Struggling to Survive with Regression Power in the Primordial Saint Sect

L Yang transmigrated into the Cultivation World and became a disciple of the Demon Sect, the Primordial Saint Sect.Fortunately, he obtained the mysterious treasure Book of a Hundred Lifetimes, which allowed him to restart a new lifetime after death, letting everything begin anew. He could even bring back treasures, cultivation, lifespan, and might even awaken special talents from his previous life.However, the number of uses was limited; it did not grant true immortality.As the Cultivation World was on the verge of chaotic times, L Yang had originally decided to lie low in the Demon Sect, cultivating painstakingly through one lifetime after another. He would not leave the mountain unless he achieved immortality. Yet, the Demon Sect was extraordinarily perilous, and talents were everywhere.In the first lifetime, L Yang suffered a forced assault and was directly overexerted to death by his Senior Sister.In the second lifetime, L Yang seized power from below and overexerted his Senior Sister to death, but still could not escape the deadly hands of his Senior Brother.The third lifetime The fourth lifetimeUntil after a hundred lifetimes, when he looked back, L Yang realized that he had already become a Great Overlord of the Demonic Path, the most beastly existence within the Primordial Saint Sect."The Demon Sect is truly full of talents, and they all speak so nicely.""I really love it here!"
