Becoming The Strongest With The Crest Of Nothing

VRMMORPG sensation "Crest Online".
Commonly known as "Cleon", it's an action game where players wield their chosen crest as weapons during character creation, battling various formidable enemies.

Having held the top spot in the world rankings in Cleon, I suddenly found myself reincarnated one day, a thousand years into the game world's future.

Reborn as Zelos, the second son of the Marquis Sylphid family, what I received was the Gift everyone scorned as "useless" - the "Crest of Null".

Disappointment from my family, ridicule from my older brother. Amidst all that, I, possessing memories and knowledge from my previous life, alone knew.

This "Crest of Null" was in fact the "ultimate talent" capable of mastering all skills.

Utilizing gaming knowledge and the "Crest of Null", I rapidly acquired power at an astonishing pace. Eventually, armed with power surpassing even my previous life, I proceeded to overwhelm everything in this world.

What does it mean to be the strongest?
