Dragon Slaying Jelly

In the era of beasts, everyone becomes a demon at the age of 18. I was originally recognized as a mediocre talent, but when I awakened, I summoned an S-class golden dragon. I was then falsely accused of stealing it, and the dean expelled me without distinguishing right from wrong. Fortunately, thanks to the god-level selection system, I gave up the golden dragon and obtained the SSS-level god slime - which can transform into various forms and learn various skills. I entered the wilderness for training and upgrading, captured young tigers as companions, and step by step climbed to the top of the beasts with the weakest slime.
