As for the claim that during the Creation Calamity, when Pangu created heaven and earth, all three thousand Chaos Gods and Demons had been slain by Pangu?
The Great Dao was indestructible, and Hunyuan Great Firmament Golden Immortals were immortal. How could the Chaos Time Demon God, whose cultivation realm surpassed that of a Hunyuan Great Firmament Golden Immortal, be an exception?
Even if He had been cut down by Great God Pangu during the Creation Calamity, He certainly had not been completely destroyed. Perhaps He was still dormant, but perhaps He had already awakened.
And even if the Chaos Time Demon God had been slain by Pangu during the Creation Calamity and was still dormant now, so what? His inability to act in the present did not mean that His past self or future self could not act.
Taking himself as an example, if he were in the world opened up by the Chaos Gourd within Yuan Jie, he could easily manipulate and influence the River of Time, see through the past and future, and act upon them without any effort at all.
It would not be strange if the Chaos Time Demon God possessed the ability to act in the past or future and pull beings from the future into the past or present.
