There are various smells mixed in the air, and there are almost everything washed down by the water. As long as it can enter the cave entrance, everything can be smelled here.

Yu Fei simply held his breath and moved forward, which showed that the smell was not very friendly.

Knowing that there was an exit when the water flowed up, Yu Fei was naturally very motivated and walked faster and faster, leaving behind him a series of footprints and even splashes of mud.

After advancing for half an hour, Yu Fei took a breath and realized that the smell was still indescribable, so he continued to hold his breath and move forward.

This time he was very lucky, there were no big rocks blocking the road, and he quickly reached the exit.

Yu Fei did not rush up, but listened quietly below to see if there was any movement above the ground.

After waiting for a long time, he only heard a voice coming from a hundred meters away. He was worried, fearing that if he showed his head, he would be caught in the sight of others or under surveillance.

So he used his spiritual energy to start exploring again, and after searching for nearly a hundred meters, he finally knew where this place was.

Fifty or sixty meters away from here is a drainage outlet, where a large amount of domestic sewage is discharged.

This seems to be the reason why this cave has such rich flavors.

Fortunately, it had just rained. Although the smell was bad, a lot of the filth was washed away.

Yu Fei climbed up to the entrance of the cave gently, and after looking into the distance, he understood that God did not favor him this time, and did not send him directly to the edge of the research base, but to the little boy who he did not intend to go in.

On the edge of town.

It seems right to think that the confidentiality level of that research base must be very high. I am afraid that even for the disposal of domestic waste, they have their own channels or methods and will not leave such obvious flaws.

However, Yu Fei knew that after he arrived here, even if he passed through all the peripheral defense lines, he didn't know how much energy he saved.

It was almost dawn now, and the town was very quiet. No wonder I heard almost no movement. It turned out that everyone was sleeping.

He stretched out his head and looked around to make sure there were no monitoring or other equipment around, and then Yu Fei walked out of the cave.

Now it's time to find the exact location and entrance of the research base, and find a way to sneak in. As long as you enter it and get the things, even if there is an accident or you are discovered, you can safely make a big noise and escape.

Well, it’s just me alone, so I don’t need to consider the influence of other factors.

The map given by Chen Dong only told Yu Fei that the research base was on the edge of this town. Chen Dong didn't know where it was exactly.

After all, with such a tight defense line on the periphery, it would be almost impossible to put people in if people were not inserted in advance. After being discovered later, it would be almost impossible.

While it was still dark, Yu Fei quickly became familiar with the surrounding terrain. Even if he couldn't act immediately, he had to become familiar with the surrounding terrain and find a good hiding place.

After walking around the town, Yu Fei was sure that this town was just a fucking cover.

People here don’t farm, there are no fields around, and there are no factories or anything like that. How can people here survive on the air?

Therefore, Yu Fei judged that this town was definitely a deceptive place. If a spy really walked in rashly, it would be like entering a hole dug in advance and impossible to climb out of.

No wonder Yu Fei thought that the houses here were so new, and thought the people here were very rich. It turned out that they were just built to deceive people.

After Yu Fei saw through the truth, it became increasingly impossible for Yu Fei to enter this town, but the problem came, he still couldn't find the location of the base.

without any

With foreign aid and intelligence, Yu Fei could only rely on himself. He sat under a big tree, took out a bag of compressed biscuits and mineral water, and started thinking while eating.

Yu Fei thought about the outside defense line, which seemed to be surrounded by a circle. Generally, when protecting something, the periphery is a circle, and the most important thing is most likely to be in the center of the circle, even if it is not at the absolute center of the circle.

, also in the middle of the center of the circle!

Based on his own memory and experience, Yu Fei thought about the outer circular defense line, and then observed the terrain in all directions.

Soon his eyes were fixed on a small hill on the edge of the town.

The hilltop looked unattractive, the grass on it was very sparse, and the trees looked wilted and lifeless.

The hilltop was right in the middle of the circle. Yu Fei stared at the hilltop for a while and found that there were obvious traces of artificial camouflage on the hilltop. The trees seemed to have been planted not long ago and had not completely returned to the sun, so the leaves were a little dry.

The other party seemed to be trying hard to disguise the hilltop, making it look similar to the surrounding hills, as if they were afraid that others would notice the difference.

Yu Fei was almost certain that the research base was there.

After he finished the biscuits and drank the water in several mouthfuls, he did not throw away the package, but put it into the Dragon Ball space, because if these things were left behind, they might keep their whereabouts.

Yu Fei slowly walked towards the hill. The defense on the outside was very tight, but inside it seemed to be very lax. Yu Fei only found a few hidden sentries and some cameras, which only monitored important paths and the like.

Yu Fei thought about it and felt that these people probably thought that no one could break through the outer defense line silently, so the internal defense line was relaxed.

This saved Yu Fei a lot of energy, and he easily reached the top of the hill. He was only a hundred meters away from the foot of the hill before he finally stopped.

Sure enough, at the foot of the mountain, a hole was dug out manually, as big as a tunnel entrance on a common highway in China.

There are many vehicles parked outside. The types of vehicles are very diverse, including engineering vehicles, large transport vehicles, and cars for transportation.

There were quite a few people stationed at the entrance of the cave. After Yu Fei observed it, he estimated that these people were soldiers, because their spirits were obviously different. The people standing guard all had serious expressions and fierce eyes.

It's almost dawn, so these people have already gotten up and started morning exercises. They have cleared a large open space at the entrance of the cave. As their training base, they also surround the entrance of the cave. Others want to enter under the noses of so many people.

, is simply a delusion.

Yu Fei estimated that there were about 150 of these people, which was the number of people in a company.

Those who are training are training, and those who are standing guard are standing guard. They are worthy of being elites. Yu Fei did not find anyone who was lazy.

It is very difficult to pass through here, even if someone does not deliberately set up a strong defense line, because the open area at the entrance of the cave is too large. As long as there is a sentry who is not distracted, it is impossible for anyone to pass through.

Sneak in.

Yu Fei was not in a hurry to break through. No one knew that he had arrived here anyway. As long as he was patient enough, he could always find opportunities to get in. If he acted rashly, he might be exposed.

It had been stolen by Yu Fei several times before. I guess the people on the island would go crazy. If someone ruined the results, they would still have technicians, but I would get nothing.

Yu Fei found a seat and patiently observed and waited.

After observing for a long time, Yu Fei finally discovered that no one from the outside world seemed to need to enter here. The things they transported were handed over to the people stationed here, who then sent them in.

.

This is true

This is a wonderful method, so that if outsiders want to sneak in, it will be impossible. They will not give anyone a chance to enter here.

People in the military camp are still completely closed, and those who can come into contact with people in the military camp can only enter through the main entrance and hold documents.

This is very troublesome. These people are simply too strict in their management.

Yu Fei also thought about using hypnosis, but the sentry posts in the military camp were more particular, and they were all cross-eyed. If Yu Fei couldn't hypnotize everyone at once, someone would sound the alarm, and he would be exposed.

So if you want to get in, you still have to enter through the main entrance honestly, and then use tricks on those who are more relaxed inside. It is impossible to use the sentry position outside.

So Yu Fei turned his attention to the transport truck outside. He quietly found his way to the edge of the road where the transport vehicle must pass and hid it.

But this time, at night, no car came. Yu Fei had no choice but to continue to wait. He waited all night. Finally, at almost noon the next day, a car finally came.

The location chosen by Yu Fei was in the blind spot of the sight of the sentry on the other side of the military camp, so that he would not be discovered by the people over there.

What came was a small truck. Just as it arrived at the location calculated by Yu Fei, Yu Fei quickly jumped out.

The other party brakes quickly. As a driver, you will definitely stare at the person you are about to hit at this time. This is a driver's habit.

But Yu Fei relied on this habit. When the other party's car was about to stop completely, Yu Fei raised his hand fiercely and started hypnosis.

There was only the driver in the car, and he was quickly hypnotized by Yu Fei.

It was so difficult to finally find a lone person. Yu Fei hurriedly climbed into the car and started interrogating him.

But the driver didn't know anything. He was just responsible for transporting things to the military camp and then handing the car over to the people inside the military camp.

He probably only knew that what was in the car was food, but he didn't know anything else.

Everyone who enters the military camp has two IDs each time. One ID is never changed. Drivers have it all the way. The other ID is for people who perform different tasks each time. They will give one ID.

open.

Therefore, it is impossible for others to impersonate this driver. Yu Fei also knows that only this driver can drive in and hand over this car.

However, the results of Yu Fei's observation for a day were quite satisfactory. He knew that the people in the military camp and the supplies they received had all been driven into the artificially dug tunnel, so Yu Fei decided to hide in the car and be captured by the opponent.

Ship it in.

Yu Fei was able to confirm this time that there was no infrared detection device on the other party's door. The other party seemed to drive the car into the tunnel before checking it. Every time after entering the car, more than a dozen people followed him in, and they were armed.

Yu Fei's request was to go in first and figure out a solution after entering, so he asked the driver to continue driving while he hid in the car.

The carriage is indeed full of food, including vegetables, fruits, and even daily necessities.

Yu Fei hid in the middle of a pile of boxes. The driver drove on the road again, walked for a while and finally arrived at the military camp. He first parked his car and accepted ID inspection, and then waited outside the military camp while the people in the military camp drove in to deliver the things.

When the car started moving again, Yu Fei knew that he was finally going to enter the tunnel he had been staring at for two days.

Even Yu Fei knew how long it took for the vehicle to drive in. He silently calculated the time in his heart and also calculated the distance. Yu Fei guessed that after entering the tunnel, he drove more than 20 meters before stopping.

But Yu Fei kept listening to the noise outside the car, and heard that the people who drove in this time, and the people who followed them, left quickly after parking the car!
Chapter completed!
