I Made My Fortune Selling Bizarre Cards

Mu Qiu has always felt that something is wrong with this world, but he has no proof, until a phone call comes.

As soon as Mu Qiu enters the village to find out what happened to his parents, he sees an old bachelor who's been dead for ages wandering by the river. A friend from years ago has become the village's inexplicable guardian.

Whatever's inside the locust wood plaque claims that he and Mu Qiu are a married couple, joined by their parents' arrangement and the matchmaker's words. To Mu Qiu, though, it's just some unknown species that's a drain on his finances, living entirely at his expense.

He gets into a strange school, and the moment he steps through the gate, he's saddled with an enormous debt. His parents' debt!

Mu Qiu grits his teeth. Luckily, he has a monster book. No matter how bizarre you are, I'll stuff you in there! Make me money!

And so there are:

Naturally Born Farming Mushroom: Pay to come farm.

007: Pay up and come lay bricks.

Special Sword: Pay to get beaten up.

Little Cube: Contribute money and labor to help build infrastructure.

Zhou Bapi: Gets sold and still helps count the money.

Mu Qiu successfully pays off his debts and makes a fortune. "I owe it all to the suckers who supported my startup, I mean... All our success belongs to the combined efforts of our employees and customers. Thank you, everyone!"
