When Yan Shaoxin led his soldiers through the light gate.

Lin Li and others have already vacated a large open space in the camp to avoid trampling accidents due to lack of space after the troops cross.

When the troops arrived one after another, Lin Li stepped forward and stretched out his hand:

"Hello, commander Yan. I'm Lin Li, the person in charge of the firewood camp. This is colonel Lin Ziming, the captain of the special combat brigade next to me."

Yan Shaoxin had done some homework before he came here. Naturally, he knew Lin Li's identity. He politely shook hands with Lin Li:

"Hello, director Lin, I'm Yan Shaoxin. According to the instructions of the General Staff Department, all the actions of our regiment in the foreign world will be subject to your instructions."

Then Yan Shaoxin turned his head and saluted Lin Ziming: "Colonel Lin, let's meet again."

As members of the same garrison system, Yan Shaoxin and Lin Zi had a lot of contacts in the Ming Dynasty.

When the meeting was held a few years ago, the two of them were in the guest house or next door. They had a deep friendship with each other.

Lin Ziming smiled and returned a gift:

"Lao Yan, you've taken a good job this time. Tut Tut, you're the first to set foot in a regimental unit in a different world. I don't know how many people envy you."

Yan Shaoxin crossed his hands in front of his chest and snorted with pride:

"Envy is envy. Who let them stay far away, and they don't have such good soldiers?"

Lin Ziming smiled and patted him on the shoulder. He didn't say anything again.

In fact, Lin Ziming or Yan Shaoxin.

They all know.

This is a different world with extraordinary power.

The so-called "good job" and "envy" are just free and easy jokes among soldiers.

It is true that stepping on a different world represents glory, but it may also represent blood and sacrifice.

Opportunities are always accompanied by risks.

But they still came and were not afraid.

This is the soldier's consciousness.

...........

With the arrival of a large number of materials and personnel, the firewood camp was crowded.

Fortunately, the valley where the camp is located has a wide vertical depth.

According to the arrangement of the headquarters.

The newly arrived soldiers were placed on both sides of the camp, with main battle tanks and armored vehicles parked on the outermost edge.

These chariots not only played a garrison role, but also directly connected to the main road out of the valley.

Both defense and mobility.

Lin Li and others, accompanied by several technicians, came to two ac311a helicopters.

Lin Li stood outside the hatch and looked inside. He turned to a mechanic and asked:

"Master Chen, has the helicopter been debugged?"

The mechanic surnamed Chen from hufei group put the wrench aside, pointed to the flashing light on the dashboard and said:

"The automatic tilter, the total distance control lever and the barometric altimeter have all been checked. Their performance is normal in the world."

Lin Li continued to ask, "the foreign world has not launched satellites, and Beidou Positioning is temporarily useless. What about the navigation of the aircraft?"

The mechanic surnamed Chen pointed to Zeng Gucheng and said with a smile:

"Thanks to director Zeng's team, thanks to the measurement results of the Institute of physics, the Institute of mechanical research is based on the extraterrestrial gravitational constant and other information returned in the first issue.

The accelerometer and gyroscope are re optimized by using the magic cube III supercomputer, and the existing magnetic compass navigation is optimized by using the Kalman filtering algorithm.

In this way, with the vole navigation technology reserved by hufei, the two helicopters can use the inertial navigation system, magnetic compass navigation and vole navigation system at the same time.

Although it can't compare with the accuracy of GPS navigation and there are some risks in long-distance flight, it's easy to fly medium and short distances within 300 kilometers - this range is enough for now. "

Lin Li nodded vaguely.

His expertise is in the field of biology, and physics can only be regarded as half a bucket of water.

But since the mechanic surnamed Chen dared to say so, Zeng Gucheng on the side did not object.

I think there should be no big problem with navigation.

In addition.

As ac311a is a light aircraft, the requirements for takeoff and landing platform are not high.

Lin Li directly arranged people to vacate a large open space at the edge of the valley as a helipad.

After cleaning up the sand and gravel, spread the soil stabilizer, and then spread the special cement up.

In less than five minutes, a clean and stable temporary apron was completed.

Yes, the setting time is less than five minutes.

The special cement used for flood control and embankment consolidation is so unreasonable.

Half an hour later, a message came from the temporary ground service tower built by hufei group:

The VOR navigation system's high-frequency omni-directional beacon has been successfully sent and received, the crew has been in place, and the two ac311a helicopters can start at any time.

Lin immediately issued an order: "two helicopters take off immediately to carry out the exploration mission. The exploration radius is 150 km. In case of emergency, they are allowed to return in advance!"

Dudu Dudu——

The blades of the helicopter whirled at high speed, bringing up a strong wind.

The height of the fuselage stretched slowly, and finally flew out of the valley and gradually disappeared into the sky.

........

As a helicopter pilot, Yao Rong, 44, has a brilliant resume - the chief test pilot of hufei group, the head of the air and space crew of the rescue team, has flown for more than 10000 hours, has participated in many large-scale civilian and official search and rescue missions, and has been commended in the great hall as an excellent representative of the industry.

In the past half of his flying career, Yao Rong almost flew all over the north and south of the river.

I have seen the grandeur of the East China Sea and the grandeur of the plateau.

I've rinsed hot pot in Sichuan Province, rolled youduner in modu, drunk stewed and boiled in DIDU, and eaten people from Fujian Province in Guangdong Province... Ah, no, cooking rice.

Well, cook rice.

In a word, I have walked for several rounds in the southeast and northwest.

But to be honest, flying over the territory of a different world is the first time Yao Rong has seen in decades.

According to the plan of the headquarters, the helicopter piloted by Yao Rong and his partner Yu Guanghui will explore the past all the way along the south, that is, the direction of the city.

"Tower, this is 8633. At present, the flight altitude is 3700 meters, and the straight-line distance from the camp is about 55 kilometers.

The internal dial display is normal and the signal is stable. Does the headquarters have new instructions? "

"8633, this is the tower. There are no new instructions from the headquarters. Please continue flying according to your current position."

"Roger, Roger."

After hanging up the communication, Yu Guanghui turned his head, smiled and said to Yao Rong:

"I don't think so, Lao Yao. We've been partners for most of our lives. We actually have the opportunity to fly in a different world.

My boy likes reading foreign novels best, but it's estimated that this smelly boy can't dream. His father really went to the foreign world when his cat was reading novels under the quilt! "

Yao Rong and Yu Guanghui are similar in age, and their children are of the same generation. They are both in the puberty of secondary two. Wen Yan also said:

"Who's not? My baby also likes to see these. Just two weeks ago, he stole the black strap of my watch and showed it off in school. He said it was a ten thousand year soul ring."

Yao Rong shook his head and sighed:

"Unfortunately, we signed a confidentiality agreement. I'm afraid we can't say anything about the world in our life."

Yu Guanghui grinned. He was more optimistic than his partner

"Not necessarily. The government clearly wants to develop the rhythm of the different world. When the time is right, it may be made public... Eh, Lao Yao, what's that?"

Yao Rong looked at Yu Guanghui's direction.

Next second.

Yao Rong grabbed the communication equipment and almost roared:

"Tower tower, I'm 8633. Abnormalities are found on the ground. A large number of huge monsters are moving towards the city!"
