Mu Feng and Ling Shuang'er walked in the temporary trading ground, their eyes also swept over the surrounding stone platforms, many of which made Mu Feng also covet them, but these were not what he urgently needed, so he didn't make a move.

Now, in addition to the 10,000 Xuanyang Stones, plus the pills he scavenged in the Nameless Cave Mansion and Teng Rong, the Xuanli Pill alone has a million, and it is worth a lot of money.

However, the people who trade here are generally not coming for Xuanli Dan. Most of them are from middle and high-level dynasties, and there is no shortage of Xuanli Pills on their bodies, they just want to trade treasures that meet their hearts here, so they generally barter and rarely exchange Xuanli Pills.

Mu Feng walked slowly, Ling Shuang'er was interested in Lingbao, and she was also temporarily separated from Mu Feng and went to the place in the Lingbao area, leaving Mu Feng alone in the material area.

It's just that Mu Feng didn't see the two materials needed to control the black puppet along the way, these two materials are called Impermanence Spirit Sand and Golden Fetal Ice Stone, which are one of the important materials to drive the black puppet, and they are also relatively rare.

"Brother, why don't you come and take a look. Next to the stone platform on the side, a gray-clothed young man greeted Mu Feng and said.

When Mu Feng heard this, he also swept his gaze towards the stone platform of the gray-clothed young man, only to see that there was no one next to the gray-clothed young man's stone platform, and on the stone platform, there were more than ten tattered black bumps.

It is no wonder that the stone platform of this gray-clothed young man is empty, these more than ten black bumps are not only not good-looking, but also exude a peculiar smell, not only do not look like treasures, but like stones fished out of the latrine, which makes people stay away.

However, when Mu Feng's gaze swept over these black bumps, the runes in his right palm turned hot. Let Mu Feng's heart move, he slowly walked to the stone platform of the gray-clothed young man.

"What are these?" asked Mu Feng with interest, pointing to the dozen or so black bumps.

When the gray-clothed young man saw that Mu Feng really came over to ask, his eyes suddenly lit up, and he said enthusiastically: "These are all I found from an ancient tomb, and I can't figure out what they are, but they should also be extraordinary." ”

Facing the only customer who came to inquire, the young man in gray was extremely enthusiastic, but when it came to the back, he was also a little lacking in confidence. The strength of this gray-clothed young man was only in the middle stage of the Divine Realm, and these were the ones he found in an ancient tomb on the second layer of the Qingcang Assessment Realm. But he couldn't figure out what these things were, and what they were for.

Mu Feng picked up a piece of black pimple at random, put it in his hand and weighed it, these black pimples were not gold or stone, and they looked extremely heavy in his hand.

Mu Feng tried to use his soul power to find out what this black bump was. It turned out that this soul power could not penetrate at all.

Mu Feng's brows furrowed slightly, if it weren't for the rune in his hand that reacted. He may have abandoned him like others.

"What is this value?" Mu Feng smiled. Asked.

"The fifth-level Qingcang Seal can be exchanged for all of these things. The young man in gray said.

Mu Feng's eyes glanced lightly, and he saw that the Qingcang Seal in the hands of this gray-clothed young man was only level four, and he also understood that he would exchange these black pimples for a fifth-level Qingcang Seal.

With the strength of this gray-clothed young man in the middle stage of the Divine Realm, it was indeed a little difficult to obtain the fifth-level Qingcang Seal to pass the second level, plus he didn't know if these black bumps were treasures. That's when I took it out to try my luck.

Just now, the gray-clothed young man happened to see the fifth-level Qingcang Seal in Mu Feng's palm, so he tried to stop Mu Feng, and to his surprise, Mu Feng really stopped and came to his stone platform.

But he was also surprised. The aura emanating from this Mu Feng's body had only reached the cultivation of a half-step out of the gods, and he actually possessed a fifth-level green seal.

Mu Feng pondered for a long time, nodded at the gray-clothed young man and said, "I want these stones." ”

"Okay, buddy is really refreshing!" The young man in gray was a little overjoyed, and hurriedly said, as if he was afraid that Mu Feng would regret it, he stretched out his hand.

Mu Feng also stretched out his palm, although he slaughtered many demon beasts last night, he still did not raise the level of the Qingcang Seal to level six, the reason is also extremely simple, each level of the Qingcang Seal is raised, the energy required is extremely great.

Mu Feng defeated a mid-stage Xiaocheng powerhouse in the Divine Realm in the Phantom Killing Array, and only barely raised the Qingcang Seal to level four, but even if he killed a hundred mid-stage Xiaocheng powerhouses out of the Divine Realm, it would be difficult to raise the level of the Qingcang Seal to level five.

Unless you have the strength to kill a mid-stage Great Perfection powerhouse out of the God Realm or a small powerhouse at the peak of the God Realm, you can only raise the Qingcang Seal to level five.

This is also the Qingcang Mansion to prevent the personnel participating in the assessment from being opportunistic and not enterprising, and the establishment of the Qingcang seal level promotion is also a great incentive for the people who participate in the assessment, in order to be able to pass the assessment, and constantly improve their own strength.

The green cangyin in Mu Feng's palm swept out a blue light, and drilled into the green cangyin of the gray-clothed young man, the latter's green cangyin instantly became brighter, and a "five" character slowly emerged, while Mu Feng's Qingcang seal became dim, and the "five" character gradually changed to "four".

"Thank you, brother!" the young man in gray said gratefully, and gathered the more than ten black bumps in front of Mu Feng.

The fifth-level Qingcang Seal is not too difficult for Mu Feng to obtain now, so he doesn't mind too much.

Putting the more than ten black bumps into the Void Stone, Mu Feng no longer paid attention to the ecstatic gray-clothed youth, but continued to walk forward.

The owner of the several stone platforms next to the gray-clothed young man looked at Mu Feng with strange eyes, the level of the Qingcang Seal in the second level requires level five, if Mu Feng does not raise the Qingcang Seal to level five in the next time, then he will be eliminated directly.

If that's the case, it will be in exchange for the qualifications of the disciples of Qingcang Mansion for these more than ten pieces of black bumps that I don't know what to use, which will be a loss to my grandmother's family, and only a fool will do it.

Today's Mu Feng, in the eyes of the owners of those stone platforms, is this kind of fool. In this place now, everyone is not weak, and it is not easy to snatch the Qingcang Seal from others. Of course, the young man in gray just now was an exception.

"What the hell is this?" Mu Feng muttered in his heart, shook his head after thinking for a while, and stopped thinking about it so much, and then walked around the temporary trading grounds.

During this period, he also went to the elixir area to buy some medicinal materials used to refine the fifth and sixth grade pills, these medicinal materials are not rare, but they are also very valuable, and he also paid the price of 100,000 Xuanli pills and some other medicinal materials to buy those medicinal materials.

Mu Feng had finished walking around most of the temporary trading venues, and seeing that there was nothing that could arouse his interest, he went to find Ling Shuang'er and prepared to leave.

At this time, Mu Feng's eyes were suddenly attracted by an item on a stone platform.

The object was a golden stone, crystal clear, shaped like a newly-formed baby, and on the surface of the stone, there was a faint cold aura emanating from it, making people know at a glance that it was not ordinary.

Golden Fetal Ice Stone!

A material that he was looking for suddenly appeared in front of him, which made Mu Feng extremely happy, so he walked to the stone platform, pointed to the golden fetus ice stone and said, "What is the price of this?"

Behind the stone platform, there was a young man in red with a lazy face, and in his slightly spread left palm, Mu Feng saw a "seven" character.

Seventh-level Blue Sky Seal!

"Whatever, as long as you come up with something that matches my heart. The young man in red glanced at Mu Feng and said lazily, and the young man in gray who was enthusiastic just now were simply two extremes.

However, this is also determined by strength, the seventh-level Qingcang Seal represents strong strength, and it is also much tougher in dealing with people and things, and the key is to have strong capital.

Mu Feng smiled slightly, and was not annoyed by the attitude of the young man in red, but now in his Void Stone, except for Xuanli Dan and Xuanyang Dan, there are no valuable treasures, and he really doesn't know what to exchange for for a while.

Seeing Mu Feng's hesitant look, the young man in red glanced at Mu Feng coldly and said, "If you don't buy it, don't come to make trouble, get out!"

Looking at the appearance of the young man in red, Mu Feng understood that the other party mistakenly thought that he was here to entertain him, so he was a little angry, but for the attitude of the young man in red, Mu Feng didn't mind, genius, who doesn't have a temper!

"I don't know if I can buy it with Xuanli Pill?" Mu Feng asked lightly.

"Don't sell, don't sell. When the young man in red heard Mu Feng say this, a trace of annoyance flashed in his eyes, and he waved his hand and said.

"Hey, Mu Feng, what are you doing here?" There was a nice voice like a stream flowing lightly next to him, who else would it be if it wasn't Ling Shuang'er?

Mu Feng pointed to the golden fetal ice stone on the stone platform, and said helplessly: "I want to buy it, but unfortunately I can't buy it with Xuanli Dan." ”

"Say it earlier!"

Ling Shuang'er glanced at Mu Feng and said disdainfully, and as soon as her jade hand flipped over, a three-foot long sword with a mid-grade spirit treasure appeared in her palm, and then threw it on the stone platform.

The young man in red picked up the three-foot long sword, looked at it carefully, and found that although this long sword was a mid-grade spiritual treasure of the Xuan Rank, the spirituality it exuded was almost as good as the high-grade spiritual treasure of the Xuan Rank.

"Well, it shouldn't be a loss to exchange this sword for your stone. Ling Shuang'er said with a big grin, looking like she was rich.

Mu Feng saw Ling Shuang'er's appearance as a local tyrant, and he had to shake his head helplessly, people are more angry than people!

The young man in red shook his head and said, "It's still a little worse, if you can add a Xuan-level lower-grade spirit treasure, it will be sold!"

Mu Feng was also a little annoyed when he saw the young man in red sitting on the ground, a piece of gold-fetal ice stone, although rare, was definitely not worth two Xuan-level spirit treasures.

However, before Mu Feng could speak, Ling Shuang'er threw out a dagger with a spirit treasure under the Xuan Rank, and said, "Is this enough?" (To be continued......)
