Unsung Hero Guardian

With a single male protagonist and no female protagonist, the protagonist is not invincible. Half grown, not invincible. The protagonist does not have any superpowers, spells, supernatural powers or divine powers. All the protagonist possesses is the body of the God of War. It will connect many worlds, such as prehistoric times, all worlds and ultra time and space. Thank you for your support! I will keep updating it. It won't suck.
