[Supernatural Martial Arts] + [Overwhelmingly Invincible] + [Blood-Pumping Power Fantasy] + [Decisive and Ruthless] Primordial power awakens, and martial arts rise! Jiang Feng transmigrates to a high-martial world where martial arts reign supreme. He serves in the army for thirty years, defending against the myriad races and surviving battle after battle without ever abandoning his original ideals. Unfortunately, his talent is too poor for him to make any progress in martial arts, so he leaves the front lines and becomes a retired veteran. He thinks this is as far as his life will go, but on his hundredth birthday, he activates the [Kill Enemies to Level Up] System. Every enemy he kills makes him stronger, and from the start, he gains a god-tier talent: Heaven-Defying Comprehension! Any cultivation technique or divine ability comes naturally to him, without a teacher!

Witness how this hundred-year-old veteran stirs heaven and earth and stands at the forefront of a magnificent, dark age! I am the nightmare of the myriad races across the heavens! P.S.
