here, Xiao Yu understood why there is so much blood in the Yin Evil Qi, not to mention that the blood here is combined with the resentment and evil energy here, forming this rich blood and energy light.

It is precisely because of this that the ghosts here are much stronger than those outside. But what surprised Xiao Yu was that there were so many corpses here but no ghosts existed, so Xiao Yu was very puzzled.

You should know that this place is also considered an extremely yin place, and it is also the legendary place to raise ghosts, so the ghosts just now existed, and some things should have been blocked here, so that the evil spirit and ghosts here have always existed here. The small hole that Xiao Yu just came in obviously destroyed this place, causing not only the yin energy here to leak out, but the ghosts also ran out.

At this point, a strange phenomenon around this building was formed, so there was nothing strange about hurting a few people here before.

"Gaga..." Suddenly, a strange sharp laugh sounded in the underground space. After hearing this laughter, Xiao Yu was stunned and listened carefully. It turned out that the laughter was coming from the other side of the wall. Xiao Yu's ghost floated in the air and did not feel anything next door, so his expression became serious immediately after hearing this sharp laugh.

"It seems that there are secrets that I don't know here." Looking at the wall, Xiao Yu thought secretly.

After thinking for a while, Xiao Yu shook his hand holding the Demon-Slaying Sword and shook it gently. The Demon-Slaying Sword composed of mysterious patterns turned into the mysterious patterns again and extended to the wall.

"Baopao...Baopao..."

When this mysterious pattern extended into the wall, bursts of firecracker-like bursts suddenly came from the wall, and the wall made of cement also appeared.

It turns out that many jade talismans were built into this wall, but these jade talismans were very simple to make, but they were better than the number.

However, the jade talismans in the wall have been destroyed by Xiao Yu. Therefore, after Xiao Yu heard a sound in the wall, he flashed and disappeared. When he appeared again, he had already reached the other side of the wall.

As soon as Xiao Yu reached the other side of the wall, several black shadows rushed towards Xiao Yu.

"Ghosts devour the world..."

Seeing the ghost rushing over, Xiao Yu shouted softly, his head suddenly became bigger, and the ghosts rushing towards him rushed into his mouth. After all these ghosts rushed in, Xiao Yu closed his mouth and his head slowly returned to normal.

After Xiao Yu's head returned to normal, his stomach slowly bulged, and it was still moving inside. After feeling this situation, Xiao Yu was stunned for a moment, a bitter smile appeared on the corner of his mouth, and he slowly closed his eyes.

After a while, Xiao Yu's belly slowly became smaller. Xiao Yu opened his eyes, opened his mouth and slowly let out a breath. As Xiao Yu exhaled, a mouthful of black mist rushed out of his mouth and gradually dissipated, and the illusory figure of Xiao Yu's ghost gradually condensed a little.

Xiao Yu looked down at his ghostly figure, with a hint of joy on his face. Although he had known that ghost-eating people could help him recover his ghost, his ghosts had not left his body some time ago, and ghosts also had their own homes, and the underworld was their best choice. So even if Xiao Yu's ghosts could recover from their ghosts, he had never eaten them, except for those evil ghosts and ghosts like the kind of ghosts here.

There are also ordinary ghosts here without consciousness. Such lonely souls will dissipate even when they reach the underworld. If they do not enter the underworld, they will soon be assimilated by the pure yin energy in the underworld. Therefore, Xiao Yu has never softened his heart when he is about those ghosts.

"Is the poison gas chamber?" Xiao Yu looked around in this room and saw several corpses hidden on the ground of the room. The corpses all turned blue and black, obviously died of poisoning. The structure of this room reminded him of the biochemical bases of the Luguo country in the anti-Japanese war movies.

Xiao Yu didn't think of these things just now in the house where the corpse was piled up, but when he entered this room and saw the situation here, he immediately thought of these things.

Thinking of this, Xiao Yu's ghost figure flashed again, and when he appeared again, he arrived at another room.

Looking at this room, Xiao Yu's brows became tighter and tighter. This room was obviously like an operating room. In the corner of this room, there was a large iron cage, and there were two corpses in the iron cage.

There are also several ghosts in this room, a few ghosts in white coats and a few ordinary ghosts. However, these ghosts in white coats are very strong, while those ordinary ghosts are all wearing ordinary patches. The old society's double-breasted jacket hid in the corner and shivered.

When Xiao Yu first entered this room, the hunched ghosts in white coats were biting the ghosts squatting in the corner. Every time these ghosts in white coats bite off those ghosts, they would bite off a trace of the yin energy from these ordinary ghosts.

At this time, these ordinary ghosts were already full of holes and extremely weak.

When Xiao Yu came in, these ghosts in white coats floated into the air instantly and looked at Xiao Yu who was floating in the air.

"Who? Why haven't you seen you?" These ghosts in white coats looked at Xiao Yu and asked in a hoarse and sharp voice.

While they were looking at Xiao Yu, Xiao Yu was also looking at them. The strength of these ghosts was obviously much stronger than those outside. Moreover, the bodies of these ghosts had impure yin energy. Although this yin energy was mixed, it also made them much stronger. These yin energy were obviously caused by their devouring of these ordinary ghosts.

Seeing this situation, Xiao Yu's eyes turned cold and his head grew rapidly. With a slight sucking, an invisible and powerful suction force sucked at the ghosts in white coats.

"Aoao..." After seeing Xiao Yu's head grow bigger, these ghosts didn't know what was going on. A trembling aura suddenly appeared in the depths of their souls. Although they didn't know where the aura came from, Xiao Yu was definitely the source, so these ghost monsters in white coats roared and rushed towards the wall next to them.

When Xiao Yu saw them running, he did not look anxious, but instead took a breath again.

When Xiao Yu sucked out this breath, the ghosts who had already run to the wall stopped immediately. Not only that, their bodies also flew backwards towards Xiao Yu's huge mouth.

These ghosts in white coats struggled in the air, but no matter how hard they struggled, they could not escape the suction force. They struggled to run out into Xiao Yu's mouth.

Although these ghosts are not weak, they have not reached Xiao Yu's limit yet, so swallowing these ghosts will not have any impact on him, but will further improve his strength.

After Xiao Yu ate these ghosts, his body condensed a little more.

Xiao Yu knew why he saw these ghosts in another room. Although these ghosts were eaten by these ghosts in the Lu Kingdom, it was difficult to digest them, but they should be able to digest them after a long period of polishing. And judging from the arrangement here, there should be experts among the people of Lu Kingdom, and their strength should be quite strong.

But the only thing that surprised Xiao Yu here was why these people in the hukou country died here now. Moreover, Xiao Yu had just seen the corpses of these hukou country ghosts. There was no sign of poisoning on the corpses of these people, so Xiao Yu was very curious about the cause of their death.

Now Xiao Yu's Yinhun's strength has recovered part of it, so he could also vaguely feel the movements in the room.

In Xiao Yu's perception, this underground building is very large, and Xiao Yu is now just a corner. However, Xiao Yu is not sure how big it is, because his perception is not completely. Moreover, in his perception, several powerful fluctuations of Yin Qi came faintly.

Xiao Yu's figure flashed and was about to fly towards another room, suddenly his figure did not appear in another room, but appeared again on the wall of this room, slowly closing his eyes and thinking.

It turned out that when Xiao Yu was heading towards another room, a memory suddenly appeared in Xiao Yu's mind. This memory was not Zhong Kui's memory, but from the memories of the ghosts in white coats he swallowed.

Just now, after Xiao Yu swallowed these ghosts, he did not completely transform the pure Yin energy on these ghosts. Just as he flew to another room, the last trace of things on these ghosts were transformed by him, and the last trace of things included the memories of these ghosts.
