Reborn as a death row prisoner of the Qin Kingdom that was about to be destroyed, Li Mu only had one day left to live. When the young King of Qin Zhao Heng came to prison with his last glimmer of hope, what Li Mu offered was not gold and silver, but the historical direction of the next hundred years! "Your Majesty, the Chu army will sneak attack from the west gate tomorrow night and attack its grain and grass camp at night. It can be destroyed!" Overnight, the death row prisoner became the national advisor, and the prophecy became a reality. Inside, he defeated the traitor and purged the officials; outside, he cleverly used a series of tricks to defeat the strong with the weak, and fought the strong to cede territory for peace. When the Qixiong trembled, everyone thought that this was King Qin's destiny. Only Zhao Heng knew that the man beside him was the real chess player.
