Failed to Ascend, Took the System to Travel to the Demon World and Became the Demon King

As a proud man in the world of immortality, Lin Mu only needed 100 years to face the disaster of ascension. Originally, under everyone's expectant gaze, he suddenly became a god. Unexpectedly, a powerful purple thunder broke through Lin Mu who had already cultivated a golden body. In the end, Lin Mu only heard a horrified voice coming from below: "Purple Thunder, a rare sight in a thousand years!..." I also didn't notice the last sentence, "Whoever receives the purple thunder will become a king!" … Opening his eyes again, Lin Mu looked at the face that was exactly the same as in his previous life, and felt relieved that it was not ugly at all. It's just that the identity is a bit complicated, the descendant of a demon and a human. This is a shame in the demon world! What can be done? Of course, you can only conquer them by practicing hard. With the efforts of the system and myself, The fair-skinned and beautiful fiancée who was once forced to break off the engagement said: "Brother Lin, this is the dessert I made, you can try it~" The wolf demon who bullied him lay at his feet and begged for mercy, "Let me go, I'm willing to be your dog." The old demon king decreed, "If you marry my daughter, the demon king's position will be given to you!" "No, it's not rare! Since I can't become a god, I will become a devil." "Long live the devil!"
