In life, in fact, the most rare thing to meet is a nobleman, and the nobleman of Da Niu is undoubtedly Sun Simiao.

It can be said that it is the luck of the bull to meet the nobles, and it is also the character of the bull itself.

The kind of thick straightness on his body makes it easy for people who meet him to have a good impression of him, and this kind of inexplicable ability to make people like to be close is very similar to Xiao Han. (vomit...) This was added by Xiao Han himself, and it is not the author's business...... ）

It can be said that even Xiao Han here, when he saw this honest man for the first time in Chang'an, he liked this kind of person in his heart. Although at that time, he planned to use the huge body of the big bull to go to the battlefield to help him block the arrows......

The four joys of life, meet the old acquaintance in a foreign country!

Xiao Han and Da Niu met again in this foreign land, and they were all overjoyed! Even the identity gap is gone at this moment!

Da Niu told Xiao Han about the interesting things he encountered after he and Sun Simiao were together, and Xiao Han laughed at him from time to time with Da Niu's original 'Flying Immortals'. For a while, Zhang Bao beside him was a little bored, and he just wanted to squat in the corner of the wall and silently draw circles.

"Big Bull ......"

I don't know how long later, a shout came from the room where the big cow had just come out. When Da Niu and Xiao Han heard this voice, they all closed their mouths in unison.

"Sun Daochang woke up?"

Xiao Han shook his mind for a moment, and immediately walked quickly towards the room. Rush to the front and push open the door and look in.

However, it is now morning. The light on the outside is strong, and the light on the inside is weak. As soon as he pushed the door, he couldn't see where Sun Simiao was for a while, so he could only shout inside:

"Daochang Sun, where are you?"

"Xiao Hou?" Sun Simiao, who had just taken a nap, was a little familiar when he heard this voice, turned around and looked at the door, and was also a little surprised when he saw the people who came in.

He came to Seoul with the fat chef, so he naturally knew that Xiao Han was also here. However, when he entered the city, the Hancheng officials said that Xiao Han had another mission and was not in the city, and he didn't expect Xiao Han to come here so soon.

Zhang Bao, the big cow behind him, also entered the room one after another, Xiao Han's eyes gradually adapted to the dimness in the room at this time, and when he saw Sun Simiao, who was still dressed in a Taoist uniform, Xiao Han felt inexplicably relieved.

stepped forward and took a step, Xiao Han bowed his hand first: "Daochang Sun, great!" I didn't expect you to come! Ever since the last time I said goodbye, I've been looking forward to seeing you again! Fortunately, you came, and these people in Seoul were saved! ”

Sun Simiao saw Xiao Han coming over, and stood up in his seat. Maybe it was because I had been sitting for a long time, and my body was a little numb and shaking, but fortunately, the big bull rushed up in time to hold on, and then I stood firm.

Waving his hand to let Da Niu let go of himself, Sun Simiao also solemnly bowed his hand to Xiao Han: "Xiao Hou is really ashamed of Lao Dao when he says this, it is you who saved the person here, not Lao Dao me!" The old way of practicing medicine to see a doctor, even if it is day and night, how many people can be treated? It's Xiao Han, I don't know how many people you can save in the future! When it comes to saving people, the old way is not as good as you! ”

"This ......" Xiao Han's face was red, especially red! Hurriedly helped Sun Simiao well, and then said: "Sun Daochang is too tormented to kill the kid!" This is just a few suggestions from the kid, and it is also the concerted efforts of the officials and people in the city to control the epidemic! The boy dared to take credit there. ”

"No!" Sun Simiao shook his head and said seriously: "Before I came, everyone was panicking about the plague! But only the king of Qin said: Fortunately, you are in Seoul! Even if the epidemic cannot be cured for a while, it will never spread! Now I look at it, and it has come true! And the result was much better than King Qin's prediction. ”

"Oh? Haha, lucky, it's lucky! Xiao Han's face continued to be hot when he was praised by Sun Simiao, so he could only touch his nose and smirk.

But as he himself said, it was indeed lucky! If the plague here is not malaria but something else, like smallpox, plague or something! Xiao Han absolutely didn't say a word, he just ran away, compared with others, his own life is still very important......

Sun Simiao didn't know Xiao Han's dirty thoughts in his heart, if he knew, he would probably slap this shameless man to death!

Looking at Xiao Han kindly, Sun Simiao laughed twice, and then asked Xiao Han with his hand: "Xiao Hou, there is something unclear about the old way, please ask Xiao Hou to solve your doubts." ”

"Daoist Sun, excuse me."

"The plague has been regarded as ominous since ancient times, and no one has ever sought its cause, how did you know that the plague was caused by mosquitoes and flies?"

"This ......" Xiao Han hesitated for a moment, just wanted to be perfunctory, but after seeing Sun Simiao's thorough eyes, he suddenly changed his attention.

"Daoist Sun, this matter... Need to talk about it! ”

"Oh?"

Sun Simiao didn't react yet, but Zhang Bao on the side first understood what Xiao Han meant, and immediately bowed his hand to Xiao Han and Sun Daochang: "Hehe, Sun Dao is here for a long time." The journey is hard, you must be hungry, in this case, please Xiao Hou to entertain you on behalf of the official, I will go and prepare some food first! ”

After that, Zhang Bao turned his head and left, and before going out, he dragged the ignorant bull out of the room together.

The door of the room closed gently, and the room was quiet again, there were no outsiders in the room, and Xiao Hanxin relaxed a little.

Asked Sun Simiao to sit down, Xiao Han himself sat opposite him, scratched his head, and said slowly: "Sun Daochang, some things are too fantastic!" You won't believe it, let alone understand it, so I won't tell you the root cause! To put it simply, these things were not discovered by the kids, but deliberately researched by someone. In the world of those people, everything in the world has its own reason, and they are constantly pursuing the ultimate reason, and this disease is just one of the things they study! ”

"Oh?" Sun Simiao raised his eyebrows, but he was not as surprised as Xiao Han imagined, he just looked at Xiao Han calmly and asked, "Research is reasonable?" Can you tell Lao Dao, what is the reason for the plague in Seoul? ”

Xiao Han thought for a while, and said in plain words as much as possible: "Presumably, Daoist, you also know that this plague is actually malaria, and this disease has long been recorded in ancient books!" However, it is generally said to be caused by smoke miasma. But as far as the kid knows, this disease can be understood as caused by an extremely tiny bug entering the human bloodstream! Because this bug must enter a person's bloodstream to get sick, blood-sucking mosquitoes act as a bridge between the bug and the human! As long as mosquitoes are killed, no one will get this disease again. ”

After Xiao Han finished speaking, Sun Simiao didn't speak for a long time.

His words are easy to understand in the eyes of modern people, but in the eyes of the ancients, they are no less than strange tales! This is also the reason why he has only explained to Sun Simiao so far.

There was silence for a while, and just when Xiao Han couldn't help but speak, Sun Simiao suddenly asked Xiao Han: "Xiao Hou, what do you mean: this plague is caused by a bug that the eye can't see?" But if you can't see it, how do you know it? ”

Xiao Han smiled bitterly and said to Sun Simiao: "Actually, it's not that this insect can't be seen, it just needs to be used with tools!" When the kid gathers the right materials, he can make this tool, and you'll know when the time comes. Moreover, not only this malaria, but many diseases in this world are caused by these small things! ”
