It has to do with the fact that his bloodline is purer than the rest of the sect
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?)
his girlfriend left him for another girl T_T so saddening. What "there is only true love between the same gender?" from that day onwards he will be the face of gender equality
his body has a communication barrier, speaking in broken up sentences but gets better as the chapters progress, his/her mom ran away with another dude and his/her dad turned into an alcoholic possibly with debts and hits him/her. No friends which is a good thing because he got no plot armor to give him memories. Somehow he met a rich boy whose mom is a concubine
those words were precisely used during that encounter
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
