A few days later, in the evening, Tang Mian slowly floated down from the cave mansion and landed at the gate of Lingyuan City. But at the time of a pillar of incense, Mi Zhen hurried out of the city gate.

"Tang Daoyou is really punctual. ”

Mi Zhen smiled and walked in front of Tang Mian, and after the two saluted each other, the former patted the storage bag, and a talisman appeared in his hand and handed it to Tang Mian.

"This talisman is a voucher to enter the exchange meeting, please keep it away. ”

Tang Mian glanced at the talisman and immediately put it in the storage bag.

At this time, Mi Zhen took out a hat out of nowhere and put it on his head, and then used his flying technique to float up and fly towards the outside of Lingyuan Valley.

Tang Mian smiled slightly when he saw this, and also put on a black hat and flew behind Mi Zhen, and the brightly lit Lingyuan City was getting lower and lower under his feet.

After flying for about a quarter of an hour, Mi Zhen took Tang Mian to the top of an empty plain. The two slowly landed on the ground, and the former took out the talisman from the storage bag, and after pinching a simple trick, the talisman glowed.

At this moment, a white formation suddenly appeared on the plain, which was still empty, and an ordinary-looking man in black walked out of the formation.

"Senior, please come in. ”

The man in black saw the talisman in Mi Zhen's hand and got out of the way, but stopped Tang Mian.

"This fellow Daoist, this exchange meeting is only allowed to be attended by monks in the foundation building period. ”

The man in black saw Tang Mian's cultivation at a glance, and he was a little surprised between his eyebrows, obviously he didn't expect that a Qi Refining Stage cultivator would appear here.

Tang Mian was not annoyed at all, and slapped the storage bag with one hand to show the talisman that Mi Zhen gave him, and the man in black respectfully got out of the way as soon as he saw the talisman.

Afterwards, Tang Mian and Mi Zhen stepped into the white vast magic circle one after another, and after entering the formation, Tang Mian felt a wave of dizziness, and when he opened his eyes, he found himself in a narrow cave.

"Tang Daoyou, please. ”

Yajine, wearing a hat, made a gesture of please, and walked towards the light in front of the cave.

Just a few dozen steps away, the narrow cave suddenly opened up, and a wide cave with bright lights and loud voices appeared in front of Tang Mian's eyes.

The cave is very large, and the roof of the cave is inlaid with some kind of bright ore that reflects the cave as if it were daylight. The floor of the cave was very flat and dry, with tables and chairs scattered everywhere, and many monks had already taken their seats, most of them wearing masks, hats, and other magic weapons to block the detection of divine sense.

The appearance of Mi Zhen and Tang Mian did not attract too much attention, in order to avoid unnecessary trouble, Tang Mian performed the Breath Gathering Technique, as long as the monks in the foundation building period here did not intend to investigate, they generally could not see his cultivation.

Led by another black-clothed monk, the two sat down in a more secluded corner, with all kinds of fruits and snacks on the table, almost making Tang Mian forget for a moment that he was in a nameless cave.

After half a cup of spiritual tea was down, Tang Mian and the eyes of the foundation building period monks were attracted by a short old man with white beard. The short old man stood on a high platform built in front of the crowd and bowed to the monks around him.

"Welcome all Taoist friends to participate in this exchange meeting. The old man touched his beard and smiled slightly, "This exchange meeting is still the old rule, you can only barter the treasures and bring them to the stage to display, and those who can accept the exchange of spirit stones will be handed over to the old decay auction, and the one with the highest price will get it." ”

The short old man was crisp and neat, and he made the rules clear in a sentence or two. As soon as he finished speaking, some of the monks stepped forward and climbed onto the high platform.

"Fellow Daoists must also know the goods, hundreds of years of fire Ganoderma lucidum, exchange for a century-old water jade bamboo or ice stamen. ”

The person who spoke was wearing a white mask and standing on a high platform, and at some point a palm-sized red fire-colored lingzhi appeared in his hand, and the cave immediately diffused a rich fragrance of elixir, which made people feel refreshed for a while.

"Daoist friends need water-attribute elixir, right? I wonder if the hundred-year-old condensing water grass can be exchanged?"

As soon as the fire lingzhi came out, someone immediately moved, this was obviously not an ordinary elixir.

The white-masked monk thought for a moment, then shook his head and said:

"Although the price of the hundred-year-old condensing water grass is expensive, I can still buy it by spending more spirit stones, and my fire Lingzhi is not easy to find. ”

Tang Mian sat on the chair and looked at the fire lingzhi, in fact, this fire lingzhi was quite useful to him. For him, who possessed a fire attribute spiritual root, a hundred-year-level fire spiritual mushroom could help him enhance his spiritual root qualifications. And if it is refined into an elixir, it can help the monks in the foundation building period to increase their longevity.

At this time, one of the monks hesitated to stand up and showed the one hundred and fifty-year-old water jade bamboo in his hand, which made the eyes of the surrounding monks widen.

The transaction was finally completed with the exchange of fire lingzhi and fifty medium-grade spirit stones for water jade bamboo, and the two sides took what they needed and were happy.

"Ahem, I'm still poor. ”

Tang Mian sighed, today is considered to be a rise in knowledge.

"The exchange here strictly prohibits the use of divine sense detection, and everyone doesn't have to worry about being recognized, so they are willing to exchange good things. ”

Mi Zhen secretly said to Tang Mian.

Tang Mian nodded, and then set his eyes on the high platform. With the fire Ganoderma lucidum as a foreshadowing, the atmosphere of the exchange meeting is hot.

Afterwards, the monks went up to the high platform one after another to display all kinds of treasures, such as pills, magic weapons or maps, and even had the experience of the monks of the Jindan period, which once caused everyone to rush crazy.

"Tang Daoyou, is there any treasure that needs to be exchanged, why don't you go up and try it?"

"If you are not satisfied with the Taoist, there is really something. ”

Tang Mian smiled, and after giving a salute, he stepped onto the high platform with his robe, and took out a dark golden metal magic weapon, which was the golden earth array array plate that had been refined not long ago.
