I Only Hit You with an A, and You Open with Your Ultimate?

Ye Yuan transmigrates into a high-martial world and awakens as a Forbidden Spell Mage. Unfortunately, he can only cast one forbidden spell in his entire life.

Just then, a beast tide attacks the city. To protect his family's safety, Ye Yuan steps forward and unleashes the forbidden spell, Red Lotus Flame Rain, averting a deadly crisis.

Who could have guessed that instead of being grateful, his family would covet the credit for his heroic deed in saving the city? They force him to hand the honor of casting the forbidden spell over to his eldest brother.

"Fine! If you're all shameless enough to do this, why should I keep hiding my abilities?"

"Who says a Forbidden Spell Mage can only cast one forbidden spell in a lifetime?"

When Ye Yuan starts using forbidden spells as casually as basic attacks, the Ye family members weep with regret, realizing their mistake.

"No. Only the living have the right to admit they've made a mistake. You... aren't you already dead?"
