Traveling to another world and being looked down upon by the natives?
Then kill!
Being bullied?
Then kill!
You can become stronger by killing enemies with the system in hand. In this different world where the jungle is strong and the strong eat the weak, if you don't become strong, you will have no choice but to be bullied by others.
Now that you have the capital, just kill, kill, kill!
Kill everyone in the world for injustice, kill everyone in the world who looks down on you!
