After you die, you are mummified. Your organs are taken out except your heart. Then a scarab amulet is put over it. Lastly, you are covered in linen soaked in resin.
While your body is being preserved, your soul has to go through monsters, burning rivers, and gates.
Tests too! You have to make the assessors believe that you have lived a good life. There are 42 assessors in total!
But all of this is possible with these two items: a book with spells and the scarab amulet. The spell book helps you go through all those monsters and the scarab amulet lets you lie in front of the assessors.
Finally, you now have to pass the last test! To pass this test, you have to meet Anubis, one of the gods and your heart has to be either the same or lighter than the feather.
When you pass that test, you're there in the afterlife! You can meet your family who has already passed all the test. And there, you have to cultivate land for eternity. In the afterlife, you can't feel any pain or feelings.
