Both star a MANLY badass protagonist traveling the desert with a child or two. You have warlords vying for power in a chaotic world, and lots of brutal violence. They mostly work alone but pick up some strong allies along the way. The characters in Biao Ren are a bit more nuanced than the good guys and pure scum in HnK.
