215: Chapter 215 Oversimplifying Things

Three days later, news suddenly arrived from Elder Lu Yuan.

Han Jing personally made a trip to Qingmu Peak. Standing outside Su Cheng's Immortal Cave, he called out in a clear voice, "Junior Brother, Revered Master says the Medicinal Pill will be opened in three days, and he wants you to come and observe."

Su Cheng emerged from his Immortal Cave. Naturally, he understood what Medicinal Pill was being referred to and quickly cupped his hands in thanks.

"Also," Han Jing added, "this time, Revered Master is making an exception to let me and two other Junior Brothers watch as well. It's like getting extra instruction, and it's all thanks to you, Junior Brother."

Su Cheng quickly waved his hands, "Senior Brother Han, you are too kind. It is already my greatest fortune that Elder Lu Yuan is willing to let me stand by and watch. There is no such thing as it being thanks to me."

Han Jing smiled and didn't say anything more.

Three days later, at the summit of Wanhua Peak, in Elder Lu Yuan's Alchemy room.

The Alchemy room was the same one used for refining the huayuan pill last time. The nine-turn profound light furnace still occupied the center, and the Array Inscriptions on the furnace wall moved slowly under the infiltration of Spiritual Qi.

This time, there was no need for assistant hands; Elder Lu Yuan was performing the Alchemy purely by himself, while the four of them, including Su Cheng, observed from the side.

Elder Lu Yuan did not waste any words and started the furnace directly.

The dark golden pill fire fell into the furnace chamber, and the temperature rose to a stable value within three breaths.

Unlike when refining the huayuan pill, this time Elder Lu Yuan took an extra step after starting the furnace.

With a light tap of his right hand on the furnace wall, the arrangement of the Array Inscriptions on the surface of the nine-turn profound light furnace changed instantly. A layer of pale golden light membrane rose from the inside of the furnace wall, wrapping the entire furnace chamber tightly.

Su Cheng's Divine Sense probed toward the inside of the furnace, but it was blocked firmly by that layer of light membrane and could not enter.

Han Jing and the other two Disciples had obviously encountered the same situation. Perhaps because the three of them knew about this in advance, there was no particular fluctuation on their faces.

Last time, when refining the huayuan pill, they were assistant hands and needed to inject Spiritual Qi into the furnace through the formation base, so the Pill Furnace naturally did not block their Divine Sense.

But this time was purely for observation; Elder Lu Yuan had no reason to lay everything inside the furnace open for them to see.

Moreover, the status of the spirit nurturing pill within the Sect was quite high; even Immortal Master Lu Yuan could not pass it on at will.

With his Divine Sense unable to enter, the information he could obtain was greatly reduced.

Su Cheng could only capture clues from the outside.

The temperature of the pill fire for the spirit nurturing pill was twenty percent lower than that of the huayuan pill; this could be judged from the heat radiating from the outside of the furnace wall.

The main Spirit Medicine for this kind of Medicinal Pill acted on the Divine Soul; if the temperature was too high, it would destroy the medicinal properties, leading to a significant reduction in efficacy after the pill was formed.

The first main Spirit Medicine entered the furnace: five-hundred-year-old Dragon Saliva Grass.

Su Cheng stared at every movement of Immortal Master Lu Yuan.

The moment the Dragon Saliva Grass was sent into the furnace opening, a wisp of spiritual fluctuation leaked from the gap in the furnace lid, only to be blocked by the light membrane immediately.

Su Cheng only captured the initial moment; the spiritual fluctuation on the grass leaves climbed sharply, and then he couldn't perceive anything at all.

Immortal Master Lu Yuan's hand seals changed three times. From the outside, one could see the trajectory of the Spiritual Qi flowing from his fingertips, but where the medicinal power inside the furnace was guided, and to what extent it was suppressed, were all completely isolated from his perception by the light membrane.

The second main Spirit Medicine: hundred-year-old Soul Xing Leaf.

Su Cheng could only infer the timing of this Spirit Medicine entering the furnace from the rhythm of Elder Lu Yuan's hand seal switches.

After the two main Spirit Medicines converged in the furnace, a subtle change appeared in the temperature distribution on the outside of the furnace wall.

The left side was slightly lower, and the right side was slightly higher, indicating that the medicinal power inside the furnace was undergoing asymmetric Fusion, but he could not see how it was specifically controlled.

Then came the auxiliary medicines.

Elder Lu Yuan swept his right hand across the stone table, and six or seven auxiliary medicines were swept up by Spiritual Qi at the same time.

But he did not display them one by one like last time. Instead, the moment the auxiliary medicines left the table, he used an extremely fast hand seal to shatter the outer shells of all the auxiliary medicines, revealing the medicinal core inside.

The medicinal cores had not stayed in the air for more than half a breath before they were swept into the furnace chamber by the pill fire.

From the grabbing to entering the furnace, it took no more than two breaths in total.

Su Cheng's Divine Sense operated at full power, desperately trying to capture the spiritual fluctuation characteristics of each auxiliary medicine as they were briefly exposed in the air.

Two breaths—it was too short.

Although his Divine Sense had reached the Late Foundation Establishment Stage, it was still beyond his capability to distinguish the spiritual fluctuation frequency bands of six or seven Spirit Medicines and calculate their respective proportions within two breaths.

He caught three of them.

The three-hundred-year-old Soul-Fixing Grass had extremely obvious characteristics, carrying a steady and heavy Earth-element Spiritual Qi pulse; it was one of the known auxiliary medicines for the spirit nurturing pill.

The hundred-year-old Green Heart Lotus had Water-element Spiritual Qi, cool and soft, used to neutralize the dryness of the Dragon Saliva Grass.

For the third one, Su Cheng frowned.

The spiritual fluctuation of that Spirit Medicine was extremely weak, with a frequency band in the fuzzy zone between the Wood element and the Water element.

Not enough, far from enough; he could not determine what this auxiliary medicine was.

The remaining three or four flashed by so quickly that he didn't even have time to lock onto their fluctuation characteristics.

After the auxiliary medicines entered the furnace, all changes were sealed inside the furnace by the light membrane.

All Su Cheng could perceive were the weak fluctuations in the furnace wall temperature and a wisp of medicinal fragrance occasionally escaping from the gap in the furnace lid; even the medicinal fragrance was a residue filtered by the light membrane, and he could not discern the specific ingredients.

Su Cheng sighed in his heart; sure enough, he had thought things too simple.

The complete proportions and input sequence of the auxiliary medicines were the core secrets of the spirit nurturing pill's Pill Formula. All he could do was intercept as many information fragments as possible during the observation.

With the characteristics of the three auxiliary medicines added to the two known main Spirit Medicines, the puzzle pieces in his hand had increased to five.

But it was still far from a complete spirit nurturing pill Pill Formula.

The Alchemy lasted for a full two days and one night.

Elder Lu Yuan did not rest throughout the entire process, and the temperature conducted from the outside of the furnace wall remained stable throughout, exactly the same as when refining the huayuan pill.

When the furnace was finally opened, the light membrane dissipated as the furnace lid was lifted. Three spirit nurturing pills lay quietly at the bottom of the furnace, with fine silver patterns flowing on the surface of the pill body, and the medicinal fragrance was restrained and did not dissipate.

High Grade; all three were High Grade.

A look of satisfaction appeared on Elder Lu Yuan's face.

"Su Cheng, take all three." Elder Lu Yuan handed over the jade bottle, his tone as casual as if he were handing out snacks.

Su Cheng was slightly stunned and subconsciously glanced at Han Jing and the other two beside him.

Han Jing waved his hand, "Take it. If we need it, Revered Master will not be stingy."

Elder Lu Yuan put his hands behind his back, "This furnace of pills was originally refined for you. As for the Sect…"

He glanced at his three Disciples.

"Do not spread the word about the spirit nurturing pill refined today, so as to avoid causing controversy in the Sect."

Han Jing and the other two replied in unison.

It was a common occurrence for Elder Lu Yuan to go into seclusion for Alchemy. The entire Sect only knew that the Alchemy room on Wanhua Peak had started a furnace again. As for what was being refined in the furnace, no one would be stupid enough to go and ask about the Alchemy content of a Golden Core True Person.

Su Cheng put away the jade bottle and cupped his hands in thanks.

The Medicinal Pill was warm to the touch, and the silver patterns flowed on his palm for a moment before falling silent.

But Su Cheng's mind was no longer on this Medicinal Pill.

The purpose of the observation had not been fully achieved.

He had only touched the tip of the iceberg regarding the auxiliary medicine proportions of the spirit nurturing pill. Trying to reverse-engineer the complete Pill Formula from these few fragments was no different from a blind man touching an elephant.

It seemed there were no shortcuts to take. He would just have to win a top-three spot in the Alchemy Hall Competition and enter the Alchemy Hall treasury in a proper and upright manner.

Su Cheng put the spirit nurturing pill into a jade box and sealed it together with the few he had accumulated before.

After returning to his Immortal Cave, not long after he sat down, the voice of a Utility Disciple came from outside the Immortal Cave.
