Due to his father's bankruptcy, Lin Zijin's dream of studying in Japan was shattered. When he cleaned up his grandmother's belongings, he accidentally unlocked the seal of "Hundred Demons of the Floating World" that was dusty in the attic - a hundred demons have escaped, and the world is in danger!
In order to clean up the mess, she bit the bullet and unsealed the legendary ancient demon "Flame" in the painting. Result? The first thing the demon king does when he escapes from trouble is to ridicule her and run away, leaving her alone to face the white-pink mother-in-law who specializes in skinning young girls!
When life and death were on the line, Yan still relented, because her face that looked like an "old friend" turned back to save her, but Lin Zijin quickly forcibly formed a contract with her and tied her to the pirate ship.
One man, one demon and one lamp were forced to go into business: Lin Zijin, who was doing a purchasing business with half a proficiency in Japanese while paying off debts, was looking for information about monsters, Homura, the venomous and tsundere, took action to eradicate the monsters at the critical moment, and the naughty and cute lantern demon "Ghost Lantern" who was loyal but stubborn, began a crazy journey to collect monsters.
In her previous life, she was the supreme witch, and he was the demon who loved her deeply.
A conspiracy, a sacrifice, she personally sacrificed him as the cornerstone of the seal. He should have been angry when he regained his memory, but he relented in the end.
In the firelight that filled the sky, he leaned down to block the fatal blow that the monster shot at her.
"You said you never want to see my face again. Why do you want to come back? If you die, I will owe you more."
"I will not die... But you... You will not allow me to die. Your life is not even worth the interest you owe me."
"Then how should I repay you?"
"That's not all yet. You can only stay with me, and you can't give a hair to anyone else..."
"Okay."

Purpose: "True protection is not to sacrifice others, but to still be willing to light the lamp of coexistence after understanding the darkness."
