After transmigrating, law doctorate Qin Yun awakens with a dismally weak talent for magic. Yet by chance, he gains the ability to turn real-world legal concepts into an understanding of the laws of the world. He cannot cast a fireball, but he can interpret, amend, and even create magical contracts. He cannot wield battle aura, but he can invoke antitrust law to dismantle the monopoly held by the aristocratic mage towers. While every other mage pursues power, he uses intellectual property law to protect his arcane spells, company law to build a mages' guild, and criminal law to put abyssal demons on trial. In a world that worships strength, he will use the law to bring even the gods before the bar.
