已经是今非昔比，但是鲁肃并不知道。鲁肃心里面还是不大看得起吕蒙的，只是想到吕蒙现在官职很大，又路过他的防地，不好意思不去看一下，就去看了一下。那么看了一下，吕蒙当时盛情款待了，酒过三巡以后吕蒙就举起酒杯来问：将军接替周帅，与关羽相邻，怎样对付关羽，将军有想法没有？鲁肃因为不是不大看得起吕蒙吗，也懒得跟他啰嗦，说：唉，随机应变吧，到时候看情况吧。吕蒙说：恐怕不行吧，我们和刘备表面上是一家子，实际上关羽是熊虎，这不是个好对付的人，怎么能够不未雨未绸缪呢？现在吕蒙愿意向将军献计，一二三四。说了些什么，不知道，史书上没有记载。但是我们知道鲁肃听了以后大为惊诧，没想到吕蒙会说出这么多的想法和道理来，听着听着这个身子就移过去了。古人我们知道他是席地而坐，听着听着挪过去，挪过去以后摸着吕蒙的背说：子明啊子明啊，真没想到你现在这么有学问。吕蒙说：士别三日，当刮目相看啊。何况请大哥想想关羽是什么人，关羽也是行军打仗手不释卷的啊，他也是当今的一个大英雄，他怎么肯寄人篱下呢？他怎么会不打我们的主意呢？最后的结果是升堂拜母，也就是鲁肃进入吕蒙家的内室见了吕蒙的母亲，意思就是成了兄弟了。
“It’s not what it used to be, but Lu Su didn’t know.”. Lu Su still had a low regard for Lv Meng in his heart. He only thought that Lv Meng was now in a large position and passed his defense area. He was embarrassed not to take a look, so he went to take a look. After three rounds of wine, Lv Meng raised his glass and asked, “General, who will take over from Zhou Shuai and is adjacent to Guan Yu, how to deal with Guan Yu? Do you have any ideas?”? “Lu Su didn’t have much respect for Lv Meng, so he didn’t bother to nag him and said, ‘Oh, let’s play it by ear. Let’s see what happens then.'”. Lv Meng said, “I’m afraid not. We and Liu Bei appear to be a family, but in fact Guan Yu is a bear tiger. This is not a easy person to deal with. How can we not prepare before the rain falls?”? Now Lv Meng is willing to offer advice to the general, one, two, three, four. What did you say? I don’t know. It’s not recorded in the history books. “But we knew that Lu Su was greatly surprised after hearing this, and we didn’t expect Lv Meng to say so many ideas and reasons. As we listened, our body moved away.”. The ancients knew that he was sitting on the ground. Listen and move over. After moving over, touch Lv Meng’s back and say, “Ziming, Ziming, I didn’t expect you to be so knowledgeable now.”. Lv Meng said, “After three days of farewell, you should be impressed.”. Besides, please think about what kind of person Guan Yu is. Guan Yu is also a great hero in the army and wars. How can he rely on others? Why didn’t he come up with our idea? The final result was a promotion to his mother, which meant that Lu Su entered the inner room of Lv Meng’s house and met Lv Meng’s mother, meaning that he became a brother.
但是这两个人朋友归朋友，兄弟归兄弟，他们的政见是不同的。吕蒙虽然提出了很多怎样对付关羽的主张，鲁肃是默记在心，烂在肚子里，既没有说出来，也没有使用，因为鲁肃是主张维护这个孙刘联盟的，他当然不会实施吕蒙的那一套计策。但是到了建安二十二年鲁肃去世了，吕蒙接任了，情况就不一样了。于是吕蒙就向孙权密呈计策，那么吕蒙向孙权说了什么呢？说了三个问题。
第一个问题：对抗曹操是不是一定要依靠关羽？因为这就是鲁肃的主张嘛，说曹操是更凶恶的敌人，为了对付这个更凶恶的敌人，我们对关羽得好一点，得靠着他。吕蒙说，未必，吕蒙说只要主公派某某到什么地方，派某某到什么地方，派某某带着一支部队在江上走来走去，我吕蒙自己到某某地方，足以对抗曹操，不一定要依靠关羽。这是第一点。第二个问题：关羽是否可靠？吕蒙说靠不住。吕蒙说，关羽君臣，实际上就是指刘备、关羽，刘备关羽这一伙人巧取豪夺，反复无常，根本就靠不住，他绝对不是我们的依靠对象，所以关羽是靠不住的。孙权认为很对，但是孙权还有一个问题，于是孙权就和吕蒙说：你看，我们是先打徐州呢，还是先打荆州？吕蒙说，徐州好打，拿下徐州并不成问题，但是守不住。因为徐州这个地方一马平川，是北方的骑兵纵横驰骋的战场，我们拿下了徐州，今天拿下，明天曹操就派人来夺，我们没有个七八万人你别想守住。不如去打荆州，荆州既能够拿下，我们也守得住。孙权说，好。于是定下了这样一个战略目标——拿下荆州。
“But these two people belong to friends and brothers, and their political views are different.”. Although Lu Meng proposed many ideas on how to deal with Guan Yu, Lu Su memorized them by heart and rotted them in his stomach, neither speaking nor using them, because Lu Su advocated maintaining the alliance between Sun and Liu, and of course he would not implement Lu Meng’s tactics. However, in the 22nd year of Jian’an, when Lu Su passed away and Lv Meng took over, the situation was different. So Lv Meng presented a plan to Sun Quanmi. What did Lv Meng say to Sun Quan? Said three questions.
First question: Is it necessary to rely on Guan Yu to confront Cao Cao? “Because this is what Lu Su advocated, saying that Cao Cao is a more vicious enemy. In order to deal with this more vicious enemy, we must be better at Guan Yu and rely on him.”. Lv Meng said, “Not necessarily.” Lv Meng said that as long as the Lord sends so-and-so to any place, sends so-and-so to any place, and sends so-and-so to walk up and down the river with a troop, I, Lv Meng, can go to so-and-so by myself, which is enough to fight Cao Cao, and I don’t have to rely on Guan Yu. This is the first point. Second question: Is Guan Yu reliable? Lv Meng said it was unreliable. Lv Meng said that Guan Yu Junchen actually refers to Liu Bei and Guan Yu. Liu Bei and Guan Yu, a group of people who are capricious and capricious, cannot be relied on at all. He is definitely not our target, so Guan Yu cannot be relied on. Sun Quan thought it was quite right, but Sun Quan still had a problem. So Sun Quan and Lv Meng said, “Do you think we should hit Xuzhou first or Jingzhou first?”? Lv Meng said that Xuzhou is easy to fight, and taking Xuzhou is not a problem, but it cannot be held. “Because Xuzhou is a flat land and a battlefield where cavalry from the north roam freely, we took Xuzhou, today we took it, and tomorrow Cao Cao will send someone to take it. We don’t have seventy or eighty thousand people, you can’t keep it.”. Why don’t we go and fight Jingzhou? Jingzhou can take it and we can defend it. Sun Quan said, OK. So he set such a strategic goal – to win Jingzhou.
＊拿下荆州对于孙权集团来说至关重要，它可以使孙权的势力从江南向长江上游伸展，同时也可以解除上游对孙权的威胁。孙权曾派人屡次索要荆州，刘备拒不归还，而吕蒙的战略正中孙权下怀。那么要想拿下荆州，首先要对付的就是督荆州的关羽，吕蒙怎样对付关羽呢？
那么你要拿下荆州，就要干掉关羽。但是关羽毕竟是三国时代的熊虎之将，英雄豪杰，关羽也不是说拿掉就能拿掉，说干掉就干掉的，这得要有机会。那么这个机会呢，也是说来就来。到了建安二十四年，建安二十四年发生了什么事呢？建安二十四年的正月，刘备的军队到了汉中。看过前面的节目我们知道，刘备这个时候已经有了蜀地，蜀这块地方，又有了汉中，整个益州就全是刘备的了。那么七月份，刘备就在汉中称王，自称“汉中王”。称了汉中王以后，同一个月关羽发兵攻打襄阳和樊城，这就是著名的“襄樊战役”。关羽的这个行动现在看起来是配合了刘备在汉中的胜利，因为七月份刘备在汉中称王，同一个月关羽就攻打襄樊。
“Taking Jingzhou is crucial for Sun Quan Group. It can extend Sun Quan’s power from the south of the Yangtze River to the upper reaches of the Yangtze River, and it can also remove the upstream threat to Sun Quan.”. Sun Quan had sent people to repeatedly demand Jingzhou, but Liu Bei refused to return it, and Lv Meng’s strategy was right for Sun Quan. So if you want to take Jingzhou, the first thing you need to deal with is Guan Yu, who oversees Jingzhou. How does Lv Meng deal with Guan Yu?
So if you want to take Jingzhou, you must kill Guan Yu. But Guan Yu was, after all, a general of bears and tigers in the Three Kingdoms era, a heroic hero. Guan Yu did not mean to take it away, but to take it away. It took a chance. So this opportunity is coming soon. In the twenty fourth year of Jian’an, what happened in the twenty fourth year of Jian’an? On the first month of the 24th year of Jian’an, Liu Bei’s army arrived in Hanzhong. After watching the previous program, we know that at this time, Liu Bei already had Shu, Shu and Hanzhong, and the entire Yizhou was owned by Liu Bei. In July, Liu Bei became king in Hanzhong, calling himself “King of Hanzhong.”. After becoming the King of Hanzhong, Guan Yu sent troops to attack Xiangyang and Fancheng in the same month, which was known as the “Xiangfan Campaign.”. Guan Yu’s action now seems to have coincided with Liu Bei’s victory in Hanzhong, as in July Liu Bei became king in Hanzhong, and in the same month Guan Yu attacked Xiangfan.
关羽攻打襄樊开始的时候非常顺利。八月份，襄樊地区天降大雨，山洪爆发，洪水把樊城围起来了。这个洪水淹没了曹操派来救援襄樊的于禁的七军，这就是所谓“水淹七军”。那么关羽趁着洪水，自己驾着船和于禁作战，俘虏了于禁，杀了另一位很勇敢的将军庞德，叫做“降于禁，斩庞德”，初战告捷。这个时候守樊城的是曹仁，曹仁的决策是死守，同时曹操也派了徐晃带兵来救。那么这样，襄樊战争在八月份以后，也就是关羽初战告捷以后，就处于相持阶段。一方面是曹仁的守军、徐晃的援军，另一方面是关羽的部队，相持不下。那么这样的一个情况下，关羽就是进也不得，退也不得。因为现在关羽要拿下襄阳、樊城，仅有的力量是不够的，必须从后面派兵增援；一旦增援，那他的后方，也就是南郡这个地方就会空虚。关羽这个时候是犹豫的，不知道该怎么办。吕蒙马上上书孙权说：机会来了。
Guan Yu’s attack on Xiangfan began very smoothly. In August, it rained heavily in Xiangfan area, and mountain torrents broke out. The flood surrounded Fancheng. This flood submerged the Seventh Army sent by Cao Cao to rescue Yu Ban in Xiangfan, which is known as the “flooded Seventh Army.”. Guan Yu took advantage of the flood and drove his own boat to fight against Yu Ban. He captured Yu Ban and killed another brave general, Pound, known as “Surrender to Yu Ban and behead Pound.” The first battle was successful. At this time, it was Cao Ren who guarded Fancheng, and Cao Ren’s decision was to defend it. At the same time, Cao Cao also sent Xu Huang to lead the troops to save it. In this way, the Xiangfan War was in a stalemate stage after August, after the victory of the first battle of Guan Yu. On the one hand, it was Cao Ren’s garrison and Xu Huang’s reinforcements, and on the other hand, it was Guan Yu’s troops, which were at a stalemate. In such a situation, Guan Yu could neither advance nor retreat. “Because now Guan Yu wants to take Xiangyang and Fancheng, his only strength is not enough, and he must send troops from behind to reinforce them.”; Once reinforcements are provided, his rear area, South County, will be empty. Guan Yu was hesitant at this moment and didn’t know what to do. Lv Meng immediately wrote to Sun Quan and said, “The opportunity has come.”.
