This was the second time Zhao Changhe had encountered an opportunity that required "waiting for the right heavenly moment"; the last time had been in the ancestral land of the Spirit Clan, where he had also benefitted. He understood this pattern well.
In fact, the so-called heavenly moment is combined with the advantage of location. In the case of the Spirit Clan, it had to be at the ancestral land, the site of the Spirit Platform. The opportunity for Chichi also required a specific location, although it was unclear what made that location special.
Xia Chichi was free to set out to sea at any time.
