Gruel Mud Immortal Gu remnant recipe

Gu Immortals bringing damaged remnant recipes worth less than ten feet of treasure light soon return with copies reaching thirty to forty feet. None of the gruel mud recipes on offer satisfy Fang Yuan, so he keeps selling mud and keeps refusing every trade. ^{ch. 475}

Immortal Mudfeet offers a remnant recipe with sixty five feet of treasure light, lower than rival bids, and closes the gap with ten thousand hairy men. Fang Yuan rejects an all young batch as too weak for refinement work, and after haggling Immortal Mudfeet sells over three thousand old hairy men and over seven thousand young ones for the recipe plus half an immortal essence stone. The recipe holds only sixty percent of its contents, tampered with many times over, so Fang Yuan still has to sort the true lines from the false ones, but he treats the damaged copy as a foundation for deducing the complete recipe later. ^{ch. 491}

Another batch of gruel mud sold in treasure yellow heaven earns Fang Yuan a further remnant recipe of Gruel Mud Immortal Gu. The remnant recipes he sold earlier get resold again by Little Hu Immortal after a gap of time, this round for eleven immortal essence stones, though repeated sales drop a recipe’s treasure light and make the method a poor long term income. ^{ch. 508}

Fang Yuan activates the rank six Immortal Gu Delight in Water and Mountain to feed the light of wisdom, and in a dozen breaths advances the deduction of the gruel mud recipe by one percent, progress that would otherwise cost him half a year alone. The base he works from is a sixty percent remnant recipe collated from the copies he traded for, and completing a rank six Immortal Gu recipe from nothing would cost over a hundred beads of green grape immortal essence. Fang Yuan calls the gruel mud remnant recipe their most promising lead, but finishing it will still take about forty beads of immortal essence, more than he and Tai Bai Yun Sheng can safely spend while northern plains Gu Immortals hunt for them. ^{ch. 655}
