Lin Chunsheng was born with the ability to hear the souls of the dead in the abyss. A disaster forced him to follow Gu Chenyue, the leader of the Zhenyuan Division, on the road to eliminate the nightmare.

But the truth was revealed, and he was actually the sacrifice that Tianheng Sect had been looking for for many years. As the long night approaches, he must learn to no longer rely on anyone; and Gu Chenyue, who has always denied love, finally has to admit that this protection is no longer his responsibility.
