Transmigrated to a World of Magic, but I Only Know Physical Attacks

Rayne transmigrates to a magical world, only to become a Muggle who can't use magic. Fortunately, he has the help of a System. But what on earth is this invincible muscle-enhancement System?

Maze Trial: While everyone else is struggling against all kinds of monsters and magical beasts with their magic, Rayne blasts straight through the maze with his biceps magic, clears it with ease, and claims his reward.

Ancient Ruins: While the archmages are being brutalized by a hellhound, Rayne uses his triceps magic to smash a demon god and make him kneel and call him "Daddy."

In a duel between gods of magic, Rayne says, "If I flick my little finger, you might all die!"

Countless years later, Rayne, who became a god of magic through muscle magic, looks at the demon gods and holy archmages trembling on their knees below and lets out a sigh.

"An invincible life is just so plain and dull..."
