Burning Lifespan to Simulate: I Rampage Through a World of Demons

He transmigrates to another world overrun by demons and monsters, becoming the useless son of the bandit chief of Blackwind Stronghold.

Lu Yuan activates the Lifespan-For-Insights System: spend years of his life to instantly deduce any technique to perfection!

Kill demons and monsters to obtain demonic lifespan, then burn that lifespan to strengthen himself. Using other people's lives to cultivate his own immortality: that's what you call having vision.

From then on, Blackwind Stronghold's style changes completely:

Others toil for ten years to master a technique; Lu Yuan takes a moment in seclusion to perfect an Heaven-Tier technique.

Others turn and run when they meet a monster; Lu Yuan gives chase for three thousand miles, blade in hand: "Don't run! You're all extra years for me!"

The imperial court offers amnesty? The sects try to recruit him? The Demon King provokes him?

Lu Yuan has just one principle: spending lifespan is fine, but not mine.

When Blackwind Stronghold's banners fly across the Nine Provinces, and the mighty of the Three Realms kneel at his feet, someone asks Lu Yuan how he did it.

He glances at the 80,000 years of life he still has and smiles calmly:

"Maybe I'm just good at cherishing my life."

No female lead. No idiotic characters. Decisive and ruthless. A power fantasy fueled by lifespan. Kill demons for years of life, deduce all techniques. In this life, my fate is mine, not heaven's, nor the demons'!
