"Good luck, mu. I'll see you at the summit."

"Mu, it is estimated that you will be slower than us. After we withdraw, we will leave directly. Later, you will come to Ruidian and I will introduce some friends to you."

"Boy, be careful on the mountain. Don't lose your life. I'll make coffee. You can try it when you come down."

……

On the day when he was ready to go up the mountain, Chen Mu's friends all hugged him and said a few words of blessing before letting him go.

During the window period, in addition to their climbing team, other mountaineering teams also need to seize the time to go up the mountain. However, due to the different routes of each other, they can't see when climbing, and the climbing time may be different.

At zahel's command, everyone set out.

In the concept of many people, mountaineering is to climb up to the top and succeed.

But in fact, mountaineering is a sawing process. Before getting the window period, you have to constantly climb up the mountain to adapt to the climbing rhythm, and then wait until the window period to formally go up.

In the process of climbing, we will complete the climbing task step by step according to the climbing plan made by our predecessors, and settle down in the fixed camp every day, just as if we have made a combat plan and completed it step by step.

There are five sections of the route, each with a fixed camp.

That is to say, when they went up the mountain, they were always in front of each other and cooperated with each other quite well.

Peng cuozhaxi was supposed to be with Chen mu, but when he saw Chen Mu's initiative, he didn't insist.

"It's cold!"

Two people ate something hot, and then each of them got into their sleeping bags and let their bodies shrink in it.

Even if there is a tent to block the wind, but still feel cold.

Zhang Jiahui's eyes closed as he spoke.

Today's journey was not slow. He was a little tired. As soon as his body touched the ground, he fell asleep.

Chen Mu didn't feel how tired he was. He summoned the map and looked at it again.

The key point of the map line should be that Chen Mu was not tired. He called out the map to check it, and went to bed after eating.

Several guides and assistants sat together to discuss the schedule for tomorrow. Duojiwangdui said: "the situation of customers No.1 and No.3 is not very good. Tomorrow they will go to 7000 meters. They may start to give oxygen."

Mountaineering teams have been pulling oxygen bottles, which are usually used on the last day when they rush to the top, then suck enough itch at the top of the mountain, and then withdraw.

However, because this is a commercial mountaineering team, the situation is not the same. Several assistants in the team come to carry oxygen cylinders, and in case of any problems of the customers, they can also assign people to take care of them.

So, they have a lot of oxygen.

Zaher frowned and asked, "is it too early to give oxygen now?"

Dojiwangdui shook his head: "it's late. Today, guest No. 1 has mentioned it to me. He said that he couldn't breathe and wanted to take some oxygen. I didn't agree. I just advised him to rely on himself as much as possible, otherwise it would be more difficult later. He complained a little."

After a slight pause, he said: "he likes to complain. In order to avoid any unpleasant things in the team, try to satisfy him."

In this way, no one else spoke.

Since it's a business, customers always give priority to it.

From duojiwangdui and pengcuozhaxi, they also asked mani and Chen Mu whether they wanted to do so. Chen Mu certainly would not. Manni thought about it, but she didn't want it. Her reason was that she hoped to stick to it as much as possible and achieve anaerobic mountaineering.

In the mountaineering industry, there have been some people who think that anaerobic mountaineering is the real mountaineering, and the modern popular mountaineering with oxygen bottle is not mountaineering.

Therefore, there are a lot of people who really love mountaineering, will try to use less oxygen bottles.

Manny obviously had that idea.

Camping at an altitude of 7200 meters will not only impose a burden on the body, but also make it extremely difficult to breathe. No matter how much you breathe in, it seems that you can't breathe anything.

What's more, the solar radiation here is getting worse.

Before, because there are a lot of dust blocking, the sun's sunshine on people is very comfortable and warm.

But at this time, it becomes different, it is a little burning on the body, people only feel hot, exposed skin is easy to be sunburnt.

The fourth day, finally arrived at the fourth camp.

Chen Mu stood on the side of the camp, looking at the crack in the ice below. He said nothing for a long time.

"Help me, help me, help me..."

Ears, as if to hear a sound of whispering, with a prayer, there are temptations

Chen Mu doesn't know if he hears things by himself, but he knows that the sound comes from the deep of this obscure crevice.

It seems that he is the only one who can hear.
