He gets stomped on by his dragon mother but it's fine because her magic is almost omnipotent and can resurrect him even after his slime substance gets splattered all over the ground and dies. He who is a slime is not allowed to call himself a slime or he will get scolded (it's more like death but whatever) and is forced to fight if there are invaders and apparently he is strong but in front of the Dragon mother, he gets insta killed. His friends are weak mobs like goblins and imps, they also die but are resurrected so it's not exclusive to the slime.
There are several holes in the plot. How did she get rich enough to fly on a private jet.. Did it belong to her friend or not?
Why was she so experienced in fighting dogs and possess knowledge on martial arts (what kind of martial art did she study? Military self defense?)
The humans praying to gods give birth to a sort of power that boosts the gods' powers but they've become so reliant on it that they cannot live without it. Just like drugs except they have certain death from withdrawal
