The cave was quiet, and Yun Meng didn't notice any abnormal breath, nor did he smell anything. She continued to walk down the largest hole, and as she walked the ground began to slope downhill, as if going downhill, and after more than half an hour, she entered a large round hole.

After walking further and further down for two or three hours, Yunmeng walked around and around in this colluded underground cave passage, but still did not find anything unusual. Until she came to the position of a fault, there was no road in front of her, there was a cliff in front, and there was an underground river more than ten meters below. The river is still very large, and the water is not shallow.

After walking here, Yun Meng hid a different aura, which came from the river below. She crouched on the shore and looked down closely, from her colorless vision. It was supposed to be clear and gray water, but it was black.

Why is the river black? Is it because there's something wrong with the river? That's why the underground orangutans run out?

Yun Meng stared at the river for a while, thinking about the relationship. She walked through the holes for three hours, but she didn't find anything out of the ordinary. There was only one breath coming out that she couldn't tell, and she couldn't even judge the attributes of this breath.

Looking left and right, there are vertical cliffs on both sides of the river, and there is no place to stand. She couldn't find a place to stay, so she had to use her claws to pick at the protrusions on the cliff and slowly climb down to get a closer look at the river.

She wouldn't have jumped into the river anyway.

Fortunately, after becoming a zombie, her body is very flexible, and she often does things like climbing walls and trees.

Easily climbed down the cliff, and when he approached the water, Yun Meng picked one hand on the rock wall, and turned the other hand to touch the water. Then she took a little water in one hand and put it under her nose and smelled it, and immediately smelled a very pungent smell.

"Hmm!" Yun Meng immediately shook his hand and shook off the water in his hand as soon as he smelled this smell, and then climbed up with a brush.

Something was really wrong in the river, and the smell of the water was so pungent. And there is no sign of biological activity in the water.

But just because of this, it shouldn't all run out of the cave, right?Yun Meng frowned in confusion.

After she climbed up, she looked left and right for a long time, and there was nothing abnormal except for the abnormal water of the river. She turned around and began to walk out.

Out of the hole, she jumped onto the roof of a building and whistled.

Soon, several figures appeared in front of her.

"You guys stay here, I'll go back to the base. Yun Meng said to the few zombies in front of him.

Standing in front of Yun Meng were several fifth-level zombie leaders, and they nodded at Yun Meng.

Yun Meng turned around and swept towards the training station not far away, found a car and sat back to the base.

After returning to the base, she immediately went to the No. 1 base to find Yuan Tianxing.

Yuan Tianxing was reading the official document in the office, and someone knocked on the door: "Deputy leader." ”

He looked up and saw Li Zheng standing at the door and said, "Yunmeng is back." ”

Then a fourteen or fifteen-year-old girl with short hair walked in through the door.

Yuan Tianxing was slightly stunned when he saw her, and asked, "What's wrong? Why did you come back at this time? Or is there something wrong over there?"

Look at the time, it's more than eleven o'clock in the evening, almost twelve o'clock.

Although Lin Qiao said before leaving that those underground creatures didn't have to worry about it for the time being, Yuan Tianxing didn't completely let down his guard over there. Now when I saw Yun Meng come back and came to him directly, I subconsciously guessed that there should be something abnormal about those things.

But Yun Meng came back by herself, which means that the situation over there doesn't seem to need her to stand up, and it shouldn't be very serious.

Yun Meng walked into his office, sat down on the sofa and said to him, "There is indeed some condition, but the main reason does not seem to be those underground orangutans. ”

Yuan Tianxing sorted out the documents in his hand slightly, and then stood up and walked to the single sofa next to Yunmeng's sofa and sat down. "You're saying there's a situation, but it's not with the underground creatures?"

Yun Meng said: "Those things suddenly ran out at noon yesterday. Then after a night they didn't go back today, and now they went hunting in the other direction. I took the opportunity to go in and investigate, and found that there was an underground river deep in their hole. There is a strange smell in the river, which is pungent to us, but I don't know if it has any other effect on you living people. But I guess those underground orangutans should have smelled the breath of the water and ran out. ”

Yuan Tianxing listened to her words quietly, and then asked, "How do you know that there is a problem in this water? Have you ever gone down before?"

Yun Meng shook his head: "No, today is the first time to go down." ”

Yuan Tianxing thought for a while and asked her, "Could that be ...... What is the water like that? It may be a little abnormal to you, but it may have no effect on the creatures underground. Is there anything unusual about other places?"

Yun Meng thought carefully about the scene he saw in the cave and shook his head: "No, it's just that those rivers make me instinctively feel abnormal." Other than that, there's nothing strange in the cave. ”

"Didn't those things come towards our base?" Yuan Tianxing suddenly thought of the last time those underground orangutans wanted to attack the base, and asked her with some concern.

"No, they went in the other direction. Rest assured, the chief's words are true. Thinking of the large group of underground orangutans jumping more than ten meters high in the direction of the zoo, Yun Meng shook his head and said.

Then she stood up, "Okay, I'm just coming back to tell you about it." If there's anything else, I'll send someone back to talk to you. ”

Saying that, she waved her hand at Yuan Tianxing and walked away cleanly.

Yuan Tianxing looked at her back as she left, sat in place and frowned.

Although the underground orangutans didn't come out to their base this time, they were so afraid of the sun that they had to run out. It seems that there is something in the underground cavern that scares them.

But from what Yun Meng said, although the situation that she said that there was a problem with the water could not be ruled out, it could also be something else.

Does water alone make them feel fear? It doesn't make sense......

Or is there something in the water? Or is there some danger signal?
