King Kai, watching from the side as Goku unleashed the fourfold Kaio-ken, immediately darkened and hurriedly shouted for Goku to stop.
But Goku, desperately craving power, paid no heed to King Kai's warning. He stubbornly pushed that terrifying, violent power to its limit.
"Yaaahhh!"
His power soared in an instant, accompanied by intense pain. Whether it was the exhilaration of gaining power or the violent tearing agony in his internal organs, Goku's roar only grew louder.
Boom!
The shockwave suddenly swelled, the beam's arc surging as its might rapidly increased. It crashed toward Uchiha Hikaru—and the wall of light before him.
Watching the beam constantly advance toward him, Uchiha Hikaru's smile curved even deeper. The grin on his face grew more pronounced, yet he remained as calm as ever.
Uchiha Hikaru's smile carried a mocking edge. With a thought, an immense repulsive force suddenly erupted from the barrier, instantly bouncing the beam back!
"What?!"
Watching the beam get flung into the distance, Goku cried out in shock.
The beam was knocked far away, streaking into the sky and beyond Kai Star. It seemed to collide with some planet, followed by a sudden earth-shaking boom.
The disturbance was immense. Beyond the Milky Way, the beam's power directly destroyed a planet. The explosion unleashed an incredibly powerful blast wave, sending ripples spreading outward beyond the galaxy.
Feeling the fierce wind rushing toward him from atop Kai Star, Goku's heart was already churning with towering waves of shock.
It took Goku a while to calm down. Fixing his attention on Uchiha Hikaru, he muttered, "This guy's abilities are strange. Against my attacks, he only dodges and defends. That makes it impossible for me to figure out his true strength."
Whether it was his speed or defensive ability, the strength Uchiha Hikaru had displayed
