In late November 258 AD, after friendly and sincere negotiations between the two sides, Ma Guo represented the Fuxing Society and the Buhui Association, and Xiling Bujia, signed a package of agreements.

The two parties agreed that Fuxing Society and the Bu family formed an ally. Fuxing Society provided tung oil production and purification methods to Bu family's shops, and provided Bu family with two products: toothbrush and toothpaste. Bu family's obligation is: as long as the Bu family still controls Xiling, it is necessary to ensure the safety and unimpededness of the Mi family caravan.

Among the few existing fist products of Fuxing Society, the production of tung oil is the least difficult, and the mystery of it is discovered is sooner or later. So Guan Yi simply threw it out for favors. Moreover, taking advantage of this great victory in Hanfu, Meng Zihei on the southern border of Fuling County was severely damaged. Guan Yi extended his actual control line to Wuling County in Dongwu for at least 30 miles, which completely included Xiushan County, Chongqing, the largest tung tree planting base in China in the later generations. Therefore, even if the tung oil production technology is completely disclosed, Fuxing Society has an absolute advantage in producing raw materials.

Compared with tung oil, Bu Xie, who is also good at business, suddenly lit up when he saw a toothbrush - this is a bulk cargo that everyone needs. And it is a consumable - it has to be replaced with a new one in just a few months!

In this era, Guan Yi could only pierce one end of the wooden strip and insert a more delicate bristle. In general, this is just a matter of thinking. But how could a dignified time traveler do such a long-lasting business so that others can easily forge it? The toothbrushes he sells are all bleached.

In this era, it is quite troublesome and dangerous to make bleach. But there is no way. On the one hand, we have to take out new products to earn more profits in order to support more people. On the other hand, we must ensure that our business path remains unobstructed and we must have enough interests to firmly tie the Bu family.

In this era, to make bleaching agents, manganese oxide and hydrochloric acid are first required. Hydrochloric acid has been mentioned earlier and can be obtained through water-soluble brines. Manganese oxide is a natural ore. Some of them are also on the land of Fuling County.

After hydrochloric acid reacts with manganese oxide, chlorine is the most dangerous and troublesome part - this is a toxic gas. Therefore, Guan Yi’s choice is to not let chlorine be released separately, but directly connect it to the clean water on the other side by the sheep intestine tube - adding chlorine to water will produce hypochlorous acid. This is the effective ingredient of bleach.

This is a very complex and dangerous process. The production of pure bleach is much higher than the toothbrush itself. But it is worth it to do this: a white toothbrush and a black toothbrush are obviously a boar bristle toothbrush. What would you choose?

So even if the factory price of toothbrushes in Fuxing Society is 200 yuan per piece. The commercially-minded Bu Xie even ordered the sales price to a crazy 500 yuan per piece, but both parties are sure that this thing will definitely be a big sale. You insist on not using toothbrushes for a month. Only after cleaning your teeth with your fingers, you can understand what it would be like for the ancients to encounter toothbrushes.

The use of tooth powder started very early, and was widely used in ancient China. On the one hand, this thing is easy to imitate, which damages the reputation of time travelers. On the other hand, the taste of tooth powder is really bad, which affects sales. So what Guan Yi sold to Bu’s family was toothpaste.

Toothpaste in modern society is mainly divided into several parts.

The first is friction agent. Guan Yi directly uses light calcium carbonate - this is a by-product of preparing sodium hydroxide solution, so it is not useless.

The second is a wetting agent, which can effectively prevent the toothpaste from drying out and hardening. Guan Yi chose glycerol - all of which are ready-made.

The third is the adhesive, which is even simpler. Because its active ingredient is carboxymethylcellulose sodium salt. Although it sounds very high-end, this thing is actually widely present in all plants in nature. Although limited to the existing technology, Guan Yi can only do one process: alkalization, and the remaining etherification cannot be done because the production of chloroacetic acid is too troublesome, the adhesive produced in this way is far beyond this era.

The fourth is spices. Modern people know that its main ingredient is mint leaves. This thing is also everywhere in Fuling County.

The fifth is sweetener. This is just a little more than the amount of glycerin.

With a toothbrush and toothpaste matching, it can be foreseen that in the near future, willow branches and various tooth powders with unknown ingredients will be squeezed out of the market. It is precisely because of this that in the face of such huge benefits, the Bu family suffered all the unhappiness caused by the initial loss. The Bu brothers were very happy to sign an agreement with Ma Guo to form an alliance and friendly cooperation between the two parties.

In November of this year, the newly succeeded Emperor Wu, Sun Xiu, appointed General Sun Qian as prime minister and governor of Jingzhou, and at the same time, he appointed all of Sun Qian's four brothers as marquis. After successfully paralyzing Sun Qian, Sun Xiu contacted veteran Ding Feng through the left general Zhang Bu. During the La Festival on December 8, he captured and killed Sun Qian at the dynasty meeting. After that, Sun Qian's family was destroyed by the barbarians. Since Sun Liang, the imperial power that had been lost to the Eastern Wu for six years finally returned to the hands of the Sun Wu royal family.

After receiving the news from Jianye, the Bu brothers, who finally landed in their hearts, could not have the idea of ​​revenge on Fuxing Society and Mi Family Business. Because just past November, all the 10,000 toothbrushes and toothpastes transported by Fuxing Society were sold out in Jingzhou. In this month alone, the Bu family made a profit of 6 million yuan!

In the face of sufficient interests, no matter how big the hatred is, it can be eliminated with a smile.

The Bu family is happily counting money, and the Fuling County is also filled with laughter.

"Guan Zifeng, you said you were not doing anything too much? You didn't give it to my Mi Family Store to sell it, but you gave it to the Bu Family to sell it?"

"Hehehe, brother. I heard this after hearing this. Who made our great man only have Yizhou? "

Mi Zhao was not dissatisfied with Guan Yi's behavior of giving the monopoly of toothpaste and toothbrush to the Bu family. Not only was he not dissatisfied, but he expressed great appreciation to Guan Yi. Because everyone knew that the area of ​​Shu Han was too small, the population was too small, and domestic transportation was very inconvenient - the potential of this market was very limited. To sell the products to more people, he could only rely on the Yangtze River Waterway. The throat of the Yangtze River Waterway is now stuck in the hands of the governor of Xiling.

This was also quite helpless for Guan Yi: Shu Han was too weak, and he, a time traveler, had to think about it and then before he came up with a new product. After all, for weak countries, the general improvement in technology level means that the gap with strong countries will become increasingly wider.

For example, in the first year of Jingyao, Fuxing Society actually had a new product: calcium carbonate tablets that can be taken orally. This thing was originally a good product in such an era when the calcification intensity of human bones was far lower than that of modern people. It was a very low cost, but it could be sold at a very expensive price and could make huge profits. However, Guan Yi only dared to let the students of Fuxing Academy take it. Why? Because Shu Han had a small population and a small source of soldiers. If this thing was sold and the population and physique of the three countries were improved, then do you think this was a disaster or a blessing for Shu Han?

For example, the epoch-making super weapon of potatoes, Guan Yi only dares to plant them on a few hills. Moreover, because the production technology of this thing is too low, once the seeds flow out, others can copy them. So he had to spend a lot of effort to prevent the seeds flow out - he only dares to make the potatoes harvested into powder and go on the market in the name of bean flour. This is because, once the potatoes flow out, the Wei and Wu countries, which have more population and land, will receive much more benefits than the Shu Han, which has weaker power in the country! At this stage, the only result is that Shu Han will die faster!

For example, cement is full of limestone all over the mountains of Fuling County, so it is not too easy for time travelers to burn cement. But did Guan Yi dare to sell cement? The Shu Han army, which had always been weak in the number of people, was at a loss when facing the slightly larger Cao Wei rammed earth wall. If the Cao Wei walls were turned into cement, Jiang Wei would not let him go.

There are also revolutionary equipment for cavalry such as stirrups and horseshoes, so Guan Yi dared not mention it: the current Cao Wei cavalry put great pressure on the infantry of Shu Han. Once the stirrups are released, the combat effectiveness of the Cao Wei cavalry will increase by more than ten times - at that time, the only 10,000 cavalry in Shu Han will be of use to improve their combat effectiveness?

Therefore, in a weak country, time travelers are often not inventing and creating the better.
