Just when Ye Feng and Gu Niannu comprehended the Tai Chi Formation, the flying treasure ship of the Purple Rock Sect finally arrived at the place where the Taiyi Sect was located, the Thunder Ancient City!

The ancient city of Thunder is located in the center of Thunder Daze, which stretches for thousands of miles, covering the vast primeval jungle, and the sky is filled with thunderclouds that have not dispersed for thousands of years, and the crackling thunder echoes in the sky.

Even though it doesn't rain, it's amazing how thunder strikes all the time.

The scale of the Thunder Ancient City is huge, and even if the flying treasure ship is still hundreds of miles away from the ancient city, you can see the ancient city. What's even more amazing is that the thunder in the sky seems to be attracted by some strange force, like a waterfall falling from the sky, flowing into the center of the ancient city.

When the flying treasure ship flew into a square in the Thunder Ancient City, Ye Feng and Gu Niannu walked out of the cabin and came to the deck. At the same time, Shi Qian and Kou Shuang, as well as the rest of the people from the Ziyan Sect, also walked out of the cabin.

At this moment, Mr. Tianjing and the yellow-faced and thin-skinned old man got up at the same time, they smiled and nodded at Shi Qian and the others, and then flew off the treasure ship, and not long after, they disappeared into the flow of people on the street.

After the two old men left, Shi Qian also led everyone to get off the treasure boat and walked towards the center of the ancient city, and soon everyone arrived at a mansion with a plaque that read: Moon Worship Villa.

Each of the four major forces that came to the Thunder Ancient City had a mansion, which was enough to accommodate thousands of people. The Taiyi Sect is the number one force in the Heavenly Desolate Domain, how can the residence they arranged for the four major forces be shabby?

Gu Niannu also followed Ye Feng and the others into the Moon Worship Villa, Shi Qian didn't know Gu Niannu's true identity, but he knew that Gu Niannu was a soul master, so he didn't say anything, after all, it was not a bad thing for the Ziyan Sect to be able to make friends with a soul master.

After entering the Moon Worship Villa, everyone chose a room and stayed in it.

The Five Factions Contest didn't start until two days later, and during this time, everyone could practice in the Moon Worship Villa, or they could participate in the trading meeting on the trading street that went to the Thunder Ancient City.

......

Just when Ye Feng and the others were staying in the Moon Worship Mountain Villa, in the woods outside the Thunder Ancient City, Fu Xuan appeared and turned into a teleportation array.

Whoosh whoosh ......

Black shadows flew out of the large array, and there were hundreds of people, all dressed in black robes.

"This time, our mission is to find out the whereabouts of the fifteen elders, have you all remembered?" said the black-robed man at the head.

The rest of the black-robed people nodded, and one of them suddenly sneered: "The fifteenth elder has been missing for many years, but I didn't expect to be trapped by the Taiyi Sect." This time, we not only have to rescue the Fifteen Elders, but also destroy the Taiyi Sect!"

"Before we find out the whereabouts of the Fifteenth Elder, we can't act rashly, and the Fifteenth Elder must not be fine, because he has something very important on him. "The black-robed man is the leader.

The rest of the black-robed people nodded one after another.

"Let's go!" The black-robed people led by him rushed out of the woods and headed straight for the Thunder Ancient City, followed by the rest of the black-robed people.

......

At the same time, in the Thunder Ancient City, Ye Feng and Gu Niannu had already left the Moon Worship Mountain Villa and rushed towards the trading hall.

Although Ye Feng had a lot of treasure pills on his body, the speed of devouring the treasure pills to increase blood qi was too slow, so Ye Feng needed a large amount of demon pills so that he could increase blood qi as soon as possible. There must have been a large number of demon pills on the trading street in the Thunder Ancient City, so Ye Feng left the Moon Worship Mountain Villa and headed to the trading hall.

Soon, Ye Feng and Gu Niannu entered the trading street, and there were many people setting up stalls on the trading street, and many of them were selling demon pills.

Ye Feng bought the demon pill without hesitation, and then continued to walk into the depths of the trading hall, almost all the demon pills he encountered along the way were bought by him.

Suddenly, the news that someone had bought the demon pill in large quantities spread throughout the trading street, so many people took the initiative to find Ye Feng and sold the demon pill to Ye Feng.

Not long after, a middle-aged man found Ye Feng and Gu Niannu, and said with a smile: "In Xia Qin Lei, the auctioneer of the Purple Moon Chamber of Commerce, I heard that the two of you want to buy demon pills, and my Purple Moon Chamber of Commerce has a lot of demon pills, I wonder if the two of you are interested?"

"I wonder if your Chamber of Commerce has a demon pill for Divine Power Realm demon beasts?" Ye Feng smiled.

"As long as a friend is willing to buy it, even the demon pill of the demon beast of the Mixed Yuan Realm has it. Qin Lei smiled.

"Lead the way!" Ye Feng said with a smile, the person he lacked the most now was the demon pill of the Divine Power Realm and the Divine Courage Realm demon beast, if there was a demon pill of the Demon Beast of the Mixed Yuan Realm, it would be even better.

"Please come with me, two of you!" Qin Lei smiled and turned to lead the way.

Ye Feng and Gu Niannu glanced at each other and followed.

Soon, Qin Lei took Ye Feng and Gu Niannu to the Purple Moon Chamber of Commerce.

After entering the Purple Moon Chamber of Commerce, Qin Lei looked at Ye Feng and Gu Niannu and said with a smile: "How many demon pills do you need, what level?"

"How many can you come up with?" Ye Feng asked with a smile.

"Thirty Demon Pills of Divine Power Realm Demon Beasts, Twenty Demon Pills of Divine Courage Realm Demon Beasts, and one Demon Pill of Mixed Yuan Realm Demon Beasts, I don't know if my friends can accept it?" Qin Lei smiled, he had enough Demon Pills, he only shot Ye Feng and the two of them did not have enough Yuan Stones.

"I don't know how many yuan stones are needed for these demon pills?" Gu Niannu said with a smile.

"Thirteen million lower grade Yuan Stones!" Qin Lei smiled.

"We bought it. Ye Feng said with a smile.

"Hehe, my friend is really refreshing!" Qin Lei smiled: "Are the two of you interested in participating in the underground trading conference?" If you are interested, I can arrange for the two of you, and after the two of you participate in the trading conference, we should have prepared the demon pill." ”

"Underground Trading Conference?" Ye Feng's face changed slightly.

Qin Lei saw that Ye Feng didn't know about the underground trade fair, and hurriedly told Ye Feng about the underground trade fair.

It turned out that the so-called underground trade fair was to wear a mask, hide your identity, and then be organized by the Purple Moon Chamber of Commerce, and several people, or even a dozen people, would hold a transaction together to exchange treasures for each other.

After listening to Qin Lei's explanation, Ye Feng nodded with a smile, he was very willing to participate in this kind of underground trade fair.

Immediately, Qin Lei instructed a subordinate to prepare a demon pill for Ye Feng, and immediately after, he gave Ye Feng and Gu Niannu a mask and a set of black robes respectively. After Ye Feng and the others put on black robes and masks, Qin Lei led the way and led Ye Feng and the others into a dark hall.

There were two rows of chairs in the hall, eighteen in each row, almost full, leaving only four seats.

Ye Feng and Gu Niannu sat down on two of the seats, while Qin Lei walked to the top of the hall, looked at everyone and said with a smile: "You guys have any good things, even if you take them out, I believe that no one dares to move any crooked thoughts, although my Purple Moon Chamber of Commerce is not as good as the Jingwu Chamber of Commerce, but there are also masters who surpass the Mixed Yuan Realm." ”

"The Purple Moon Chamber of Commerce actually has an existence beyond the Mixed Yuan Realm......" Ye Feng's eyes flashed, with a strong person who surpassed the Mixed Yuan Realm, the strength of the Purple Moon Chamber of Commerce should not be underestimated.

"Hehe, if someone dares to snatch it, without the Purple Moon Chamber of Commerce, we will also kill him. A few people laughed.

"Ladies and gentlemen, I came here this time to buy a refining material, this refining material is called Taiyi Lei Mu, I think you should have heard of it. If any of you have Taiyi Thunderwood, you are willing to come up with a set of martial arts. ”

The person who spoke was opposite Ye Feng, his voice was a little old, it seemed to be an old man.

"I don't know what grade of martial arts your Excellency is talking about?" someone suddenly asked.

"It should be a ground-level martial art!" the old man's voice sounded again.

"Should?" Many people suddenly laughed, what does "should" mean ground-level martial arts?

"That set of martial arts was discovered by the old man in an ancient ruin, the first three layers are missing, and there are three layers behind, that is, there are six layers in total. Although the old man only got the fourth weight, he also benefited a lot. The old man said.

"Only the fourth level?" Many people ridiculed, there are a total of six martial arts, and only the fourth level has a fart!

"Old man, with only the fourth level of martial arts, how powerful can it be?" someone mocked.

"That set of martial arts is a top-grade martial art of the ground level, even if it is only the fourth, the power is far beyond most of the high-grade martial arts!" said the old man.

"Ground level top grade!" Everyone finally changed color, the ground level grade martial arts, even if they are fragments, are very precious, and the value even exceeds some human level grade martial arts.

You must know that even the five major forces do not have top-grade martial arts!

"Old man, I don't know what type of martial arts you are talking about?" everyone looked at the old man.

"That's a set of body-like martial arts, called 'Phantom Trace'!" the old man said slowly.

"Phantom Mystery Steps!" Ye Feng was shocked in his heart.

"Brother Ye, what's wrong with you?" Gu Niannu suddenly asked Ye Feng.

"I have the first triple of "Phantom Trace"!" Ye Feng stabilized his excitement and transmitted the voice to Gu Niannu.

Gu Niannu's face changed, she couldn't keep calm anymore, if Ye Feng could get the fourth weight, the power of "Phantom Trace" would definitely increase greatly!

Suddenly, someone asked: "The first two, or even the first three are very sure of the foundation, if there is no first three, even if you get the fourth one, it's probably useless, right?"

"That's right, if it's other offensive martial arts, maybe you can't exert some of your power without the first three, but the body martial arts are different. ”

"Old man, the reason why you are willing to take out this set of martial arts is probably because it is chicken ribs, right?"

Everyone's interest in "Phantom Shadow" was greatly reduced.

The old man smiled awkwardly and said, "If you really have Taiyi Lei Mu, you will be willing to take out an additional five million yuan stones!"

Ye Feng was in a hurry, he definitely couldn't watch his martial arts fall into the hands of others, but he didn't have Taiyi Lei Mu, so there was nothing he could do.

Gu Niannu couldn't help but feel anxious for Ye Feng, because she knew the importance of the fourth martial art to Ye Feng.
