Everyone knows that the higher the altitude, the stronger the wind. Especially for high-altitude peaks among mountains, the peaks are usually areas where turbulence converges. The air currents rising from the valleys often converge at the peaks, causing more severe turbulence at the peaks.

This is also why when people climb a mountain, they often feel the wind getting stronger after reaching the top, and the wind direction blows to the east sometimes and to the west sometimes, without a fixed wind direction. This is actually caused by the typical convergence of air turbulence.

Fortunately, it had just rained today, and the sun was blocked by heavy clouds, resulting in no sunlight in this area, which caused a lot of turbulence in the valley. If it was a sunny day, not to mention Chris, even if Armstrong came, he would not dare to fly a helicopter to land on the peak of a high-altitude mountain.

The sun's radiation can accelerate the flow of air, especially when some places have sunlight while other places are blocked by mountains. This will make the air in the valleys around the mountains heated unevenly. The unevenly hot and cold air will move quickly, often leading to instantaneous strong airflows.

As for the top of the mountain, it will be shrouded by turbulence in various directions, so on a sunny day, it is best not to land a helicopter on the top of the mountain, as it is very dangerous.

Chris tried hard to control the helicopter, and finally landed successfully in the designated area without any danger. However, both Chris and the others in the helicopter broke out in cold sweats.

Yang Jing had never experienced such a thing before. He even felt a little regretful. After getting off the helicopter, he decided never to give such an order again.

Although the place where the helicopter landed was not the highest point of the mountain, it was not far away. Yang Jing did not care about other people. He ran a few steps and finally arrived at the highest point he had just seen.

About a thousand meters down from here is the bottom of a valley. The location where the light was spotted just now is a little bit down the steep slope, about four hundred meters from the bottom of the valley.

The mountain is in the shape of a four-sided pyramid. The slopes on the north, east and west sides are relatively gentle, but the slope on the south side is very steep. Yang Jing estimated that the slope is at least 70 degrees. This steep slope is almost vertical. Others, even many animals, probably cannot climb up this slope.

There are many plants growing tenaciously on the hillside, and I am afraid that they will cover the entire hillside.

Liu Zhaoming and Guo Xiang ran over breathlessly. As soon as Guo Xiang arrived here, he shouted, "My old Yang, why are you landing here? Do you want to experience the feeling of being on top of the world? But it's not right to experience it here. At least you have to go to the peak of the mountain to the west to experience it. That mountain is much higher than this mountain..."

Before she could finish her words, Guo Xiang was startled by the steep slope in front of her. "Fuck, why is this cliff so steep? My legs are weak..."

The seventy-degree slope can be regarded as a cliff. No wonder Guo Xiang was scared. This guy has a slight fear of heights.

Liu Zhaoming was holding a tablet in his hand. He first glanced at Yang Jing thoughtfully, then looked around, especially in the direction of Porgera, and then asked, "Director Yang, is this place..."

Yang Jing nodded slightly and asked, "Teacher Liu, if we were to survey or even mine at a height of about 400 meters below this steep slope, would it be technically difficult?"

Liu Zhaoming immediately became alert when he heard this, and asked in a loud voice: "Mr. Yang, did you see anything here?" Yang Jing's ancestral "Great Qi-Watching Technique" was promoted by Guo Dabao, and almost all the people who came to Papua New Guinea knew about it. At first, geological experts like Liu Zhaoming were still dismissive of this so-called "Great Qi-Watching Technique". They were all highly educated intellectuals and firm materialists, so they naturally would not believe in this mess.

But when Yang Jing asked Liu Zhaoming very confidently whether there was any way to survey or even mine on the steep slope below, Liu Zhaoming didn't know why, but he believed in Yang Jing's "Great Qi-Watching Technique" for no reason.

PS: I would like to thank "Gang38" for the reward of 100.
