Wang Tiqian didn't know if it was or not, but as soon as the emperor asked, he hurriedly responded: "Master Long, wait a minute, the slave will go and ask." With that, he walked quickly into the alley.

Zhu Youxiao stopped, looked at Li Chengcheng, and said, "If you want to hear about the book, you will find an opportunity in the future." ”

Li Chengcheng nodded, smiled and said, "The slave maid thinks it's average, Master Long doesn't have to worry about it." ”

"There should be some shows for the New Year." Zhu Youxiao said: "Even if it's just singing and dancing. ”

Li Chengcheng just wanted to tell the emperor that as long as he was willing, the Teaching Workshop Division was not always on hand. Seeing Wang Tiqian walking back quickly, he closed his mouth again.

"Master Long." Wang Tiqian rushed to the front and bowed down to report: "This is Lord Xu's mansion. ”

Zhu Youxiao pondered for a while, raised his hand and said, "Let's go, go and drink a bowl of tea, I really have something to tell Master Xu." ”

Wang Tiqian led in front, and Zhu Youxiao and the others entered the streets and alleys, and went straight to Xu Guangqi's mansion.

The mansion given to Xu Guangqi is not big, and it cannot be compared with the mansion compound of the powerful people in Beijing. But Xu Guangqi lived very comfortably, without too much noise and noise, and did not need to have too many nursing home bodyguards.

Moreover, Xu Guangqi was originally tolerant and loose, which may have something to do with the fact that he often spent time with Western missionaries.

When I came to the door, I saw that the door of the house was ajar, and I didn't know what the reason was. Moreover, there is not even a nursing home or gatekeeper in front of the door.

Could it be that entering the Xu Mansion is as casual as walking through the city gate? Zhu Youxiao was a little puzzled, but saw that Wang Tiqian had already walked in in front of him, so he had to follow.

"Hey, hey, what about when the city gate goes?" Wang Tiqian didn't expect someone behind the door, so he stopped when he heard the sound and turned his head to look.

A middle-aged man came over with a cigarette pouch and pot, rolled his eyes and asked, "Do you know, this is Xufu, although there are fewer people, don't be too casual!" ”

Without waiting for Wang Tiqian to speak, Zhu Youxiao had already preemptively said: "It's a drop, it's a drop, it's a mistake on our part." As he spoke, he beckoned to Lu Jianxing, who was hesitating to follow up.

Lu Jianxing hurried over, and heard the emperor instruct in a low voice: "Show off your waist card, just say that the emperor sent you to give a reward to Lord Xu." ”

Lu Jianxing bowed down and agreed, secretly praising Long Live for being thoughtful. Not to mention the award, as soon as you show your identity, you think you are here to arrest people and put them in prison!

With a dry cough, Lu Jianxing stepped forward, flashed the brocade clothes and guard's waist card, and said: "Lu Jianxing, the superintendent of the hundred households, came to present the reward by the Holy Command." ”

The middle-aged man looked fixedly, hurriedly bowed down, and said busily: "The little one will go and announce it, and invite the adults of my family to come and receive the order." ”

"No need." Zhu Youxiao waved his hand and said, "Long live the special explanation, don't be too public, you just lead us to see Lord Xu." ”

"The little one obeys." The middle-aged man hurriedly stretched out his hand to invite him, and walked a few steps to lead the way, and said as he walked: "My family is talking to Priest Tang, and it is about the stars and the moon. ”

Zhu Youxiao nodded, they are not outsiders, and they are probably discussing which cosmic system to refer to for the revision of the almanac. Although he specified Copernicus's heliocentric theory, it may not convince Xu Guangqi and Tang Ruowang.

Of course, this spirit of respecting science is commendable, and Zhu Youxiao is not angry and blamed for it.

As he spoke, the crowd was led into the hall. I didn't see a few people along the way, so you can see Xu Guangqi's personality and preferences.

For Xu Guangqi, the history books contain: on the day the coffin was covered, there was nothing left.

is so knowledgeable, so capable, and the official position is also secondary, but in the end, he is so poor. Those greedy people, I don't know what face, fancy clothes, food, high-rise mansions, and groups of wives and concubines?

"There's no need to report it, I know Master Xu well." Zhu Youxiao stretched out his hand to stop the subordinate who was leading the way, stepped up the steps, and went straight into the hall.

Xu Guangqi and John Tang were talking about how to make observation instruments in order to verify Copernicus's system.

You know, Copernicus was not a very good observer, and his accuracy may still be very poor.

Tycho, on the other hand, did an excellent job of instrumentation scales and errors, with minimal error between actual measurements and theoretical estimates.

Someone pushed the door in, Xu Guangqi and Tang Ruowang didn't care, and were still talking about astronomical things.

In fact, Xu Guangqi is not good at astronomy, and compiling almanacs is certainly his wish, but it only plays an organizational role in the calendar.

Therefore, he has great respect for the Western missionaries he has to rely on, such as John Tong, Deng Yuhan and others.

Seeing that Xu Guangqi and the Westerners were talking enthusiastically, and they actually ignored the Long Live Lord, Wang Tiqian couldn't help but cough dryly.

Zhu Youxiao couldn't help but glance at Wang Tiqian, he still wanted to hear Xu Guangqi and Tang Ruowang talk!

Xu Guangqi turned his head a little displeased, and when he saw the smiling emperor, he couldn't help but widen his eyes. After a little stunned, he hurriedly knelt down and saluted.

"Xu Qing is exempt!" Zhu Youxiao waved his hand, sat down in the chair honestly and unceremoniously, and smiled at Tang Ruowang, who was saluting, "The same is true for Priest Tang. The two of them sat down and spoke. ”

"Long live Long En of Wechen Xie." Xu Guangqi fell to the ground and sat down with Tang Ruowang, looking a little panicked.

Zhu Youxiao pondered for a moment and said: "First build the observation equipment, set up a few more observation points, and verify the Copernicus system." If there is solid evidence to support it, Xu Qing and Priest Tang can write this book, and they can leave their names in the world and be respected as pioneers. ”

John Tang arched his hand and said, "Your Majesty." This would be time-consuming and labor-intensive, but with the Tycho system, there is no such problem. ”

Zhu Youxiao shook his head and said, "Tycho is wrong, although now, his error is very small. Well, there is no need to argue or hesitate, just make observations according to Copernicus's system and compile an almanac. ”

John Tang smiled bitterly and stopped arguing.

Xu Guangqi thought for a while, arched his hand and said: "Long live must also know about the dispute between the West Bureau and the East Bureau, and Qin Tianjian also opposes the West Bureau. If the almanac is not accurate enough, it may not be convincing. ”

Zhu Youxiao bowed his head lightly, knowing that Xu Guangqi was under a lot of pressure to preside over the work of the bureau. The forces of the people who oppose the introduction of Western learning, that is, the so-called "Eastern Bureau"; Qin Tianjian advocates the traditional calendar and is also an opposition force.

After pondering for a while, Zhu Youxiao said: "Xu Qing doesn't have to pay attention to other matters, I will fully support the previous bureau." Learning Tycho's method of observation and applying it to the Copernican system, I believe it will be accurate. ”

Raising his hand and pressing down, Zhu Youxiao smiled: "I won't talk about this today." One is to sit casually, and the other is to chat casually. Let's talk about this new learning! ”

It used to be called the Academy of Sciences, but later it was renamed Xinxue, and it was much faster to recruit literate and hyphenation scribes to study, which was much faster than the training of orphans from an early age.
