Vaccine!

Li Kou studied medicine and knew too well the lethality of the plague.

The greatest plague in ancient times was smallpox.

He remembered reading in a book that the Song Dynasty already had pox technology.

But that kind of technology is still very poor compared to the pox technology used in the Qing Dynasty.

Nothing else, he'll be inoculated with cowpox.

It's not that he can't have anything else, it's that he can't have a basic laboratory in his current environment.

Li Kou took some medicine from the drugstore, which is almost unused in modern times.

Just a few remained at the village clinic.

Pagoda sugar, which is also a type of sugar pill that Li Kou ate when he was a child.

It's just that he judged that the cause of the child's illness was in the middle of eating.

"It is a medicine that is poisonous, but all drugs must have consequences." Li Kou looked at the pair of adults and said, "You see, when you cook in the future, the raw meat and cooked meat boards must be separated, and the vegetable pasta board and the meat board must be separated, so as to ensure that children can't eat food with worms, in addition, my medicine may have some side effects, but it will be fine in three or two days." ”

The two adults couldn't stop thanking them, but they begged a lot of Langzhong.

But the child always looks good and commits again.

"It's the matter of your family's chopping board, everyone must remember that even adults must separate raw and cooked food chopping boards, and they must be divided into two with knives, and if there are no conditions, they must be boiled in boiling water for half a day." Li Kou watched the child eat the pagoda candy, thought for a while, and gently pressed it on the child's back.

Really.

"You wait for me here in three days, this child also has some trouble in his spine, I have a little medicine, give it to the child first, and then I will teach you how to take it." As Li Kou spoke, he saw Zheng Tu and the others put away the full table of food.

Li Dalang is an extravagant character, and this meal is made on a board in a mess.

"You'd better also pay attention to your personal hygiene before having a baby." Li Kou said.

Sister-in-law Zhang glanced at her stomach and hurriedly asked her what to pay attention to.

Li Kou saw that her red face was very plump, so he smiled and said that she should lose weight.

"The old people often say that there are blessed people, this is true, pregnant with a child or immediately give birth to a child, there is some meat that is beneficial to adults and children, but meat is not the same as fat, if you are a fat meat, there may be other problems, at least less exercise children are poor, it is recommended to do more relaxed exercises." Li Kou came up with two better solutions.

One is radio gymnastics, and the other is yoga.

He doesn't look down on the virtues over there, but he still has some recognition of yoga.

At least in kinesiology, yoga has some sense.

Zhang's sister-in-law just didn't believe it, but Zheng Tu and Li Kou agreed very much.

Zheng Tu said: "The Sprinkle family doesn't understand this, but they know that Li Dalang is cold-hearted and kind-this is not what the Sprinkle family said, this is what the Marquis of Jingluo Mansion said." ”

Li Kou said: "Belief or unbelief is reasonable. ”

After a while, Zheng Tu's family cooked another meal, and Li Kou was relieved when he saw that the two children had no special reaction.

The physique of the ancients was really strong.

It's just that this toughness only lasts for a short time.

Not to mention anything else, compare the length of human life in ancient and modern times.

Zheng Tu invited his neighbors to eat, and Li Kou looked sideways at others and saw that they didn't have much excuse.

If Zheng Tu is really that town in Guanxi, then he is still a good person at this time.

At least he hasn't harmed anyone else.

Li Kou understood in his heart that people's attachment to their children and grandchildren is really a matter of Buddha and demons.

"If Zheng Tu has a child, he won't be embarrassed by the Jin family's father and daughter, right?" Li Kou thought so in his heart.

He didn't eat very comfortably at this meal.

There's meat, but there's too much sand in it.

That's what coarse salt is left over.

There is wine, but he doesn't drink a drop of wine.

"Sister-in-law bothered a lot, I just eat in my mouth, and I'm used to eating spicy food," Li Kou asked carefully, "It's just this salt, where did we get it here?" ”

Sister-in-law Zheng said: "Either it's from the Xihe Road, which is also bought from the Tubo tribes, or it's the salt from Yuncheng, Dalang can feel rough?" This is already good, but there are also people who use water to boil salt to get the best, but the price is too high, and we ordinary people can't afford it. ”

What's so good about this at a high price.

It is nothing more than melting, filtering, and drying, but it is only effective if there is a preliminary industrialization.

Li Kou said in his heart: "The salt in the salt transportation city of Tubo is coarse salt, if the initial industrial filtration can be realized, this is also a profiteering industry, if you can master the salt transportation channel, it is not difficult to rely on this one to become rich in the world." In addition, there is Taitong Mountain in the west of Weizhou that can burn paper cement, and the red bricks of red clay burning paper in the east are strong and durable, and the energy to be used can also be bought from Huating County, which is very convenient. However, the initial industrialization needs steel, that is, I know how to make steel, where does iron ore come from? ”

He thought so, and his subordinates were not slow.

Sister-in-law Zheng saw that he really didn't like wine and meat, so she only ate the big bowl of noodles that she felt was cold.

"Li Dalang is really a character!" Sister-in-law Zheng has three more points of agreement in her heart.

After eating, Li Kou was about to go back, and he knew that Miss Ma must be waiting.

Zheng Tu and his neighbors sent him out of the door, wanting to stop talking.

Li Kou knew what he was asking for when he looked at them.

He said: "I am in the city all day, if there is any need, just come to find it, adults and children can come, even the children come by themselves, I have no reason to ignore it, if I have no medicine at hand, I will prescribe a prescription, you go and grab the medicine." ”

These words finally put these people at ease.

Zheng Tu admired: "Da Lang is really the best young man we have ever seen." ”

Li Kou said: "I was born in the land, grew up in the land, and in the next hundred years, why should I pretend to be a character in the land?" ”
