[No female lead + no saintly protagonist + beast-taming]
I transmigrated to another world and got an attribute System from the start!
So what if my bonded spirit beast, a slime, has an F-rank aptitude?
Add fusion attributes, and I can transform into a beast-taming alchemist!
Add rubber attributes, and by sharing abilities, I become a rubber man in another world!
Add elemental attributes, and my spirit beasts become immune to every element!
Add illusion attributes, and my slime can transform into any other demon beast!
“Help! I want to report this guy! His spirit beast is cheating!”
“Weren't we supposed to fight one-on-one? What do you call that whole army of slimes behind you?”
P.S. I can't do this synopsis justice, so please read the story itself.
