A Zhu, a young man from Qinglan Valley, guards a mist-shrouded pure land, and his life is as ordinary as a stream. When he arrived at the edge of the misty forest, he bumped into Shen Hanzhou, a man in black clothes who was unconscious with a fatal arrow wound.
A sudden pursuit draws two people who have no intersection into the whirlpool of fate. In order to save Shen Hanzhou, A Zhu stepped into the forbidden misty forest, but his peaceful life was completely shattered. Not only was he hit by an arrow in his back, but he also fell into the swamp with Shen Hanzhou during his escape and almost died.
After waking up, A Zhu discovered that Shen Hanzhou was anything but an ordinary person. The strange arrow feathers glowing with purple light on his chest, the "leader" in the mouth of the pursuer, and the power that Shen Hanzhou occasionally revealed, which was far beyond ordinary people, all pointed to a fantasy world that he had never touched. And the way Shen Hanzhou looked at him gradually changed from the initial vigilance and indifference to a complicated bond.
When the mist of Qinglan Valley can no longer hide secrets, and when larger forces follow the trail, A Zhu has to leave his comfortable homeland and follow Shen Hanzhou on an unknown journey. He wants to find out Shen Hanzhou's identity, find out the truth behind the pursuit, and more importantly, in this fantasy world where human life is like a piece of grass, keep his purity and kindness that comes from the mountains and fields.
The fog is heavy and the road ahead is treacherous. The two people whose fates are entangled will uncover the shocking secrets hidden under the fog together in the light of swords and adventures in the secret realm. They will also write a legend about bonds and perseverance in each other's redemption and growth.
