It was precisely because of the existence of this seal that Master Cheng Shan had chosen the dharma title Cheng Shan.
This was his long-cultivated and famous artifact!
The Green Mountain Seal flew out of Master Cheng Shan's hand, swirling in midair, and soon grew to an immense size.
It changed from a miniature mountain that could be held in hand to a giant boulder several dozens of feet in size!
Such a massive stone seal, with just a casual strike, would possess unimaginable power.
Now, as it was being utilized by a Foundation Establishment Master, its power was naturally apparent under the reinforcement of the Foundation Establishment Realm's mana.
The Green Mountain Seal had not yet fallen.
He Song saw a group of black-robed cultivators fleeing in panic from the periphery of the Immortal Pavilion, desperately running toward the outside of the pavilion.
