In areas where the body cannot digest such high oxygen content, it will cause symptoms such as fatigue, weakness, drowsiness, chest tightness, dizziness, diarrhea, etc., just like being drunk.

This is relatively mild. In severe cases, symptoms such as decreased hemoglobin content, slow heart rate, increased cardiac output and blood volume, and reversal of pulmonary hypertension may occur, which are very painful.

Among all the people in the Tiger Brigade, Zhuang Yan and Li Zheng were the most relaxed.

After all, they have received plateau combat training and have even participated in missions in such high-altitude areas, so they have long adapted to the environment and altitude here.

Although this is a snow-capped mountain and it is very cold, it is not a problem for them. Their strong physiques can quickly regulate their breathing, the muscles of the whole body relax rhythmically, the center of gravity moves slightly forward, and the posture is slightly lowered. There is no problem at all.

When passing through the middle slope of the ridgeline, a strong wind blew over, and the clouds of snow powder hit everyone like bullets, making a crackling sound. Many people almost fell to the ground and hurriedly squatted down in fear.

He didn't dare to move even half a step.

On the other hand, the members of the 270th Squadron didn't take it seriously at all.

They were accustomed to violent winds. They just adjusted their center of gravity slightly and still moved forward rhythmically in the confusing wind and snow.

This is where the plateau special forces specialize. No one knows this place better than them, and no one knows the snow-covered plateau better than they do.

This is their territory, and they are the gods here.

Finally, the mountain wind finally passed, and everyone climbed through this difficult and dangerous journey in one go.

Zhao Chuan stopped on a relatively gentle hillside and announced a five-minute rest.

He came to Qi Sheng and Li Zheng and pointed towards the distance.

"Do you see it?"

Li Zheng and Qi Sheng looked in the direction of his finger.

Zhao Chuan looked proud, pointed to the distance and said: "There! That's the border, and this is where we guard. Do you know why we often come here to climb this mountain? Every time we pass here, we stay for a few minutes.

Look at the view here."

Suddenly, an eagle's cry came from beneath my feet.

Everyone lowered their heads and looked into the distance.

I saw an eagle spreading its wings and breaking through the sky, flying over the snow-capped mountains shining with silvery white light, and hovering over this uninhabited snowfield.

Standing on the top of the snow-capped mountains, looking at the white clouds lingering among the mountains, everyone feels an inexplicable shock deep in their hearts.

This is the country.

the land of one’s own motherland.

So beautiful and so majestic.

Perhaps before I came here, guarding the border and guarding the country were just concepts in my mind.

When you actually come here, see the border, and see the land here, all the concepts of protecting the country will be most concrete, and you will be able to feel why the border guards have no regrets, and understand them

The kind of person who is willing to give and be lonely, spending his most precious youth on this uninhabited snowy plateau.
