Hey guys I’m trying to remember the name of an isekai where the mc reincarnates as a young boy who tames slime and uses them to clean and do other small jobs. The slimes would evolve and take on different attributes like becoming poisonous based on what they were fed. I vaguely remember the mc having a sad backstory. The cover was mc, a slime, and some townsfolk. It was being updated frequently a couple years ago i think (i have a terrible concept of time). Thats about all i can remember, thanks to anyone who replies.
