Death Contract

A resurrection contract from a hundred years ago made Lin Shen, an ordinary social worker, begin to see the "creditor" on the boundary between yin and yang. The copper coin was engraved with the word "debt", and it always faced him no matter how it was turned over. The deed holder moved the abacus, and his name lined up and rotated on the abacus beads. The countdown in the mirror decreases day by day, and black liquid drips into numbers on the table. The debt owed by grandpa will eventually be borne by him. But Bai Jiu said: If you want to cancel the contract, you have to exchange your life - use your own life to pay for your own life. What kind of equivalent exchange is this?
