Once upon a time, he was Gu Changye, the "Changye Sword Immortal" who stood at the top of the world and could cut through the stars with one sword. A catastrophe swept through the three realms, causing his foundation to be completely destroyed, his soul to be broken, and he fell into the mortal world with his young daughter.
Today, he is the owner of a mysterious shop called "Wuyou Pawn Shop" in the corner of the bustling city. This pawn shop does not accept gold, silver and jewelry, only "troubles", "obsessions", "fear" and "memories". The ancient copper bell in the pawn shop that never opens the door is his "system" - whenever there is an "thing" that cannot be solved by ordinary means approaching, the copper bell will ring on its own.
In order to give his daughter Gu Nian'an a stable childhood, and to find an opportunity to repair his own soul, Gu Changye started a "pawn collection" business.
"Miss, you are haunted by the ghost in the mirror. I'll pawn your 'ten-year face' away from you."
"Sir, you are haunted by the deceased, and you dream of returning to the battlefield every night. As a pawn of your 'memory of killing', I will allow you to have a peaceful night's sleep."
"Kid, this ghost doll wants to take away your life and pawn your most beloved toy. I will turn it into a real doll."
During the day, he is a gentle dad who washes hands and makes soup for his daughter and tells bedtime stories; at night, he is a mysterious being who wanders between urban legends and taboo stories, and deals with ghosts and evil spirits. But Gu Changye didn't know that the daughter he regarded as a treasure seemed to be hiding a secret that even he couldn't see through... And the true source of the catastrophe that caused his fall was quietly awakening in this mortal world.
