Comrade Li Er was shocked, not because of how professional Zhang Nan was, but simply because he didn't understand.

There are some nouns in it that Li Er has never heard of, but Zhang Nan doesn't look like he is lying, so Li Er feels a little powerful.

Of course, Li Er naturally would not show timidity in front of Zhang Nan, and after coming back to his senses, Comrade Li Er opened his mouth and asked: "In this case, why don't the Tubo people feel anything?" ”

"There is so little oxygen on the plateau, according to what you say, why can this Tibetan people survive on it and still be able to move normally?" Li Er felt very strange.

After all, the Tubo people don't have more things than the Tang people, and there is no reason why the Tubo people can do it, but the Tang people can't.

"Are they any different from us?" Comrade Li Er continued to ask.

"If anything, it's actually different." Zhang Nan also replied truthfully.

Compared with people living at lower altitudes, Tibetans living on plateaus above 4,000 meters have dilated blood vessels and fast blood flow, which enhances the ability of blood to deliver oxygen to tissues, and although Tibetans' oxygen saturation is only 80 percent of that of people at low altitudes, they do not lack oxygen in tissues by increasing blood flow velocity.

In the same way, the same is true of the Tibetans.

After explaining to Comrade Li Er, Comrade Li Er said with an expression that was difficult to describe in words: "Why do you know so clearly? Could it be that you killed the Tibetans and cut them apart? ”

In addition, Comrade Li Er couldn't think of a better explanation, otherwise there was no reason for Zhang Nan to know so clearly, and even knew what changes had occurred in his body.

After listening to Comrade Li Er's questioning, Zhang Nan chose to remain silent, this is the only way for modern medicine, although China has always emphasized that the dead are the greatest, and the earth is safe, but the dissection of the corpse is a necessary way to help understand and improve medicine.

Looking at Zhang Nan's speechless appearance, Li Er didn't ask much.

"Is it really that useful to cut up corpses?" Li Er obviously didn't expect that the dissection of the corpse could be so useful.

"This is natural, Your Majesty, if a person is sick, he can't see what the disease is just by looking, if he wants to understand a disease more intuitively, he must see what the disease is all about." Zhang Nan said.

Li Er waved his hand, signaling that this topic could be stopped, after all, Comrade Li Er is not a doctor, so he has no great interest in this aspect, let alone such a thing as dissecting the corpse, Comrade Li Er does not want to delve into this issue.

"Tell me what we would do if we wanted to go to that plateau so that we couldn't tell us what you were talking about."

"Altitude sickness." Zhang Nan reminded in a timely manner.

"Yes, altitude sickness." Li Erdao.

"This is very simple, not everyone will have altitude sickness, the emperor, you only need to screen a group of people who have no reaction to the plateau, and this thing can be slowly adapted, if people who are unwell want to go, it is not impossible, you can first go to a lower altitude to live for a period of time, wait until there is no discomfort on the body, and then go to the plateau, live for a while, and slowly this disease will be cured." Zhang Nan said.

"It's as simple as that?" Li Er was a little unconvinced.

"That's right, it's that simple, and of course, the food has to change." Zhang Nan suddenly remembered that butter tea is also one of the conditions for overcoming altitude sickness.

"Oh? Why is that? ”

"Because this butter tea not only relieves fatigue, but also improves the body's ability to resist hypoxia." Zhang Nan explained.

Hearing Zhang Nan say something he didn't understand again, Comrade Li Er couldn't help but support his forehead.

"Okay, okay, I'll send someone to try it then. By the way, do you have any suitable candidates for this missionary matter? I thought about it, but I couldn't find a suitable person. ”

As for the question of candidates, Comrade Li Er has a headache, and those ministers in the DPRK and China are too old, let alone preaching, even if they are allowed to go to the plateau, Comrade Li Er estimates that it is enough to choke.

As for the young people, Comrade Li Er is not so relieved, after all, there is still some truth in the saying that there is no hair on the mouth and things are not handled firmly.

"Candidates? Your Majesty, just pick a few people from the military academy, some of them are learning this. Zhang Nan thought for a while and said.

"It's not appropriate, the cadets of this military academy can go with them, and they can even be used as the main force, but this leader must be trustworthy, and he must have such a relationship with the royal family." Li Er pinched his chin and said.

Li Er is not a fool, although he does not believe that this missionary thing to destroy the country can be done, but if it is really done, this religion is the only way to control Tibet, otherwise there will be a war. Of course, Li Er would not do such a loss-making business.

Controlling Tibet is not a small matter, Comrade Li Er naturally will not teach outsiders to do it, after all, the sky is high on the plateau, the emperor is far away, if it is given to outsiders, isn't it equivalent to splitting the earth and sealing the king?

"Then the emperor, what do you mean......" Before Zhang Nan's words were finished, he saw Comrade Li Er's gaze hanging on his body, Zhang Nan hurriedly took a few steps back, and then waved his hand and said: "No, no, absolutely not." ”

"I haven't spoken yet, so what can't you do? Where is it? Li Er saw Zhang Nan's appearance of retreating when he encountered an incident, and he was not angry.

"Your Majesty, don't want me to go to the plateau, it's not easy for the ministers for so many years, the grasslands and grasslands have also gone, and Silla and Silla have also gone, the emperor of this plateau, you still spare the ministers, and the ministers are still waiting for the beauty to give the ministers a child as soon as possible."

When it came to the issue of children, Comrade Li Er was also relieved, after all, seeing Li Lizhi early enough to have a child can be regarded as Comrade Li Er's thoughts as a father.

Even if the atmosphere of the Tang Dynasty is open, if a woman can't give birth to a child, this is also a big problem, and the saying that mothers are expensive by virtue of their children does not only happen in the palace, but also in ordinary families.

"It's okay if you don't go, but you have to find me a suitable person." Li Erdao.

In fact, Comrade Li Er really wanted Zhang Nan to do this matter at the beginning, after all, this matter was proposed by Zhang Nan, even if Zhang Nan made the plan in detail, it may not be the case if someone else implements it.

Therefore, Comrade Li Er still wants Zhang Nan to go, and Zhang Nan's identity is also very suitable, that is, he has a relationship with the royal family, he is young, and Li Er can be trusted, of course, this kind of thing like altitude sickness is not within the scope of Comrade Li Er's consideration.
