Three years ago, a sudden "nightmare tide" turned the genius swordsman Xie Wujiu from the leader of the Nightmare Suppression Division into a traitor despised by everyone. He shouldered the injustice and disappeared from the eyes of the world.
Three years later, strange "nightmare disasters" occurred again frequently. Gu Xingyan, the genius array master who is currently the head of the Nightmare Suppression Department, met his former partner Xie Wujiu unexpectedly in a foggy village during his investigation.
One is a sword cultivator who has been framed, and the other is an array master who has been infamy. With opposing stances, they are forced to join forces to uncover the truth behind a series of "nightmare disasters".
Concept: In the eternal game of "light" and "shadow", trust is the only light that can penetrate the deepest fog. True protection is to choose to fight side by side despite misunderstanding and prejudice, and ultimately achieve the double redemption of others and oneself.
