Knowing that this would be the most comfortable year they had in the barracks, the officers and soldiers also cherished it.

Therefore, when the county town where the station is located on the third day of the Lunar New Year fell into the atmosphere of changing relatives, people traveling to and from the national highway saw the officers and soldiers sitting on troop carriers heading to the railway station with the same smiles on their faces.

At this time, the Spring Festival fell into a rare underestimation, so that the coordinated high-speed rail was smooth all the way, and after a day, the high-speed rail was transferred to the train, and after another day and two nights, it was transferred to road transportation.

On the way, Shen Yun joked that if there was another donkey cart or bicycle at this time, they would be able to sit all over the land vehicles.

Heading south along National Highway 219, the deserted Gobi Desert is covered with snow. When I looked up, it was a blue sky, but when I looked down, I was blinded by the sunlight reflected by the snow.

After entering National Highway 219, the further south you go, the higher the altitude. At the beginning, there was no obvious feeling of more than 100 kilometers, but after reaching the section of National Highway 219 and Xu Jie Dwarf Aili fork, the altitude has risen significantly.

As the air gradually thinned, Shen Yun could already clearly feel that there was something strange when he breathed.

"Attention units, report your situation, if anyone is unwell. Be sure to tell the fighters and report it immediately. ”

Under such conditions, we must not play falsely, and it is also not the time to carry forward the spirit. If you feel unwell, you will report it, this is something that Shen Yun has repeatedly ordered since he turned into National Highway 219.

"Armored company, all normal."

"Second armored company, normal."

"In the third armored company, two fighters are feeling unwell, they have taken medication, their condition is improving, and they can continue to advance."

……

Although they had been trained before, there were still fighters who were unwell, which was expected by Shen Yun.

The final statistics showed that eleven soldiers had taken the medicine, Shen Yun thought about it, and decided to stop and rest for a while.

"All of them, stop and rest. Pay attention to let the fighters replenish their energy, the next section of the road will continue to climb in elevation, the highest point will reach 5,000 meters, from now on, it is a height that we have never challenged, we must pay attention to our own safety. ”

How many years before that, Shen Yun had never raised the issue of safety on the march like he did now.

But now it is really different, although after arriving in Wushi, the troops once again carried out a very strict physical examination, but it is difficult to guarantee what will happen to the soldiers under the plateau climate.

Seeing the vehicle slowly stop, Shen Yun came to the vehicle of the military doctor accompanying the team.

"Doctor Gao, I'm going to trouble you next."

There were a total of six people sitting in the vehicle, all of whom were the backbone of the war zone from the nearest frontier army hospital, and Dr. Gao was their leader.

Of course, Dr. Gao knew what Shen Yun's request was, and speaking of which, he really admired the deputy regiment-level battalion commander in front of him.

From the time they were transferred to the team to the present, this is the first time that Shen Yun has asked them to come down to work. But the location chosen, I have to say, is indeed very old-fashioned.

The current altitude is about 3,800 meters, which is just the height at which the body begins to adjust for this unit from the foot of the Qilian Mountain. Measuring blood pressure in this place is a good way to analyze each person's ability to adapt to high altitudes.

Nodding, the six doctors each got out of the car with an aluminum alloy box and walked to a different company.

Measuring blood pressure on a plateau, especially if the altitude is changing, is best done with a mercury monitor.

Experienced Dr. Gao once did experiments with the team, and when the very advanced electronic sphygmomanometer and mercury sphygmomanometer were measured in different areas, the electronic sphygmomanometer always had deviations, and the reason could not be found.

Although in a fixed area, this deviation can be corrected to obtain accurate data, but it is very troublesome to do so on the march.

And the kind of electronic sphygmomanometer commonly equipped by the military, even after the altitude exceeds 3,000 meters, it will repeatedly indicate that the strap is not tightened.

On the other hand, although there will be problems due to air infiltration into the mercury column, as long as it is simply repaired, it can continue to be used, and the time taken by each person to measure is definitely less than that of an electronic blood pressure monitor.

Because of this, the aluminum alloy box contains all mercury blood pressure monitors.

After two hours of cooking in a pressure cooker, the doctors' work was over.

Shen Yun, who was worried about the physical condition of the soldiers, followed Dr. Gao until he saw that Dr. Gao had obtained the final data summary, and then he cautiously asked:

"Doctor Gao, there's nothing wrong with the soldiers, right?"

It is certain that there is a problem, but as long as there is no fatal problem, Shen Yun can accept it.

Hearing Shen Yun's inquiry, Dr. Gao smiled and nodded:

"It seems that Camp Chief Shen is also half an expert, and he knows that it is impossible not to have problems in this situation. That's right, the fighters are now generally in a stress response to a low-oxygen environment. Some fighters reacted more severely, but after taking Rhodiola rosea, they were able to overcome the more severe environment that followed. ”

Shen Yun nodded, but did not make any more decisions in front of Dr. Gao.

After letting the soldiers rest for a while and look at the slightly recovered state, Shen Yun began to inform the vehicles to rest for two hours every two hundred meters above sea level, and then the team began to move forward again.

The difference in altitude of 200 meters may take a long distance in the plains, but on National Highway 219, it is only less than two kilometers.

It felt like the car had just started and then stopped again.

However, if the soldiers were to walk these two kilometers on their own, they might not be able to walk for an hour.

From here to the highest point, it takes six repairs, although the entire journey takes less than an hour.

It took half a day, until it was completely dark, and Shen Yun and his party could only reach an altitude of 4,600 meters, and it would take a long time to officially pass the height that was enough to make people lose their lives.

Under the dark canopy, in the light of a long series of car lights, watching the soldiers receive blood pressure measurements again, Shen Yun's heart was full of emotion.

Before coming to the plateau, he looked up a lot of information.

In medicine, 5,000 meters is a watershed, generally speaking, 5,000 meters is the maximum height that people can live in for a long time, and then up, it is called the forbidden area of life.

However, there are some people who have broken through the so-called forbidden zone of life and put down roots at a height of 5,380 meters.

is also a soldier, Shen Yun really wants to see those heroes who put their lives above authority this time.
