After breakfast, they went out of yudingzhai with Mengling behind Yizhen Taoist. At this time, Li Yueer's master also came to yudingzhai. After meeting, they went to tianlongmen together.

Although a large number of people came to attend the exchange meeting, most of the people who came to Tianlong city were only qualified to participate in the auction. Some of them even had no sects. They had to come in to do some business in the shops or exchange with other people in private.

In this morning's exchange meeting, only some decent sects can be invited, so most people are not invited to see it.

Qin Yichen is also very curious. He wants to see the top one among the domestic immortals. He follows Taoist Yizhen to tianlongmen and goes straight to the test ground on the west side of tianlongmen.

From the outside, the testing ground looks like a round building similar to a yurt. It doesn't look big, and its diameter is more than ten meters. In any case, it can't hold nearly a thousand people. Luo Bingyan, who is walking beside Qin Yichen, sees an endless stream of people coming in from the entrance. He can't help but wonder: "master, this testing ground looks so small, Don't so many people even have a place to put their feet down? "

Qin Yichen smiles a little and explains: "generally, there are space arrays in this kind of place. It can open up more space in the limited space by using the array. It's similar to the principle of heaven and earth bag and storage ring. However, after the space array of heaven and earth bag and storage ring is formed once, the space does not need to rely on the spiritual power to maintain, but the defect is that the space is dead, And you can't store living things. "

With that, Qin Yichen said: "the space array used in the test field is not very deep. It's 18000 miles worse than the array on the storage ring. As long as it's opened, it will consume spiritual power continuously. It needs to be maintained with spirit stone continuously, but the advantage is that it can be large or small, and no creature or object will be affected in the space."

Luo Bing could not help sighing: "to maintain this kind of space operation, it should cost a lot of spirit stone, right?"

Taoist Yizhen laughs: "this kind of space has a great demand for spiritual power, and it's continuous. Even tianlongmen can't afford it. Therefore, it's just that the exchange conference will open the array these days. It's too wasteful to use it at ordinary times."

Luo Bing suddenly realized and nodded, exclaiming: "you are still a master with profound knowledge."

Taoist Yizhen couldn't help laughing: "the key point just now, Qin Yichen told you 90%, I just said one of them."

With that, Taoist Yizhen looked at Qin Yichen and couldn't help praising: "the disciples from the Da Yin sect are different. You can see the essence of things at a glance."

Qin Yi Chen modest smile, light way: "all is the teacher once taught, I also just keep in mind."

With that, everyone has arrived at the entrance of the testing ground. The two elders of tianlongmen are guarding the entrance. Seeing Taoist Yizhen, they greet him with fists.

After all, Taoist Yizhen is a local snake in the Kunlun Mountains. Moreover, he is old enough. It's not a loss for these elders to call him elder martial brother. There is a difference in his status, so his attitude is naturally polite.

The other side didn't care whether the other people who were accompanied by Taoist Yizhen were really Kunlun disciples, but when Taoist Yizhen said hello, they got out of the way and invited everyone in.

The crowd entered one after another, and Qin Yichen heard a burst of exclamation.

This exclamation comes from Luo Bing and others.

On the outside, it looks like a yurt. When I came in, I found that the space inside is comparable to the size of a medium-sized concert hall.

The whole interior space is still round. Like the concert hall, the stairs keep going down, and the lowest part in the middle is a round open space. Qin Yichen sees that there is a boundary array around the open space, and knows that it should be a test ground.

The boundary array is used to isolate the fluctuation of aura. In this way, the competition of experts will not affect the audience outside.

They all sat down in an area with good sight. Qin Yichen sat down next to Luo Bing when they were all seated. At this time, an old man in front of Qin Yichen turned his head, looked at Taoist Yizhen and said with a polite smile, "master Yizhen, I haven't seen you for many years!"

Taoist Yizhen looked at the man who looked back to greet him. After thinking for a long time, he suddenly patted his forehead and said with a smile, "it's Yunfei! I haven't seen each other for many years. How are you now

Xuantian gate?

Qin Yichen's brain was stunned, and he instantly remembered his experience when he was in Canada. When he killed the two immortals, he was not a disciple of xuantianmen? But their leader seems to be called Laozu. Who is Yunfei?

Qin Yichen doesn't know that Yunfei is the name of Laozu himself. The name "Laozu" is only used inside the Xuantian gate. With his strength, he never dares to call himself Laozu in the world of cultivating immortals. His real name is zuyunfei.

Zu Yunfei is a man who covers the sky at Xuantian gate, but when he goes out of Xuantian gate, especially in front of Taoist Yizhen, he is just a younger generation, and his accomplishments and even his Dan period have not reached.

"Master Yizhen." With an embarrassed smile, Zu Yunfei said, "the xuantianmen sect is no better than the Kunlun sect. The Kunlun sect has the Kunlun Mountains. We can only go to the freezing Changbai Mountain, which is the most difficult sect in China."

Qin Yichen sent a message to Taoist Yizhen and asked curiously, "master Yizhen, what's the origin of Yunfei?"

Yizhen Taoist replied: "he is the leader of Xuantian gate. His name is Zu Yunfei. Many years ago, he was a junior of a small generation."

Qin Yichen nodded and asked, "I heard that there is a man named Laozu in Xuantian gate. I don't know who he is. Have you heard of him?"

"Laozu?" Taoist Yizhen couldn't help laughing and said, "is this title too arrogant? In the world of cultivating immortals, it seems that no one dares to call himself the ancestor. However, if you say so, the ancestor should be Zu Yunfei. "

Qin Yichen laughs in his heart. Unexpectedly, when he attends an exchange meeting, he meets his old enemy. Fortunately, this guy doesn't know himself. Even if he sits in front of him, he doesn't know who he is. What's more, he kills his apprentice and takes away the iron spirit he wants to get.

At this time, Zu Yunfei asked with some compliments: "elder Yizhen, I've been looking for suitable materials to improve my flying sword recently. This time, my younger brother also brought more than 30 pieces of huilingdan, which are going to be sold at the auction to buy materials for refining flying sword. Have you heard about it? Are there any good materials for auction?"

Taoist Yizhen shook his head gently and said, "I haven't heard of that. I only heard that someone took out a lot of top-quality pills for auction. It's estimated that this should be the highlight of this year's auction."

Zu Yunfei's face flashed a trace of anger, damn it! In the past, if I told people in the industry that I had more than ten elixirs, the leaders of those big sects would be very polite to me and hope to make a deal with me. But now I'm not so good. I've managed to prepare more than 30 elixirs, but I was completely robbed of the limelight.

At this time, Taoist Yizhen thought of something and said, "by the way, it seems that there is a black iron essence to participate in the auction this time."

"Is it?" Zu Yunfei immediately asked, "how many do you know?"

Zuyunfei thought in his heart, could it be that he was robbed of xuantie Jing and took it back to participate in the auction? If so, this time in Tianlong City, I may be able to find the mysterious man who makes me hate until now.

At this time, Yi Zhen said: "it seems that I heard that there is only a piece of black iron essence less than the size of my thumb, and the price is very expensive. The transaction price should be more than one million spirit coins."

"What?"

Not only Zu Yunfei was extremely surprised, but also Qin Yichen was equally surprised. A piece of dark iron essence less than the size of his thumb could be sold for millions of spirit coins. Wouldn't his flying sword start with tens of millions?

What's more, the original dark iron essence has not been used up, and there is still a lot of surplus. If you take out a piece and sell it, I'm afraid it's more valuable than pills.

But think about it, Qin Yichen gave up the idea again. It's useless for him to ask for spirit coins. He can only use spirit coins as the price of exchange when he meets something he's interested in.

Zuyunfei in front of him is already mad. It's said that the former piece of black iron is much bigger than an adult's fist. Now, though it's the size of a thumb, it's worth more than one million spirit coins. Roughly speaking, he has at least passed ten million spirit coins!

Looking at Zu Yunfei's side face, Qin Yichen can see the fire on his face at the moment. He can't help sneering in his heart. Now Zu Yunfei can come here to participate in the exchange conference, which proves that he is still a righteous person in other people's eyes. However, xuantianmen is located in Changbai Mountains, and people of other sects don't know about xuantianmen.

However, Qin Yichen knows that xuantianmen is not a decent school at all. Zu Yunfei is not a decent person. He uses his own voodoo to control the vast majority of xuantianmen's disciples, and arranges them all over the world, so that they can help themselves to find treasures and materials for cultivation all over the world The means used are almost the same as those of heresy.

If you reveal his true features, I'm afraid his Xuantian gate will become a street mouse in the future, right?

At this time, the test hall is full one after another, and nearly 1000 people are sitting in it, waiting for the coming competition between the experts. At this exchange meeting, people are most interested in Mo Tianqiu, the leader of Qianshan sect. It is said that he has successfully broken through and entered the fourth level of jiedan period a few days ago, which is also one of the major sects of Zhengdao, He is the one with the highest accomplishments and the fastest breakthrough.

Even those who have entered the jiedan period feel inferior to Mo Tianqiu. After all, Mo Tianqiu's time is only half or more than half of them, and his future potential is bound to be much greater than theirs.
