(The author is new to writing, so please forgive the rough style and weak prose. Feel free to drop the book if it isn’t for you, but the concept is definitely solid. Mostly infinite-flow, with one female lead.)
The chuunibyou teen Bai Ying encounters a battle evaluation System: the more exhilarating the fight, the greater the reward. As time goes on, Bai Ying learns what kind of world he is living in. He grows more mature and levelheaded, though he can’t shake his chuunibyou habits. Eventually, he finds his guiding principle and officially sets out on his journey.
(Just so you know, if this book turns out well, there’s a chance I’ll write a sequel.)
