Longevity begins with Orion

The previous one didn’t explain it clearly (it’s actually written in the main text, but because it was mixed into the plot, some book friends may not have seen it clearly).

1. The reincarnation of this world takes place in the "Reincarnation Realm".

2. The "underworld" was only formed later and does not have the function of "reincarnation". It only absorbed some ghosts from the Human Emperor period because it was too close to the mainland. (You can think of the "underworld" at this time as an independent, non-functional "small world")

3. The "Reincarnation Realm" uses the "Soul Furnace" as the main body, and the "Taiyin and Sun" as the "furnace fire" and "condensation" to dissolve all living souls and then condense them again.

All reincarnations take place here.

But today, a small part of the "Reincarnation World" has problems, and most of them are still operating normally (Chapter 278, when the assembled gods and demons crossed the long bridge of flesh and blood, and arrived at the ancient temple without an exit, they lay on the edge of the corridor and saw )

4. Because there was a problem with the "Soul Furnace", and the problem further worsened after the "Great Change of Heaven and Earth", the "burning" was incomplete, and some souls would occasionally be missed to be burned, causing these souls to be able to cherish the dreams they had during their lifetime. Partial memory reincarnation (Chapter 279, Hu Yanhai is this example - this is not a spoiler at all, because it is almost stated clearly)
