Boom!
Fang Yuan waved his sleeves, black smoke spread out to the surroundings, he had used soul explosion.
This was a rank seven peak method, it immediately destroyed the core of the immortal formation on cloud bamboo mountain range that Chi clan had created with ease.
Rumble!
There was another explosion as the formation's core broke apart, the other areas of the immortal formation also collapsed.
At this point, the entire mountain range's formation was destroyed.
"They left after all." Looking at the empty place, Fang Yuan's gaze was dark and unsurprised at all.
His attack on the formation earlier was met with great resistance that was quite skillful. But later on, Fang Yuan noticed that the immortal formation was getting more slow in reacting to his actions.
Immortal formations and Immortal Gu Houses needed people to manipulate them. Even wills or formation spirits left behind could not replace the use of a Gu Immortal.
