It stands to reason that for every kilometer of altitude gained, the temperature drops by about 6.5 degrees.

In medical terms, different altitudes will bring different damage to the body. The altitude of more than 5,000 meters has been defined as the highest altitude and is a forbidden area for life. If it exceeds 7,000 meters, it will directly become a mountain death zone!

At this time, the tactical group was training in the forbidden area of life at an altitude of more than 5,000 meters.

Snowflakes kept falling in the slowly gloomy sky, and these snowflakes were actually some tiny ice slags, which could still feel a tingling pain when they hit people's faces under the blowing of the wind.

With the passage of time, every member of the tactical team had to constantly adjust their breathing because of the increasing altitude while enduring the cold weather of more than ten or twenty degrees below zero.

Another important problem is that as early as half an hour ago, the members of the tactical team found that the water in the kettle they were carrying had been frozen into ice cubes.

After breaking the ice cubes in the kettle, the seven members of a tactical team went down one by one, and hurried to eat the ice cubes poured out of the kettle, because it didn't take long for the broken ice cubes in the kettle to solidify again.

In the weather of more than 20 degrees below zero, the tacticians, whose lips were slightly purple from the cold, bit the ice cubes into their mouths, then crushed them, turned the ice cubes into water in their mouths, and then swallowed them in their stomachs.

If you are in the desert training camp, facing the weather in the 40s, several members of the tactical team enjoy it very much. But here, such a feeling can definitely make you want to die.

With the passage of time, the team of tactical teams that were originally lined up in a row gradually began to lengthen, and the distance that was originally less than ten meters was stretched to the current dozens of meters, and the speed at which they traveled became slower and slower.

I don't know when, the pickup truck that was originally leading the way in front suddenly reduced its speed, and in the eyes of Nalan Jun, who was running first, Nalan Jun was extremely angry, the off-road vehicle drove next to him, and then maintained the speed of the car according to the speed of Nalan Jun's running.

"Want to drink?"

In the body, Luo Xueqin, who didn't know where to find a thermos flask, immediately poured a cup of steaming instant coffee from the thermos. Luo Xueqin, who was talking, delivered the coffee to Nalan Jun's side.

"Gollum!"

Feeling the aroma of instant coffee, Nalan Jun, who was a little unlucky, swallowed a mouthful of saliva fiercely, and Nalan Jun, who was only staring at the coffee, had a trace of longing in his eyes.

"Goo-dong!"

Seeing this, Luo Xueqin did not hesitate at all, and she took a sip of the coffee when she withdrew her hand.

Ignoring the other party, she patted the roof of the car, and as the speed of the car decreased again, the pickup truck carried Luo Xueqin and slowly distanced herself from Nalan Jun, leaving only Nalan Jun with a complicated expression, but could only obediently continue to run forward.

Following behind the Nalan Army was Jiang Chen, the leader of the tactical team, and Jiang Chen, who was jogging forward, was panting heavily, and the water vapor spit out of his mouth quickly condensed in the air, turning into a cloud of mist, and then dissipating into the air.

"Want to take a puff?"

After the pickup truck approached Jiang Chen, Luo Xueqin, who took out a bottle of oxygen bottle, put the mouth of the oxygen bottle in front of Jiang Chen, and then slowly opened the oxygen bottle.

"Whew...."

With the sound of gas gushing out, Jiang Chen suddenly felt a clear breath of oxygen inhaled into his nose, but before Jiang Chen could savor this wonderful feeling, Luo Xueqin turned her head and took away the oxygen bottle in front of Jiang Chen.

Luo Xueqin, who brought the oxygen bottle in front of her, took a few greedy breaths, and after seeing Jiang Chen's expression, Luo Xueqin opened her mouth and said, "As long as you apologize to me, this bottle of things will be yours!"

Of course, Jiang Chen knew what Luo Xueqin's apology meant, at that time, when Luo Xueqin took the initiative to lower his speed, finally controlled the speed of the car, and led the tactical team to continue to set off at a uniform speed, Jiang Chen saw Luo Xueqin's extremely gloomy face, and Jiang Chen at that time had already guessed that the other party might retaliate.

"This is definitely revenge!" Looking at Luo Xueqin, who was talking and inhaling oxygen at the same time, Jiang Chen, who gritted his teeth, scolded in his heart.

Jiang Chen also knew that even if he said those three words and apologized to the other party, it was impossible for the oxygen bottle in the other party's hand to be handed over to him, and the final result would only be in vain.

No matter what, of course, Jiang Chen, who would not apologize, snorted coldly, and then gritted his teeth while gradually speeding up the pace under his feet, and slowly widened the distance between him and Luo Xueqin.

"It's boring, let's go and tease the next rabbit cub!" Seeing this, Luo Xueqin muttered, patting the roof of the car and signaling Xue San to continue to reduce the speed of the car, and then began to approach the next team member.

In the following time, the pickup truck driven by Xue San kept moving back and forth between the seven team members, and Luo Xueqin, who was standing on the body, also continued to tempt every member of the tactical team, and its most important purpose was to interfere with a few team members.

Seeing this, although the members of the tactical team gritted their teeth with hatred in their hearts, they could only press the atmosphere and continue to move forward.

I don't know how long I ran, but the Nalan Army, who was running first, suddenly smelled a smell of barbecue meat from the air, and the thick aroma of meat blew from a distance along the wind, and the next second Nalan Army directly drooled.

"Wori, I can't be hysterical, how can there be a smell of barbecue here!" Nalan Jun swallowed his saliva while greedily breathing in the smell of barbecue in the air.

However, no matter how Nalan Jun shook his head and even began to pinch the meat on his arm, the smell of barbecue in the air did not dissipate, but became stronger and stronger!

At this time, the other members of the tactical team who followed behind also smelled the smell of barbecue in the air, and some of the team members and Nalan Jun's thoughts felt that they were dreaming.

However, Luo Xueqin, the only one who knew what was going on, turned her head and followed the direction of the team, and after vaguely seeing the familiar pickup truck a few kilometers away, on a small hillside, she patted the roof of the car and quickly signaled Xue San to speed up.

Immediately, in the surprised expressions of the members of the tactical team, the pickup truck, which had accelerated sharply, quickly overtook them and drove off into the distance.

"Brothers, what are you still doing, we're almost there, there's barbecue waiting for us!"

In the tactical team, Jiang Chen, who was the first to notice a car vaguely parked on a small hillside in the distance and a figure flashing next to him, after thinking of the pickup truck that was speeding away, he was the first to react while speaking, and ran hard with his last strength.

The other team members who heard this also reacted, and several people who were hula gasped for breath while struggling to speed up, chasing the pickup truck, and all the team members had excited expressions on their faces.

Although the tactical team, which had long been exhausted, ran hard, the speed at which they were not moving was actually fast, and it was only on the basis of trotting, and it was just a little faster....

Compared with the tactical team that ran on two legs, Luo Xueqin, who was sitting in a pickup truck, quickly followed the smell of barbecue and arrived at the place of the incident!

"Captain!"

In the open field, next to the familiar pickup truck, there were more than a dozen large and small boxes, all of which were covered with notes indicating what was inside the boxes.

On the ground on the side, there are many special methane gas tanks the size of a human head, several of which are connected to hoses and spray guns, and several spray guns are erected on the ground.

At this time, several spray guns were spraying flames continuously, and the roast whole sheep placed on the spray guns had been roasted golden brown. Assistant Coach Xue Yi, who greeted Luo Xueqin just now, kept turning the roast whole sheep while talking, while Assistant Coach Xue Er kept smearing sauce on it.

"Not bad!" Looking at the roast whole sheep that was constantly bubbling out with grease, Luo Xueqin, who jumped out of the car, swallowed her saliva and said, "The supplies are all right?"

"The materials and weapons and equipment we applied for have been sent by the higher authorities!" Seeing this, Assistant Teacher Xueyi replied.

After answering Luo Xueqin's question, Xue Yi saw that only Luo Xueqin and Xue San had come over, and Xue Yi, who didn't see the figure of the tactical team, asked, "Captain, what about those little guys?"

"In the back!" Luo Xueqin, who spoke, took the sauce from Xue Er's hand and spread the sauce evenly on the roasted whole sheep.

I have to say that roasting whole sheep in the plateau area at an altitude of more than 5,000 meters is indeed a pleasure, and several spray guns continue to provide flames, while roasting and roasting whole sheep, it also brings bursts of warmth to several people.

After Xue Yi heard this, he turned his head and followed the direction of the pickup truck, and after seeing the tactical team that was struggling to run this way, the corners of Xue Yi's mouth twitched slightly.

He finally knew why it took less than an hour for him to get here, but it took more than three hours for his captain to get here, and it turned out that the reason was here.

Assistant Coach Xue Yi finally knew why his captain put the pick-up location here, and she carefully arranged all this, it turned out to be to test the ability of the tactical team, and also to train them.

Although the material receiving site is only more than 20 kilometers away from the camp, the altitude of the receiving site is five or six hundred meters higher than that of the camp.

However, don't underestimate the difference in altitude of five or six hundred meters, this distance is not a difference of one or two hundred meters to six or seven hundred meters, but a gap of more than four thousand meters to more than five thousand meters.

Many people who travel to the highlands are only a few hundred meters high, but in the end they will never be able to overcome this gap!

Moreover, in the last two kilometers of the journey, on the last mile, the tactical team needs to climb over a hill with a slope of about 40 degrees and a length of about 200 meters.

However, this hillside, which does not look steep, is in the plateau area at an altitude of more than 5,000 meters, in front of the exhausted members of the tactical team, is the real test for them!
