My Daming New Empire

The Ma family has now become one of the most important suppliers of internal surveillance, producing telescope lenses and prisms for military equipment, and is currently developing plane mirrors and concave lenses, as well as microscopes.

With Zhu Zhanji's support, coupled with the great business of the Ma family, although the reputation is not as good as those of the old relatives, the family is not weak at all.

This kind of family background also made her not need to rely on others in the harem at all. When she was a little older and had one or two children, her position would be more stable.

The Ma family father and son entered the room under the leadership of Li Liang. Ma Zhide was wearing a scholar's robe and with a thin figure, he looked like an older wealthy idler.

Maddy is growing and growing taller and thinner.However, he was wearing the military uniform of the young army, which added a bit of heroism.

The two wanted to kneel down, but Zhu Zhanji stood up and stopped them. "Today is Xiner's birthday, no matter how high or low, it is only about affection. Did Auntie go to see Xiner?"

Although he was praised by Zhu Zhanji, Ma Zhide didn't dare to forget about it, and sat down humbly before saying: "Mrs. Liu Lin of the Suzhou government personally came to Beijing to celebrate Xiner's birthday, and Xiner is receiving them now..."

Seeing his difficult expression, Zhu Zhanji asked, "But do you have something to tell me?"

Ma Di couldn't hold back and said: "Your Highness, the people of Suzhou Mansion are too miserable..."

Ma Zhide growled, "Shut up..."

Maddy pouted, but didn't dare to interrupt.

Zhu Zhanji knew Ma Zhide's behavior well.Although he didn't let Ma Di speak, what he showed was that he wanted to speak for the people of Suzhou Prefecture.

But speaking of it, the people of Suzhou Mansion are indeed suffering, not ordinary suffering.

Because at the beginning of the founding of the People's Republic of China, Suzhou Prefecture, as Zhang Shicheng's "national capital", has persisted for 12 years.Even if Zhu Yuanzhang took over the world, the people of Suzhou Mansion still love Zhang Shicheng.

So after the founding of the Ming Dynasty, Suzhou Prefecture was the one that was punished the most.

In the early days of Hongwu, the tax of Suzhou Prefecture was several times higher than that of other places, and one-tenth of the tax of the entire Ming Dynasty was borne by one prefecture.

Although Suzhou Prefecture is rich in the world, such taxes also make the people miserable.

Such a high tax can only be collected in a good year, and it will be impossible to complete it in a bad year.

So whether you go to Suzhou Prefecture to be a magistrate or a county guard, the main task is to exploit the people.

During the Hongwu Dynasty, 28 magistrates and 32 county magistrates of Suzhou Prefecture were replaced, an average of one change per year. It can be said that there is no place in the world where officials change so frequently.

Although Suzhou Mansion is rich in the world and it is the best mansion in the world, but no official regards going to Suzhou as a beautiful errand.

It was not until the Yongle period that Zhu Di gradually reduced Suzhou's taxes.But now, the tax amount of Suzhou Prefecture still accounts for [-]% of Daming's land tax, and the amount owed in previous years has not been cancelled.

Zhu Zhanji pondered for a while and said: "I have not yet been in charge of the government. This is civil affairs. It stands to reason that I am not qualified to intervene. But this year, Ming Dynasty has ample financial resources. I will persuade the emperor's grandfather when I have the opportunity."

"Your Highness is benevolent and righteous. As a native of Suzhou, I am grateful to His Highness for the people!" Ma Zhide fell to the ground and said emotionally: "The Zhang family was originally from Jiangsu and Zhejiang. When they fought against Taizu for the world, the local people naturally supported him. But Taizu After ascending to the throne, Suzhou has also been punished for more than 50 years. The richest man in the world is now living in dire straits..."

Zhu Zhanji smiled and said: "It's not that the people are living in dire straits. Although the people are suffering, the business in Suzhou Prefecture is developing well. Since Liu Lin took office, a Nupuji Hall, a Hui'an Hall, and a Yuying Hall have been built in Suzhou Prefecture. One, one Jishan Hall, and one Sangjing Hall, all of which were built with donations of more than [-] yuan from merchants."

Ma Zhide obviously didn't know that Zhu Zhanji had such a clear understanding of Suzhou, and he didn't know how to react for a while, so he could only say: "Master Liu Lin still...has done some practical things."

Zhu Zhanji nodded and said: "I know about this, but don't get involved too much, I know it well. Can concave lenses and prisms be mass-produced?"

Compared with convex lenses, the production of concave lenses is more troublesome, and it is also more difficult to produce qualified products.

The convex lens can form a corresponding molten mold by solidification of the glass solution, and can be shaped after simple grinding.

But the concave lens must make a corresponding ring mold to allow the solution to stretch.In the case of non-standard mold dissolution, polishing depends entirely on the experience of the master, so the production is more difficult.

As for the triangular prism, although it is triangular, all three sides are flat. As long as there is a mold, it is easier to polish.

With the advancement of technology, especially the application of prisms, the multiples of telescopes can now reach higher.

Just before Zhu Zhanji returned triumphantly, Si Tianjian built a viewing platform on Zijin Mountain at the northern foot of Zhongshan Mountain, and used a telescope with a power of more than [-] times to observe the starry sky.

The basic principle of the microscope and the telescope is actually the same, they both want to enlarge the object, but the research directions of the two are not the same, one is to shorten the distance, and the other is to enlarge the object infinitely.

The simplest distinction is that a microscope is a compound telescope.

Zhu Zhanji only knew about these superficial concepts, but did not understand the specific principles. However, with his guidance, Ma Zhide has already created a fixed microscope that can magnify about [-] times.

This kind of microscope can clearly see the bacteria on the human body. Now, Xiamaqiao Medical Research Institute and Taiyuan Hospital often fight for the right to use the microscope.

However, because the lens is difficult to polish, the second microscope has not yet been produced.

After inquiring about the production progress of the microscope, Zhu Zhanji said: "Whether it is a microscope or a telescope, in addition to making it, it is necessary to establish standards for production and use. I hope Deon will pay more attention to this. "

Although he can be regarded as Zhu Zhanji's old father-in-law, it is impossible for Zhu Zhanji to call him father-in-law. De Weng is already an honorary title.

Ma Zhide agreed, and Zhu Zhanji said again: "Since Mrs. Liu Lin has also come to the other courtyard, we will stay for dinner tonight, stay overnight, and return to Beijing with me tomorrow."

Ma Zhide understood that it was Zhu Zhanji who gave him face.Otherwise, it would be impossible for the wife of a fourth-rank magistrate to have dinner with Zhu Zhanji, let alone stay in his royal courtyard.

And in this way, it also represented Zhu Zhanji's praise of Liu Lin, which would make him, the prefect of Suzhou who only took office this year, much less stressed.

You must know that when he took office, Dong Xi, the former magistrate of Laizhou, wanted to collect tax arrears by tough means because there was no support in the court, which caused public outrage. He was demoted to Yunnan just a year after he took office.

Zhu Zhanji didn't know much about Liu Lin, and what he knew was only some information on the information. He was born in a poor family in Raozhou, and he was cautious as an official.

When he served as the inspector of the Metropolitan Procuratorate in Sichuan, he actually did a few practical things, and then he made his way to the sky and became the prefect of Suzhou.

However, in Zhu Zhanji's heart, an official who can do practical things and is willing to do things for the people is a good official.So the old man came forward today, and he didn't mind supporting him indirectly so that he wouldn't feel so stressed.

Mrs. Liu Lin is a woman in her forties, not like the magistrate's wife, but like an ordinary woman.The two little maids she brought were also plain and simple. They trembled when they saw Zhu Zhanji, and they didn't have any grandeur.

Treating them to a dinner, Zhu Zhanji took Ma Di out and ordered Li Liang to send someone to Jinyiwei to get a copy of Liu Lin's detailed information.

If this person is really an upright and capable official, he thinks he will pay attention to it.He doesn't mind killing chickens and scaring monkeys if he does one thing in front of his face and one thing behind his back.

Although he can't intervene in civil affairs now, it is still easy to deal with a magistrate.

What he hates most is being deceived.

Ma Di is now not only a mathematics teacher of Youjun, but also a student of Youjun. Of course, what Zhu Zhanji values ​​most about him is his ability in scientific research.

Because he is proficient in mathematics, after turning his energy to hang gliding, he now devotes all his energy to the study of mechanics.

Mechanics can be seen everywhere in life and is widely used, but in this era, people who are deeply influenced by Confucianism know what it is and don't know why, and no one studies it systematically.

The task Zhu Zhanji assigned to Ma Di was to analyze every bit of "normality" in life with mathematics.

For example, the formation of wind, why leaves fall, why water flows down, why bearings save effort, the principle of levers, and why hang glider can fly.

These matters seem simple, but to explain them clearly involves extensive theoretical research and experiments, so Madi is now busy with nothing else.

Zhu Zhanji also knew that letting him, a 19-year-old kid, study this would be a bit of abuse to him, but now only young people whose ideas have not yet been finalized are willing to study these things.

If he can explain these theories clearly, then the most complete basic physics can be formed, which will be a leap for mankind.
