Within this vast, boundless underground lava chamber, the black sphere had already been taken away by Leo.
He had even taken away a large amount of lava and ground along with it, creating a vacant space of roughly 100,000 cubic meters across the entire area.
However, as Leo withdrew his spatial domain, that enormous empty space was immediately filled by countless streams of lava.
The resulting turbulence even caused the surrounding aura to grow several times denser.
The disappearance of roughly 100,000 cubic meters of space, along with the massive amount of lava that vanished, was merely a drop in the ocean to the entire underground chamber and could almost be ignored.
Instead, the sudden spatial disturbance caused the entire underground chamber to grow somewhat restless.
Although the small black box had already been churning the underground lava chamber in a strange manner, the affected area was not large. It had merely expanded outward from a single point, but the impact was still enough to disturb nearly half of the underground chamber.
However, the sudden disappearance of that enormous space caused the lava, already under immense pressure, to surge inward, directly triggering a considerable explosion where it had been.
The impact was enough to make the previously rather tranquil lava chamber become completely agitated.
At this moment, as the lava across most of the chamber gradually grew restless, the pressure throughout the underground chamber also began to rise rapidly.
However, the increase was limited. Although the pressure was rising, it would not increase that rapidly.
This still gave Leo ample room and time to manipulate the situation.
But the surrounding lava was no longer as it had been when Leo first descended.
Now, empty bubbles were rising all around before bursting one after another, while intense heat continuously spread outward.
