Sun Quan sent an emissary to Liu Bei, intending to attack Liu Zhang in Yizhou. As a result, Liu Bei had his own plans for Yizhou, so he played a trick at this time, persuading Sun Quan to let Liu Zhang go and not attack Yizhou, but he left Guan Yu to guard against Eastern Wu, and then led a large army to attack and take Yizhou into his pocket. When Sun Quan saw that he had been put in a position by Liu Bei, he was extremely angry, and immediately sent an emissary to Liu Bei to ask Liu Bei to return Jingzhou, but after the emissary returned, he brought Liu Bei's reply to Sun Quan: "Wait until Liangzhou is taken, and then return Jingzhou." This can make Sun Quan angry, Sun Quan was also a violent temper, this time it was violent, and in anger, he ordered Lü Meng to be a general and sent him to lead an army of 30,000 to capture the three counties of Lingling, Guiyang and Changsha.
As a result, the two counties of Changsha and Guiyang were annexed, and only Lingling Taishou Haopu insisted on not surrendering. Lü Meng designed to lure Hao Pu out of the city and surround it, and Hao Pu had no choice but to surrender, and in this way, these three counties were taken by Lü Meng's soldiers without bloodshed. Liu Bei was horrified by the news and personally led 50,000 troops from Chengdu back to the public security seat, and at the same time sent Guan Yu to lead an army of 30,000 to retake these three counties.
At the same time, Sun Quan personally led an army from Moling to Lukou, and sent Lu Suxian to lead 10,000 people to garrison Yiyang to confront Guan Yu. Lü Meng, who had successfully captured the three counties, also led an army with Sun Jiao and Pan Zhang to Yiyang to join Lu Su.
For the sake of the overall situation, Lu Su invited Guan Yu to meet him, and proposed that they should arrange their soldiers and horses a hundred steps away, and only the generals would each bring a single knife to the meeting. After Lu Su made his decision, his subordinate generals were afraid of change and advised Lu Su not to take risks easily. Lu Su said in awe and without fear: "At this point, what should be said must be clearly stated." Otherwise, whether Liu Bei is treacherous and betrays us, the right and wrong of this matter is still inconclusive. What can he do to Guan Yu? "After saying that, I resolutely went to the meeting."
After the meeting between the two sides, Lu Su opened the door and rebuked Guan Yu, saying: "At the beginning, we jointly resisted Cao Cao, and the Battle of Chibi defeated Cao Cao, and then because you were defeated, the situation at that time was not even a place to stand, out of the overall situation of joint resistance against Cao, we sincerely lent Jingzhou to you, and now that you have occupied Yizhou, Jingzhou is still unwilling to return, we only need to return to the three counties of the nine counties of Jingxiang, why don't you agree?" Before the words could be heard, a member of Guan Yu's seat stood up and said, "When it comes to land, it lies in the fact that the virtuous live in it, where is a long-term possession?" As soon as Lu Su heard this, his eyes widened, his face changed drastically, and he scolded this general in a loud voice, and the atmosphere suddenly became very tense. So Guan Yu stood up with a knife and said to Lu Su, "This is a major affair of the country, and he knows something." At the same time, the eyes made the general retreat.
This is the famous single knife to the meeting, it can be seen that the single knife to the meeting is not only Guan Yu alone, but all the generals attending the meeting, including Lu Su, in addition, Guan Yu's general is determined not to be Zhou Cang, because Zhou Cang is a fictional character in the "Romance of the Three Kingdoms", as for who this member will be, there is no clear record in the historical records.
The single knife meeting was inconclusive, the two sides were still sword-fighting, deadlocked, and war was about to break out. Just at this moment, news came from the north, Cao Cao took advantage of the confrontation between the two of them to lead a large army to attack Hanzhong, Hanzhong can be said to be the gateway to Yizhou, and where is Zhang Luna, who occupies Hanzhong, Cao Cao's opponent? Therefore, as soon as Liu Bei heard this news, his heart was tugged, and he was worried that cao jun would directly threaten Yizhou, which had just arrived, and hurriedly sent people to make peace with Sun Quan. Sun Quan also learned of this news, and felt that the garrison of the Northern Cao Army at this time must be empty, and instead of stalemated with Liu Bei, it was better to take advantage of the opportunity to go north and seize Cao Cao's territory. Therefore, the two sides quickly agreed that with Xiangshui as the boundary, The east and west would divide Jingzhou equally. That is to say, the three counties of Jiangxia, Changsha and Guiyang belonged to Sun Quan, and the three counties of Nan County, Wuling and Lingling belonged to Liu Bei. The Sun and Liu families truced and called off the war. Historically known as "Xiangshui Demarcation"
At that time, Lu Su and others believed that Cao Cao was dominating the north, the war had just begun, and the two families of Sun and Liu should rely on each other, help each other, and hate each other, and should not affect the overall situation because of the competition for interests between the two sides. However, Lü Meng held a different opinion, and he secretly offered a plan to Sun Quan, saying: "If the general Sun Jiao is now allowed to defend Nan County, Pan Zhang will enter the White Emperor City, and Jiang Qin will lead a mobile army of 10,000 people to patrol up and down the Yangtze River, and the enemy will go wherever it appears, while Wei Chen and I will attack Xiangyang to the north for the lord." Arranged like this, what else are you worried about Cao Cao? Where else do you need to rely on Guan Yu? Besides, Guan Yu and their vassals, relying on their cunning and strength, are capricious everywhere, how can they really regard them as allies! The reason why Guan Yu did not immediately invade our territorial jurisdiction to the east is that you are extremely holy, and we generals are still alive. If we don't beat them up when we're strong now, once we're gone, is it possible to exert our strength then? Although Sun Quan thought that Lü Meng's proposal was reasonable, the time was not yet right, especially at this time, which was a good opportunity for Cao Cao's virtual expedition, so he still adopted the ideas of Lu Su and others, maintained Sun Liu's alliance, and changed the strategic plan to attack Hefei from the north.
When it comes to the problem of borrowing Jingzhou, many people, especially orthodox historians, believe that the land is the state, according to the dynasty at that time, it is the Eastern Han Dynasty, after all, the Han XianDi is still in power, Jingzhou should actually be the Han Xiandi, there is no Liu Bei to borrow from Sun Quan, but at that time, in the era of the world's strife and the rise of the masses, the Han family court of the Han XianDi actually did not have any binding force on the powerful side of the divided side, if the Han Xiandi at that time had a little role, it was used by Cao Cao. But then again, who can say that Cao Cao won the victory over the strong with the weak, and the result of the arduous pioneering and final unification of the north was that the Han Xiandi played an important role in it? Even yuan shao attacked Cao Cao from the south according to the four northern states, and did not regard Cao Cao and Emperor Xian of Han as one at all, so after Cao Cao unified the north, who can say that Cao Cao's unified northern land was from the Eastern Han Dynasty?
Since this is the case, Jingzhou is the same, it is actually after the defeat of Cao Cao at the Battle of Chibi, in the face of the still powerful Cao Cao, Sun Liu and the two families under the consideration of joint resistance to Cao Cao, that is to say, when Sun Quan did not lend Jingzhou (loan) to Liu Bei, then the anti-Cao alliance would collapse, Sun Liu would inevitably ignite the flames of war, which would make Cao Cao sit and reap the benefits and eventually dig his own grave. And the four counties of Jingzhou, it is true that after Chibi drove out Cao Cao, and had Jingzhou as a base area, Liu Bei gradually personally pocketed it, which had nothing to do with Sun Quan. And Sun Quan also understands the truth of this very well. Also under the premise that only by uniting against Cao Cao could survive, the final result of the game was that although Liu Bei was somewhat reluctant and Guan Yu was even more arrogant and arrogant not to look at Sun Quan in his eyes, but with the overall situation as the most important, in the end, Liu Bei and Sun Quan divided Jingzhou with Xiangshui as the boundary. These are the results of the game, and both sides have reached the balance of interests.
After that, in the twenty-second year of Jian'an (217), Lu Su died, at that time, only 46 years old, only 10 years longer than Zhou Yushou, which should be said to be in his prime now, it can be seen that in that era, the short life span caused by war was not only reflected in the people of Li, but also the official eunuch class could not live long. In the future, when I introduce each character, I will help you pay attention to this in terms of age. After Lu Su's death, Sun Quan personally held a funeral for him and personally attended the funeral, and his friend Zhuge Liang also personally held a mourning ceremony for him, and the "Romance of the Three Kingdoms" says that Zhuge Liang personally went to Eastern Wu to mourn Zhou Yu, which is not recorded in the "Romance of the Three Kingdoms", and the mourning of Lu Su is clearly recorded. I think it is the result of Zhang Guan Li Dai in the "Romance of the Three Kingdoms".
Later, Sun Quan ascended the throne as emperor in Jiangdong, and the pace of history officially evolved from the Later Han Dynasty to the Three Kingdoms stage, and when he ascended to the altar, Sun Quan turned back and said to the ministers: "In the past, Lu Su often said that the Han Room could not be revived, and I Sun Quan would one day be called emperor, which shows that he is really a person who understands the general trend of the world." ”
When the emperor moved the capital to Jianye, he and the general Xiang Wenwu held a meeting and said to Yan Yu: "I used to compare Lu Zijing to Deng Yu, and at that time your arguments about this did not stop, what do you think now?" Yan Yu bowed down and replied, "I don't understand this meaning, I think it is too much to praise Lu Su." The Emperor said: "When Deng Yu met Emperor Guangwu, when Emperor Guangwu was under Emperor Gengshi, Fu Hebei, and performing the Great Sima Affair, Emperor Guangwu initially did not have the ambition of an emperor, and it was Deng Yu who persuaded him to aspire to restore hanye, and finally achieved the imperial cause." This has to be traced back to the source, in fact, it stems from Deng Yu's suggestion. Zi Jing was proud and clever, and when he first talked to me, he involved the foundation of the emperor. This is similar to Deng Yu, which is why I compare it this way. There's a reason for that, it's not that I prefer him. Yan Yu was then impressed.
When Lu Su died, he had a widow named Lu Shu. After Lu Shu grew up, he successively served as the general of Zhaowu, the Marquis of Duting, the governor of Wuchang, the governor of False Festival, and the governor of Xiakou, he ruled the army strictly and competently, and died of illness in 274 AD, and his son Lu Mu inherited the title and commanded the soldiers and horses.
