The north wind is as sharp as a knife, and Jiangnan is another scene. Since passing Zhenjiang, I have never seen a icy in the cold winter. Time is too hurrying and it is the New Year's Day again. The students who Cai Chong originally agreed to have only had to enter the school after the New Year.

He went from Hangzhou to Kaifeng and returned to Hangzhou from Kaifeng. Although Cai Yan rushed forward, he still missed the New Year’s reunion dinner. By the time he entered Hangzhou City, it was already the second day of the Lunar New Year in the fourth year of Zhenghe.

After several months of going away, I couldn't hide my excitement when I saw Su Mei again. Before the seventeenth help, Cai Huang jumped down...

"My son is careful..."

"Mom~"

When rushing into Su Mei's arms, Cai Yan finally looked like a child. Su Mei smiled and gestured to her waist and abdomen, and said with a smile: "My son has grown a lot taller now!"

Cai Yan held her warm palms and said with some concern: "The child has caused trouble again in Kaifeng. Isn't my mother angry, right?"

"hehe……"

Su Mei chuckled, held his little hand and walked into the door, and said with a smile: "My son was furious about the beauty. My mother is envious of such a heroic thing!"

Cai Yan smiled bitterly and said, "Mother's words are even more cruel than hitting her child..."

"hehe……"

Su couldn't help but smile again.

"My mother is reluctant to beat my son, but... she needs to explain to her mother why she doesn't want to go to the palace to study? Isn't it good to be the companion of King Ding?"

Cai Yan scratched his head and was speechless. Could it be that what he did was so obvious? How could anyone guess his intentions? He couldn't help but have a bitter face.

"Did my mother think it's really good to be a lucky person when she goes to the palace to study?"

Su Mei was stunned and couldn't help but smile, "When did the prince companion become a lucky minister again? Don't my son know that only the second-class Jinshi are qualified to become a prince companion?"

Cai Yan smiled bitterly and said, "Ordinary people still attach importance to children's education, not to mention the prince and grandson, it is not surprising to choose a second-level Jinshi or a top student. It is not surprising that the second-level Jinshi is still young, and when he enters the palace to study... Isn't it just to accompany King Ding to eat, drink and have fun, and be a clown and laugh all day long?"

Su Mei was speechless, and knew in her heart that what he said was not bad. She grew up with her childhood and her feelings would naturally be deeper. However, the Song Dynasty was not the Ming Dynasty. If it were the Ming Dynasty, Cai Wang would rather enter the palace to be a child, because he knew that the emperors of the Ming Dynasty were all unique and had a strong personality and a person with a temperament.

What about the silence?

The Emperor of Song would go against all the literati in the world in order to get married? It would be impossible to think about it with his butt.

Cai Yan pulled Su Mei's arm, almost like she was tugging hard, trying her best not to give her time to think, and she was muttering...

"Mom, don't worry about the child. The child is in the same way as his mother, and he also wants to inherit his mother's career and become the number one businessman in the world~"

"You're just talking nonsense. Do you think it's so easy for merchants... Slow down, don't fall..."

Cai Yan didn't want her to worry about her, and Su Mei was afraid that he would fall to the ground, so she had to speed up her pace with the force. She looked at the mother and son, Anon, Guo Huan, Gu Qinniang and others and smiled bitterly again. Isn't this a real child in one day? Why did she cause so many troubles?

Cai Yan ignored how others thought and returned to a familiar place. He had not eaten, drank, urinated, and slept peacefully for many days. He completely let himself go, and his children also had a few days of repairing holidays.

Su Mei's mother was afraid that he would suffer in the capital, and she was afraid that she would not be able to eat and drink well. She prepared meals in different ways. Cai Yan did not leave her yard for five consecutive days. Outsiders didn't know what he was doing, and she was as gray as a mud monkey all day long.

"Bangbang."

"Da'er, is my mother in?"

"Come in."

"Squeak."

Su knocked on the door twice and pushed open the door. He saw that he was stirring the pan with a stick.

"Zhang'er, there is a dyed cloth craftsman at home."

Cai Yan was stunned, then understood what she meant, shook her head and said, "Mom may have misunderstood. The child did not want to dye cloth, but made some soap."

"Soap?"

"Um."

Cai Yan stirred the blue ash for most of the day and prepared to filter it and concentrate it. Seeing that she was a little confused, she scratched her head with her black hand and said, "The child also remembered when she was in Kaifeng. Mother knew that Sun Banxian, who set up a stall outside our house all day? He was sick in Kaifeng, so the child thought of doing some soap to wash his hands and disinfect it."

Su Mei couldn't help but smile and said, "It's not that there is no bath bean at home, so why do you need to do it..."

Su Mei was stunned, as if she realized something, frowned and waited for his explanation.

Cai Yan spread the gauze on the pottery basin and said, "I don't know how bath beans are made. I think it's troublesome than soap. Soap not only makes oily, but also makes it possible to sterilize, wash your hands frequently, and get sick less."

"The bath beans are fragrant, and the soap can be fragrant and it is also simple to make. You only need to use lard, lamb oil, fish oil... as long as it is oil, boiled with blue-gray water, you can make it. It's very simple."

"There are fish in the north, and their name is Kun... Goryeo, there are big fish in the north of Japan. Just like a fish as big as our house, a fish can make tens of thousands of pieces of palm-sized soap, and even more, a piece of soap..."

Cai Yan scratched his head and said, "Only two or three pieces of soap can produce a piece of soap, one piece is worth more than ten bath beans... it will be sold for twenty or thirty cents, right?"

"More than that." Su Mei suddenly spoke and said solemnly: "Soap really only requires oil and blue-gray water?"

Cai Yan scratched his head and said, "Why should you do it as a child?"

"Um."

Su Mei nodded and agreed, and made the first piece of soap in the house of the Song Dynasty.

The soap is very simple to make, but there is no caustic soda in this era, so it can only be replaced by wood ash water. I am afraid of failure. I can't master the amount for the first time, and I use more wood ash. I only boiled it after concentrating many times. As Cai Yan said, I did get the first piece of soap, and looked at the turbid and odorous soap...

"This is what is made of lard and mutton oil. If it is sesame oil and soybean oil, the one made of jade is clear and the appearance is much better. Add some floral fragrance like rouge and water powder. A piece of fragrant soap should be sold for fifty cents, right?"

Just by the wooden basin in the room, Su Mei tried the cleaning effect and found that it was more useful than bath beans. She smiled and said, "If you really use good oil to make it, two or three hundred bucks will not be expensive."

"There are really such a big fish in the north of Goryeo?" Su Mei asked suddenly.

Cai Yan thought for a while and said, "There is a fish in Beiming, whose name is Kun... Although "Xiaoyaoyou" is a bit exaggerated, it is not a nonsense. A fish as big as a house in the north is called a whale, an ancient giant beast."

"This kind of fish is different from the fish we eat. It is not that they stay in the water and cannot come out. They must show their heads and breathe every two or three minutes, otherwise they will be suffocated to death. You can see the water columns they spray from a distance. As long as you find it, they are often a group of people, and they can be caught with the Eight-Nuo Crossbow."

"Water column?"

Su Mei nodded slightly. As a member of the pirate, although she had never gone out to sea several times in her life, she heard the old people say when they were bored that there were indeed people on the sea that appeared out of thin air.

Cai Yan nodded and said, "The nose of a whale grows on the top of the head, and it will spray water when it is exposing. However, we are near the sea, and the water is shallow, so it is not easy to see them. Whether it is sauerkraut, or sesame oil, soybean oil is much more expensive. At the beginning, we used these oils to make soap. It is impossible to make soap. The method of making soap is relatively simple. At the beginning, my mother could lock the method, but no matter how confidential it is, it will still be known. There are always people who are willing to pay high prices to buy craftsmen."
