One Sword and All Living Beings

The world is so big, who wants to live his whole life for pigs and dogs? I, Li Buqun, have slept in pig pens and eaten pig food, but I don't believe in fate. I only believe in whether the sword in my hand is sharp enough and my fist is strong enough. If there is a path to immortality that blocks my way, I will only split it with one sword!
