Lu Jia transmigrates into a world where everyone can use magic.
On the day he awakens his powers at sixteen, the entire school laughs at him: what he summoned is a shabby stone the size of his palm.
No one knows that the stone can grow.
And no one knows that the cheap street-market bracelet nobody wanted, wrapped around his wrist, will turn into two guns that should not exist in this world when he recites an incantation.
Fireballs take three seconds to cast. His bullets take just 0.3 seconds.
Mages all over the world chant their spells. He just draws his guns and fires.
Until one day, he looks up and sees a meteor crashing down from the sky
