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

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

Jiang Yanhai and the others have already seen the view opposite the star gate, a Gobi Desert, deserted and uninhabited, very desolate.

The sizes and volumes of the two star gates are exactly the same, except that the original star gate is the base of the Qilian Mountains, while the opposite side of this star gate is the desolate Gobi Desert.

"Advance team, set off." Jiang Yanhai brought his oxygen mask, then waved his hand directly, and then he quickly walked towards the Star Gate. As countless subsequent personnel began to act quickly, Professor Li and the others temporarily made clear the passage because they all knew that the new world was in danger, so their research was not the most critical, the most critical thing was to solve the danger first.

Jiang Yanhai and the others rushed into the Star Gate directly. After rushing into the Star Gate, Jiang Yanhai immediately felt that the surrounding environment, air, etc. were almost no different from the earth. It looked like Erdan said. Only extremely similar civilizations can have such similarities.

However, they still had an oxygen mask on their heads. He knew it was he, but he could not say it in advance.

The place where they appeared at this moment was also a valley of the Gobi Desert and hills, and there were peaks about 100 meters high on both sides of the Star Gate.

"Yang Rui led the highland peaks on the north side of Jiaolong to establish a defense line. Come with He Chenguang." Jiang Yanhai directly rushed to the highland on the south side with He Chenguang and the others. Because the sun was right in front of them, he temporarily regarded this side as the south side.

"yes!"

Jiang Yanhai and the others rushed to different high grounds, and the same was true for Yang Rui and others behind them. In the Star Gate, the second group of scientists and logistics soldiers quickly pulled two thick optical fibers and carried a large signal transmitter at the same time.

The second group of scientists used the instruments in their hands to quickly check the air composition here. A minute later, Jiang Yanhai and his team's ears sounded the base's prompt sound: "Haidongqing, the air here is almost the same as the air composition of the earth. You can breathe directly without toxins."

"Everyone takes off their masks." Jiang Yanhai shouted softly.

Remove the oxygen mask and the oxygen cylinder, and then they speed up the rushing up the hillside.

In less than 3 minutes, Jiang Yanhai and the others climbed up the hill about 100 meters high. When they reached the top of the hill, they rushed up and saw Jiang Yanhai in the distance, and then he was slightly stunned.

"Captain, Great Wall." Li Erniu couldn't help but shout.

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

That's right, you can see the Great Wall above the mountains and cliffs in the distance in front of them. It's too obvious and familiar. All Chinese people can see this thing as soon as they see it.

"But this Great Wall doesn't seem to be 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 the Star Gate. The closest straight line distance to us is about 3,800 meters. In addition, flags are found on the Great Wall. According to these flags, they should be similar to ancient military flags. From this, it can be basically concluded that the world is still in the feudal society." Jiang Yanhai quickly reported.

"The base received it, and the drone will be ready in about 10 minutes." The base's voice sounded.

"clear."

At this moment, countless logistics personnel were quickly building related equipment at their Star Gate. First, they were large-scale signal transmission devices. The first one was built directly near the Star Gate. Then two portable ones were carried out and started to carry them to the north and south sides, that is, the mountain where Jiang Yanhai and the others were located.

These signal transmission devices have antennas and solar cells that allow them to work continuously for about 10 hours.

When the first batch of materials came in, the second batch of materials had already begun to enter. First, they were some large steel frame structures, and then they prepared all types of disguise nets with the specially made next door. Unexpectedly, the one that rushed up in the end was from the Gobi Desert.

Although the Star Gate is 16 meters high, because there are hills on both sides, people on the Great Wall in the distance cannot see the Star Gate behind the hills. After all, this hill is more than 100 meters high.

While these materials came, a truck also drove out directly from the star gate. Behind the truck, there was a drone placed on the truck's ejection frame. The drone could be ejected directly by the truck. Combined with the signal transmitting devices on both sides, it could detect all objects within a radius of 5 kilometers, and its flight altitude could reach about 5,000 meters.

Moreover, its noise is very small and will not alarm people in this world.

When the drone was ready, a soldier rushed towards Jiang Yanhai with a tablet computer. The drone was operated in the truck compartment, and there was a special drone operation room, but the drone picture could be transmitted to the tablet.

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

"The drone is ready to be launched." Jiang Yanhai issued an order directly.

"Yes, the drone is ready to launch, 3, 2, 1!" As the countdown ended, with a dull "bang", the drone was instantly ejected by the ejection device, and then its engine was started and flew directly into the sky.

It did not fly directly to the south, but first flew to the north and then began to climb at a high speed. At the same time, Jiang Yanhai and the others also saw it. The pictures were all the vast Gobi Desert. There were not many plants on the Gobi Desert. It was like hills, with endless hills ranging from one or two hundred meters to several hundred meters, but the height was not very high.

When the drone climbed to a height of six or seven hundred meters, it began to turn and flew to the Great Wall on the south side. However, it did not fly to the highest altitude and maintained an altitude of about 1,000 meters. At this altitude, people below its engine sound could hardly hear it, and it was difficult for people below its volume to notice it.

It is soon to be seen at such a high altitude of less than 4,000 meters.

Soon, the Great Wall appeared on the Great Wall inside Jiang Yanhai's flat plate. The Great Wall was very fast, about five or six meters wide, and there were many strange machines on it. The most important thing was that there were neatly armoured troops on this Great Wall.
