Early the next morning, Chang Wei summoned the three daughters and Ma Yuan and taught them the Nine Yin True Scripture and the Nine Yang Divine Skills. Pen % fun % Pavilion www.biquge.info

Ma Yuan, who has been fighting on the grassland for most of the year and has experienced life and death every day, has reached the realm of invulnerability to the fourth layer of internal strength, and Yan Ruyu is about to touch the bottleneck of invincibility, Xue Qian's martial arts are better than nothing, but it is always good to have more self-defense, Tang Shuxue is a little worse than Ma Yuan.

With the peerless magic skills of Nine Yin and Nine Yang, presumably their strength can skyrocket, but as for Chang Li, it is unnecessary, and I don't know how this kid's martial arts are practiced, in short, they are about to catch up with Yan Ruyu.

After being busy with his own people, Chang Wei inspected the laboratory and factory non-stop, and the current person in charge of Zhenjiang Laboratory is Bi Denghan, Bi Dengfu, Bo Jue, and Sun Yunqiu. Erbi has been here since the beginning of the laboratory, and he is the oldest.

Sun Yunqiu was born in the family of the eunuch, moved to Suzhou with his parents when he was young, he was very bright since he was a child, and at the age of thirteen he was a talent in Wujiang County. Diligent and studious, he loves Western learning, and is good at measurement, mathematics, and geometry. Skilled in instrument making, in order to calibrate the chiming clock, he made his own "natural sundial", which is an instrument that determines the time according to the shadow of the sun, and is very accurate.

Based on Matteo Ricci's knowledge of geometry and physics, Sun Yunqiu finally mastered the technology of "grinding tablets to light" through the practice, accumulation and exploration of his own production, creatively grinding lenses with crystal materials, and also creating a drag car for grinding lenses. He can match glasses according to the age and disease of patients with eye diseases, and can also "spend by age, and divide by land", so that patients can be equipped with lenses suitable for their eyes.

On the basis of grinding convex lenses and concave lenses, he used crystal stones to grind into eyepieces, kaleidoscopes, mandarin duck mirrors, magnifying glasses, illusion mirrors, night mirrors, telescopes and other optical instruments, and also wrote a book "Mirror History", and the ink crystal glasses that Chang Wei wore before were produced by Sun Yunqiu.

Bo Jue was a friend of Sun Yunqiu's teacher and friend, but because of repeated failures, he changed his studies to astronomy, mathematics and mechanical engineering. Pay attention to practice, configure various tools and equipment, and repeatedly develop. He once helped the imperial court to make copper cannons, and the copper cannons made by him had high precision, advanced structure, and were equipped with clairvoyant mirrors on the cannons, which improved the hit rate.

He also made waterwheels, firearms, mines, crossbows, and other instruments, and also made armillary spheres. He is the author of many works, such as "The Delusion of Asking the Heavens and the Northwest of the Northwest" and "The Diagram of the Armillary Sphere", "The Measurement of the Heavens in the Sea", "The Colorless Discrimination of the Celestial Bodies", "The Identification of the Heavenly Shape in the North and the South", "The Theory of Guarding the Heart", "The Theory of Gewu Geodesy" and many other works. Its superb mechanical technology has a great impact on the development of the manufacturing industry in Susong.

In the second half of the year, Sun Yunqiu and Bo Jue were shocked when they saw the goods of the Zhenjiang factory, especially the steam engine, so they were deceived by Xue Qian so naturally.

In the afternoon, Chang Wei and Tang's mother Dongfang Qingyun, Yan Ruyu, Ma Yuan, Chang Li, and No. 100 Jinyiwei rode and drove, bringing some gifts to Nanjing to participate in tomorrow's martial arts conference.

Tang Shuxue is not going this year, she is sweetly preparing for her wedding, and the personnel of the Seven Seas League, under the leadership of Qiu Feng, have already arrived in advance.

The Seventh Son of the Big Dipper, Han Chai, and Wang Ziyong protected Wuding in Qinglongwei, and the greedy wolf and the broken army led the Zhenhai Gang to participate in the guise of Ni Ling and Ni Zhen, and Luo Yun did not come.

Don't think that the Seven Seas Alliance will be weakened in this way, on the contrary, Liu Jingting, a big master, as well as Feng Lu, Leng Xin, Guo Jinmi, and Chu Qijue, have openly joined the Seven Seas Alliance, plus Chang Wei, whose strength has skyrocketed, this year's Seven Seas Alliance will be even stronger.

Zhenjiang to Nanjing waterway 100 miles, the land route is closer, as soon as they arrived at Yanziji, Chang Wei first went to the Tangmen station with his mother-in-law to meet his father-in-law Tang Xingtian, chatted with Tang Jinyi for a few words, and then, other things were left to Yan Ruyu and Ma Yuan, and he first went into the city with gifts to meet Wei Guogong.

Chang Wei can get to this point today, Wei Guogong has made a lot of efforts, and he can't forget his roots, not to mention, he hasn't seen Xu Shuyi for a year, and Chang Wei still misses it very much.

The news of the Wei Mansion in Nanjing is very well-informed, and when Chang Wei arrived outside the mansion, Xu Hongji, Xu Wenjue and Xu Shuyi and other cadres were already waiting at the gate.

Xu Shuyi still has that graceful and elegant appearance, and when she saw Chang Wei, the undisguised longing and appreciation in her eyes were revealed for the first time.

"The so-called confidante, that's it. ”

As soon as the thought in Chang Wei's mind turned, Xu Hongji greeted him with a big smile, "Hahaha, Qin Guogong, the old man has been waiting for a long time." ”

The first family of the Ming Dynasty came out to welcome them collectively, which was already very glorious, and with such a formal title, Chang Wei was a little scared.

Hurriedly lowered his posture and greeted him, "Grandpa Xu, how can this be done? How dare you work in the Gonggong Mansion and torture the boy." It's business as usual, you still call me fearless, okay? Otherwise, I won't dare to come in the future. ”

"Hehe, how can that be done? On the title of Qin Guogong is still above Wei Guogong, the old man can't help but treat each other solemnly. ”

Since Qin Shi Huang unified the six countries, the title of Qin is the most noble, otherwise the emperor would not have gone on a hunger strike with his ministers for this title.

"What's not to do? The kid can have today all thanks to Grandpa Xu's help, no matter how high my status is, how big the official is, in front of my grandfather, I am a nephew, a junior, and I will never dare to be on an equal footing with you. ”

Maybe it's because he's low-key, or maybe it's because he is careful about family etiquette, Xu Hongji insists on treating Chang Wei as an equal, but Chang Wei insists on depreciating his identity, and the two of them are deadlocked at the gate.

The whole family of the Wei Guogong Mansion was watching at the door, and they really didn't know how to interject, so they finally relied on Xu Shuyi to persuade them, "Father, fearless, don't be humble to the two of you, it's winter, it's cold outside." ”

"Yes, yes, or Sister Shuyi is right, grandpa, please hurry up and invite first, I came from Zhenjiang, Shuimi came up to the house without teeth, and it is only right to entertain me. ”

"Hey, the old man thought that Qin Guogong was coming to visit me, but it turned out that he was here to mix rice. ”

Xu Hongji laughed, and finally entered the door one step ahead.

After entering the mansion, Xu Hongji didn't adhere to those etiquettes, so he could have a good chat, and after a meal, Chang Wei took the time to ask Xu Shuyi how she was studying in the dark.

Xu Shuyi did not shy away from leading him into the courtyard where she lived to see the research results.

As soon as she entered the back room, when Chang Wei was thinking about how to take advantage of it, Xu Shuyi took the initiative to throw herself into her arms and give her a long fragrant kiss.

Chang Wei was a little uncomfortable, and smacked his mouth, "Sister, today is really different from the past." ”

Xu Shuyi replied as a matter of course: "I haven't seen you for a year, I miss you." Well, I've dreamed of you several times. ”

This is the mature Xu Shuyi, undisguised, not a little pretentious, not a little profligate, it seems that everything is so taken for granted, as if she feels ashamed if she doesn't say so.

Chang Wei asked with a hippie smile, "Is it a spring dream?"

Xu Shuyi tilted her head and thought for a moment, "Well, there are three times." ”

Just when Chang Wei wanted to get into trouble, she pulled him into a small room with a smile, "Come and see my results this year." ”

Seeing the two things Xu Shuyi showed, Chang Wei was taken aback, is this a diorama and a kaleidoscope?

The so-called diorama is a kind of game equipment, the box contains a picture, there is a magnifying glass on the box, and a large box with a shading light is put on the outside, and there are several small holes on one side of the box for the eyes to come up to see, and the magnified picture can be seen by using the camera obsca operation according to the optical principle. This thing appeared before the movie, and it was full of foreign customs. That's why it's called a diorama, but I didn't expect Xu Shuyi to get this kind of thing out now.

The kaleidoscope is also an optical toy, as long as you look at the eye of the tube, a beautiful "flower" will appear. Turn it a little and another flower pattern will appear. Constantly turning, the pattern is also constantly changing, so it is called "kaleidoscope".

The pattern of the kaleidoscope is reflected by glass mirrors. It is composed of three glass mirrors to form a prism, and then put some glass fragments of various colors at one end, these fragments are reflected by the three glass mirrors, and a symmetrical pattern will appear, which looks like a blooming flower.

As the angle of the mirrors in the triangular lens changes, so does the number of images, and the images overlap to form various patterns, which can be seen by turning the kaleidoscope continuously. What's even more interesting is that once a pattern disappears, it takes centuries to turn for the same combination to appear, so every moment is worth appreciating and every second is worth cherishing!

"Great, perfect!" Chang Wei exclaimed as he watched, "Shuyi, how did you come up with these two things? Oh my God, you're such a genius!"

"Is it?" Xu Shuyi didn't seem to realize that she had created something great, "This is according to your train of thought, that camera machine is too difficult, and it can't be done yet, I made these two gadgets by groping, Sun Yunqiu and Bo Jue helped me a lot." ”

Sun Yunqiu and Bo Jue? The two optical experts worked together with Xu Shuyi to make this kind of thing appear in advance, although it was very unexpected, but it was not too strange.

Suppressing his excitement, Chang Wei affirmed: "With the experience of manufacturing these two things, it will be of great help to create a device that automatically reproduces the scenery of the world without brushes and paints in the future." ”

A device that automatically reproduces the scenery of the world without brushes and paints, Chang Wei's "envisioned camera" is also the research direction he set for Xu Shuyi.

Xu Shuyi has already found the key problem, "Everything else is easy to say, but it is too difficult to find a material that retains the image." ”

With the help of the system, Chang Wei knew the principle of Daguerre's invention of the camera: its basic idea was to expose a copper plate with silver iodide on the surface, and then steam it with mercury vapor and fix it with an ordinary salt solution to form a permanent image.

"Don't worry, the Chang'an laboratory is researching some chemicals, and these materials will come out in a few years. Suddenly, Chang Wei's words changed, "Great inventor, do these two things have any names? They can make a lot of money, how about it, are you interested in partnering to open a factory?"

"I don't have a name, I've only made these two finished pieces. Xu Shuyi is not interested in making money, "If you want to make it, I can teach Sun Yunqiu and Bo Jue." ”

Chang Wei snapped his fingers, "Then it's called Jinling Mirror and Kaleidoscope, and if you make money, we'll be half of each of us!"
