I'm in Yellow Maple Valley, and I have one equipment slot!

Zhou Yuan pondered for a moment, not giving a definitive answer: "Uncle-Master Lin, this pill formula is quite exquisite. I need some time to comprehend it before I will attempt to refine it. I cannot guarantee that I will succeed."

"It's alright."

Lin Xu seemed to have anticipated this. "Keep this jade slip safe. You can use this token to get three portions of the medicinal herbs needed from Senior Brother Ma at the Hundred Herbs Garden. I've already made arrangements..."

As he spoke, he took out a blue jade talisman engraved with the character "Lin" and handed it to Zhou Yuan.

"Thank you, Uncle Lin!" Zhou Yuan accepted the jade pendant, a thought flashing through his mind—this was an opportunity.

After a slight hesitation, he cupped his hands and said, "Uncle-Master Lin, this disciple has another request."

"speak."

"I have recently had some doubts about alchemy and would like to consult the sect's richer classic texts for verification. I wonder if my senior uncle could vouch for me and allow me to enter the Yuelu Hall for a look?"

Zhou Yuan's tone was earnest.

Yuelu Hall is a vital place in Huangfeng Valley that houses a vast collection of cultivation manuals, including formulas for alchemy, diagrams for refining weapons, and essential techniques for array formations. Normally, only cultivators at the Foundation Establishment stage or above are allowed to enter.

If a Qi Refining disciple wishes to enter, they must be guaranteed by a Foundation Establishment cultivator, or pay a considerable sum of spirit stones.

Lin Xu frowned and glanced at Zhou Yuan, but quickly relaxed.

"Can."

He nodded. "I will give you a talisman; you may use it to enter the Yuelu Hall..."

"Disciple understands! Thank you for your kindness, Uncle-Master!" Zhou Yuanqiang suppressed his excitement and accepted the silver talisman handed to him by Lin Xu.

Lin Xu gave a few more instructions on the precautions for refining the "Jade Condensation Pill" before summoning a flying magic artifact and flying away from Xuankun Mountain.

Watching Lin Xu disappear into the horizon, Zhou Yuan immediately returned to his cave, his heart surging with emotion.

Yuelu Hall!

That's the foundation that Yellow Maple Valley has accumulated over hundreds of years!

Although access to the core inheritance is definitely impossible, the value of those open and universal alchemy formulas, weapon refining diagrams, basic formations, spiritual herb identification and other classic texts is immeasurable!

He quickly organized his storage bag and took all the remaining nearly two thousand spirit stones with him.

Copying pill formulas inside Yuelu Hall requires paying with spirit stones.

A moment later, he left Xuankun Mountain and flew straight towards the depths of Huangfeng Valley, towards the Yuelu Hall.

Yuelu Palace is located in the heart of a mountain in the core area of ​​Huangfeng Valley. The entire mountain is shrouded in a powerful array, and from a distance, it is shrouded in clouds and mist, exuding an ethereal and otherworldly aura.

Upon closer inspection, one can feel the richness of the spiritual energy here, far surpassing that of Xuankun Mountain.

The entrance to the palace was not outside the mountain, but on a platform halfway up the mountain, hidden by vines. Zhou Yuan used the talisman given to him by Lin Xu to break through the outer barrier and enter.

"Did you break the seal?!"

Two people were guarding the entrance. One of them looked Zhou Yuan up and down and asked him a question.

Zhou Yuan remained calm and took out the silver talisman given to him by Lin Yue, infusing it with a trace of magic power.

"Disciple Zhou Yuan, with the guarantee of Martial Uncle Lin, has come to Yuelu Hall to consult the classics."

Zhou Yuan cupped his hands in greeting.

After the two law enforcement disciples examined the talisman and carefully looked at Zhou Yuan, confirming that the talisman was genuine and not forged, their attitude softened slightly.

"It turns out he was the one who vouched for him."

However, Yuelu Hall has its own rules, and since this is your first time here, you should know…”

The other person began to routinely recount the rules of the palace, which were largely the same as those Lin Xu had mentioned before, but were more detailed and strict.

Zhou Yuan nodded repeatedly, indicating that he had remembered it.

"Go in..."

One of them led Zhou Yuan into the main hall, which contained a large hall.

The Yuelu store is not located here.

Instead, they were transported there via a teleportation array.

Since it was Zhou Yuan's first time here, he was given free teleportation this time.

A flash of white light followed, and everything became clear.

Zhou Yuan appeared in a large hall.

It is about thirty feet in diameter on the left and right, and four or five feet high, with pale red crystals inlaid on the surrounding green rock walls.

A thin layer of white sand on the floor made the entire hall look clean and tidy.

Zhou Yuan glanced at it, and then walked into the passageway with the character "Dan" engraved on it.

This passage isn't very long.

After walking a dozen steps and turning a corner, a slightly larger house appeared at the end of the passage. Inside the house was a long table, and an elderly man with a ruddy complexion was standing beside the table, smiling at Zhou Yuan.

Behind the table were several dilapidated shelves against the wall, filled with various cauldrons, raw materials, and jade slips.

"Greetings, Senior Master!"

Zhou Yuan quickly bowed.

"Alright, just call me Old Xu!"

The old man casually asked, "What are you looking for here?"

"This junior would like to consult some prescriptions for alchemy!"

Zhou Yuan spoke truthfully.

Go!

The old man took out a black token.

After mana was injected into it, a stone staircase leading to the roof appeared in the open space between it and the shelf behind it.

"Viewing the books on the second floor costs one low-grade spirit stone per hour. You are not allowed to take the originals out of here. If you want to make copies of the contents, you will need to pay an additional copying fee of ten spirit stones per copy."

The old man's voice rang out, but Zhou Yuan didn't pay any attention to it. For his current wealth, what did one or ten yuan matter?

He casually tossed out three spirit stones!

"Yo..."

The old man was clearly surprised, not expecting that the young cultivator wouldn't be deterred by the high price.

Enter the second floor.

All that could be seen were two dark bookshelves, a dirty table, and a broken chair—that was all the family's possessions.

There are many yellowed old books on the bookshelf, and several bundles of tattered bamboo slips and two jade tubes whose original color is no longer discernible on the table.

An ordinary person might not have a strong reaction, but Zhou Yuan's eyes lit up at this moment.

"They're all old items..."

"If only I could take these old things away..." Zhou Yuan longed for it intensely.

Of course, he knew that the most valuable thing here was the two jade slips on the table!

One of them is the formula for the Foundation Building Pill, and the other is the formula for the Youth Preservation Pill!

The books and bamboo slips contained only basic pharmacological knowledge, which was of no use to him.

Zhou Yuan spent two hours reviewing the documents.

I also thought about it for a long time.

Finally, he made up his mind!

He walked downstairs with two old jade slips in his hand.

He remembered that in the original story, the old man was portrayed as extremely greedy.

"Mr. Xu, can I talk to you about something?"

Zhou Yuan took out two jade slips and placed them on the table in front of the old man, and smiled.

"No, not a single spirit stone can be missing!"

Before the old man could hear what Zhou Yuan was about to say, he shook his head violently, thinking that Zhou Yuan couldn't produce the spirit stones to make two copies of the jade slip.

"Elder Xu, you've misunderstood. I just want to take these two original jade slips with me. I can offer double the price..." Zhou Yuan quickly explained.

"Double?"

The old man hesitated for a moment.

I don't understand why Zhou Yuan insisted on taking the original document.

"That's right, I usually enjoy collecting old objects; I find these things full of charm!"

"What does Mr. Xu think?"

After Zhou Yuan finished speaking, he took out forty low-grade spirit stones from his storage bag and placed them on the table.
