Synopsis

The protagonist, struggling to complete a task and on the verge of collapse, finds a small mana stone. Upon consuming it, he experiences a surge of mana, realizing it's another chance similar to his time regression. This mana boost reignites his determination to overcome his weak mana veins through physical training described in a grimoire he discovers, contrasting his previous life focused on theory. He also has a brief, supportive interaction with his professor who then assigns him a difficult task, yet the protagonist is not deterred due to his past diligence in theory.
