The back cover was different from the front; it was as thick as four or five sheets of paper.

There were many small pits of varying depths on it. Could it be braille?

No, braille has a raised texture, but this back cover only had indents, no raised parts.

Interesting, there must be a secret hidden here.

"System, perform a high-precision scan of this page immediately, magnify it a thousand times."

【No problem.】

Huang Ye stared intently at the last page without blinking, feeling as if his eyeballs were about to explode, as if they were no longer under his control.

This time, the system took full control of his eyes, making him think that the panoramic viewing ability might be related to the system.

It wasn't that he saw it himself; the system transmitted the image to him.

The system should be able to control his body, which could also explain how he miraculously dodged Yue'er's attack.

When the system detects that the host is in danger, it can help the host avoid disaster.

The system scanned this page for a full five minutes.

"Old Hu, are you done?"

"Almost done. Oh, I forgot to bring toilet paper. This book feels quite soft; I'll tear out a couple of pages."

"Sir, please stay calm. I have toilet paper here. I brought it just in case you forgot."

"Alright! You're thoughtful. Hand it over when I'm done."

Old Hu quickly took the techniques book that Huang Ye handed back.

"Brat, give me the paper."

The guard outside immediately handed the toilet paper inside.

Old Hu fiddled around for a while and then left the latrine with the guard.

Huang Ye waited for half an hour before staggering out.

He dry-heaved outside for five minutes before leaving the Scripture Repository in a daze, feeling both disgusted and amused.

He returned directly to the lecture hall.

Old Hu had already returned. Seeing Huang Ye enter, he pinched his nose and mumbled:

Enjoying this book? Seek out the original to ensure the author gets credit.

"How was it? No problems, right?"

Huang Ye gave a wry smile, realizing that he couldn't clear his name even if he jumped into the Yellow River.

"I'll transcribe it for you right away. I'm afraid I'll forget."

"Oh, can't you remember it for a lifetime?"

"Well, I find that I forget some things after five days," Huang Ye lied casually.

"Alright, then transcribe it overnight. Fortunately, there aren't many techniques; it should take two or three days."

"Master Hu, I noticed something strange about the back cover page. There are many indents."

Huang Ye deliberately mentioned this to Old Hu to clearly indicate that he wasn't keeping secrets.

Although they had grown closer since their last interaction, he remained cautious of the old man.

The most unpredictable thing in the world is the human heart; one must not be deceived by appearances.

Old Hu usually appeared stingy and greedy, but Huang Ye didn't fully understand his other ways of doing things.

Although their cooperation was successful this time, Huang Ye couldn't guarantee that Old Hu wouldn't kill him for the techniques.

He had read many stories in novels about masters scheming against their disciples.

In reality, there were also many examples of masters and disciples turning against each other, especially in traditional industries where the master-disciple relationship was highly valued.

If Old Hu was genuinely kind to him, it would be fine, but if he wanted to kill the donkey after it had done its work, Huang Ye wouldn't be easy prey.

"Oh! You noticed too."

"Yes, Master Hu, do you know what those indents mean?"

"Hehe, that book of techniques isn't for casual viewing because those indents are too mysterious."

"This book has been in the academy for over three hundred years, and every headmaster has studied those indents."

"No one has figured it out. They suspect it might be a treasure map, but they're afraid it involves secrets of the Immortal Sect."

"So they don't dare let others study it. My borrowing time was short, and I couldn't figure it out either."

"It is indeed very mysterious. Unfortunately, the time was too short, and that page was too complex to remember."

"Even if you held it every day, you wouldn't figure it out. Whether it's a blessing or a curse is uncertain; we mortals shouldn't dream."

"Master Hu, have you prepared the paper and pen?"

Old Hu handed over a set of writing tools, and looking at them, Huang Ye felt a bit dizzy.

When he was a child, his calligraphy practice looked like a dog's scribble.

"Master Hu, I'm used to writing with a quill pen; this thing is too slow."

"A quill pen? What's that?"

"It's a pen made from thicker goose feathers."

"You'll have to find that outside. Use this for now; I'll get you one later."

"Alright, I'll give it a try."

After writing ten characters, Huang Ye was stopped and switched to dictating while Old Hu wrote.

This doubled the speed, and the characters were beautiful, but it still wasn't fast.

"Master Hu, your speed isn't good either. We won't finish in five days. Let's get the quill."

Old Hu looked at Huang Ye suspiciously but still went out.

Taking advantage of this, Huang Ye began to study the techniques.

Huang Ye roughly understood the techniques, which included methods for circulating Spiritual Energy and some spells.

The techniques focused on absorbing, storing, purifying, condensing, and utilizing the Spiritual Energy of heaven and earth.

There weren't many spells, all related to the five elements: metal, wood, water, fire, and earth.

Each element had about three to five spells, which made up the majority of the techniques.

The introduction boasted that these techniques were suitable for anyone with the aptitude for cultivation.

In cultivation novels, cultivators could detect the five elements' spirit roots, absorb the five elements' Spiritual Energy, and use the five elements, which was similar here.

However, aptitude for cultivation here wasn't determined by spirit roots but by "affinities."

For example, if a cultivator was found to be close to fire and adept at using fire elements, they were called a fire-affinity cultivator.

There was no mention of Heavenly Spirit Root or False Spirit Root; everything was expressed in terms of affinities.

Most cultivators would major in one affinity and minor in two, so most cultivators here were tri-affinity cultivators.

Regardless of the affinity, they could cultivate these techniques and use the three-element spells they practiced in the future.

Huang Ye found this somewhat useful, as neither he nor Qing'er and Yue'er knew which affinity they excelled in.

However, Huang Ye felt that he absorbed more than just the five elements' Spiritual Energy. The techniques mentioned other affinities beyond the five elements but didn't specify what they were.

The techniques also included a method for cultivators to perform internal visualization, allowing them to see the color of the Spiritual Energy circulating within their bodies.

Wood was green or cyan, water was blue or black, fire was red or purple, earth was yellow or brown, and metal was gold or white.

The Initial Yang Realm mentioned in the techniques was similar to the Qi Refinement stage seen in novels, where impurities were expelled from the body, continuously improving physical qualities.

The significance of Initial Yang was to nurture a sun-like sphere within the body.

In the Primordial Yang Realm, this sphere would appear inside the body, initially gray in color.

In the Heavenly Yang Realm, the sphere would take on different colors based on the primary element cultivated.

The techniques didn't mention what the realms beyond this looked like; cultivation reached its peak at the Primordial Yang Realm.

If one wished to continue cultivating, they could practice any Heavenly Yang Realm techniques.

Damn, this so-called path to the heavens only reached the Primordial Yang Realm, still far from the heavens.

This was likely a common technique in the cultivation world, with a flashy name.

An hour later, Old Hu returned angrily with three large geese.
