As Long as Someone Remembers Me, I Will Never Fade Away

[Advanced martial arts + genius + no System + slow pace early on + nearly invincible]

After a thousand years of martial arts, the abyssal rifts have become a permanent fixture of the world.

Nine gates, like heavenly portals, have formed, bringing energy capable of changing the world, along with destruction and calamity.

The world has learned martial arts and martial techniques.

People fight against the demonic beasts that continually pour out of the nine demonic gates.

Eighteen Martial Sages lead everyone in holding back the demonic tide.

Then, for nine hundred years, no new Martial Sage appears. A century of flourishing martial arts proves to be little more than a surface calm.

The world tries to save itself, giving rise to people from other worlds, time travelers, simulation-space users…

All for the last sliver of hope.
