I'm a Ghost-Controller, and the Fox Demon's Wife Is Too Clingy

[Single female protagonist + pure love + no system + cool writing + supernatural style + not scary] Li Yufan never expected that he, a newly graduated college student, would actually enjoy the treatment of King Zhou. A beautiful fox demon who had cultivated into a human form actually cried and wanted to be his wife! "Ms. Sir, are you hungry?" "Mr. Sir, I have reached the legal age for marriage. When will we get a marriage certificate?" "A gift of 388,000 yuan? No, our Fox clan doesn't pay attention to that. Even if we have it, I'll just give it to you for free!" As the saying goes, good things come in pairs. Not only did Li Yufan get a fox demon wife, he also successfully awakened the evil spirit and became an underworld agent who drove ghosts to do things for the underworld. "If you want your daughter-in-law to conceive a grandson, if it's easy to talk about it, I'll carve a statue of Guanyin for you to give birth to a child." "You want to protect yourself and perform well in the college entrance examination. This is simple. I know Wen Quxing very well!" "What, you want to ask about this lottery number? I'm tricking you, you can't control the cause and effect!"
