"Speaking of this animal, if you pay attention to the heat preservation of the young chicks, you may be able to carry out breeding ......"

Accidentally, Zhang Yifan himself digressed. But at this time, a maid came in at the door, bypassed the stable women in the middle of the courtyard, and reminded the princess: "It's past noon, it's time for lunch, and you can't delay it any longer!" ”

Hearing this, everyone felt that they were really hungry!

The crown princess was naturally hungry, and after looking around, she ordered: "I can listen to it so much that I forgot to eat." Okay, it's time to eat, let's eat here! ”

Hearing her words, the maid beckoned to the door, and a group of guards came in with food boxes.

This is the maid who served the crown princess has already sent someone to return to the city and pack the food. Of course, ordinary maids and guards must have no share.

Except for the guards and maids on duty, the others bought food from the village. All of a sudden, the village was lively.

Zhang Yifan's house doesn't have tables and chairs, but it doesn't matter, naturally there are guards moving from elsewhere. The crown princess also invited Zhang Yifan to dine with them.

In this regard, Zhang Yifan did not refuse. This is his house!

Besides, he agreed to eat, that is also to look up to others, otherwise he will drive people away, what's wrong!

So, there were four people at a table, including the crown princess, Zhu Di, Zhu Jingjing, and Zhang Yifan.

Zhu Jingjing watched this scene, and the smile on her face couldn't be hidden.

It was Zhu Di, looking at Zhang Yifan, and then at his eldest sister, and sighed in his heart: It's too obvious!

Zhang Yifan's calmness surprised the crown princess secretly. In the past, she really hadn't seen Zhang Yifan like this, even if she didn't identify herself, it was still very rare.

This really has to be a baby in the countryside?

To be honest, the princess's mind was not on eating, Zhu Biao was not around, and she didn't insist on eating, but asked Zhang Yifan curiously: "Now that these dishes are on the table, is that what you said are that those microorganisms will also be there, and we will eat like this, will there be no problem?" ”

"No!" When Zhang Yifan heard this, he couldn't help but smile and said, "There are too few microorganisms, in fact, it will not have an effect, they need time to multiply, and when that time comes, it will feel that the food has spoiled." In fact, under normal circumstances, our body is relatively resistant to ordinary microorganisms. Those who can't be immune, have been eliminated in the long river of history, that is, they can't survive at all, and they can't pass on their ancestors to have descendants! ”

Speaking of this, he paused and had to remind again: "When the human body has a wound, or when it is very weak, it is necessary to pay attention to the problem of microorganisms." In other cases, wash your hands before and after eating, pay attention to hygiene, eat cooked food, drink boiled water, and that's pretty much it! ”

Hearing this, Zhu Di suddenly interjected and asked, "That means that clear water can't be drunk directly?" ”

He led the troops to train, and most of the time, when he saw the sergeants heating up, they drank water directly, and did they cook it! Even himself, who sometimes does it.

"Of course!" Zhang Yifan listened, looked at him and said, "It's the same as the air, it looks clear, but in fact, there are microorganisms." It must be boiled before drinking to ensure health. Otherwise, if you drink too much, you will eventually get sick. ”

When Zhu Di heard this, his expression was serious, and he immediately asked again: "When will your tool that can see this microorganism be made?" I want to see it with my own eyes! ”

"I want to see it too!" When Zhu Jingjing heard it, she couldn't help but follow the request.

Zhang Yifan glanced at her diagonally opposite, and then replied: "It's not easy to do it, I'll contact you again when I make it later." ”

Hearing this, the crown princess glanced at Zhu Jingjing, then looked at Zhang Yifan and said: "I think you should be very talented, I can recommend you to serve the imperial court, you can rest assured, I will definitely make you an official, how about it?" ”

Not to mention what Zhang Yifan said about the microcosm, just in terms of medical Taoism, she felt that it was a pity not to use Zhang Yifan. Therefore, although Zhu Jingjing had been reminded, she still wanted to solicit it.

When Zhang Yifan heard this, he immediately shook his head and said: "I don't have the heart to be an official, I'm not free, I'm restricted, I can't do what I want to do, and I'm most annoyed by socializing!" ”

In the end, he silently added a sentence in his heart: I'm still afraid of death! I'm afraid of being an official of the Hongwu Dynasty!

The crown princess was a little surprised when she heard this, and looked at Zhang Yifan with wide eyes. Because she felt that Zhang Yifan's words just now were a bit old-fashioned, and he seemed to have experienced a lot, and it was definitely not from the mouth of a young man!

"Then how about letting the court reward you with a title, you don't need to entertain, you have a title." Zhu Jingjing listened and proposed again.

Saying that, she went to grind the princess again and said: "Sister-in-law, you said that with his merits, two ways to save people will still benefit future generations, and one title is not too much, right?" ”

"......" The crown princess was speechless when she heard this, and couldn't help glaring at her and said, "You said that the title is the title, do you think the title is radish and cabbage?" ”

Zhu Di didn't hear it, he just cared about eating, otherwise he was afraid that Zhu Jingjing would also come to grind him.

However, on the side of the crown princess, she changed her words and said: "You said this today, if it proves to be really useful, I will work hard to see if I can help you win a knighthood!" ”

Speaking of this, she also sighed: "If it is really useful, this is related to the inheritance of children and grandchildren, and there are countless living people, even the royal family will benefit, I believe that Jing Jing's title is not too much!" ”

Zhang Yifan listened, and he could confirm in his heart that this big family is definitely the founding father, either a prince or a marquis, and he can speak well on Zhu Yuanzhang's side, otherwise he would not have this promise!

If it is a title, it is only related to medical Taoism, and it will not affect Zhu Yuanzhang's throne, it should be fine, right?

When Zhang Yifan was thinking about it in her heart, the crown princess thought of her newborn daughter and her two-year-old son, and couldn't help but sigh there again: "People, it is indeed not easy to live. When I was born, I was worried about dystocia, and after I was born, I was afraid of dying young, and it was not easy to live to adulthood! Maybe it has something to do with what kind of microbes you said! In this regard, you really have to pay more attention, and it is better to believe that there is something than to believe that it is not! ”

Even if it is royal, there is still a matter of children dying young. In other words, in this ancient world, the death of children should not be too ordinary.

When Zhang Yifan heard her emotion, he also understood, nodded and agreed. But immediately, he suddenly remembered something, so his heart moved, and he immediately looked at the crown princess and said, "That, there is a matter, can I trouble you?" ”

Of course, he saw that this family was in an orderly manner, headed by this sister-in-law, so he made a request with this sister-in-law.

Hearing his words, even Zhu Di, who was eating with his head down, looked up at him, because he had been dealing with Zhang Yifan for three days, and he didn't take the initiative to hear Zhang Yifan make a request.

"You say!" When the crown princess heard this, she was also a little curious, and looked at him and responded.

He doesn't want to be an official, so what else does he want?

Is it asking for money? There will definitely be a reward for him.

As a result, I heard Zhang Yifan say to her: "Can you help me find the sick cow, that is, the kind where the cow has sores and smallpox!" ”

Smallpox was a terminal disease in ancient times, and most of them would die if they were infected, and only a very small number of lucky ones could survive, and there was no cure, which was a self-limiting disease.

Therefore, Zhang Yifan has long been thinking about this matter and wants to vaccinate himself against cowpox to prevent smallpox infection in the future; By the way, let everyone in the village be vaccinated, so as not to have people who know each other die because of this.

But the key point is that there are three cows in his village, none of which are infected with smallpox, and he has also inquired about the surrounding villages, but he has also found nothing.

Now this big family seems to be very powerful, so he doesn't mind talking about it, and it's no problem to benefit them when he solves the problem himself.

However, as soon as he said this, the people who heard it were shocked.
