The pitch-black void, the pitch-black umbrella, the pitch-black tip of the umbrella...
Like a lightning bolt, a black color suddenly flared in the void, causing the entire plane to emit a trembling moan. Boi, having fully unleashed his combat power, had reached the level of a Main God with this strike; it surpassed the endurance of this plane. Wherever the black flash passed, space crumbled inch by inch.
In this strike of Boi's, there was not the slightest bit of flourish, he didn't even use a fraction of the Illusion Technique he was most skilled in.
