I'm travelling in Fantasy World as Symbiote!

I've reincarnate as monster in fantasy world. But its not fun as I expect, this world is so dangerous. Just looking at these mutation creatures almost make me vomit.

Fortunately, as main character I have system. After I build resistant toward those horor monster, killing them and evolved was my only joy. But this did not last long.

......

Boring... Boring... Boring... Is there no human here?... Eh? Why I'm still here? The world is so big what am i doing staying here? Lets go! Lets go!

......

Whoa, the world power up system was so messy, its like the author mixed all possible cultivation method. Cultivator? Mage? Superpower? Knight? Card? Monster integrate? Bloodline warrior? Potion that can evolved you to higher order? There more? Alright, I've decided to round the world.
