The Yandere Demon King Has Become My Full-Level Support

Feng Ranran is a working female ghost who makes a career out of scaring people. She has been in the industry for thirty years and is a veteran ghost. Boss: "What is your dream?" Feng Ranran: "My dream is not to work! I want to be reincarnated as a human being!" Boss: "Okay, if you make enough money, you will be reincarnated!" However, the boss unexpectedly disappeared. ——You have to rely on yourself for reincarnation! From then on, Feng Ranran embarked on the road to rebuild Yuanyuan (the reincarnation machine), and on the way encountered the demon king Zangqing who was extremely powerful. The demon king was so sick that he massacred the city when the neighboring country cut down a few trees on him; killed the giant gods when they blocked his way; and also speculated on real estate (housing where ghosts live). However, he begged for nothing and insisted on following Feng Ranran. He was determined to be a support, but he couldn't be driven away and couldn't be beaten. ——Is this a love debt during my lifetime? Or is it a fate after death?
