Valley of Immortal Burial

Why did the way of heaven collapse? Hongjun's attempt to mend the sky failed because "one of them escaped" was not under the control of Heaven. Where did Hou Tu go? She did not die, but transformed into the "Remnant Core of Reincarnation", hiding in the deepest part of the Tomb of Immortals, waiting to restart the Six Paths. Angel world? They are not the angels of the West, but the enforcers of order "outside the territory" - the angel clan, who believe that the prehistoric immortals and Buddhas are against heaven and must be eliminated.
