Now a novel and manga!

The Tower of Heavenly Descent, a mysterious dungeon where each floor is as vast as a continent.

Humanity, on the brink of extinction due to cataclysms, barely managed to survive by utilizing items from the Tower of Heavenly Descent.

In that tower, there was a Sword Saint known as the strongest.

He reached the unexplored seventh floor—and then hit Level 99.

He could no longer grow stronger.

However, the Sword Saint had one last resort.

To reincarnate while maintaining his Level 99 stats, and start over from Level 1.

But the reincarnated Sword Saint was met with pitying glances from his new family.

"Poor thing. Of all things, the 'Mark of Incompetence'..."

The Mark of Incompetence? What's that?

No matter how you look at it, it's clearly the strongest 'Mark of Limit Break'!
