In front of the gathering of the people in the city, there were also more than a dozen basins filled with clean water, and in front of each basin was placed a bar of soap for the crowd to test. Next to it was a long table filled with piles of soap, not only square, but also round and lotus-shaped......

There were also a dozen or so beautiful palace maids standing in front of the long table, with good figures, who were responsible for collecting money and giving soap to customers.

The king of Shu not only knows how to teach, but also knows how to draw inferences.

"I can't see that the King of Shu still has a bit of talent for business!" Zhu Yuanzhang nodded secretly when he saw it, and said to Lu Chang and Gao Qi beside him, and there seemed to be no sign of anger in his tone.

In fact, he used to look down on businessmen, but since he talked to Qin Yu about the method of cutting leeks, his concept has completely changed. Merchants can earn a lot of silver for the treasury, and it doesn't seem so lowly.

If there was no Qin Yu, he would always have the concept of looking down on businessmen, and in history, Zhu Yuanzhang copied Shen Wansan's house and sent him to Yunnan. Of course, there is another reason why Zhu Yuanzhang raided his home, and that is jealousy. At that time, Shen Wansan not only helped him build the city wall, but also offered to help him reward the three armies, which made him feel the powerful power of Shangjia and the threat to the imperial power.

So later, Zhu Yuanzhang banned the sea.

Now that he has learned Qin Yu's method of 'cutting leeks', he is no longer afraid of businessmen. After earning 50 million taels of silver in vain, he even wanted to support the merchants. After all, the more money a merchant makes, the more leeks he will cut.

After the concept changes, Zhu Yuanzhang will no longer ban the sea.

"Not only did the emperor not reprimand the king of Shu, but he actually praised him?" When Lu Chang and Gao Qi heard this, they both felt incredible, remembering that the emperor seemed to be very disgusted with merchants in the past.

Several people squeezed out of the crowd and quietly came to Zhu Chun.

"Father!" Zhu Chun was about to make a big salute, but was pulled by Zhu Yuanzhang, "Don't disturb the people!" ”

"Yes!" Zhu Chun said.

"Chun'er, what are you selling?" Zhu Yuanzhang pointed to the things on the table and asked.

"Father, my son's son sells soap." Zhu Chun replied, "It is made on the basis of pig pancreatic soap and added spices. ”

"Pig pancreatic soap?" Zhu Yuanzhang, Lu Chang, and Gao Qi all said they hadn't heard of it.

"It is a soap formed by heating and stirring with lard and alkaline water, and a chemical reaction occurs." Zhu Chun said, "It was Mr. Qin who just taught us, saying that this is the saponification reaction in chemistry, father, Mr. Qin taught us the knowledge of chemistry, which is really useful!" ”

"Can soap made from lard remove stains?" Like the villagers of Lujia Village, the emperor and the two ministers were skeptical.

"Father, don't you know if you look at it?" Zhu Chun pointed to the crowd that was trying.

In front of the stalls, there was an endless stream of people trying to use soap. They put soap on their hands, washed them in a basin, and soon they were clean, and then they all let out a cry of admiration.

"I didn't expect it to work!" Zhu Yuanzhang said.

"Father and the two adults, would you like to try it yourself?" Zhu Chun instructed his subordinates to bring three pieces of soap and hand them to them, and brought a basin of water.

"I didn't expect to be able to wash my hands with something made of lard!" After Lu Chang and Gao Qi tried it, they were also amazed.

"It's true that this thing is much better than the soap we used to use, not only is it clean, but it doesn't feel like a prickle." Gao Qi also said, put it under his nose and smelled it, "And there is also a fragrance of flowers." ”

"Mr. Qin's chemistry is really amazing!" After Zhu Yuanzhang personally tested and felt that the effect was very good, he sighed in his heart, before Mr. Qin said that he used chemical energy to create a weapon similar to the plague, which can make pesticides without harming crops, at first I still didn't believe it, but now it seems that he did not deceive the world, this soap is the most direct proof.

"What do you two think?" Turning his head to Lu Chang and Gao Qi, the two ministers asked.

"The king of Shu made soap, which greatly facilitated the people." Gao Qidao.

"If this thing can be produced in large quantities, it will be a huge wealth income!" Lu Chang said, "It's just that the King of Shu, as a prince, sells on the street, which still damages the royal majesty." ”

"What do you mean to be detrimental to royal majesty?" Zhu Yuanzhang was immediately displeased, "Our emperor has created such a useful thing, which has facilitated the lives of the people, even if it is for the benefit of the people." Benefiting the people will not only not damage the royal majesty, but will be praised by the people. ”

Lu Chang listened and was speechless.

"Chun'er, how much does your soap sell for?" Zhu Yuanzhang asked.

"Father, the price of the sons is five taels of silver!" Zhu Chun said.

"Five taels of silver?" Zhu Yuanzhang's expression froze, "With such a high price, how can ordinary people afford it?" ”

"Father, the soap made by the sons and daughters was not sold to the people. Rather, it was to sell to the wealthy and nobles in the city. Zhu Chun said. At this time, the people who want to buy soap in front of the stall are already crowded and crowded, although the price is expensive, the crowd is still vying to buy it, for fear that the hand is slow and will not be able to grab it. After all, there are only a few hundred of Zhu Chun there, and they are gone when they are sold out.

"The price is so expensive, you can't be considered for the benefit of the people?" Zhu Yuanzhang frowned.

"Father, Mr. Qin only gave his sons and retainers two days off, and he couldn't make too much soap in two days." Zhu Chun said, "And the original intention of the sons was not to benefit the people from the beginning, but to increase some income for the palace." There are still hundreds of people to support in the Shu Palace, and the expenses are very large, and the money that the father gives to the princes every month is not much. ”

The officials of the Zhu Yuanzhang Dynasty had the least amount of money in all dynasties, and he still maintained the idea of being a farmer before, and felt that the money given to the officials was completely sufficient, so the monthly profits given to the princes were not much.

"After the retainers have this silver income, the Shu Wangfu will no longer have to cut down on food and clothing." Zhu Chun said, "As for benefiting the people, when the ministers have earned enough money, they will have time to produce in large quantities in the future, and it will not be too late to reduce the price." ”

"You're sincere." Zhu Yuanzhang said.

"I learned it all from Mr. Qin." Zhu Chun said, "Mr. Qin said, as long as you are upright and upright, you don't have to cower and be afraid of wolves and tigers, it's too tiring to live like that." ”

"The motto of our Lujiacun Primary School is: do what you want and don't exceed the rules."

"Mr. said that to be a man, we must follow the original ideas of our hearts, as long as we do not violate the most common rules in the world and the most basic morality, which reflects a person's open-mindedness, freedom, and chic ......."

It can be seen that since following Qin Yu, the whole person of the King of Shu has changed, and he has become unprecedentedly confident.

And the changes of several princes, Zhu Yuanzhang also saw it in his eyes and was pleased with it.
