The group of men walked up, their lips chapped and chapped.

Yang Tongtong and Yang Xinxin also looked at the team, not knowing what they were going to do.

The middle-aged man led by spoke: "In Xia Zhang Qian, I don't know who the two are?" ”

Zhang Qian?

Yang Xinxin didn't know who Zhang Qian was, but Yang Tongtong showed an extremely surprised look.

He heard his father tell this story, saying that Zhang Qian was a diplomat and explorer of the Western Han Dynasty, a "pioneer of the Silk Road" and "the first Chinese to open his eyes to the world."

So this road is the Silk Road?

Yang Tongtong immediately replied: "Uncle Zhang Qian, my name is Yang Tong, and she is my sister Yang Xin." ”

Chinese?

Zhang Qian and the people accompanying him didn't expect that these two strangely dressed people actually spoke Chinese, which shows that they are the sons and daughters of our Han Dynasty.

But the Han Dynasty didn't have such clothes like them, what was going on?

When Zhang Qian was puzzled, Yang Xin asked curiously: "Uncle Zhang Qian, where are you going?" ”

Zhang Qian looked at Yang Tongtong and Yang Xinxin and did not answer this question.

He met two strange children in this strange place, and he would certainly not tell them his purpose.

Coupled with the fact that they had been imprisoned by the Xiongnu for ten years in the past, Zhang Qian was absolutely unwilling to let himself be in danger everywhere.

Zhang Qian thought for a moment and replied, "We have to go to a far place to complete our mission." ”

Yang Xinxin asked, "Uncle Zhang Qian, can you take us with you?" ”

Zhang Qian began to hesitate and said, "This ......"

A subordinate next to him whispered, "My lord, no. We dare to escape from the Xiongnu, their identity is unknown, we came to the Western Regions with the order of Emperor Wu of our dynasty, we must not trust others, even if they are only two children. ”

Zhang Qian also felt that it made sense, it was true that his ten years of imprisonment had made him too uncomfortable, and he missed his hometown all the time and the great rivers and mountains of the entire Central Plains.

Zhang Qian was about to refuse, when a subordinate suddenly shouted: "My lord, someone has fainted!" ”

Zhang Qian immediately walked over and looked at a subordinate who had been trapped for ten years on his mission to the Western Regions, with skin on his cheeks and chapped lips, revealing a sad look.

This is obviously a symptom of dehydration, but in the vast desert, there are only two camels, and you can't kill the camels!

If the camels were killed, I was afraid that all of them would not be able to get out of this desert for an unknown amount of time.

Yang Tongtong walked over and looked at them with a sad face, and asked curiously, "Why don't you give him water, he is about to die of thirst." ”

The man who led the camel replied sadly, "There is no water left, there is no water left in the procession, unless two camels are killed." ”

Yang Tongtong and Yang Xinxin understood that it was not that they were unwilling to give this person water, but that there was no water.

Yang Tongtong said: "I have a way, you come with me!" ”

Yang Tongtong pointed to an entourage with a knife, and the entourage unexpectedly pointed at himself and said I, a little incredulous.

Yang Tongtong said with certainty: "It's you, come with me, otherwise this person will die of thirst." ”

The entourage glanced at Zhang Qian, Zhang Qian nodded, he was also very curious about what this child named Yang Tongtong would do, could he really save his subordinates?

Yang Tongtong said: "Uncle, do you cut a piece of cactus with a knife?" ”

This person hesitated for a while, thinking that the adults had said that they would listen to him, so they would support him!

After cutting a large piece of cactus, he looked at Yang Tongtong with this cactus, and Yang Tongtong said: "Come with me, what I ask you to do, you can do it, you will definitely be able to save him." ”

"Chop up the cactus and put it in his mouth!"

The person with the knife immediately did as Yang Tongtong said, and the person who fell to the ground frantically absorbed the water of the cactus, and then his face began to slowly recover.

However, in this scorching Gobi, just replenishing water is a way to recover.

Yang Tongtong said again: "Hurry up and move him under that big cactus, don't let him be exposed to the sun all the time." While the sun kills bacteria, strong UV rays can also burn the skin. ”

Zhang Qian and others understood a sentence, that is, don't be exposed to the sun, as for what bacteria and ultraviolet rays say, what kind of magical thing is this?

After staying on the shadow side of the cactus for a long time, the fallen man slowly opened his eyes and began to retch, but there was nothing in his stomach to vomit.

The green juice of the cactus can indeed replenish water, but the taste is naturally very unpleasant.

The fallen man looked at Zhang Qian weakly, and said guiltily: "My lord, I'm sorry, my subordinates have dragged down the team." ”

Zhang Qian responded with a sigh of relief; "It's good to wake up, it's good!"

Zhang Qian thanked Yang Tongtong and asked Yang Tongtong why he knew that cacti could replenish the body's water.

Zhang Qian and the others have not done this in the past few days, but as a result, two people lost their lives because of this.

Yang Xinxin immediately raised his hand and said: "I know this, the cacti in the desert are actually divided into thorny cacti and thornless cacti, for thorny cacti, thorns can not only lock in the loss of water, but also play a role in protecting themselves, after all, in this form, there are too few animals that dare to eat cacti." And thornless cacti can't protect themselves with thorns, so most of them have evolved poisonous substances. It's called a toxic base. Therefore, most thornless cacti are inedible, and these poisonous bases can directly act on the human nervous system and cause people to hallucinate, and in the desert, the appearance of hallucinations is undoubtedly equivalent to a lack of water, which is equally deadly. ”

"My brother's choice for the uncle who fell was a thornless cactus, which was not poisonous. The cactus you ate before should be a thornless cactus, and it will be very dangerous after eating it. ”

Zhang Qian bowed to Yang Xinxin and Yang Tongtong, and said, "I've been taught!" ”

Zhang Qian immediately asked people to cut down this cactus as a water supply on the way.

As soon as Yang Xinxin heard that they were going to cut down this cactus, he immediately stopped: "You can't do this!" ”

Zhang Qian's subordinates all looked back at Yang Xinxin, and Zhang Qian also looked at Yang Xinxin and asked, "Little girl, why did you stop us?" ”

Yang Xinxin replied: "Plants are also alive like people. Besides, it saved one of you just now, so do you repay it? ”

Zhang Qian hesitated, but still said: "But if we don't use it as a water supply on our way, I'm afraid we won't be able to reach our destination!" ”

At this time, Yang Tong came up and said, "Uncle Zhang Qian, you can cut off some of the flesh of the cactus, so that the cactus will not die." The cactus has a self-healing function, and the appropriate "damage" to the plant actually helps it grow, which is called the rejuvenation of the plant. ”

After hearing this, Zhang Qian showed a look of great surprise, these two children know too much!

Zhang Qian asked, "Child, how do you know so much knowledge?" ”

Yang Tong replied: "There is a record in the book!" ”

Zhang Qian was puzzled: "In the book? ”

Yang Tongtong smiled: "That's right, in the book, "Encyclopedia"! ”
