The Path to Immortality: Starting with an Analysis of Basic Concepts

"Senior brother!..."

Just as Xiang Sui was enjoying the shocked gazes of the two men, a cloying voice suddenly rang in his ears, startling him so much that his arm trembled for a moment. He turned his head and saw Liang Kuan rubbing his hands with a fawning expression.

"Don't be so disgusting."

Xiang Sui glared at Liang Kuan speechlessly, tossed him a book that was clearly newly copied, then turned to Zhu Yu, whose expression was complicated, and waved his hand with a smile, saying, "Junior Brother, don't worry about it. This 'Chew Gold and Eat Iron' is an incomplete technique."

"The useful information left behind can only cultivate a stomach wall that can filter trace amounts of toxins, and its effectiveness is not even as good as a detoxifying pill, so its actual value is not much."

That's what they say.

But magic is magic, and even if it's incomplete, it still needs to be measured in spirit stones.

You can see Liang Kuan standing to the side, grinning like he's found a treasure.

"I thank my senior brother."

What else could Zhu Yu say? He bowed deeply, keeping this favor in his heart, and vowed to repay it when he was able to in the future.

"Thank you, senior brother. Thank you, senior brother."

When Liang Kuan realized what was happening, he bowed repeatedly to express his gratitude, his large belly protruding. However, he couldn't straighten his back, and his head kept nodding, which was quite amusing.

"Alright, alright."

Xiang Sui waved his hand seemingly indifferently, but in reality, he couldn't suppress the urge to smile. He quickly turned around and said as he walked, "I still have some leftover medicinal herbs from the stomach-nourishing medicine. I'll have the servants deliver them to you later."

"Thank you, senior brother."

Zhu Yu's face lit up with joy. He picked up the spirit stones from the table and caught up with Zhu Yu, saying, "However, I, your junior brother, will still pay for the materials."

"Yes, yes," Liang Kuan chimed in from the side.

"I said I don't need it."

Having already given away the magic, Xiang Sui didn't care about the cost of the materials, which was only a spirit stone or two. Since he was doing a favor, he might as well go all the way. He waved his hand and strode away as the two watched him leave.

Liang Kuan didn't linger. After answering Zhu Yu's questions, he rushed off to his residence.

"No wonder they're not in a hurry at all..."

Watching his figure slowly disappear at the intersection, Zhu Yu shook his head slightly.

I learned this from Liang Kuan.

Unlike those from the spiritual desert who need a year to refine their qi, those from the spiritual ruins have no such time limit, but they must have at least a fourth-grade soul aptitude and pay a considerable amount of spirit stones to enter the sect.

Liang Kuan didn't know the exact amount of spirit stones, only that in order to support his entry into the sect, his grandfather, a spirit plant master, sold two acres of first-tier spirit fields inherited from his ancestors.

"Tsk..."

Everything is subject to comparison. Compared to someone like Liang Kuan, who was more qualified than him but still had to sell his ancestral property to join the clan, Zhu Yu suddenly felt that a one-year term didn't seem so bad.

Return to the stone house.

Zhu Yu couldn't wait to pick up the book on the table. This was the first spell he had ever encountered. Looking at the four big characters "Chewing Gold and Eating Iron" on the book, he took a deep breath, suppressed his excitement, and gently turned the cover.

"In ancient times there was a beast that resembled a bear, with a small head, a single eye, and red scales, which fed on metal..."

The story begins with a description of a powerful demon called the "Iron-Eating Beast," which is illustrated below and looks very similar to a one-eyed bear beast with crimson scales.

The book doesn't mention much else, focusing instead on describing the iron-eating beast's stomach that melts gold and iron.

Time passed slowly.

I don't know how long it has been.

"call..."

Zhu Yu withdrew his gaze, let out a soft sigh, and his brows were filled with the joy of having learned the secrets of cultivating immortality.

According to the book, the technique "Chew Gold and Eat Iron" belongs to the category of flesh and blood mutation, and is classified as a first-grade low-level technique. Once mastered, the stomach can be comparable to an "iron-eating beast," and it has many benefits.

One is the gastric juice that melts gold and iron, which not only refines elixirs more thoroughly but also digests some of the elixir's poison. Furthermore, it can nourish the physical body by consuming some spiritual objects or minerals.

Secondly, it has a secondary stomach that can hold foreign objects. Iron-eating beasts are born with two stomachs, one for digesting food and the other for storing food.

Unfortunately, both the method of constructing a stomach capable of melting metal and iron and the method of constructing a secondary stomach to accommodate foreign objects are incomplete. Only one method, used to lay the foundation and make the stomach wall more resilient, is relatively complete.

"To cultivate a demonic body using a human body, this technique is truly bizarre..."

Zhu Yu sighed inwardly. He didn't have any psychological barriers to this. To mortals, Qi Refining cultivators were no different from demons, and cultivating a demonic body was nothing special.

After gathering his thoughts slightly, he silently recited:

"The technique 'Chewing Gold and Eating Iron' has been included, and useful information has been extracted from it."

[Target: Chewing gold and iron, already included...]

[Grade: Tier 1, Low Grade. Category: Flesh and Blood Mutation]

[The "Metal-Melting and Iron-Refining Stomach Bag" technique is missing "56%" of its data; the information on the spiritual objects used in the technique is missing "63%"; estimated analysis time is "∝".]

[The Nascent Soul Subsidiary Stomach Pulse Dharma Lineage Chart is missing "28%", the information on the spiritual objects used in the spell construction is missing "12%", and the estimated analysis time is "∝"]

[Prescription for strengthening the stomach wall: Complete and optimizable, estimated analysis time "half a quarter of an hour"]

Upon learning that the stomach wall strengthening prescription could be optimized, Zhu Yu's face lit up with joy. He silently instructed his True Sight Eye to analyze it, and then his mind fell on the "Chewing Gold and Eating Iron" technique lineage diagram, his eyes showing contemplation.

The reason he couldn't understand it was because he had too little information about cultivating immortality, and currently there was only one place to obtain information about cultivating immortality, which was the "Lecture Hall".

Previously, due to a lack of spirit stones, entry was not possible.

Now that he has the spirit stone, the "Lecture Hall" is no less than an open and unknown treasure trove for him, and he might be able to deduce and analyze the magic technique "chewing gold and eating iron".

Even if it cannot be parsed, the information obtained is still true and accurate.

"Go, go now!"

Thinking of this, Zhu Yu suddenly became restless. When the servant brought the materials Xiang Sui had given him, he carefully put on his black robe, closed the door, and headed straight for the stone pagoda.

at this time.

Two crescent moons hang from the dome, fireflies flicker along the roadside, and pedestrians come and go frequently.

Zhu Yu dodged cultivators who were clearly skilled in Qi cultivation, and soon a gray-white stone tower came into view.

At the same time, a commotion arose.

"Nine Netherworld Ao cubs, only one spirit stone each."

"Amulets, top-quality amulets. Stick one on your body and you'll never have to worry about the effects of the aura of the amulet again. Three amulets for one spirit stone, selling cheap."

"The calming herb can help one enter a deeper state of meditation..."

"Thirty years of in-depth study of fundamental concepts and methods, guaranteed to teach and teach until you learn..."

"A secret body-refining technique passed down in my family; the more I practice, the stronger I become, making it possible to move mountains and lift peaks!"

"..."

The square was bustling and noisy, with a cacophony of voices; an outsider might mistake it for a marketplace.

Zhu Yu glanced around, especially at the stalls with signs holding up curtains. The stalls were the same, but the cultivators sitting in the back were different.

Without much thought, I stepped towards the stone tower. Within a hundred meters, the information from today's lesson flooded my mind.

Zhu Yu carefully reviewed them and decided to try three of the basic courses first.
