This old man was powerful!
Qin Shaofeng's heart tightened, and his expression grew grave.
That Rasengan just now might not have been his strongest move.
But it had consumed half the World Power in his Inner World. How could the Rasengan it unleashed possibly be taken lightly?
Although he had never fought a true Emperor Realm expert before, Qin Shaofeng estimated that the Rasengan unleashed by exhausting half his Inner World's World Power would likely be something even an ordinary first-level Emperor Realm expert would not dare receive head-on.
An even weaker first-level Emperor Realm expert might very well be blasted into grievous injury by that move if they were careless.
Yet this old man from the Blade Demon Clan had actually shattered Qin Shaofeng's highly confident move with a single punch.
How could such strength merely belong to an ordinary first-level Emperor Realm expert?
Qin Shaofeng was filled with uncertainty, while the vigilance in his heart rose to its limit.
Because Qin Shaofeng knew very clearly that he had likely encountered an exceptionally terrifying first-level Emperor Realm expert!
At that very moment, the Blade Demon Clan's ancestor was equally shaken by stormy waves in his heart.
How was this possible?
Though he had shattered Qin Shaofeng's Rasengan, its power had left an indelible impression on the Blade Demon Clan's ancestor.
The Blade Demon Clan's ancestor had seen attacks a hundred times more powerful than that Rasengan.
But the issue was not the attack's strength—it was the human who had unleashed it!
Because the Yin and Yang sides of his Inner World's domains had begun to merge, Qin Shaofeng's domain could now produce an extremely special concealment ability through the fusion of Yin-Yang Power.
Even ordinary Nirvana Realm experts would find it difficult to detect Qin Shaofeng's aura and cultivation
