I Am the Blade Saint: I Can Slay Every Foe in the World

An overpowered story with a brisk plot and no unnecessary dragging;

The protagonist has a treasure-hunting skill and can grow stronger by killing powerful enemies and taking their life force.

What?

You need to comprehend the world before you can advance in martial arts?

You also need to study and train hard to master martial techniques?

Why don’t I need to do any of that!!!

Watch as the protagonist, wielding a stone knife, rampages through an entire high-martial alternate world.
