Deliver Food to the Underworld and Become a Billionaire When You Come Back

I am an ordinary person, my life is full of ordinary, ordinary work, ordinary income, ordinary appearance. I'm almost thirty and still can't find a girlfriend. But the change came that day. I received an order for a crematorium. Although it was at night, the amount was very high, so I accepted the order. I didn't expect it wasn't ordered by anyone at all? Since then, I would pick up money for no reason, I would have money when I woke up, and I could make money while lying down. And such good things? It seems that the next richest man is me!
