Since the Chenghua period, people have successively suggested revising the calendar, but the proposers were either punished or rejected on the grounds that "the ancient law cannot be easily changed" and "the ancestral system cannot be altered."

In November of the 38th year of the Wanli reign, the Imperial Astronomical Observatory again made an incorrect prediction for a solar eclipse. The court then decided to have Xu Guangqi and missionaries translate Western calendars for reference when revising the calendar, but the plan was soon abandoned.

The court let the matter go, but Xu Guangqi was still thinking about it.

Now, the work of the weapons and gunpowder bureau had been taken over by his disciples and other capable people, so he submitted a petition to open a calendar bureau and revise the calendar.

Zhu Youxiao didn't take ancestral rules and ancient methods seriously. Since the calendar was inaccurate, he just revised it!

Zhu Youxiao approved Xu Guangqi's proposal. After a long pause, the young emperor wrote a longer instruction, or explanation, to Xu Guangqi.

Ginni brought a lot of books. In addition to the dozen or so books designated by Zhu Youxiao, Xu Guangqi and the missionaries also planned to translate some others.

Among them is the theory of Danish astronomer Tycho Brahe.

It is undeniable that Tycho's observations were of a precision far beyond the reach of his contemporaries, and the star catalog he compiled was quite accurate and remains valuable to later generations.

But his view of the universe was wrong, he believed that all planets revolve around the sun, and the sun led the planets to revolve around the earth. This system was introduced to China in the early 17th century and was once accepted.

Although Copernicus published "On the Revolutions of the Celestial Spheres", the heliocentric theory did not establish absolute authority at the time and was highly controversial.

Therefore, the historical "Chongzhen Calendar" believed that the Tycho system was correct. Astronomical tables were compiled based on the Tycho system and also cited a large amount of Tycho's observation data.

Zhu Youxiao issued this instruction because he felt that since it would take manpower, money, and time to compile a calendar, he should try to make it the best and most scientific one possible. Otherwise, wouldn't it be considered a waste?

Don’t think that Zhu Youxiao is meddling in other people’s business. In feudal society, studying astronomy and calendars was a taboo for the rulers.

At the beginning of the Ming Dynasty, there was a rule that "the study of astronomy and the calendar was forbidden. Those who studied the calendar were exiled, and those who created the calendar were put to death." Pointing at the stars and talking nonsense would result in beheading.

What about observing the celestial phenomena at night? That is not something that ordinary people can or dare to do. It is the specialty of the Imperial Astronomical Observatory established by the imperial court.

Xu Guangqi's plan to revise the calendar based mainly on Western astronomical theories would certainly be opposed by the Imperial Astronomical Observatory and the forces in society that opposed Western learning.

Therefore, Zhu Youxiao's attitude is crucial.

The emperor said that China was the center of the world, so the map of the world presented by the foreigners was quickly modified to put the Ming Dynasty in the center;

The emperor also said that no matter what the Ziwei star is, the round sky and square earth are the truth, so how could others dare to argue with it?

Zhu Youxiao finished writing his reply to Xu Guangqi and would also support him in "Daming Forum" and the official newspaper. Then he put down his pen and stretched.

With a quick glance, Zhu Youxiao discovered that Xiaobai had jumped onto the small table at some point and was staring at Li Chengcheng.

Alas, the owner has a baby and can’t play with you anymore!

Zhu Youxiao guessed that Xiaobai had seen it wrong and thought that the owner had returned, so he ran over to be intimate with him. Now he probably saw clearly that it was not the owner.

Li Chengcheng stared at the white cat, watching it jump up enthusiastically, then its strange eyes flashed with a look of confusion, and then it drooped its big head in disappointment. Feeling how pitiful it was, he bravely reached out and touched it.

Xiaobai let out a "meow" sound, and his already dim eyes became bright again, and his big head was raised.

Then touch it again. Li Chengcheng pursed his lips and smiled slightly, and he liked it very much in his heart.

Xiaobai did not dodge, but instead stretched out his little tongue and licked Li Chengcheng's hand.

Zhu Youxiao didn't say anything, just watched quietly.

It is normal for cats to have feelings for their owners, but Xiaobai was really disappointed without the familiar Zhang Yuer, and he seemed depressed these days.

Zhu Youxiao also arranged for a palace maid to serve Xiaobai, but Xiaobai didn't like it and would rather stay on the cat tree most of the time.

Whether humans and animals can be intimate with each other and stay together for a long time is also a kind of fate, or induction, just like the way people get along with each other.

Zhu Youxiao understood Xiaobai's loneliness and loss very well, so he didn't want to disturb the interaction between Xiaobai and Li Chengcheng, so he took the question book and started reading it.

Relatively speaking, Zhu Youxiao usually read the memorials or petitions from military generals and several trusted ministers himself.

The reason was simple: it was easier to understand and didn't require much thought. Military commanders generally had limited education, so straightforward language was easier to understand. Trusted ministers, knowing the young emperor's temperament, deliberately did so.

The memorial now in the hands of the young emperor was submitted by Mr. Yuan, the governor of Denglai.

Xu Hongru's rebellion was suppressed, and the recruitment of soldiers in Jianghuai was completed. Yuan Keli received strong support from the court and could finally concentrate on the training and strengthening of Dengzhen.

Yuan Keli's memorial was to outline this year's battle strategy and to warn the young emperor not to be impatient. Of course, Yuan Keli didn't know that although the emperor was young, he was as steady as a rock.

According to Yuan Keli's strategic deployment, 50,000 elite naval and land troops will be trained and 1,000 warships will be built.

Of course, all this requires money, which is what the question requires, to allocate enough funds to "repair warships, prepare equipment, replace the island commanders, and sail thousands of ships to follow their lead."

Yuan Keli remained cautious about the ongoing harassment campaign, prioritizing training and testing the actual combat effectiveness of the newly restructured army.
