Logically, even if these cultivators were swallowed by quicksand and fell into the depths of the earth, with their strength, they should have been able to escape and return to the surface.
But the Nine Heavens Profound Ascension Great Array, a sixth-order formation, was designed to deal with a large number of cultivators' ascension and therefore placed extra emphasis on defense.
When the ground collapsed, it altered the layout of the formation, turning a system that should have been outward-facing inward! As a result, countless cultivators were trapped inside the Great Array.
Without spiritual energy, they exhausted all their pills that could restore mana and still failed to break the formation.
Li Zhirui also saw in the Jade Slip that, after the pills were depleted, high-level cultivators forced low-level cultivators to attack the Great Array with their flesh and blood.
