Fish scale nevus is wiped with paper money. Don't look back. Will it take off slowly overnight?

The small one will take off slowly in a few days, and the big one will take off slowly, which means a long time. Because I fished and scraped fish scales every day last year, I may not have cleaned them, and I don't know when I grew a dozen pieces, big and small. Some time ago, I heard from my family that I would slowly get rid of it with paper ashes that burned paper money. Now there is only one big one left in my hand, which will wither slowly and fall off soon (of course, I don't believe in ghosts and gods, but it does work. Maybe something is burnt.
