After Liu Bei got Yizhou, Sun Quan sent Zhuge Jin to return Jingzhou, and Liu Bei certainly did not agree! But it is not easy to say directly, saying that I have been fighting the idea of Liangzhou for so long, and when I get Liangzhou, I will return all of Jingzhou to Eastern Wu. When Sun Quan heard this news, he was furious and said that Liu Bei didn't want to play Laipi? Immediately sending three Taishou to Changsha, Guiyang, and Lingling Counties to take up their posts, Guan Yucai did not believe Sun Quan's set and blasted out the three Taishou sent by Sun Quan.
Not to be outdone, Sun Quan immediately ordered Lu Su to lead an army of 10,000 to attack Changsha, and Lü Mengluxun to lead an army of 20,000 to attack Guiyang and Lingling. Liu Bei also ordered Guan Yu to lead 30,000 troops to Yiyang and 50,000 troops to the public security, Liu Bei was too unlucky, just arrived at the public security, Cao Cao wanted to fight Hanzhong, Liu Bei went back with his troops, and he wanted to duel with Cao Cao at the peak of Hanzhong. Guan Yu could only be ordered to retake the three counties by force. Sun Quan immediately ordered Lü Mengluxun, who had already conquered Guiyang and Lingling, to immediately lead an army to support Lu Su, and confronted Guan Yu tit-for-tat, and a major battle was about to break out.
Because at this time Lu Su still did not want to destroy the alliance relationship, so during the confrontation between Yiyang and Guan Yu, Guan Yu was invited to go to the meeting with a single knife from the military camp, and Guan Yu also accepted the invitation; during the meeting, Lu Su fell to Guan Yu several times, and Guan Yu's small soldier really couldn't listen to it, saying that the land matter was benevolent and who was who, Lu Su's face changed greatly, it was particularly ugly, and Guan Yu was frightened, and immediately got up and scolded his own small soldiers to go out, saying about the affairs of the country, does anyone know? In the "Biography of Lu Su", Chen Shou's original text is indeed Guan Yu accepted Lu Su's invitation and agreed to attend the meeting with a single knife. However, in Pei Songzhi's note quoting the Book of Wu, Lu Su went to the meeting with Guan Yu single-handedly, and his men also advised him not to go, for fear of being murdered by Guan Yu, Lu Su said that Liu Bei did not know whether he was right or wrong, and Guan Yu did not dare to do anything with him. Although there are differences between Chen Shou's original text and Pei Songzhi's, both sides have participated in the meeting, so I think that no matter how you look at it, the single knife to the meeting does not refer to a single person, but to all the people on both sides who attended the meeting.
