The Ancestral God Secret Realm.
Countless ice crystals covered a mirrorlike lake, in nine colors: red, orange, yellow, green, cyan, blue, purple, black, and white.
Those ice crystals varied in size. Some were only a few meters across, while others spanned tens of thousands of kilometers, like islands on the lake.
Mirror Lake.
It was a special location within the secret realm, similar to Nine Nether Space-Time, but less dangerous.
"Is this the place?"
Three figures descended over Mirror Lake and landed on a green ice crystal.
"The last time I sensed a Space-Time Demon Spirit, it was here," said the young man carrying seven swords on his back.

A Space-Time Demon Spirit's gene multiplier was only tenfold, making it one of the weakest special lifeforms, about on par with starry sky behemoths among ordinary lifeforms. However, two characteristics made it fairly well known.
The first was their numbers. Almost every few hundred or few thousand years, another Space-Time Demon Spirit would be born,
and from the beginning of this cosmic cycle until now, their numbers could be counted in the hundreds of millions.
However, seemingly due to restrictions imposed by the cosmic rules, someone had once calculated that no more than a million Space-Time Demon Spirits existed in the universe at any one time. Only when an old one died would a new one be born.

Space-Time Demon Spirits had two innate secret techniques, "Space-Time Synchronization" and "Possession." Space-Time Synchronization could
