The Immortal Emperor Turned to Demonic Cultivation for Eternal Life

【Lighthearted comedy + System + slow-paced】 What do you mean, I transmigrated, the System gave me a top-tier talent, and then disappeared? Three hundred years later, I became an Immortal Emperor and the founding patriarch of the cultivation world’s greatest sect. Then the System suddenly returned and told me: “You can only cultivate the demonic path. Otherwise, you’ll die in ten days. Only demonic cultivators can live forever.” Ha! I, Lu Jiang, am a dignified Immortal Emperor. How could I possibly believe the nonsense this lousy System spouts? … Big Brother System, Great-Uncle System, I was wrong. I’ll switch to cultivating the demonic path right away.
