Such a method was possible thanks to his mysterious and powerful Proficiency Panel. Anyone else, even a single system, would struggle to keep going, let alone two.

In the midst of his cultivation within the Fairy Pavilion, he suddenly opened his eyes, stood up abruptly, left the pavilion, and looked to the northeast.
He saw three colossal Immortal Castles, rolling in from the northeast, despite the endless distance separating them.
These three immensely vast Immortal Castles were not the conventional ones found in the Outer Domain Void battlefields, but rather were part of the one hundred and eight giant castles from the expedition to the Wisdom Realm two hundred years ago.
At the same time.
Two terrifying presences emerged from two different areas of the Celestial Heavens within the Immortal Court.
In an instant, light began to flicker throughout the entire Immortal Court, rising and coalescing into an Array so dense it was beyond imagination.
