Lv Meng is a general under Sun Quan's account. Battle of Red Cliffs, Sun Liu alliance defeated Cao Jun, and also made great military achievements. Sun Quan thinks that Monroe is a material that can be made in the world, thinking: Monroe is very clever, but he is foolhardy. If he can study hard, he will succeed in the future.

So, one night, Sun Quan invited Lv Meng to drink and chat under his account, and Lv Meng arrived as promised. After three glasses of wine, Sun Quan stood up and walked beside Lv Meng. Lv Meng also stood up respectfully. Sun Quan patted Lv Meng on the shoulder with a smile and said, "Ai Qing is now in charge of affairs and has great responsibilities. You can't help studying! " Lu Meng thought: I am a military commander. In this troubled times, what's the use of learning these as long as I can arrange my troops and be brave and good at fighting? Therefore, Monroe said, "Master, there are too many things to study in our army. Please forgive me. " Sun Quan is very angry, but because of his status, he needs to take care of the overall situation. Instead of losing his temper, he turned around to control his emotions. Then he said, "Do I want you to study Confucian classics and be a scholar who specializes in teaching Confucian classics?" Sun Quan said gently: "It's just that we have to read books and understand history. You said that your army has many affairs, and I am the king of a country. Who has more affairs than me? I often read books, and I think reading makes me gain a lot. " Hearing this, Monroe's heart thumped and she thought, "Why don't you try? Anyway, there is no reason to refuse. " So, Lv Meng began to study.

One day, Lu Su went to Xunyang to visit Monroe and said, "How's my brother recently?" "It's good to study recently." So, the two began to discuss personnel. After a few words, Lu Su felt that Lu Meng was not what he used to be, and that his talent and strategy today were no longer under me. He said: "My brother's talent is no longer the Monroe of martial arts." Lv Meng smiled and said, "Brother, talented people like you and me should look at each other with new eyes. Why did my brother recognize things so late? " Monroe and Lu Su joined hands and went to Monroe's mother's room to let Lu Su meet each other. They became half-brothers with Lu Su and were reluctant to part.
