Haaaa!!!
Joan dashed with all his might. This time was a little bit faster. Pushing himself to the limit will only hasten his growth. Knowing this, he used his strength more than before. Keeping his speed rose higher and higher, his dexterous movements were pushed to the limits.
His vitals were expanding, making his vitality rose. The focus was on its limits and was expanding his mind's capacity. He was undergoing monstrous growth while pushing his all. It was called none other than [Stat cultivation]. A skill that Joan created when he was training the heroes since their young selves and other students on the academy.
[Stat cultivation]–a passive skill of Joan that will become active once one's limits were pushed to the brim. Further increasing his stats when he was doing exercises or when getting all out. The skill was on its highest level as Joan comprehended it in the past. Etching the very skill upon his soul.
