Yu Qiang Ze Qiang, Wo De Xiu Wei Wu Shang Xian

Ye Lingjun, on the verge of death, awakened the Strength Through Adversity System, which marked the start of his unlimited cultivation ascension. Immortals, saints, and Taoist masters? They all better stand aside! To build a following, he picked up a few disciples. The eldest disciple was once the leader of the demonic sect. He may seem vicious and rebellious, but he soon becomes tamed. The second disciple is a white-haired loli, blessed with the perfect saintly constitution. She could become the strongest of them all, but she loves to cook, and she'd rather serve her master a fancy meal instead!
