Five Dynasties and Ten Kingdoms: Li Shimin's Soul Passes Through Chai Rong and Determines the World

In 959 AD, Chai Rong, Shizong of the Later Zhou Dynasty, suddenly fell seriously ill during his northern expedition to Khitan. On his deathbed, Emperor Taizong Li Shimin of the Tang Dynasty received the opportunity of heaven due to the perfect merits of the "Zhenguan Rule". A ray of heroic soul crossed time and space and possessed Chai Rong and was reborn. Dual memory: Li Shimin has his complete own memory and Chai Rong's remaining memory fragments, and needs to adapt to his new identity through cognitive fusion. Historical deviation: The injection of Li Shimin's soul changed the original historical trajectory, but the law of heaven is conserved and the world line's converging force will still create obstacles. Core Contradiction: How did Li Shimin, as one emperor through the ages, quickly unify in the troubled times of the Five Dynasties that were full of evils? How to deal with Zhao Kuangyin and others who were originally designated as "sons of destiny"? He exists as "Chai Rong" but upholds the concept of "Zhenguan". How do the two spirits of the times blend?
