Li Mu was reborn from the mountain of corpses and returned to the first year of "Yongchang" in the new dynasty. In his previous life, he died of hunger in troubled times. He was a humble clerk in the new dynasty. He accidentally discovered the irrefutable evidence that his uncle had collaborated with the enemy and treason, so he was silenced and his body was exposed in the wilderness. When he opened his eyes again, he was holding the half piece of blood-stained steamed bun, standing outside the examination room of the imperial examination of the new dynasty. In this life, with his deep-rooted memory of his enemies and accurate prediction of the direction of history, he decided to change his way of life. With his prophetic power, he broke into the emperor's eyes with his astonishing talents, and he jumped from a refugee to a close minister of the emperor. Xiao Che, the emperor on the dragon throne, has great talents and great plans but is hampered by his relatives. He is the wise emperor who created the "Government of Yongchang" in his previous life. He is also... The person who was kind to him in his previous life but failed to protect him. Hidden in Li Mu's sleeve was a secret letter that could shake the foundation of the country - a shocking secret about the emperor's life experience. Uncle Guo's gang members are like poisonous snakes, constantly trying to make trouble; Zhao Feng (Protagonist 2), his former savior and now a military general, is naturally suspicious and wary of him. Is it to ignite the secret letter, stir up the storm, and seek revenge on all those who have failed him? Or should he hide his sharp blade, use his chess skills to assist Mingjun, and personally create a true peace that will not let "little official Li Mu" die in vain? Every decision he makes is dancing on the edge of a knife, and the border war in three years is approaching silently.
