Chapter 8 Multiplication Mnemonics

  Before this, Wei Wensheng was the actual ruler of Daxing City.

  Wei Wensheng himself was the Minister of Justice and concurrently the Governor of Jingzhao, and with the added identity of being the teacher who taught the Crown Prince, he suppressed Guan Yu tightly, and even the two veteran generals Xu Shu and Yin Shi also gave him three points of courtesy.

  However, the greatest source of Wei Wensheng's power is the imperial power, and the link is the Da Wang Gongxia. Now that the Da Wang Gongxia has suddenly started to seize power, the first to be affected is Wei Wensheng.

  Wei Wensheng was hesitant, and it would be more painful for him to hand over power easily than to kill him.

  However, if he were to desperately suppress the Crown Prince, he might be able to succeed for a while. But as the Crown Prince grows up, the backlash will inevitably become stronger and stronger.

  Moreover, he had suppressed the Crown Prince's mansion, so how would the Emperor view him? Thinking of Yang Guang's unpredictable tactics, Wei Wensheng couldn't help but shiver.

  Master, Pan Wenlin softly interrupted Wei Wensheng's contemplation.

  Wei Wensheng looked up and gazed at his proud student. He knew that Pan Wenlin was usually very opinionated.

  "What's on your mind."

  Pan Wenlin furrowed his brow and fell silent for a moment.

  Suddenly, Pan Wenlin's expression changed and he said: "Master, do you know what happened when the king returned to the palace?"

  "Huh?" Wei Wensheng was somewhat perplexed.

  "When the King returned to Tongguan, it was during the rebellion of Dai Huai's son Sun Hua. The imperial court ordered Tongguan to be sealed off, on one hand to prevent any loss at Tongguan and on the other hand to block a large number of refugees from entering the pass. The King pitied the miserable state of the refugees and ordered the gate to be opened to allow them to enter..."

  Pan Wenlin did not continue speaking, he knew that Wei Wensheng, who had been through ups and downs in his life, understood what he meant.

  Wei Wensheng's eyes lit up, and he thought to himself: since the Crown Prince wants power now, no one can stop him. Why not just give him some power, consider it a test for him, and this way, there will be an excuse in front of the Emperor.

  I'm not saying I don't support the Crown Prince, after all he's still young and will benefit from some experience.

  As for Yan Juncheng, Wei Wensheng had long wanted to knock some sense into him.

  Thinking of this, he selected more than a dozen folded papers from his case and handed them over to Pan Wenlin.

  "Tomorrow morning, find someone to hand these receipts over." said Wei Wensheng.

  "Yes, Master." Pan Wenlin took the folded paper and bowed respectfully before leaving the room.

  ............

  In the Western Garden.

  Yao Si Lian had just finished his lesson and slipped away, while Wang Dian Xia suddenly became diligent and studious over the past few days. However, he asked some basic questions that made him feel embarrassed several times.

  As soon as Yao Suli left, Yang You immediately prepared to slip away. As an old hand in the school, it was essential to slip away immediately after class. Before he could make a move, he was blocked.

  "You really finished checking the Ministry of Revenue's documents in just half a time unit and even found problems?" Yang Jier asked with an incredulous tone. But her curious big eyes betrayed her thoughts.

  Daxing was so big, Yang You's three rejections of the Ministry of Revenue's monthly settlement draft were quickly spread, and just a short while ago, Wei Fei had already sent someone to ask about it.

  Yao Si Lian, who was pinching his nose while teaching some enlightenment knowledge, also took a few more glances at him during class.

  Of course; Yang Jie'er's slightly adoring gaze made Yang You feel very pleased.

  I'm actually a math genius, want me to teach you?

  "Hmph," Yang Jier snorted and turned away. "I know you were able to calculate so quickly because you used the heavenly stalks' numerals. The heavenly stalks' arithmetic instruments have already been presented to the Emperor and are stored in the palace, I've had the palace maid look for them."

  "Just wait a minute, I'll learn it myself and won't need you." Yang Jier said haughtily.

  Yang You was also somewhat surprised, willing to use the common mathematical knowledge of later generations for himself, and should not have expected anyone to recognize it, but unexpectedly, someone on the current prosperous imperial court actually recognized it.

  Gu Yi didn't come from afar, but was able to gain Yang Guang's appreciation, largely due to his knowledge of mathematics. The first time Gu Yi entered Yang Guang's line of sight was when he made a remarkable achievement in investigating a corruption case.

  He used his own knowledge of astronomy to find the problem in the shortest time and received great praise from Yang Guang.

  One does not do two without rest, Gu Yi once again presents Tianzhu's mathematical knowledge to Yang Guang, and gets Yang Guang's favor, from then on rising to high positions.

  However, for some reason, Yang Guang put this mathematical knowledge on a high shelf.

  This time Yang used Arabic numerals and was soon seen through by the officials, who all thought he had obtained the mathematical formula from Bone Instrument, without suspecting anything else.

  What they didn't know was that Yang Hui used knowledge from over 1,400 years later, which was far more advanced than the astronomy of ancient India.

  The only one who had doubts was Gu Yi, because even he himself couldn't have figured it out within half an hour, and these doubts were impossible for him to express.

  Being an official in a foreign land, Guan Yu's secret to serving as an official for many years on this magical land was to cling tightly to the royal family's thigh and serve them to the greatest extent possible.

  Before long, a palace maid rushed in hastily.

  "Your Highness, this is the celestial mathematics you wanted." The palace maid held a thin book in her hand, wiped it clean and presented it to Yang Jier.

  Yang Jier hastily took the book in her hands and couldn't wait to start reading.

  This book on Indian mathematics has yellowed, but the whole book is well preserved, and it's clear that not many people have used it.

  Looking at Yang Jie'er flipping through the book and muttering to herself, Yang You knew that Yang Jie'er, who was enthusiastic about everything for only a few minutes, would not be able to learn any useful knowledge from this Tianzhu arithmetic book.

  Last time, Yang Jie used a peacock feather to write, but it was all destroyed in her hands within an hour. On the other hand, Yang Ji'er learned arithmetic from Yang You and this made him surprised.

  Yang You suddenly felt that the imperial family's library was very necessary to visit a few more times, as the former capital, the Daxing Palace's library must have a large number of rare and precious books.

  You will definitely use some knowledge that is vastly different from this era, and the imperial library will be a good excuse at that time.

  What the hell is this thing.

  Sure, here is the translation:

  As expected, after a while, Yang Jier discovered that she really had no way to deal with those ghostly symbols, and threw the book aside, getting annoyed and frustrated.

  It's actually quite obvious that this profound subject of mathematics can only be appreciated after one has mastered it, and then the endless subtleties will be felt. But for outsiders, it's simply like listening to a heavenly book.

  "Alright, I'll teach you myself." Yang You had no choice but to take matters into his own hands.

  Yang Jier didn't dare admit that Yang You was smarter than her, but she still perked up her ears and listened.

  It's actually a big trick, the most important thing is to memorize the multiplication table. Yang You proudly held his peacock feather pen and wrote down the Chinese characters and Arabic numerals from one to ten on the paper.

  One times one is one, one times two is two...

  Watching Yang Jie'er seriously reciting the knowledge of past life enlightenment with him, Yang You felt secretly pleased at the same time, but always had a feeling that something was not quite right.

  Suddenly turning his head, Yang Yu saw Yao Si Lian eavesdropping outside the window and suddenly realized that he had also fallen into the same trap of teaching enlightenment knowledge.

  What's going on in this world!
