Isekai, self-insert MC, space empire, overpowered, do I need to say more? Oh right, I use Chat-GPT for this, just dump a bunch of ideas in, copy the barely coherent mess and paste it here. This is for anyone who see all of that and are still interested: I want to make a novel with as realistic physics as possible. I will, almost definitely, create a bunch of magical sci-fi stuff, especially later on, but I will try to stick to established rules as much as possible. Much of the orbital mechanics and warfare is learnt from the game Children of a dead Earth and Kerbal Space Program. This is my very first book, so expect no planning and shitty execution, even with GPT.

What would you do if, on your deathbed, you were offered one last game? Would you choose a grand adventure? A tale of romance? A world to rule? Kayle made his choice—an adult game. A game he never got to experience in his first life. But instead of indulgence, he wakes up at rock bottom—a lowly servant boy in a crumbling brothel, trapped in a city on the brink of ruin. His goal remains the same: to enjoy the story he never got to play. Unfortunately, his very existence is already rewriting it. One day while walking through the streets of the capital city's slums, everyone suddenly bowed down to me. "Greetings! Godfather!" **** Disclaimer 1. "Is this a harem?" A common question from my previous novel, so I'll address it upfront. No, it is not. At least, not in the traditional sense. He'll have relationships with many girls, but most of them will be a fling. There will only be one final heroine. 3. If you decide to give my novel a try, first, thank you! Second, I would love if you could leave a few comments or a review. The feedback and confirmation that people are reading my book helps to keep me writing. 4. There is no smut in my book. I repeat, there is NO SMUT in my book. I know the title can be misleading, but I assure you, there is no smut in my book. (Important things should be repeated three times.) 5. I'm currently working on fixing my update schedule, but it should be sorted by March and will most likely be 3-4 chapters a week.
