Once he traveled through time and became a prisoner of the Great Qin Mausoleum, Chen Zhou thought his life was over. But he holds the entire history of the rise and fall of Great Qin in his mind! Faced with the mistreatment of the supervisor, he came up with a plan to make it impossible for him to recover! Faced with the bullying from his companions, he showed off his skills and convinced everyone! Until that day, he rescued the beautiful princess who had been forgotten by everyone - Ying Shuyu from the collapsed imperial mausoleum. One is the lowest prisoner, and the other is a powerless princess. Two of the most unlikely people in the world have formed the strongest treason alliance! You are responsible for being as beautiful as a flower and acting as the sharpest knife in Da Qin. I am responsible for strategizing and being the deepest shadow behind you. The harem is our intelligence network; the court is our chessboard; the world is our prey! When Chen Zhou assisted Ying Shuyu to reach the peak of power step by step, the entire Qin Dynasty suddenly woke up: It turns out that the real ruler of this empire was never the aloof First Emperor, but the shadow emperor hiding behind the princess!
