btw my trick is exporting find slime girl or whatever im looking for fight then export it once find the name. then using game save notepad edit edit my moneys ive set to 10 mill. Then i go to slaver ah ive found that you can export almost everyone already exportered lillia rose scarlet and Ashley or aisha the haripe lady. I haven't been able to test it out since been waiting for replies but im hoping i can just breed traits i want. Ie have a slime girl daugter breed her then have succubus daughter then breed them both not sure if it will work but im hoping know about the milk stuff now might help
Well, first of all, only children you're directly responsible for are tracked to keep the save size down, so no hands-off slave breeding operations.
Second, the game doesn't naturally do hybridization, except for a limited form where slimes and demons can be the demonic/slime version of another race (which does include demons who are slimes and slimes who pretend to be demons. yes, there's a difference).
