“Chu Fei, why have you grown so quickly despite losing both your parents and having no family to support you?!”

Chu Fei laughed loudly. “Because I have perseverance and work hard.”

“Chu Fei, how can you recover instantly even after suffering serious injuries?!”

Chu Fei laughed just as loudly. “Because I have perseverance and work hard.”

“Chu Fei, why do you...”

“Will you quit asking me why, for fuck’s sake? Everything I’ve achieved today is thanks to my own perseverance and hard work!”

With that, Chu Fei raised his blade and brought it down. The world fell silent.
