As the old man's roar echoed, the dark fog wrapped around his body churned, boiling over like rolling water.
For a moment, the airflow in the surrounding air was completely compressed together, causing a series of thunderous explosion sounds.
Not only that, but as the explosive sounds rang out, waves of invisible air swept through, turning into a vast and violent wind that blew in all directions.
Instantly, with the old man as the center, the grass and trees in the nearby forests shook, and the birds that had been perched on the trees took off in fright, disappearing into the high sky.
Whoosh!
When no-one-knows-how, a black figure appeared above the mountains.
"This 'half-finished product' seems not bad... However, his 'obsession' with hatred makes it slightly more difficult to completely control him."
The owner of the black figure murmured, seemingly a bit dissatisfied.
