golden scales

It was the twelfth lunar month of winter, and Zhu Cihong took the general staff from Jinan to Hanoi County where the Huaiqing government was located.

Huaiqing Mansion is located in the south of Taihang Mountain, in the area of ​​Jiyuan, Qinyang and Jiaozuo in Zhu Cihong's previous life.Because of its insufficient economic equivalent, Zhu Cihong didn't even have the slightest impression of these places in his previous life.This life came to Huaiqing Mansion in person, only then did I know that this place is actually a prosperous place in the Central Plains, with a deeper cultural heritage than Jifu.

Huaiqing Mansion is the fiefdom of Zheng Fan.Zheng Guo originated from Zhu Zhanyu, the second son of Renzong's concubine, who was first sealed in Fengxiang Mansion, and moved to Huaiqing in the ninth year of Zhengtong.This clan sealed fifteen prefectures successively, which can be regarded as a big clan.

It was also the lineage of King Zheng that allowed Zhu Cihong to eliminate his prejudice against his relatives.

Once upon a time, Zhu Cihong also felt that those mean people in later generations had a point: the suzerain vassals in the Ming Dynasty were like raising pigs.

Throughout the Chongzhen Dynasty, the last vassal kings such as Fu, Zhou, Qin, and Jin did play very disgraceful roles, and even insulted the name "pig".

However, it is a bit too much to completely regard the entire Ming clan as a "pig".Leaving aside the contributions made by the various clans to the continuation of Chinese civilization in terms of book collection, only the "Materia Medica for Relief of Famine" compiled by Zhou Wang Zhu Wei is still playing a role today. countless.

"Duanjing Shizi is not only an outstanding figure in my Zhu Ming Dynasty, but even if his achievements are placed among the 2000-year-old princes in China, he can still be ranked among the top three." Zhu Cihong walked slowly in Zheng Wang's mansion, followed by a A middle-aged man in his forties. ,

Judging from the color of the man's clothes, he is the king of the county.However, judging from the color of his face, it seemed that he had just suffered a great deal, and finally got rid of the danger of starving to death.

This person is the grandson of Zhu Zaiyu, the son of Duanjing, Zhu Changjie, the king of Dongyuan.

"Your Highness..." Zhu Changjie's voice choked up, her eyes were flushed, expressing her gratitude to the Crown Prince for his respect for his grandfather.

"As the grandson of Prince Duanjing, how do you compare to your elder father in law, calendar and arithmetic?" Zhu Cihong asked with a smile.

"I am ashamed!" King Dongyuan quickly bowed and said: "Although I have been taught strictly by my family since I was a child, I have learned "Music Rhythm" and "Suanjing", but my qualifications are stupid. , I dare not compare with my ancestors."

"Don't be humble." Zhu Cihong said: "If Prince Duanjing knows that his descendants can beat him, he must be very happy."

"I'm not underestimating myself," Zhu Changjie said calmly, "it's just my grandfather's talent, and he is not born in the world. I'm afraid no one can match it in the past hundred years."

Zhu Cihong nodded and smiled, thinking it made sense.

Sometimes diligence can narrow the gap between people, but after a certain level, there is an insurmountable moat between mortals and geniuses.Just like Zhu Zaiyu, it is no longer possible to get closer through hard work.

As a liberal arts student 400 years later, Zhu Cihong has always felt that his comprehension is not bad, and he has spent time studying several classic works of Zhu Zaiyu. It can be said that he can understand them with the help of Donggong lecturer But there was nothing he could do to push him forward.

Joseph Needham, the author of "History of Science and Technology in China", compared Zhu Zaiyu with Li Shizhen, Song Yingxing, Xu Guangqi, and Xu Xiake, which is by no means an exaggeration.

In the eyes of Zhu Cihong's two generations, Zhu Zaiyu is even greater than these four science promoters.

He is a scientific pioneer.

In mathematics, Zhu Zaiyu pioneered the use of abacus calculations for square extraction, and developed the sequence equation. He was the first in the world to solve the first term, the last term and the number of terms of the known geometric sequence, and solved the conversion of decimals in different base systems. , some of the calculation methods have been used until 400 years later, laying the foundation for the birth and development of physics and chemistry.

In terms of metrology, Zhu Zaiyu has conducted extremely detailed investigations and physical experiments on the determination of millet rulers, the relationship between ancient currency and weights and measures.In particular, the research on the change of the weight and measure system in the past dynasties has been affecting later generations.He proposed a series of calculation methods and calculation formulas for nozzle correction, and also accurately determined the mercury density.

In terms of astronomical calendar, Zhu Zaiyu believed that the calculation of the length of each year by the calendar at that time was not very accurate. After careful observation and calculation, he worked out the formula for calculating the length of the regression year.In 17 AD, astronomers used modern high-tech measurement methods to verify Zhu Zaiyu's calculation results in 21 and [-].The verification found that the length value calculated by Zhu Zaiyu in [-] was only [-] seconds away from the result calculated today, and the difference in [-] was [-] seconds.

He was also the first person in Chinese history to accurately calculate the geographical location of Yanjing.

As for the twelve equal temperaments he created were brought back to the West by missionaries, so he helped Bach invent the piano, and even became the standard tuning for later generations... Compared with Zhu Zaiyu's achievements in astronomy and mathematics, it is not particularly outstanding.Moreover, he invented the "Tianxia Taiping Dance" which was the first of its kind; the dance education syllabus and music education system formulated by him have been used by later generations to the foreseeable future...these are just the end of his contribution to human civilization.

……

"The state of Jiashen has changed, and the whereabouts of King Zheng are unknown." Zhu Cihong stopped, looked around the deserted courtyard, and said, "I have the heart to tell the emperor, and I want you to succeed King Zheng, are you willing?"

Zhu Changjie was taken aback for a moment, then knelt down on the ground, her throat rolled, and she was speechless for a while.He knew that the Crown Prince had summoned him because of Prince Duanjing's face, but he never thought that he would have the idea of ​​attacking King Zheng.Yifan Fengwang is the real nobleman of Tianhuang, the family of the emperor, while the county king can only be regarded as a distant relative and regarded as a courtier.In a patriarchal society, these are two distinct classes.

"Your Highness's love is hard to repay through generations!" Zhu Changjie said: "It's just that Your Highness, Zheng Wangjue is the patriarch Qi Shu, the master of the temple issued an order to praise him, and ordered his ministers to inherit the Dongyuan country. How dare I violate my ancestors? Human heart?"

There is quite a family story between the Zheng royal family and the imperial family.

Zhu Zaiyu's grandfather, Zhu Youwang, originally inherited the title of King Dongyuan, and later succeeded Wangfan Zheng.His father, Zhu Houtan, succeeded him as King Zheng in the sixth year of Jiajing. He was famous for his frugality, integrity and erudition. In the 29th year, Zhu Houtan went to the public, admonishing Emperor Jiajing to cultivate the truth and harm the country. Emperor Jiajing was furious and imprisoned the envoy of Zheng Guo.

It was at this time that Zhu Youfan, a commoner in Mengjin, took the opportunity to go to Emperor Jiajing to impeach Zhu Houfan for forty major crimes. He was charged with the crime of treason as the first, almost to put him to death.

The rebellion of the vassal kings in the Ming Dynasty was not without precedent, but it was not so turbulent, and the wind was like rain.Therefore, Emperor Jiajing went to the state of Zheng to hear the case as a son-in-law and a middle-ranking official.His replay to King Zheng was not guilty of treason, but there were such acts of usurpation as "ruling the name of the palace" and "pretending to take advantage of Yu".As a result, Jiajing cut off the prince Zhu Houtan, reduced him to a commoner, and sent him to Fengyang, where he was imprisoned by high walls.

It wasn't until the first year of Longqing, when there was a rebellion in the court, that Zhu Houtan resumed the title of King Zheng, and at the same time gave him a salary of four hundred stones, and returned to Huaiqing Palace.

In the 19th year of Wanli, Zhu Houtan passed away, with the posthumous title of "Gong", and became King Zheng Gong.As the eldest son of Prince Gong, Zhu Zaiyu should inherit the princely title.Moreover, when Zhu Zaiyu imprisoned Fengyang in the Zhu Houtan circle, he built a mud house outside the palace on the grounds that his father was innocent and his son could not enjoy himself. The name spreads far and wide, and it can be said that the name deserves it.

However, starting from the 19th year of Wanli, Zhu Zaiyu went to Shu Wanli Emperor seven times in succession, asking to resign from the country, which is the allusion of "Qi Shu Ci Guo".

The reason why Zhu Zaiyu was so persistent was because of another public case within the royal court of Zheng.

That was the entanglement between the Mengjin royal family and the Dongyuan royal family.

At the beginning, Zhu Qizheng, King of Zheng Jian, had ten sons, among whom Zhu Jianzi, the eldest son, was the future King Zheng Xi; ?——Zhu Houtan's grandfather, Zhu Zaiyu's great-grandfather.

At that time, the mother of Zhu Jianhui, the king of Mengjin, was favored by King Zheng Jian, and wanted to seize the title for Zhu Jianhui, but failed.Later, when Zhu Jianwei stole the gold book of his dead son, King Zheng Jian asked for it back, so he complained to his father and stopped seeing King Zheng Jian, and his behavior became worse and worse. .

King Zhengjian played Emperor Chenghua, causing Zhu Jiansui to be deposed as a commoner, so he was called "Mengjin Abandoned Man".

Later, Zheng Kangwang Zhu Youjian, the son of Zhu Jianzi, died without a son.At this time, the most recent generation of county kings in Zheng Wangfan's blood had passed away. According to the order of seniority, Zhu Youxuan, the son of Zhu Jiansui, should be the heir to the title of King Zheng.But because Zhu Jianwei was guilty and was abolished, Zhu Youxuan, the son of Dongyuan Duanhui King Zhu Jian????

In the 29th year of Jiajing's reign, Zhu Youxuan requested the restoration of the title of King of Jin County, and wanted his nephew Zhu Houtan to perform for him as King Zheng.However, Zhu Houtan had just offended Emperor Jiajing, and he thought it was not appropriate to ask for a seal at this time.Because of this, Zhu Youfan resented Zhu Houtan, so there was a major case of Shangshu accusing Zhu Houtan of treason.

During the 19 years when his father Zhu Houtan was imprisoned by the high wall, Zhu Zaiyu devoted himself to studying. Not only did he have extremely high attainments in science, but he also became more and more deeply attached to the humanities.So when it was his turn to inherit the title, he wanted to completely settle the family grievances, resigned from the country seven times, and refused to inherit the title.Even when Emperor Wanli wanted to establish his son as King Zheng, he insisted on refusing to accept it, and finally gave the title of King Zheng to Zhu Youdu's grandson Zhu Zaigun, completely resolving this family grievance that lasted for five generations.

Zhu Zaiyu finally spent his life as the eldest son, and his grandson, Zhu Changjie, inherited the title of Dongyuan King in the eighth year of Chongzhen.

This is Zhu Changjie's so-called unwillingness to violate his grandfather's original intention.

Starting from Zhu Houtan, this line of clan has been more inclined to literature and science, and being able to inherit a county king is considered content, and they are no longer willing to participate in any battles.Now that King Zheng's whereabouts are unknown, what if he comes back?Rather than causing trouble again, it is better to just decline.
