Longevity: Cultivating by Burning Through My Lifespan

Others spend money to grow stronger; I spend my life. Others practice martial arts; I cultivate immortality!

The world's martial artists are divided into nine ranks, yet even the weakest immortal can surpass them with a single finger!

Lin Yi transmigrates into a chaotic world overrun by demons and monsters, where he gains a Life-for-Power Cultivation System. By slaying demons and ghosts, he can obtain their remaining lifespans. He can spend those years to deduce techniques and accelerate his cultivation.

With the System's help, Lin Yi rises step by step from a lowly lieutenant in the Demon Suppression Bureau, ultimately reaching the pinnacle of the immortal path!
