Xuanhuan: You Spend Your Lifespan, I Get Stronger. Seems Fair, Right?

This blurb really isn't doing the story justice. Go read the main text! A completely fresh concept, and if you don't enjoy it, you can kill me!

Jiang Yun transmigrated into a fantasy world where the strong ruled, and awakened the strongest life-for-power System.

Everything in the world changed.

"Junior Brother, you're just one step away from breaking through to the Qi Movement Realm? I have a Breakthrough Pill here. All it costs is five years of your life!"

Congratulations, Host. One year of lifespan spent. Breakthrough Pill successfully redeemed!

"My friend, your bones are rather poor. I have a top-tier Sacred Physique here. All it costs is a thousand years of your life!"

Congratulations, Host. Five hundred years of lifespan spent. Thunderclap Sacred Physique successfully redeemed!

Many years later.

Jiang Yun looked at himself, with his infinite lifespan, and fell into deep thought.

"You spend your life force, I get stronger. That's perfectly reasonable, right?"

I let my guard down. I ran into a truly bizarre Host!
