One kick to the Three Kingdoms

Chapter 361 Teaching Arithmetic
On the second day after returning to Tianjing Pass, Qin Yi received a letter from Cao Ren.The letter stated that yesterday, after dark, Niu Fujun suddenly launched an attack on Yewang County, almost breaking through the west gate of the county seat.Cao Ren also told Qin Yi that he was worried about the war in Yanzhou, and wanted to quietly withdraw from Shuinan Pass tonight, then pass through Tianjing Pass, enter Shangdang County, and then divert to the east and return to Yanzhou by detour.

After reading the letter, Qin Yi understood that Cao Ren was reminding him that I am leaving and no one will guard the door for you, so you can take care of yourself.

Qin Yi called Xi Zhicai, Xu Huang, and Zhao Yun together to discuss the matter.

Xi Zhicai said: "Cao Ren wanted to go back to Yanzhou, we expected it, but we didn't expect him to be so impatient. Once he leaves, we will face Niu Fujun directly."

Qin Yi smiled slightly: "It's going to rain, mother is going to get married, these are things we can't control, let him go. It's just that Niu Fu will attack the city at night. Could it be that he is already eager to take down Yewang County? Is it? Wang Xu doesn't know how long he can hold on."

Xi Zhicai thought for a while, then suddenly frowned, and said, "As I expected, Dong Yue and Yang Ding also started attacking Xiangling."

"Sir, what do you mean... Niu Fu is afraid that Dong Yue and Yang Ding will attack Xiangling City, so he is eager to attack Yewang City?" Qin Yi had a guess when he heard Xi Zhicai's words.

Xi Zhicai nodded, and said: "Niu Fu is the commander-in-chief of all armies, and he has more troops than Dong Yue and Yang Ding. He is also attacking a county. If Dong Yue and Yang Ding attack the target first, Niu Fu Fu lost face. Therefore, he was eager to attack Yewang City."

"So, Niu Fu will definitely launch an attack on Ye Wang today, and it will be a violent attack." Xu Huang said immediately.

Zhao Yun also said: "When Wang Kuang died, Wang Xu was in grief. I am afraid that his will will be disturbed, and the morale of the Hanoi army will be greatly affected. Yewang County... I am afraid it will not be able to hold it!"

"Sigh, we retreated to Tianjing Pass without saying hello to Wang Xu. If Cao Ren leaves again, Wang Xu will scold us to death." Qin Yi smiled wryly and sighed.

"There's no way around this." Xi Zhicai said, "What I'm worried about is, if Yewang County falls, will Niu Fu turn around and attack Tianjing Pass."

Qin Yi said: "The Tianjing Pass is so dangerous, Niu Fu probably wouldn't have taken the Tianjing Pass as his goal before taking down Shangdang County. Anyway, the matter has come to this point, let's stay the same."

"That's the only way to go." Xi Zhicai said.

………………

In the evening, Qin Yi received a scout report saying that Niu Fujun stormed Yewang County for a day, and the defenders suffered heavy casualties. Wang Xu led 2000 people to break through from the east gate, and was ambushed by Niu Fujun Li Su. Wang Xu only led more than 500 people to continue. Flee eastward.Yewang County fell.

After receiving the news, Qin Yi met Xi Zhicai again.Both of them believed that Wang Xu must have fled back to Huai County.But Huai County will not last long.

However, having said that, Yewang County has fallen, and after Niu Fujun enters the city, he will inevitably take a rest. Within a day or two, he will not attack other targets.

Although Qin Yi's verbal opinion was consistent with Xi Zhicai's, his real thought was - after a day or two of delay, the news of Dong Zhuo's killing should reach here, and by then, the war should be over up.

In the evening, just after midnight, Cao Ren arrived at Tianjing Pass with his soldiers and horses.Qin Yi and the others stayed up all night, waiting for Cao Ren.

After Cao Ren entered the pass, he only had a quick meeting with Qin Yi to express his guilt. Then, he declined Qin Yi's kindness to let them stay overnight at Tianjing Pass, insisted on going on the road overnight, and returned to Yanzhou.

Qin Yi understood that Cao Ren was in such a hurry to leave, firstly because he was embarrassed to face Qin Yi; secondly, he really wanted to return to Yanzhou as soon as possible to help Cao Cao resist Zhang Ji.

After seeing off Cao Ren's army, everyone went back to their rooms and went to bed.

Everything that needs to be done has been done, Qin Yi now just waits for Niu Fu to withdraw.Nothing happened, on the second day, he began to teach Xi Zhicai the mathematics of later generations.

Qin Yi did not teach directly, but told Xi Zhicai that he wanted to compete with him in arithmetic.Qin Yi also recruited Xu Huang and Zhao Yun as the examiners.

At first, Xi Zhicai thought that Qin Yi was just out of boredom, and was learning arithmetic with him to pass the time.However, after Xu Huang and Zhao Yun each asked a question, Qin Yi didn't resort to calculations, but just used a quill pen to write and draw on the paper to count the time, and then reported the answer.However, Xi Zhicai had to go through a long calculation before arriving at the same answer as Qin Yi.

Now, not only Xi Zhicai was shocked, even Xu Huang and Zhao Yun were shocked by Qin Yi's arithmetic skills.The three of them immediately gathered around Qin Yi to read what he wrote.But they saw that Qin Yi's writing on the paper was full of ghostly symbols, and they didn't know a single word.

After showing off, Qin Yi said proudly: "What I just used is a mathematical method invented from a certain effect in the Western Regions. My teacher once traveled to various countries in the Western Regions and learned this method, and later used this method. The method was taught to me."

"Then what do these words mean?" Xi Zhicai asked curiously, his eyes showed a strong thirst for knowledge.

Qin Yidao: "If you are interested, sir, I can teach you this mathematical method."

When Xi Zhicai heard this, his eyes suddenly brightened.Afterwards, he immediately bowed to Qin Yi and said, "My lord, I am willing to learn. When will I perform the ceremony of apprenticeship?"

"Teacher Appreciation Ceremony?!" Qin Yi was stunned, "Who worships whom as a teacher?"

Xi Zhicai was also stunned: "Of course I worship the Lord as my teacher. Otherwise, how can I learn this arithmetic method from you?"

Seeing Zhicai's natural look in the play, Qin Yi suddenly realized.The gap of the times, the gap of the times.In this era, people regard knowledge and various technologies as treasures, and the inheritance of knowledge and technologies is only carried out between father and son, master and apprentice. Without these two relationships, others will not teach you.

Last year, when he took out the sketches of the new farm tools and handed them over to the craftsmen he recruited to make them, he also experienced the situation like Xi Zhicai's now.Those craftsmen wanted to worship him as their teacher, and they all looked flattered.Poor Qin Yi, facing a group of old craftsmen who were old enough to be his father and even grandfather, he was really scared.It took a lot of talking before he dispelled the idea of ​​those craftsmen worshiping him as their teacher.

It is precisely because of this self-cherishing behavior and tradition that it limits the development and popularization of knowledge and craft technology, and also causes the loss of many advanced craft technologies in history.

"Sir, don't do that. Qin taught you this calculation method just to make it easier for you to handle military and government affairs. Speaking of it, Qin still has selfish intentions. Sir, don't talk about apprenticeship, you and I can learn from each other " Qin Yi quickly stood up, and Chao Xizhi returned a salute.

"This...this...my lord, you are...really..." Xi Zhicai was grateful and shocked at the same time, and became incoherent.

Qin Yi smiled and said: "I'm not a person who hides personal interests. Mathematical learning is the foundation of a lot of knowledge. The more people master it, the more conducive to the development of the entire society. At least, it is beneficial to the government affairs, Military affairs and people's livelihood economy. Therefore, I hope that after mastering the arithmetic method I want to teach, he will not keep it private, and then teach it to more colleagues, so that they can also use advanced arithmetic skills to handle official affairs."

Xi Zhicai saluted Qin Yi again, and said, "The lord has such a heart, no saint is like this! Don't worry, my lord, Xi will definitely take you as an example, and teach what I know and learn to more people." .”

saint?Damn it, my buddy became a saint if he didn't pay attention!
"Second brother, can you also teach me this arithmetic method?" Zhao Yun asked shyly.

Xu Huang also said: "Second brother, I also want to learn."

"Come, come, come, anyone who wants to learn." Qin Yi waved his hand carelessly.Then, he turned to look at Pei Ji who was standing at the door.

Seeing Qin Yi looking at him, Pei Ji said hastily: "My lord, although I really want to be like Mr. Xi who is full of... full of knowledge, but I really don't have enough brains, and I get a headache when I hear you talk about knowledge. You Just don't embarrass me."

ah?This guy thought I wanted to force him to learn arithmetic too!

"Hahaha, Yuan Shao, you have made a lot of progress, and you actually know the idiom "full of knowledge." Qin Yi laughed.

Pei Ji scratched his head, and said, "I follow my lord all day long, listening to you talking with Mr. Xi, Captain Xu, and County Magistrate Zhao, I learned something."

"Well, not bad!" Qin Yi nodded, "Yuan Shao, it seems that you are still very curious. It is a good thing to be able to learn. However, if you don't want to learn, I won't force you. I want you to Go out and have a look, the civil servants in the army, whoever is idle, have also called here. Listen to my lecture together."

"Oh, I'll go right away!" Yuan Shao suddenly realized.

"Look around again, if you can find a wooden board and agglomerated lime." Qin Yi reminded again.

"Understood." Yuan Shao replied and walked out.

Not long after, three civil servants walked into the room.After they saluted Qin Yi, Xi Zhicai and others, Qin Yi asked them to sit aside.

"Everyone, Mr. Qin called you here because he wanted to teach you a very simple and fast calculation method..."

As soon as Qin Yi said the words, those civil servants were shocked.Noticing that their expressions were different, Qin Yi immediately said: "You don't need to make a fuss, and you don't need to think about worshiping me as a teacher. What I want to teach you is just to improve your efficiency in doing things."

After all, these people's official positions were too low, so they listened to what Qin Yi said, but they didn't respond any more.

Qin Yi continued: "Everyone's talent is high or low, so I'm afraid I won't be able to take care of everyone when I teach later. You can remember as much as you can listen to. If you don't understand, you can learn from others." Quick people ask for advice."

As soon as he finished speaking, Pei Ji came in with two soldiers carrying a wooden plank.In Pei Ji's hand, he was still holding a few pieces of lime that had solidified.

Qin Yi asked the two soldiers to lean the wooden boards against the wall, and he asked Pei Ji to use a dagger to whittle the pieces of lime into rough chalk, and then he began to give lectures.
