: Deduction, Prescription

Having obtained what he wanted, Zhu Yu didn't linger. He looked around, stepped out, and headed straight for the next room where the professor taught "Spell Construction and Spiritual Object Explanation."

A quarter of an hour passed.

Zhu Yu walked out of the room with excitement in his eyes, and without the slightest hesitation, strode towards the room where the professor was teaching "Detailed Explanation of the Categories of Techniques".

soon.

He was like an oil rat that had fallen into an oil vat, and then he entered the room where the professor taught "Detailed Explanation of the Five Elements Spiritual Objects", "Detailed Explanation of Flesh and Blood Transformation", and "Guidelines for the Practice of Magic".

One hour later.

Zhu Yu stepped away from the stone tower, and the clamor and noise rushed into his ears, waking him from his daze. He turned around and glanced back at the mottled stone tower, tightened his black robe, and joined the square market.

The twinkling lights of the flowers and grass illuminated the path, which continued without interruption. Soon we returned to our lodgings.

"call..."

Sitting in the chair, after drinking several cups of tea offered by Liang Kuan, Zhu Yu let out a long sigh, thought for a moment, and silently recited:

"I will establish a model, using my own diagram of the laws of heaven and earth, to deduce and analyze the technique 'Chewing Gold and Eating Iron'."

[Tier 1 Low-Grade Spell "Chewing Gold and Eating Iron"]

[The diagram of the Meridian Path for Melting Gold and Iron in the Stomach Bag, the spiritual objects required for constructing the technique, is currently in the process of analysis (1%), with an estimated time of three months.]

[Diagram of the Subsidiary Stomach Pouch for the Art of Storage; spiritual objects required for the construction of the technique; analysis in progress at "1%"; estimated time "seventeen days"]

"With more information about cultivation, I can now fully deduce the techniques."

Zhu Yu's face lit up with joy, and he was somewhat excited.

This is not just about deducing a complete first-tier low-grade spell; it also represents infinite possibilities for the future.

As long as enough information is obtained.

Becoming an immortal? Achieving eternal life? It doesn't seem impossible.

However, while he could dream about it, he had to focus on the present. Zhu Yu forced himself to suppress his excitement, got up, took the package Xiang Sui had brought to the table, and opened it.

What comes into view are the roots and stems of plants, some withered and some emerald green, a warm stone with white and yellow stripes, and a set of tools for boiling medicinal herbs.

"Huang Menghua, Fuling, Huqiancao..."

Taking out the tools and setting them aside, Zhu Yu glanced at the ordinary medicinal herbs in the package before his gaze fell on the white and yellow stone.

It is a "medicinal stone", which is made primarily of the low-grade spiritual medicine "white jade mushroom", supplemented with sulfur and various other medicinal materials, and refined with alchemical fire.

It is also a key ingredient in prescriptions for strengthening the stomach wall.

To avoid discrepancies with the prescription deduced by the "Eye of True Sight," Zhu Yu picked up the medicinal stone, scraped off some powder with his fingernail, and put it in his mouth.

Suddenly, a burning sensation surged up, followed by a pungent, spicy smell. After the analysis was completed, I quickly opened my mouth to spit it out and then took a sip of water to rinse my mouth.

[The ingredients contained in this medicinal stone include: white jade mushroom (36%), sulfur (28%), stone tail grass (12%), fritillaria (8%)... which differs significantly from the main ingredients in the prescription.]

【以药石为主材，烧为药汤服用后预估效果有原方「45%」。增加黄梦花「36%」茯苓「25%」胡钱草「65%」...预估效果可达至药方「91%」】

"Ninety-one percent, that's good."

After understanding the information, Zhu Yu nodded slightly. It was just a prescription for a preliminary technique, so there was no need to strive for perfection. He then proceeded to prepare the medicine according to the "Eye of True Sight" and began to process the medicinal materials one by one.

I don't know how long it has been.

Wisps of smoke rose from the stone house. Zhu Yu squatted in front of the medicine stove, occasionally fanning himself with a leaf whose fluorescent light was gradually dimming.

The pungent aroma wafted through the air, drawing the attention of passersby with a range of reactions: surprise, curiosity, doubt, and disdain... and so on.

Despite the various gazes from the crowd, Zhu Yu remained unmoved. After the medicine furnace was opened three times, he carried it back to his room. As he poured it out, a dark brown liquid flowed into the bowl.

Zhu Yu examined the color and then took a sniff.

The medicinal liquid did not have the pungent and unpleasant smell it had when it was first boiled; instead, it had a fresh, herbal aroma reminiscent of boiled mushrooms, which was a sign that the liquid had been successfully prepared.

"good."

Zhu Yu nodded in satisfaction, tilted his head back, and drank it all in one gulp.

The medicine tastes slightly bitter at first, and you don't feel much when you swallow it. But as time goes on, you gradually feel a burning sensation like you've swallowed a lot of chili peppers, and this sensation gets stronger and stronger.

Until the very end.

It felt as if he was swallowing not medicine, but a scalding hot coal.

Waves of burning pain surged through him. Just when Zhu Yu felt like his stomach was about to be burned through, a cool sensation suddenly appeared, easing the pain. But just as he breathed a sigh of relief, the burning pain returned.

If there were any cultivators here, they would be able to discover it.

As Zhu Yuna's stomach acid churned under the amplified medicinal liquid, it continuously eroded and corroded the stomach wall. Whenever large areas of the stomach wall appeared mottled and ulcerated, wisps of emerald green energy emerged, quickly repairing the damage to the stomach wall and making it more resilient.

And so it goes, over and over again.

One hour later.

"call..."

As the burning pain in his stomach subsided like a receding tide, Zhu Yu couldn't help but breathe a sigh of relief. After catching his breath for a moment, he sat up and silently recited:

"Establish a model to detect the effects of the medicine before and after administration, and predict the effects after repeated administration..."

The absorption rate of the medicine was 97%, but the effect decreased by 53% with each subsequent dose.

[The stomach wall is five times stronger, and digestion and absorption are three times better...]

"As expected of a prescription that precedes the magic."

Zhu Yu's face lit up with joy. He touched his chest, got up, picked up the medicine stove and the weighed medicine packet, and walked out of the room.

Wisps of smoke rose from the chimneys, adding a touch of warmth and life to the quiet street.

Just after Zhu Yu returned to the room with the heated medicine stove.

The door of the adjacent stone house slowly opened, and a girl with delicate features and heavy dark circles under her eyes peeked out. She glanced at the extinguished fire, her eyes filled with doubt.

"Is this reclusive guy sick? Why is he brewing his own medicine?"

Tong Xuan didn't think much of it, assuming Zhu Yu was just bored. She yawned, rubbed her eyes, muttered that she would just have to hold on for a few more days, and then shrank back inside.

Time passed slowly.

Zhu Yu took two doses of the medicine in succession, and only stopped when it had no effect at all.

And that's the effect.

The stomach wall is nine times stronger than before, and digestion and absorption are six times stronger.

"Tomorrow I'll buy a few bottles of meditation liquid with my senior brother and see how effective it is."

Having made up his mind, Zhu Yu quickly washed up, took out the bottle containing the "Soul-Scattering Pill," poured out one pill and swallowed it, then sat cross-legged and fell into meditation.

The next day.

Six full moons appeared on the dome.

A group of seven people, led by Xiang Sui, knocked on the door of the stone house as agreed.

The wooden door creaked open.

As soon as Zhu Yu stepped out, he saw five men in black robes bow to him in unison, saying, "We thank Master Zhu."

The group looked up.

The visitors were none other than his first apprentices Xun Su, Ni Ying, Qiao Hewei, Bai Meng, and Fu Hongxi.

Behind them, Liang Kuan winked and opened his mouth to say something silently.

Although there was no sound, Zhu Yu still understood what he meant: "The tuition fee has been doubled." His face immediately lit up with a warm smile, and he gestured to the five celestial seedlings.

"Fellow disciples, please don't stand on ceremony, come in quickly."
