If You Catch the Ghost Land, You Still Have to Fight Monsters and Pay Off Your Debts.

The debt I owed to ghosts in my previous life was transferred to me in this life, and I was caught in a ghost land to repay the debt. What happened? Can you go back after paying off your debt? Can I still fight ghosts with a small sword in my hand? After enduring it for who knows how long and going through ninety-nine and eighty-one hardships, the debt can be said to have been paid off. I thought I could go back, but you told me that all this was fake and fabricated by the final boss. I still have to finish the boss? I can't even beat the little guys. What to do, my God!
