Lin Mu's hand left a trail of light, as the Rune Shaping Brush kept on making tens of runes in a second.
"Just a bit more… they're getting closer too…" Lin Mu muttered to himself while keeping a part of his focus on the cultivators.
He was close to finishing the Sky Cull Grounding Formation and only needed a little more time.
Second after second passed, as Lin Mu's work approached completion. But the cultivators had sensed something strange by this time as well.
A couple of kilometers from where Lin Mu, a pair of Fourth Tribulation Stage Immortals were hidden.
"They've been silent for half an hour now." Daoist Jugu said to his companions.
"Yeah… they should have run away by now if they were able to." Daoist Rueshi replied.
"From the scene we saw, the attacks were very strong. Do you think the survivor is injured and can't move now?" Daoist Jugu asked, a smile appearing on his face.
