Thirteen sects nominated him to be their Alliance Leader. Not because they respected him. Nobody wanted the job, and none of them trusted anyone else, so they put the most useless candidate in charge to take the fall.
Jiang Xiaoyu is nineteen, a third-rate martial artist, good at running, and useless at everything else. On his first day, he opens the account books: the treasury has just three taels of silver left, and all 137 "recommended candidates," from accountants to gardeners, are spies planted by the various sects.
The first thing other leaders do is kill someone to establish their authority. His first act is to post a public notice, copying every debt, down to the last coin, onto a wall. When an enemy sends him a coffin to intimidate him, he has it repainted and sets it up outside the shop as a screen wall, with a sign that reads, "A gift from a certain hero."
After that, he brings all the underhanded things in the martial world, a brush, an inkstone, a lock, a coffin, out into the sunlight one by one. He registers them in the ledgers and makes everyone sign for what they own.
The martial world values a fast blade. He values balanced accounts. But once the accounts are balanced, will the troubles be over? That night, someone climbs into his courtyard and burns his ledgers.
