My Younger Brother, Li Shimin

The sixth year of Daye, the New Year in the Eastern Capital. Li Jiancheng had an extraordinarily long dream: In it, the Sui dynasty fell and warlords rose everywhere. He and his younger brother stood by their father's side, raising an army in Jinyang, entering Guanzhong, defeating the other warlords, and uniting the realm. In the end, he personally helped the Li family ascend to the imperial throne. But at Xuanwu Gate, brothers turned against each other and kin slaughtered kin. An arrow pierced his heart, shattering his life. When he opened his eyes again, he was not beneath the bloodstained palace gates of Taiji Palace. Instead, he was in a bright, spotless classroom, studying history and praising the everlasting achievements of Emperor Taizong of Tang. The dream was over. Yet he was still in the sixth year of Daye, still Li Jiancheng, heir to the Duke of Tang. But he soon discovered that he was far from the only one in this era who had returned with the “future.” So, in this even stranger and more inscrutable sixth year of Daye, Li Jiancheng lowered his gaze to the still-young Li Shimin and smiled as he patted his shoulder. “Second Brother, our ambition as brothers is to conquer the realm!”
