Clue (2)

At this time, another person who had been standing beside GUI Ying said, " "Senior brother, what if the other party collects all the yin Qi?" The one who spoke was Phantom. He and Phantom elephant had been following GUI Ying.

GUI Ying shook his head and said, " no, they're people from the lower realm after all. It's impossible for them to know the magical use of Yin Qi. If they knew, they would have cleaned up the yin Qi in the spirit weapon world a long time ago. It's not a good thing to leave so much Yin Qi in the spirit weapon world. If it's not handled well, ghosts might appear in the future. However, the other party didn't do so. It's obvious that they don't know about this, so we don't have to worry about this problem. &Quot;
