After Yuan Shu became independent, Sun Ce severed relations with him, and the Xuchang court ordered Sun Ce to crusade against Yuan Shu with Lu Bu and Chen Yu, Sun Ce led the army to converge, but found that Chen Yu was secretly plotting to unite with Yan Baihu and others to seize his own territory, Sun Ce was furious, and turned to crusade against Chen Yu and eliminated Yan Baihu, and the first joint crusade against Yuan Shu ended like this.

【Joint Felling】

In the second year of Jian'an (197), Yuan Shu was determined to stand on his own, but Sun Ce was opposed to this, and asked Zhang Hong to write a letter to advise Yuan Shu, but unfortunately Yuan Shu did not listen at all, so Sun Ce broke with him.

After breaking away from Yuan Shu, Sun Ce began to seek the support of the Xuchang court, thus gaining the approval of the Son of Heaven. In the summer of that year, the imperial court sent Wang Pu, a councillor, to Sun Ce to order a crusade against Yuan Shu, and Sun Ce obeyed the order.

According to the record of "Jiangbiao Biography", Wang Pu first promoted Sun Ce to an official, and Shuyun: "Dong Zhuo rebelled against chaos and harmed the country and the people. The first general insisted on the peace discussion, the elegance attempted, and the beauty was heard. Follow the good way, and ask for blessings and never return. Now he is the captain of the cavalry, and he is the Marquis of Wucheng, and he understands the Ji Taishou. ”

Then he gave Sun Ce an order to crusade against Yuan Shu: "Therefore, Yuan Shu, the general of the left, ignored the court, sat on the fierce rebellion, created hypocrisy, and wanted to deceive the people because of the rebellion. It is determined that the general of Pingdong will lead Xuzhou Mu Wen Hou Bu to confuse the demons and the devils, and know the nature of the owl, so he has no way, repairs the palace, sets up the minister, worships the suburbs, and cruels the people, which is a deep disaster. The policy before and after the cloth is the heart of the dynasty, and I want to return the technique, for the national effect, and beg to show the difference. Fu County rewards merit, but diligence is with, so it is favored, inherited the former Yi, heavy to the county, glory and glory, is the autumn of the loss of life. He was eager to fight with Chen Yu, the general of Bu and Xingwu County, and went to discuss at the same time. ”

At that time, Sun Ce thought that the position of cavalry lieutenant was too small and hoped to get the position of a general, so he sent someone to reveal his intentions to Wang Pu. Wang Pu immediately announced in the name of the emperor that Sun Cequan would act as the general of the Ming and Han dynasties.

In order to discuss with Lu Bu and Chen Yu how to deal with Yuan Shu, Sun Ce led his troops to set off.

【Defeat and Extinction】

Sun Ce is dedicated to the country, but some villains are secretly plotting against him.

At that time, Chen Yu was stationed in Haixi, and after learning of Sun Ce's actions, he not only did not cooperate with Sun Ce to fight against Yuan Shu, but secretly plotted to seize Sun Ce's territory.

Chen Yu is Chen Deng's uncle, and it is recorded in many sources that he was once appointed by Yuan Shu as the assassin of Yangzhou, and later betrayed Yuan Shu and was driven out by him, and was later appointed by the imperial court as General Anton and concurrently served as the Taishou of Wu County. In other words, Chen Yu has a fundamental conflict with Sun Ce in terms of sphere of influence, so it is natural that he will take the opportunity to seek Sun Ce's territory.

According to the "Biography of Jiangbiao", Chen Yu sent Duwei Wanyan and others to conspire to cross the river, and held more than 30 seals to the bandits in Danyang, Xuancheng, Jing, Lingyang, Shi'an, Yi, Shezhu and other counties, including Zulang, Jiao Ji and Yan Baihu of Wucheng in Wujun, so that they could serve as their own internal response, and prepare to seize Sun Ce's territory when Sun Ce sent his troops. After Sun Ce arrived in Qiantang, he found out about this matter, so he sent Lu Fan and Xu Yi to attack Chen Yu in Haixi, breaking his army, and his general Chen Mu was beheaded, and more than 4,000 family members of officials under his command were captured.

According to the "Shanyang Gongji", Chen Yu finally managed to escape, and rode to Jizhou alone, attached to Yuan Shao, and was appointed by Yuan Shao as the former commander of Andu.

And the crusade against Yuan Shu was finally over.

But Sun Ce did not stop attacking because of this, he completely swept Wu Jun, defeated Yan Baihu, and stabilized his rear.

Yan Baihu occupied the mountain as the king, and Wu Jing and others were ready to crusade against him earlier, but Sun Ce thought that Yan Baihu was not enough to worry about so he went ahead to crusade against Huiji, and at this time Yan Baihu colluded with Chen Yu, and Sun Ce couldn't bear it anymore.

In the "Wu Lu", there is a detailed record of Sun Ce's pacification of the thieves of Wu County.

At that time, in addition to Yan Baihu, Wu County also had Wucheng Zou He, Qian Tong and the former Hepu Taishou Jiaxing Wang Sheng, all of whom gathered tens of thousands of people to occupy one side, Sun Ce sent troops to fight, all of which were broken, except for Wang Sheng because he had an old relationship with Sun Ce's father Sun Jian, and at the same time was let go by Sun Ce by Sun Ce's mother Wu's intercession, everyone else was basically wiped out by Sun Ce.

Later, Sun Ce personally crusaded against Yan Baihu, Yan Baihu was the biggest thief in Wu County at that time, and even got the refuge of Xu Gong, the former Taishou of Wu County, which was not a small force.

At that time, Sun Ce first sent Wu Jing out to defeat Yan Baihu, and then surrounded Yan Baihu, Yan Baihu saw that the situation was unfavorable and sent his younger brother Yan Yu to sue for peace.

When Yan Yu and Sun Ce met, Sun Ce slashed at the seat with a sharp blade, and Yan Yu's body shook when he saw it. Sun Ce smiled and said to Yan Yu: "I heard that you can sit and jump and be agile, so I'm just joking with you." Yan Yu replied, "As soon as I see the blade, I will become like this. Sun Ce heard his words and knew that he was actually very incompetent, so he immediately killed Yan Yu with his halberd. Yan Baihu and the others were very frightened when they heard that Yan Yu, who was famous for his bravery, was killed by Sun Ce.

Yan Baihu couldn't resist, and went to Yuhang with Xu Gong to fight against Xu Zhao. Cheng Pu asked Sun Ce to launch an attack, and Sun Ce said, "Xu Zhao is righteous to the old monarch (referring to Sheng Xian), sincere to his old friend (referring to Yan Baihu), and this husband's ambition is also", so he gave up the attack.

Yan Baihu has not been recorded since then, and he has withdrawn from the stage of history.

【Waihe Imperial Court】

After Sun Ce became independent of Yuan Shu, his external environment was not good, the princes of Jiangdong regarded him as an enemy, the north was the old lord Yuan Shu who had itchy teeth that he hated, and Liu Biao in the west was Liu Biao, who had a grudge against him for killing his father, and the surrounding forces also regarded themselves as dangers, so this Sun Ce urgently needed a strong foreign aid.

And this foreign aid is naturally best Cao Cao, oh no, it is the Son of Heaven, and it is the Xuchang court that occupies the righteousness.

Therefore, Sun Ce has been courting the imperial court after independence, and even obeyed the orders of the imperial court to crusade against Yuan Shu, according to the "Jiangbiao Biography" record, in the third year of Jian'an (198) Sun Ce again sent envoys to pay tribute to the imperial court, the gift was double that of the first year of Jian'an, and in this year, the imperial court promoted Sun Ce to a rebellious general and renamed him the Marquis of Wu.

A year later, Sun Ce also sent Zhang Hong to Xuchang to make friends with the ministers of the court and China, and publicized Sun Ce's exploits in Jiangdong to show his loyalty to the Han family.

Of course, Cao Cao would give Sun Ce a word Hou not only because of Sun Ce's kindness, but later Liu Zhang also posted Cao Cao upside down, and I didn't see Cao Cao being so good to Liu Zhang, mainly because Cao Cao also needed Sun Ce's support at that time. At that time, although Cao Cao controlled the Son of Heaven, the external environment was also very poor, taking the south as an example, the imperial court could not reach it at that time, and Yuan Shu and Liu Biao also had a very poor relationship with Cao Cao, so Cao Cao also needed a strong chess piece in the south. Under these circumstances, Cao Cao and Sun Ce naturally formed a strong alliance, and although they did not have a clear alliance, they at least had watched over each other for this time.
