When the seventh heartbeat of the frozen city rang, the ice flames in Han Jin's palms and the dark thunder in Li Lin's eyes awakened at the same time. This city, imprisoned by eternal winter, will restart its memory every seven years due to an unknown supernatural resonance, and they are the only ones who remember the previous six times of destruction. Han Jing can freeze the fragments of time, and Li Lin can tear apart the cracks in space. The two are both old enemies and the key to fate. As the seventh heartbeat approaches, the ice crystal tower in the center of the city begins to devour the souls of the residents. They must unlock the truth sealed in each other's bodies before their memories completely collapse - otherwise, winter will never end.
