The sky gradually darkened, as Qin De sat cross-legged in the center of the Reverse Eight Trigrams Formation in the valley. Feng Yuzi and Qin Yu, among others, were seated randomly around Qin De. As time ticked by, the fifteen people in the valley knew the Heavenly Tribulation was approaching, and everyone was on edge.
"Father," Qin Yu slightly turned his head to look at the meditating Qin De. At this moment, Qin De's face was calm, but Qin Yu's heart suddenly trembled. To resist the might of the Heavenly Tribulation for mortals was extremely difficult, even the weakest Four-nine Heavenly Tribulations.
"No matter what, I won't let anyone disturb you," Qin Yu's eyes grew more intense.
