The sedan chair to greet Fang Ziyi stopped at the back gate of the Forbidden City, she was not a court woman, and she had no orders, so she could only enter from here. Hearing that the old palace maid in the palace urged her to move, she straightened her clothes and restrained the wry smile on her face.

I didn't expect to be invited to the Forbidden City by the current queen...... And the queen's will is quite gentle, not an order, a real invitation. The excuse is also very tactful, saying that Princess Kunxing has heard of Yu Fang's name for a long time and wants to ask her for advice.

She was actually very reluctant to come here, before marrying Yu Guozhen, she only learned in a letter that Yu Guozhen had done a great career overseas, but after getting married, some things gradually came into her hands, and at this time she understood how big Yu Guozhen used to say lightly about "100,000 hectares of land"!

This kind of thing is a taboo in heaven!

After learning about Yu Guozhen's career, her first thought was not joy, but worry.

She is in a family of eunuchs, although her biological parents died early, she is sheltered in the family of her uncle, and she is very clear about some things in the court. She herself is not very interested in prosperity and wealth, but she is very concerned about some livelihood matters. For example, Yu Guozhen's technique of artificially cultivating shiitake mushrooms, she built her own greenhouse to test, and the result was a great success. These seemingly trivial things made her feel that there were many novel discoveries, and they also made her extremely interested in Yu Guozhen's practical learning.

In fact, if it weren't for Yu Guozhen's insistence, she would not have been willing to come to Beijing with Yu Guozhen, but would rather stay at home, do some "experiments" as Yu Guozhen said, and write "test reports".

"Fang Ziyi, a folk woman, knock on the queen......"

Just as she was pondering, she had already arrived in front of Kunning Palace, and after the palace maid who sang the salute had passed the ceremony, she soon heard the summons.

What surprised her was that Queen Zhou, who was the mother of the world, did not come to see her in a phoenix crown, but dressed as a family woman. Queen Zhou's appearance is only outstanding, but it is not stunning, when Fang Ziyi peeked at it, she found that her expression was very gentle.

If it weren't for her identity, she was afraid that she would have to come over and hold Fang Ziyi's hand and ask long and short questions.

"I frightened you a few days ago, and the court will give you an explanation for that matter, and give Yu Jimin an explanation." After a few words, Empress Zhou mentioned Fang Ziyi's assassination.

Fang Ziyi still had palpitations when she thought of that incident, but she pursed her lips and smiled, thanking Queen Zhou for her care, and for a while, the atmosphere was a little embarrassing.

Empress Zhou didn't know how to talk to this simple-looking and bookish girl, and the words she had spoken about meeting those noble ladies were obviously not needed by her. The easiest thing for a woman's family to get closer is to discuss their children with each other, which is also a topic that cannot be spoken, after all, Fang Ziyi and Yu Guozhen have only been married for a few months.

After pondering for a while, Empress Zhou asked, "Ziyi, I heard that there are more talented women in the Fang clan in Tongcheng, I don't know what books you read at home?" ”

Fang Ziyi was prepared for this question, and listed a bunch of books she was reading, among which there were no works familiar to Empress Zhou such as female commandments, but all works such as "Xu Xiake's Travels", "Physics Knowledge", "Compendium of Living Beings", and "Discussion on the Theory of Heavenly Evolution".

"The rest of the books, this palace has also heard of them, but this "Compendium of Living Souls", I don't know what kind of book it is?"

Empress Zhou is also a lover of reading, and her questions are to the point. Fang Ziyi's spirits perked up, and he said with a smile: "This "Compendium of Living Souls" is written by the Taoist Gui Quanzi, who once edited the "Compendium of Materia Medica" with Li Shizhen, the former physician of the Taitai Hospital, and has been monographing medicine for decades. The Compendium of Living Beings divides the living beings in the world into two major species: animals and plants......"

Gui Quanzi's "Compendium of Living Beings" was still a very shallow and even erroneous work in later generations, but at this time it was an epoch-making work, and Yu Guozhen contributed very little, but when he was chatting with Gui Quanzi, he felt that he could imitate the "Compendium of Materia Medica" to sort out all the living beings in the world. It took two years for Gui Quanzi to finally complete the first volume of the general outline of this work, which is not currently available on the market, but Yu Guozhen printed some of them first and distributed them as amateur reading materials for the home guard.

"How can it be said that this animal and the tree belong to the same source?" Queen Zhou was very interested in hearing this, no matter how virtuous she was, but life in the harem was still relatively boring, not only her, but also the little concubines around her also listened to it with relish.

Fang Ziyi's heart moved, and she thought of one thing: "Niangniang, hearing is false and seeing is believing, the concubine came this time and prepared a small gift for Her Royal Highness Princess Kunxing, and now she is outside." Niangniang can analyze with her own eyes whether the statement on the general outline of the "Compendium of Living Souls" is correct. ”

Queen Zhou heard that it was a small gift, and was hesitating to accept it, when Zhu Yujiao clapped her little hands and applauded. She also ran from Queen Zhou to Fang Ziyi's side, pulling Fang Ziyi's sleeve and thanking her repeatedly. This little appearance reminded Fang Ziyi of Zi Ning's childhood, and she had a better impression of her.

At least this little princess does not have the arrogance of a noble daughter of the heavenly family, and Queen Zhou is very well educated.

After a while, the little eunuch moved the gift box in and put it on a small table, Fang Ziyi asked to open all the doors and windows so that the light would be better, and then moved the things in the gift box out.

This thing is a microscope.

After spending a lot of time researching transparent glass, the glass industry is a key research direction for Yu Guozhen. In this era, this is an exclusive business, and even Europeans cannot compete with Xinxiang in Daming. And Yu Guozhen is also very clear about the value of glass products in military and scientific research, such as telescopes and microscopes.

"What is this?" Zhu Yujiao asked curiously when she saw this thing composed of steel and glass.

"This is a microscope, made by my father-in-law."

Fang Ziyi proudly said the words "My family's father-in-law", Queen Zhou pursed her lips and smiled slightly, sure enough, that Yu Jimin was a good topic for conversation.

"Microscope? What's that for? Zhu Yujiao's face was full of puzzlement.

"It's to make small things look bigger, this microscope can magnify things a hundred times!"

"Huh?" Queen Zhou's curiosity also rose, she was a little surprised, Fang Ziyi would definitely not lie to her face, then this gadget composed of some iron pipes and parts really has such a magical use?

Fang Ziyi said to Queen Zhou: "Niangniang, please send someone to pick a leaf and take a strand of hair." ”

After a while, someone plucked a leaf from the imperial garden, and the hair was even simpler, and it was directly plucked from the head of a little palace maid, which made the little palace maid tremble. Fang Ziyi put the leaves under the microscope, and after adjusting them, she said to Zhu Yujiao: "Her Royal Highness Princess, can you take a look?" ”

Zhu Yujiao really wanted to go over to see it, but Queen Zhou grabbed her and said with a little worry: "This thing...... Is it dangerous? ”

"Niangniang, please rest assured, and watch the concubine try it." Fang Ziyi leaned over to the microscope and looked at the leaves lining the copper plate, after magnifying more than a hundred times, the leaves were extremely clear, and even the cells could be observed. Although Fang Ziyi has seen it more than once, every time she sees it, she still can't help but be dazzled and sigh at the mystery of creation.

Whenever this happens, she is very glad that she is married to Yu Guozhen. If it weren't for Yu Guozhen, where would she see such a mysterious microcosm?

Seeing that there was no problem with her trial, Queen Zhou still asked a palace maid to try it out, and after the palace maid cautiously approached it, she exclaimed: "Really...... Really, it's huge! ”

This time, Zhu Yujiao couldn't hold back any longer, she squeezed away the little palace maid, moved a brocade stool by herself, and climbed onto the observation platform. The palace maids and eunuchs next to her hurriedly supported her, but by this time she had already come to the microscope and exclaimed in an uproar.

This microscope was originally invented by the Dutchman Hooke, and when Hooke was only four years old, Yu Guozhen snatched his great invention. How Hooke made the lenses has always been a mystery, with the grinding techniques at the time, he could not have made such delicate lenses, Yu Guozhen just knew his secret, he was nothing more than using the molten glass itself tension. Knowing this principle and doing hundreds of tests, you will naturally have the lenses you have now.

Zhu Yujiao watched and cheered, first looking at the leaves, then at the hair, and then touching everything and stuffing it under the microscope, even her own little hands to try it. Hearing her shouting and shouting, she was extremely happy, and Queen Zhou's favor for Fang Ziyi increased greatly, and she couldn't help but lean up to take a look, and then said in great surprise: "Yu Jimin is really skillful, he can make such a delicate thing!" ”

"In fact, there is nothing magical to put it bluntly, and now people are sailing on the sea, and they mostly use clairvoyants to look into the distance, and it is said that this thing is also used in the army. The microscope is just made according to this principle, and it should not be praised by the mother. ”

Although Yu Guozhen was very happy to be praised to Fang Ziyi, she was still very calm, she knew that although skillful hands can be admired, they can also become the cause of trouble at some point. For example, if there is an old stubborn old example of the carpenter emperor's apocalypse, saying that this is a miracle and silver trick will cause the plaything of the Son of Heaven to lose his mind, then his gift this time not only did not help Yu Guozhen to marry the royal family, but caused trouble.

"Wow, there are so many bugs in the water!"

Empress Zhou heard the meaning of Fang Ziyi's words, and was about to say with a smile, when she suddenly heard Zhu Yujiao shouting. It turned out that Zhu Yujiao was tired of seeing everything else, so she asked the palace maid to go to the fireproof water tank in front of the main hall to get some water.

Empress Zhou leaned over to take a look, and her face sank: "What's going on, ...... in the water How can there be so many bugs? ”

She was not angry with Fang Ziyi, but at those eunuchs and palace maids. A eunuch replied, "The slave and maid will go and order, and change all the water......

Fang Ziyi said: "Niangniang, the concubine has also seen it and found that there are insects in almost all the water, but if the water is boiled, the insects will die, and drinking it will not hinder it." ”

Queen Zhou was suspicious, and called people to call for clean well water, as well as the spring water of Yuquan Mountain, and after trying it one by one under the microscope, she said with emotion: "I see, Kunxing, you can drink water in the future, and you can no longer drink raw water!" ”

Zhu Yujiao was also frightened by those insects, and nodded when she heard the words, she tilted her face and looked at Fang Ziyi: "Are these truths taught to you by that very skilled Yu Jimin?" Queen Mother, can you invite Yu Jimin to teach her as well? ”

The child's words, Fang Ziyi did not go to her heart, but Queen Zhou was moved in her heart.
