The Skill Effects Are Spectacular, but the Damage Is Zero?

Yang Sanyue transmigrates to another world and awakens the strongest skill around. Its special effects are MAX-level, but its damage is zero...

Whenever he chants a spell, his enemies see a world-destroying divine punishment. In reality, he can't even kill an ant.

But that doesn't stop him from putting on the air of a peerless master and calmly saying, “Kneel, or be reduced to ashes.”

Watching the Demon King's army fall to its knees, Yang Sanyue smiles.

Just when he thinks he can settle down and build a harem, he discovers that the beautiful women around him, the elven queen, the dragon princess, and the abyssal witch, could each crush him with a single finger.

Now here's the question... How can he keep up the act with these top-tier powerhouses surrounding him?
