21. The top of foreign arithmetic, four yuan jade mirror
"Can Taoist Master solve the evil cult this time solve the problem?"
After Wang Yuanzhi confirmed the signs of "Great Heat", he seriously asked about the things in front of him. This matter was related to him. If the ancient god relics were really used by Xu's family in this year's battle to seize the island, it would be a big trouble.
Losing a share of one year is small, and losing a soldier is big.
Or, the majesty is even more casualties. Just imagine, if the Wang family’s two thousand elite soldiers in Poyang Lake were wiped out, even if the Wang family has more than one leg, what do outsiders think?
The greed siege triggered by then will be the real big loss.
Wang Yuanzhi was not allowed to pay attention to this matter.
"This kind of overseas evil worship has never been in contact with in the past, so I dare not boast about it. However, killing demons and eliminating demons is the responsibility of our Tianshi Mansion, and we must do our best!" Zhang Yonghuan expressed his opinion that Wang Yuanzhi naturally believed that it was time to solve this matter and continue to go north.
He ordered the butler to move the people from Cangming Gang and investigate the matter with all his might.
Once there is information, report it immediately.
"The people below have already gone to do it. The Taoist priest hasn't eaten yet. I'll ask the kitchen to prepare and eat it first." Wang Yuanzhi actually noticed that the incident happened in the restaurant, and the food may not be eaten.
After arranging supper and asking his daughter to follow Zhang Yonghuan and his party, Wang Yuanzhi went out to do business.
The emergence of the ancient gods' remains made Wang Yuanzhi realize that the times were really different. The battle to seize the island in April may have to make other preparations, and he had to do many things himself.
While Zhang Zhixiang was having a meal, she was very uncomfortable with the addition of a girl in the room.
Especially that girl has a strong aura...
"Dad said it is safest to follow Mr. Yonghuan. I didn't see you, so you don't have to care about me." Wang Jiangque said without raising his head while sitting in the corner, holding a volume of "Journal of the Principle and the Treasures" in his hand.
I actually know what Zhang Zhixiang is thinking...
"oh."
Zhang Zhixiang responded in shame, lowered his head and pulled a few bites of rice. In fact, it wouldn't be embarrassed if the fourth uncle was there, but the fourth uncle took a piece of cake and went out to draw talismans, saying that if there was something wrong at night, he would go out to deal with it, and the children would be guaranteed to stay in the house.
Da Fangfeng was guarding the yard, and there were only Yushui and Wang Jiangque's maid in the house, two people with a weak sense of existence...
What is the difference between this and being alone?
He was thinking randomly that the rhythm of life after dinner should be reading books or practicing martial arts, but the old master said that he read too many books on weekdays and did not allow him to bring books when he went out, so he only practiced martial arts. He had a look of embarrassment when he was on the boat before...
"Well, are you looking at the Principle Treasure Archive?"
He still found a topic, but he didn't want to chat with him, but when he was learning Taoism with the old master, his senior brother mentioned this book when he talked about external calculations.
"The author of "New Collection of Tokens to Certification of Ancient and Modern Mathematics and Sciences" is Wang Wensu, Shanxi, who was born in Shanxi merchants. He began to circulate the first draft in the eighth year of Zhengde, and the final draft was published in the third year of Jiajing."
"The book has 12 books, 42 volumes, and 500,000 words in total."
"This book focuses on the courage of the 'new collection' and the perseverance of the 'token'. Pay attention to the tokens of all mathematical works that can be seen in the world, so as to achieve the effect of removing the false and retaining the truth, removing the droops and retaining the essence."
"It is a mathematical masterpiece that can correct the origin."
"But that's all. Compared with the level of mathematics in Song and Yuan dynasties, Wang Wensu learned only a limited degree of knowledge about Tianyuan Art and the Four Yuan Art, and he did not deduce it forward."
"Summarize."
"This is a book that is successful, but it has no pioneering action, which is a pity."
Wang Jiangque directly finished all the relevant contents of the Academic Learning Treasure Archive, leaving no room for interruption to Zhang Zhixiang. When answering, he was still turning the pages, which did not affect her reading at all.
Zhang Zhixiang was a little shedded while receiving the teachings.
He didn't know much about ancient mathematics. Wang Jiangque's evaluations were different from the old master, but I think the old master probably hadn't read this book, and Wang Jiangque was reading it, so her evaluation was more accurate.
"So, what is the most successful work in mathematics?"
"The Four Yuan Jade Mirror."
Wang Jiangque said: "Zhu Shijie's "Four Yuan Jade Mirror" in the Yuan Dynasty is the highest peak in the mathematical world. No one has been able to match the 'Four Yuan Technique (Four Yuan High-order Polynomial Equation)', 'Plaid-in-Class Technique (Advanced Arbitrary Sequence Summarization)', and 'Track-in-Difference Technique (High-order Interpolation)', so far, no one has been able to match the Technique."
Zhang Zhixiang didn't understand these professional terms very well, but he could hear that Zhu Shijie of the Yuan Dynasty was the most powerful and no one surpassed him in the Ming Dynasty.
If he expected it was not bad, the four-element technique should be a four-element higher-order polynomial equation, then his mathematics would not have any effect in the Ming Dynasty.
In fact, as long as all time travelers are not majoring in mathematics, they travel to ancient times, and the little mathematics they learn is useless...
You know, there are all in ancient books.
You won't, there are.
"Well, do you know these? For example, the Four-Yuan Art." Zhang Zhixiang asked a question of some failures. He himself didn't know anything. After he finished his high school courses in his previous life, he read some miscellaneous books and was not proficient in mathematics.
"meeting."
Wang Jiangque's answer is very short, but he is very domineering. He is only a seven-year-old girl, but he can learn the most obscure and difficult mathematics works. In comparison, he is like a poor student...
"What else do you...can't do?"
Zhang Zhixiang knew that this question might be a bit humiliating, but he still asked. Although he was a little afraid of Wang Jiangque, this girl who was very wise and close to demons made him feel infinite curious.
Wang Jiangque stopped reading, glanced back at Zhang Zhixiang, and said, "Do you only ask people?"
Zhang Zhixiang:...
After the silence, Zhang Zhixiang sorted out her mood, sat upright, and said, "Then ask me."
"No questions."
“…”
He understood that the girl didn't want to talk to him, and thought he was noisy. He looked outside the door and saw that there was no sign of his fourth uncle coming back, so he planned to go to the yard to find Da Fangfeng to discuss martial arts.
Hey, it’s all because of the rain. Can’t you tell that your young master is embarrassed?
Even the atmosphere will not be broken...
"Big Wind, Big...Big Wind?" After crossing the threshold and coming to the yard, there was no one who saw the Big Wind. Such a giant would never be able to find it. Could it be that Big Wind has gone out?
Even if you go out, you should notify me, right?
Although Dafeng is a giant, he is a very careful person and will not leave without saying goodbye at this time...
Oh no!
Zhang Zhixiang suddenly woke up, and he turned around suddenly, but it was not the door in front of him, but a fog! The whole yard was covered with fog at some time, which made people feel a little panic!
calm……
I just walked five steps away. Now I can walk five steps forward and then go back to the room. At least I can find Yushui and Wang Jiangque and the girls first, so I have to protect them.
One, two, three, four, five, six, seven…
After all seven steps, the fog in front of him seemed to have no end. Zhang Zhixiang's forehead was covered with cold sweat. The more terrible quiet the surrounding moment, the less he dared to look back.
