For the subsequent classes, everyone had become a little absent-minded.
Xia Xibei's looks alone had given them enough to worry about, but no one had expected her competence to be so nerve-racking too.
Those who had thought that their voices were great fell silent the moment Xia Xibei started singing.
It was clearly the same song, but why did it sound so different when Xia Xibei sang it?!
They were left with no strength to retaliate at all!
Xia Qinghan's face had turned very pale.
Never in a million years had she expected Xia Xibei to have such a great voice!
She had thought that Xia Xibei was bound to embarrass herself in front of everyone, but who would have seen her splendid show coming?!
As she recalled Xia Xibei's performance, her nails dug deep into her palms, to the point that they almost drew blood.
Luckily, everyone's attention was focused on Xia Xibei at the moment, so no one noticed her unusual behavior.
