Murim’s Debt King

A brief description of the manhwa Murim’s Debt King:
A place where money is needed to sharpen a sword, to feed and clothe your disciples—no, to simply breathe.
The Murim.
Do you need money? Has your credit rating dropped? Then come to the Continental Battlefield. Unsecured same-day loan approval.
You don’t have the money to pay? Ah. Don’t worry. We accept your body. Relax! You’ll get injured! Thank you, sir!
