In Longzhong, Zhuge Liang extensively studied astronomy, geography, military tactics, and other knowledge, with ambitious aspirations. In the twelfth year of the Jian'an period (207 AD), Liu Bei visited Zhuge Liang's thatched cottage in Longzhong three times and finally met him. Liu Bei sought advice from Zhuge Liang on how to unify the realm. Zhuge Liang proposed the famous “Longzhong Plan“: he suggested that Liu Bei first seize Jingzhou and Yizhou, reform politics internally, ally with Sun Quan externally, and wait for the right moment to launch a northern expedition from two directions to unify the realm. Liu Bei was impressed by Zhuge Liang's plan. Ultimately, Zhuge Liang was moved by Liu Bei's sincerity and decided to leave his reclusive life to assist Liu Bei.

　　在诸葛亮的辅佐下，刘备大败曹操于赤壁之战。其中，最为人称道的当属“草船借箭”的故事。建安十三年（208年），曹操率领大军南下，诸葛亮发现曹军兵力强大，尤其是箭矢充足，于是提出了一条妙计：利用曹操的多疑心理，用草船借箭。他命人准备了几十艘船只，船上装满了稻草人，并用黑色布幔遮盖。夜幕降临后，船只驶向曹军水寨。曹军看到黑压压的船队，误以为是敌军偷袭，纷纷放箭。结果，箭矢全部射在了稻草人身上。等到天亮时，诸葛亮指挥船只返回，带回了数万支箭矢。后来，刘备夺取荆州，攻取益州，建立了蜀汉政权。诸葛亮被任命为丞相，主持朝政。
