Chapter 697
In the cultivation stone chamber, the alchemy furnace was set up, and the furnace fire burned very steadily.
Li Yuan sorted the medicinal herbs and placed them on the stone platform. The four pill formulas—the Origin-Returning Infant-Nourishing Pill, Infant-Nurturing Origin-Condensing Pill, Yuan Condensing Powder, and Spirit Essence Bone-Tempering Pill—each occupied a section, enough for continuous refinement for several days.
First furnace: the Origin-Returning Infant-Nourishing Pill.
The herbs entered the furnace, and the furnace fire was suppressed to thirty percent. Li Yuan reached out with spiritual power, guiding and fusing the medicinal properties within the furnace. After reaching major accomplishment in the fourth-order alchemy art, many techniques had long since been carved into his instincts, allowing him to hit the precise marks without much thought. Myriad image retrospection circulated along with it, and any slight deviation in the medicinal properties within the furnace was pulled back in time.
The medicinal liquid condensed, and the pills formed.
The furnace lid lifted, and three Origin-Returning Infant-Nourishing Pills rolled into the jade bottle. The pill surfaces were rounded, and the medicinal fragrance was very rich. All three were fine products.
Second furnace: the Infant-Nurturing Origin-Condensing Pill. The herb proportions were adjusted slightly, the furnace fire was suppressed to twenty-five percent, and the pill-condensing technique changed from pushing to guiding. Four pills formed: three fine products and one superior product.
Third furnace: Yuan Condensing Powder. Powders did not condense into pill shapes, and the final step required scattering the medicinal properties into powder, making the control of heat even more demanding.
The pills formed—fine products.
Fourth furnace: the Spirit Essence Bone-Tempering Pill.
The four medicinal pills came in rotation, one furnace after another, with almost no stopping in the middle. The major accomplishment techniques grew steadier and steadier through repeated refinement, and that
