I Was About to Rebel When Li Shimin Put on a Yellow Robe for Me

Li Jian transmigrated to another world in the Tang dynasty, becoming Li Shimin's twelfth son. To avoid becoming a pawn in the future struggle for imperial power, he could only keep a low profile and wait for the right moment. In the fifteenth year of the Zhenguan era, just as Li Jian was preparing to make his mark, Li Shimin acquired a life simulation System that could simulate the entire lives of his descendants. Li Shimin simulated the life of Crown Prince Li Chengqian and discovered that his eldest legitimate son would openly rebel and be demoted to commoner! He simulated the life of Prince Wu Li Ke and discovered that his third son would be framed for rebellion by a powerful minister and die with his name in disgrace! He simulated the life of Prince Wei Li Tai and discovered that his second legitimate son would be demoted after fighting for the succession and die young, far from home! He simulated the life of Prince Jin Li Zhi and discovered that his chosen successor would hand the Tang realm over to another house, leaving the imperial clan slaughtered to the last! The Tang dynasty's hold on power was hanging by a thread, and nine out of ten descendants met a tragic end. Li Shimin could not help lamenting, “My sons are all mediocre and incapable of shouldering the burden. What wrong have I done against Heaven? What is my crime?” Fortunately, as the simulations added up, Li Shimin discovered that no matter how turbulent the political landscape became, one man always stood firm. His twelfth son, Prince of Dai Li Jian! A hidden dragon in the deep, he would astonish the world with his first appearance, save a crumbling dynasty and turn the tide at the brink of defeat. Carrying on the legacy of Zhenguan, he would write a new chapter in the High Tang. In Li Jian's hands, the realm was destined to become a glorious Tang dynasty, renowned through the ages! And so, as Li Jian went about his business, he suddenly found his dear old father personally draping a yellow robe over his shoulders. (A lighthearted flights-of-fancy story. It won't get too heavy, but the characters' inner lives will be explored in depth.)
