How to tattoo in ancient times

Wash the tattoo with saltpeter, coat it with truffles, and then wrap it for 5 days. On the 6th day, the tattoo was pricked with a needle, and the blood was dried with a sponge. If you sprinkle salt on the needle, after 65,438+00 sight distance (estimated to be the time unit), use the prescribed prescription and wrap it with linen bandage. Five days later, on the sixth day, apply a little prescription with feathers. You can go there in 20 days.
