Evil Spirits Descend, and I Crush Them with My Mortal Body

Who says a mortal body can't slay evil spirits? I'll show you exactly how it's done. I've got a System that can deduce anything: techniques, pills, divine weapons, everything in the world. So what if you're a cultivator? Have you ever seen a fist as big as the sky? One punch, and you'll be blown to smithereens. What, your pills can only stop the bleeding? Mine bring you back to full health on the spot! That's how awesome I am.
