Mortal King in the Shackles of Qiling

Borrow money from the dead four thousand years ago - borrow fire, borrow life, borrow days you don't deserve to live. This is the way of this world. Sign a contract and you can call upon ancient powers. The price is that creditors will eventually come knocking on your doorstep. The footsteps in an empty house, the person folded into a piece of paper, standing in the living room late at night waiting for you - those are not ghosts, they are debts from four thousand years ago that are collecting interest. No one knows what the crack in the North Pole is. I only know that it has been implemented for forty years and has not yet been completed. And what can you, a human being bound by rules, do?
