After My Talent Hit Zero, I Became the Cultivation World’s Favorite Buffoon

Fantasy novel + comedy Li Goudan's life motto: "So what if I have zero talent? At least I don't get struck by lightning when I go outside!" He inherited a "sack that can hold anything," a battered old sack marked "Fertilizer." Other people use it to carry grain, but he uses it to collect "the side effects of other people's talents": the fire that fire-spirit-root cultivators breathe out, the electricity that lightning-spirit-root cultivators shed, and the grass sliced by sword cultivators' sword energy... Once inside, it ferments into "plain and simple power" (effect: a punch hits like a farmer swinging a hoe. It isn't very powerful, but it's wonderfully down-to-earth).
