Starting with a Dual Cultivation Cauldron, Feeding Senior Sister in Return

A handyman in the Hehuan Sect, golden finger, mischievous, top-tier, playing dumb, lying low in the sect, scheming. Ji Wubing starts as a useless waste in the Hehuan Sect, washing basins, wearing a tattered robe that only covers half his crotch. In his dire straits, with his pants flapping in the wind, being squeezed by female demons, starving and cold, forced to swallow leftover dregs that even dogs wouldn't eat, he fishes out a treasure from the icy pool in the harsh winter—a [Peach Blossom Pink Jade Vase] that can expand to the size of a roof or shrink to tiny, containing exquisite yang dew. After watering with the yang water from the vase, the yang herbs in the desolate valley grow a hundredfold, thick as pestles! "Little brother, can your pills make me virile for ten days? Give me ten! What? Not selling? How about I give you two Hehuan flying blades for protection?" Facing the pursuit of a pure fairy and the frenzy of demonic sect leaders, Ji Wubing clutches the golden vase in his underwear, blushing, and says, "Masters, slow down, I'm just a weak handyman!" — Description from novelcodex.org
