The nearly vertical Wuzhi climbs up the mountain, and the people in the helicopter hold the handrail tightly. Yan Zhaoming, sitting in the co pilot's seat, scolded, "can't you find a good flight route?"

"I have to cross this mountain!" Ji Tong turned to look at him and said with a smile, "from this road, we can get to Tibet province earlier. The task is urgent. Besides, if I'm here, nothing will happen. "

Yan Zhaoming can see the sound in his eyes with his eyepiece. The two brothers have the same character, and they are all open-minded, but some of them are not annoying. Yan Zhaoming is just worried about whether the military transport plane behind him can cross the mountain.

As the height rises in a straight line, the scene around us is no longer green. All around is a thick layer of mountain fog, visibility is less than tens of meters, flying in such an environment is a test of the pilot's reaction ability.

A little careless will hit the mountain, but sitting in the driver's seat, Ji Tong is a pair of don't care. Everyone knows that his driving skill is very good, but if it is good, no one will use his life to prove that he has good driving skill.

The maximum flying altitude of Wuzhi is 6 km, while the military transport plane behind is a little lower. About 6 km is the limit, and the height of this mountain is 4000 meters.

However, it is located on the second plate, and the absolute level will not be less than 5000 meters. On the military transport plane, he was a pilot transferred from Suzhou air defense forces. His qualification is relatively old. It's been ten years since I flew a plane.

There has never been a mistake, such a height for him should be no problem, as for his brother Ji Bo, let alone. If he is just more open-minded in his heart, then Ji Bai is rampant.

What kind of aircraft in his hands have to carry out a few difficult movements, is willing to give up. Even if it was a civilian helicopter, he estimated that Jibo would dare to take them across the mountain.

The higher the plane goes up, the lower the visibility. Gradually, there was a layer of white fog in front of them. For the sake of safety, Ji Tong asked them to fasten their seat belts and fly all the way. These people didn't fasten their seat belts because they were not in danger.

At the same time, I believe in Ji Tong's technology, but now Ji Tong tells them to fasten their seat belts, and they dare not make fun of their own lives. Wuzhi slowly rises forward and its speed begins to slow down.

This mountain is located in the Middle East of Sichuan and Dali. Jingchu border area. In ancient times, it was called Jianmen. The towering mountains stand on the road leading to the south. Before Qin and Han Dynasties, it was used to resist the invasion of Nanman.

Naturally, in the early days of the founding of the people's Republic of China, Daxing industry cut down a large area of virgin forest here, but for more than ten years, there have been no trees on hundreds of hectares of land here.

Several decades later, avalanches, mudslides and other natural disasters often occur here, and the authorities concerned are aware of the need to harness Jianmen mountain. After more than a decade, they will always restore this place to its original appearance.

Although it's July, the rainfall here is still lasting, and the fog on the mountain also surrounds the top of the mountain all the year round, becoming a landscape here.

Three helicopters walked in front and a transport plane followed. The height of the two gradually climbed to 5000 meters.
