"One stone rice is a thousand coins, and the kilogram of rice is ten coins. The price of bean grain is slightly lower, but no matter how much, kilogram of oil is thirty or forty cents, and one piece of soap is priced at thirty cents."

"Ten kilograms of rice, 100 kilograms of meat, 30 kilograms of soap can be used for two months. Such low-priced items can be easily used by ordinary people, and other merchants can't compete with my family. With the 20 million households in the Song Dynasty, one household, one yuan per month, and one yuan per 20 million households, you can get 360,000 jin a year. In fact, such low-priced items are not just sold for the Song Dynasty, the Liao Dynasty, Goryeo, and Japan. This item alone can be sold for more than 500,000 jin a year."

Su Mei looked solemn, knowing that the son who scratched his head was already calculating the minimum value. As he said, a pound of rice costs ten cents, and one piece of soap can be easily washed away oily soap. Sales of thirty cents are definitely a price that everyone can afford. Thirty cents a piece of soap, one piece of soap, two pieces of soap, the material fee alone is not enough, not to mention that there is also to pay labor, transportation, various taxes and government fees. Thirty cents a piece of soap, without thinking about it, Su Mei also knew that no one in the world could compete with them.

"Five hundred thousand coins a year..."

Su Mei looked solemn and nodded, "Don't ask about this matter, my mother asked someone to prepare a boat to catch fish."

Cai Yan frowned and said, "Mom, don't be anxious. There is still time left. Let's sell high-priced soap for a year or two before we start, and the ships heading north to catch fish will also be rebuilt."

"Rebuild?" Su Mei was puzzled and said, "We have to go to Liao Kingdom every year, so there should be no problem catching fish."

Cai Yan frowned and thought for a while, and shook his head and said, "I said before, whales... or Kun fish, they are large, often thousands or tens of thousands of pounds. Most of the places where they live are deep seas. Our ships... are not kids who disdain. Even the large ships built by the government are just offshore ships. Moreover, fish-catching ships need to be boiled on the ship on the same day or in a very short time. The ships built must be able to catch Kun fish, store them in sections or cook them directly on the ship."

"It is not very realistic to boil directly on the boat, because it requires enough carbon stone, and it also needs to avoid heavy storms and avoid causing fires due to boiling fish oil. Therefore, we need to choose a place in the north to build a village to boil fish oil nearby, and even boil soap nearby, which is not something that can be done in a short period of time."

Looking at his son who lowered his head and used a knife to cut the solidified soap, Su Mei had a weird look. She could have thought about so many things, how could a child doll think of it?

Cai Hua did not notice the strangeness of Su Mei's eyes. While cutting pieces of soap of different sizes, he said: "In a few days, the child may have to stay in the Longjiang Shipyard for some time. The cost of the deep-sea ship may be higher. If the mother hesitates, it will be considered as the money that the child borrowed from her mother. If she makes money, she will pay back her mother."

Cai Yan turned around and smiled brightly, automatically ignoring the weirdness in her eyes. She didn't ask about some things, and he didn't want to explain them. He said: "Deep-sea ships are more expensive and costly, but they are much more safe at sea. Overall, it's still worth it."

"From Hangzhou to Goryeo, Japan, there are not many products. Japan is also poor, but it does not mean that the two countries are really poor, especially Japan. Although it is a small wild country, it has the most gold, silver and copper in the world, and it is easy to earn ten times the value."

"The large ship carries valuable goods from the Song Dynasty to Japan and Goryeo. The return journey brings back soap, or sells them nearby to Goryeo, Japan and Liao, or returns to the Song Dynasty. They are not empty when they return. After a year, they make millions of dollars."

Cai Yan said a million guan and couldn't help but smile, saying, "The deep-sea ship must be built, and only the deep-sea ship can be safe enough. The road to gold and silver on the sea is one to go north to Japan and Goryeo, and the other to the south to the South China Sea."

"The Song Dynasty looked rich and powerful, and looked at Kaifeng's prosperity and enviable. My mother held the Cai family's fields, shops, and Hairui business. She was far more clear than the children about the reality of the people's pockets. Seeing the prosperity of various industries, how much money can the people really save?"

Speaking of this, Cai Yan threw down the prepared soap and sighed: "The business that can really make money is basically prohibited by the court. The prices are high. Some places cannot support their third child. They have to give birth to them and are drowned. Behind the prosperity is nothing more than life. Just like an old cow that cannot be beaten by a whip. He has to work hard to cultivate the land and put in a lifetime of hard work. What he gets is nothing but a handful of worthless weeds. When he gets old, he can't walk, he can't pull the plow, slaughter it with one knife, and take its skin and bones."

"The literati in the court are not idiots, and Lao Taishi Cai is even more intelligent. He knows very well what he is doing and knows how the impact his actions will have on the family."

"The three-sided law of the Imperial College is here. This year, all prefectures and counties must also practice the three-sided law. Not only do each prefectures and counties implement the three-sided law, but also increase the number of students... What does my mother think that Lao Taishi Cai is trying to do this?"

Su Mei frowned and said, "Practice the three-way abandonment method, one level after another, and the government will take charge of the world's learning. Old Cai Taishi thinks that he wants to achieve the world's teachers. If this matter is done, even if Old Cai encounters an unexpected accident, the court will be unable to put harm on the wrong side and make things difficult for our Cai family."

Cai Ying nodded, shook her head again, and said, "Once all prefectures and counties in the world implement the three-story school, each private school will gradually disappear. Each private school and college have been deeply influenced by each private school. After the academic year has been completed, they must consider their own interests both public and private. After the court has three-story school, all schools will be taught by the government, and all students in the world will become the government. As the host, Lao Cai will become the teacher of the world. If he has been abandoned for twenty or thirty years, the court will really lose his way to our Cai family."

"But this is just one side."

"The method of giving up three things is fundamentally based on the principle. The prefectures, counties and schools belong to the court, and the students of the world are also from the court. The scholars of the world naturally need to serve the court, not to serve the Cai family. From this point of view... the official family will not allow the old Taishi Cai to become the teacher of the world."

Su Mei was suddenly shocked, and then she realized that she was still thinking a little simpler. As Cai Yan said, even if someone came to be a teacher in the world, she could only be the current official family or the Song Dynasty court.

Cai Hua was silent for a while and said: "The famous celebrity Fan Zhi, Wang Pu from Bingzhou, Wei Renpu from Weizhou, Zhao Pu from Youzhou, Xue Juzheng from Kaifeng, Taikang Shen Yilun from Kaifeng, Lu Duan from Huaizhou, Song Qi from Youzhou, Li Fang from Shenzhou, Lu Mengzheng from Shenzhou, Zhang Qixian from Luoyang, Zhang Qixian from Caozhou, Lu Duan from Youzhou, Li Han from Youzhou, Xiangminzhong from Kaifeng, Bi Shi'an from Daizhou, Kou Zhun from Huazhou, Wang Dan from Daming Prefecture, Xinyu people Wang Qinruo, Ding Wei from Suzhou Prefecture, Puzhou Li Di, Feng Zheng from Heyang, Wang Zeng from Cangzhou, Zhang Zhibai from Xiangzhou, Zhang Shixun from Xiangzhou, Lu Yijian from Heyang, Wang Sui from Langzhou, Chen Yaozuo from Quanzhou, Zhang Dexiang from Linchuan, Yan Shu from Yuezhou, Du Yan from Zhending from Zhengding, and Chen Zhizhong from Hongzhou,

Cai Yan moved away from the paper and looked at Su Mei, who was frowning slightly.

"Did you see something different?"
