The Immortal Genius Spearman

"In this life, I'll be the one who rules the battlefield." Damian, a centurion in the Baroque Kingdom's punishment unit, dies nameless on some forgotten front at the age of thirty, regretting only one thing: "Damn it... If I'd just had one more chance, I really would've ruled the battlefield with these guys." When he opens his eyes again, he's gone back seventeen years—this time with a perfectly intact mana core that actually lets him learn magic. This time, he swears, he won't be swept along by an age of endless war. He'll climb higher than anyone and become the one who dominates it. Reborn in the past, Damian raises his spear toward the world and begins carving out the future he couldn't reach before.
