After Chu Yun and others returned to the capital, it caused a stir. Chu Yun had been away from here for more than half a year. At the same time, when he returned in triumphant, his reputation reached another peak with his achievements in conquering Nanyang!

In addition, after Chu Yun announced the news that Ella was pregnant, his residence in the capital was crowded with people, and officials from various departments and military officials came to congratulate him, almost breaking through the lintel. The people in the city also celebrated these two things at the same time, showing a prosperous scene. In the face of incomparable prestige, no one would doubt Chu Yun's words, and he could easily build factories and railways without being opposed by the people.

Among these visitors were officials of the Ministry of Rites and the Ministry of Works. Chu Yun took advantage of their visit to ask about the progress of various departments and what happened. For example, during the period when Chu Yun left the capital, a major event occurred in the Ministry of Rites among the six ministries, which caused a sensation among the Ministry of Rites.

"Mr. Xu Guangqi has never survived this winter and has passed away at the beginning of the year. God will bless him." A blond and blue-eyed official said to Chu Yun.

This official was not summoned by Chu Yun, but a missionary who came to the Ming Dynasty in the late Ming Dynasty. He had a well-known name, Johnson Tang, who was recommended by Xu Guangqi, the Minister of Rites, and worked in the Imperial Heaven Supervision in the capital three years ago.

Later, Chu Yun re-changed the Six Ministry, and Xu Guangqi and Tang Ruowang still took office in the Six Ministry. Among them, Xu Guangqi was the Minister of Rites, and his departure had a great impact on the Ministry of Rites. Many officials of the Ministry of Rites had a relationship with Xu Guangqi. For example, Tang Ruowang had a close relationship with Xu Guangqi.

"It's rare to be seventy years old, and Mr. Xu Guangqi is seventy years old, and he has already been able to die with a good end. Unfortunately, he has not been able to bid farewell to him for the last time, which is a pity." Chu Yun said sincerely.

Xu Guangqi's status in the late Ming Dynasty was no less than that in the late Qing Dynasty Lin Zexu. He was a group of people who advocated the open eyes of the world, and was also scientists who were regarded as evil by traditional scholars. His achievements in agriculture, astronomy, and mathematics were particularly significant. The last lunar change in the world where Chu Yun was previously located was from the "Chongzhen Calendar" compiled by Xu Guangqi, Johnson Tang and others. It can be said that it has influenced the most extensive peasant class in China for hundreds of years. In it, it has abandoned the concept of a round sky and a place, regarded the earth as a sphere, and introduced longitude and latitude... and also translated Euclid's "Origin of Geometry" with Matteo Ricci. The word "geometry" came from this and became a nightmare for many people later.

Of course, Chu Yun still relied on such an official, but unfortunately, when he began to pay attention to industrial science, Xu Guangqi died.

"Mr. Xu Guangqi said before his death that the atmosphere of science has improved, which is very comforting." said John Tsang.

"Have the new calendar not been completed yet?" Chu Yun asked about the lunar calendar reform.

The calendar of the Ming Dynasty was inherited from the Yuan Dynasty, and the Yuan Dynasty was inherited from the previous dynasty. It was no longer applicable in the late Ming Dynasty. According to records of Ming Dynasty history, after Xu Guangqi, Tang Ruowang and others compiled the "Chongzhen Calendar", it caused debate because of the issues of the new calendar and the old calendar. One debate took ten years. Finally, based on the records of celestial movements, Chongzhen found that the new calendar of Xu Guangqi and others was more accurate. When they were about to use the new calendar, the Qing people had already entered the pass. At present, Chu Yun is also urging the Ministry of Rites to draw out the lunar calendar he knew before.

"It will be completed approximately next year," said another official from the Ministry of Rites.

Chu Yun looked at the old official, who was a calendarist and mathematician Li Tianjing, who was more than fifty years old.

"The new calendar plays a significant role in planting arrangements and farmers understanding the climate. You, Johnson Chan and others, have to fulfill Xu Guangqi's last wish and formulate the new calendar." Chu Yun said.

"Yes, I don't know if Jun shouldn't give the new calendar a name?" Li Tianjing asked.

"It's called "Lunar Lunar New Year", which is a calendar specially formulated for agricultural production." Chu Yun thought about it and found that there was no more suitable name than the lunar calendar. It was simple and crude, but that's it. After all, ancient astronomical research was studied, in the East, it was mainly for agriculture and fortune-telling.

"This name is indeed very suitable." Li Tianjing, Tang Ruowang and others agreed.

"Why are the people who come to the Ministry of Rites still interspersed with officials from the Ministry of Works? If I remember correctly, your name should be Song Yingxing." Chu Yun looked at the newcomer from the Ministry of Works, an official named Song Yingxing.

"It's the Xiaguan! The Xiaguan happened to meet a colleague from the Ministry of Rites and arrived together." Although the man was in his forties, he couldn't help but say excitedly when he saw Chu Yun still remembering his name.

"The Xiaguan was originally just a failed person in Jiangxi Province. Later, the Ministry of Works recruited people who were good at 'mathematics', 'crafts', 'agriculture', and 'water conservancy', so they were selected. Later, the military leader, you suddenly had to be responsible for compiling industrial encyclopedias, recording the craftsmanship and technology of the past, present and future." Song Yingxing said.

Chu Yun's orders were naturally clear. When he saw the name Song Yingxing before, he had the idea of ​​asking him to compile an industrial encyclopedia, listing and organizing all the processes and technologies he already has.

Of course, these books cannot be published in the public, but are protected by the military. Song Yingxing has no right to touch on some core technologies involving security, and Chu Yun is secretly archived.

"How is the encyclopedia editing now?" Chu Yun was a little interested in this matter.

"But just started, new learning and skills are as complicated as a sea of ​​smoke and thousands of threads. It may take a lifetime to browse it." Song Yingxing sighed.

When Chu Yun heard Song Yingxing say this, he thought to himself that he would start new technologies from time to time. Now the technologies of the first industrial revolution and the second industrial revolution are mixed together, which is completely different from the machinery in the handicraft era. Without extremely outstanding talents, he would not be able to understand so many technical principles.

"The industrial encyclopedia does not need to be too detailed. It only needs to record its name, basic principles, and purpose. After the subject is determined, it will be much easier to hand it over to various departments of the Academy of Sciences to work together to improve it?" Chu Yun suggested.

"The lower official is stupid and didn't even think of this." Song Yingxing patted his head and woke up.

Chu Yun smiled slightly. The technologies of the two industrial revolutions were piled up together, and I am afraid that there is no "encyclopedia" character in this world who can understand all the technologies. It would be too exaggerated if Song Yingxing thought that it would be done by himself.

"If you can write a book in the future, the subordinates will come to the military commander to ask for a title." Song Yingxing saw that Chu Yun was willing to ask various departments of the Academy of Sciences to help him later, and was full of confidence in writing a book that was famous in history.

"I have already thought about it, it's called "The Art of Heaven and the Art of Creation". Chu Yun still felt that this name is much higher than that of an encyclopedia. 1
