Yes! MC has lived on earth but at present he is not human but a fragment of universal core, materialized itself(more will be revealed in later chapters), means he is already a god level entity(which mc doesn't know himself, so he subconsciously feels huge pride and attitude as the strongest being).

Yes! MC has lived on earth but at present he is not human but a fragment of universal core, materialized itself(more will be revealed in later chapters), means he is already a god level entity( which mc doesn't know himself, so he subconsciously feels huge pride and attitude as the strongest being). Also, as the MC is made up of the universal core's fragment, it numbs its feeling when he kills some one but being a resident of earth, it also prevents him from turning into a cold blooded murderer.

As the mc is new in this world, he doesn't know all the powerhouses of this world and also our mc is smart and cunning, not some overconfident young master type character, to blindly challenge any opponents or species without knowing their full capabilities as MC has a mindset of "every predator has its own predator", so it's doesn't hurt to be careful.

The system you mentioned is not like the system of other stories, where the system controls the MC's action . But in this story, it is rather like an independent conscience and acts as assistant, who assists mc and has no control over MC's action. And mc at present familiarising his new found power with the help of his assistant.
