Although Yu Fei couldn't see far away with his spiritual energy, he could roughly know the direction of the tunnel, so following this direction, it would be easier to find the next point.

After walking forward for several kilometers, Yu Fei stopped to find a second location. The reason why he had to walk so far was because this was also a good location if digging was needed.

Moreover, Yu Fei wanted to be sure of one thing, that is, whether the tunnel had any forks or changes in direction.

About four kilometers away from the previous point, they came to a wasteland. It was fairly flat, the terrain was not very undulating, and the location was relatively stable. It was a good place for digging tunnels.

The people of the Bear Country naturally did reconnaissance and planning when digging tunnels. It is impossible to choose a starting point and an end point and start digging in a straight line connecting the city. That would be courting death, and it is basically impossible to dig through.

So Yu Fei just determined a general direction. He knew that occasional turns and changes in direction in the tunnel were inevitable.

According to Yu Fei's inference, the tunnel is under this wasteland, but this wasteland is not small, so accurately determining the location is a technical matter.

Yu Fei stood in the middle of the wasteland. He first looked around to see the general terrain of the mountains and rivers, and then walked on the wasteland to carefully observe the changes on the ground.

"The terrain here is flat and there is sufficient water on the surface. I'm afraid it's difficult to judge."

Scar looked around and felt that this was really not a good place to easily determine the location.

The plants around here are mainly herbaceous plants. The impact of deep groundwater on the plants does not seem to be very great, so they all grow about the same.

"So we still have to look at the waterway. The water on the land surface flows from high to low, and so does the groundwater. Unless there is pressure. If you look at the mountain pass in the east, the surface water over there flows out and goes south. It stands to reason that the groundwater is the same, but underground

There will be obstacles, and if there are some obstacles that water cannot penetrate easily, it will look for places that are easy to penetrate.”

"There is Stone Mountain to the south, and also to the west. Although the gaps between the stones can allow water to flow through, they also depend on the type of stone. The stones in the two Stone Mountains do not belong to this type, so the remaining direction is the north, and the terrain of the north is

It’s a little lower than the east side, so the water must go around to the north and around those stone mountains to pass through this area!”

Yu Fei began to teach Scar a deeper judgment method. This seemed to be science, but Yu Fei did not learn the knowledge from textbooks, but learned Feng Shui from Ma Lao Tao.

This also confirms that Feng Shui is a science obtained by the ancients who summed up their experience, but it has always been misunderstood by most people. In addition, the ancients were often conservative about culture and unique skills.

The pedantic ideas such as passing on women continue to be shrouded in mystery, making people mistakenly think that it is theology.

After Yu Fei finished speaking, he took Scar and walked north, walking nearly a kilometer, and then encountered a small spring, which kept trickling out and nourishing this area of ​​land.

"What can you see from this spring?"

Yu Fei pointed to the spring and asked Scar.

“Has the groundwater been cut off?”

Scar really doesn't know, he can only rely on guessing and deception.

"No, this spring appears because this is the location of a geological fault. It looks similar on the ground, but in fact the underground structure is different. One side is stone and the other side is soil. When the groundwater in the soil changes direction here,

The constant impact created a small gap in the geological fault!"

"Try the water temperature. It's very cold. It means that the depth of the water is not deep. Deep water is warm instead. It means that the water has been diverted to the surface here. The reason is the rocks in the ground, so we have to go northeast.

, completely away from the underground rocks, which is also a suitable place for digging tunnels.”

As Yu Fei said this, he walked some distance northeastward with the scar in his hand.

"At most, we can analyze it as far as here, and at least reduce the scope by three-quarters."

Yu Fei stood at the corner of the wasteland. It was a corner, but the area was quite small.

"I'm left to analyze. The tunnel passing through this place will obviously have to turn due to the influence of the terrain. However, for the sake of safety and maneuverability, the curve must not be too large. It is best to make it gentler, even if the distance is increased.

In fact, the speed has accelerated.”

"Analyzing it from an arc angle, if they want to avoid waterways, the arc of the tunnel may be similar to that of waterways, so that they can avoid waterways as much as possible and reduce corners, so we retreat a certain distance, yes

The place with the greatest possibilities!”

Scar didn't understand Feng Shui, but he knew some general rules of road construction, and now he hurriedly put them to use.

"That makes sense!"

Yu Fei nodded after listening.

The two people retreated a certain distance, and this time they really couldn't narrow the range any further.

Yu Fei took action and began to use spiritual energy to probe downwards on the ground, looking for the location of the tunnel.

After the first failure, the two of them analyzed it, became bolder, and retreated some distance.

This time, when Yu Fei thought he had found the wrong location again, he finally found construction waste in the soil. He was pleasantly surprised. This meant that the tunnel was on the left or right side. The existence of construction waste was most likely for filling.

holes.

Sure enough, it was right on the edge. Yu Fei finally found the tunnel. Sure enough, the tunnel turned in the same direction as the water flow at this location.

It is estimated that the groundwater is very ferocious, so the Bear Country has to stay away from the limelight for a while and dare not cut off the groundwater. Otherwise, the strong water pressure and impact of the groundwater may destroy the tunnel.

Another location was determined and Yu Fei marked it on the map. Of course, he knew it well.

The two of them started looking for the next location without stopping.

It was easier to find the third location, because of the surrounding terrain, there was only a narrow location suitable for digging tunnels. Yu Fei checked it and it turned out to be the case.

After their search, they found that the tunnel had turned a big bend. In fact, this discovery was just reasonable, because originally they saw from the map that the terrain suitable for digging the tunnel showed an arc as a whole and could not be a straight line.

.

I just haven't found a fork in the road yet, and I don't know if this is an underground tunnel network extending in all directions.

This is actually very difficult to find. It mainly depends on luck. As for the location suitable for digging a branch road, Yu Fei and the others have found more than a dozen most suitable locations and a dozen generally suitable locations. It is impossible to visit them all. There is no time at all.

allow.

So we can only make sure there are no side roads within a short distance, because the plan that Yu Fei has formed in his heart no longer allows Yu Fei to have so much time to explore, and he does not allow the existence of side roads.

After finding three points, determining the location of the tunnel, and determining an underground hydrological environment, Yu Fei's first step of the plan was completed, followed by the second step of the plan.

Yu Fei began to detect the underground tunnel from a distance of seven or eight meters, and began to gradually determine whether there was a fork in the underground.

This is a truly energy-consuming job. Yu Fei's spiritual energy will be depleted during the process of use, and his energy will also be depleted.

Therefore, we can only eliminate some locations where there are no forks in the road in advance, and focus on observing the locations where it is possible for the other party to build a fork in the road.

Even so, Yu Fei was very tired. After working hard all day, he was almost exhausted at night.

But fortunately

There isn't much distance left, so we haven't found anything yet.

Yu Fei practiced for a night to recover. He could not completely exhaust his energy because they were not in his stable and safe motherland, but in a foreign country.

Scar protector Yu Fei is practicing, and both of them have absolute trust in each other, so Yu Fei directly enters deep practice to recover quickly.

While they were practicing, teams from various countries actually arrived near the entrance of the tunnel under Yu Fei's clever trick.

Even if you want to be a mantis or an oriole, you won't say that you won't come at all, but you will observe from a little distance.

Around the entrance of the tunnel, starting from two or three kilometers and extending to ten kilometers, basically all the remaining teams from various countries are within this range.

Everyone in the Mao Xiong Kingdom seems to feel that the storm is coming, and perhaps all it takes is one fuse to detonate it completely.

Teams from various countries can even occasionally meet together, or even sit together to discuss the intelligence they have obtained and analyze whether there is a driving force behind this incident.

However, Yu Fei's secretiveness, and the fact that teams from various countries all had reservations about what they said, and no one was willing to completely believe others, could not analyze the reason at all. Instead, because the information received by each team was incomplete, it was all their own.

After piecing together the information, they all believed that their judgment was correct.

With such mutual confirmation, they strengthened the rumors created by Yu Fei and believed that there was no problem with the time and place mentioned by Yu Fei.

Of course, with them crowded together like this, the rumors became more and more fermented. Everyone was almost convinced that the base of the Bear Country was infiltrated and controlled by the islanders, and it caused chaos within the Bear Country, and even angered the people.

After leaving the Bear Country, the Bear Country launched a ruthless purge of the intelligence teams of various countries. During the purge, almost all countries suffered losses, and everyone now has a strong opinion of the island country.

Also, under Yu Fei's deliberate efforts, everyone believed that the original source of the news was the intelligence personnel of Bangzi Country. Some even said that he knew that people from Bangzi Country not only leaked the news, but also said with certainty that they had the information.

There is conclusive evidence that the islanders control the remote support base of the Bear Country.

Suddenly, the Bangzi Kingdom became an image in everyone's mind of having no bottom line to harm the people of the island country.

However, the rumors were brewing so much that the people in the Bangzi and Island countries who were deep inside were not aware of it, because when others met them, they did not take the initiative to mention it and pretended not to know.

Because no one wants to play against teams from these two countries at this time, which is equivalent to wasting one's own strength in vain.

It's just that the people of the island nation found that the teams from all countries looked at them unkindly, which made them confused. Could it be that these people still held grudges about the robbery of fragments in Africa before?

The people in the island country are so aggrieved that they are about to cry. Although they may not know the exact situation and whether their country has received it, their country is now severely blocked and can use the people to make a living.

describe.

These two villains didn't know that not only were they taking a huge blame, but they were also being framed by other teams, who had a tacit understanding of each other. When everyone met their team, they all told Yu Fei's fabrication about the time and date of delivering supplies to the Bear Country.

I told them the location and said it very seriously.

Therefore, the teams from the Bangzi Country and the Island Country, while constantly confirming the intelligence, squeezed into the middle of the ten-kilometer range and came to the edge of the distance where a large number of Mao Xiong Country was deployed. They are all greedy and are notoriously greedy in the world.

, so they all want to occupy favorable terrain and try to get the research secrets early.
