Picked up a Mysterious Human Skin at the Beginning

There are gold belts for killing people and setting fires, but there are no corpses for repairing bridges and repairing roads. Life shouldn't be like this, and the world shouldn't be like this. I am just a small person surviving in the last days. Why don't those rich and powerful people even give me the last chance to survive? In this case, any evolutionary family, any top organization, any noble inheritance, they all deserve to die! I will prove it by killing! I want to wake up all those who are suffering like me! I want to call on all those who dare to resist! I want to reshape the order of this troubled world! Look how I can make the world surge with just a piece of animal skin!
