After reading history, Cao Cao would naturally not make the same mistake as he did in history, and was burnt to the ground by an east wind.
But all the results in the world are not just accidental.
There are actually three main reasons why Cao Cao was defeated in Chibi.
One was that he was too careless, and the other was that the navy was not strong enough.
The last and most important reason is that Jiangnan is on the rise under Sun Ce's governance.
After absorbing a large number of refugees from the north, Sun Ce reclaimed most of the fertile fields in the south of the Yangtze River, cleared away the barbarians who often made trouble on the border, and used advanced sea ships to obtain many excellent crop seeds from Southeast Asia, Yizhou and other places.
If Cao Cao had not unified the north in time, then Sun Ce would have even had the strength to launch an expedition to the north and unify the country a few years later.
You must know that in the original history of the Three Kingdoms, the Western Jin Dynasty was able to destroy Soochow because Sun Hao, the monarch of Soochow at that time, was too cruel and stupid: not only did Soochow people panic, but he also abolished the construction on both sides of the Yangtze River. defense facilities.
Therefore, when Cao Cao was not much stronger than the later Western Jin Dynasty, it was extremely difficult to defeat Liu Bei, who had the secret recipe for gunpowder, and Sun Ce, who had stabilized Jiangnan.
The two sides persisted in Chibi for several months, but Cao Cao was still unable to find a chance to defeat the Sun and Liu coalition.
Finally, after news of the rebellion of the Xiongnu Kou Bian and Xiliang came from the north, he had no choice but to burn the warships and withdraw his troops.
Cao Cao was not defeated in Chibi this time, so he did not rush back when he retreated, giving Liu Bei and Sun Ce no chance to pursue him.
However, after Cao Cao's army left, Liu Bei still led his army to capture most of the land in Jingzhou.
He also followed history and took advantage of Liu Zhang's fear of Zhang Lu to lead his army to capture Yizhou.
Liu Bei followed his old path of separatizing Western Shu.
In addition to stabilizing his rule in Jiangnan, Sun Ce also sent a large number of trading fleets to sea.
With the help of the nautical chart copied from Xunze, he successfully communicated with the people at that time.
Countries such as the Kushan Empire, the Persian Empire, and the Roman Empire in ancient India established contacts and started trade.
After his death, he did not pass the position of monarch to Sun Quan, but to his son.
But it is a pity that, as Sun Ce's younger brother, Sun Quan's authority in Soochow is second only to Sun Ce.
Although he promised Sun Ce to assist his son when Sun Ce was seriously ill.
But only two years later, Sun Quan successfully seized power on the pretext that Sun Ce's son was immoral.
After Sun Quan took control of Soochow, history returned to its old state.
The Sun-Liu alliance collapsed on its own.
Even if Sun Ce married Sun Shangxiang to Liu Bei during the Battle of Chibi, he could not stop Sun Quan from coveting Jingzhou.
So when Guan Yu tried to take back all the land in Jingzhou from Cao Cao, Soochow attacked Guan Yu from behind, but Lu Meng still crossed the river in white clothes, and trapped Guan Yu in Maicheng with Cao Cao, and finally died.
After Guan Yu's death, although Liu Bei knew that his crusade against Soochow was likely to fail, he still raised troops to attack Wu for revenge.
Then because of Lu Xun's genius tactics, the battle went badly, and he retreated in embarrassment, leaving Zhuge Liang in Baidi City.
According to historical records, Liu Bei asked Zhuge Liang to recuperate and not attack Wei after his death.
However, after Zhuge Liang had managed the Shu Han for several years, he still launched many northern expeditions to the Central Plains.
But it still failed.
It is worth mentioning that Liu Bei did not proclaim himself emperor this time, so later generations called him King Zhaolie of Han instead of Emperor Zhaolie of Han.
The reason Liu Bei did not proclaim himself emperor was naturally Cao Cao's series of efforts to change history.
The knowledge Cao Cao learned in modern times mainly included scientific farming and the constitutional monarchy.
Among them, scientific farming methods helped Cao Cao quickly restore food output that had been affected by the war.
For ancient people, food always came first.
Whether it is to appease the people or march to war, food is indispensable.
With enough food, Cao Cao wiped out Yuan Shao's remaining forces after the Battle of Guandu faster than ever before.
And he also unified the north a year early.
After the north was consolidated, the first thing Cao Cao did was to find a reason to destroy the Sima family and watched Sima Yi be executed with his own eyes.
Although the destruction of the Sima family gave Cao Cao another black spot, there were already many black spots on Cao Cao's body, and it wouldn't hurt to have one more.
The purpose of destroying the Sima family was to protect Cao Wei's future, and how to deal with Emperor Xian of the Han Dynasty was related to Cao Wei's present.
As early as when Cao Cao was still studying librarianship at Xunze, he studied the constitutional monarchy no less than dozens of times.
So after he returned to the Han Dynasty, he established a constitutional monarchy system with Cao Wei characteristics to ensure the legitimacy of his rule.
Historically, Cao Cao's constitutional monarchy system has been highly praised.

If you search on Xunze, you can find articles that evaluate the historical impact of the constitutional monarchy system founded by Cao Cao.
The reason why the constitutional monarchy system founded by Cao Cao is called a characteristic constitutional monarchy system is because this system was established entirely to ensure the legitimacy of the Cao family's governance in the Han Dynasty, and was not to restrict imperial power.
First of all, Cao Cao deified Liu Bang into the son of Haotian sent to the world.
He was the son of God who descended to earth to end the rule of the violent Qin Dynasty.
Therefore, the Liu family has the blood of Haotian flowing in them, and they are sons of Heaven that are different from ordinary people.
But because the human world is too filthy, the Son of Heaven will become a tyrant after staying in the human world for a long time.
Therefore, when Haotian saw that the sons of heaven left by Liu Bang were gradually becoming cruel, he once again sent his other son Liu Xiu and his boy Wang Mang to save the big man.
But since Liu Xiu is also a son of heaven, his descendants will also be contaminated by the evil of mortals.
So after Haotian discovered this situation, he sent another boy under his command, Cao Cao, to save the Han and at the same time be responsible for purifying the Son of Heaven.
After publicizing it and letting everyone know about it, Cao Cao built a tall palace in Xuchang and named it Tianzhi Palace.
The function of this palace is to purify those polluted sons of heaven, and Han Xian Emperor Liu Xie was naturally sent here by Cao Cao, and could only meet with outsiders at a fixed time every day.
The Son of Heaven has been imprisoned and purified, so the government will need someone to take care of it.
So Cao Cao, as the boy under the throne of Haotian, stipulated that the Cao family, as the descendant family of the boy under the throne of Haotian, had the qualifications to manage the country on behalf of the Son of Heaven.
The Son of Heaven needs to reproduce for a hundred generations before he can purify himself of the bad habits of the world.
Therefore, the Cao family needs to rule for a hundred generations in place of the Son of Heaven, and has established relevant contracts and laws.
It is stipulated that the emperor, as the representative of the country, can only attend various occasions as a symbol of the country before the purification is completed, and has no actual rights.
As the actual rulers of the country, the Cao family will return power to the Liu family after Liu Xie has reproduced for a hundred generations.
If the Cao family does not return power after Liu Xie has reproduced for a hundred generations, then the whole world will attack him
