Although Cao Qi and the others knew that Zhao Yan could not make glass again, they finally agreed to the conditions proposed by Zhao Yan. As long as Zhao Yan took out the method of making glass mirrors, then 30% of the profits of Taoist sect in glass mirrors in the future will belong to Zhao Yan, which also made Zhao Yan very satisfied and wrote out the method of making glass mirrors on the spot.

In fact, the main method of making glass mirrors is electroless silver plating, but unfortunately it requires silver nitrate. Zhao Yan couldn't find it at all, so he could only use another primitive method, which is to paste tin foil, and then pour mercury between the tin foil and the glass. After silence for a period of time, part of the tin will be dissolved by mercury, and then attach to the glass. Then apply a layer of paint to prevent mercury from falling.

Of course, the above method has a big disadvantage, that is, bubbles are easily generated when making mirrors, so that large mirrors cannot be made. The Venetians in previous lives used this method to make mirrors, which made the larger the mirror, the more valuable it was, and even a book-sized mirror would be priceless.

However, it doesn’t matter if there are shortcomings. As long as you can make a mirror, any technology is imperfect when it first appears, and people need to use wisdom and time to improve it bit by bit. Therefore, after Cao Qi and his team got Zhao Yan’s method of making mirrors, they immediately felt like they were treasured. Several people immediately organized human experiments as quickly as possible. As long as the experiment was successful, they would immediately establish a glass mirror workshop. You must know that they had made a lot of money by selling glassware before. If there were glass mirrors, they could definitely bring greater benefits to Taoist sects.

It is also worth mentioning that Daomen has opened a glass workshop near the capital. It is said to be extremely large in scale, with nearly a thousand craftsmen alone. And it has begun to produce glass. Now all the glass products flowing out of the surface of Beijing are from there. If the manufacturing method of mirrors is feasible, they will also build another mirror workshop near the glass workshop.

After solving the problem of glass mirror, Zhao Yan listened to the skillful Liu to introduce the manufacturing progress of the microscope. As well as the problems encountered and solutions, overall, this Song Dynasty version of the microscope should be feasible in theory, but the sample has not been completed yet, and no one can guarantee the effect.

Zhao Yan spent the afternoon in the microscope. In addition to solving some problems in microscope manufacturing, he was also very interested in Cao Qi and his friends expanding the Taoist myth system, because in his opinion, this was simply the Taoist sect fabricating the background structure of a myth novel, and also gathering a large number of elites in the Taoist sect. So he really wanted to see what kind of myth system would he create with so many people's imaginations?

But it is a pity that although Zhao Yan is Cao Qi's son-in-law and has a very close relationship with the Taoist sect, it's a pity that he is not a Taoist sect after all. According to the agreement between Cao Qi and Zhang Sizong, Liu Hunkang and others, he must be a Taoist sect to participate in this matter. Therefore, it is easy for Zhao Yan to know the progress of this matter. That is to say, joining the Taoist sect does not necessarily have to be a Taoist priest, just be a lay Buddhist, but Zhao Yan does not want to join any Buddhist sect. So he had to give up in the end.

Seeing the sun was west, Zhao Yan took Shu'er to Cao Qi and others and said goodbye. Then he bought a lot of snacks and snacks at the market outside the door to take them back. Xiao Douya and Mixue's girls liked these things the most.

When Zhao Yan returned to the other courtyard, Cao Ying and Princess Dening had just finished playing mahjong. Among them, Princess Dening, Princess Bao'an and Princess Shoukang were all happy, but Cao Ying was a little unhappy. Zhao Yan saw this and immediately stepped forward and asked, "How much did you lose today?"

"Hehe, Sister Ying'er's luck is not good today. She only lost out of the four. Today she happened to lose 30 knots." Before Cao Ying could speak, Princess Dening smiled and said first. Judging from her appearance, it is estimated that most of the 30 knots Cao Ying lost fell into her hands.

"Haha, it's only thirty cents, it doesn't matter. Today, my husband, I knocked on a big income from the Taoist door, which is definitely more abundant than the Cao family's honeycomb coal business!" Zhao Yan laughed and said with a loud laugh. Thirty cents are definitely not a small amount. It is already a huge sum of money for ordinary people, and it is also a pocket money for Cao Ying and the others. However, today Zhao Yan and the Taoist party negotiated a glass mirror business, so they naturally didn't care about this little money.

When Princess Dening and the others were shocked when she heard Zhao Yan's words, Cao Ying even rushes to ask: "What business do you plan to do with the Taoist sect? You actually make more money than the honeycomb coal in our Cao family?"

You should know that the Cao family defeated the Gao family in one fell swoop with honeycomb coal, thus dominating the coal supply in the entire capital. Although later, for the sake of the general, they distributed part of the coal supply to the Gao family, they still occupied the majority of the coal industry in the capital. The money they earned every year was also astronomical. Zhao Yan accounted for more than 20% of it. This profit alone was enough to make the royal family a rich man among the nobles. So when Cao Ying heard Zhao Yan say that it was more profitable than honeycomb coal, he was a little suspicious for a while.

"Hehe, this is a coincidence. If I hadn't happened to meet today, I would have almost forgotten that there was such a profitable business!" Zhao Yan said and told the story of the glass mirror.

As for the glass mirror, except Princess Dening, everyone else had seen it with their own eyes. It was the small mirror on Zhao Yan's microscope. Although it was only the size of a copper coin, it could reveal the tiny bits of a person's illumination. Even Cao Ying wanted to take this small mirror several times as if he had given the mirror, but if the mirror was given to her, the microscope would not be used, so even if Zhao Yan agreed, Cao Qi and others would never agree.

"Husband, after the glass mirror you mentioned is made, can it really be like the mirror on the microscope, and can it really make people look very clear?" After listening to Zhao Yan's story, Cao Ying immediately rushed to ask. She had been coveting the glass mirror on the microscope for a long time. If it weren't for her grandfather's reasons, she would have snatched it.

"Of course, but in terms of clarity, the mirror made with Taomen's current technology may not be as good as the small mirror on the microscope, but it can be made larger and more beautiful. After the sample is made, it will be given to my wife and some sisters for trial first!" Zhao Yan immediately said very well. He knew Cao Ying's thoughts better than anyone else.

"That's great, thank you husband (third brother)." As soon as Zhao Yan finished speaking, Cao Ying, Princess Bao'an and others immediately said happily, as a woman, no one can refuse a clearer mirror.

"Third brother, what are you all talking about? Why can't I understand what the glass mirror is going on?" At this time, Princess Dening said in confusion. She had never seen a glass mirror before, so naturally she didn't know what the glass mirror represented.

"Mom, a glass mirror is a mirror that is much clearer than a bronze mirror. My uncle wants to cooperate with those Taoist priests to make it, and it seems that he can make a lot of money." At this time, Shu'er spoke first. When Zhao Yan and Cao Qi discussed the glass mirror, he had been following him, so naturally he knew better than anyone else.

Princess Dening's eyes lit up when she heard her son's explanation, and then she blamed Zhao Yan: "Third brother, you are really, why don't you think about our family first for such a good business?"

Zhao Yan has long heard of Princess Dening’s housekeeper Youdao, but he replied helplessly: “Sister, as the name suggests, glass must be used when making glass mirrors, but now all the manufacturing of glass is in the hands of Taoist sect, so even if I know how to make glass mirrors, I can only cooperate with them.”

Princess Dening was not an unreasonable person. She understood Zhao Yan's words very well, but then she said, "It's all for the manufacturing of glass mirrors, but in the future, the third brother will have to help her sister make some glass mirrors. If this thing is transported to the south or overseas, it will definitely be worth tens of thousands of yuan."

"Haha, this is fine. After the glass mirror is officially produced in the future, I will definitely give you one to my elder sister!" Zhao Yan immediately patted his chest and promised that Zhao Yan was also very interested in Princess Dening's shipping power. Unfortunately, there are two powerful enemies, Xixia and Beiliao outside the Song Dynasty, which really makes him have no time to take care of overseas affairs.

"Okay, I'm worthy of being my own brother. At that time, my sister will not forget to give you dividends to your third brother!" Princess Dening said happily at this time.

In the past two years, Princess Dening has done a lot of business in the south and overseas, and it is also thanks to Zhao Yan. After the honeycomb coal was created, she was the first to promote it in the south. Later, there was the soap trade, which allowed her to successfully open up the markets in the south and overseas, and almost doubled the business in her hands. This time, the business with the help of glass mirrors can definitely make her business bigger.

"And I, there are also a batch of mirrors in my store!" At this time, Princess Shoukang also shouted. After Cao Song's help, her store finally turned a profit. However, she had the temperament of fishing for three days and two days to dry the net. Usually, she would go to the store only when she occasionally remembered it. Today, she heard the conversation between Princess Dening and Zhao Yan, and then she remembered her own store.

"No problem, no one will lose two sisters." Zhao Yan promised again. From the performance of Cao Ying and the three sisters, he seemed to have seen the scene of the glass mirror being snatched after it was launched.

Time flies quickly. As the two-month summer vacation is about to pass, Zhao Yan has also begun to prepare for the new courses and enrollment of the next semester, but there is one thing that makes him very worried.
