The veteran assassin Youhuang was reborn three years ago when he assassinated the tyrant, but found himself trapped on the day he entered the palace. After 98 deaths, she was completely defeated for the 99th time and threw the poison in front of the tyrant. However, the legendary violent king raised his eyes, and in his eyes was the same tiredness and understanding as hers, having gone through endless reincarnations. "You too?" He asked. Two full-level reincarnations were forced to form an alliance. In the endless time cage, they went from being drama queens testing each other to each other's only anchor point. Before the cycle ends, they must find out the mastermind who stole the country's destiny and learn to truly trust each other - because this time, the sword that pierces fate requires both of them to wield it together.
