Su You picked out the materials needed for a kind of toothpaste from the materials he added and confused at will. Under Bai Shan's curious gaze, he packed the ingredients into three clay pots of different colors, and then mashed and stirred them until they became paste.

Due to the different formulations of the three materials, the resulting paste is also different in color. The inside of the first jar was off-white, and it was the closest to the toothpaste he knew. The second jar is earthy yellow, and the third jar is indeed light green. He first recorded the ingredient ratio of the ingredients in each jar, and then covered it and set it aside. It has not yet reached the level of production, and there is no need to consider preservatives for the time being, and he has not yet found natural materials to make preservatives.

He picked up another very hard stick, cut it into the shape of a toothbrush with a carpenter's cutting tool, and smoothed it with an abrasive cloth. Drill several rows of fine holes at one end of the brush head. Use tweezers to dip the hair that has been cut and dried into rice paste, five or six small tufts, and stuff them into small holes. Once it's all stuffed, the toothbrush is ready. I made five toothbrushes in a row, waited until the rice cereal was sticky and dry, and then tied the elongated hairs on the back into strips with thin wires so that they would not be easily pulled out. There are grooves on the back of the brush head, and thin wires are embedded in the grooves, which are flush with the brush head.

Bai Shan had been watching curiously, and then asked, "Do you use this brush to clean your teeth?" It looks like a brush for brushing a bucket, but when you make it smaller, it becomes a toothbrush? ”

Su You was stunned, when he said this, it was indeed like a small brush. But he certainly wouldn't admit it, and said, "Anyway, it's much better than a toothbrush made of bones and twigs." Look at the pattern carved on the end of this handle, don't you think it's very beautiful? ”

Bai Shan looked at the pattern of a cat and a tiger on the handle of the brush. Su You pointed to the toothpaste jar, "This is the key, my special ointment, every time I brush my teeth, I apply this toothpaste to the brush head, and brush it up and down the teeth, inside and outside, and bubbles will be generated during the brushing process." This ointment removes tartar, stains and whitens the teeth from the teeth. I also added herbs to eliminate inflammation and freshen the mouth. You say that if we bring this product to the market, will people buy it back and use it, and brush their teeth in the morning and evening? ”

Bai Shan nodded, "If it really has this effect, people will naturally fall in love with brushing their teeth." This is a consumable product, and if everyone brushes it in the morning and evening, it will be used in large amounts. How many people are there in the world, aren't we going to send commercial buildings? However, can't others study the ingredients of this toothpaste? ”

Su You nodded, "You got to the point." Because it is a consumable, the cost cannot be too high, otherwise it will be used for a long time and the people cannot afford to consume it. In addition, counterfeiting is also a problem, toothbrushes are just a brush, anyone can make it, toothpaste can be copied by people to study, and it will soon be able to make finished products to compete with us. ”

Su You thought that toothpaste, a livelihood item with a large amount and high profits, will definitely attract other businesses to come in and get a piece of the pie. From the production to the user, the toothpaste has to be transported, distributed, and put on the shelves, and if it is sold to other places, the transportation time will be longer. Toothpaste must be able to stay moist for a long time, and it must have a long enough shelf life to set a threshold for competitors in the chemical ingredients of moisturizing, thickening, and preservative.

However, there are various moisturizing and antiseptic soil methods in the world, and the knowledge is in the folk. After coming into contact with the elixir, Su You was a little in awe of the alchemist, if the alchemist wanted to make toothpaste and soap, Su You didn't dare to say that they couldn't make it.

The toothpaste tube is another threshold to stop competitors, and the plastic tube was previously made with an aluminum tube so that the toothpaste can be squeezed out. When the refining of aluminum metal is in their own hands, and it can set up problems for counterfeiters, the cost of aluminum tubes may be relatively high, but aluminum can be recycled, and users can deduct some expenses when they buy new toothpaste and bring back the old toothpaste tubes.

Su You already has an idea, first of all, the secrecy must be in place, and some links must be taken apart as much as possible, and the less people know, the safer. Even if others can make it in a year or two, then the price will be reduced and the cost will be spent, and everyone will fight me. No matter what happens in the future, now only I can produce toothbrush, soap, soap, and even shower gel...... Well, Wanjian Daily Chemical has monopolized the entire industry, and it will enjoy a few years of windfall profits first.

While waiting for the brush head to dry, Su You talked to Bai Shan about a series of daily chemical products such as soap and soap, and Bai Shan's eyes lit up. Brother Su's mind is different, I really don't know how he came up with such a thing? He was already thinking that when he fought for the world in the future, with Su You here, he wouldn't have to worry about the silver.

Su You didn't know that Bai Shan was already playing his mind, and he was still instilling these chemical products into him.

Su You also thought that the assassin who assassinated Yao Legend could emit a burning fireball, and there were smoke bombs that could emit yellow smoke, these things had to be studied as soon as possible to save his life at a critical moment.

Su You talked about the situation of Yun Zeguo Ou again, and many of them had just heard from Sun Xiuxiu. He also talked about the complex relationship between Yunze and Xinhaoguo, the pattern of the Three Kingdoms, as well as foreigners and Westerners...... The world is big.

Su You: "In the future, when you sit in the country, I want to travel around the world, and then go to the Western countries to explore the secrets of the world!" ”

Bai Shan: "Okay, I want to go as you say!" ”

Su You: "You can't, you want to be the emperor, maybe you will unite the three kingdoms, it is possible." ”

Bai Shan: "Okay, then I will rule the world, be a real founding emperor, and open the peace of all generations." ”

Su You: "Bragging is not a good boy, only say it when you do it!" ”

Bai Shan: "If you help me, I can do it, then it's not bragging, I don't rule the world, you can't travel the world!" ”

......

Each of them holds a toothbrush, scoops out part of the toothpaste from the three cans, starts brushing their teeth, communicates the effect after brushing, and then rinses their mouths before changing to another toothpaste. The first off-white jar is mainly made of beef and horse bone meal as a friction agent, and some cinnamon oil and plant medicine are added. The second tank is mainly made of limestone and minerals, and the third is made of coral stone and shell powder as friction agents. Chinese herbal medicines will be put to reduce inflammation and freshen the mouth, and salt, mint, honey and other materials can be added to distinguish the taste.

After trying all three kinds of toothpaste, the first one had almost no foam, and there were still residues of bone meal particles when rinsing, and the bone powder was temporarily ground, and the grinding was not fine enough. The second one is not bad, it produces some foam, and it feels like the teeth are much cleaner after brushing. The third one is not bad, but Xinhao is not close to the sea, and the coral shell material is not cheap. It seems that toothpaste with limestone and minerals as the main material is a better choice, and the calcium carbonate contained in it is also the main material of friction agent.

After brushing his teeth three times in a quarter of an hour, Su You felt as if a layer had been ground out, and he was much more relaxed. The bristles of the brush head are still intact and have not fallen out. This is just an experiment, and Su You doesn't expect to succeed in one attempt. He records the results of the trial so that he can adjust the ratio next time.

Bai Shan found a bronze mirror to look at his teeth, and he felt that his teeth were indeed a lot whiter. In fact, monks can use their vitality to remove dirt and blemishes from their bodies, and they can keep their teeth clean and white without brushing. Su You made this product for ordinary people or people with low cultivation.

The two talked about daily exercises, and Su You said: "When Master Ji arrives, the mold workshop on this side of the main building will be handed over to him to be responsible, Master Ji is already very familiar with the mold processing process, so you can rest assured that it will be handed over to him." On your side, the weaving cloth and boots can put Sun Xiuyun in full charge. We have to put our time and energy into cultivation and focus on duels in the ring. I heard the second elder say that Zhuo Quanyu and Luo Yeming are both cultivating behind closed doors, and we can't take it lightly. ”

Bai Shan defeated Luo Yeming last time, but he knew that his cultivation was slightly inferior to Luo Yeming, so he naturally didn't think that he could win the other party, he practiced very hard, no matter how hard and tired he was, he would grit his teeth and persevere, the building owner and the second young master Sun Tianen saw it in their eyes and appreciated it very much.

Su You now only has a few new projects left such as toothbrushes, toothpaste, soap, and refining aluminum metal that he must do personally, and these cannot be handed over to others for the time being.

He then carefully explained these tasks to Bai Shan. The workshop he named the daily chemical workshop should be built as soon as possible, and a separate aluminum smelting workshop should be built, and the personnel must be matched, and he immediately looked for reassuring personnel in the workshop, Bai Shan patted his chest and said that it was on him. Both of them are unanimously optimistic about Mao Sui, this person has a flexible brain, and is diligent and studious, and intends to let him join. Ou Keren can also be used, not just as a bodyguard.

When it was time to practice again, the two looked at each other, their faces were bitter, and they could only go to the practice room hard. They knew that not everyone could get the guidance of the landlord and Lin Boqiu, and the two of them also cherished this opportunity, painful and happy.

......

Inner house. Sun Xiuyun asked her cousin what she had talked about with Su You? Sun Xiuxiu wanted to tell her, and she also had to tell the elders of the clan the information she had just obtained. Su You has become more and more important, and the clan needs to adjust its attitude towards cultivating and valuing him accordingly. Maybe she didn't pay attention to it herself, she was subconsciously happy to see Su You can continue to surprise the family!

She was about to speak, when someone pushed the door in, it was Sun Xiuxiu's mother. Sun Xiuxiu's mother's name is Ji Xue'e, and the Ji family is also a famous family in Xinhao, and many people in the clan are officials in the court.

Sun Xiuxiu greeted her mother, and Sun Xiuyun also saluted her aunt. Ji Xue'e saw that Sun Xiuyun was also there, and chatted with her with a smile. Sun Xiuyun saw that her aunt seemed to have something to say and planned to leave. Ji Xue'e said: "Yun'er also stays, you can listen too." ”

Ji Xue'e seemed to be pondering her words, and said for a while: "Xiu'er, let me ask you, do you have a good impression of Director Su You?" ”

"Ahh Sun Xiuxiu didn't expect her mother to ask her directly like this, and she was caught off guard, and she didn't know how to answer for a while. Sun Xiuyun next to her also said "ah", and was also taken aback by her aunt's question.

Seeing that Sun Xiuxiu did not deny it, Ji Xue'e sighed secretly, she was too familiar with her daughter. So the day before yesterday, when she heard her daughter say that she would divide half of her resources to Su You, she knew that it was not good.

She knew that her daughter was very talented in cultivation, and she was extremely persistent, and her cultivation was a thousand miles a day, and the clan had high expectations for her, and the patriarch even changed a lot of clan rules for her, using her as a boy to cultivate.

How can Xiu'er have a good impression of an instrumentalist? Even if the landlord promoted him to the top supervisor, he was still just a member of the family business building in her eyes. So when someone told her that she saw her daughter and Su You meet alone today, and they chatted for a long time, and she heard that her daughter met this Su You when she went to the Golden Building last time to celebrate the third uncle's birthday, Ji Xue'e couldn't sit still.

Ji Xue'e tried her best to relax her tone, "You are my daughter, of course I hope you are good as a mother." Our Sun clan is a famous family, and the Ji clan who is a mother is not bad. The women of our family will eventually choose a noble and excellent man as the marriage object, and on your terms, you can even marry into the palace and become the queen's concubine, bless the lintel, and protect the family. And you care about an ordinary person, a guy in a commercial building, and you have to give him your precious resources, and you have to meet him alone today. Do you know how much impact this will have on your reputation, so that outsiders will see you and the Sun family? ”

Sun Xiuxiu was sad in her heart, although she was not as worried by her mother, she did have a good impression of Su You, and her good impression was still increasing. He is also the only young man he knows so far who has a crush on him. When I was with him, I didn't reject him, and I even felt comfortable.

Although I didn't think about being with him, I also thought about the huge gap in the identities of the two. Now being questioned by her mother in person and clearly opposed, Sun Xiuxiu feels sorry for Su You and is confused about her future.

She once talked to Sun Xiuyun about whether there is really love at first sight and long-term love in the world, the two of them are just simple love together, regardless of status and status, and don't care if they are the right person.
