Chapter 53: Sedimentation
In the early stage of qi refinement, only six spiritual herbs are needed for the Spirit Gathering Elixir, while in the mid stage, seven spiritual herbs are required for the Clear Spirit Elixir. For the ordinary Purple Spiritual Elixir in the late stage of qi refinement, nine spiritual herbs are necessary.
The Azure Spirit Pill requires even more herbs than the Purple Spiritual Elixir, reaching eleven spiritual herbs, and the required age of these herbs is also higher, consuming more spiritual energy.
After scattering a hundred spiritual stones and spending seven or eight hours to accelerate their growth, Liu Yu obtained thirty-five portions of spiritual herbs for refining the Azure Spirit Pill. Along with the original five portions, he now had a total of forty portions.
This ratio is much lower than that of the Spirit Gathering Elixir and the Clear Spirit Elixir, indicating that the consumption of spiritual stones will continue to increase. As the age of spiritual herbs grows, the consumption of spiritual stones will also rise, Liu Yu concluded.
He placed the harvested seeds in a wooden box and arranged them in the cabinet of the small wooden house on the left side.
After Liu Yu organized the three wooden houses, they were no longer in the disarray they had once been. Each medicine cabinet in the small house was neatly arranged, with wooden boxes containing seeds placed in an orderly manner, and each box was engraved with the name of the seeds, making it easy to find.
Once he had organized the seeds, Liu Yu delivered batches of spiritual herbs to the outside world, using the prepared jade boxes to preserve their medicinal properties.
With his Primordial Spirit leaving the Immortal Abode, Liu Yu took out the small booklet detailing his experiences in alchemical pill refining. As he refined pills more frequently, this booklet recorded many insights, guesses, and issues encountered during the process, filling up nearly half of its pages with dense handwriting.
Looking at the thick alchemical pill refining notes, a sense of accomplishment surged in Liu Yu's heart. This was proof of his steady progress in learning pill refining, a testament to his growth on the path of alchemy.
He flipped through the booklet, revisiting his insights, and stopped at a certain page in the middle. This page recorded a fire control formation that Liu Yu had copied from the Scripture Vault, which was far superior to the basic fire control formation recorded in "Fundamentals of Alchemy." The flames it ignited were at a higher temperature, enabling faster melting of higher-aged spiritual herbs while minimizing the loss of their medicinal properties.
The fire control formation in "Fundamentals of Alchemy" was merely the most basic one, with significantly lower flame temperatures compared to this one. As Liu Yu's alchemical skill improved, he found the basic formation increasingly inadequate.
The fire control formation recorded from the Scripture Vault was called the Crimson Flame Formation, and it was much more complex to set up.
Liu Yu cleared out all the items from the adjacent room on the left, which would now be used as his alchemy room.
Holding the small booklet in one hand, he meticulously engraved the Crimson Flame Formation onto the ground according to the notes, completing it in about fifteen minutes.
The Crimson Flame Formation had a much higher flame temperature, naturally consuming more spiritual energy, requiring as many as five spiritual stones to activate the formation.
He placed the five spiritual stones at the five nodes in the corners of the Crimson Flame Formation, took out the Purple Mysterious Cauldron, opened the fire door at the bottom, and positioned it in the center of the formation. One portion of spiritual herbs for refining the Azure Spirit Pill was placed beside him, and the preparations for alchemy were complete.
With both hands, Liu Yu waved the spell technique continuously, casting several spell techniques on the formation. The formation immediately lit up with a red glow, and the embedded spiritual stones began to shine, with spiritual energy starting to circulate and consume.
