A Benevolent Mage? No, a Physical Menace!

An Xin, a once-in-a-century genius with an enormous mana pool, stunned the entire An clan. His innate mana was maxed out, but he awakened a talent that made it impossible for him to learn offensive magic: [Benevolence]. Effect: Cannot use any offensive magic. Buff effects are massively amplified! The whole school mocked him. “A super healer with nothing but a huge mana bar!” “The An family's a bunch of brawlers, and now they've got a healer? That's even more ridiculous than his father, the magic nerd!” Even An Xin was baffled. With my family's inherited fighting spirit and this primordial mana, am I really supposed to spend the rest of my life buffing people and healing my teammates? Weren't I supposed to smash forbidden spells with my fists and kick the elements around?! But when his innate magic appeared in his spellbook, An Xin smiled. It was none other than his family's own signature spell, dubbed the “humanoid beast-making machine”: [Mana Unleashed]! And its proficiency was already maxed out from birth! A wild idea exploded in his mind: Can't attack? Then I'll just stack buffs on myself and teach you all a lesson in physics~ And so, mages around the world began to have their worldview rewritten: “Referee! He tanked my Fireburst spell with his bare body! Is that allowed!?” “Help! Why is a healer charging at me!? Wait, why can't I use magic anymore!?” “Quick, stop that healer! Don't let him get over here!!!” “And watch out for his teammates! Stay away from that girl who blows up everything she touches!”
