Because the luxurious tomb has not been completely built, there is no burial. In order to prevent malodor, the body will be coated with special antiseptic spices, and the smell of the body will basically be covered up. The biggest source of bad smell should be feces. A huge funeral used a lot of camels and horses. Because of walking slowly, camels and horses will leave feces all the way. This shit will smell after a long time.
