"Xu Guangqi, a grass citizen, greets Your Majesty and wishes Your Majesty Jin'an."

Xu Guangqi, who is 65 years old this year, is radiant and energetic at the moment, and his eyes are bright.

Xu Guangqi, whose name is first, is still a Catholic, the holy name Paul, Han nationality, a native of Fahuahui (now Shanghai) in Shanghai County, and a famous scientist and politician in the Ming Dynasty. The official is the secretary of the Ministry of Rites of the Chongzhen Dynasty and the scholar of Wenyuan Pavilion.

Xu Guangqi devoted his life to the study of mathematics, astronomy, calendar, water conservancy, etc., and wrote diligently, especially proficient in agriculture, and translated books such as "Geometric Originals", "Taixi Water Law", and "The Complete Book of Agricultural Administration". At the same time, he is also a pioneer in the communication between Chinese and Western cultures, and can be said to be the first person to open his eyes to the world.

In the 34th year of Wanli, he began to cooperate with Matteo Ricci in translating the first six volumes of the Geometric Originals, which were completed and engraved and published in the spring of the following year. After translating the Geometric Originals, he translated the book The Law of Measurement based on Matteo Ricci's dictation.

In the thirty-eighth year of Wanli, Xu Guangqi returned to Beijing and was reinstated. Because the Qin Tianjian was inaccurate in calculating the eclipse, he cooperated with the missionaries in the study of astronomical instruments, and wrote the "Jian Pingyi Theory", "Pinghun Diagram Theory", "Sundial Diagram Theory" and "Night Dial Diagram Theory".

In the 40th year of Wanli, he learned Western water conservancy from the Jesuit priest Xiong Sanba, and co-translated 6 volumes of "Taixi Water Law".

In the forty-sixth year of Wanli, after Jin Nurha's red troops invaded the pass, Xu Guangqi was called to enter Beijing at night.

In the forty-seventh year of Wanli, the Ming army was defeated in the battle of Salhu, and he repeatedly asked for military training, and was later promoted to Shao Zhan Shi and Henan Provincial Imperial History, supervising the training of the new army in Tongzhou. However, due to difficulties in the supply of military salaries and equipment, the training plan did not go smoothly.

In the first year of tomorrow's Qi, Xu Guangqi returned to Tianjin in March to recuperate, and in June Liaoyang fell, he was called back to Beijing again, and asked to use Hongyi artillery to help defend the city, but due to disagreement with the military department, he resigned again in December.

In the fourth year of the Apocalypse, Xu Guangqi was promoted to the right attendant of the Ministry of Rites and the post of bachelor, but at that time, Wei Zhongxian was in power, and he refused to take office, and he was impeached and removed from office the following year.

Xu Guangqi paid special attention to the manufacture of weapons, especially artillery. Tubular firearms were originally invented and created in China, but by the end of the Ming Dynasty, the technology of manufacturing firearms had gradually fallen behind, and due to the needs of border defense, it was urgent to introduce artillery manufacturing technology. For this reason, Xu Guangqi has made many suggestions and continued to sparse. Xu Guangqi also explored the use of firearms in practice, firearms and urban defense, firearms and siege, and the coordination between firearms and infantry and cavalry. Xu Guangqi can be called the first person in the history of Chinese military technology to put forward the theory of the application of artillery in warfare.

These are some of the deeds about Xu Guangqi that Zhu Youxiao thought of in his mind, for this person who can not only build artillery, but also lead troops to fight, and can also theorize, it can be said that God arranged it for him, if he doesn't make good use of it, it will definitely be the biggest waste.

"Lord Xu is exempt, I don't know if Lord Xu has been happy recently, otherwise why is he so interested."

Zhu Youxiao is still very fond of Xu Guangqi's current performance, after all, if he is really old, weak, sick and disabled, he will not be able to do the work he arranged at all, and it is very likely that his first move will not be able to continue.

"Naturally, the grass people are radiant because they are honored to see His Majesty. In addition, several books written by the grass people some time ago have been officially published."

Xu Guangqi completely ignored the face of sixty or seventy-year-old people, and directly slapped Zhu Youxiao nakedly.

Zhu Youxiao couldn't help but feel a little interested when he heard Xu Guangqi say that he had a few books published. After all, this is a great scientist in the late Ming Dynasty, and his published book must be about science or something.

"Lord Xu, I don't know if I will be lucky enough to watch it."

Zhu Youxiao sat on the dragon chair and looked at Xu Guangqi standing in front of him expectantly.

Xu Guangqi saw that Zhu Youxiao was looking forward to his work so much, and his pride suddenly arose.

"The grass people have brought a few copies for His Majesty to preview." As he spoke, Xu Guangqi took out a few thread-bound books from his sleeves and handed them to Zhu Youxiao, who was sitting on the dragon chair.

Waiting for the little eunuch on the side, he hurriedly stepped forward to add a few books, and after carefully inspecting them, he handed them to Zhu Youxiao.

Zhu Youxiao saw the book handed over by the little eunuch, and there was a burst of ink on the brand-new writing.

Zhu Youxiao instructed the little eunuch who was waiting on the side to bring Xu Guangqi a chair, and he was concentrating on reading the book handed over by Xu Guangqi.

The three books written by Xu Guangqi correspond to agriculture, calendar, and water conservancy, and some of the records are also eye-opening to Zhu Youxiao, and he attaches more importance to Xu Guangqi's identification.

"Master Xu, did you ever know why I recruited you to Beijing?"

After roughly doubling the three books, Zhu Youxiao wrote a book and asked Xu Guangqi who was sitting on the side softly.

"The grass people don't know".

Xu Guangqi looked at Zhu Youxiao with a puzzled expression, about why Zhu Youxiao recruited himself into Beijing, Xu Guangqi really didn't think of why?

Although he is the right Shilang of the Ministry of Rites, he does not have a close relationship with his colleagues in the DPRK and China, and after he goes back, he focuses on writing books and does not care about some things in the court.

"I am recruited by my family this time, in fact, I want to establish a Ming Royal Academy of Sciences, I hope you can come here to be the dean", Zhu Youxiao saw Xu Guangqi's puzzled face, and directly picked it out.

"Your Majesty, what does this Ming Royal Academy of Sciences do? And what is this dean"?

Xu Guangqi searched for a long time, but still didn't understand what Zhu Youxiao meant, so he had to ask Zhu Youxiao.

Zhu Youxiao couldn't help but make a few words to himself in his heart, "I am also a quick mouth, how can such a thing as the Academy of Sciences have this word in the Ming Dynasty?" And the dean".

"The Daimyo Royal Academy of Sciences is equivalent to the Imperial Prison of the Kingdom, and as for the dean, it is the sacrificial wine."

"What this Guozijian teaches is not the words of Confucius and Mencius, the way of the sage. Most of them are some Western astronomical and geographical disciplines, and Lord Xu knows a lot about this, so he recruited you to Beijing to be able to serve as the dean."

"It's just that this dean is not an official position, I hope Lord Xu doesn't mind."

Xu Guangqi himself disdains the intrigue in officialdom, and because he is already old, he has no intention of returning to officialdom again. I thought about cultivating books at home and talking about this life, but when I heard Zhu Youxiao's suggestion at this moment, I couldn't help but feel my heart pounding.

"I don't know where Your Majesty, the Ming Royal Academy of Sciences, is now, the grass people want to go and see it now."

After Zhu Youxiao heard Xu Guangqi's words, he couldn't help but smile embarrassedly.

"What is that Xu Aiqing, this Ming Royal Academy of Sciences has not yet been built."

Xu Guangqi was like a fire that had been poured with a basin of cold water, and it died down in an instant. looked at Zhu Youxiao dumbfounded, and muttered in his heart.

"You recruited me from my hometown to the capital from all afar, and it was so lively. The old man couldn't stop wanting to make some contributions to this society, but you told me that the college had not yet been built. Do you think that if you are the emperor, you can do whatever you want".

If Xu Guangqi had stayed in the afterlife, he would definitely have a fragrant mouth in his heart.

"I'm taking off my pants, and you told me you're here for your aunt."

"That Lord Xu, although it has not been built now, I have already arranged for people to prepare to build it. And this time, I didn't recruit Lord Xu to take office immediately, but I hope that Lord Xu can find more people like you, after all, you can't be the only one in the entire Academy of Sciences."

Xu Guangqi looked at Zhu Youxiao and nodded, indicating that he had understood.

"Companion, did you understand what I said to Master Xu?"

Zhu Youxiao turned around and looked at Wei Zhongxian, who looked like a wooden Zhuangzi.

"The old slave has already understood, there is a good place in Xishan, which is sparsely populated and suitable for the Academy of Sciences that His Majesty said."

Zhu Youxiao thought about it, nodded and agreed with Wei Zhongxian's suggestion.

"I will take 100,000 taels of silver from my inner money and hand it over to Lord Xu, as for the Royal Academy of Sciences, it will be presided over by you and Lord Xu, remember that Lord Xu is the main one."

"Lord Xu hopes that he and his companion can put aside their previous suspicions and work together to contribute to this Ming Royal Academy of Sciences."

Zhu Youxiao looked at Xu Guangqi apologetically, and at the same time gave the two of them a warning, don't tear each other down in this matter, after all, the two have some relationship.

"Old slave, grass people's respect".
