Deep in an old street in a bustling city, there is an antique shop called "Buyu Zhai".
The boss, Gu Changye, is a single father who lives an ordinary life with his daughter. He seems lazy and easy-going, but in fact he is a taboo existence walking in the world.
Buyu Zhai never trades money, only "stories" or "obsessions". Every ancient artifact that was sent was entangled with strange supernatural beings and profound cause and effect.
An ancient mirror that can reflect people's desires, a green lamp with longevity as oil, a broken sword that seals the evil soul of the battlefield...
In Gu Changye's eyes, these "forbidden objects" that could cause chaos in the world were just toys for his daughter Nian Nian or furnishings used to decorate the tea room.
He once shattered the sky with his feet, and cut through the underworld with his sword. Now that he has washed away all his glory, he only wants to keep a fireworks display in the world for his daughter.
However, when the sleeping gods and demons of the past began to awaken in the present world, and when the cause and effect of the past came to visit, this man who just wanted to be a qualified dad had to remind the world what the "Long Night" is...
"Dad, this hairpin is so beautiful!"
"Well, it's made from the spine of an old god. Let's wear it and play with it."
"Dad, why is this uncle kneeling?"
"Oh, he wanted to borrow our lamp, but dad didn't agree. Let him reflect on it."
