Crossing the shadow shop deep in the shadow alley, you can hide the obsessions of the world and suppress the evil shadows in the world.
Shen Yan is the last person to cross the shadow. He carves marks on his bones and guides his residual thoughts. He uses himself as bait to guard the shadow core, protect old things, and avenge his master.
He thought that Xuan Ying, the master of the Shadow Hunter Pavilion, was the ultimate source of evil, but he did not expect that hundreds of years of disputes and obsessions turned into demons, all controlled by the Shadow Eclipse in the deepest part of the Shadow Gate - that was the negative origin of the obsessions of the first generation of Shadow Crossers. It fed on the resentment of the world and wanted to swallow up all the obsessions and make the world a state of death and silence.
When the Master of the Pavilion of Tragedy was reduced to a pawn, when the palm of the seal-guarding girl shone with light, when the bone mark of the Shadow Crossing Man resonated with the obsession of the first generation, Shen Yan held the Shadow Crossing Hairpin and stood side by side with Su Wan, with the thought of protection and the control of thoughts with obsession, vowing to seal the Shadow Eclipse and guard the warmth of the last ray of obsession in the world.
