I recommend the novel "Law Enforcement System of the Other World" to you. The main character of the story, the ruthless Zhu Qingbai, was bound by the law enforcement system of the other world and was forced to transmigrate to various other worlds to complete the task of law enforcement. In the novel, you can see the appearance of the Ryong family, the use of exorcism wands, and forced labor. It fits your description very well. I hope you like my recommendation, Mwah ~π
