Whether he was a human, a landlord of unusual creatures or the executor of a goddess, Hao Ren could not have ignored the coming of The Day of Return. No matter what the truth was, it had the potential to disrupt the equilibrium on Earth. To stop it or not to stop it, he really did not know—he felt helpless to do so even if he wanted to.

Before the two elders left, they had also mentioned about the event: the last siren left the surface in 1976. Finding these messengers was mission-impossible. There may have been others like Nangong Wuyue's mum, who discarded her mission but, no one knew where they were. It was like finding a needle in a haystack. Hao Ren had no intention of looking for them for the time being.
