After that, the 18-year-old soldiers in the reserve army that Chutai began to recruit at the end of the second year of the second year were gradually transferred to the Imperial Guards, and the New Wing Battalion was established to participate in the raid against Liu Bei and Cao Cao.

The two armies of Zhenxi and Dingxi in Liangzhou were also often dispatched to enter Yongzhou and immigrate to Xiliang. To put it nicely, they encourage the people to move to Liangzhou, but to put it badly, they were plundering people. Liu Bei was quite angry about this and ordered Xu Huang and Yang Feng to counterattack several times, but they were ineffective.

Therefore, Liu Bei planned to eliminate Cao Cao and control the battle of the Central Plains. Because of Liu Xie's targeted arrangements, it turned into a battle between the three families in the Central Plains. Liu Bei, Liu Xie and Cao Cao invested a total of up to one million troops. Yuan Shu in Huaiyang and Zang Ba in Qingzhou also often sent troops. In addition, Yuan Shao and Liu Bei in the north were still in the war. Gongsun Zan and Liu Yu officially confronted each other in Youzhou. Liu Xie kept sending troops to clear out the salt bandits in Shanyue and Yangzhou. In order to hold Liu Bei's main force into the Central Plains, between Chang'an and Liangzhou, Liu Xie's Zhenxi Army and Dingxi Army also maintained a long-term confrontation with Liu Bei's Chang'an garrison.

Cao Cao remembered Xi Zhicai's words at this time, and felt regretful. He hurriedly asked Chen Jiao to build the Great Wall between Jiuli Mountain and Shiliang Mountain, named it the Jiushi Great Wall. At the same time, he strengthened the city walls of Peicheng, and built the small towns Xiang County, Xiao County and Xiyang County according to the big city. He moved millions of people from Yanzhou and Yuzhou to the south, making Lingbi a big city with more than 300,000 households.

The Jiushi Great Wall was more than 120 miles long. Cao Cao sent troops to fight against Liu Bei while building a city, and there was a shortage of money and food. He borrowed money and food from Liu Xie on the grounds that the people had no food to spend the winter.

Liu Xie knew that he was building the Nine-Stone Great Wall and asked Xi Zhicai. Xi Zhicai said, "If there were no such city, Cao Cao would definitely not be able to defend Xuzhou!"

Liu Xie asked someone to calculate the money needed for construction. When he learned that it would cost 60 million yuan and 28 million stones of food and grass, he asked Cao Cao to exchange it for iron ore. After Cao Cao agreed, he ordered Zhang Zhao to allocate it in six times within three years.

The entire Central Plains ignited a raging war because of Cao Cao's father Cao Song. After the Yellow Turban Uprising and the attack on Dong Zhuo, the entire Han Dynasty fell into a violent shock again.

In this battle between the princes, Liu Xie, the strongest, was determined to wipe out Shanyue in Yangzhou, and Liu Bei, who was not weaker in military strength than Liu Xie, was determined to destroy Cao Cao in his eyes. Therefore, the two tried their best to restrain the outbreak of a large-scale battle between the two sides to avoid affecting their planned plans.

After pacifying Shanyue, Liu Xie was able to join the two states with peace of mind, and then he could have the strength to show up with Liu Bei in the north; after destroying Cao Cao, Liu Bei could get all the Yan and Xu states, and even get involved in Yuqing. A destined showdown was placed in front of the two of them like fate, and they were both preparing for the arrival of that day.

In the autumn of the fourth year of Chutai, Cao Cao sent Man Chong to Xiangyang again, hoping that Liu Xie would send troops to Luoyang. Cao Cao gave the condition to give up Xuzhou to Liu Xie. In order to prevent Liu Bei from seizing the Central Plains, the Taiwan Strait and the Taiwan Command agreed with this suggestion.

Liu Xie decisively denied it. He said to Man Chong: "There is something in the world today because of Cao Cao, how can we cooperate with him? I am the King of Chu of Han, how can I attack the emperor's land in the north!"

When Man Chong resigned, Liu Xie said to the ministers: "Liu Bei is good at employed people, and Cao Cao is also good at utilizing people. However, Liu Bei is good at perseverance and Cao Cao is good at attacking. If Liu Bei gains power, his perseverance will be lost. On the contrary, if Cao Cao gains power, it will be difficult for Chu to have peace! Moreover, although Liu Bei has the reputation of having all the talents of his ministers, he is actually unable to control the situation. In the long run, he will be subject to important officials. Over time, he will have variables. I can still watch the changes and move. Cao is ten times more capable than Liu Bei. Once he gains power, he will be like a dragon leaping through the sky. It is difficult to control him. Today's opportunity is rare. You should take the opportunity to destroy Cao Cao!"

All the ministers were convinced and praised Liu Xie as a genius, and he knew that his great cause was settled in private!

In Liu Xie's heart, he knew that Cao Cao's ability was far superior to Liu Bei, so when he had no more energy to deal with the north, he would rather Liu Bei sit firmly in the north than see the situation where Cao Cao ruled the north.

During the truce in late autumn, Liu Xie went to Changsha to inspect the wheat cultivation situation in the east and found that the grain plantings of farmers were not consistent. After some good or bad things, Liu Xie immediately asked Zhang Zhao to establish a grain planting department to select the best varieties from various places, and then select them after trial planting in official fields, and then promote them to various places in Chu.

During the construction of Jinling City, the Wu family, a large clan in Jiangdong, established the first Southeast Trading Company that met Liu Xie's requirements on the basis of allocating 50 million yuan in Zhiluotai, and first became the first national businessman in the construction industry. Liu Xie personally selected a number of students who were good at water conservancy projects from Xiangyang Academy to go to the Southeast Trading Company, and gave more than 80% of the projects in Jinling City to the trading company, encouraging the trading company to continue to move forward.

Liu Xie divided scholars into five levels: students, bachelors, scholars, doctors, and great sages according to their knowledge, and divided into six categories: classics, business, law, medicine, literature, and art according to their studies. All of these six categories can be applied for qualifications from each institution. Just like craftsmen are divided into hierarchical schools, scholars at all levels can enjoy the allowance for the hierarchical Taiwan. At the same time, it is strictly stipulated that scholars and craftsmen hired by each trading company should pay corresponding salary according to the hierarchical regulations.

Since business courses were implemented in Chu for many years, the status of merchants has also been greatly improved due to the existence of state-owned businessmen. Most people did not oppose setting people who were proficient in business courses among scholars, but the first time the medical class was raised to such a high level, it still aroused the opposition of most scholars.

Liu Xie's first reaction was not to compromise, but to directly sign Zhang Ji as the Marquis of Jing'an Ting to show his achievements in treating the people. At the same time, it was stipulated that students who were good at medical skills should be given priority to recruiting Xiangyang Academy. This move caught many people off guard. Zhang Ji's contribution was obvious. He once treated Emperor Ling of Han. When the plague occurred in the south, he led a group of doctors to the south to treat the people and curb the spread of typhoid fever. It can be said that more than 10,000 people were saved in his hands, but it was still surprising, even incomprehensible.

Through this award, Liu Xie cleverly shifted people's attention to the role of doctors, which greatly alleviated the scholar's indifference and resistance to doctors and also improved the status of doctors. Since then, the number of scholars who are willing to study medicine in Chu has gradually increased.

This alone is not enough. Liu Xie expanded the Xiangyang Academy and separated the bachelor's degree. He set up Xiangyang Economic College, Xiangyang Business College, Xiangyang Law College, Xiangyang Medical College, Xiangyang Arts College and Xiangyang Arts College in the Xiangyang Academy. At the same time, the newly established Jiangnan Academy was transformed according to the same system, which stipulated that the first-teacher officials of each college must have doctoral qualifications and their position is priest wine, while the former priest wine Guan Ning promoted it to the general priest.

Guan Ning expressed resistance to Liu Xie's continuous restructuring and wrote a letter to only serve as the priest of Xiangyang Economic College, which made Liu Xie stumped, so he had to ask Huang Chengyan to come out of the mountain to serve as the general priest.

After dealing with these matters, Liu Xie did not stop. He continued to raise Ma Jun, Bai Yi, Zheng Hun and others to establish Xiangyang Institute of Technology to train craftsmen, and put the right to define the craftsmen level that originally belonged to the military platform into the hands of Xiangyang Institute of Technology, allowing Bai Yi to serve as a sacrificial wine. In order to prevent the scholars from experiencing conflicts, Liu Xie did not include the institute in Xiangyang Institute of Technology, but like the Xiangyang Institute of Technology, he designated a single institution. At the same time, he transferred special courses such as farming, water conservancy, civil engineering, and alchemy that the scholars were more disgusted with.

When dealing with the issue of alchemy, Liu Xie first did it to catch the alchemists who gathered in Xiangyang to sell alchemy medicine, scolded them fiercely, and then deliberately arranged for famous doctors such as Zhang Ji to refute these alchemists, and finally let the alchemists form a new alchemist system according to their own wishes.

Alchemy is a boring thing, and Liu Xie is unwilling to include these people in the Xiangyang Institute of Technology, but after all, they are the ancestors of Chinese chemistry, so they can only slowly guide them. After they can communicate with Rome in the future, they can absorb the knowledge systems of Rome such as mathematics, physics, chemistry, architecture, etc. to change the current system.

At this time, Liu Xie tried his best to develop a strategy of balanced and focused development in all aspects in academic adjustments. He knew that it would be unrealistic to directly introduce a scientific system of future generations. He could only find ways to promote the early dialogue between the East and the West, absorb the advantages of the Western scientific system, influence the current domestic knowledge system, and slowly integrate it in the future.

In order to accelerate this process, before the Hailou Ship was fully trial-produced, Liu Xie asked Zhiluotai and major trading companies to start to detect overseas, mainly to formulate maps. At the same time, Liu Xie also arranged for Xiangyang Institute of Technology to discuss and research on navigation projects. He also provided many ideas for new design and transformation of navigation vessels and tools. For example, in the selection of clocks, he proposed two ideas for pendulum clock timing and hourglass timing, so that the staff of the Institute of Technology could test them themselves.

Liu Xie also arranged the cultivation of new grain seeds to the Institute of Technology to guide the Institute of Technology to register and study plants and animals of the Han Dynasty. Although they did not expect them to discover evolution, it was a good thing to be able to form a more systematic botany and zoology, at least it could have a positive impact on the current agriculture and animal husbandry.

Liu Xie had a very obvious idea in these things. He did not want to directly instill the knowledge he learned in later generations, but established a system and a convention so that they could discover it themselves in this pattern.

Of course, he did not intend to popularize education. Now the Han Dynasty does not need a large number of intellectuals, but what they need is the army and merchants. Promoting economic development does require the strength of the people, but allowing the people to master a lot of knowledge does not give them strength, but rather makes them confused. According to the basic principles of economics, developing productivity and moderately promoting the renewal of superstructure is the king.
