For old foxes like Xie Xuan and Elder Wu, even the slightest disturbance can make them sense something wrong.
Zhang Shicheng clearly has the absolute advantage, yet he abandoned the two at the critical moment. This is highly unusual!
There should be two possibilities for this situation:
The first is that the Water Fortune amid Heaven and Earth is too overwhelming, and the opponent has already suffered a backlash. The backlash might even be so severe that he can't endure the few breaths needed to kill the two of them. Isn't this the best time for the two to beat a drowning dog?
The second possibility is that an unforeseen change forced Zhang Shicheng to leave. In that case, the two need to go back and see if they have a chance to beat the drowning dog and kill Zhang Shicheng.
"First destroy the Feng Shui Grand Array, and then let's see what's happening with the Dragon Seed," Xie Xuan said, instead of rushing forward, discussing with Elder Wu.
