When Kyrgyzstan is buried, will the bones change color?

When the tomb is buried in Kyrgyzstan, the bones will change color. Bones change color wherever they are. The bones turn black because of the heavy moisture in the tomb. Bones will turn black when they are wet for a long time, and even rot for a long time, leaving no trace except a piece of black soil. Bones turn gray and brittle, and they will break when touched lightly. This situation is caused by the wind in the grave. Bones are exposed to the sun for a long time, which will turn gray and rot completely.
