After the death of Emperor Zhenguan, Li Shimin, he thought that his merits and demerits were settled and he returned to the earth. However, he suddenly woke up in a strange and familiar palace and found that he had become Liu Chan, the empress of the Shu Han Dynasty. At this time, the Shu Han Dynasty was in turmoil. The late emperor had passed away, and Prime Minister Zhuge Liang was solely responsible for the crisis. The civil and military forces of the central court despised the young master, the Qiang and barbarians in the border areas were undecided, Cao Wei in the north had strong soldiers and horses, and Eastern Wu had alliances and rebellions. Although Bashu was dangerous, it was hampered by the constraints of food roads, population and noble families. When Li Shimin entered this body for the first time, he had to hide his edge and stabilize the situation, while also reestablishing imperial power within the constraints of Liu Chan's original reputation and identity. He turned the old knowledge of Zhenguan into modern skills, starting from knowing and employing people, rectifying the administration, laying off redundant officials, cultivating fields and building canals, transforming ordnance, and reshaping the imperial army. Step by step, he transformed the Shu Han from a country of peace to a peaceful country, and forged it into a strong man who dared to compete in the world. At the same time, he and Zhuge Liang turned from the temptation of monarchs and ministers to co-governance, corrected the key mistakes in the Northern Expedition in advance, overturned the defeat of Jieting, and made Jiang Wei, Huang Yueying and others the backbone of the New Deal and the New Army. Faced with the internal struggles among Cao Wei and the vagaries of Soochow, he not only used royal orthodoxy to appease people's hearts, but also broke the balance of power among the three kingdoms with thunderous military fronts. In the end, this resurrected hero will reshape the destiny of the Han Dynasty in the name of Liu Chan, and complete the destiny-defying transformation from "the empress of the country's subjugation" to "the king who rebuilds the empire" in troubled times.
