With the Eight Immortals' magical treasures in hand, even a mortal like myself! Ha!

The old man in the gray robe rubbed his hands together and said with a smile, "It's not that I don't trust you, but could you please let me see your financial resources?"

Gu Qing tapped his hand on the edge of the table. As the saying goes, one should not flaunt one's wealth. He wondered how much he should reveal given his early Foundation Establishment cultivation level.

At this moment, Gu Qing used the Qi Concealment Technique to tighten his aura. To outsiders, he appeared to be only at the early stage of Foundation Establishment. Unless a Core Formation cultivator examined him, it would be difficult for even a Foundation Establishment cultivator with keen eyesight to discern Gu Qing's cultivation level.

After thinking for a moment, Gu Qing decided to show the gray-robed old man thirty mid-grade spirit stones first.

A cultivator in the early stages of Foundation Establishment has thirty mid-grade spirit stones, which should be neither too many nor too few, enough to complete the following transaction.

Thinking of this, Gu Qing did not hesitate at all and directly took out a storage bag and placed it on the table.

Seeing this, the gray-robed old man didn't stand on ceremony and directly checked the spirit stones in the storage bag. Upon seeing that there were thirty mid-grade spirit stones, the gray-robed old man immediately changed his attitude and said, "You're a very important customer. Please follow me, guest. What you want isn't on the fourth floor."

And so, led by the old man in the gray robe, Gu Qing went up to the sixth floor and then saw Madam Lan.

After several years apart, Madam Lan has become even more mature and charming with every smile and movement.

The gray-robed old man whispered a few words in Madam Lan's ear. Madam Lan nodded, then glanced at Gu Qing and said, "Fellow Daoist, this shouldn't be your first time visiting my Stardust Pavilion, right?"

"Hehehe, I have indeed come a few times. I am of ordinary appearance, I'm afraid Madam Lan doesn't remember me." Gu Qing did not deny it, his words were seven parts truth and three parts falsehood, making it difficult for Madam Lan to discern for a moment.

Madam Lan observed Gu Qing for a long time, but she really didn't remember such a person. She could only apologize and say, "I'm so sorry, I really don't remember you. I heard that you want pills and formations. I wonder what your requirements are for the formations?"

"What are the requirements for the formation? I want a formation that becomes more powerful the more investment is made, preferably one that can be set up quickly by one person." Gu Qing was quite looking forward to the formation.

It should be noted that Qi Yunxiao, with his Qi Refining cultivation, used formations to kill enemies of higher levels and even trapped a Core Formation Ancestor. Such achievements are dazzling anywhere.

Upon hearing Gu Qing's request, Madam Lan immediately thought of a formation and whispered a message to her maid.

The maid nodded after hearing this and slowly walked away. A moment later, she returned carrying a tray.

Upon seeing the tray being brought over, Madam Lan said, "This is the Lesser Three Array Formation. It has four array eyes. The more powerful the magical artifact placed in the array eye, the stronger the power it will unleash. It is an offensive array formation."

"If you have four top-tier magic artifacts, activating them would be enough to deal with a pseudo-core expert," Madam Lan explained.

"Oh, the more powerful the magic weapon you put in, the more powerful it becomes when activated. That's interesting. I wonder how many spirit stones this formation costs?" Gu Qing asked.

Madam Lan covered her mouth and chuckled, "This formation only costs three thousand spirit stones. If you want both the formation and the pills, I can sell it to you for six thousand spirit stones."

Six thousand spirit stones is equivalent to sixty mid-grade spirit stones.

Based on the annual salary of one spirit stone for a Foundation Establishment cultivator in Huangfeng Valley, that would be the salary for sixty years, which is quite a lot.

A single array formation costs three thousand spirit stones. Considering that Xin Ruyin gave Han Li several array formations before she left, Han Li really made a fortune.

Gu Qing hesitated after hearing this, as sixty mid-grade spirit stones were far beyond his budget.

That's enough to buy three top-tier magical artifacts, and even a set of them.

This made Gu Qingzhen really want to sell the medicinal herbs. Fifteen 500-year-old medicinal herbs could be exchanged for 100 mid-grade spirit stones, and the other party could also give her 40 spirit stones.

Of the four arts of formations, alchemy, weaponry, and talismans, Gu Qing seems to have only mastered alchemy. If only he had studied the art of talismans as well, he might be able to exchange them for pills and formations.

"I wonder if you accept pills?" Gu Qing suddenly asked. He had collected more than forty storage bags while he was escaping.

Among them, Core Formation cultivators have seven storage bags, Foundation Establishment cultivators have ten, and Qi Refining disciples have more than twenty.

Among them, the Qi Refining disciples had six Foundation Establishment Pills in their storage bags, plus the two Foundation Establishment Pills in Gu Qing's hand, making a total of eight. They could sell some of the Foundation Establishment Pills.

Madam Lan naturally gave an affirmative reply: "Yes, I will. May I ask what kind of pills you wish to sell, fellow Daoist?"

Gu Qing feigned hesitation, but finally took out two jade bottles and said, "Look, can these two bottles of pills be exchanged for the items in this transaction?"

Madam Lan was somewhat surprised and curious about what kind of pills were so valuable that she wanted to exchange them for an array and pills worth six thousand spirit stones.

Madam Lan reached out and took a jade bottle, then opened it. Instantly, the fragrance of medicinal pills and pure spiritual energy filled the surrounding space.

Upon a brief glance, Madam Lan exclaimed in slight surprise, "Foundation Establishment Pill?"

Unexpectedly, the other party actually took out a Foundation Establishment Pill. It should be noted that the Foundation Establishment Pill is a pill that is strictly controlled in Yuanwu Kingdom.

Foundation Establishment Pills are rarely available on the market, so it's no wonder that Madam Lan looked surprised when she saw them.

"Fellow Daoist, are you sure you want to exchange two bottles of Foundation Establishment Pills for the formation and the pills?" Madam Lan asked to confirm.

Gu Qing nodded and said, "I have already established my foundation, so Foundation Establishment Pills are useless to me. Let's trade them. There shouldn't be any problem with that, right?"

"Hehehe! That's no problem at all, fellow Daoist. I agree to this deal." Madam Lan seems to still have a lot of influence in Star Dust Pavilion; she made a decision on a deal worth several thousand spirit stones just like that.

In this way, Gu Qing exchanged two Foundation Establishment Pills for two pills that could improve his Foundation Establishment cultivation, as well as a set of Minor Three-Element Array.

After buying his things, Gu Qing didn't linger at Star Dust Pavilion and left immediately. On the way, recalling the previous transaction, he shook his head slightly. It seemed that directly exchanging pills wouldn't be a smooth path.

Because once the transaction amount becomes large, it is easy to attract the attention of others, and ultimately you will have to return to your own plan of cultivating spiritual herbs.

But this matter cannot be rushed. Even if there is planting, there must be spiritual fields. After all, the Purple Gold Flute does not produce spiritual herbs out of thin air, but needs to gather spiritual energy to nourish and promote their growth.

So now we need to find a place to stay temporarily, and it would be best if we could also open up a spiritual field.

This reminded Gu Qing of Xin Ruyin, who cultivated spirit tea. If she could cultivate spirit tea, she could probably cultivate spirit herbs as well. He just didn't know where that place was.

Thinking and thinking, Gu Qing left the market. As soon as he left, he noticed a pair of eyes watching him.

This made Gu Qing wary, thinking to himself, "Was I discovered so quickly?"

Or were they being watched by people sent by Stardust Pavilion?

With some doubts in her heart, Gu Qing quickened her pace and finally walked out of the market, preparing to fly away.

Then a cultivator in the mid-Foundation Establishment stage blocked Gu Qing's path.

"So it was you who stole our Qin family's thousand-year-old medicinal herbs?" The newcomer was none other than a Foundation Establishment cultivator from the Qin family.
