When the new star gate hit the plant wall, everyone noticed that there was no sound or collision. The thick steel plate structure of the steel plant wall was directly like tofu cut by a knife, and the star gate passed through without any sound.

In less than 10 seconds, a new gate stood next to the gate.

And Jiang Yanhai, they have seen the scenery opposite the star gate, a Gobi desert, desolate and uninhabited, very desolate.

The two star gates as like as two peas and a large size, but the opposite of the original star gate is the Qilian Mountains's base of the belly, and the opposite side of the gate is a desolate Gobi wilderness.

"Advance team, let's go." Jiang Yanhai put on his oxygen mask and waved his hand directly. Then he quickly walked to the Stargate. Similarly, countless follow-up personnel began to act quickly. Professor Li and them temporarily gave way, because they all knew that the new world was dangerous, so their research was not the most critical, The most important thing is to solve the danger first.

Jiang Yanhai and others rushed directly into the Stargate. After entering the Stargate, Jiang Yanhai immediately felt that the surrounding environment, air and so on were almost no different from the earth. It looked like what two eggs said. Only very similar civilizations would have such a similar place.

However, they still wear oxygen masks on their heads. He knows it belongs to him, but he can't say it in advance.

The place where they appear at the moment is also a valley of Gobi desert hills, and there are about 100 meters high peaks on both sides of the xingmen.

"Yang Rui led Jiaolong to build a defense line on the highland mountain in the north. He Chenguang, you follow." Jiang Yanhai directly led he Chenguang and they rushed to the highland in the south. Because the sun was right in front of them, they regarded this side as the south side for the time being.

"Yes!"

Jiang Yanhai and others rushed to different heights, and so did Yang Rui and others behind them. In the Stargate, the second batch of scientists and logistics soldiers quickly pulled two thick optical fibers and carried a large signal transmitting device.

The second group of scientists quickly checked the air composition here with the instruments in their hands. A minute later, Jiang Yanhai heard the prompt sound of the base in their ears: "haidongqing, the air composition here is almost the same as that of the earth. You can breathe directly without poison."

"Everyone take off their masks." Jiang Yanhai whispered.

They took off the oxygen mask and oxygen cylinder, and then they accelerated their steps up the hillside.

In less than three minutes, Jiang Yanhai and his team climbed up the hill about 100 meters high. When they reached the top of the hill, Jiang Yanhai saw the distance as soon as they rushed up, and then he was a little stunned.

"Captain, the Great Wall." Li Erniu couldn't help shouting.

"I see." Jiang Yanhai replied, and then picked up the sniper rifle in his hand.

Yes, in front of them, you can see the mountains and cliffs in the distance. There is the Great Wall. It's too obvious and familiar. All Chinese people can see it the first time they see it.

"But the Great Wall doesn't seem very long," Jiang Yanhai added.

At least the Great Wall within their sight is only about ten kilometers.

"Base, we found the Great Wall on the south side of xingmen. The nearest straight-line distance from the Great Wall to us is about 3800 meters. In addition, we found flags on the Great Wall. According to these flags, they should be similar to ancient military flags, so we can basically conclude that the world is still in the feudal social period." Jiang Yanhai reported quickly.

"Received by the base. The UAV will be ready in about 10 minutes." the voice of the base rang.

"I see."

At the moment, countless logistics personnel are rapidly building relevant equipment at the Stargate. The first is a large signal transmission device. The first is directly built near the Stargate, and then two portable ones are lifted out and began to lift over to the north and south sides, that is, the mountain where Jiang Yanhai is on their side.

These signal transmission devices have antennas and solar cells, which can keep them working for about 10 hours.

After the first batch of materials came in, the second batch of materials began to enter. First, some large steel frame structures, and then along with the special next door camouflage net, they prepared all types of camouflage nets. Unexpectedly, it was the Gobi desert.

Although the star gate is 16 meters high, there are hills on both sides, so people on the Great Wall in the distance can't see the star gate behind the hill. After all, the hill is more than 100 meters high.

At the same time when these materials came, a truck opened directly from the star gate. At the back of the truck, a UAV was placed on the truck's ejection rack. The UAV can be directly ejected by the truck. With the signal transmitting devices on both sides, it can detect all objects with a radius of about 5km, It can fly at an altitude of about 5000 meters.

And its noise is very small and won't disturb people in the world.

When the UAV is ready, a soldier has rushed to Jiang Yanhai with a tablet computer. The UAV operation is in the cabin of the truck. There is a special UAV operation room, but the UAV picture can be transmitted to this tablet.

After handing the tablet to Jiang Yanhai, the soldier rushed down again.

"The UAV is ready to launch." Jiang Yanhai directly issued an order.

"Yes, the UAV is ready to launch, 3, 2, 1!" with the end of the countdown, a dull sound of "bang", the UAV was immediately ejected directly by the ejection device, and then its engine has started and flew directly to the sky.

Instead of flying directly to the south, it first flew to the north and then began to climb at a high speed. At the same time, Jiang Yanhai and his colleagues also saw that what came from the picture was the vast Gobi desert. There were not many plants on the Gobi desert. It was like a hill. The hills were continuous, ranging from one or two hundred meters to hundreds of meters, but the height was not very high.

When the UAV climbed to an altitude of 600 or 700 meters, it began to turn and flew to the position of the Great Wall on the south side. However, it did not fly to the highest empty position. It could only maintain a height of 1000 meters. At this height, people under its engine sound could hardly hear, and it was difficult for people under its volume to notice.

Less than 4000 meters away, at such a high altitude, you can see it soon.

Soon, the situation above the Great Wall appeared in Jiang Yanhai's flat plate. The Great Wall was fast, about five or six meters wide, and there were many strange machines on it. The most important thing was that there were neat and uniform troops wearing armor on the Great Wall.
