Slay Demons to Steal Their Lifespan, Prove the Dao with My Life

Killing demons grants lifespan, and the lifespan gained can be used to deduce cultivation techniques.

On the first day after transmigrating, Li Jie encountered soldiers conspiring with demons to surround the mountain. His father was gravely wounded, the stronghold was about to fall, and Li Jie had only three years left to live.

He activated the Life-Burning System.

Spend one year of life to deduce his saber technique to mastery. One slash kills a demon and steals thirty years of its lifespan.

Spend ten years of life to deduce a cultivation technique to perfection, break through four realms in a row, and slaughter the soldiers until not one remains.

Spend a hundred years of life to deduce a forbidden art to its ultimate level, kill a demon general despite the difference in cultivation, and shock the entire Myriad Demon Mountain.

From then on, Li Jie walked a path of no return:

Other people cultivate through talent and resources. He cultivates by burning his lifespan.

When the Seven Great Demon Saints joined forces to kill him, Li Jie looked at the million years of tribulation he had accumulated and smiled:

"Do you know how I made it through this million years?"
