Black Dog

In the theory of evolution in a parallel world, who is the master between orcs and humans? In this world that is like an endless hell, who will stick to the bottom line in their hearts? I woke up under the clouds and opened my eyes to face the world: Empires, clans, weird martial arts, descendants of strong men, machine skills; giant diamonds, dragon-armed bears, divine tigers, flying chickens, thousand-year-old turtles... Wars have never stopped, and heroes appear frequently. It turns out that this is an era of "dogs in black".
