With a thought, he let the Attribute Board begin to upgrade the Black Hole Profound.
In an instant, the Attribute Board flashed violently. A terrifying and strange force surged into Chu Zhou's body and continuously modified his body and soul.
At the same time, countless comprehensions about the black hole appeared in his heart.
His understanding of black holes improved by leaps and bounds.
"Rumble—"
A terrifying devouring power suddenly came from his body.
Under the effect of the devouring power, the meteorite under him instantly turned into dust.
Then, the space around him began to distort and collapse.
Soon, a black hole with a diameter of more than ten meters appeared.
Then, the black hole expanded at an astonishing speed.
100 meters!
1,000 meters!
10,000 meters!
100,000 meters!
…
The black hole became even larger than Earth.
