Immortality: Starting with Adding Points to Mortal Cultivation Techniques

Gu Qingshan transmigrated into the body of a lowly jailer in the Heavenly Prison. In this chaotic world where human life is cheap and demons run rampant, Gu Qingshan only wanted to live a quiet life until the end of time. Fortunately, he awakened the Longevity System, granting him unlimited lifespan and the ability to gain one attribute point every year! While peerless geniuses fought tooth and nail for a single martial arts manual, he was quietly adding points to "Iron Shirt" (a martial arts manual). [Iron Shirt] +1, promoted to Bronze Skin! [Iron Shirt] +1, promoted to Iron Bones! Iron Shirt +1, Golden Body Perfection! What? Ordinary martial arts can "break limits"? Breaking the limits! Awakening [Shockwave Counterattack]! Dare to touch me? Before I even throw a punch, your divine weapon will shatter into dust! Inside the Heavenly Prison is a cannibalistic world; outside the Heavenly Prison is a court where gods fight. The White Lotus Demon has transformed into a flesh and blood lotus, terrifying and bizarre! Powerful ministers vie for power, and princes fight for the throne; a single misstep can turn one into cannon fodder! Faced with all this, Gu Qingshan chose to—play it safe! Play it safe even more! Play it safe to the extreme! Trying to get me to take sides? Sorry, my old ailment flared up again, and I collapsed on the spot. Are you trying to force me to take the lead? Sorry, I'm taking leave tonight and going home to avoid trouble. With his unparalleled skill in "playing dead" and absolute low profile, he outlived one after another his enemies, superiors, and even the emperor! A century later, when former enemies turned to dust, when the supreme dynasty fell to ashes, and when the lifespan of the once invincible cultivators ran out, Gu Qingshan remained young. He walked out of the prison, looked at this brand new world, and smiled slightly. "You fight for your eternal reigns, I, being immortal, will take responsibility for sending you all... on your way!"
