All the women were startled, and they all stopped, looking at Ye Beichen, waiting for his answer, and I also looked at him curiously.

"The foot is the most peripheral part of the blood vessel branch, the fat layer is thin, the heat retention is poor, the skin temperature of the sole of the foot is the lowest temperature of the whole body, in summer, if the feet are often washed with cold water, the feet will be further cold and cold, and then through the blood vessels conduction and cause a series of complex pathological reactions throughout the body, which may eventually lead to various diseases. Ye Beichen said seriously.

"Is that an exaggeration? Xia He said.

"The sweat glands on the soles of the feet are more developed, walking more in summer, sweating a lot, at this time, if you suddenly wash your feet with cold water, the pores will suddenly close and block, and the sensory nerve endings of the feet are stimulated by cold water, and the normal functioning of the vascular tissue will shrink violently, which may lead to vasodilation dysfunction, induce acral artery spasm, and cause a series of diseases, such as erythromelalgia, arthritis and rheumatism, not to mention, the temperature here is much higher than the summer we know, and the above problems will be more obvious. Ye Beichen said.

"I should be fine if I go down to the bubbles, right?" Xia He asked, but his voice was obviously hesitant.

"Don't you see these animals are hot? Why don't they go down? Even animals know how to protect themselves, don't you know?" Ye Beichen said.

This time Xia He stopped talking, and the girls also stopped the urge to go into the water, and walked back to the road again, Xia He looked at the river for a while, and had to follow us silently.

"I didn't expect you to be so knowledgeable. I said with a smile.

"It's just some necessary survival knowledge, and we need to learn it every day, but it's just that what we learn is different from yours. Ye Beichen said.

Ye Beichen's words completely broke my understanding of mercenaries, and after getting along with each other during this time, I knew that mercenaries are not what they do in the movie, they can only kill people, and there is too much professional knowledge behind this.

And their ability to survive in the wild is really strong, and my tricks are like heaven and earth compared to him.

"If you are too hot, you can eat this fruit and it will have the effect of cooling off. Ye Beichen pointed to the red fruits on the cactus and said.

"I'll try it. As I spoke, I reached out and picked it up.

But I saw Ye Beichen laughing on the side, and before I could figure out what his smile meant, I was stabbed in the hand.

"You didn't say it earlier. I said angrily.

"There are so many thorns, you can't see them. Ye Beichen said with a smile.

With my sign, everyone was much more careful, carefully removing the thorns on the fruit, peeling off the skin and putting it in their mouths.

"Well, sweet and sour, not bad. I took a bite and said.

However, we did not stop to rest, and after eating, we washed our hands in the river and continued walking, because during this time, I still had a full understanding of the physical strength of everyone.

In the afternoon, the surroundings gradually changed, and instead of the endless desert, some boulders began to appear around.

"Let's keep going and see if we can find a suitable place to spend the night. I said to the crowd.

This time, everyone dared to complain again, because before everyone set off, Ye Beichen had explained to them how terrifying the night in the desert was.

The appearance of boulders is becoming more and more frequent, and some scattered dead branches have begun to appear on the ground, and even a lot of tumbleweeds, but the temperature is still very high.

In the afternoon, the cacti on both sides of the river also began to change a little, the branches and leaves became more slender, and the fruit on it became more vivid.

"Why does this fruit look familiar to me?" I asked, pointing to the fruit.

"Isn't this the dragon fruit you usually eat? Ye Beichen said.

This time everyone was excited, as soon as we stopped, the horned zebra took the initiative to come forward and eat it, and when we saw the horned zebra eating, it must be not poisonous.

"Bring some to eat on the road and don't stay too long. I said to the crowd.

The girls were excited to pick, and I took this opportunity to go to the river to wash my face, drink some water, and let the horned zebra replenish some physical strength by the way.

Everyone was in a much better mood when we hit the road again, and we finally found a place to stay before dark.

There is a stone mountain not far from the river, which is about ten meters high, standing in the sea of sand, and this stone mountain is hollow inside, through the entrance more than one person wide, the space inside is enough for us to settle.

"Well, finally there is a place to stay, let's gather some firewood. I said and began to prepare for the fire.

In fact, along the way, just in case, we not only brought firewood, but also picked up some along the way, and now it seems that there is no need to worry about firewood at all.

However, in line with the principle of preparedness, it is better to be more prepared.

The firelight illuminates the environment inside the cave, and with fire and light, everyone's mood is much better, maybe in the wild, fire can give humans some sense of security.

"You guys are going to eat, Ye Beichen and I will go and take a look at the surrounding environment. I said, standing up and walking outside.

In fact, this is also what Ye Beichen meant, after all, we are going to spend the night here, but we are in a hurry, if there are any large animals around, it will be dangerous at night.

The two of us carried torches and walked along the stone mountain, but for the time being there was no sign of any animals, by this time it was already dark, the temperature around us plummeted, and we walked towards the entrance of the stone mountain.

Unexpectedly, John and Paul were not idle, and used the wood we brought with us to defend the entrance to the cave, and when they saw us returning, they hurriedly moved them away.

"I guess there shouldn't be any problem. Ye Beichen said.

"Then we'll spend the night here tonight, and now we can't go anywhere else. I said.

"But be careful, I always feel that something is wrong. Ye Beichen said.

"Then rest in batches, and divide into two groups of people, one group of people to watch the first half of the night, and one group of people to watch the second half of the night. I said.

"It's okay, after all, we don't know this place well, and if there are more people, we can deal with anything. Ye Beichen said.

"Hurry up, everyone, and after eating, we will rest in two groups. I said to the women.

"Isn't it usually just two people? Xia He said.

"There's something wrong in this place, it's safer with more people. I said.

"Oh...," Xia He replied in a low voice.

Everyone ate some dragon fruit and dried meat on the way, the temperature was very low at this time, although they were in a hurry to rest, but they still couldn't slack off their bodies.

We still boiled some jerky in the pot, because the temperature plummeted, everyone had already taken out our equipment for crossing the snowy mountains, and after settling down the beds, I let a few women with average strength go to rest.

As for the four of us, Paul and I took a few women to keep watch for the first half of the night, and Ye Beichen took John and a few women to keep watch for the first half of the night.

Soon the voices of the crowd came, along the way, our psychological quality has changed a lot, anyway, we should eat, sleep, nothing is more important than saving physical strength.

Fortunately, nothing unusual happened in the first half of the night, and after the changing of the guard, we slept until dawn, and this place was good as a temporary shelter, but this was only at night, and the heat in the cave during the day was not at all.

"Alright, let's move on, hopefully we'll find a suitable place to settle before dark. I said to the crowd.

After walking along the river for half a day, the surrounding vegetation began to increase and the temperature also dropped, which is a good sign, which indicates that the environment ahead should be good.

"Everybody stop and drink some water, eat something and take a break. I said to the crowd.

"Lead the foot zebra to the river to drink some water. I said.

After the horned zebra drank enough water, and we also replenished some water ourselves, I came to Ye Beichen and stood still.

"Beichen, let's go to the front to see the situation. I continued.

"Good. Ye Beichen said and jumped on a horned zebra.

"Blackface, you scream at any danger if you stay here. I said to the black face.

After saying that, I also jumped on a group of horned zebras, and the two of them rode their horses and whipped forward, galloping forward.

This horned zebra hasn't run for a long time, and it's very exciting to run now, and its speed has naturally increased a lot.

The vegetation along the way gradually became denser, stretching along the river face towards the desert, but the vegetation was not so tall that it was blocked by the sand dunes, so we could not see it in the distance.

But just as we were about to explore a little further, a black-faced wolf howled behind us.
