All night long, Zhao Xing and Mi Zhen did not move anywhere except for talking, but even so, after getting up the next day, they were a little tired and looked very tired.

Zhao Xing came to the yard lazily, took a bowl of water and some salt handed over by his maid Cui'er, frowned and began to clean his mouth. When the bitter salt was evenly applied between his teeth, Zhao Xing couldn't help frowning, thinking that he had been traveling back for more than ten years, and it was still difficult to adapt to the habit of using salt powder to rinse his mouth as brushing his teeth. Should he find a way to make toothbrush and toothpaste, which not only facilitates himself and his family, but also keeps clean and healthy.

In the past, Zhao Xing was busy practicing martial arts and fighting with others. Some of the seemingly simple ideas were too late to take action. Now the major thing is settled. When he rinsed his mouth, he suddenly became interested in inventing the wound. For a moment, he was stunned by the sluice under the washing sluice. He looked at the frozen sluice under the sink, and was enlightened for a long time.

Mi Zhen, who came out of the room, looked at Zhao Xing stunned at the sink early in the morning, and then walked over and asked softly: "Honey, did you think of something important? Should you call Dian Wei to come and arrange it?"

Zhao Xing was interrupted by Mi Zhen and turned around and told her some of his ideas: "Does your wife feel it is very troublesome to rinse your mouth, wash your hair, clean your hair, and take a shower on weekdays?"

After being asked for such an inexplicable reason by Zhao Xing, Mi Zhen replied: "Since I was a child, I rinse my mouth with salt powder, smoked sandalwood, cleanse my hair, and bathed in clean water. I don't think there is any trouble."

Zhao Xing slapped his forehead and said to himself: "That's right, people who have never used toothbrushes, toothpaste, laundry soap, shampoo, and shower gel naturally think that the method used now is the best, hehe, then I will start with the revolution of life and open my eyes to the people of the Han Dynasty."

After Zhao Xing finished speaking, he excitedly left the courtyard where Mi Zhen lived and headed straight to his room. He didn't know what he was crazy about. Mi Zhen, who was left with unknown details, was still thinking about what Zhao Xing said: "Toothbrush, toothpaste..." is all about things.

After Zhao Xing entered the room, he took out a charcoal pen and a stack of white paper, and began to write on the paper some nouns that only he could understand, such as soap, soap, shampoo, coal stove, washboard, bra, can, pillow, reading glasses, magnifying glasses, thermos, tiles, milk candy...

After Zhao Xing thought he could make or imitate various items in this time and space with current technology, he found that there were as many as hundreds of items of large and small on a full page. If he had only his own strength, it would have been difficult to achieve it without three or five years.

So Zhao Xing called Dian Wei and asked him to come and call Ma Jun, Hua Tuo, Zao Zhi, Qin Yilu, Liu Jili, and several famous blacksmiths, carpenters, stonemasons, tailors and other craftsmen in Wohu City to come over, preparing to hold a "Invention and Creation Coordination Meeting" with everyone.

At noon, dozens of people from all walks of life in Wohu City who received summons, dropped their busy work, and rushed to the Taifu Mansion excitedly, except for Ma Jun, Hua Tuo and others who often go to Zhaoxing's mansion, the other craftsmen in the city were full of excitement and curiosity. Although everyone didn't know what the Taifu was calling for him to come over, everyone thought it was definitely a good thing.

It’s no wonder that everyone has these philanthropic ideas. Although everyone can settle in Wohu City, it means that they have been awarded more or less meritorious. Some craftsmen who even followed Zhao Xing in Wohu Village in the early days, but now it is really rare to meet the Taifu who lives in the same city like Zhao Xing today. It has not happened for many years. The last time Zhao Xing convened everyone to form a wooden tool research and development team.

After everyone gathered, Zhao Xing came to the conference from the room with a thick stack of sketches. According to the industries that various small inventions may involve, he began to divide the labor and provide on-site guidance and explanations.

Since he had aroused the urge to turn his teeth when brushing his teeth, Zhao Xing was naturally the first to ask everyone to design toothbrushes and make toothpaste.

He took a picture and began to gesture to several great carpenters: "The thing we made this time is called a toothbrush. It is about six inches long. One end is a hand-catched handle, and the other end is a brush head with fine hair inlaid..."

After several carpenters fully understood Zhao Xing's intention, he said to Hua Tuo: "Now the salt we use to clean the mouth is too simple, which is not conducive to removing the bacteria accumulated in the mouth at night. I want to ask the miraculous doctor to prepare a few ointment-like tooth powder. The specific formula has several possibilities: mix honeysuckle juice, salt powder, and talc powder to make a white paste object; mix salt powder and starch with mint powder to make a green paste; use green tea powder, white sugar, salt powder, soap bean powder…"

Hua Tuo often discusses surgical treatment with Zhao Xing. He naturally understands the bacteria mentioned in Zhao Xing and knows what Zhao Xing is doing to make these various combinations of paste paste, but he just asked with some confusion: "It is not difficult to mix these paste, but it requires a lot of salt powder and other Chinese herbal medicines. Even if it can be successfully matched, it must be a lot of cost, especially salt powder and sugar, which are very rare things for ordinary people. Did Guochang think of the future way out of toothpaste when he did this?"

Zhao Xing then called Qin Yilu and told him: "You only need to provide various herbs, salt, sugar and other items according to the needs of the miracle doctor to ensure that the miracle doctor can make toothpaste in a short period of time." Qin Yilu didn't ask Zhao Xing's reason, and nodded and agreed.

After completing the task of toothbrush and toothpaste, Zhao Xing called a few blacksmiths, and then took a sketch of a coal stove that could burn honeycomb coal. He began to gesture to several blacksmiths. This thing was not complicated and did not involve any chemical reactions. So Zhao Xing took a short time to explain it to several blacksmiths.

After talking about the idea of ​​making coal stoves, Zhao Xing talked with several blacksmiths about how to make iron canned boxes. Considering that vacuum compression packaging cannot be achieved in this era, Zhao Xing decided to use heating wax seal to isolate the air. Therefore, the task he taught the blacksmiths was to develop a light and thin iron sheet to facilitate the production of canned boxes. It was also very clear that it was not long before long.

When several tailors surrounded Zhao Xing, he took out a bra pattern with a little hesitant, and then muttered to everyone in a low voice. Soon, several large tailors looked at Zhao Xing with strange eyes, but the expression revealed in their eyes clearly understood the purpose of the things Zhao Xing needed to make them. When Zhao Xing took out a legend of briefs and a design that facilitated women's Yuexin to change to tight clothes when they came, the faces of several masters were already shocked...

Zhao Xing was too lazy to explain to these big tailors. After directly assigning the task, he called out several glass stonemasons who specialized in producing monocular telescopes for the military, and assigned the task of designing binocular telescopes. Then he specially proposed the idea of ​​using East China Sea crystal to polish a magnifying glass and reading glasses. These stonemasons are all skilled old craftsmen. After hearing Zhao Xing's explanation, they thought about the sketch for a moment and understood Zhao Xing's intention.

According to Zhao Xing's idea, if the stonemasons can make binoculars and then polish high-quality convex lens sheets and concave lens sheets, then he can try to create an optical microscope for Doctor Hua. Although the magnification is not necessarily high, it should be possible to study onion slices or something. Zhao Xing vaguely remembers that the microscope that his junior high school nature teacher brought to the podium in his last life did not seem to be dragging the tail that needed to be energized.

Zhao Xing thought that if Hua Tuo put on the reading glasses he designed and finally discovered something in the microscope through an optical microscope, his old face would have been very wonderful.
