Lin Huan listened to Ma Qiang's words, first overjoyed, and then couldn't help frowning and asking worriedly, "Since it is the secret of the Malang sect, we can learn it?" ”

Ma Qiang said with a smile, "Our scientific school, like Confucianism, also pays attention to education, there is no way to see the door, and toothpaste and toothbrush can prevent dental disease in people, I wish everyone would have this thing in their hands in the future." ”

"Ma Lang has the world in his heart and has great benevolence and righteousness! Listen, you guys, whoever Ma Lang says to teach, you will teach whoever you teach, you are not allowed to leak what you have learned, and you are not allowed to steal the teacher if you don't learn, otherwise Ma Lang will not come forward, and a few of our old guys will also come forward to kill you! Lin Huan shouted loudly, and the young people around him didn't dare to frolic when they heard it, and shouted in unison.

The labor system or economic system of Dasong Village is actually semi-manor, because there is not much land in Dasong Village, most of the food is obtained through fishing, hunting, gathering, etc., which makes it impossible for a person or a family to obtain enough food, and only through collective cooperation can the whole village try not to go hungry.

Such a manor economy was actually the main economic model before the Tang and Song dynasties in China, and the later small-scale peasant economy had to wait until the beginning of the Tang Dynasty, when the fields were no longer divided by family, but by head, which also made the thousand-year-old family disappear since the Qin and Han dynasties, but also brought the disadvantages of the small-scale peasant economy to the external environment.

All in all, there are pros and cons.

But for Ma Qiang at this time, the manor economy is really convenient, at least in terms of division of labor and cooperation, everyone has a position that everyone is used to.

Among the five people in Lin Huan, Lu An is in charge of hunting, and he is ready to go out with a few hunting experts at this time, Yang Wanli is in charge of warehousing, and he is in the warehouse with his child Yang Chi all the year round, Yue Liang is responsible for iron and tool making, Guo Ping is responsible for farming and medical treatment, and Lin Huan is responsible for the affairs and defense of the village.

The rest of the village would follow the five according to their different skills.

"It's not difficult to make toothbrushes and toothpaste, so I only need four people first, Qingcheng, these people you are most familiar with, you help me choose one, I want one who knows how to carpentry, one who knows how to distinguish between ore and forging, one who is powerful and doesn't talk much, and one who is careful."

Ma Qiang is the big boss in the laboratory, so the second boss naturally did such a thing as picking people.

Lu Qingcheng looked at everyone and said, "If our village wants to say the most careful words, then Lu Yun, distinguish the ore and forge, only Uncle Yue can strike iron in our village, Yue Yang, why don't you come?" ”

Yue Yang touched his stomach and said a little unhappily, "I can't eat toothpaste, what are you doing here, it's better to find something to eat to fill your stomach." ”

"Yue Yang! If you talk nonsense again, your father is not here, I will beat you or not? Lin Huan shouted, "Qingcheng, don't want him, change it!" ”

Qingcheng snorted at Yue Yang, a little embarrassed, there are indeed not many people in this village who know ore.

"Sister Qingcheng, I want to go!" A small hand was raised on the side, "Uncle Father-in-law taught me to recognize stones, I know it." ”

It was Lin Zhi who spoke, Ma Qiang suddenly found that Lin Zhi didn't know when there was an extra white smoke in his arms, and when he was doing the five poultry drama just now, there was obviously nothing, so where did the loess go.

"Meow!" Ma Qiang felt that his legs were itchy, and looked down, oh, the loess was under his feet.

"Why are you here?"

"Meow~" - "Brush your teeth~"

Well, these two have developed a good habit of brushing their teeth.

I can't help but feel a little guilty when I think about how often I used to lie in bed and brush my phone until I fell asleep before I brushed my teeth. (It's obviously the author himself, what's the matter with me Ma Qiang?) ）

"Nyingchi.. You are too young, otherwise let Liu Hui come, Brother Liu Hui, you often help your uncle strike iron, right? ”

"Yes, I know some ores, too." Liu Hui is a strong man, with a beard and a little pockmarks on his face.

In ancient times, blacksmiths would always have some pockmarked pits, which were actually caused by the sparks splattered into the body by cracking the iron under incomplete protection.

"That's good, plus me and Guo Jin, exactly four people."

The second boss, Lu Qingcheng, reported to the big boss Ma Qiang.

"That.... Do you have a lot of strength or do you know carpentry? Ma Qiang wanted to ask a little deadly, but he still held back.

"Alright, then let's gather here in half an hour, let's go back and talk, and then Qingcheng, we need to use the stone grinding and carpentry tools later, can you help find it?" You also need to borrow the forging furnace from Uncle Yue, you go and talk to Uncle Yue. ”

"There is only one stone mill in our village, it is placed in the house in the middle of the village, I know where the carpentry tools are, I will go to find it, Uncle Yue, don't worry, I will say."

Laboratory props still need to be available, and such preparations are naturally done by the second boss.

So what does the big boss do?

Of course, the big boss is thinking about the problem! Do you still wash the test tube? That's what scientific dogs do.

Back then, Ma Qiang was also a person who worked as a scientific research dog, progressed from a scientific research dog to a scientific research worker, and then to the second boss and the big boss.

Of course, due to Ma Qiang's talent and opportunity, his progress is particularly fast.

Teach Lin Zhi to brush Bai Yan's teeth, Ma Qiang brushed his teeth for Loess himself, and then brushed his teeth again.

Breakfast is millet porridge with a black sauce.

Millet is the millet in the five grains, in fact, the five grains have always had different sayings, all in this era of the master Zheng Xuan believes that it is hemp, millet, millet, wheat, beans, and Zhao Qi believes that it is rice, millet, millet, wheat, and soybean, but no matter which one, millet is among them, which shows the status of millet at this time.

Millet is characterized by drought tolerance, and is a good choice for planting in areas where water is scarce or water conservancy projects are not sound.

But even so, the taste of the millet porridge that Ma Qiang drinks now is much worse than that of later generations, after all, the millet of later generations is the result of continuous optimization after two thousand years.

But after eating the barbecue for so long, Ma Qiang still felt that this bowl of millet porridge was extremely sweet.

After drinking the porridge, thanking the Lin family for their hospitality, and coming to the courtyard, Lu Qingcheng and Guo Jin had already prepared the materials.

"Brother Pony, what do you think?"

Ma Qiang walked down and looked at everything, and said with a smile, "Okay, then let's prepare for the grouping."

What we have to do is a toothbrush and toothpaste, the toothbrush needs wood, fine hemp rope, pig bristles or other animal hair, the standard can be judged by holding my toothbrush, this is very simple, Qingcheng you and Lu Yun are in charge.

And then there's the toothpaste, which requires a lot of materials, so I'll start by saying, what you say can be found directly, and what needs some time.

We need to use fat, limestone, plant ash, salt, algae or konjac, mint, pine leaves... Forget it, the pine leaves are not needed for now. ”

Ma Qiang originally wanted to directly make a toothpaste similar to that of later generations, but when he thought of the current test equipment, it is almost impossible to do complex chemical experiments without various glass instruments.
