The stall owner introduced to him, "You only need five hundred spirit stones or ten foundation building stage pills to exchange." ”

Lu Yuan was a little embarrassed, after all, the pill of the foundation building period was not superfluous for him, and the spirit stone was not readily available.

But he was attracted to the slate, and after weighing it in his mind for a moment, he decided to fight for it.

"Can I exchange two hundred spirit stones plus a few rare spirit grasses for it?" Lu Yuan said tentatively.

The stall owner suddenly frowned, as if he was not satisfied with Lu Yuan's request.

Seeing this, Su Liyan couldn't help but interject: "Lord stall owner, I have known this Lu master for a long time, and he has never owed anyone else. ”

After listening to Su Liyan's words, the stall owner finally loosened his brows.

"Okay, two hundred spirit stones plus three rare spirit grasses." The stall owner compromised.

Lu Yuan smiled slightly, he knew that he had won the trade.

After completing the transaction, Lu Yuan left the stall holding the relic slate.

He was excited and satisfied: it was a successful transaction, and he traded fewer resources for something precious.

Just as Lu Yuan was about to leave, he suddenly felt that someone was watching him.

He turned his head to look, just in time to see a figure slowly approaching.

"Master Lu, Shaoxia, where did you get this relic slate?" The man's face was gloomy and serious.

Zi Xi'er had already stood alertly in front of Lu Yuan, and gently pulled out the sword hanging from her waist.

Su Liyan stared at the person and said vigilantly: "We are in exchange for it according to the trading rules, what's the problem?" ”

The man smiled slightly and introduced himself, "I am a close envoy of the Heavenly Wind City City Lord's Mansion, and I have come to investigate the source of the relic slate. ”

"Are you willing to cooperate with the investigation?"

Lu Yuan was not afraid of this secret envoy, but felt a hint of challenge and excitement.

He smiled and said, "In that case, please ask the secret envoy to come with us." ”

Zi Xi'er and Su Liyan glanced at each other, and then followed behind Lu Yuan.

The trio and the envoy walked into a quiet and secluded corner.

At this time, the sky gradually became gloomy, as if to hint at the coming change.

"Master Lu, please hand over the relic slate in your hand." There was a bit of pride in the secret envoy's voice.

Lu Yuan put away his playful smile and said calmly: "This relic slate is not something that will be easily handed over to others, if you want to take it, you need to rely on strength. ”

Zi Xi'er and Su Liyan immediately stood beside Lu Yuan, and released a powerful momentum in tacit understanding.

A hint of surprise flashed across the envoy's face when he saw the reaction of the three of them.

He didn't expect that these seemingly ordinary cultivators would have such a strong strength.

The secret envoy looked embarrassed when he heard this: "I am only carrying out the task according to the order of the city lord, and I have no power to dominate it. ”

This sudden incident made Lu Yuan have more speculation and wariness of Modi.

He decided to keep this dragon prince on high alert to avoid any mistakes in the future.

Lu Yuan turned his head and saw Wu Qingyun hurriedly walking towards him, with a little anxious look on his face.

"Master Lu, come and see!"

"Jiang Liuyun Gongzi announced over there that he was going to exchange precious items!"

Wu Qingyun shouted as she pointed to the crowd in the center of the market.

Lu Yuan followed her guidance and saw Jiang Liuyun Gongzi standing in front of a stall, holding a piece of jade that exuded a strong immortal aura.

The people around stopped to watch, curious.

"Humph!"

"These things are only qualified to belong to the elites of each family, and they are really superior in exchange."

Jiang Liuyun said mockingly.

Jiang Liuyun Gongzi had a smug smile on the corner of his mouth, he believed that the treasure jade he was carrying would be able to attract the favor of other Xiuzhen families.

Lu Yuan pondered for a moment and walked to Jiang Liuyun's side, and also took out the relic slate.

"Young Master Jiang, are you willing to exchange the treasure jade in your hand with my relic slate?"

Lu Yuan asked lightly.

Jiang Liuyun Gongzi turned around, his eyes fell on the relic slate in Lu Yuan's hand, and he was stunned for a moment.

"What are you?"

"Relic slate?"

A hint of surprise flashed in Jiang Liuyun's eyes.

"That's right, this is an extremely precious cave treasure with infinite miraculous effects."

"If you're interested, we can make an exchange."

Lu Yuan's voice was calm and firm.

Jiang Liuyun Gongzi's eyes flickered slightly, and he fell into thought.

After all, he was confident that the treasure jade in his hand would not lose to anyone, but he couldn't let go of this opportunity easily.

Under the expectant gaze of everyone, Jiang Liuyun Gongzi finally nodded.

"Good! Let's make an exchange! ”

With the consent of Jiang Liuyun Gongzi, the two quickly completed the exchange.

When the relic stone slab and the treasure jade were handed over to the other party, both exuded powerful immortal qi and spiritual power fluctuations.

Wu Qingyun looked at the scene in front of her, her eyes full of amazement and admiration.

She knew that Master Lu was known for his shrewdness and decisiveness in and around Tianfeng City, and she didn't let her down.

Just as the transaction was completed, Zi Xi'er and Su Liyan also gathered beside Lu Yuan and were escorted by Mo Di.

"Master Lu, I just saw that you and Jiang Liuyun Gongzi completed a transaction."

Zi Xi'er raised her eyebrows slightly.

Lu Yuan nodded and explained to them, "This is an opportunity, the treasure jade carried by Jiang Gongzi is not of practical value to us, but the relic stone slab plays an important role in our cultivation. ”

"So, I decided to make an exchange."

Su Liyan listened to it and said with a smile: "Master Lu really has a unique vision, and he has obtained greater benefits in this transaction. ”

Modi stood silently and watched the crowd communicate.

He felt that his judgment of Lu Yuan was becoming more and more accurate, and this person was by no means ordinary.

After everyone celebrated briefly, Lu Yuan turned to look at the secret envoy again.

"Now that the deal is complete, could you please explain to us what you said about the investigation?"

The envoy nodded, and began to explain to the four of them: "Here's the thing, there have been frequent thefts of cave treasures recently, and we suspect that someone is peddling counterfeit goods in the city. ”

"Therefore, an envoy from the mansion came to investigate."

"The relic tablets in your hands have caught my attention."

After hearing this, everyone had some enlightenment in their hearts.

Lu Yuan smiled slightly and said, "In that case, of course we will fully cooperate with the secret envoy to investigate." ”

As his words fell, the envoy felt that things were going well.

I didn't expect that this investigation would still be able to get the cooperation of this group of cultivators.

Wu Qingyun, a female monk on the side, looked at the scene in front of her, her eyes full of amazement and admiration. (End of chapter)
