Lin Xiaoxiao is eighteen years old, but her mind is stuck at the age of seven. Neighbors called her "Silly" and relatives said she was "unlucky". Only her grandmother protected her. Until the day when grandma passed away, she smiled and said to the empty corner - "Grandma has light on her head."
Everyone thought she was crazy. But they didn't know that Lin Xiaoxiao could see it. See the light left by the deceased in the world, see the soul trapped in the corner, and see the seven sealed gates underground in this city. And she is the key to the seventh door.
Brother Lin Yu is a forensic doctor and firmly believes that science can explain everything. Until he saw his sister speaking into the air with his own eyes, and bloody handprints appeared on the floor. He opened the encrypted notes left behind by his father when he died in the line of duty, and realized that the secrets carried by this family were far heavier than imagined. My father sealed the fourth door, my mother dedicated herself to the fifth door, and my grandma spent twenty years of her life raising a soul-soothing jade pendant. Now it's Xiaoxiao's turn.
She carries the lock seals of five doors, and is accompanied by a priest spirit who has lived for a thousand years, a female graduate student who has been investigating the truth for five years, a supernatural blogger who lost her sister, and a veteran who has been guarding the door for twenty years. They have to walk through seven gates together, face the shadow evil spirits that devour spiritual bodies, face the gatekeeper family who are crazy about resurrecting their loved ones, and face things that stretch out from the deepest part of the seal.
But this is not a story about "fighting monsters and leveling up." This is the story of a silly girl who teaches everyone what "farewell" means in the purest way. When the seven doors were sealed and the key was taken out of the keyhole, she could finally live a normal life. But she found that the door was closed, but the key was still there
