Derivative Advance Collection/brain Storage Place

There are too many ideas, so I decided to put them in a storage place. New derivative ideas will be inserted directly in the future! By the way, I'm going to play the first chapter of some of the pre-released spin-offs for trial reading. I'll see which one I open when the time comes. You don't need to buy the nutrient solution from Leitou, you don't even need to save it~ As long as you leave a comment and tell me which book you want to read more, I'll be satisfied! (Thumb) Intention: open the door, samples are delivered!
