After Yu Fei entered the wild, he immediately looked for a safe location and changed his clothes into the outdoor camouflage clothing sold. He even painted his face with camouflage color and put on a camouflage hat on his head.

Then he seemed to have no assets and started sneaking, because Yu Fei knew that on his way forward, there would be a large number of overt and covert sentries and surveillance.

Sure enough, Yu Fei didn't go very far before he suddenly hid behind a clump of grass.

Under a tree in front, everything looks normal. In fact, there is a camouflage cloth under the tree, and there is a person hiding under it. At this moment, under the camouflage cloth, it seems that a branch has fallen on the ground. In fact, it is the other party's observation equipment.

Yu Fei's operation this time is of course mainly to obtain the research results of the island country. It is best to enter and leave without being discovered by the other party. Therefore, even if Yu Fei is discovered, the first thing he considers is to avoid it, and

It's not about eliminating the opponent.

So Yu Fei lay on the ground and slowly backed away. After going around in a circle, he changed the direction.

But after changing the direction, Yu Fei still found a hidden whistle.

Judging from the distance between the two posts, the two posts are on cross duty and the positions that can be monitored overlap. This arrangement method makes it too difficult to sneak past.

Yu Fei looked at the sky. Many people would think that night is the best time for penetration. In fact, it is not the case. Nowadays, there are many high-tech weapons. As long as people take out infrared equipment at night, the heat emitted by a person's body will be astonishing at night.

Like the sun.

Therefore, day and night were not friendly to Yu Fei. Yu Fei observed little by little and patiently saved up to find gaps in their sentry posts. After spending more than two hours, Yu Fei discovered more than a dozen sentry posts of the other party, and finally found a spot in the middle of the two sentry posts.

, found a way through.

This flaw was not due to poor arrangement of sentry posts, but to the good growth of the surrounding plants. Yu Fei did some calculations and found that he could pass quietly through the obstruction of these plants.

After finding the flaw, Yu Fei immediately started to take action. Like a swimming snake, he silently and slowly moved along the ground under the cover of his camouflage uniform. Those plants and his camouflage uniform provided him with a lot of resources.

Good cover.

Soon Yu Fei moved to the middle of the two sentry posts. At this time, the lights were dark, and both of them looked into the distance, paying less attention to the situation around them.

Yu Fei quickly passed the two of them, which could be regarded as breaking through the opponent's first line of defense.

The sentry posts on the first floor were very strict, and Yu Fei became more and more cautious. In order to keep it secret, the other party actually sent the most elite people to guard the posts. After Yu Fei passed by, he discovered that these people had all undergone strict training. Everyone

While on guard duty, Yu Fei didn't find anyone deserting or even napping.

After crossing the first line of defense, Yu Fei continued to advance quietly, and after advancing a few hundred meters, he suddenly saw a bird's nest on the branch of a tree in front of him.

But near that bird's nest, the owner of the bird's nest, a bird kept flying around but never landed.

Yu Fei let go of his eyesight and looked over. Through the gap in the bird's nest, he saw that there was a camera hidden in the bird's nest. It was very secretive because of the withered grass branches used to build the bird's nest.

The trees are tall, and the camera hidden on them has a large shooting area, so the monitoring effect is not very good.

No wonder the bird didn't dare to return to its nest. It turned out that the home was occupied. Yu Fei didn't pay attention before and almost didn't notice it. If he didn't think the bird was strange, he would have been discovered.

Yu Fei didn't know what kind of equipment that camera was, and whether it had the function of infrared shooting at night, so Yu Fei had to leave the other party's shooting range before dark.

So Yu Fei started to go around again. When he moved, he was very careful. Not only could he not make any noise, but he also tried his best not to leave any traces. He could not even let the surrounding vegetation shake to prevent the people behind the camera from noticing.

Own.

Yu Fei was relieved a little bit, but something painful happened. He bypassed one camera, but found that he had entered the shooting range of the next camera.

In particular, these cameras are all mounted at high places. Unlike the people hiding on the ground, many trees and grass have a weak blocking effect on Yu Fei, which makes it too difficult to sneak past.

.

I took the photo from above, and the photos behind many weeds were clearly visible.

Although Yu Fei was wearing camouflage uniform, it was still easy to be spotted when he passed under these cameras. After all, the surrounding objects were basically stationary. If a person moved, it would be too obvious.

Seeing that it is not far away from dark, if there is insufficient light, if these cameras have the ability to take infrared photos, they will inevitably be exposed.

Yu Fei was thinking about whether to leave through the previous gap, and when he thought of a way to go in, he saw someone coming from a distance, and there were quite a few of them.

Those who didn't come were all wearing various types of camouflage suitable for camouflage.

Yu Fei suddenly understood that these people were here to change shifts! The camouflage they wore basically covered themselves, and some of them added some straw clothes and the like.

This results in them barely being able to see each other's true appearance.

There was no communication between those people. After quickly walking over, the originally hidden sentry posts stood up and began to change shifts.

The person who got up from the ground seemed to have exchanged something with the person who came to change the shift, and then turned around and walked back.

These people who were changing shifts didn't communicate much, so they turned around and started walking inside.

Naturally, these people walked away from the camera in a swagger, and Yu Fei naturally would not let go of such a good opportunity. These people barely communicated with each other, did not look at each other, and just buried their heads forward, all of them were silent.

The cameras here will overlap each other's shooting areas, and these people will each walk through the areas where they are photographed.

When they were changing shifts, Yu Fei secretly made a disguise for himself with grass, and he happened to be wearing camouflage uniform, so he walked inside with these people.

Yu Fei believes that people who watch the camera video will not be able to find out that there is an extra Yu Fei among so many chaotic cameras. After all, there are so many overlapping shooting areas that the number of people seems to be much higher than the actual number of people. There is an extra Yu Fei.

, it is also difficult to see.

Yu Fei followed one through the shooting area, and then saw a bright whistle appearing in front of him. However, Yu Fei did not continue to follow stupidly. Instead, after leaving the area where the camera was shooting, he quickly took advantage of the cover of the big tree.

, and hid again.

Sure enough, after encountering the police, those people took out something to prove their identity, and then passed.

Yu Fei hid in the gap behind a few trees and could see clearly that each of those people's IDs seemed to be different.

Since he didn't have such a document, he naturally couldn't follow him through normal methods.

After crossing two lines of defense, the clear sentry in front is another big problem. There is one person standing five or six meters away, and all those people are

With guns and ammunition in hand, everyone stood in high spirits, no one was lazy, and everyone was very dedicated to their job.

It is simply impossible to sneak past such a wall of people, and they are not blind. They are only five or six meters apart, so there will be no blind spots in sight.

This made Yu Fei very worried. The secrecy level of the damn islanders was too high and the protection was too tight. This was the point where not even a fly could fly through.

Yu Fei slowly moved again, looking to see if there was any gap he could squeeze through. However, after going around five or six hundred meters, it was already dark and Yu Fei didn't find any gap he could squeeze through.

The opponent completely used human wall tactics to protect the base in the middle. Yu Fei didn't need to look at the rest of the place. This must be the case.

Yu Fei found a pit in the ground and sat on the ground to think. The terrain in this location was very low. As long as he didn't stand up or move around casually, he wouldn't be discovered.

Of course, from an optical point of view, others can't see him, so naturally he can't see others, but Yu Fei believes that if someone is approaching, he will definitely be able to detect it, because his hearing has been completely relaxed, and a bug is running on the ground.

He can hear all the sounds from the past.

Yu Fei's strategy this time was to try not to make any unexpected noise, even if others thought it was them.

Because the real superiors will understand that any coincidence should not be easily regarded as a coincidence, as it is easy to alert the snake.

After thinking about it for half the night, Yu Fei couldn't think of a way to break through the human wall. Those people changed shifts without even leaving any gaps. It was a shift of half people and half people. It was like planting rice seedlings. The person next to each person changed, and the next person did not change, and then

Then switch to the next one, and the cycle repeats.

In this way, even if people are not changing shifts, they will only be about ten meters apart. In this way, there will still be no loopholes when changing shifts. After all, people who are changing shifts also have eyes. Even when changing shifts, there are the largest number of people with eyes.

most time.

Yu Fei didn't know who came up with such a disgusting method. Without a direct confrontation, if someone wanted to get through, it would be as good as reaching the sky.

If he used force to force his way in, it wouldn't be too easy, but Yu Fei couldn't do such a thing to scare off the enemy, otherwise the result of the momentary pleasure might be that the mission failed.

Of course, the more peripheral the defense line, the stronger it is, which means the value of the things protected inside is higher.

Yu Fei sat in the pit, thinking about the way to enter. The night seemed to be very long, and the sky in the island country was no better than elsewhere.

The terrain he was in was considered to be in a mountainous area. The terrain was not very flat, but rather had a criss-crossed look of ravines.

However, the vegetation here is sparse and there are not many trees, so the sightline is better.

Yu Fei's family also lived in a mountainous area. He thought about it for himself, how could he pass through this human wall if the situation was the same near his village.

After thinking about it, Yu Fei looked down at the pit where he was, and he seemed to suddenly have an inspiration.

Yu Fei turned around and quietly left the pit, and continued to search around, but he did not search aimlessly, but searched according to the high ground and the direction of the water flow.

After more than half an hour, Yu Fei finally made a discovery in a small ravine.
Chapter completed!
