Capítulo 509: None of you should harbor the thoughts of running

It sounded like something vibrating at a speedy pace. It was a sharp sound emitted from the friction of air that nearly burst the eardrums of many.

The crowd traced the source of the sound and looked over.

In a corner, a girl with a single pigtail was looking at them in a deadpan manner. She held two pieces of metal in her hand and they were vibrating rapidly, grinding against each other to emit the sharp, ear-piercing sound.

The girl had bright eyes and beautiful teeth. She looked gorgeous and exuded a pure and youthful air. She was much more beautiful than so-called school belles.

But in the eyes of the upper echelons of the various organizations, the girl was like a devil. She was emitting a sharp sound that left them dizzy. It was unbearable!

The members of the upper echelons covered their ears as they hurriedly ordered the girl to stop.

The girl remained expressionless but she did not stop.
