Yun Jiuchuan, the chief soul judge of the Soul Judgement Department, uses a soul lamp to determine the reincarnation of the soul, and distinguishes good and evil with a pair of wise eyes. However, while escorting a wisp of "Wuji Soul" to Wangchuan Ferry, he encountered a strange soul-eating fog - a black fog that can eat away memories. It not only kidnapped Wuji Soul, but also planted doubts in his heart.
Tracking the source of the fog to Mizong Ze, he met the blind girl Aying. Her fingertips can touch the soul words, and the jade pendant around her neck contains secrets. The resonance with the soul-suppressing seal fragments he carries with him actually involves the afterimage of the war in Jiuchuan a hundred years ago. The "fracture lines" in the souls of the villagers, the bronze masks of the Shadow Pavilion forces, the truth of the past lives reflected in the Bone Lamp River, the obsession tempered by the fire in the heart of the Red Flame River... As the soul-suppressing seal fragments appear one after another, Yun Jiuchuan gradually discovers that he is not only guarding the order of souls, but also the family secrets and Jiuchuan's destiny that have been buried by time.
When Shadow Pavilion's ambition to destroy the world collides with the lawful way of Soul Sentence Division, and when the true power of the soul-suppressing seal swings between hatred and reconciliation, Yun Jiuchuan and Aying move forward with broken memories and the whispers of the soul. They will eventually understand that the sword of the soul judge can not only cut off reincarnation, but also sew people's hearts together; and the so-called soul-killing is never about sealing the past, but about allowing every obsession to find its own way back.
The storm in Jiuchuan is rising again, and the soul lantern and the bone lantern are shining brightly together. Let's see how these young people, who are bound by destiny, will open the way forward in the fog, allowing the sleeping truth and the unyielding warmth to shine together into the human world and the soul world.
