Li Ming, a modern social animal, travels back to Liu Chan, who has just ascended the throne, and faces the fate of "not wanting to miss Shu" and the crisis of the Shu Han Dynasty. He hid his wisdom, and by appeasing the people's hearts, rectifying the government, developing the domestic economy, improving the morale of the army, and expanding the territory, he finally allowed the Shu Han to strengthen its army and enrich its people, rewrite the ending of Han Zuo's decline, and open a new situation for the tripartite alliance of the Three Kingdoms.
