Strongest Side-Character System: Please don't steal the spotlight

"What? I just need to keep presenting myself as the strongest side character to the main character and the other side characters in this novel in order to become the literal strongest within it?"

Vonjo was just heading to work when the ground collapsed beneath him—and he fell into an abyss.

When he awoke, he was inside a novel… reborn as a nameless sorcerer from one of the most powerful and ruthless clans in existence.

There’s just one problem: he’s completely average. In a clan that worships strength, that makes him worthless.

Cast aside without hesitation, Vonjo spends years surviving in obscurity—until the clan suddenly summons him back. Not out of trust, but because they need a disposable pawn for a suicide mission.

But everything changes when he crosses paths with the story’s true protagonist.

A system awakens.

The Strongest Side-Character System.

Its rules are simple:
Show yourselr as the strongest.
Make others believe it.
Earn daily rewards.

Vonjo doesn’t need to become the main character.

He just needs to convince the world he’s already the strongest.
