January, twenty-one.

After Zhu Shun finished compiling the logic of the seven basic disciplines, he began to write physics and chemistry, which were the two disciplines he was best at.

The youngest doctor in mathematics, physics and chemistry in history is not bought with money.

The heavy snow whistling outside the window finally stopped, and several younger brothers were building snowmen in the yard, and the fifth brother Zhu Tie ran to Wang Gongchang to practice knife skills with Zhu Zhongyi, the general banner.

Today he said that he would take him to the alley near the Candle Temple to clear out a few lamas who were murdering for money, so that Zhu Tie could see blood.

Zhu Shun put down the hard brush in his hand, rubbed his frozen hands that couldn't write, and thought that when he had money one day, he must replace the papier-mâché window with a glass window.

The windproof effect of the papier-mâché windows is really not very good.

It is also necessary to replace it with a good inkstone, and replace it with the kind of inkstone that does not dry in summer and does not freeze in winter.

Zhu Shun stood up and moved his muscles and bones, preparing to continue compiling junior high school textbooks on physics and chemistry, and strive to finish them before the establishment of a new-style school.

Before he could lift the hard brush, the third uncle Zhu Zhongli walked into the courtyard with a middle-aged Confucian student wearing exquisite cotton cloth with a smile on his face.

The middle-aged Confucian wears a pair of Western glasses and an ordinary cotton jacket, just like an ordinary teacher.

Zhu Shun glanced at it, and was attracted by the middle-aged Confucian student, and four words popped up in his heart.

Very stylish.

The third uncle invited the middle-aged Confucian into the main hall, opened his voice and shouted: "Shun'er hurry up, Mr. Song Yingxing is here." ”

When Zhu Shun heard Song Yingxing's three words, he inevitably felt excited to see a famous person in history, walked out of the house, and said with neither humility nor arrogance: "I've seen Mr. Song." ”

Song Yingxing's great-ancestor later served as the secretary of the Ministry of Industry, the secretary of the ministry, and the supreme governor of the Metropolitan Procuratorate.

Seeing Zhu Shun, who was born in the countryside, he still tried in vain to accept his two sons as protégés, but ordinary people would have said that they were not self-sufficient and walked away.

Song Yingxing smiled gently: "You are Mr. Xiao Zhu, I heard that Mr. Xiao Zhu is a pedantic man, Song came to visit today, I hope I didn't disturb Mr. Xiao Zhu." ”

Zhu Shun has never seen such a gentle and elegant Confucian student, and in this cold winter wax moon, it makes people have a kind of comfort like a spring breeze.

With Song Yingxing's reputation in Qingliu, a little Mr. Zhu, and Zhu Shun who shouted were a little ashamed, and smiled indifferently: "Pedants don't dare to say it, but they have some research on geometric arithmetic." ”

A hint of appreciation flashed in Song Yingxing's eyes, but he didn't expect Zhu Shun not only to not have the domineering spirit of a young man, but also to be a dignified celebrity who was indifferent to fame and fortune: "Didn't Mr. Xiao Zhu invite me to a cup of hot tea?" ”

Zhu Shun smiled, took out the junior high school mathematics textbook, and handed it to Song Yingxing: "Drink tea, how can this book make Mr. feel happy." ”

For Ming Dynasty scientists, the most common junior high school mathematics textbook was almost equivalent to the original manuscript of the Analects.

Song Yingxing has studied geometric arithmetic for most of his life, and there are too many questions in his mind compared to his two sons, and he thinks that he has solved a lot of mathematical problems, and he deserves to be a master of geometric arithmetic.

After reading this junior high school mathematics textbook today, Song Yingxing's heart was far more shocked than his two sons.

It's like walking in a cramped cave for decades, thinking that darkness is everything, and crampedness is the boundary of the world.

After reading this junior high school math textbook, a bright light suddenly appeared in front of me, and I walked out in search of the bright light, and my eyes suddenly opened up.

A vast and new world appeared in front of Song Yingxing.

After reading a third of it hungrily, Song Yingxing decisively closed the junior high school mathematics textbook and said with emotion: "Mr. Xiao Zhu's knowledge is far above Song. ”

"Even Xu Guangqi and Wang Zheng are afraid that they are not as good as Mr."

This junior high school mathematics textbook is comparable to the attraction of Wushisan to Wei and Jin celebrities for Song Yingxing, but he still decisively returned this classic to Zhu Shun.

The scholarly family pays attention to the inheritance of culture, and is most taboo to steal other people's knowledge, no matter how difficult Song Yingxing can bear the charm of junior high school mathematics textbooks, he still can't continue to read it.

If this spreads, the Song family's style will be completely ruined.

Zhu Shun handed the junior high school mathematics textbook in his hand to Song Yingxing: "This book will be given to Mr. Song." ”

Song Yingxing has maintained a gentle and elegant attitude for decades, but because of this junior high school mathematics textbook, he almost blurted out a vulgar country dialect and almost fell out.

Taking a deep breath of the cold winter breath, Song Yingxing barely kept himself calm: "Really? ”

Whether it is a bureaucratic squire or a scholarly family, the most important thing is the inheritance of culture, which is the foundation of a clan's foothold, and it is the cornerstone of whether the clan can continue to burn.

Such a classic that is enough for the first assistant of the dynasty to carefully put on the top floor of the library pavilion, saying that it will be given away, Song Yingxing has the feeling of daydreaming for the first time.

Zhu Shun said lightly: "It's just a book, and this is just a textbook I give to students in the future." ”

Hearing the words textbook, Song Yingxing couldn't help but stand up and solemnly saluted Zhu Shun: "Mr. Xiao Zhu is selfless to this point, and he should be a model for my generation. ”

After pretending to be almost, Zhu Shun thought about taking those two world-class geniuses into his pocket: "Mr. Song, do you see the ........matter of accepting apprentices?"

The teacher is solemn.

It takes a certain test for the master to select disciples, and the gentlemen that the disciples worship are often extremely cautious, not to mention the scholarly family like the Song family.

Master's knowledge, conduct, ambitions, and so on are all the same.

In particular, Master's ambition is extremely important, in case Master's greatest wish in this life is to be the emperor, no matter how loyal and patriotic the disciple is, he will rebel.

A teacher for one day, a father for life.

Zhu Shun knew that in terms of knowledge, he must have impressed Song Yingxing, and his conduct was fine, and the rest was ambition.

Zhu Shun didn't directly say his ambitions, but asked Song Yingxing: "Mr. Song, what do you think of the current Ming Dynasty?" ”

Song Yingxing didn't understand what Zhu Shun meant, he didn't understand or pretend to understand, it was another good character of Song Yingxing, and he smiled gently: "If Mr. Xiao Zhu has anything to say, please say it directly." ”

Zhu Shun turned his face to look out of the door, looked at the sky with the cold wind whistling, and said something heartfelt that had been held in his heart for a long time: "In the current Ming Dynasty, the living environment is constantly deteriorating. ”

"Great droughts, great floods, locust plagues....... All kinds of disasters that do not occur once in many years have appeared one after another. ”

"Tens of thousands of poor people often do not have enough food and clothing, and the average life expectancy is only 34 years old at most."
