Undecayed corpse
The ancestors of the undecayed corpse have no way to supply the resonance of this gene family. If the corpse does not rot, all the bones and bone minerals have no way to produce a half-life, called a half-life operation, it will not release the wave. The DNA of his descendants has no way to receive the wisdom of the ancestors' possession, and his wisdom naturally disappears, then the breed of your descendants will eventually be assimilated. The most famous ones are Egypt. When they just developed their Nile culture, they used the general undecayed body. The mummies are the undecayed bodies! You see so many mummies, its descendants disappeared, and their wisdom is gone. Now the Egyptians believe in Islam. There is no religion, belief, or wisdom in the era of the Egyptian Pharaoh. It is their high wisdom, and nothing is high at the end.
