In addition to Shuntian Prefecture being directly operated by Huangrentang Pharmacy, Hebei and other places have adopted a franchise model, plus there are exactly ten of them in Shandong, which brings Zhu Cixuan a franchise fee income of more than 100,000 taels of silver.

This money is just used to expand the production of patent medicines. With the scale effect, Huangrentang Sheng medicine procurement bargaining power has been further strengthened.

In this way, the simple charge that was originally not profitable now has a profit ranging from a few to dozens of cents. After the quantity increases, the profit is very objective, almost equivalent to the fine charge.

After training in these franchise stores, they mainly value their drug sales ability. Zhu Cilang has a golden sign in hand and naturally has to do his business.

First, they were asked to open a counter to sell Royal Selected Raw Medicine. These medicinal materials were all good medicines after strict selection and inspection. With the royal name, they would definitely attract wealthy families.

In addition to medicines, they are also responsible for selling secret health products in the palace. Zhu Cilang knew that health products in later generations could be a big market. If you don’t cheat these rich people out of more money, how can Zhu Cilang help the poor in the future!

What's more, the health care formula provided by the imperial doctors is really effective, and it is much more real than the ones who are purely fooling people in later generations.

Therefore, these franchise stores do not have to worry about not having money to make money, and Zhu Cilang also allowed these raw medicines, finished medicines and health products to expand the market and expand sales channels.

As for the issue of the imperial doctor, the emperor spoke. Zhu Cilang naturally asked the imperial doctors to draw personnel to various imperial halls for consultation every day. In order to increase the enthusiasm of the imperial doctors, Zhu Cilang also specially established a reward and punishment system.

If you have the imperial destiny and money, these people will naturally not say anything. As for the dispatch of imperial doctors in the franchise store, Zhu Cilang ordered the Donggong Diocese Pharmacy to recruit famous doctors in the capital. Since these people work in the Donggong Diocese Pharmacy, they are actually under the jurisdiction of the imperial doctors, or they can be said to be imperial doctors.

If you don’t play the edge, you can’t find so many imperial doctors to patrol them. With Huangrentang having a stable source of income, Zhu Cilang can start research on the plague.

If you rely on this era to discover it yourself, you will probably have no hope. Zhu Cilang has limited knowledge of the plague and will not be able to treat it.

But he at least knew that this thing was transmitted through various channels such as rats and fleas and human-to-human transmission. As long as you do a good job in killing rats and fleas, the plague can still be prevented and controlled.

At present, the epidemic is mainly concentrated in Taiyuan, Luliang, Datong, Shanxi and other places. However, as Shanxi people scattered and fled to avoid the plague, the plague further spread, entering Shaanxi to the west and Hebei to the east, and eventually spread throughout the Ming Dynasty.

The wise rulers and ministers of the Ming Dynasty do not know the harm of this plague yet. What Zhu Cilang can do is to improve their ideological understanding first.

So today Zhu Cilang summoned Johnson from the Imperial Heavenly Prison. If you want to explain the harm of the plague, nothing is more vivid than using the Black Death in Europe.

Johnson Chan was very happy to hear that the prince of the Ming Dynasty was summoned. Although he had been working hard to preach and learned Chinese and Chinese culture for this purpose, Christianity did not spread smoothly in the Ming Dynasty. In his opinion, this was the reason for the lack of belief in a higher-level figure. Today's summoning is an opportunity!

Zhu Cilang looked at Zhu Zilang wearing Ming Dynasty official uniforms and could not say that he liked or disliked except for being awkward. Under the premise that the Han people could not be loyal to the Ming Dynasty, a German man became insignificant when he experienced the Ming and Qing dynasties.

Zhu Cixuan asked loudly: "Joewon, are you German?"

John Thon bent down to pay homage: "Return to the words of the Prince, I was born in Cologne, Holy Rome, and was a Germanic man, but I later served Jesus and became a servant of God."

Zhu Cixuan didn't have time to listen to him talk about Christianity, so he asked directly: "There was a plague in Shanxi, Daming. I heard that similar plagues broke out in Europe. Tell me what you know."

When Joshua Chan heard Zhu Ciyang pull the topic apart, he felt a little regretful, but he still patiently answered Zhu Ciyang's question:

"Return to His Highness the Prince, in 1347, the Mongols attacked the Black Sea port city of Kafa in 1347 and introduced the plague into Europe. From 1347 to 1350, more than 30 million people died in Europe in three years, and then half of the Europa were killed because of the plague."

Zhu Cilang nodded. This data was already scary enough, but only European data could not explain the problem. The Ming Dynasty needed to have its own statistical results on the plague.

When Tang Ruowang saw Zhu Cilang without saying a word, he continued, "We think this is the Lord's test to the world. Only by believing in the Lord can you escape the judgment of the plague..."

Zhu Cixuan waved his hand: "I heard you wrote a telescope and said, "Do you know a microscope? I remember Galileo used it, would you make it?"

Johnson Chan nodded: "Of course! If His Royal Highness is interested, I can make a one to deliver to His Royal Highness."

Zhu Cixuan greeted Xiao Weizi: "Little Weizi, take Tang Johnson to the jewelry workshop in the imperial shop, and let the craftsmen who grind the gemstones learn to make telescopes and microscopes according to Tang Johnson's guidance."

Johnson Chan shook his head: "Your Highness, this is not possible! You need to have glass to make telescopes and microscopes, but the Ming Dynasty does not have glass, so it can only be transported from the distant Europa."

Zhu Cixuan saw that he wanted to mock him, but thought about why he couldn't get along with the money, so he waved his hand: "You go, someone will naturally send the glass to you."

After leaving, Zhu Cilang found a piece of paper and began to write the production process of traveling through the Three Treasures. The glass is soda ash, quartz stone and lime. The key is to purify and remove impurities in the process. Zhu Cilang only remembers to grind it into powder and use iron-absorbing stone to suck off the iron.

The production of soap requires a lot of oil. Let’s put it aside first and wait until the peanuts are planted on a large scale.

Perfume can be made on a small scale, just adding a product to the Royal Store.

Then Zhu Cixuan began to produce a plague statistics table. Li Ruolian was arranged to go out for more than two months. I think he should be back soon. Without this, he really couldn't find a suitable staff in such a long-distance work.

After thinking for a while, Zhu Cilang slapped his head, why did he always think about fighting alone? Isn’t it still there for me? I asked Chongzhen to ask him to send someone to help.

Looking at the sky, Chongzhen was probably reviewing the memorials at this time, and Zhu Cilang sat down and headed towards the Qianqing Palace.

When I arrived at the local eunuch, I told him that Zhu Cixuan came in and saw that Chongzhen was not working, but was reading a lot of books.

Seeing Zhu Ciyang coming, he looked up and asked, "Come on my son, come quickly, I will check the history books. The duration of this cold season is uncertain, sometimes decades and sometimes more than a hundred years. How long do you think our Ming Dynasty will last this time?"

Zhu Cixuan leaned over and took a look. Chongzhen was looking at the Later Tang Book. Zhu Cixuan thought for a while and said, "According to the existing data analysis, this cold season will last at least for more than 30 years."
