In the third year of Yongchang under the Great Jin, the poor young Hu Zhang freezes to death in a ruined temple, starving and cold. With his last breath, he clutches the battered copy of the Mozi Canon that he happened upon, a book that changed his fate and ultimately led to his death. After copying an ancient star chart in the temple, he was accused of “peering into the secrets of heaven and plotting treason.” The great clans conspired against him, his closest friend betrayed him, his mentor died a horrific death, and his family was destroyed. When he opens his eyes again, he is reborn three years earlier, on the rainy night he first found the Mozi Canon.
