Two lives traveled through time, both of which were Wei Yan. In the first life, he personally experienced the miserable rain of Wuzhangyuan, harboring regrets about the "Ziwu Valley Conspiracy". After Zhuge Liang's death, he was framed by Yang Yi, and died under the sword of Ma Dai amidst the mournful cry of "Who dares to kill me?", Leaving him with the eternal infamy of "there is a traitor in the back of the head". The moment blood soaked his neck, he vowed that if there was an afterlife, he would use his wisdom to turn things around and no longer be a strong man who could be slaughtered by others.
Once reborn, he returned to Changsha City after the war in Chibi and became Wei Yan, a young man who was still under Han Xuan's command but had not surrendered to Liu Bei. This time, he hid his sharp edge, restrained his stubbornness, used prophethood as an edge and forbearance as a shield: when Guan Yu attacked Changsha, he secretly arranged a chess game to not only save Huang Zhong's life, but also use his "dedicated city" to avoid Zhuge Liang's "killing Wei Yan". When he entered the battle in Shu, he predicted Zhang Ren's ambush and outsmarted Luocheng, quietly accumulating merit and popularity; when he was in Hanzhong, he improved the defense system, hoarded grain and grass, trained warriors, and turned Hanzhong into an iron-barreled country.
During Zhuge Liang's Northern Expedition, he followed Zhuge Liang openly and secretly, using the improved version of the "Ziwu Valley Strategy" to achieve great successes, but always hiding his edge. When Wuhou passed away, he thundered away Yang Yi, stabilized the morale of the army, gradually ignored Liu Chan, and finally succeeded Han Zuo in the name of "Qingjun Side". Then he competed in the Central Plains. He took advantage of the rebellion of the Sima family to usurp the Wei Dynasty and attacked Chang'an by surprise. He recaptured Jingzhou with the ingenious strategy of water warfare.
