The cow man who Liu He was talking about in his mouth that could delay Lu Zhi's life should be called a miracle doctor to be exact.

Tao Kuan called Zhao Ai'er a goddess doctor, in fact, there are many elements of gratitude, of course, it is not excluded that Zhao Ai'er does have some skills in healing injuries and diseases. However, if you compare Zhao Aier with the cow in Liu He's mouth, it is estimated that there is still a distance of several streets.

The name of the divine doctor is Hua Tuo, the character is yuan, Pei Guo is a person, has been close to knowing the year of the mandate of heaven, now lives in Pengcheng, every month with three apprentices Wu Pu, Fan A and Li Dangzhi, active in Xuzhou, Yuzhou, Qingzhou, Yanzhou all over the place, trekking through mountains and rivers, treating diseases and saving people, while looking for a variety of cherished herbs and folk remedies, so it is deeply loved and respected by the people of Sizhou.

Youzhou is thousands of miles away from Pengcheng, Xuzhou, separated by Gongsun Zhan, Han Fu, Yuan Shao, Tao Qian, Kong Rong, Cao Cao and many other powerful forces, Liu He wants to invite Hua Tuo to the north, how easy is it to say?

For this matter, Liu He already had a plan in his heart, but because the timing was not right, he passed by and asked Liu Fang about Jicheng instead.

Liu Fang reported to Liu He in detail a series of actions after Liu Yu returned to Jicheng, and when Liu He heard Liu Yu's request for the three Taozi brothers to go to Zhuo County to pay their filial piety, he couldn't help frowning.

"Ziqi, do you think Liu Bei will take his two righteous brothers to Zhuo County to pay tribute to the dead county order?" Liu He asked.

Liu Fang shook his head and replied: "I think that Liu Xuande will definitely find all kinds of reasons and excuses to shirk it, and he will not really go to Zhuoxian." ”

"Then what do you think my father is asking Liu Bei so much?" Liu He asked again.

"I think that Lord Taifu is asking for this, it seems that he is laying out for the future crusade against Gongsun Zhan."

Liu He nodded, understanding Liu Fang's analysis.

Liu Bei, as a subordinate of Gongsun Zhan, his brother-in-law committed the crime of killing officials, and Liu Yu just asked their three brothers to go to Zhuo County to pay tribute to the dead county order, which didn't seem excessive, but it was a bit humiliating. After Liu Bei claimed to be King Jing of Zhongshan, he was also a descendant of the dignified Han family, although his status was not as respected by Liu Yu, he could not agree to such a request, so this matter was destined to have no result. In this way, Zhang Fei's killing of the official has become a lead, once Liu Yu feels that he has the strength and needs to use force against Gongsun Zhan, he will bring up the old matter again, and use Gongsun Zhan's lax control as an excuse to raise the army to fight.

After talking about Jicheng, Liu He turned his head and asked Xu Miao: "Jingshan, why don't you also stay in Macheng and assist me in handling the political affairs of Daijun and Shanggu?" ”

When Xu Miao heard this, his face was overjoyed, and he knew that this was Liu He's official recruitment to him, so he hurriedly got up and saluted Liu He, and said: "It is Miao's luck to be able to serve the eldest prince!" ”

That night, Liu He held a banquet in the mansion to welcome the arrival of Liu Fang and Xu Miao.

Although Zhao Aier is a woman, her identity is not humble, she is Zhao Cai's sister, she is talented, good at music, and she is also a well-known woman in Jicheng.

Liu Fang and Xu Miao are now also people around the son, of course, they know the reason why Zhao Ai'er appeared in Macheng, so they frequently raised a toast to Zhao Ai'er during the banquet, and picked up some beautiful words of praise to compliment her, which made the fairy sister a little confused.

When Liu He held a banquet in the mansion, Shi A accompanied Murong Ping to drink "" in the inn.

Last time, Liu He assigned Ding Guo to go to Rongcheng to recruit Sun Li, and Ding Guo completed the task very beautifully, which can be evaluated by consummation. This time, Liu He asked Shi A to approach and observe Murong Ping, not out of a consideration for psychological balance. Ding Guo found a brave young general Sun Li for his son, and he made great achievements within a few days of arriving in Jicheng, and his face was naturally very bright; Shi A, as a senior brother, if he can successfully recruit Murong Ping for his son this time, then the two senior brothers can be regarded as equal.

In addition to Shi A and Ding Jing in the room, there are also several Sima and military marquis who are the commanders of the army, all of whom are rough and atmospheric men, and they gather together to eat meat and drink wine, and the atmosphere is naturally very warm. Shi Ah has the "support" of the son, and he is not stingy with money, and he buys a table of wine and food very richly, and almost buys back all the high-quality meat and vegetables that can be bought in the shops in Macheng.

Shi A picked up the wine bowl and said to Murong Ping: "When I saw Brother Murong today, I felt that you were burly and strong, you are really a mighty and difficult man!" ”

Murong Ping also picked up the wine bowl and said, "Brother Shi has won the award!" When I first arrived in Macheng, I was able to get so many brothers to receive me warmly, and I was grateful to him, and I could only borrow wine to show it! ”

A military commander said: "You two don't learn from those scribes here, pretend to be sour, hurry up and drink, drink!" ”

Then the crowd laughed, raised the bowl and poured it violently.

At this time, the alcohol content of the wine sold on the market will not exceed 15 degrees, which is about the same as the rice wine of later generations, so as long as you are a man, you can drink seven or eight bowls, which is not an amazing mass.

Murong Ping came to Macheng this time because he heard the rumors that Liu He had defeated Xianbei Kebineng in the revenge water, so he deliberately defected and wanted to make a difference.

Although Murong Ping reverted to his surname Murong, he was not a Xianbei person, but a descendant of the medieval tribal leader "Gaoxin Clan". This Gao Xin clan is the name of the third emperor in the "Three Emperors and Five Emperors" in the Middle Ages, and Emperor Yu is the great-grandson of the Yellow Emperor, the ancestor of Yan and Huang.

During the reign of Emperor Huan of the Han Dynasty, Xianbei divided and ruled into three regions, central, eastern, and western, while central Xianbei was ruled by Ke Zique, who lived in the area of Murong Temple at that time, so he changed his surname to Murong.

Since the Xianbei people began to use Murong as the surname of the clan, Murong Ping, who has always been proud of his ancestors for the Gaoxin clan, felt angry, and he thought that the cruel and ignorant Xianbei people used the surname Murong to simply defile their ancestors, so deep down there was an idea of eradicating Murong Xianbei and "cleaning the door" for the Gaoxin clan.

As the wine became more and more drunk, everyone became more and more familiar, Shi Ah intentionally or unintentionally asked Murong Ping why he came to Macheng to serve the eldest prince, and Murong Ping didn't feel that there was anything wrong with his idea of getting rid of Xianbei Murong, so he told his intention.

Several military leaders who came to accompany the wine were all Han Chinese, and they naturally had no good impression of the Xianbei people who were committed to predation, and they also applauded Murong Ping's ambition, saying that in the future, they would definitely help Murong Ping eradicate all the Xianbei people who dared to use Murong as their surname, and return the descendants of the Gaoxin clan to a clean slate.

After drinking, someone called Murong Ping and invited him to go to the barracks tomorrow to test archery and martial arts, Murong Ping agreed, and he was not worried about whether his archery and martial arts could pass.

In the middle of the night, everyone dispersed, and Shi Ah returned to the mansion and reported to Liu He alone.

After listening to this, Liu He nodded and said, "Today's arrangement is good, let those military leaders take a good test tomorrow for Murong Ping's martial arts." In addition, you immediately find two quick-witted and tight-mouthed soldiers from the camp and send them to Murong Ping's hometown to inquire about what he said to see if what he said is true! ”

Shi A received the order and quietly exited Liu He's study.

Early the next morning, Liu Fang and Xu Miao came to Liu He's room together and received their first task after coming to Macheng.

Liu He picked up a thick stack of Caihou paper from the bookcase, handed it to Liu Fang, and then said: "This is a transcript I wrote down when I exercised in various camps in the city in January recently, which involves all aspects of army building and governance, some of which are fragmented and loose, and I ask Ziqi to summarize and sort it out for me." If you encounter a word you don't know, come and ask me. ”

When Liu Fang heard that Gongzi actually said that he had encountered a word he didn't know, he went to ask him, he was a little unconvinced, and felt that he seemed to be a little higher than Gongzi's knowledge, okay?

Liu He handed out a stack of Caihou paper to Xu Miao, and then said: "Jingshan, during this time, I have asked people to conduct a thorough survey and investigation of the types of workshops, shops, and circulating goods in Macheng, and these numbers on the paper are all original records, I need you to help me count and summarize, it is best to be able to list a detailed table, so that it is easy to grasp and remember." ”

When Xu Miao heard that Gongzi asked him to make a "form", he was stunned on the spot, the form is a magic thing? Am I not here to assist Childe in dealing with military affairs? How did you do Cao Peng's work?

Seeing Xu Miao stunned, Liu He's heart was dark for a while, and he said with a serious face: "If Jingshan is not familiar with how to draw forms, you can ask Ziqi for advice first, or you can ask me directly." ”

Liu Fang studied with Liu He in Jicheng for a period of time, and has progressed from the initial memory of number symbols, punctuation marks, and operation symbols to the level of calculation and tabulation statistics on paper.

Mathematics is the foundation of all natural sciences, although the Han Dynasty has formed the system of ancient Chinese mathematics, and there are such mathematical works as "Zhou Ji Sutra" and "Nine Chapters of Arithmetic" that are leading the world at that time, but because of the influence of Dong Zhongshu's "exclusive respect for Confucianism" thought, the vast majority of scholars are unwilling to spend their energy on arithmetic, but ponder Confucian scriptures all day long, one by one they also sit and talk about the Tao, but disdain in natural science.

As a descendant, Liu He is very aware of the irreplaceable role of mathematics in promoting the progress of science and technology, and also knows the great role of mathematics in many social fields such as military and administrative management, so he wants to guide and influence the people around him, forcing them to get rid of the behavior that has little practical significance, and put their minds on the real national economy and people's livelihood.

Liu He not only had to influence scholars like Li Yan, Liu Fang and Xu Miao, but he also had to force generals such as Zhao Yun, Sun Li, and Xiahou Lan to also learn some knowledge of arithmetic.

Why do you want generals to learn mathematics too? Because in this era, when the two armies are fighting, they have to arrange their troops, so it involves the issue of optimizing the allocation of troops and the arrangement of formations.

How to optimize the allocation ratio of cavalry, halberds, spearmen, swordsmen, archers, crossbowmen and other troops? It relies on repeated statistical comparisons and careful scientific number crunching!

How to deduce and set up the conical array, the sharp arrow array, the goose walking array, the serpentine array, the square array, the circle array, and the gossip array? Rely on the operation of all kinds of geometric figures!
