The Light of the Sword and the Shadow of the Sword

I want to become the pinnacle of power on the continent. The law of the jungle is the only rule in this world. If you have strength, you can do anything; if you don't have strength, you can't have anything. I really want to have comments and rewards, otherwise there will be no motivation. . . .
