I wrote this article for a netizen who commissioned me to write a novel. It’s a pity that after I wrote three episodes, he disappeared without saying goodbye. It’s a pity to leave this half of the article behind, because I read his initial design of the story, the characters and the plot are very interesting, and special ideas. But he just left without saying goodbye. I want to pick it up again, but I really have no motivation, and I don’t want to let this wonderful article remain silent in my article In the folder, I dare to publish it here. Please forgive me for various reasons. Finally, to this disappeared netizen said: treasure!
