Badgirl

They called him a cripple. They called him a servant. They called him the most worthless man alive. Alex Vex has no magic. In a world defined by flashy elemental spells and cultivation ranks, he is forced to live as the disposable, live-in son-in-law to the prestigious Lin family—a necessary evil to shame their talented daughter, Lin Mei. To humiliate him further, they enroll him in the Silverpeak Battle Academy, expecting him to be crushed in the lowest tier, Class F. What they don't know is that Alex is not a man of this world. He is Subject 001—the last functioning super-soldier, the "Man-Made God" from the long-dead Aethelian Empire—a civilization that mastered physics, bio-engineering, and kinetic efficiency far beyond this world’s petty magic. When a Level 50 Fire Dragon attacks the campus, the mages scream and prepare their grandest spells. Alex? He sees a flawed biological weapon with seven weak points and a ninety-second expiry date. The world believes they are preparing to sacrifice their useless son-in-law. Alex is simply waiting for them to show him their necks.
