Military is the most rational science in ancient Chinese studies. Irrationality will kill people and even destroy the country. Legalism is the most rational one among the hundreds of schools of thought, and rationality is so rational that it ignores human nature. Mathematics is the rational foundation of mathematical logic and the only weapon to overcome empiricism. Many things that seem natural often cannot withstand calculations. To establish a rational scientific system, the role of mathematics cannot be ignored.

This is the purpose of Sun Ce hiring Xu Yue with a large sum of money. He calculated the projection curve of the trench machine, which helped Huang Yueying build the trench machine and left Huang Yueying the most direct feeling. Now that she has encountered difficulties in building a sea boat, she naturally wants to ask Xu Yue to help.

If Wood School is an Academy of Engineering, it is time to establish a Academy of Sciences. Not only can it be used to build sea ships and catapults, but also to military forces. In the future, it will rely on mathematical knowledge to navigate when going to sea.

Sun Ce agreed happily and decided to move Xu Yue and others to Jiangdong after the New Year. In addition to teaching students to Zhutang some basic mathematics knowledge, he also recruited more students to study mathematics and cooperate with Cai Yan's research on Western languages ​​to strive to capture all the mathematical achievements of ancient Greece and ancient India, and build Jiangdong into the academic center of the new era, Alexandria in the east, and Jixia Academy in the Sun Empire.

I'm not educated? I'm just low-key.

When Sun Ce thought of the gathering of academics in Jiangdong, he felt a sense of accomplishment. This is a great cause. My journey is the sea of ​​stars, who would be satisfied with the mountains and rivers of the Central Plains? Of course, although the Central Plains is small, you can't waste it.

"Achu, after thirty years of hard work, the world will be peaceful after thirty years. We will travel around the world on the sea boat you made." Sun Ce held Huang Yueying's hand and sighed.

"Thirty years, you're in your fifties."

"Life is not uncommon for a hundred years, and it is only a middle-aged person who is fifty years old."

"Old but not dead..."

"Achu..." Huang Chengyan interrupted Huang Yueying in time and glared at her. Huang Yueying knew that she had made up her words, so she stuck out her tongue and didn't dare to say anything again.

Sun Ce smiled slightly. Isn’t that true? Your father is still here, saying I’m old?

On the other hand, under the guidance of Guo Jia, a few children added Sun Fu. You and I said, and they calculated in a very good way. The Military Planning Office has developed a habit. Even when discussing strategies, they will first calculate the distance, then calculate the strength, food, and supplies of both sides, and then choose the appropriate terrain within a reasonable range to determine the tactics. As the Military Planning Office, Guo Jia is familiar with guiding the military planning to divide the labor and summarize. Now, when teaching these children, they are even more light and easy to understand, both useful and interesting, and they are enjoyable.

As an adult, Sun Fu's reaction was much faster than others, but he knew that this was not the place where he showed his intelligence, so he refused to say it. Even so, he benefited a lot, and he kept nodding and echoing, and was very excited when he heard the enlightenment. Sun Ce saw it and felt a little regretful. If he had given Sun Fu two military plans in time, he might not have been led by the Cai family.

Sun Ce then turned his gaze to Sun Quan again. Sun Quan also heard it very seriously. A pair of blue eyes stared at Guo Jia in a constant turn, his lips twitched, and he recited silently from time to time. Perhaps because he felt Sun Ce's gaze, he was stunned for a moment, turned to look at Sun Ce. Sun Ce smiled, and Sun Quan smiled somewhat restrainedly and turned to continue listening.

After forgetting for more than half a day, we came to a conclusion that sea transportation is the most cost-effective mode of transportation, which can greatly reduce the burden of transportation of supplies. When considering the terrain, whether it is going south or to Youzhou north, it is more reasonable than moving westward. Jiaozhou involves overseas trade, which is a long-term plan, and Youzhou involves supply of war horses, which is a short-term goal.

This is only relative, combat is never simple. Even if it is transported by sea ships and fought thousands of miles, the consumption is still an astronomical figure. According to Guo Jia's calculations, with 30,000 infantry and cavalry, the combat time of one year, nearly 100 building ships need to be requisitioned, with a total consumption of nearly 5 billion. The grain alone requires nearly 3 million stones, which almost half of the existing surplus grain in the five prefectures is transferred.

In other words, this battle can only be won, but not defeated, otherwise it will be severely damaged and the war will not be launched within at least five years. Everything else is easy to say, and grain is the key. Even if the military farm is vigorously promoted, the increase in grain output will still be a certain amount, and it is difficult to achieve leapfrog development in the short term. Once it falls into a deadlock, the economy will be dragged down in less than two or three years. If a hero cannot cut off his arm and stop the loss in time, he will inevitably be exhausted and fished and fall into a vicious cycle.

This is how the Hundred Years of War in the Han and Qiang dragged down the Han Dynasty.

After this lesson, not only Sun Quan, Sun Yi and others knew that the war could not be started lightly, but Sun Ce also roughly understood what Guo Jia meant. Taking Liaodong and moving westward into Yizhou could not be carried out at the same time. Compared with the two, taking Liaodong is more in line with his current interests. He should concentrate all his strength and prepare for the battle in Liaodong. Before that, quickly stabilizing Qingxu was the key. Establishing a combat base in Donglai and cross-sea attack on Liaodong was the most reasonable choice.

In front of these children, Guo Jia only talked about the material issue and did not involve factions. Advance westward is to give Zhou Yu the opportunity to make meritorious contributions, the Jingzhou Group and the Yuzhou Group will be the main force. Going north is to give Shen You and Taishi Ci the opportunity to make meritorious contributions, the Jiangdong Group and the Qingxu Group are the main force. As Sun Ce’s confidant, Guo Jia did not regard himself as the Yuzhou Group, but consciously considered the overall situation and suggested that Sun Ce increase support for the Jiangdong Group.

This is his foundation, and the fundamental one is the brothers and sisters in front of him. Brothers fighting tigers, father and son soldiers, family members, and clans are always the most reliable force. Even if there is a fight between them, it is a conflict within the clan. In the entrepreneurial stage, this only involves personal safety and will not subvert the interests of the entire clan and may change the surname.

If he is not in his position, he will not plan his own politics. Now that Sun Ce has reached this position, he must consider these issues and weigh the pros and cons of them, and cannot rely on his own likes and dislikes.

After the explanation, Guo Jia returned to his seat and let out a long sigh. "General, how did I teach this lesson?"

Sun Ce understood. "Well, I will ask you to enlighten me in a few years when my son grows up."

"Honor is over." Guo Jia laughed.

Sun Ce got up and walked to the grill, took two fish from the boy who was grilling fish, waved his hand, and signaled Sun Quan to follow him. Sun Quan quickly stood up and rushed behind Sun Ce a few steps. Sun Ce gave him a fish, and the two of them ate while walking, slowly came to the riverside, almost finished eating the fish, and threw the fish bones into the river.

"Zhongmou, you're fifteen next year, right?"

"Brother, remember clearly."

"I have been internship in Runan Prefect's Mansion for two years, and Mr. Zhang has a very good impression of you."

Sun Quan was a little nervous and bowed to salute. "I have any shortcomings, so please give me more advice."

"Do you know how many days off you have taken this year and how many times have you hunted? "

Sun Quan shut his mouth and stumbled for a long time. "Brother, Zhang Gong is good at learning and morality. I also know my elder brother's good intentions, but the classics...it's really meaningless."

"The classics are really not interesting. Is hunting interesting? Is it interesting to go out two or three times a month, and more than thirty times a year. I also took a group of half-year-old children to hunt tigers. I would enjoy it even if I hurt people?"

Sun Quan licked his lips and did not dare to argue again. Obviously, Sun Ce was very clear about his every move, and there would be no good result for quibbling.

"Do you know where Bogao is going?"

"I heard from Bo Gao."

"What about you, do you want to follow the literature or the martial arts?"

"I'll follow my elder brother's arrangement."

Sun Ce was a little angry, so he paused for a moment, controlled his emotions before speaking again. "Among the few younger siblings, you and Akuang are more calm. Akuang likes to study and may do academic research in the future. I originally hoped that you could go to politics, but seeing how you are like this, you may not be able to calm down for a while. Forget it, you should join the army first. It is not a bad thing to suffer a little when you are young."

Sun Quan grinned and then held back his excitement. "Thank you, brother."

“Is there any goal?”

"Uh...Brother, I heard from Ahon that you want to invite him to Jiaozhou?"

"You want to go too?"

"If possible, I want to help Ahon."

Sun Ce turned his head, looked at Sun Quan, and raised the corners of his mouth slightly. This kid is indeed born with a dark heart. He had already inquired, and was waiting for this sentence. When it comes to other troops, he could not escape Sun Ce's control. He could only fight with his father Sun Jian. Sun Ce could not control him. In the future, when Sun Jian gets old or has an accident, he will have the opportunity to directly take over Sun Jian's troops and territory. With strength, whether to be independent or surrender depends on his mood.

Sun Ce estimated that even if he forced Sun Quan to follow his article, Sun Quan would ask to follow Sun Jian. This request was impossible for him. No one could cut off the relationship between father and son. Since Sun Jian could plead for Sun Quan, he would sell his face again and bring Sun Quan with him.

That's fine, at least my dad doesn't have to go to Chang'an.

"You are filial and want to help Ah Weng, of course I can't ask for it. Then, prepare, collect more information from Jiaozhou, and do some homework in advance. Although you are martial arts, you can't be the courage of ordinary men. Try to be a brave and resourceful general, and don't let your name down."

"Here, I will definitely live up to my elder brother's expectations and strive to be a general."

Sun Ce turned around and looked at Xu Jie in the distance and smiled. "Zhongmou, do you like Xu Jie?"

Sun Quan was a little embarrassed. "It's just... I have some good feelings, so I can't say I like it."

"I'll tell you something. As far as I know, marriage to a close relative is not good for children. It is either infertile or has a very high chance of mental retardation."

Sun Quan was shocked and didn't say anything for a long time.

"Besides, Xu Jie is not pretty. You are just a little bit of knowledge. When you go to Jiaozhou, you won't think she is beautiful." Sun Ce paused. "I heard that there are many blonde and blue-eyed Hu girls in Jiaozhou, with white skin and jade-like figures, especially when they were sixteen or seventeen years old, they were so beautiful that they were suffocating."

Sun Quan's eyes suddenly lit up and he subconsciously swallowed.
