"Sun Zhenren, I beg you, you better do your medical research, these sideways are not what you want to study, you will benefit all mankind if you do medical research thoroughly." Zhang Nan said with a look of lovelessness.

Sometimes, you want to scold someone because you don't know him, and when you get to know him, you may want to hit him.

After listening to Zhang Nan's words, Sun Simiao felt that what Zhang Nan said also made some sense, after all, the way of medicine is his own way, and if he doesn't understand these things, he won't understand them. So Sun Simiao nodded and said, "Then Xiaoyou wants to let Lao Dao see how this thing heals." ”

After Sun Simiao finished speaking, he pointed to the electronic sphygmomanometer placed next to Zhang Nan.

Zhang Nan picked up the blood pressure monitor and said: "This thing is not for curing, this is for measuring blood pressure." ”

"Oh? What is this blood pressure Xiaoyou has to explain it to Lao Dao, this is something in medicine, Lao Dao will definitely be able to understand. Sun Simiao said confidently.

“...... Okay, so I'll just tell you about it. Sun Zhenren: Do you know what the heart is for? Zhang Nan asked.

"The master of the heart's five internal organs, Xiaoyou doesn't know what the old Tao is talking about?" Sun Simiao tentatively gave his own answer.

"There's nothing wrong with this understanding, let's just put it bluntly, the heart is responsible for transporting blood to all parts of the body, and the reason why blood can flow in the body is the credit of the heart." Zhang Nan said.

"This old way can understand." Sun Simiao nodded, although he didn't know if what Zhang Nan said was right, but Sun Simiao could still understand what Zhang Nan said.

"Okay, then I'll ask Sun Zhenren again, what does this blood run through the whole body." Zhang Nan asked.

"This is naturally the pulse." Sun Simiao frowned and said, this "vein" is what we call blood vessels.

"Okay, then let me give you another example, if a container can hold a bowl of water, but I have to stuff a bucket of water into it, what does Sun Zhenren think will happen to this container?" Zhang Nan asked.

"This ...... Naturally, the water will overflow. Sun Simiao said.

"Yes, that's right, that's the truth, in the same way, if a blood vessel is stuffed with too much blood pressure and too much, then the blood vessel will crack." Zhang Nan said.

"This, is this so difficult that it is the real situation of dying when the meridians are broken?" Sun Simiao said with a shocked face.

"Everyone in the world knows that if the meridians are broken, they will die, but no one knows that the meridians are broken because of the high pressure, and so on, what the pressure is." Sun Simiao suddenly found another word that he couldn't understand.

"Sun Zhenren doesn't need to know what this pressure is now, Sun Zhenren just needs to see it as a real thing, too high blood pressure is harmful to the human body, and similarly, too low blood pressure is not good, because the blood pressure is too low, some organs need blood to maintain but don't get blood, then it will stop working." Zhang Nan said.

Now Zhang Nan has also seen through it, what to explain new terms is simply nonsense, when there is no accumulation of knowledge, how to explain these things is not clear, so it is better not to explain, just take it and use it.

"Well, Xiaoyou continued." Sun Simiao nodded.

And this thing, you can directly see whether the blood pressure is high or low, if the blood pressure is high, then you have to take blood pressure medicine to maintain the blood pressure at a stable level. If it is low, then find a way to raise blood pressure so that blood can be successfully transported to all parts of the body. Zhang Nan said.

"Little friend, can Lao Dao try this blood pressure measurement thing, Lao Dao wants to see what his blood pressure is." Sun Simiao said.

"No problem, Sun Zhenren, you roll up your sleeves." Zhang Nan said.

After Zhang Nan finished speaking, Sun Simiao obediently rolled up his sleeves, and then Zhang Nan began to measure Sun Simiao's blood pressure, and soon, Sun Simiao's blood pressure came out.

"High pressure 110, low pressure 70, very normal level, Sun Zhenren is very healthy." Zhang Nan looked at the display on the blood pressure monitor and said with some surprise, it stands to reason that at Sun Simiao's age, there will basically be high blood pressure, and Sun Simiao's blood pressure is so normal, which makes Zhang Nan feel a little abnormal.

"Xiaoyou, what does a vertical stick and a circle mean on this, how do you know that this is a hundred." Sun Simiao asked with some curiosity.

"Well, this is for the convenience of counting, and we're going through a number that's been invented." Zhang Nan's nonsense also came casually, anyway, these things have not appeared now, whoever occupies it first is whoever.

"Oh? Crossing a door actually even has its own words. Sun Simiao was deeply shocked, Cangjie made words is known to everyone, but this crossing a door can actually make words by himself, and he can also put the words on the secret treasure to show blood pressure, how can this make Sun Simiao not shocked.

"This little friend." Sun Simiao smiled and said to Zhang Nan that when Zhang Nan looked at Sun Simiao like this, he knew that Sun Simiao had something to ask for himself.

"Sun Zhenren doesn't need to say it, I already know what you think in your heart." Zhang Nan said.

"Oh? Xiaoyou knows what Lao Dao thinks? That's great, what's your opinion, little friend? Sun Simiao said in surprise.

"This, with all due respect, Sun Zhenren, you just took this blood pressure monitor away, and you won't use it, it's not that I pity this blood pressure monitor, I want Sun Zhenren to learn more, and wait until your medical skills are completed, and then use these things." Zhang Nan said.

"Ah, Xiaoyou misunderstood, Lao Dao didn't want Xiaoyou to pass through the treasures of one gate." Sun Simiao waved his hand again and again and said.

"Don't want something? So what do you want? Zhang Nan asked strangely.

"Lao Dao hopes that Xiaoyou can give Lao Dao a chance, so that Lao Dao also worships this crossing a door, today I saw what Xiaoyou took out, Lao Dao knew how short-sighted his knowledge was, and I hope that Xiaoyou will not dislike it, and introduce Lao Dao into a crossing door, even if he is a person who serves tea and water in the sect, Lao Dao will die without regrets." Sun Simiao said.

"Sun Zhenren, you mean, you want to apprentice?" Zhang Nan asked cautiously.

"Huh? Can Lao Dao still apprentice? It's best to be able to apprentice. Originally, Sun Simiao wanted to be a registered disciple in the crossing gate, and he was satisfied to be able to see the real knowledge in the crossing gate, but now Zhang Nan said that he could actually apprentice, how did this make Sun Simiao not surprised.

"This ...... It's not a secret, we pass through a door and now I'm alone, Sun Zhenren wants to worship as a teacher, is it so difficult to worship me as a teacher? Zhang Nan said with some embarrassment, after all, this crossing gate was fabricated by himself, and now even Sun Simiao was attracted, which was completely unexpected by Zhang Nan.
