"San brother! Third brother~" After Zhao Yangang talked to Yu Dai Zhou, he heard Zhao Xu calling him excitedly in the distance, and then walked over quickly and said, "San brother, I was wrong for my brother just now. These people are indeed disaster victims. You should write down the method of preventing and treating the epidemic. I will take it back to show it to my father!"

Zhao Xu now wants to fly back with Zhao Yan's method of preventing and treating epidemics. In the past two days, his father Zhao Shu and Han Qi and other husbands were frowning. Even Zhao Shu's body, which had just recovered, began to recur. If Zhao Yan's method of prevention and treatment can be brought back now, it will really solve the urgent needs of the court!

Seeing Zhao Xu's anxious look, Zhao Yan smiled and pointed to the doctor Zhou next to him and said, "Brother, don't worry, the one next to you is doctor Zhou from my house. He participated in the prevention and treatment of the victims' epidemic throughout the process. He knew better than anyone else. Now you take him away and let him write down the prevention and treatment plan on the way. Then you will give it to your father. And with doctor Zhou helping you in the future, you will definitely not make any mistakes!"

"Mr. Zhou Taihe is greeting His Highness Ying!" The imperial doctor Zhou also looked very frightened and immediately stood up to salute Zhao Xu. It was not until this time that Zhao Yan realized that the smooth imperial doctor Zhou was named Zhou Taihe.

"Haha, there is no need to be too polite. If I can help Yu Dai, I will be more confident in stopping the spread of the disease!" Zhao Xu did not expect that Zhao Yan would be so thoughtful. It is indeed much better than a piece of paper to have an imperial doctor with prevention and treatment experience to follow him.

Zhao Xu is quite impatient. Now he has a way to prevent and treat epidemics. He is worried about the victims in the city and Zhao Shu's health. So he said goodbye to Zhao Yan, but he was caught by Zhao Yan and said, "Brother, don't rush to leave first. I happened to open a small workshop here and produced something called soap. I will give it to you for a try first, and bring some for my father and others!"

Although the soap workshop cannot start normally due to insufficient raw materials, some oil and alkaline noodles were also stored in Zhao Yan's villa. Previously, taking advantage of the opportunity to train workshop craftsmen, the soap workshop also produced a batch of soap. Some of them were specially added to it in order to increase the effect of sterilization and insect repellency, Zhao Yan specially added some sulfur to it, which is suitable for use in this situation.

"It's time now? How can I still have the mood to try something soap? Daddy has been ill for the epidemic these days and has been coughing these days. I brought this good news back early, so I can also let Daddy recover from illness sooner!" Zhao Xu was good in other aspects, but his personality was a little impatient, and even later became emperor, he couldn't get rid of this problem. The reason why the later Xining reform was opposed by so many people was also related to Zhao Xu's impatient personality.

"This soap is a good thing. If the victims can use it, there is no need to worry about the spread of the epidemic. Unfortunately, the number of this thing is too small, so it is impossible for every victim to use it. I can only use it first for my father and a few people. In addition, you run around every day and sometimes you will come into contact with the victims. If you are not careful, you may be infected with the epidemic. So you must bring this soap with you and use it frequently!" Zhao Yan said very seriously.

As soon as he heard that this thing called soap could prevent the spread of the epidemic, Zhao Xu immediately took it seriously and immediately pulled Zhao Yan back to the villa. When Zhao Yan asked Lao Fu to deliver the soap to the living room, Zhao Yan briefly introduced it, Zhao Xu was a little dazed when he looked at the soap, because he really didn't expect that the so-called soap was actually a substitute for bath beans.

"San Ge'er, even if these soaps are better than bath beans, they are just something that cleanses the body. How can they prevent the spread of the disease?" Zhao Xu asked in confusion as he looked at the soaps in front of him. He saw that these soaps were mainly divided into two types. One of them was yellow in color, ordinary rectangular, and had a pungent taste, and the number was relatively small. The other was pink, and it was carved into a lotus shape, emitting a faint fragrance, which looked extremely delicate.

"Brother, this explanation is very complicated. You just need to know that the disease is caused by the invasion of some organisms that are so small that we cannot see. Moreover, this kind of creature can spread among the crowd through small insects such as fleas. This type of ordinary yellow soap is added with sulfur. It is a special soap. It can not only kill fleas and other insects, but also kill those small creatures that are the source of the disease. It is most suitable for you to use. In addition, the lotus-shaped soap is added with honey and some spices, which can be used by both men and women!" Zhao Yan explained with a smile.

Originally, Zhao Yan only planned to make ordinary lotus-shaped soap, but considering the poor sanitary environment after the flood, he specially made some sulfur soap. Not only did he use it, but every time he came back from outside, he also required sulfur soap to clean his body so as not to bring the disease home. However, this sulfur soap was made in a hurry and did not have time to make molds, so he could only make the simplest rectangle.

The Song Dynasty attached great importance to medical skills. The court had multiple official medical institutions such as the Imperial Medical Bureau, Hanlin Medical Officer Hospital, and Imperial Hospital. As long as scholars were scholars, most of them knew a little about medical skills. Fan Zhongyan said, "If you don't be a good minister, you will be a good doctor." This shows that medical skills are common among scholars in the Song Dynasty.

As the future successor of the Song Dynasty, Zhao Xu naturally knew some medical skills. However, in the traditional Chinese medicine theory he knew, epidemics should be caused by miasma, severe qi, and evil qi entering the body. However, Zhao Yan said just now that the epidemics were caused by an invisible small creature, which was obviously very different from the medical theory known to Zhao Xu. If it were in normal times, Zhao Xu had to ask clearly, but now the situation is urgent, he didn't have to ask too much. He immediately took soap and rushed to Tokyo without even eating.

Standing in front of the gate of the other courtyard, Zhao Yan looked at Zhao Xu who was leaving in a hurry, but couldn't help but shake his head. As the future successor of the Song Dynasty, Zhao Xu's impatient personality is not a good thing. After all, governing a country involves all aspects of interests and cannot be achieved overnight. As an emperor, not only must he be determined, but also cannot lack patience. I hope that Zhao Xu will realize this in the future and change his personality, which will be beneficial to him and the Song Dynasty.

When he was free, Zhao Yan hummed a small song with his hands behind his back and returned to the inner house with three steps. It was not yet noon, and Zhao Yan originally planned to go back to the room and draw a few strokes, but unexpectedly, when he just walked to the door of Cao Ying's room, he heard a burst of girl laughter from inside, including Cao Ying, Xiao Douya and Mixue.

During this period, the relationship between Cao Ying and Zhao Yan began to really ease. The two no longer faced each other in the tit-for-tat way like before, so when they heard the laughter inside, Zhao Yan walked into Cao Ying's room and found that the table in the living room was filled with boxes of soap. Cao Ying, Xiao Douya, Mixue and the other two sat around the table, whispering from time to time, making bursts of silver bell-like laughter. I don't know what they were saying?

"What are you doing? Why did you take out all the soap?" Zhao Yan asked with a smile. The raw materials in the soap workshop are limited and there are not many soaps produced. It is estimated that the table has been placed on all the production during this period.

"Prince, we and the fourth sister are discussing who should give soap to whom we should give to?" Xiao Douya immediately stood up and gave him a seat, and then ran to Mixue opposite him to sit down, so that Zhao Yan could sit with Cao Ying. Speaking of the relationship between Zhao Yan and Cao Ying eased, this little girl also put in a lot of effort.

When Cao Ying saw Zhao Yan coming in, he looked at him and immediately lowered his head, and did not stop Xiao Douya from giving up his seat. Zhao Yan did not refuse Xiao Douya's kindness, and sat down and asked again: "The raw materials in the workshop have not arrived yet. Is this little soap produced only by storing in the warehouse. Isn't it too little to give to people?"

As soon as Zhao Yan finished speaking, Cao Ying raised his head and said, "There are already a lot of soaps. We just counted it. In addition to the soap that the prince just asked King Ying to take away, there are 32 pieces left. This way, I can give it to thirty-two people. I plan to give it to the noble ladies and ladies with a relatively powerful influence in the city. With the effect of soap, these ladies will definitely praise them. At that time, they can use these ladies' mouths to spread the reputation of the soap. When the workshop can officially start construction, they will not worry about not buying it."

This is the first time that Zhao Yan discovered that Cao Ying actually has such excellent business talent and understands the role of advertising without any guidance. In fact, Zhao Yan gave Zhao Xu the soap before and asked him to take it back to the palace, which was the same idea as Cao Ying. As long as Zhao Shu, Empress Gao and others used soap, it would definitely spread among the nobles soon.

"This method is good, but does it seem too shabby to give each person a soap?" Zhao Yan then said. He is a prince after all, and the status of a noble lady who can let Cao Ying give gifts is definitely not ordinary. However, the gift he gave was just a piece of soap, which made Zhao Yan feel a little desperate.

"A piece of soap can be sold for at least ten cents of yuan, why is it so shabby?" Cao Ying asked with confidence.

"Ten...Ten ten cents?" Zhao Yan was almost frightened to the table when he heard this. Although the oil in Dasong is relatively expensive and alkaline noodles are not cheap, even if the raw materials are included, the manual and the largest packaging cost, a piece of soap will not be as expensive as a penny. But now Cao Ying is so lucky that he has set the price of soap to more than ten cents at once. He is not a princess, he is simply a bad-hearted and vicious businessman!

Seeing Zhao Yan's shocked expression, Cao Ying showed a proud smile and said: "You don't have to be surprised. The bath beans we usually use can be sold for 70% or 80% of money. Soap with better effect than bath beans, so of course it cannot be cheaper than bath beans. Otherwise, people would rather use bath beans than use the soap produced by our home!"

"Understand!" Zhao Yan's reaction was also quick. It turned out that suckers from ancient and modern times, both at home and abroad are all virtues. They only buy expensive ones but not the right ones. Those who are willing to spend seven or eight cents to buy bath beans will not care about spending a few more cents to buy soap with better results.
