Gu Yingxiang rode his horse all the way, carrying a set of pulleys in his hand. He is a frequent visitor to Wang Yuan's house, and he can go directly to classrooms, laboratories and meeting rooms without notice.

In Jinyiwei's calm and solemn Gu experience, he was as happy as a child with a toy at the moment, and shouted: "Ruoxu, I have completely verified the lever experiment you mentioned, and I have made a set of pulleys by myself!" ”

"Congratulations!" Wang Yuan didn't raise his head.

Gu Yingxiang ran over and saw that Wang Yuan and the two craftsmen were busy working, and there were a few drawings scattered next to them, and he couldn't help asking, "What experiment is Ruoxu doing?" ”

Wang Yuan smiled: "You'll know when you make it." ”

Please ask the merchant to go to Yanshen Town to invite craftsmen, but there is no news yet, and the glazed official kiln does not know when it will be able to make transparent glass. Wang Yuan can't just wait stupidly, right? Simply invite craftsmen from the capital to polish concave lenses and convex lenses with crystal.

Natural colorless crystals, also have vacuoles or bubbles, only high-quality ores meet the requirements.

Gu Yingxiang squatted down and asked, "Is this glass?" ”

Wang Yuan nodded and said, "Yes, it's glass." ”

This glass is not the other glass.

In the Ming Dynasty, glass, Poli, water jade, jade ying, water essence, water blue, quartz, crystal jade, Bodhisattva stone, all express the same thing, that is, natural crystal!

Glass is crystal, and crystal is glass.

Gu Yingxiang squatted beside him curiously, the two craftsmen had already ground to the final process, and were using felt to dip the tin powder and rub it repeatedly on the surface of the crystal.

In ancient times, there was no sandpaper, how to polish a smooth copper mirror? That is, mercury doped with tin dust to grind.

When the tin is below 13.2 degrees Celsius, it will change from white metallic to gray powder, and the lower the temperature, the faster the conversion, and the copper mirror can be ground flat and smooth with this powder.

After grinding for another two hours, the craftsmen cleaned the crystal and respectfully handed it over to Wang Yuan.

Wang Yuan had already prepared a wooden cylinder, buckled the two crystals in the card slot, and wrapped the cylinder with a rope to fix it. He raised the binoculars, looked at the treetops in the distance, and then handed it to Gu Yingxiang: "Brother Gu, look." By the way, the two-section tube can be retracted, and you can adjust the distance yourself. ”

Gu Yingxiang was confused, and curiously observed the object with a telescope. At first, the focal length was wrong, and he tried to stretch the lens barrel, and suddenly a clear picture appeared. The treetops more than 100 steps away seem to be close at hand, and even the bird's nest on the tree can be seen clearly!

"What is this?" Gu Yingxiang was shocked.

Wang Yuan smiled: "Clairvoyant Mirror." ”

"How is it?" Gu Yingxiang has been with Wang Yuan for two months, and he already has scientific thinking, and he will always ask the principle when he encounters novel phenomena.

Wang Yuan said: "The principle of optics. ”

Gu Yingxiang was eager to try: "Teach me quickly!" ”

The telescope made by Wang Yuan belongs to the Galilean telescope, which consists of a concave lens and a convex lens.

Immediately, Wang Yuan talked about what reflection, refraction, focal length, and focus were, and Gu Yingxiang was stunned when he heard it.

Half an hour later, Gu Yingxiang was shocked and said: "If you make a clairvoyant lens with a strong enough spotlight effect and a long enough focal length, wouldn't you be able to see Chang'e in the Moon Palace?" ”

Wang Yuan laughed: "Not only can you see Chang'e, but you can also see Wu Gang, maybe Wu Gang is roasting the jade rabbit and eating it." ”

Gu Yingxiang asked: "How much is this clairvoyant, I bought it!" ”

Wang Yuan said: "Then you have to wait first, this clairvoyant mirror is dedicated to Your Majesty, and I will give it to you when the second one is made." ”

Both craftsmen were employed by Wang Yuan for a long time, with a fixed salary of two taels of silver per month, and for each qualified lens polished, they were rewarded with another penny of silver. Moreover, Wang Yuan also helped them cope with forced labor, which is the most attractive place for craftsmen.

Artisans rely on their crafts to eat, why are they living so miserably? It's because I have to serve regular forced labor, and I can't make a few dollars from exhaustion, and I mess things up and even lose money.

Wang Yuan continued to teach Gu Yingxiang about optics, while the craftsmen continued to grind the lenses, and he planned to send the telescope to the leopard room tomorrow.

The football stadium is building spectator seats, and the official game will be available next month, just in time for Zhu Houzhao to watch the game with a telescope.

The Qianlishen Mirror used by the emperor is no problem to sell for a hundred taels, right? No, it has to be sold for at least three hundred taels, which is cheaper than the lantern.

Two or three pairs can be shipped every month, and the scarcity is expensive, and the hungry marketing satisfies the appetite of those nobles and businessmen.

In the evening, Wang Yuan left Gu Yingxiang for dinner, and Jin Wei and Chang Lun suddenly came to visit with wine.

"Are you thieves together? Why are you crying with a sad face? Wang Yuan asked with a smile.

Chang Lun drank alcohol to himself, and said angrily: "Cabinet ministers, Zongzi committed murder, careless of human life, the three law divisions actually want to get by!" ”

Wang Yuan said: "Isn't this kind of thing normal? You've encountered it before. ”

Jin Wei sighed and said: "This time is different, nearly three hundred lives, if you say kill, you will kill it, and the three law divisions actually want to exonerate a few masterminds." ”

"Three hundred lives?" Gu Yingxiang was taken aback, "Which of the sons of important ministers committed a case that can actually make the three law divisions soft?" ”

Chang Lun smiled: "Who else can there be?" Liang Ge Lao, who is incorruptible, dares to give direct advice, and asks for the people's life. ”

Here's how it happened-

In Nanhai County, the hometown of Liang Chu, a wealthy man named Tan Guanhai was beheaded for his crimes, leaving more than 100 dumped fields, which were successively occupied by the wealthy Yang Duan. Although Tan Zhen, the son of the Tan family, was angry, as a family member of the criminal, he did not dare to forcibly take back the family land.

So, Tan Zhen simply didn't want Jiatian, and only wanted to take revenge on Yang Duan to relieve the hatred in his heart. He donated more than 100 of his family's encroached land to Liang Chu's eldest son Liang Ciyi, Dai Zhongpeng, the son of Shangshu (deceased) of Nanjing's Ministry of Industry, and local heroes Ouyang Yuan and Li Runcheng. That's it, when he donated his own land, he also sandwiched the land of his enemy Yang Duan.

Yang Duan originally occupied the Tan family's property, but the result was inexplicable, and his own property was dedicated to the powerful and powerful by Tan Zhentou. The Yang and Tan families formed a mortal enemy, and there were many armed fights, Dai Zhongpeng, Ouyang Yuan, Li Runcheng and others saw that the matter was getting bigger and bigger, and they wanted to destroy the Yang family once and for all.

At this time, Liang Ciji had already been promoted to the Guangdong Metropolitan Division, and was one of the three chief officials of Guangdong Province. When he learned of this extermination plan, instead of stopping it, he also took care of it and sent people to kill nearly 300 members of the Yang family in the middle of the night.

Only one woman hid in the pond and narrowly escaped, and later reported the case to the police.

The Criminal Division, the Criminal Department, the Governor, and the Metropolitan Procuratorate all intervened to jointly try the case, and the mastermind all confessed. Immediately, the case was thrown back to the capital and tried by the Dali Temple, the Metropolitan Procuratorate and the Criminal Department.

Lu Wan, who supervised military affairs last year and cleared up the anti-thieves, has been promoted to the imperial history of the right capital because of his merits. He is Yang Tinghe's confidant, belongs to the same group as Liang Chu, and actually serves as one of the presiding judges of the case.

The other presiding judge was Zhang Zilin, the secretary of the Criminal Department, who was the prefect of Henan Province and had the first political performance in the country. When he participated in politics in Shanxi, he opened a warehouse to release grain and save the people. As a governor in Hunan, he gave relief to 400,000 victims. After being promoted to the secretary of the criminal department, he took the emperor's relatives and relatives to open the knife, and was upright, and was later known as the "ancestor of a generation of criminal names". I don't know the real situation, anyway, the history books say so. Such an upright person actually wants to exonerate the mastermind of the iron case!

How did these two decide the case? When several of the principal offenders pleaded guilty, they said that they were only accomplices, and they also made a judgment that "the situation is heavy and the law is light, and it is difficult to deal with them regularly".

The Criminal Department and the Metropolitan Procuratorate wanted to fool things, but of course Dali Temple didn't do it.

The main responsibility of Dali Temple is to review all kinds of major cases, and if something goes wrong, you have to take the blame! Zhang Lun, the secretary of Dali Temple, was angry, and various trial results were denied, and the trial of the three law divisions could not be concluded.

Zhang Lun didn't go to the trial anymore, and in order to express his dissatisfaction, he only threw a few interns over to fool him. He wants to drag it all the time, make the case bigger, and make it so big that no one dares to cover it.

As a result, Jin Wei and Chang Lun, two interns of the Supreme Court, have personally experienced this major case in recent days, seeing the dark side of Ming officialdom thoroughly, and at the same time offending several bigwigs in the DPRK and China.

Historically, the careers of Jin Wei and Chang Lun are estimated to have been seriously affected because of this incident.

After listening to the two of them clenching their fists, Wang Yuan suddenly smiled and asked, "Zhang Jianqing (Dali Siqing Zhang Lun) asked you to come?" ”

"How do you know?" Jin Wei was very surprised.

Wang Yuan said: "My palace examination article, Zhang Jianqing is a circle, how can I repay one or two." ”

Chang Lun took out a note and said, "Zhang Jianqing has continued to go to His Majesty, and the recitals have been deducted by the celebrant and the cabinet. He doesn't mean anything else, he just wants to ask you to hand the piece to His Majesty. ”

Wang Yuan asked Jin Wei: "What does your future father-in-law (Jin Gui) say?" ”

Jin Wei replied: "Let me leave it alone, this matter is too involved, but Jiayue is also very dissatisfied with the Metropolitan Procuratorate and the Criminal Department. ”

The civil official group is really not monolithic, Yang Yiqing and Zhang Lun, who once drew a circle for Wang Yuandian's articles, have been in conflict with Yang Tinghe in the past few months. The former has resigned twice because of reform issues; The latter, who insisted on justice and was ready to resign, threatened to resign.

And Jin Wei's quasi-father-in-law, Jin Gui, is not from the same party as Yang Tinghe, strictly speaking, he belongs to the Imperial Party and Li Dongyang's Party.

Wang Yuan accepted the piece and said with a smile: "Tomorrow I am going to present the clairvoyant mirror to Your Majesty, and it doesn't matter if you hand over a piece of music, but you must not say it outside, otherwise I will be hated by some important ministers." ”

Jin Wei and Chang Lun swore at the same time: "If you leak any word, the sky will be struck by five thunders!" ”

Gu Yingxiang also felt that the matter was important, so he swore a poisonous oath.

Wang Yuan felt that he could add some materials to Uncle Wang and send the two students over, so he said, "Two virtuous brothers, do you know Mr. Yangming's mind?" ”

"I know a little bit about it." Jin Wei, Chang Lun Dao.

Wang Yuan said with a smile: "Another day, the teacher will give a lecture, why don't the two virtuous brothers listen to it?" ”

Chang Lun and Jin Wei didn't understand, but they couldn't excuse themselves, so they both nodded and said, "I'm willing to listen to the teachings." ”

With Uncle Wang's level, he should be able to fool them into apprenticeship.

Everyone plays in groups together, and in private they are centered on the mental circle, and the DPRK can temporarily make friends with Yang Yiqing and Zhang Lun.

One day Wang Yuan will be in power, Yang Yiqing will definitely be the vanguard of reform, and Zhang Lun's insistence on judicial fairness also makes Wang Yuan admire.
