In 198, Lu Su was sitting idly at home when he was suddenly surrounded by hundreds of strong men. The leader was a beautiful man, who said that his name was Zhou Yu and he wanted to "borrow" some grain from Lu Su! Lu Su calmed down, pointed to a granary and said, "There are 3,000 huo in it, you can take it at will!" Zhou Yu was shocked, and said in his heart that he was not afraid of so many bullies against us, and he was certainly not an ordinary person, so he took the initiative to make friends with him.
Soon after, in order to avoid Yuan Shu's entanglement, Lu Su went to Juchao and defected to Zhou Yu, and through him he became acquainted with Sun Ce. But Lu Su didn't seem to have any good feelings for Sun Ce, but instead wanted to join a small warlord named Zheng Bao. Zhou Yu expressed strong opposition, and in order to make Lu Su die, he took it upon himself to "pick up" the mother of the family to Wu County, and Lu Su could only go with him. After Sun Ce's death, he became an aide to Sun Quan.
Once, during a drink, Sun Quan told Lu Su that he wanted to become the Duke of Qi Huan in the chaotic world, but Lu Su told him: "In my opinion, the Han Dynasty has been saved, and Cao Cao is not easy to kill." It is better to take advantage of the fact that the crowd has no time to look south, eliminate Huang Zu, attack Liu Biao, occupy the south of the Yangtze River, and achieve some imperial achievements! ”
Sun Quan listened very coolly, but still held it, pretending not to understand what Lu Su was talking about. But privately, he was not good to Lu Su, and often rewarded him with money and grain. When Lu Su was attacked by Zhang Zhao and others, Sun Quan also had a lot of protection for him.
In 208, Sun Quan broke through Xia Kou and beheaded Huang Zu, and then attacked Liu Biao, who was seriously ill in Jingzhou. Cao Cao did not want to march south so quickly, but he was so stimulated by him that he immediately gathered a large army in Nanyang and prepared to attack Liu Biao.
When Lu Su heard this, he immediately addressed Sun Quan: "Liu Biaoxin died, but his two sons were not harmonious, if Liu Bei can get these two juniors and let them work together, we should ally with them to resist Cao Cao; if they are separated from Germany, we will make other plans." Now I will first go to Jingzhou to explore the truth, otherwise I will be chased ahead by Cao Cao! Sun Quan immediately approved.
However, when Lu Su first reached Nan Commandery, Liu Chun had already surrendered to Cao Cao. Lu Su rushed to Changsaka in Dangyang again, and finally met Uncle Liu Huang, who had fled south. Liu Bei was about to go to Cangwu taishou Wu ju, but Lu Su praised Sun Quan like a flower and persuaded him to join forces with Jiangdong to fight against Cao. Liu Bei was moved and sent Zhuge Liang to accompany Lu Su to Chaisang to meet Sun Quan.
At that time, the situation in Eastern Wu was indeed not optimistic, because Cao Cao had already issued a war book and wanted to "hunt Wu" with Sun Quan. Due to the disparity in strength, the surrender faction in Sun Quan's shogunate had the upper hand, and Zhang Zhao was one of them. One day at the meeting, Sun Quan was angry with the surrender faction, and got up and went into the toilet. Lu Su quickly chased after him, and Sun Quan grabbed his hand and said, "What does Sir have to say?" ”
Lu Su replied, "Those people are too selfish, and the lord must not listen to them." You think, if I Lu Su had thrown down, there would still be an official doing both sizes, and it would not be a problem to eat and wait for a lifetime. But what about you, sir? Are you willing to give up your father's and brother's inheritance and become a prisoner of jade food for a lifetime? Of course, Sun Quan was not happy, he just had to fight to the death!
Therefore, under the continuous stimulation of Liu Bei's joining, Zhou Yu, Lu Su, and Zhuge Liang, Sun Zhong plotted to defy the public opinion and vowed to fight Cao Cao to the end! It may be that God was also touched by him, and under the condition of extremely tight troops, Sun Liu's coalition army actually broke Cao Cao in Chibi!
After the war, Sun Quan's trust in Lu Su was incomparable, calling him "I let his Deng Yu". Before Zhou Yu's death, he recommended Lu Su to guard Jiangling instead of himself, and gave Lu Su the four thousand private soldiers and four counties in his hands, making him the second most famous person in Eastern Wu. But soon, the Sun Liu alliance that Lu Su had vigorously promoted was on the verge of collapse.
After driving Cao Cao away, Sun Quan started the idea of Yizhou and asked Liu Bei about his attitude. Liu Bei said that he and Liu Zhang were brothers of the same sect, and could not bear to see him being conquered by wu troops, and pleaded with Sun Quan to give up, otherwise he would wear a cloak and scatter the guiyin mountain forest.
But soon after Sun Quan agreed, Liu Bei preemptively stepped into Shu and took Yizhou! Sun Quan scolded Liu Bei for being a "cunning prisoner" who dared to calculate himself, and then immediately asked him to return Jingzhou. Liu Bei said on his lips: "When I take Liangzhou, I will return Jingzhou", but what I thought in my heart was: Why should I return the land I snatched by my ability? “
Sun Quan was furious and immediately sent Lü Meng to attack Changsha and Guiyang and force Lingling. Liu Bei heard of the change, personally led a 50,000-strong army to sit in the public security, and ordered Guan Yu to retake the lost land. Sun Quan also moved to Lukou and sent Lu Sutun to defend Yiyang against Guan Yu.
In order to save the faltering Sun Liu alliance, Lu Su invited Guan Yu to meet and negotiate. And proposed: the two bosses arranged the team a hundred steps away, and the generals attending the meeting were only allowed to carry a single knife. Guan Yu ranzhi.
At the meeting, Lu Su made a severe criticism of Guan Gong, saying: "When you defeated the soldiers and came to vote, the lord of my family could not bear to let Liu Huang's uncle eat and sleep, so he lent Jingzhou to you. We took a step back and only asked you to return the three counties, but you still didn't buy it. ”
As soon as Lu Su finished speaking, one of the military generals beside Guan Yu suddenly shouted, "The land under heaven, the benevolent ones have learned that when it comes to land, how can you occupy it for your Sun family!" Lu Su was furious: "I talk to your boss, who told you to interject!" Guan Yu's face could not be stopped, and he also reprimanded: "This is a major national event, you know what, you can't go down!" ”
However, although Lu Su's mouth was hanging in the river, the meeting did not come up with any results, and neither side refused to give in, and war was about to break out. At the critical moment, Cao Cao suddenly attacked Hanzhong, and Liu Bei, fearing that he would be attacked by the enemy in his belly and back, urgently sent someone to make peace with Sun Quan. The two sides decided to divide Jingzhou equally with Xiangshui as the boundary: Jiangxia, Changsha, and Guiyang to Sun Quan, and NanJun, Wuling, and Lingling to Liu Bei. The two sides boycotted the troops, and history called it "Xiangshui Demarcation".
Afterwards, Lü Meng still wanted to eliminate Xiang Yu. However, Lu Su believed that at the moment when the great enemy Cao Cao was great, the two families of Sun and Liu should hate each other together, and they must not spoil the overall situation because of small profits. After summing up for a while, Sun Quan finally adopted Lu Su's suggestion, but did not deny Lü Meng's claim. This laid the groundwork for the future attack and killing of Guan Yu.
In 217, Lu Su died of illness at the age of 46. Sun Quan was overwhelmed with grief and personally held the funeral and personally attended his funeral. After Zhuge Liang heard about it, he also mourned for him in Yizhou.
