What Do I Do After Reincarnating as a Short-Lived Demon Lord? Help!

Shi Jian transmigrated into the world of cultivation, computer and all, and became the notorious, bloodthirsty, cruel, powerful, and universally despised supreme Demon Lord, Shi Jian!

Becoming a Demon Lord was bad enough, but the original owner was vicious and brutal, guilty of countless evil deeds, and had enemies all over the world! Not long ago, she had even caused a major incident, forcing the forces of good and evil, sworn enemies though they were, to break their vows and join hands to kill her!

Now, although she had come back to life, her cultivation was sealed, she had no one to rely on, and she had to be on guard at every turn to keep people from recognizing her.

Poor Shi Jian could only cry like a little cat.

What should you do when you transmigrate into the body of a short-lived Demon Lord?

Should you cripple your cultivation and start over as a righteous immortal maiden? Or live under an assumed name and quietly lie low until ascension?

Or change your face and become a kindhearted, beloved, highly respected, thoroughly good person?

Answers welcome. I'm in a real hurry!
