A Rare Treasure Appears on Blue Star, and I'm Somehow the First Challenger

I was an utterly ordinary freshman, heading to class on an utterly ordinary morning, when Blue Star underwent a sudden change. Somehow, I became the first challenger. I faced each challenge with brains and courage, but Blue Star was changing too. Only in the end did I learn that an invasion from other worlds had awakened Blue Star's self-preservation instinct. It selected guardians from among countless humans. This book is about how Blue Star, in its effort to protect itself, uses energy to create all kinds of challenge spaces. The protagonist, Wang Yi, has the power of thunder. His first form is blue, basic thunder. His second form is the Thunder Blood Lotus. His third form is the Darkest Thunder Punishment.
