Others deceive each other. This is the prerequisite for Yu Fei to know that this plan can succeed, because the purpose of everyone staying here is for the scientific research results of the Bear Country, so everyone wants it.

But who doesn’t know the danger here? Knowing the danger, in essence, everyone is trying to trick others, and they all want others to try it out, and then they themselves will be like the mantis stalking the cicada and the oriole behind.

Everyone will think that they are very smart. This is the essence of human stupidity.

So what Yu Fei did was just the butterfly at the beginning of the butterfly effect, and the rest were accomplices. They would help Yu Fei complete the next actions and push things in the direction Yu Fei wanted.

Although Yu Fei did not connect all the teams, because of the rhythm that Yu Fei led before, other teams followed Yu Fei's example and contacted each other. This resulted in this big network being actually woven with the help of other teams.

Well, except for a few teams that really don't fit in with each other, this is just a very small number of cases.

Yu Fei finished fabricating the false information himself, and the other teams started planning to move the tunnel exit sooner or later. Even if they didn't have time to leave, they also set their goals.

After all, the window time set by Yu Fei is three days later. Only the team will change the time to a shorter time, and no team will change it to a longer time. After three days, as long as the teams who get the news, whether far or near, will gather at

Around the tunnel exit.

Yu Fei himself had no intention of approaching the tunnel entrance early the next morning. Instead, he followed the tunnel entrance and began walking and groping along the terrain that he analyzed to lead to the old base, looking for tunnels hidden underground.

Although Yu Fei controls spiritual energy and can conduct a certain range of detection underground, just like eyes, the loss is too great, and compared to this vast terrain, Yu Fei's detection range is really limited, so it is a bit useless and exhausted.

It is basically impossible for me to walk a certain distance to locate my location once. If I only find one location, it is actually difficult to achieve anything.

Yu Fei actually knew in his heart that his only chance might be inside this seemingly impossible tunnel, not outside it.

The outside of the tunnel seems to be an opportunity, but in fact, Mao Xiongguo also knows that others will target that distance and is very defensive, and the possibility of success is almost zero.

Inside the tunnel, Mao Xiongguo thinks it is very safe. No one else can find it, and even if they find it, they can't get in, so they will relax their vigilance.

Moreover, it is impossible to cooperate with others to do this. Although Yu Fei was very nice when he deceived others before, what he said was that they could cooperate with each other and share information. If they gained something, they could share it, and everyone would gain something.

But in essence, everyone is a cheat and everyone wants to monopolize it. Moreover, when cooperating, they may be used as cannon fodder and betrayed at any time.

Therefore, this matter can only be done alone, and cooperation is impossible.

Therefore, Yu Fei had no intention of cooperating with anyone, no intention of leaving his back to others to protect, and it was even less likely that he would share the secrets he obtained with others.

Because Yu Fei wants to obtain this secret, not for himself, nor for the credit and bonus. He essentially wants to obtain this secret for his own nation and country. If others also have it, then his country is not the only one. With opponents, maybe

You will encounter all kinds of bad things again.

This kind of thing is like a strategic weapon. It is best if you have it yourself and others don't have it. If others have it, then your own thing will not have such a great deterrent effect.

Therefore, Yu Fei had no intention of going to the entrance of the tunnel to watch the excitement. He just wanted to trick them into going there, testing the strength of the Bear Country, and attracting the attention of the Bear Country. It would be better to consume the strength of the Bear Country so that he could make it easier for himself.

work.

Teams from various countries were heading towards the entrance of the tunnel, but Yu Fei stayed away from there and started walking in the wilderness.

, looking for the location of the tunnel.

Because it is unrealistic for Yu Fei to search directly with spiritual energy detection, Yu Fei first judges whether there is a tunnel underground in this place based on other information. After he is 80% sure, he then uses spiritual energy to confirm it. This is the most reasonable

method.

Without knowing whether there is a tunnel underground and without detection tools, it is actually very difficult to find it manually, but it is not without basis to judge.

Experienced people will know that if a tunnel is built underground, the flow environment of groundwater will be destroyed, causing the flow of groundwater to be diverted, cut off, or the water flowing out of the ground suddenly becomes turbid.

Changes in groundwater will be reflected on the ground. For example, good springs suddenly dry up, water sources appear in places where water sources are impossible, and large areas of plants die in certain places where water-dependent plants grow.

Yu Fei and the others first marked the places where it was impossible to build tunnels on the map, and then walked along the places where tunnels could be built.

Then he observed the direction of the mountains and rivers here, and then observed the clues around him. Soon Yu Fei discovered a dry spring. This spring should have existed for a long time. The water flowing out eroded a stone and created a deep pit.

But the spring suddenly dried up.

This is very unreasonable, indicating that this spring may have been cut off or diverted, and then the tunnel may pass through the source of the water in this spring.

Yu Fei followed Ma Laodao before and learned some Feng Shui knowledge. In fact, Feng Shui knowledge is not just the theory of ghosts and gods, but more of the scientific knowledge summarized by the ancients through a lot of exploration.

Feng Shui masters can judge the terrain here thousands of years from now and the trend and location of water flow through the topography. This is actually a basic skill.

If a certain Feng Shui master helps someone locate a tomb and digs out a spring, then this Feng Shui master must be cheating and has not even learned the basic skills.

So Yu Fei stood at a high place and could easily see where the spring water flows from. Based on his knowledge of Feng Shui, he seemed to have the ability to see through the ground and see the flow of water dozens of meters underground.

Location.

Then Yu Fei observed the growth status of the plants on the mountain, and he had a rough idea. He took Scar and walked to a hillside near the bottom of the valley.

"What do you think the chances are that the tunnel is down here?"

Yu Fei asked Scar with a smile.

"I don't know! I just know that the cessation of spring flow is usually caused by the forced diversion or cessation of groundwater. This may be related to the excavation of tunnels!"

Scar shook his head. He didn't have as much knowledge stored in Yu Fei's brain, so it was difficult to judge.

Yu Fei nodded, without showing off anymore, and stretched out his hand to lift the ground. The spiritual energy poured into the ground along his fingers, and went deep into the ground in a straight line.

Three meters...five meters...seven meters...ten meters...

Finally, when it was eleven meters deep, and Yu Fei felt that he had made a mistake, the spiritual energy encountered a different kind of obstacle, which suddenly made it difficult for the spiritual energy to penetrate deeper.

Because the difficulty Yu Fei encountered was reinforced concrete that was difficult for spiritual energy to penetrate!

The only possibility for reinforced concrete to appear underground is that when the tunnel was built, it was the edge of the tunnel for reinforcement.

Yu Fei controlled his spiritual energy to go deeper, penetrated the reinforced concrete, and encountered a layer of special material, which was like plastic and very strong. After passing through, he encountered a whole layer of metal, which should be stainless steel, and finally penetrated

After applying a layer of paint, we finally entered the tunnel.

But there is a characteristic of spiritual energy. These are not real eyes, but what they come into contact with can send back some information that can be used for reference by controlling Yu Fei, so

It cannot be said that once you enter the tunnel, you can see the situation inside the tunnel.

Yu Fei was now certain that there was a tunnel below, and he also knew the thickness of the outer wall of the tunnel.

Yu Fei controlled his spiritual energy again and completed a circle along the outer wall of the tunnel. This way he could judge the size of the objects that could pass through the tunnel.

The top of the tunnel is a semicircle, and then there are vertical walls that go down about three meters. The general shape is like a cave dwelling dug by people on the Loess Plateau in the north.

The width of the tunnel is about seven meters, and ordinary vehicles can drive side by side at will, which is the width of two lanes.

Such a tunnel can have high traffic efficiency, support motorized transportation in both directions at the same time, and will not encounter problems such as crossing the road or bumping into porcelain.

But that's all Yu Fei can be sure of. If you want to know more, you have to dig through the surface into the ground, dig a hole in the tunnel and go in to see for yourself.

But it was obviously impossible at the moment. He needed to identify more locations in the tunnel and find a more suitable starting point.

"I was really right, there is a two-lane tunnel below!"

Yu Fei took back his hand and said to Scar.

"How deep?"

Scar looked around and felt that they were digging a tunnel in this place. If they hadn't confirmed it through on-the-spot investigation, they wouldn't have believed it. The Bear Country didn't engage in infrastructure construction, but its strength didn't seem to be weak.

"Eleven meters!"

Yu Fei reported the accurate depth.

"What! This is too deep. Even if the terrain here is complicated, eleven meters is too much. Every time you go deeper one meter, the difficulty will be different!"

Scar was shocked. To be honest, he had also heard about the difficulty of tunnel excavation. The deeper the tunnel, the harder it might be, and it would be easier to dig out surprises. Once a mistake is made, the price will be huge.

"I guess they are doing this to avoid detection by geological satellites high in the sky, because geological satellites also have a certain ability to penetrate the earth's surface for detection. Some countries even use geological satellites to prospect for minerals. This shows that the technology is terrible, and they dig too shallow.

, it may be exposed in minutes!”

Yu Fei expressed his conclusion.

"I see. Sure enough, no opponent can underestimate us. Others only know that we have the Great Underground City, but they didn't expect that the Furry Bear Country also has one!"

Scar couldn't help but nodded, feeling that the strength and heritage behind a country should not be underestimated.

"Those who have the ability to do it must be doing it. This is a secret. No one will go out to promote it, but they will promote others. Maybe our country's infrastructure capabilities are too strong, and other countries are afraid of doing it, so they promote it together.

Us, give us some trouble to gain psychological balance!"

Yu Fei knew that many countries have such underground facilities, and they are very common. The earth is generous and can accommodate humans to do many things.

Countless countries have built underground air-raid shelters, doomsday cellars, underground cities, underground tunnels, etc.

"It turns out that I am naive."

Scar nodded.

"Let's go, keep looking!"

Yu Fei nodded and continued to search with Scar. He wanted to confirm a few more places, then roughly determine the direction of the tunnel, and then find the most suitable place to start.

Anyway, there was still plenty of time. Yu Fei deceived the teams from various countries to gather at the entrance of the tunnel. In fact, he also had another purpose, which was to prevent the Bear Country from transferring equipment and personnel and buy himself time.
Chapter completed!
