He had been outsmarted!
At this moment, Sparrow Bee couldn't feel more stifled. After all, he was a big shot who had lived through a Reincarnation, and though not immensely famous, he'd fared pretty well, hadn't he? At least well enough to force the Four Major Guilds to suppress him. If only he hadn't arrived so late, he felt that he would, by now, have a place among the top forces.
But now, he first got thoroughly humbled by a member of the Human Race who hadn't even lived for a hundred years, and now a young girl had frightened him enough to break a King Level seal. How utterly humiliating!
Yes, how could he not see it by now? The opponent had not broken through the upper limit of King Level, she had just employed some method that allowed her to approach him easily. To use gaming terms, she merely threw a tentative basic attack while he unnecessarily unleashed his ultimate move.
How embarrassing...
