I also wrote My Undeath, a reincarnation novel set in a fantasy world. It wasn't my best work, but I loved writing the story.I put a lot more time and effort into Reborn with a Necromancer System, and ironed out the details for a while, plotting approximately 500 chapters for all of you. If you liked either of my other two novels, this novel has a lot more planned for it than the other two.
