Anji Mountain is not a high mountain, and some temperate coniferous pines stand on the slopes.

The plane stopped in a col in Anji Mountain, and from a distance, it was absolutely thought that it was just an extra rock.

As a professional agent, Cao Yanan is much more professional than others, she just went out for a turn, and she had already drawn down the terrain map of the periphery.

At this time, everyone was listening to the explanation around the picture she had drawn.

"This is the Aris Reservoir, this is the Aris River, and the water of the Aris River does not flow west to the sea, but is stored in the Aris Reservoir, so the Aris Reservoir is very large. But the river keeps coming down, and the water level of the reservoir never rises, why. ”

"Look at the position." Cao Yanan drew a circle in the southeast corner of the reservoir.

"This is the reservoir drainage hole, and in the dry season this place is exposed to the water, and you can see that there is a huge hole here, and it is more than 1,000 meters deep vertically, and no one will come close to look for death. During the rainy season, the reservoir is swollen, but the water level remains at this level, which means that the drainage hole leaks all the water. ”

"Does this have anything to do with District 51?" Zhang Zhi said suspiciously, a few people went out to explore for a day, and the nearby maps were clearly drawn, and they didn't see any District 51, but they heard Cao Yanan talk about the drainage system of the reservoir here.

"It has a relationship, the entrance and exit of District 51, when I came this time, I found that it was gone, it must have been sealed, and we couldn't detect it if it changed places. But the reason why I was able to escape last time was because it was the dry season, and I escaped into the underground river, which was connected to the drainage hole, and I climbed more than a thousand meters with my climbing claws before I came out of it. ”

"I see, doesn't that mean that this place can be regarded as another entrance and exit of District 51?" Zhang Zhi suddenly thought.

"Yes, but it wasn't taken seriously here before, and now I don't know if it can be passed."

Cao Yanan said worriedly, but Zhang Zhi said: "It's okay, even if it's a strong attack, we are not afraid of anyone in the world." ”

"The thing is, it's the rainy season!"

Yu Wenhao was silent, and interjected at this time, which made the scene cold.

Tens or hundreds of tons of water poured into the huge drainage hole every second, and then fell more than a thousand meters into a free fall, and if it was fought head-on, no one's body would be able to resist such an impact.

Even if you fall from a building more than 1,000 meters, you will fall into a meatloaf.

The other people's expressions were stunned, and they didn't dare to imagine that even Zhang Zhi didn't dare to do such a thing.

Cao Yanan said: "It's okay, dozens of tons of water go down every second, not on stones, but into the underground river." If we jump, we will fall into the water, and I think everyone here should have no problem jumping into the water from a distance of more than 1,000 meters. ”

"Theoretically, there is no problem, but Lao Tao thinks that everything must be prepared for the worst. If things don't work out, we have to go back, and it's absolutely impossible to go through this passage, even if it's a dragon, I don't think it's capable of rushing up through this drainage hole. ”

It was Ou Wanning who spoke, this veteran Taoist, and it was the first time he had expressed his opinion.

Everyone turned their eyes to Zhang Zhi, and now, it was time for him to make up his mind.

Zhang Zhi thought for a moment and said: "It's all here, do it!" In the underground, there is no place for large weapons, and the strength of our people is not weak anywhere. However, if someone doesn't want to participate, they can quit now, even if it's just me, I'll do it. ”

Don't look at Zhang Zhi's arrogant words, but the people present are all human spirits, but no one was infected by him, and after a few seconds of silence, Yu Wenhao was the first to speak: "I'll join!" ”

"I'm joining!" Cao Yanan and Yu Wenhao are both soldiers, and this is a national task, so it is impossible for them to retreat from the battle.

"If you come, you will be safe, count me in." Monk Xuanbei clasped his hands together and said.

Zhang Zhi was stunned for a moment, he said that if he could quit, he just wanted to give Xuan Bei a step down, so that he could take the opportunity not to participate in this matter and end up with all right, but he didn't expect him to volunteer.

Ou Wanning saw that everyone had expressed their positions, and only himself and his nephew Li Qingfeng were left, and their faces were a little unsightly.

"Well, since you're here, let's try it too." He is a man who wants to save face, and for the sake of face, he dares to take such a risk.

Ou Wanning participated, and Li Qingfeng was naturally out of the question, so the six-person team acted in unison again.

Xue Beichen and Du Yumin didn't speak from beginning to end, they just picked up people, and when they got here, everything was handed over to the temporary captain Zhang Zhi.

"Okay, in that case, let's prepare now, and we'll leave in ten minutes." Zhang Zhidao.

"Good!"

Ten minutes later, the six people gathered under the plane, Zhang Zhi put on his new armor, the helmet was tucked under his armpit, and the others were each covered with various weapons, and it could be seen that they were not ordinary.

Everyone looked at Zhang Zhi in amazement, he only had his head and feet now, and a big sword was exposed, and the part of his body was transparent, and if he didn't look carefully, he couldn't even see it.

"Let's go!"

Zhang Zhi didn't expect that even Cao Yanan, a great hero, had not obtained such armor, and it seemed that this time the military region had invested heavily in himself.

"Don't worry, Lao Yan, I will make your investment worthwhile!"

As the saying goes, taking other people's hands short and eating other people's soft mouths, Zhang Zhi is obviously being tricked, and he himself is willing to be tricked like this.

Thinking of this, he proudly put on his helmet, and at first glance, everyone only saw him walking in front of him with a pair of leather shoes, and a big sword dangling in the air out of thin air, the scene was extremely weird.

The six of them soon arrived at the lake, and their hearing was fully open, and they were sure that there were no living people within a few kilometers, but there were some scattered zombies on the edge of the lake, which was a natural barrier.

The Aris Reservoir is very large, with a radius of more than 10 square kilometers, the water is clear and deep, and there are drainage holes like black holes, even in normal times, no one comes here to move, let alone today.

Finding a place where there were no zombies, the six people quietly dived into the water, dived to the drainage hole, and surfaced from time to time to ventilate.

Their current physical fitness has no problem diving in the water for about ten minutes, and soon, the six of them have reached the vicinity of the drainage hole, and the strong suction makes the six of them almost unable to grasp their bodies.

"It's normal, let's go!"

Zhang Zhi felt it slightly, there was no movement on the shore, so he ordered.

None of the others dared to move forward directly, Zhang Zhi had to swim forward first, but when he reached the vicinity of the drainage hole, the huge whirlpool was not at all something that people floating in the water could resist, and everyone held their breath and was quickly sucked into the whirlpool.

Everyone has never felt this way in their lives, this is like duckweed without roots, life is not controlled by itself at all, the body is already falling, but the soul does not seem to have fallen.

The further down he went, the more obvious this feeling became, and even Zhang Zhi felt the fear of not having anything to rely on.

The speed of descent is getting faster and faster, and at this time everyone seems to have turned into a drop of water, and the side is getting darker and darker, and the faint light above the head is getting farther and farther away.

At a certain moment, as if encountering resistance, the rumbling sound around him disappeared, and the soul quickly returned to the body, Zhang Zhi looked out through the helmet, and sure enough, he was in a huge deep water tan. Although it was pitch black under the drainage hole, in just a few seconds, Zhang Zhi could vaguely see something.

In the past few days, there are more scientific talents around Zhang Zhi, and sometimes he asks some questions.

There must be light so that the human eye can see objects.

Light is produced by the movement of photons, and any matter is in the microscopic world all the time for internal energy movement, this movement, all the time to produce photons, but when there is no other light source illumination, the number of photons is very small, so that our human eyes can not feel it at all.

When a person's mental power reaches a certain level, the photons that can be felt are beyond the scope of ordinary people, which is why now Zhang Zhizhi has night vision, and he can feel objects in an environment where there is less photon movement.

Others could, but not as exaggerated. He was now in an underground environment, and he had the sense of déjà vu in the moonlight.

He saw other people's bodies, and other people didn't start moving as quickly as he did, but they were still drifting with the flow, and after waiting for seven or eight seconds, someone was relieved from the chaos, and the first one to recover was the monk Xuanbei.

"Three points of spirit, how can this be?" Zhang Zhi couldn't believe it.
