The Strongest Top-Up Mage

Born with zero mana, Nova Shadowtear is mocked as the weaakest mage alive-until her fiancé humiliates her and breaksoff their engagement. At her lowest point, a mysterious pay-to-win system awakens, letting her buy impossible powers and crush anyone in her way. But as Nova rises from outcast to unstoppable mage, she discovers the system hides a far greater secret: she may be the chosen heir to the Creation Goddess-and the conly one who can stop an ancient darkness from consuming the world.
