Through conversation, Zhao Hao learned that Hua Shuyang had been fond of arithmetic since childhood.

Arithmetic is one of the six arts of a gentleman. The Hua family is the richest man in Wuxi, and it really requires children to be good at financial management. Therefore, in addition to his studies, Hua Shuyang specially studied arithmetic with the famous mathematician, Xiuning merchant Cheng Dawei. In addition, he was talented and far beyond ordinary people. He quickly dabbled in the works of predecessors such as "Nine Chapters of Arithmetic", "Zhoufeng Arithmetic", "Arithmetic Treasure Book", "Jiaoshu" and other works.

But he couldn't understand many things, such as Tianyuan Technique and Four Yuan Technique... It was so puzzling that Mr. Hua was still unable to understand it when he asked for advice. Cheng Dawei was already a top mathematician in the world, but he still could not answer questions for Hua Shuyang.

Because since the Song Dynasty abolished the "Ming Arithmetics" from the imperial examination, the once glorious arithmetics in my country have gradually declined. By this dynasty, there were only daily applications left, and few people have studied this subject specifically. Moreover, most of our historical mathematicians are good at arithmetic and solving equations. They are far ahead of the world in terms of calculations of specific problems, but they only regard mathematics as an application and an interest. If they lack speculation on deeper things in mathematics, they naturally cannot axiomatic them.

Axiomization is necessary for future generations to study mathematics systematically and conduct in-depth research. Without this step, it will always be difficult to enter the door of mathematics; they can only admire the achievements of their predecessors and cannot understand them...

Until Hua Shuyang saw the book "Elementary Mathematics" and suddenly found the key to answering those difficult problems. He saw from the book that the author had compiled a complete discipline system. As long as he followed the author to learn all the way, his questions would not only be solved, but he would also enter the classroom and become a master of mathematics.

What made him even more fascinated was that in this book, any assertion can be confirmed or negatively argued, and this argument is rational and objective, and is completely unaffected by any sophistry and authority, and can accept any doubts and refutations!

This is very different from traditional Confucianism. Confucian scholars can only succumb to the annotation of the sages by Confucian scholars of the Song Dynasty. People with a little thinking ability will inevitably have doubts. Therefore, the rebellious study of mind emerged, but study of mind still cannot prove its correctness, and it still follows the old path of idealism.

Hua Shuyang then had a bold idea. If he could base his knowledge on the basis of mathematics, study the world with mathematical methods, and then axiomize it, wouldn’t he find the absolute truth that could stand the test of anyone?

No matter how proud Hua Shuyang was, he could not resist this temptation. So he made up his mind to take Zhao Hao as his teacher even if his father-in-law didn't let him enter the door!

Anyway, my wife has been married, what are you afraid of?

At worst, kneel on the washboard at that time...

One of them was determined to become a disciple, and the other was willing to accept disciples. It was a fire and fire, just a little bit.

Zhao Hao made a little artificial, and sighed helplessly: "I originally didn't plan to accept another disciple, but first of all, Wu Yang said a lot of good things for you; secondly, there are not many scholars in this world who are willing to learn mathematics. In order not to let this knowledge be lost, I will make an exception to accept you."

"That's great!" Hua Shuyang was extremely surprised. He had heard Wang Wuyang say that he almost fainted at the beginning, and he was pitiful to his master and was under his sect. Unexpectedly, it was his turn, but he only knelt for an hour...

It seems that I like it more than Master Six…

Hua Shuyang happily bowed to Zhao Hao four times, and then stood up to pay homage to Wang Wuyang, the senior brother.

Wang Wuyang was still a little tasty, but he thought to himself why his master didn't make things difficult for him? But when he heard Hua Shuyang change his name to him, he suddenly woke up.

No matter how many disciples my master will accept in the future, I will be the senior brother of Kaishan, and they will all respect me!

If you think about it, Wang Wuyang regained his bright smile and helped Hua Shuyang up and bowed with a smile and said, "Don't worry, senior brother, I will teach you well."

"Thank you, senior brother..." Hua Shuyang originally thought that Wang Wuyang just said something on the spot. Unexpectedly, this senior brother was serious...

After lunch that day, it was time for Zhao Hao to take a nap.

Hua Shuyang also wanted to find a place to take a nap, but Wang Wuyang pulled him to Gao Wu's room and asked him to change his slutty hibiscus flower brocade robe and put on a large shuttle cloth narrow-sleeved short robe like himself.

Hua Shuyang fiddled with his narrow cuffs and couldn't help but smile: "Are you going to ride and shoot? I haven't worn this style yet."

"Wearing well is not only convenient for riding and shooting, but also for work." Wang Wuyang threw a rag to Hua Shuyang and said, "Wrapping all the furniture, desktops, bedsides, and windowsills in the room, don't make any noise, which will make your master have a lunch break."

"Ah, I still have to work?" Hua Shuyangjun's face was full of surprise. The richest man in Wuxi and the son of Taishi Hua, but his ten fingers are not touched by Yangchun.

"Nonsense, didn't you see it all that day?" Wang Wuyang said with a blank look: "After I entered the door, I worked every day, and I didn't take a day off."

After saying that, he lay on Gao Wu's bed, stretched and said, "It's considered that someone is working for me..."

Gao Wu would go to the front to help at this time, and Wang Wuyang happened to occupy the magpie's nest and took the opportunity to stare for a while.

"You..." Hua Shuyang then realized that what Wang Wuyang said that day was true. Looking at the rag in his hand, he still asked unwillingly: "What can I let Shutong do?"

"No, Master said that you must practice everything yourself and practice it yourself to hone your mind." Wang Wuyang shook his head decisively.

Hua Shuyang asked dejectedly: "I have to do it by sweeping the yard, serving tea and pouring water, pinching shoulders and squeezing the back, washing and picking vegetables?"

"It's also indispensable." Wang Wuyang closed his eyes comfortably and said, "How can you get rid of your arrogance if you don't do this? How can you find a innocent heart if you don't do this? How can you stop being impetuous if you don't do this?"

"Uh, okay..." Hua Shuyang thought it was reasonable. Wang Wuyang was also the prince of the Wang family. He could give up his posture and do the work he had no reason to do. Otherwise, wouldn't he let his master down?

Thinking of this, he picked up the basin, took the rag and started working.

An hour later, when he was about to wake up, Wang Wuyang also stretched out from Gao Wu's room and saw that Hua Shuyang was still rubbing the windowsill.

He reached out to wipe the place where Hua Shuyang had just passed, then pointed his finger and said, "There is still dust, it's not wiped clean."

"This is outside, is it so serious?" Hua Shuyang rolled his eyes and muttered in a low voice: "It's raining all day long, how can I wipe it clean?"

"Do you think this is just for you to work?" Wang Wuyang put on the air of a senior brother and taught a lesson: "This is practice, do you understand?"

"I'm learning mathematics, not sweeping the floor and wiping the floor!" Uncle Hua was so angry that he threw the rag on the ground.

"How can you wipe out the world if you don't sweep a room?" But Zhao Hao stood at the door with his hands behind his back.

Qiaoqiao almost got angry when she heard this. If you want to be lazy, Caijia Lane, is there anyone who can compare with you, Mr. Zhao in Jinling City?

Why are you so proud to educate your apprentice like this?

Unexpectedly, Hua Shuyang showed a teaching expression, bowed and picked up the rag and said, "Master, I was wrong..."

"Just know your mistake, work hard." Zhao Hao didn't expect that his words would be so worthwhile in his second apprentice's heart, and he was embarrassed to pretend for a while.

He said to Hua Shuyang with a gentle voice: "Since you are going to take the provincial examination, don't be distracted by mathematics for the time being. First, work with Wu Yang to study and write an essay. If you can get the Jie Yuan exam, I will give you a general lecture on "Elementary Mathematics"."

"Yes, Master." Hua Shuyang's eyes lit up immediately and he felt energetic in his work.

"Master, didn't you let me win Jie Yuan too..." Wang Wuyang said in a panic: "There is only one Jie Yuan?"

"That depends on which of you is capable." Zhao Hao said with a smile, then glared at him and said, "You don't bully your junior brother in the future. You need friendship and mutual assistance among your classmates. Do you remember?"

"Yes, Master." Wang Wuyang was naturally more obedient than Hua Shuyang.

"Why don't you go picking vegetables quickly if you know!" Zhao Hao waved his hand and drove Wang Wuyang to the kitchen.

"In fact, they don't need their help." Qiaoqiao brought Zhao Hao a plate of longans and whispered: "Originally, one was fine, but now the two apprentices work, I'm almost out of work."

"Don't worry, they don't know how to cook." Zhao Hao smiled and comforted Qiaoqiao, saying, "If you really have nothing to do, you can help me peel the longan."

"I think beautifully!" Qiaoqiao reached out and slapped Zhao Hao in the head, turned around and ran away.

Zhao Hao smiled and sat back on the chair, peeling the crystal clear longan while looking at the rainbow quietly appeared in the east sky, and couldn't help but feel a little drunk.
