Looking up "slime" and "isekai" in the advanced search got me After Surviving the SSS-Rank Demon Territory With a Useless Skill, I Became the Strongest Alchemist in the World ~Creating a Comfortable Base and Enjoying Life With Friends in Another World~

Edit: Looks like I was late.

I'm a jack of all trades but master of none. Too many jars and not enough hands.

I looked up isekai, dragons, tamer, alchemist (the correct tags for getting results) and came up with nothing

thanks to both of you
