I don't know which novel 'Back to Earth as a Trickster' refers to. However, generally speaking, whether a novel was updated or not depended on the author's work plan and inspiration. Some authors might update their works frequently, while others might prefer to stop updating or update slowly at certain times. I can't give an accurate answer to the specific reason why the novel 'Return to Earth and Become a Trickster' is named. If I can provide more specific information, I will try my best to answer your questions.
