As Fang Cheng continued to refine the six arrays, the Immortal Copper Treasure Box also began to change. Countless fine patterns materialized on its surface, with streams of flowing light coursing through them, looking as if it were about to crack open.
In that instant, Fang Cheng's divine soul passed through the Immortal Copper Treasure Box and suddenly plunged into a vast darkness.
Inside the Treasure Box.
Within the darkness, countless stars twinkled faintly, just like in the Outer Void.
In the distance was a massive, wildly spinning vortex, so deep it was unfathomable, seemingly capable of devouring everything.
A sudden understanding flooded Fang Cheng's mind, and all sorts of information about the Immortal Copper Treasure Box surfaced.
The Returning Ruins Vortex!
A legendary existence said to be able to devour all things in the myriad heavens.
