967 Trapping Immortals, Tribulations Fall Like Rain

"Eh, what's going on?" At this moment, the Gu Immortals of Southern Border, who were situated ten thousand li away from Yi Tian Mountain, looked at the sky one after another.

Even the mortal Gu Masters on Yi Tian Mountain also felt an indescribable chill.

Rumble…

A vague rumbling sound could be heard coming from the sky.

Several breaths later, the rumbling got louder and louder, as if hundreds of people were beating war-drums far away.

Ever since Fang Yuan stepped on Yi Tian Mountain, he had been making use of every second in refining the battle will, but the commotion in the sky right now was getting louder and louder, he had no choice but to temporarily stop his work and look above.

From high up in the air, he saw the sky suddenly brightening with a series of white light specks.

These light specks were extremely vast in scale and densely packed together. They started to fall rapidly and powerfully down towards Yi Tian Mountain.
