As the old man was shouting, the black fog surrounding his body was roiling like boiling water.
All of a sudden, the air current began to compress, and the sound of air explosion reverberated.
Moreover, a gust of invisible airwave swept out and transformed into gusts of majestic and strong winds that blew in every direction when the air explosion sounded.
The plants and trees in the forest shook with the old man at the center. Birds that perched on the trees flew away one after another from the shock and disappeared into the sky.
'Whoosh!'
It was unknown when a black silhouette appeared in the air above the mountain range.
"This semi-finished product doesn't look too bad… But he's still clinging on to old grudges. I'll need to work on him a little bit more in order to completely control him," the black silhouette muttered to himself, it seemed like he was dissatisfied.
