After Sun Quan ascended to the throne, there were many soldiers who disobeyed him, and some people did not have confidence in him, but Sun Quan finally succeeded in gaining a firm foothold through his own practical actions.

【Li Shu's Rebellion】

At the beginning of Sun Quan's succession, his authority was not established, and the Jiangdong group originally controlled six counties in Yangzhou, including Yuzhang, Wujun, Huiji, Luling, Lujiang and Danyang.

On the one hand, Li Shu refused to obey Sun Quan, and also sheltered the traitors of Sun Quan's subordinates. Sun Quan wrote a letter asking him to hand over these traitors to himself, but Li Shu replied and refused, directly saying that if you Sun Quan has virtue, I will naturally submit to you, if you don't, of course I will rebel, don't say anything superfluous. After reading it, Sun Quan was extremely angry and made up his mind to eliminate Li Shu.

However, Lujiang County and Cao Cao's territory were directly connected, so Sun Quan wanted to crusade against Li Shu, and Cao Cao had to take into account Cao Cao's reaction, when Cao Cao coerced the Son of Heaven and ordered the princes, and his power was strong, so Sun Quan communicated with Cao Cao in advance.

According to the "Biography of Jiangbiao", Sun Quan reported these situations to Cao Cao at that time, saying: "Yangzhou assassin Shi Yanxiang, which was used by your predecessor, was killed by Li Shu. Li Shu's wanton killing of court officials should be executed as soon as possible. Now that I am sending troops to conscript, Li Shu will definitely use clever words to ask the court for help. You have a heavy responsibility in the world, and your every move will be noticed by the whole country. I ask you to tell the official in charge of the specific matter and stop listening to Li Shu. ”

So Sun Quan marched into Anhui City and besieged Li Shu. Li Shu closed the door and asked Cao Cao for help, but Cao Cao ignored him. Later, when the food in the city ran out, some women even swallowed dirt and stones to satisfy their hunger. After the capture of Anhui City, Sun Quan indulged his soldiers to slaughter the city, cut off Li Shu's head for public display, and moved more than 30,000 of Li Shu's subordinates to his control area.

The rebellion of Li Shu was quelled by Sun Quan, and Lujiang was again controlled by him, and then Sun Quan took Sun He as the Taishou of Lujiang.

【Sun Fu's Trouble】

At that time, in addition to Li Shu, who was far away in Lujiang, even there were many people in the Sun family who thought that Sun Quan was unreliable, and Sun Fu, who was too shou of Luling at that time, was worried that Sun Quan would not be able to keep Jiangdong. But he communicated with Cao Cao in secret, and was later discovered by Sun Quan and directly imprisoned.

According to the "Dictionary", at that time, Sun Fu was worried that Sun Quan was not capable of protecting Jiangdong, so he sent envoys to secretly communicate with Cao Cao while Sun Quan was traveling. As a result, Sun Fu secretly communicated with Cao Cao and was denounced, and after Sun Quan came back, he pretended not to know about it, summoned Sun Fu with Zhang Zhao, and said to Sun Fu: "Why do you call outsiders to come when you say it unpleasantly between brothers?" Sun Fu denied that there was no such thing, and Sun Quan took the letters exchanged between Sun Fu and Cao Cao to Zhang Zhao, and asked Zhang Zhao to show Sun Fu, who was speechless with shame. Sun Quan then killed all of Sun Fu's close ministers, cut down his troops, and exiled him to the east.

【Danyang Rebellion】

In the eighth year of Jian'an (203), Wu Jing, the Taishou of Danyang, died suddenly due to his death, and Sun Yi, the third brother of Sun Quan, led Danyang Taishou as a partial general, at the age of 20.

At the beginning, Sun Quan killed Wu Jun and kept Sheng Xian, and Sheng Xian's former colleagues Xiao Lian Yan and Dai Yuan fled and hid in the mountains. After Sun Yi took office in Danyang, he took Liluo to Concubine Lan as the governor of the capital, and Dai Yuan was the county Cheng, but Sun Yi was killed by them. The two discussed privately: "Sun He is estranged from General Sun Yi, and he still accuses us like this. If the general Sun Quan comes, we will not be able to live. So he killed Sun He and sent people north to welcome Liu Fu, the assassin of Yangzhou, and asked him to send troops to guard Liyang, and they led the people of Danyang to respond. Later, Sun Yi's subordinates Xu Yuan, Sun Gao, Fu Ying and others killed Fei Lan and Dai Yuan, ending the rebellion.

According to the "Wu Calendar", Fei Lan and Dai Yuan were close to Bian Hong, and were reprimanded by Sun Yi several times, so they plotted to rebel. Because Sun Quan went to Jiangxia to guard Huang Zu, they found an opportunity to carry out treacherous schemes. Later, the magistrates of Danyang County met with Sun Yi, Sun Yi ordered his wife Xu to make a banquet for him, Xu said that the hexagram was not good, and there was a murderous hexagram, and persuaded Sun Yi not to make a banquet. And Sun Yi thought that the chief had been here for a long time and should let them leave as soon as possible, so he began to send off guests. Usually Sun Yi will hold a knife when he goes in and out, because he was drunk, so he sent off the guests empty-handed, Bian Hong then killed Sun Yi from behind, everyone in the county was very busy at that time, and no one went to save Sun Yi. Bian Hong fled into the mountains after killing Sun Yi, and was finally captured by the pursuing Xu. Fei Lan and Dai Yuan put the blame for killing Sun Yi on Bian Hong and killed him, but Danyang's sergeant and Sun Quan's sergeant both believed that Fei Lan and Dai Yuan were the culprits, but they were powerless to crusade against them.

After the concubine, he was even more unscrupulous, he entered Sun Yi's mansion, seized the original Sun Yi's concubines and left and right attendants, and was also ready to ask Sun Yi's wife Xu, but Xu said: "Please wait until after I pay tribute to my late husband."

She found Sun Yi's former cronies Tiger General Sun Gao and Fu Ying, and cried to them the truth about Sun Yi's death. After hearing this, Sun Gao and Fu Ying were very moved and angry, and replied to Xu: "I was favored by Fujun (Sun Yi), and the reason why I died immediately was because I thought that death was not beneficial, and I wanted to have a plan, but I didn't think about it, and I didn't dare to tell my wife." Today's events are really what I think about day and night. "Promised to cooperate with the Xu family to kill the traitor and avenge Sun Yi. So, Xu planned and arranged to hide them in his bedroom, and then Fei Lan couldn't wait to marry Xu as his wife at the end of the month, and Xu lured him into the bedroom with his beauty. At this time, Xu shouted: "The two generals haven't come out to kill the thief yet, let alone when!" Sun Gao and Fu Ying, who had been ambushed in advance, rushed out and slashed Fei Lan to death. Then, the Xu clan used the same method to kill Dai Yuan, and sacrificed their heads to Sun Yi's tomb.

After Sun Quan came over, he wiped out all the remaining parties of Concubine Lan and Dai Yuan, and promoted Sun Gao and Fu Ying as the tooth gate, and other meritorious personnel were also given by different parties.

After Sun Ce handed over the military power to Sun Quan, maybe Sun Yi was not convinced, so he won over the concubines and Dai Yuan, who were at odds with Sun Quan because of Sheng Xian's death, and entrusted him with important tasks, and his thoughts were clearly revealed. He may think that Fei Lan, Dai Yuan and himself are like-minded and can help him deal with Sun Quan, but people don't see it that way, in the eyes of others, Sun Yi is Sun Quan's younger brother.

In hindsight, Sun Ce chose Sun Quan as his heir instead of Sun Yi at that time, and he was really wise.
