The experts from the Bear Country who rushed to the scene listened to the sound of water at the entrance of the cave for a moment, and then left in a hurry. They did not have the courage to jump in to check, and even thought of staying away because they were worried that the water would continue to erode the soil below.

After the soil collapsed, the ground also collapsed, taking it with it.

Then they quickly reported to the superiors that the tunnel and underground river had been blasted through, and that heavy water was pouring into the tunnel.

After the flood hit, the mud covering Yu Fei's body was quickly washed away, and water continued to flow down the entire gap.

Yu Fei stood up, and the dirt he changed into was a good disguise.

He quickly followed the current and began to go deeper into the tunnel.

After walking for a while, he heard shouts and footsteps in the distance. Yu Fei quickly lay down on the ground again and covered himself with soil.

The water continuously flowing from behind, although the impact force is not as strong as the gap, the water flow is not small, so after quickly soaking the soil, the soil looks like a pile of mud that has been impacted.

Because the amount of water in the early stage is small, the gap will continue to expand with the impact of the water flow, and the water flow will also expand.

Therefore, as long as the water in the tunnel is not near the gap, it will not affect people's movements further away.

Of course, these people who came here had found some materials and tools and were ready to fill the vacancies.

When these people saw the water pouring from the tunnel in front of them, they immediately panicked. They didn't know whether they should run or go and try to see if they could block the gap.

In the end, these people decided to go and take a look. They thought the gap was not big enough and there was still hope of filling it. If they succeeded, it would be a huge credit.

When these people saw the pile of dirt where Yu Fei was hiding, they really didn't think much about it, thinking that it was coming from the water flow, because it didn't look like man-made stuff.

After these people left, Yu Fei quickly climbed out and continued to move along the tunnel.

The tunnel is not clean and empty. There are some triangular cones used to block the road, and there are also some large barrels that can be blocked by pouring soil or sand.

Yu Fei quickly and unceremoniously received the dragon ball space, and just followed the current. Yu Fei never surpassed the current, because the current was his amulet, the best prop he used to disguise himself.

This time, he advanced two kilometers in one go. With his powerful hearing, Yu Fei once again heard the sound of many people making noise and footsteps.

Then the triangular cones and large barrels he collected came into use. He quickly filled several large barrels with water, placed them randomly in the corners, and then threw many empty ones to the side. Yu Fei hid under one of the large barrels.

As soon as Yu Fei hid, dozens of people came over. These people carried tools and came against the current. When these people saw these large barrels and triangular cones, they glanced at them and walked around, because in the

In their opinion, it is normal for these plastic items to be washed away by water. It is even more normal for some of them to be accidentally filled with water and then block the back.

And now that the water has entered the tunnel, these triangular cones and large barrels are useless. The most important thing is that they just received the order to help block the gap in the tunnel to prevent the water from pouring in.

.

After these people left, Yu Fei, who felt the benefits of these triangular cones and large barrels, put them all away and continued moving forward.

Finally, after walking for a while, I found that there was electricity at the top of the tunnel. Because the lighting at the top was on, it seemed that the circuit in this section was different from the previous one, so it was not affected.

Yu Fei had to be even more careful now, because he had to worry about encountering a camera or something like that.

Exposed myself.

So in the end, Yu Fei came up with a stupid way to move forward with a big barrel on his head and drilled a hole in the bottom of the big barrel. This way, once the camera was found, because he was just moving in a straight line, the camera might also be able to capture him. But with

Using a large barrel as a cover, Yu Fei could pretend that the large barrel was being driven forward by the current. It would be difficult for anyone watching the surveillance to detect Yu Fei as long as they were in a daze and were not paying attention.

After going a long way in this way, Yu Fei didn't even meet anyone. He just met a small electric scooter that was easy to use in the tunnel. Unfortunately, the depth of wading was too limited. Once the water appeared, it couldn't be used and was abandoned.

Inside the tunnel.

This thing is similar to the Laotou Le that is common on domestic streets and can drive without a registration plate. It also has a body, which is a good disguise.

After advancing for a certain distance, Yu Fei, who was hiding in the big barrel, suddenly squatted down so that the bottom of the big barrel rested on the water, as if he was floating in the water, because Yu Fei saw a camera!

Yu Fei bent over and started to move forward, trying hard to simulate the state of things floating on the flowing water.

Just like this, he kept approaching the camera. When he came to the blind spot under the camera, he happened to see a fork in the tunnel in the distance.

The thing that Yu Fei was most worried about appeared. This tunnel actually has branch roads. So what does this mean? It means that the water has a way to flow out, and it will not fill up here quickly, and the people inside will not be too panicked.

Moreover, the personnel and materials inside may also be transferred to other places.

Yu Fei took out the map to check and quickly determined his location. Then on the map, he roughly saw the direction of the fork in the road.

Then I discovered that this fork in the road might lead to an even more uninhabited place. This tunnel seemed to be designed to connect the various bases of the Mao Xiong Kingdom in this area.

If this fork always exists, then my plan may be severely disrupted or even completely scrapped, because if the water is inside the tunnel and cannot form a large scale, it will not panic the people inside.

Even now, this fork has diverted a lot of water away, and the water flow in front has been significantly reduced.

So what to do?

Blow it up!

Yu Fei was so decisive. He entered the forked road and advanced dozens of meters, installed a delayed detonation device, turned around and left. Five or six minutes after he left, there was a loud noise, the forked road collapsed, and the soil from the top poured down.

, blocking this fork.

A Dragon Ball space can be used in many ways, including disguise and destruction.

Yu Fei sealed off the branch road and the water flow expanded again, which made him very satisfied. This effect was needed to create panic.

Moreover, the people of the Mao Xiong Kingdom were not sure whether the tunnel that Yu Fei had just exploded was blown up from the ground or from inside, and Yu Fei would not be exposed.

Then Yu Fei advanced a certain distance again and heard the noise from someone again. He stopped in a hurry, took out a large barrel and a triangular cone, and piled them together to disguise himself.

But after waiting for a long time, the sounds were still in the same distance, and there seemed to be no movement.

Yu Fei let go of his hearing. He had already learned the language of the Bear Country on his own. It was true that he had more skills than he could handle, and now he finally used them. Otherwise, he really wouldn't know what those people were talking about.

Soon Yu Fei was overjoyed, because he got important information from those people's conversations.

That is, the old base of the Bear Country was bombed, and the equipment and supplies that were rescued were piled in the tunnel. The base was not small, so there were quite a lot of things inside.

The reason why Yu Fei heard the people in front of him talking but not moving was because Yu Fei reached the farthest place where they were stacking equipment and supplies. Those people were outpost guards, so of course they couldn't move.

Some of them were discussing when they could leave this hellish place, and some were discussing why someone could control their missiles and blow up their base.

Of course, the most discussed thing now is the water that is poured into the tunnel. Anyone who doesn't fill the tunnel will be drowned in it.

They also heard the sound of Yu Fei blowing up the branch tunnel, but they could no longer spare the manpower to check, so they were all guessing where another explosion occurred. But they never expected that he thought it was the last one.

A fork in the escape route.

Yu Fei recalled the map. It was at least four or five miles away from the old base. Could it be that the tunnels within these four or five miles were all equipment and data rescued from that research base?

Thinking of this, Yu Fei might get a headache. Do you have to move all these things back by yourself? The larger the size and weight of the items, the more energy it will take to put them into the Dragon Ball space. It is impossible for him to move so many things.

Take them all in.

So if you want to get it, you can only get the core secrets. It may not be comprehensive enough, but as long as you get the core secrets, there are many talented people in the rest of your country, and Yu Fei believes that they can completely complete the task.

The water in the tunnel is still flowing, but now the water is only knee-deep. It is not possible to swim, let alone hide underwater, so it is extremely difficult to get close to it quietly.

But Yu Fei knew that at 00:00 tonight, another location he had selected as the main road leading directly to the underground river would be bombed. By then, Yu Fei estimated that the entire tunnel would be flooded in less than half an hour.

It's so full that most people inside can't escape.

That's when it's time for Yu Fei to leave, so it's best to get what you want before that time arrives.

Once the main channel of the underground river is blown up, not only people will die, but the equipment and other things inside will be soaked by water. Yu Fei believes that most things will be destroyed. Even modern people cannot store important documents.

It is stored in the computer hard drive. Once water enters, the data inside will be easily destroyed.

Yu Fei didn't come here to destroy. If he only wanted to destroy, he wouldn't have to enter the tunnel himself.

A large number of experts from the Mao Xiong Country outside were attracted and were fighting with the agents from various countries. But even so, the number of personnel and experts left behind was beyond Yu Fei's expectations.

Yu Fei thought that his sixth sense told him that if he rushed out rashly, he would have a high chance of death. Every time he rushed out to snatch this idea by force, his sixth sense would give him a strong sense of death crisis.

This is to remind yourself that this will never work, it is impossible to do it.

But there is not enough water now, and the scene where Yu Fei expected the people in the tunnel to panic and run for their lives has not yet appeared, so now is not the best time to take action. Yu Fei has to wait patiently and waste this precious time.

Wait for the water to rise.

If Yu Fei's prediction is correct, it will take at least half an hour from the time the tunnel enters the water until the water level starts to rise significantly. The time has not yet come. If the water depth reaches waist level, Yu Fei believes that he will be drowned in it.

The crisis here will make the people inside panic.

The Woolly Bear Country is further north, so it's colder, and they don't have much water resources here, so Yu Fei believes that unless they have special needs and special occupations, there shouldn't be too many other people who can swim and can't swim.
