Cultivating Through Lifespan Deduction, I Advance Realms as Easily as Drinking Water

(Demonic cultivator, no goody-two-shoes hero, no female lead, cautious, invincible among peers, showing off, wish-fulfillment.) Chen Liu transmigrates into a fantasy world and obtains a Lifespan System. By scavenging the bodies of people who have been dead for no more than two hours, he can gain their remaining years and extend his own life. The System can also use lifespan to run simulations and deduce techniques. “What do you mean, the Nine Nether Demonic Art can only be learned by someone with a Heavenly Spiritual Root?” “Sorry, I may have a low-grade Yellow spiritual root, but I used a hundred years of lifespan to deduce the art and learned it in half an hour.” “You say the Nine-Star Tyrant Body Art can only be cultivated by someone with extraordinary willpower, and that reaching the minor mastery stage requires a Heavenly spiritual root and decades of painstaking effort?” “Sorry, I have a low-grade spiritual root, but I used a thousand years of lifespan to deduce it to minor mastery. It only took me two days in real time.” “What, you say divine and demonic arts can’t be practiced together, or the cultivator will explode?” “Honestly, sorry about that. I used ten thousand years of lifespan to figure out how to practice them together, and accidentally forged an unrivaled divine-demonic body.” Chen Liu surges ahead in the fantasy world. He shows off during the entrance exam and becomes the Demon Sect’s chosen heir. He shows off at the genius tournament, beating the prodigies of countless races into submission and winning the princess of an ancient cultivation kingdom’s heart. When an immortal from beyond the world tries to harvest the lives of the common people to increase his power, Chen Liu slaps him so hard he doesn’t even know his own name.
