In 649 AD, Li Shimin, Emperor Taizong of the Tang Dynasty, died of illness in the Hanfeng Hall of Cuiwei Palace, but his consciousness did not dissipate. When he opened his eyes again, he turned out to be Liu Bei and Liu Xuande, who were selling straw sandals on the streets of Zhuo County in the late Eastern Han Dynasty. He was 24 years old at the time, just before the Yellow Turban Uprising. Relying on the wisdom and methods of the founding king of the Tang Dynasty, Li Shimin resumed his struggle for hegemony in troubled times as "Liu Bei". He used strategic vision and political skills that transcended the times to accelerate the unification process. However, in the process, he encountered a fierce collision between ideas and the limitations of the times.
