I don't remember much details about it. Just that the kid is something like a genius, and a training maniac. The setting is a school/sect. The things I remember include some kind of training technique a teacher passes to his class, something like moving like a snake, the friction causing the skin to toughen, become flexible, etc. Teacher is a good guy since he encourages the others instead of putting them down after the MC went into training mode and made a 'dance' from the movements of the snake-training thing. Hope someone knows It's relatively lowkey I think. Last time I read it, I think it had around 28 chapters, so not a lot of chapters done. Thanks in advance
