Ma Daqiang is a classmate sitting next to Chen Yu in math class. He is initially drowsy but becomes alert when he sees Chen Yu suddenly perk up. He silently comments that Chen Yu must be a pervert for liking math. Later, he notices Chen Yu sweating from body tempering during class and wonders if Chen Yu had bought magical power, hoping to get a cheap introduction to such channels. He is a minor character who observes Chen Yu's unconventional behavior.
