The sound came from the woods more than ten meters in front of the left. Wan Lin carefully moved slowly on the canopy and approached the left front. He took advantage of the sound of the mountain wind blowing the branches and leaves of the trees, moved a few meters to the left, and quietly lay on the branches, picking up the leaves in front of him and looking ahead.

By the dappled light from outside the forest into the woods, two people in grass-green camouflage uniforms sat in the overgrown forest, both with their backs to a big tree, chatting in a language that Wan Lin did not understand.

Wan Lin turned around slightly, squatted on the branch, and tapped twice on the microphone in his ear, signaling that there was an enemy in front of the cliff behind him. Then he retreated a few trees on the way and quietly jumped to the big tree on the right. He was going to scout a little further from the canopy to see the defensive posture of the enemy around him.

At this time, it is not suitable to startle the snake, the enemy's defense deployment and the situation in the base are not clear, once the grass is taken by surprise, his own dozen or so people will be absolutely at a disadvantage in terms of numbers and firepower.

As soon as he jumped forward a dozen trees, he heard the sound of feet stepping on fallen leaves in the dense forest on the right. A patrol of six or seven men approached him from the side with automatic rifles. Wan Lin hurriedly glanced up, and slowly burrowed his body into the denser branches and leaves above.

Wan Lin knew that he was already close to the enemy's base at this time, otherwise the enemy's defense would not be so tight. The patrol walked past Wan Lin's hidden tree, and Wan Lin slowly picked up the leaves in front of him and looked down after they had passed. Just in time to see a six-man patrol disappear into the dense forest.

Minefields, fixed posts, and patrols show that this base is really well defended. Wan Lin muttered in his heart, turned around and climbed to the top of the canopy. He wanted to find a commanding height and take a closer look at the situation ahead.

He climbed to the top of the canopy and looked around. I saw a hundred-year-old cypress tree more than ten meters in front of me, with a tall crown like an open umbrella, standing tall above the dense forest. Wan Lin raised his binoculars and looked around, and when he saw that there was nothing unusual, he got up and ran from the canopy of the tree where he was to the big cypress tree.

As soon as Wan Lin scurried into the dense canopy, he heard someone scolding something, and then a sound sounded from under the canopy that seemed to be the door opening. Wan Lin was startled, and hurriedly raised his breath and quietly jumped to the top of the canopy, and his swaying figure caused a "rustling" sound of branches and leaves.

He had barely fallen into the thick canopy of the trees when he heard someone emerge from between the branches below, striking the branches with something as if to drive something away.

Wan Lin understood, his movements were a little louder when he jumped on this big tree just now, and he didn't expect that there was actually someone on the trunk. The man on the trunk thought that some animal was moving in the canopy, and he did not expect that it would be a large living person scurrying around in the canopy. So he poked his head out and banged the branches, trying to drive away the animals in the trees.

Wan Lin wondered in his heart, how could there be someone on the trunk? When he heard what seemed to be a squeak, he lowered his head from the top of the canopy, plunged his head into the canopy, and reached out to slowly pluck the branches to look down.

A small wooden house with a sloping roof actually hung on a thick tree trunk, and the wooden house was firmly fixed to the thick branches of the big tree, and the branches of the trees still grew luxuriantly foliage.

It turned out that this was a secret post set up by the enemy in the trees, and if you looked up from the woods, you really couldn't see the wooden house if you didn't pay attention. There were small windows in several directions of the wooden house, apparently this was an observation hole set up by the enemy, and a machine gun barrel in the shape of a horn rested on one of the observation holes.

When Wan Lin saw this secret whistle, he was immediately shocked into a cold sweat. Thanks to the fact that he came from above to reconnoiter the front, if he passed through the minefield through the woods, he would be directly exposed to the guns of this sentry. He understood that there must be specially trained professional soldiers in this base, and ordinary terrorists would never have designed such a perfect security arrangement.

Thinking of this, Wan Lin was a little worried that Bao Ya behind him would be exposed, Bao Ya did not have such dexterous light skills, and he would be exposed to the enemy's secret sentinel if he was not careful.

He hurriedly tapped lightly on the microphone three times according to the code agreed in advance, instructing Bao Ya to hide in place. Then he raised his wrist and looked at his watch, it was 6:30 p.m., and it was about to get dark.

Wan Lin looked up at the sky and saw that the sky was clear and blue, and knew that it should be a clear night full of stars tonight. He bowed his head and pondered for a moment, according to the custom, before the sun set, the enemy should change the guard, the day shift people should be laid off, and the night shift people should be on duty. You must clear the open and dark outposts around this place after the enemy has completed the change of guard, otherwise the assault team will be exposed to the guns of these sentry posts through the minefield.

After about half an hour, as Wan Lin expected, a team of more than a dozen people came out of the forest in front of them and came under the tree where Wan Lin was.

The wooden house in the tree suddenly opened a small door and threw out a soft ladder, and then I saw two people carrying automatic rifles out of the wooden house and down the soft ladder to the ground, and said something to the two people who had just come over, turned around and followed the team to the side of the forest, and the new two people climbed up the wooden house along the soft ladder, and put the soft ladder into the wooden house.

Wan Lin was secretly happy in his heart, according to the analysis of the number of people, there would be no more than twenty fixed and secret posts in this direction. He saw that the people in the wooden hut under him had already withdrawn the soft ladder and closed them, and hurriedly chased them from the top of the canopy in the direction of the changing of the guard below, which was a perfect opportunity to reconnoiter the enemy's open and dark sentry through the change of guard.

Wan Lin took the light exercise method to the extreme, fluttering on the top of the tree like a leaf dancing in the wind, and followed the enemy's changing of the guard team around the western forest, feeling the enemy's warning position clearly.

After changing the guard, the enemy walked along a forest path to the front, and Wan Lin carefully observed for a while, firmly noting the direction the enemy was taking. In this forest, the enemy has a total of 18 sentry posts, of which 12 are fixed sentry posts on the ground, in groups of two, and there is a group of fixed sentry about two or three hundred meters. The other six were spread out on three large trees similar to the wooden houses they had just seen.

The warning arrangement in this forest is in the shape of breaking waves, with the front and back, high and low, forming a perfect three-dimensional protection system.

Wan Lin nodded, and couldn't help but admire the enemy who was on guard in the base, this was definitely a protection system designed by someone with rich combat experience.

He turned around and returned in the direction he had come from, and on the way he saw Bao Ya squatting on a large tree branch to observe the surroundings of the Hubei Territory, apparently waiting for his order.

When Wan Lin suddenly poked his head out from the top of Bao Ya's head, Bao Ya was startled, and he quickly raised the automatic rifle in his hand.

Wan Lin stretched out his hand and waved it at him, and Bao Ya saw that it was Wan Lin who quietly got on top of his head.
