Dong Jianping was very efficient. Zhou Yang received his invitation the next day and learned that the exchange meeting would be held three days later.

Three days was not long. During Zhou Yang's time, he went up to the city to have a look. He released his flying sword to help attack the low-level monsters outside the city to attack the city defense array. The time was almost over.

With the opening of the city guarding array, the remaining garrison friars in Zhenyue fairy city have been fully enough to deal with the attack of monsters outside the city. The reason why the "beast tide" still doesn't disperse now is to surround Zhenyue fairy City, prevent the friars in the fairy city from going out of the city to support other fairy cities, and encircle and attack those monsters deep into the fairy world of Liuyun island.

Zhou Yang, these friars, can't go to the city to help now. No one will force them, because they have done their part in the previous battles.

On the evening of three days later, Zhou Yang took the invitation to an unlisted shop on another fairy mountain. Then, under the reception of the monks in the shop, he received a hooded hat, hat and magic weapon that could block the peeping of others' divine knowledge, as well as a black one-piece cloak and Magic weapon that could hide the magic smell of his body.

When he put on his magic tools and walked into a hall deep in the shop, he found that more than a dozen monks dressed like him had gathered here. When these people saw him coming in, they just looked at him through the silk curtain hanging from the hat, then took back their eyes and continued to close their eyes.

Seeing this, he also found a chair to sit down, closed his eyes and waited.

So when a few more people came in, the friar who gave them magic tools came in and looked at them and said, "the animal cart has arrived. Please come out and get on the bus."

Zhou Yang and others heard the speech and went out of the door. They saw that there was a van type animal cart enough to hold dozens of people. The spirit beast pulling the cart was actually a three-level inferior monster "Yufeng foal" that could fly against the wind. The friar driving the cart was also a friar after building the foundation with a hat.

"Please get on the bus. I'm responsible for taking you to the place where the exchange will be held."

An old voice came from the monk's mouth at the later stage of foundation construction, and the door of the animal cart immediately opened on both sides for Zhou Yang and others to enter.

When Zhou Yang and others entered the animal cart and sat down, the old man gently pulled the whip in his hand, and the two "Yufeng foals" hissed. The blue light on the horse's back flashed, and a pair of blue Lingguang wings had grown.

Then the two winged spirit beasts took a step, got up in the wind, took the animal cart straight up the blue clouds and flew to another place on the fairy mountain.

Because the carriage of the beast cart also has the function of shielding divine consciousness exploration, Zhou Yang and other people sitting in the cart do not know where they have been taken. They only know that when the beast cart lands again and stops stably, it is already in a courtyard shrouded by the magic array.

"Here's the place. Please get off and enter!"

The driver's voice sounded from outside the car, and the car opened again for Zhou Yang and others to get off.

After they got off the animal cart, they were led into a tunnel by a foundation building friar with a hat, and the animal cart flew out of the courtyard again under the driving of the driver. I don't know where it flew.

After walking about hundreds of meters in the tunnel with the guide, Zhou Yang and his party finally came to the venue of the underground exchange, an underground cave hall enough to accommodate hundreds of people.

In the underground cavern hall, except for a stone table that was obviously empty for the exchange friars to display their items, only two or three hundred futons were placed on the ground. At this time, 70 or 80 people had been seated in the underground cavern hall. After Zhou Yang came in, there were hundreds of people.

But Zhou Yang looked at the situation. Obviously, this was far from all the people invited to the underground exchange, so he could only find a futon to sit down and continue to wait like those who came first.

The exchange meeting was highly confidential. Even if he knew that Dong Jianping was also in the underground cave hall, he didn't want to find each other. I believe Dong Jianping thought so.

After waiting for nearly an hour, the number of people in the underground cave hall exceeded 200. This number has accounted for more than half of the existing friars in the foundation period in Yuexian city.

At this time, the last group of special participants came here. They were eight purple friars participating in the exchange meeting.

Six of the eight Zifu friars also carried identity concealing tools, with the exception of two.

Zhou Yang happened to know one of the two exceptional people, which was Jia Yunzhen, a monk of the purple house who had previously ruled him on the city wall.

"Thank you for taking part in the underground exchange organized by Laozao in your busy schedule. Laozao Tian Wenxuan, as the organizer of this exchange, whether you know Laozao or not, since all of you are here, it is to give Laozao face. Laozao also wishes all of you can get what you want at the next exchange and return with full load!"

"Well, I don't have much to say. The exchange meeting will begin now. I'm the first to step on the stage and give you a brick to attract jade!"

When Zhou Yang looked at Jia Yunzhen in surprise, Tian Wenxuan, another white haired old man who did not hide his identity, went to the only stone table in the underground cave hall, glanced at the people in the cave hall and slowly said his identity.

When Tian Wenxuan finished, he took out three jade boxes and put them on the stone table in front of him.

He opened and arranged the jade boxes one by one, and said in a low voice: "I have only three treasures here, namely, a fourth level medium demon pill, a fourth level spirit nourishing fruit, and a fourth level spirit ice Xuanshi. I give priority to exchange for the spirit things that help to knot the pill. If there are no spirit things, I only need to be able to provide accurate information about the spirit things, You can also choose one of the treasures other than the demon pill! "

When Zhou Yang looked around, he saw that the fourth level medium demon pill was only the size of an egg. It was round and emitting red magic light. It was obviously owned by a fourth level monster with fire attribute. This was the first time he saw this kind of spirit, and he couldn't help looking more at it for a while.

Then he looked at the other two spirits, soul nourishing fruit and ice Xuanshi.

The shape of soul nourishing fruit is like an apple. Its color is black and purple. It is full and dripping. People want to take a bite when they see it.

The ice basalt is a blue and white ore the size of a palm. The jade box containing the ore is made of a century old cold jade. Zhou Yang's divine knowledge shoots past, and a chill like the soul can be frozen suddenly comes out of the ore, frightening him to take back his divine knowledge and dare not see more.

Tian Wenxuan's accomplishments are already the ninth floor of the purple mansion. He has been preparing for the condensation of golden elixir for a long time. It is understandable to put forward this exchange condition now.

However, all the monks present turned their eyes when they heard him.

It is true that the three treasures Tian Wenxuan took out are not ordinary. Needless to say, the role of the fourth order demon pill is the best choice, whether it is used to refine the foundation pill or some pills that can greatly improve the cultivation of monks in the purple mansion period.

Soul nourishing fruit can help the monks who failed to open up the purple mansion recover their spirits quickly, or treat the spirits of the monks who were injured by accidents. It is also a rare treasure.

Compared with the previous two treasures, the ice basalt seems to be a bit worse, but if you refine the flying sword with this material, it can make the flying sword have the "freezing" effect. That is, after the fourth order monster is injured by the flying sword integrated with the ice basalt, the wound will also be frostbitten and difficult to heal.

However, these three treasures are precious, but there is still a gap compared with the treasures that can help knot Dan.

In particular, how many people are willing to exchange these holy things with others unless they are already in the golden elixir cultivation period or have more holy things?

Even if it's just news, few people are willing to let others know.

Therefore, although Tian Wenxuan's three treasures made many people greedy, none of them were exchanged in the end. He only shook his head regretfully, raised his hand, put away the jade box on the stone table, went to one side and sat down on an empty Futon.

As soon as he went down, another masked monk of purple mansion came up with him and said, "my cultivation is not as good as Tian Daoyou, and I don't have as rich wealth as Tian Daoyou. Here are some third-order talismans drawn by me in my spare time. You can either exchange them with spirit stones or take out the treasures I'm interested in, No problem. "

When the man finished, he took out three jade boxes and opened them on the stone table, revealing dozens of third-order talismans distinguished according to the grade of talismans.

This situation is completely opposite to Tian Wenxuan's previous situation. After communicating with the masked purple friar, a large number of friars in the foundation period came forward to exchange several third-order talismans with him. It was just a cup of tea, and all the talismans were exchanged.

Zhou Yang had no idea about this. Although the third-order talisman was good, it was not very attractive to him. The spirit stones and treasures on him should be used where they were needed more.

Next, several purple mansion friars came on stage and took out treasures for exchange. Most of them, like the friar who sold spiritual talismans, took out some things suitable for friars in the foundation period in exchange for spirit stones. Only a few or two people, like Tian Wenxuan, just wanted to exchange treasures they could use.

Zhou Yang looked at the treasure taken out by a friar of Zifu period. He wanted to exchange it for the eye-catching treasure several times, but he finally held back, because he was not sure whether there would be better and more exciting treasures in the future.

After waiting for less than half an hour, he finally waited for a treasure that he couldn't help but want to sell.

"I still have three extra foundation pills here. I want to exchange them for Millennium blood ginseng, seven leaf purple heart grass, fourth order velvet antler and Earth Dragon earthworm... If any Taoist friend has the above-mentioned spiritual objects in his hand, whether he wants to exchange for foundation pills or other pills for third and fourth order refined cultivation, I can exchange them for sound transmission!"

In the underground cave hall, as the penultimate monk of Zifu period came to the stage and took out his treasures, many participating monks, including Zhou Yang, stared at the small medicine bottle on the stone table.
