What kind of horrible punishment was the punishment of torture and persuasion in ancient times?

The instruments of torture for grooming are very simple, just an iron brush and an iron bed. The cruel process makes people shudder just listening.

First of all, the punished prisoner should take off his clothes and be punished naked. The prisoner lay naked on an iron bed.

Then, the jailer will pour boiling water for the prisoner several times, and his meat will be boiled half-baked. At this time, the jailer will comb the flesh down again and again with the iron comb in his hand, so that the half-baked flesh is not easy to peel off, which increases the pain of the prisoner. This biting pain is worse than death, and the prisoner will be tortured to death before long.
