I don't want to solve the case when I'm a little policeman.

Xu Zheng and the others encountered various difficulties on their way forward, such as the varying widths of the peaks, some steep cliffs, and poisonous snakes and beasts. But with the help of modern tools, they did not stop the group from moving forward.

Walking to the open area, the squadron found a black bear's territory on a sunny slope.

The honest and ferocious blind black man just rushed out of his den when he heard the noise. When he saw a group of two-legged beasts dressed in black, he didn't even want to den, and rushed into the dense forest again.

Xu Zheng felt it was a pity that as soon as the black blind man ran away, his bear's paw was gone.

Squadron Mi smiled bitterly and shook his head, "This black blind man must have been injured by poachers. He knows that we humans are not easy to mess with. I will go to his den to see if there is a secret passage."

Squadron Yan also reminded: "We have entered the real virgin forest from here. Please pay more attention, especially those poisonous insects and leeches. If something is wrong, please report it immediately."

"My back is itchy. Is it an infection?"

Before Squadron Yan finished speaking, a young special police officer in the team shouted out, saying that he wanted to reach out and touch his back.

"Don't move, let me take a look." Squadron Yan quickly walked over and lifted up the clothes on his back, only to see a dozen leeches trying to burrow into his body.

This scene directly caused several special police officers nearby to turn their faces to the side.

In response to this situation, Squadron Yan calmly took out a lighter and drew a flame close to the leech. Soon the leech was roasted by the fire, rolled up into a ball and fell down.

After dealing with these leeches, Squadron Yan gave him some water to cleanse him, and once again told him some precautions. He didn't say much else. He had given them a warning before coming here, so they weren't tricked yet.

Originally, when selecting the nine special police officers, the experienced ones were selected first.

But looking at it now, this young man definitely has no experience in the jungle and was shoehorned in with seniority and merit.

Xu Zheng stood in front of the team and looked at the scenery ahead, pretending not to see what was going on behind him. After a minute, Squadron Mi emerged from the bear's den holding his nose.

He took a long breath to calm down and shook his head, "This blind bear's den really stinks. There is no secret passage in it. It seems we have to continue moving forward."

But after climbing over several blade mountains, everyone finally stopped because the blade on the top of the mountain in front of them was too big to go around, and there were cliffs on both sides of the mountain.

Maybe Yuan Qinggang was hiding on the other side of this mountain peak, so after everyone discussed it, they decided to climb to the top of the blade mountain.

There are many types of mountain climbing, but Shennongjia officials do not allow police to use destructive methods to climb mountains, such as driving steel nails into stone walls or using mechanical means such as steel claws.

The Blade Peak looks like rocks, but after hundreds of millions of years of wind and rain, no one can guarantee whether they will be damaged during the climb.

There were originally 36 blades here, but you broke one while climbing and arresting people, and now there are 35 blades. If the scenic spot lets you go, people across the country probably won't agree.

In short, they asked the police not to damage the landscape here.

When Xu Zheng and the others came to Blade Peak, they felt as smooth as a mirror when they touched the stone wall, without any gaps. It would be really difficult for a person to climb it without damaging the stone wall.

Squadron Mi sighed with emotion, "Team Leader Xu, I think we went the wrong way. Yuan Qinggang definitely didn't enter the mountain from here. He should have another way."

Xu Zheng knew this when he came here, but they didn't notice it, so they could only use stupid methods. He waved his hand behind him, "Let's do it, let's hurry up."

When he got out of the way, the group of special police officers behind them took off the baggage on their backs and took out carbon fiber poles as thick as their thumbs to form a detachable U-shaped ladder.

This was specially borrowed from the fire brigade and used to climb the more than 200-meter stone wall in front of me.

The SWAT officers were very quick with their hands and feet. After a while, they reached the top of the blade while assembling it. Then the SWAT officer at the top lowered the ladder to the other side of the blade.

Wait until everyone else has passed, leaving two people at the end to dismantle.

After climbing over the blade mountain, Xu Zheng breathed a long sigh of relief and said to Squadron Mi with a smile: "After all, this thing is more powerful. If one person climbs it hard, let's not say whether it will damage the stone wall.

The danger is great. "

The Mi Squadron has seen the construction of tunnels, signal towers and cable cars. This kind of detachable ladder can only be described as child's play. "Technology is still developing rapidly now."

No matter how difficult the road is, it cannot be difficult for today's human beings.

If that doesn't work, you can also use a helicopter to land with people. "

Before Xu Zheng could say anything else, one of the two special police officers who had scouted the road rushed back with a happy face and said loudly: "Team Leader Xu, there is a stream ahead, and we found a plastic candy on the bank of the stream. bag."

"What? Quick, take me to see it." Xu Zheng urged after hearing this.

When he arrived, the SWAT policeman who stayed at the same place fished out the candy bag from the stream. It was no bigger than a palm, and it looked like it should be the packaging bag of rainbow candy.

There are some floating branches in the middle of this stream, which just block the floating objects flowing down from above. The packaging bag is right in the middle of the floating objects.

Xu Zheng observed for a while along the stream and found that the source of the stream came from a cave about 300 meters ahead. The entrance of the cave was blocked by branches, so it might not be possible to find it if it was far away.

"Brother Mi, look around and see if there are any other clues?"

A special police officer took out a radar detector and wanted to test the depth of the hole. It was not known whether the magnetic field affected the operation or the hole was too shallow. The signal displayed on the screen kept changing.

Xu Zhengze looked at the hole. There was no problem for an adult to get in, and the top of the hole was very smooth. It was obviously the result of friction from many people passing by.

There are also branches blocking the entrance of the cave. Although they are leaning branches of a tree, the tree is not big.

Much like human behavior.

But there is no trace of anyone coming here recently.

This is the depth of the 36 Blade Peaks, and it is also where Xu Zheng and the others suspect Yuan Qinggang is hiding, so they must send someone to check this cave entrance.

Soon, the news of the return of Mi Squadron interrupted Xu Zheng's thinking, "There are no other clues downstream, but I can conclude that Yuan Qinggang did not come out of this hole."

If it doesn't come out of this cave, then there is another way.

Xu Zheng looked at the time and saw that it was already two o'clock in the afternoon. He made a quick decision, "Two special police officers will stay and guard, and the others will follow me into the cave.

If we didn't come back before five o'clock, the two people who stayed behind would send out flares and warning fog at five o'clock in the afternoon, and let the helicopters that came over drop camping equipment for us. "

After arranging the planned plan, Xu Zheng took out the safety helmet and put it on his head, turned on the high-power flashlight on it, and took the lead in wading into the water hole.

When I first entered the narrow cave, I crawled against the water for dozens of steps, and suddenly I realized that this was a cave as tall as one person.

Unfortunately, there are no signs of human activity here, only the droppings and shriveled corpses of animals.

There are no bats on the roof of the cave, so it seems this is not their nest.

Further inside, the road becomes much narrower, but passable.

After walking for another ten minutes, we finally arrived at a large cave.

Xu Zheng took a flashlight and looked around. The area was more than sixty square meters. What surprised him was that there seemed to be signs of human activity here.

Because there are several fire pits piled with stones, and there seem to be residual ashes.

A few lights illuminated the cave, making it as bright as day.

There is actually a pool here. The strange thing is that there is no water flowing into it, but the pool is still flowing outward.

"Team Leader Xu, look, there is a bed of weeds and dry branches here. It looks like it has been there for a long time and is not rotten."

Xu Zheng waved his hand and did not go over. He had just looked around and saw clearly that there was no other way here except the way they came.

But there were signs of human activity. If Yuan Qinggang hid here and lived here for 15 years, he would have left more traces, but it is obvious that he did not live here for a long time.

What makes Xu Zheng even more disappointed is that there are no treasures here.

Could it be that they were looking in the wrong place?

Xu Zheng reached out and touched the pool water. It was very cold. It was definitely not underground water, because the entrance to the cave was about two thousand meters above sea level. He had only walked ten minutes after entering the cave.

Not enough to get to the bottom of the mountain.

But if it’s a deep mountain spring, where is the source?

Xu Zheng took out a stone from the fire pit and threw it into the pool, but he only heard the sound. With the water splashing everywhere, he couldn't see where the stone sank.

Other special police officers, including Mi and Yan, searched the surrounding area and found no other intersections or secret doors. They also gathered around the waterhole and waited for Xu Zheng to issue new orders.

Xu Zheng took off his backpack and threw down his helmet. "Brothers, I suspect there are other caves under this pool. I want to go down and have a look."

"No, this is too dangerous. Should we go down?"

This time, not to mention Mi and Yan, even the special police officers present had objections, for various reasons.

Xu Zheng waved his hands and rejected all their suggestions. It was not that he wanted to take credit, but that he believed that his ability was better than these special police officers. "Let's do this. Another special police officer will come and we will dive at the same time.

By the way, tie the rope to us. If there is a special situation, I will pull the rope to remind you. "

Mi and Yan knew that Xu Zheng had made up his mind. They couldn't refute it, so they nodded and started to prepare.

A deputy captain led by the SWAT team came out. He was about 35 years old and volunteered, "Team Leader Xu, I'm with you. My part-time job is a diving instructor."

"That's just right, Captain Wang, you came with your pistol. Don't forget to bring it with you when you go into the water." Xu Zheng instructed.

Recreational diving can dive to a maximum depth of 40 meters, but without oxygen, it can only dive for about five minutes. Therefore, Xu Zheng and the deputy team member set the time to go down to five minutes.

When five minutes are up, no matter what the result is, Mi Squadron and the others will immediately tighten the rope.

Soon Xu Zheng and the two were ready. In order to prevent accidents, they each brought two empty mineral water bottles tied to their bodies. This was one of the means for them to save their lives.

Before entering the water, they each picked up a big stone.

Xu Zheng took a deep breath and jumped into the pool first. He felt the water was biting to the bone. After taking a moment to get used to it, he put his head down and began to dive.

Through the waterproof flashlight bound to his wrist and the crystal clear water in the spring, he could see clearly what was going on in the water.

What he didn't expect was that there were fish in the clear water pool, but the fish was as white as snow, so white that you could clearly see the internal organs inside, and it was not big, as long as a palm.

But now he was busy diving and didn't have time to pay attention. He looked around and found that the pool was in the shape of a gourd mouth, with a larger area below.

As he went down, Xu Zheng felt the pressure in his chest getting stronger. He exhaled a little air to release the carbon dioxide in his body and relieve the pressure of the surrounding spring water on his body.

With the help of the big stone on his chest, he quickly descended to twenty meters, but he still couldn't see the bottom of the pool.

Team Wang looked at Xu Zheng at this time and asked him with his eyes whether he should continue.

Xu Zheng nodded and pointed downward, intending to continue diving. Soon the two of them reached 30 meters of water.

The water here is colder and darker, and the time has almost reached five minutes. Xu Zheng is a little reluctant. He still has some energy left, but Captain Wang's mouth is already bubbling.

Captain Wang knew he couldn't hold on anymore, so he quickly untied the empty bottle tied to his waist, unscrewed the lid and took a deep breath of the air inside before he calmed down.

But Xu Zheng knew that this breath of air would not last long.

For safety's sake, he decided to go back up there.

He let go of the stone and pulled hard on the rope tied to his body with both hands. The special police standing at the edge of the pool sensed something abnormal in the rope.

He quickly pulled it up.

With the help of the special police above, Xu Zheng and the two rushed to the surface of the pool like rockets. As soon as their heads appeared, they both took a deep breath at the same time.

Xu Zheng looked at Captain Wang and saw that his eyes were red and bloodshot. It was obvious that his pressure under the water had reached a critical point.

"Team Leader Xu is indeed worthy of his reputation. I am ashamed of myself." Captain Wang calmed down for a while and complimented Xu Zheng.

Without personal experience, I really don’t know how stressful it is to dive into a pool.

Especially the dark depths, like a ferocious beast that devours all things.

Xu Zheng knew that his reputation was spread more widely in the SWAT system. He just smiled at Team Wang's praise, took the towel handed over by other SWAT officers and wiped his hair.

At this time, Squadron Mi came over and said, "Team Leader Xu, what's going on down there? Is there a passage?"

Xu Zheng shook his head, "It's hard to say. We dived for about thirty meters, but we didn't find that the space inside became larger as we went deeper, but the pool must have a bottom.

At the height we are at now, the pool will definitely not lead directly to the underground river. "

At a height of about two thousand meters, the water in the underground river could not rise so high no matter how high the pressure was. There was only one possibility. The other end of the pool must be in a nearby mountain.

And the water level there must be slightly higher than here to form the current situation.

Squadron Yan scratched his head. As soon as he heard that the bottom was still 30 meters deep, he gave up going into the water himself. "How about we send someone back to get the diving equipment?"

Xu Zheng waved his hand, "No, while my clothes are still wet, I will make another trip later. Others don't have to follow. By the way, if I don't come out in eight minutes, you can pull the rope again."

Team Wang, the diving instructor, is not good enough, and no one else has volunteered.

Now Mi and Yan also knew that Xu Zheng was more capable than them, so they did not stop him.

After waiting for a while, Xu Zheng almost calmed down, tied a rope, picked up a big stone, and jumped into the pool.

Familiar with the road, he soon arrived at a position more than 30 meters below the water pool. He continued to dive until he could hardly hold his breath. At a rough estimate of 50 meters, he finally made a new discovery.

He felt a horizontal current impacting his body in the water, and when the light shone through, it turned out to be a passage.

This made Xu Zheng feel very excited, and he quickly threw down the big stone in his hand, and took advantage of the force of his body to float up, and got into the passage.

But at this time, the rope on his body was not enough.

Without hesitation, he immediately untied the rope and continued swimming along the passage.

It became narrower as he went forward, but this horizontal passage was not long. Within 5 meters, he entered another pool.

At this time, Xu Zheng felt that there was still a breath of oxygen in his chest, but his chest tightness became more and more severe, so he quickly sucked up the air in the two empty bottles at his waist.

Then rush upstream.

It was definitely easier to float up than to dive down. Within three minutes, Xu Zheng saw a bright light above his head. When he was still five meters away from the water, he took out the pistol in his waist.

With a burst of strength, he jumped out of the water like a fish.
