How do ancient Egyptians preserve dead bodies

It took 70 days to go through mummification because they had to dry out the bodies and then they had to wrap linen around the pharaoh. The linen had to be very long which was as long as the Eiffel Tower. Then they would put the wrapped mummy into a coffin. When that was done, they would carry the mummy to the pyramids and put it in a room with their prized possessions.
