Skills? Weapons? Even trash? As long as he gives selflessly, the rewards return a thousandfold.And so, while the world expects a humble philanthropist, Ethan casually breaks the balance of power, amassing wealth, strength, and influence—all while doing as little work as possible.Because, after all…Why struggle when generosity makes you overpowered?
