Lin Qi inherited the old house his grandfather left behind, along with a string of copper bells.
When the bells ring, every ghost in the area has to behave and call him "landlord."
While other people inherit an estate, he inherits a house full of tenants:
A Jiao, a Republic-era female ghost, is sharp-tongued but soft-hearted. She shows up every night on the dot to "borrow some yang energy." Before long, she ends up in his bed, with a perfectly reasonable excuse: "We're idle anyway. Not making use of you would be a waste."
Su Wan, a young woman fallen on hard times, arrives to rent a room with a haunted trunk in tow. She's the biggest scaredy-cat, but the most diligent about paying rent. One night, she gets up to check the fire and accidentally catches the landlord in the middle of a good time. She's so embarrassed she can't lift her head for three days.
A clump of fire that fears the dark squats in the stove. Unable to pay rent, it works off its debt by keeping the fire going every day. It reports when the water boils, hangs a lantern after dark, and has to burn bright all day during festivals.
Relatives come to seize the deed? The bell's mark burns their hands, and it won't fade for six months. A vicious ghost comes to the door to snatch someone away? It can ask about the rules of this house first. A female ghost sneaks into his bed at midnight? Lin Qi doesn't even raise an eyelid. "Rent comes out of your allowance. Yang energy costs extra."
Other people are scared witless exploring haunted houses. He makes a fortune collecting rent in one.
The lamps stay lit, and the stove never goes out.
Ghosts are cleaner than people. Once you enter this home, you're family, and no one gets to leave.
It was green at the beginning. Don't look at it. The two protagonists in the two novels updated by the author are either driving a bus, or they were banned immediately after being green.
