My life skills in Daming Liver

Sitting in the school building in the torrential rain, Su Ze heard the sound of the rain column hitting the ground outside the window, and his mind drifted to Changningwei again.

During this period of time, the sea-going ships have been retracted into the port, and the ports of Changningwei and Dong'ao Island have been closed, and it is not known whether any ships have been damaged.

The water level of the Minjiang River and Jianxi skyrocketed, and the canal house, which had always been neglected, was also busy. Hai Rui let the county students study for self-study, and was entrusted by Baizhi County to take the officials of the canal house to inspect the water conservancy facilities.

No way, who made the county government officials so few? The official officials in the county were all mobilized to lead the officials to inspect the river dam.

Su Ze is not worried about the water conservancy project of Jianxi. When the Xishushui sand flushing project was built, a channel for flood control and flood discharge had been reserved, and the reservoir was built according to the surplus of the highest water level in history.

However, I heard that there was a dangerous situation in the Minjiang River, and the river almost did not cross the dam. If the villagers did not try their best to block it, it would be a disaster if the Minjiang River burst its embankment.

Baizhi County had lingering fears. If the embankment really broke, he would be the county magistrate for the end. Then he mobilized all the county officials, and finally survived several rounds of danger.

This kind of storm is nothing to Yanpingwei along the coast, but Su Ze is worried about the newly built buildings on Dongao Island.

In addition, Su Ze is also worried about whether the sweet potatoes and potatoes that have just been plowed in the mountains can survive.

The sweet potatoes sown in winter have been harvested in March, and this sweet new food was quickly welcomed by Changningwei.

Whether roasted sweet potatoes or sweet potato porridge are popular in Changningwei, this time of spring plowing, sweet potatoes are planted in the mountain fields near Changningwei.

In fact, sweet potatoes have a lot of water content. When you just eat them, you will feel full, but you will be hungry soon. In fact, as a staple food, it is not as good as rice and wheat.

The advantage of sweet potatoes is that they can be used in emergencies during famines, and the high yields do not require high land. They can be planted in large mountainous areas in Fujian.

Su Ze has already promoted the planting of sweet potatoes in the mountainous area near Changningwei. As for the problem of seedling degradation, insisting on using high-quality varieties to raise seedlings can delay the deterioration of seedlings until four or five generations later. Su Ze still has two or three years to solve this problem .

Continuous torrential rains have also caused problems for tea estates in Mount Wuyi.

In previous years, although it would rain during the Ching Ming Festival, it is rare to see such rainy weather for more than ten consecutive days.

Such torrential rain also affected the picking of tea after the Qingming Festival, and what was worse was that there was no sunshine and the tea could not be dried.

This made the owners of the Wuyishan tea garden very anxious. After receiving the news, Su Ze immediately copied out the method of making black tea and handed it over to Manager Zhou.

The production process of black tea is actually similar to that of green tea, except that the picked tea leaves do not need to be dried in the sun, but are stored in a dark place for a period of time.

But how long to store in the cellar and what kind of humidity to keep, these need to be studied repeatedly to determine the taste.

The continuous rainy weather just gave Su Ze the opportunity to experiment. According to his instructions, the three batches of tea were cellared for different days, and then roasted by the tea house and sent to Su Ze to taste the taste.

"Brother Rulin."

A young man stood in front of Su Ze. Su Ze came back to his senses and said, "Brother Chengzhai."

The young man in front of him was the same age as Su Ze, and he was also a rookie who passed the boy's test this time. His surname was Li, his name was Qiyuan, and his style name was Chengzhai. The style name came from Hai Rui after entering the county school, and he quickly became friends with Su Ze.

"Brother Rulin, I solved that problem yesterday."

Li Qiyuan took out a small piece of paper and spread it in front of Su Ze, only to see dense numbers written on it, it was a math problem.

Su Ze looked at the answer, nodded and said, "Brother Chengzhai, you really have a family background."

Li Qiyuan was a surprise that Su Ze encountered in the county school. Li's family is a small family in Nanping County, who passed down mathematics from generation to generation. I went to help the people calculate the land for buying and selling.

The reason why Li Qiyuan was able to pass on mathematics to his family was because his ancestors had participated in the Four Seas Exam presided over by Guo Shoujing.

The Four Seas Test was proposed by Guo Shoujing, a calendar expert in the Yuan Dynasty. Twenty-seven test points were established across the country to observe the length of day and night and the time of sunrise and sunset throughout the year.

Guo Shoujing calculated the new value of the yellow-red intersection angle through the difference between the sun and shadow at these locations, and accurately calculated the length of a tropical year, accumulating a large amount of data for the compilation of the "Shoushi Calendar".

At that time, there was also a test platform in Fujian, and the ancestors of the Li family were in charge of this test platform.

Li Qiyuan's ancestors also worshiped under Guo Shoujing's Xingzhou School, and learned a lot of mathematics and astronomy.

It was only after the establishment of the Ming Dynasty that learning astronomy privately became a felony, and the Li family was unwilling to enter the Qin Tianjian, so they passed down their anonymity in Nanping County to this day.

The Li family was in decline, so Li Qiyuan and his son could only pick up the arithmetic knowledge of their ancestors again, and make a living by doing land calculations for the people of Nanping County.

"Brother Chengzhai, your push and gather top method is no longer a problem."

Li Qiyuan cupped his hands and said: "Thank you, brother Rulin, for teaching me the method of Zhang Tian."

Li Qiyuan was full of gratitude. The Zhangtian method passed down by Su Ze was more accurate than the method passed down by his family, and it was also faster to calculate than the method passed down by his family.

Since using this method, Li Qiyuan helped his father to give others land quickly and well, earning a lot of word of mouth.

Li Qiyuan continued: "Before I met Brother Ru Lin, I didn't know there was such an exquisite cutting and mending method in the world."

The Zhangtian method handed down by the Li family is actually similar in principle to Su Ze's Pushing and Gathering Method, except that the Pushing and Gathering Method formulates the process and is more convenient to calculate.

Since ancient times, the method of calculating the area of ​​polygons is the "cut and fill method".

Just like calculating the circumference of a circle, Zu Chongzhi's method is to continuously calculate the sides of a circle into small straight lines. In fact, this is a kind of thinking of limit calculus.

Su Ze smiled and said, "Brother Li, I still have an integral method, do you want to hear it?"

Li Qiyuan's eyes lit up, and he sat down obediently, while Su Ze smiled slightly. Don't blame me for calculus Dafa for someone to deliver it to your door!

Su Ze first briefly described the principles of calculus, and then deduced a few simple theorems. Li Qiyuan has completely fallen into the ocean of mathematics.

After officially entering the county school, Su Ze discovered that the life of scholars in this era is not limited to the Four Books and Five Classics.

For a low-level scholar like Li Qiyuan, it is impossible to put all hopes on the imperial examination.

Among Su Ze's classmates is Wang Xun, who studied Daming law in his family. His father is also a well-known lawyer in Nanping County.

There is even a guy named Han Li, whose father is a yin and yang student in the county government.

Yin Yang Sheng is the Mr. Yin Yang who is in charge of calculating auspicious times and days for the yamen.

Yin and Yang students and their children were originally not allowed to take part in the imperial examinations. It was in the second year of Tianshun that the conditions were relaxed and children of Yin and Yang students were allowed to participate in the imperial examinations.

Han Li is proficient in calculating auspicious times and geomantic omens. The county government’s Yin and Yang students don’t have much to do. On weekdays, he also does some “private work” of geomantic omen with his father.

In addition to these two people, there is also a scholar Yu Zongzhang who was born in a military household in Yanpingwei. Zhang is the second son of this hereditary family.

Unable to inherit the family position, Yu Zongzhang could only study hard. To say that this Yu Zongzhang is also very good, Yanpingwei's health school has long been abandoned, and he was admitted to the scholar by borrowing books and self-study.

Among the three, Yu Zongzhang and Su Ze were both from military households, and Yu Zongzhang was Yu Zongyuan's brother of the same clan.

Han Li and Li Qiyuan, one is the son of yin and yang, and the other is the son of a scholar, both are relatively marginalized scholars in the county.

Su Ze expressed kindness to them, and they naturally gathered around Su Ze.

Han Li rushed in and said to Su Ze, "Brother Ru Lin, Inspector Wang is coming to Fujian soon!"

Inspector Wang was Wang Daokun, the Hanlin official that Hai Rui had mentioned before, who was appointed by the imperial court to preside over the imperial examinations in Fujian.

Han Li said to Su Ze: "I heard that this Inspector Wang is especially good at melody. Brother Ru Lin, you will take advantage of this local examination!"

Han Li's loud voice made everyone look at Su Ze.

Su Ze covered his face with his hands, and he didn't know how this guy had such a big mouth.

He is not a person who studies history, so he rarely knows about Wang Daokun, but Su Ze's history is at level 5, and he also majored in Ming history before time travel, so naturally he still remembers the name Wang Daokun.

Wang Daokun is Zhang Juzheng's fellow Jinshi.

Su Ze couldn't help feeling the correctness of the Six Degrees of Separation Theorem. He only needed to contact Zhang Juzheng through Wang Daokun alone.

This also shows how small the circle of top scholars in the Ming Dynasty was, but after stepping into this circle, there will be more or less intersections.

Now Zhang Juzheng should still be "recovering" in his hometown Jiangling, right? He was going to return to the capital in the 36th year of Jiajing, and in less than ten years, he jumped from the editor of the Imperial Academy to the second assistant of the cabinet.

This is the terrifying promotion speed of Hanlin officials, and then Zhang Juzheng took another six years to overthrow Gao Gong and became the auxiliary minister of Emperor Wanli of the Ming Dynasty.

Of course, Su Ze didn't want to make friends with Zhang Juzheng through Wang Daokun. He wasn't even a Juren, so he couldn't get into the Jinshi circle at all.

What made him interested in Wang Daokun was something else.

Inspector, Su Ze really wants to ask, did you write "Jin Ping Mei"?

This wonderful book was written during the Jiajing period. Many people in the academic circle speculate that it was written by Wang Daokun when he was living in his hometown Huizhou.

However, Wang Daokun can be regarded as a member of the imperial court. Naturally, it is impossible for him to admit that he wrote this book. Historians also speculate based on the style of writing and the earliest time when the book was written.

Su Ze always feels a little weird about the school inspector who writes pornographic books.

But the talent of this Inspector Wang is more than enough to be the chief examiner of the provincial examination.

Wang Daokun is proficient in rhythm, folk art, poetry, and is also a famous anti-Japanese general. It can be said that he is a compound talent.

The news that the new school inspector was about to take office spread throughout Nanping County. According to the rules, before the township examination, the new school inspector had to tour the whole province, interview students from all over the country, and test their homework.

Being able to leave a name in the inspector's heart is always a great thing for the rural examination. The scholars in Nanping County who are preparing to participate in the rural examination are holding back their energy, and they want to be a blockbuster when Inspector Wang is touring the counties.

Su Ze is not interested in these things. His current task is to improve the skills of the imperial examination, and brush up other skills by the way.

The rain outside the window was finally a little less, and the sentient beings hurriedly held up the oil-paper umbrella and walked home while the rain was light.

Su Ze was about to go back when he saw Hai Rui returning to the county school in a hurry. He immediately said after seeing Su Ze, "Ru Lin, wait a minute."

Su Ze knew that Hai Rui had something to do with him, so he put down the oil-paper umbrella in his hand and followed Hai Rui to his study.

After wiping off the rain on his head, Hai Rui put on a dry robe and said to Su Ze, "I've finished the first draft of Gu Wen Guan Zhi."

Su Ze didn't expect that Hai Rui could finish the proofreading and typesetting of "Guwen Guanzhi" so quickly when he was teaching the county school and doing disaster relief in the county at the same time.

Hai Rui handed a stack of manuscripts to Su Ze and said, "How long does it take for typesetting and printing?"

"Guwen Guanzhi" in the Qing Dynasty is a collection of essays collected by many masters since the pre-Qin period, and many of the above contents are directly included in Chinese textbooks.

Su Ze's literary skills have been raised to Lv6. He wrote down all the ancient prose in his memory and handed them to Hai Rui to proofread, typesetting and captioning.

Hai Rui was also very interested in compiling this "Guwen Guanzhi". He visited all the families in the city who collected books, and borrowed books from them shamelessly, and then completed the proofreading work of "Guwen Guanzhi".

The "Guwen Guanzhi" of the Qing Dynasty collected a total of 220 essays from the pre-Qin period to the end of the Ming Dynasty. Su Ze's literary level obviously cannot remember so many.

Guwen Guanzhi compiled by Su Ze and Hai Rui only included 50 selected essays. Hai Rui made annotations to explain the allusions and word usage in the ancient prose, while Su Ze was in charge of commenting on the authors and articles.

After flipping through it, Su Ze said, "If printed with movable type, it only takes ten days to bind it into a book."

Hai Rui said with great joy, "I intend to dedicate this book to the new Inspector Wang."

Su Ze was a little grateful, and Hai Rui paved the way for him, wanting to make himself famous.

It would be nice to be able to register with Wang Daokun, Su Ze nodded and said, "Students, let Yinfang publish it."

After talking about "Guwen Guanzhi", Hai Rui said to Su Ze again: "Ru Lin, I heard that you are good at water conservancy?"

Su Ze nodded, and Hai Rui immediately said, "Follow me to Minjiang tomorrow."

Su Ze could only agree. Sure enough, he couldn't afford to be idle. He planned to study hard at the county school during this time, and was dragged by Hai Rui to control the river.

However, the situation of the Minjiang River is not good. Now that the spring plowing has been planted, tens of thousands of people will suffer if the embankment bursts. Now that Hai Rui has found him, Su Ze can't just sit idly by.

Hai Rui added: "Take the book with you. I'll take you to read in your free time."

Su Ze said again: "Teacher, Han Li, a county student, is a yin and yang student passed down in his family. He is proficient in geomancy. The teacher should bring him with him."

Hai Rui nodded and said, "I'll go find him right away."

In the next few days, although it was still raining like a pillar, with Su Ze, the Minjiang River was always tied up in the embankment by means of a combination of dredging and blocking.

At the beginning of May, when the rain gradually subsided, Hai Rui showed a relaxed expression.

Just when Hai Rui returned to the county after the long and dusty flood control, the envoy of the imperial court finally arrived at Nanping County.

Fang Zhifu put down the table and set up a guard of honor at the gate of the government office to welcome the imperial court's order.

For the new chapter, I don't have the audacity to ask for a monthly pass for the time being.

Slow down the plot in these chapters
