CHAPTER 120: The Might of the Li Xuan Sword
Liu Yu planted eleven types of spiritual herb seeds, comprising both main and auxiliary herbs, with each type consisting of ninety portions of alchemical materials. He divided them into different areas and planted them at intervals.
Among the eleven spiritual herbs, the one with the longest growth cycle was the main herb, Azure Spirit Grass, which took one hundred and fifty years to mature to its growth limit and produce seeds. According to the speed of maturation in the Immortal Abode, it required seven and a half hours.
Liu Yu patiently waited beside the black spiritual farmland, immediately replenishing any patch of spiritual soil that showed signs of yellowing and insufficient spiritual energy.
The spiritual herbs that ripened first were quickly harvested, and their seeds were collected to prevent them from continuing to grow and wasting spiritual energy.
After seven and a half hours, all the spiritual herbs needed for refining the Azure Spirit Pill were mature. Liu Yu carefully placed all the herbs into jade boxes and left the Immortal Abode.
"It’s time to upgrade to a higher-grade alchemy furnace," he thought.
The Purple Mysterious Cauldron was only a medium-grade magical artifact. As he began refining higher-grade elixirs, its assistance became less significant. If he were to refine foundation establishment stage elixirs, it would even become a burden.
With this thought flashing through his mind, Liu Yu went to the alchemy room previously established, took out the Purple Mysterious Cauldron, and placed it on the ground.
This time, he didn’t set up the "Crimson Flame Formation" to ignite the flames. The foundation establishment true fire was already sufficient to meet the alchemical requirements, producing high temperatures without consuming too much magical power, although the stability of the flames was somewhat lacking.
However, after reaching the foundation establishment stage, his spiritual consciousness had significantly improved, and he believed he could control it within an acceptable range.
Liu Yu flipped his palm, and a pale red flame flower appeared in his palm; this was the foundation establishment true fire!
With a gentle wave of his arm, the foundation establishment true fire fell onto the fire gate beneath the Purple Mysterious Cauldron, quickly growing to the size of a baby's head and beginning to heat the cauldron.
After the preheating was complete, Liu Yu enacted a spell technique, and the cauldron lid opened slightly.
He then added the spiritual herbs into the cauldron in the order and proportion indicated by the formula.
Removing impurities, extracting the essence of the herbs, merging, condensing the pill, and opening the furnace—each step was something Liu Yu had become incredibly adept at. After reaching mid foundation establishment stage, the success rate for refining the Azure Spirit Pill had officially risen to forty percent.
With his current magical power, refining five batches would consume over half of it, forcing him to pause and sit in meditation to recover. Fortunately, Color Lotus Mountain had a second-tier mid-grade spiritual vein, allowing for a relatively quick recovery of magical power. He could refine nine batches of Azure Spirit Pills a day.
Due to the higher temperature of the foundation establishment true fire, the speeds of removing impurities and refining the essence were greatly enhanced.
After ten days, all ninety portions of spiritual herbs had been refined into pills, yielding two hundred and ninety Azure Spirit Pills.
Once he completed refining the Azure Spirit Pills, he didn’t exit the session immediately. Instead, he took out the newly acquired Wind Escape Boat and Li Xuan Sword to begin their ritualistic refinement.
Since Geng Yuanzhang had voluntarily transferred them, the spiritual consciousness imprints within the two spiritual artifacts had been erased, eliminating the need for him to spend time on that.
Liu Yu sat cross-legged on a meditation cushion, with the superior spiritual artifact Li Xuan Sword hovering in front of him. With a wave of his hand, the foundation establishment true fire appeared beneath the sword, beginning to expel the magical energy residue left by other cultivators.
