Xu Yuntian nodded, "Well, please note down those specific locations. We will use electronic interference to interfere with the wireless pinhole camera later." Xu Yuntiandao.

The wooden flies continued to fly forward and soon arrived near the secret whistle at one o'clock. They saw a secret whistle leaning against a tree, holding a sniper rifle equipped with a muffler.

"Brother Tian, ​​I saw the secret whistle in the direction of one o'clock, using a sniper rifle equipped with a muffler." Yan Xiaoyu said quietly.

"Let the Wood Armor Fly look at the other secret whistles to see if their situation is the same." Xu Yuntian said quietly.

Yan Xiaoyu continued to use the wooden flies to reconnaise other secret whistles. After the six secret whistles were reconnaissance, Yan Xiaoyu said to Xu Yuntian: "Brother Tian, ​​the six secret whistles use sniper rifles equipped with mufflers. They are all equipped with wireless headphones. They will report any movement at any time."

"Oh! The equipment is quite advanced! Let the wooden flies continue to push forward and see what else?" Xu Yuntian said to Yan Xiaoyu.

The wooden flies flew forward for about 100 meters and found a far-infrared protection network system on the ground, which was connected to the trees on the ground. Not to mention people, even birds would not fly in.

"Oh! Brother Tian, ​​there is a far-infrared protection network system one hundred meters behind the secret whistle. The protective space has three meters of space. Flies cannot fly over. The wooden armored flies cannot go over again, otherwise they will be discovered." Yan Xiaoyu frowned.

Xu Yuntian nodded, "Well, the protection of the Crow Door is quite strict. I guess there should be no obstacles after the far-infrared protection net. Let the wooden flies return." Xu Yuntian said.

After the wooden flies returned, Xu Yuntian, Yan Xiaoyu, and Yang Feng immediately walked forward quietly. They soon arrived at the organ area. Xu Yuntian saw that there were organs everywhere.

Turning his head to Yang Feng, he said, "Yang Feng, go and open up a safe road."

Yang Feng nodded and said, "Okay, give me ten minutes, I will open a safe passage soon!"

He quickly stepped into the government area. There was a weed in front, and there was a transparent thin line inside the weed. Yang Feng turned his head and looked at the left and saw a tree as thick as a bowl.

There are crossbow arrows under the trunk of the tree. As long as you touch the thin line, the crossbow arrows will be fired. Yang Feng approached the tree, pulled out his knife and cut off the ropes that fixed the crossbow arrows, and removed the crossbow arrows.

Then he continued to walk forward, and soon found something was wrong in the grass in front of him. He picked up a stone and threw it over. The stone fell to the ground and sank quickly.

"Damn it! There is a trap in front of it!" Yang Feng immediately inserted a branch on the ground to mark it.

Yang Feng walked around the trap and continued to walk forward. After about eight minutes, he found that there was no mechanism ahead, which means that he had already walked out of the mechanism area.

So they made a OK gesture to Xu Yuntian and Yan Xiaoyu. Xu Yuntian and Yan Xiaoyu immediately followed the branch marks on Yang Feng's road, and they soon arrived by Yang Feng's side.

The three of them continued to approach, about a hundred meters away from the camera, and they stopped. This was the camera surveillance area, hidden behind a big tree.

Xu Yuntian took out something the size of a matchbox, pressed the button, and made a dripping sound, and a red light lit up on the matchbox.

Then Xu Yuntian pulled out a slender antenna, and the red light flashed immediately. Xu Yuntian immediately pressed another button and made a dripping sound.

After a few flashes of the red light, it turned into a green light. Xu Yuntian smiled and whispered to Yan Xiaoyu and Yang Feng: "I have freezed the wireless pinhole camera. The surveillance people can only see the scene where no one just now. The time is only one minute. We must pass the camera surveillance area within one minute."

Yan Xiaoyu and Yang Feng nodded together, followed Xu Yuntian and ran quickly. The three of them walked out of the camera surveillance area in less than 30 seconds.

After the three of them left the camera surveillance area, they quickly hid behind the big tree and slowly approached the secret sentry area. There were secret sentry on the trees 300 meters ahead.

Xu Yuntian took out the telescope. He saw the secret whistle at three o'clock and was checking with the telescope. He immediately made a hidden gesture. Yan Xiaoyu and Yang Feng immediately hid close to the tree.

"There are six secret whistles in total. We must kill them at the same time, two of them each, and act according to the agreed plan." Xu Yuntian whispered to Yan Xiaoyu and Yang Feng.

Yan Xiaoyu and Yang Feng nodded together, and the three of them acted separately. Each of them had two targets. First, they quietly arrived at the best attack location, and then launched an attack at the same time.

About three minutes later, Xu Yuntian, Yan Xiaoyu and Yang Feng reached the best attack point. Xu Yuntian stretched out three fingers, meaning that an attack was launched immediately after three seconds.

The three of them silently recited three times in their hearts, and then the three of them launched an attack at the same time. Xu Yuntian shook his hand and two toothpicks shot out.

The toothpick shot the secret whistle at one o'clock and three o'clock. The two of them were penetrated by the toothpicks almost at the same time. They groaned and fell from the tree.

Yan Xiaoyu fired crossbow arrows, and two crossbow arrows shot through the throats of the two secret whistles, and the two secret whistles fell under the tree together.

Yang Feng fired a flying knife, and the two flying knives penetrated the necks of the two men's secret whistles. They covered their necks with their hands and planted them under the tree together.

In an instant, six secret whistles were killed. Xu Yuntian, Yan Xiaoyu and Yang Feng stretched out their fingers and made a victory gesture, and the three of them smiled.

Further ahead is the far infrared protection area. The three of them seized a sniper rifle equipped with a muffler from the secret whistle, continued to move forward, and stopped about ten meters away from the far infrared protection area.

Xu Yuntian observed for a while and soon found a vulnerability in the far infrared protection system. This vulnerability is that after electronic interference, the far infrared space will appear.

Xu Yuntian took out the matchbox size thing, pulled out the antenna, pressed the button, and after the red light flashed, he pressed the button again, and the red light flashed and turned into a green light.

A space zone appeared in a corner of the far infrared in the distance. There was no far infrared sensing in that small area, and the three of them quickly passed through the far infrared protection network.

"Okay, after walking for a while, there should be a cave in front of you. There should be an ancient tomb inside the cave. The secret base of the Crow Gate is inside the ancient tomb." Xu Yuntiandao.

"Brother Tian, ​​the protection of the cave must be very strict. There must be many cameras in the cave. How can we get in?" Yan Xiaoyu frowned.

Xu Yuntian shook his head and said, "I don't know how to get into the ancient tomb at the moment. Only after we arrived near the cave and reconnaissance the situation on the scene did we know how to get into the cave."

"If it really doesn't work, the three of us will kill us!" Yang Feng said with a sniper rifle.

"There is definitely not a strong attack. There are probably at least five or six hundred people in the ancient tomb. Just relying on the three of us to attack, that's not asking for death!" Xu Yuntian shook his head and said.

Ten minutes later, Xu Yuntian, Yan Xiaoyu and Yang Feng appeared near the cave. The cave was very hidden. The entrance of the cave was surrounded by green vines. If you didn't look carefully, you wouldn't be able to find that it was a cave.
Chapter completed!
