Cheng Hao's transformation was a bit too exaggerated, but Bai Chi didn't want to linger in front of these two bone mountains now, so he hurriedly winked at the wretched man and Shen Li.

The wretched man cursed "Fuck" and followed him. Shen Li also glanced at Bai Chi and followed the wretched man. Bai Chi breathed a sigh of relief when he saw both of them leaving, but when he turned around and was about to leave, with the help of There was a faint light in front of him, and Bai Chi suddenly saw a green palm exposed under the pile of bones.

Now Bai Chi doesn't want to know who the owner of this palm is. Cheng Hao must have seen it just now and knew who was holding it down, otherwise he wouldn't have left without reason, let alone said such words.

Since Cheng Hao doesn't want a few people to know, he must have his own reasons. For Cheng Hao, Bai Chi has always measured it from Liu Wei's point of view. Bai Chi will not ask too many things, nor will he force anyone to tell his secrets. .

The wretched man and Shen Li walked closely, with Bai Chi following at the end. His mind began to have random thoughts again, but Cheng Hao just kept his head down and walked away like a normal person.

When he came to the corpse of the other black-haired monster, Bai Chi realized that the four people had already walked into another cave.

Cheng Hao in front stopped again. Every time he encountered danger or strange things, Cheng Hao acted like this. At this time, Bai Chi took out his pistol and after loading it, he found that there was only one bullet left...

Cheng Hao neither spoke nor made any movements in front, he just stood upright. The wretched man couldn't hold himself back and took out his pistol, and asked Cheng Hao:

"What did you see? Don't be so surprised again, okay?"

Cheng Hao turned around and made a silent gesture to Bai Chi and the others. Bai Chi walked over with a pistol in his hand, stood beside Cheng Hao, and vaguely heard the sound of running water.

Bai Chi was not sure whether it was the sound of the Yellow River water outside the cave, or whether there was an underground stream inside the cave. In short, the sound was not very obvious, but it could be caught.

The wretched man was stunned for a moment and noticed the sound of running water. He nodded to Shen Li and walked to Bai Chi and asked, "Why is there an underground river here?"

Bai Chi looked back at the wretched man and asked softly:

"Can you tell it's coming from inside the cave?"

The wretched man nodded and said:

"Boss, although my ears are not good, I can distinguish the sound at once. If there is really an underground river inside, then it is likely to be connected with the Yellow River!"

Bai Chi thought about it and made sense. Behind the four people was the Yellow River, and if there was an undercurrent at such a short distance, it was most likely that water from the Yellow River seeped into the cave, forming an undercurrent.

But when I thought about it again, something felt wrong about Baichi. This cave spread too deep. How could the river water seep into this place? Moreover, there was not too much moisture on the stone wall along the way, and there was not even a sign of moisture.

Shen Li thought for a while and asked:

"Is there any danger ahead? There's no point in guessing now. Won't it be clear when we get there?"

Bai Chi laughed after hearing this. His thinking was too rigorous. Every time he encountered something, he had to figure it out first. Compared with Shen Li, this way of thinking was a bit petty.

The wretched man smiled at Bai Chi, and then asked Shen Li: "Does your head still hurt now?"

Shen Li blushed and replied:

"It doesn't hurt anymore, let's go in!"

After taking a few steps, Cheng Hao in front stopped for some unknown reason. The wretched man shouted in displeasure:

"Why don't you leave again? Are you uncomfortable holding in your pee?"

Bai Chi made a 'poof' sound and cursed:

"Can you stop being so tacky and look at Shen Li still here!"

The reason why Bai Chi called out Shen Li's name at this time was to tell her that I, Bai Chi, no longer need you to use your identity as a policeman to talk to me about things. But Shen Li didn't understand the meaning of Bai Chi's words. He kept staring at the wretched man.

The wretched man did not dare to say irritating words to Cheng Hao, and finally pointed his head at Bai Chi, snorting as if to vent his anger. Bai Chi gave a silent bitter smile, and Cheng Hao turned around and asked:

"Do you smell anything?"

Bai Chi listened carefully, put his head forward and smelled it, and felt that there was no smell. The wretched man thought for a while and said doubtfully: "Why do I smell the smell of blood?"

After smelling it carefully, Bai Chi suddenly felt that it seemed to be a faint smell of blood. He looked sideways at the wretched man and asked, "Are you sure this smell is the smell of blood?"

The wretched man nodded and said: "After smelling it for so long, I still smell it wrong? But this smell is a bit disturbing, and it seems that there is more than a little blood!"

When Bai Chi heard this, he immediately thought of the tunnel that Liu Wei had blasted out of the human and animal pit in Ziying's Tomb. The smell now seemed to be the same as the fishy smell in that tunnel.

Bai Chi frowned and looked at the darkness ahead, involuntarily sketching a purgatory-like scene in his mind.

Cheng Hao had already taken a few steps without knowing it. Bai Chi nodded to the wretched man and hurriedly followed him.

Ever since I went to Ziying's Tomb without thinking, I've walked a lot in places like the cave, but this is the first time I've been able to walk as hard as I did today.

At this time, the wretched man touched the cave wall with his hand, frowned and thought for a while, and said:

"Why does this look like it's used for drainage? Look at the lines!"

As he said that, he took the flashlight from Shen Li's hand and shined it. Bai Chi took a look and found that there were indeed traces of water settling on the cave wall after it flowed.

But after a while, his mind turned around and he stared straight at the wretched man. The wretched man was so frightened by Bai Chi's gaze that he said:

"Boss, why are you looking at me?"

Bai Chi thought for a while and said:

"You said if this is for drainage, then why wasn't the bone mountain in the stone hall washed away by the water?"

The wretched man suddenly slapped his head, looked at Bai Chi, his eyes shone, and said:

"Boss, don't tell me this is not for drainage?"

Bai Chi shook his head and explained:

"I don't know. Look at the water level marks here. If it's not used for drainage, what is it used for?"

Shen Li interrupted at this time:

"I feel that when this cave was built, the water in the Yellow River was not so high, and these water traces came up at the end!"

When Baichi heard this, he was enlightened, and a certain possibility suddenly occurred to him. Shen Li meant that this place might be a place suitable for people to live or work. At that time, the water of the Yellow River might only be as high as it is now, and when the water level When it came up, people who originally lived here were leaving one after another.

Now I am afraid that this is the only theory that is feasible, and considering the skeletons outside the cave, it is very likely that they did not dare to go into the water and starved to death.

This guess is indeed a bit crazy, but after all, nothing cruel happened. However, the two bone mountains in the stone hall have always been taboo to Bai Chi, especially the green hand pressed underneath.

After walking for three or four minutes, the sound of running water became louder and louder, and at the same time, a pungent smell of blood came over me.

At this time, Bai Chi's heart began to tighten. The voice in front of him seemed familiar, but he couldn't remember it.

Cheng Hao scanned it in front with his flashlight, and the four of them were stunned. There was indeed a small river in front of them, but what made people's heart palpitate was that the water in the river was not water, but a collection of blood.

The moment Shen Li saw the wretched man, she vomited. Now that they were so close, the nauseating smell also made Bai Chi's stomach churn. This smell was too strong, even worse than when she was in Ziying's tomb. It still stinks when you walk through the corridor filled with corpses.

Finally, the wretched man couldn't help but vomited too. At this time, Bai Chi and Cheng Hao didn't feel anything at all. They seemed to be used to the smell.

After slowly getting used to it, Shen Li hurriedly took out a mask from her bag and handed one to the wretched man. After wearing it, she still felt that she could block the smell, but after all, she had measures and could barely numb herself.

In the blood river in front of them, blood was flowing continuously from the upper reaches. The four people were speechless for a long time, not daring to imagine what kind of existence the upper reaches could transport such a large amount of blood.

This scene is incredible. If there was a blood storage pool over there, it would have dried up long ago after so long. However, the blood seems to be very fresh, as if it was just left from the body.

Cheng Hao was very bold. He leaned down and touched a little with his hand, put it in front of his nose and smelled it carefully. His face gradually improved, and he looked at Bai Chi and said:

"This is not human blood!"

Bai Chi had no way not to believe Cheng Hao's statement. Even if it was really human blood, Bai Chi had to convince himself that it was animal blood. After all, there was too much blood. If human blood was to be used, how many people would have to be killed?

Cheng Hao scanned left and right with his flashlight and saw a winding path on the right. He nodded to Baichi and planned to go that way. He wanted to go upstream.

At this time, the wretched man tapped Bai Chi's back. Bai Chi looked back and saw that the wretched man's face was a little pale, maybe because he didn't want to go. Bai Chi helplessly shrugged at the wretched man, and Chong Hao rolled his eyes and followed.

Just before the wretched man moved, a lot of bubbles suddenly emerged from the blood river. Bai Chi hurriedly picked up the pistol, but when he thought about it, there was only one bullet left, and he quickly retreated to the side of the wretched man. .

Cheng Hao also noticed something strange in the blood river, and looked very unhappy. He swept his flashlight over there, and saw that the blood river was constantly "gurgling" as if boiling water was boiling.

Bai Chi sighed, there shouldn't be something similar to the black-haired monster here, right?

The wretched man trembled and cursed: "Holy crap, are there really fish in here?"

Bai Chi was too lazy to talk to the wretched man. Cheng Hao also withdrew at this time, holding the short knife across his chest.

"Damn it, no matter what it is, if it dares to come out, it will be killed!",

Bai Chi said, but he couldn't help but look at Cheng Hao. As long as his face looked good, there shouldn't be anything scary, but what made Bai Chi scold her was that Cheng Hao's face also turned pale.
