Guarding the Demon Sect Saintess? I Gain a Year of Cultivation Every Day

In the final years of a dynasty, eunuchs hold power, and the demonic sect rises… In this chaotic world of demons and monsters, Chen Ran transmigrates into a powerless prison guard. Fortunately, he awakens a cheat ability: 【Heavenly Prison Scripture】 【Guard the Heavenly Prison for one day: Reward — one year of cultivation】 【Guard the Old Demon Xuanming for fifty years: Reward — Heavenly Demon Disintegration Technique】 【Guard the True Dragon of the demon race for eighty years: Reward — Indestructible Dragon Body】 Chen Ran originally thought he would lie low in the Heavenly Prison and slowly grow stronger. But he is suppressed by his superior and forced to guard the Saintess of the demonic sect, where the slightest mistake could cost him his life. Deep within the Heavenly Prison, cold winds howl. 【Name: Jiang Mengli】 【Realm: Fifth Rank (heavily injured, sealed)】 【Life Experience: Remnant of the former dynasty, fled and became the Saintess of the Red Lotus Demonic Sect, later accidentally imprisoned here…】 Chen Ran looks at the peerless beauty staring at him with killing intent, and curls his lips: “Your Highness, you wouldn’t want your secret to be known by others, would you?” … Through the long years of immortality, storms rise across the martial world. Whether unmatched geniuses, tyrants of the demonic path, supreme demon lords, or reincarnated great powers… As seas change and ages pass, I alone stand unmoved!
