Every cause must bear fruit, your catastrophe is me

Among all the people present, there are only a handful of people who can produce martial arts of the third and fourth grades, not to mention that even if they can afford it, they have to consider this person's background.

As one of the three major casting masters in Qingyu Holy Land, this person has a distinguished status and has a close connection with the Holy Land.

But those who are familiar with him know that this guy has a very small mind and always seeks revenge. Judging by his confident face, it seems that he is bound to get this demon core.

If anyone dares to bid in front of him, I am afraid that it will not be so easy to mess around in Qingyu Holy Land in the future.

After the fat man finished bidding, the scene suddenly became extremely quiet, and even the middle-aged man in room No. 11 gave up bidding after a moment of hesitation.

It is obviously not cost-effective to offend a master metalsmith for an earth fairy-level demon core.

"Is there anyone else who offers a higher price?"

Gu Long was quite satisfied with the value of the three fourth-grade martial arts, he asked the other people present with a smile.

No one answered.

However, Gu Long was not in a hurry, but waited with peace of mind.

After a while, there was still no reply, so he raised the small hammer in his hand high, and was about to drop it.

But at this moment, a deep voice suddenly came from Room No. [-], causing his arm to freeze in mid-air.

"A fifth-grade martial skill!"

click...

At this moment, no matter how good Gu Long's heart is, his body couldn't help but tremble a bit, because it was so shocking that even the hammer in his hand was crushed by the huge force of that palm.

"Fifth...fifth rank martial skill?"

Gu Long thought he heard it wrong, so he stood there and repeated in a low voice.

"That's right, a fifth-grade martial skill, in exchange for this demon core."

It was naturally Tang Yin who spoke, and he was standing behind the door shouting the price with his throat squeezed.

But when he said these words, he actually felt a little distressed in his heart. You must know that this is a fifth-grade martial art, no matter how rich you are, you may not be able to buy it.

Martial skills of this level can no longer be measured simply by money, even the strongest of Lve Shadow Sword Sect is only at the fourth rank.

It's also a loss that Hu Jiujiu had to spend such a large price to exchange for a demon core. If it was the exchange, he would definitely not hand it over if he was killed.

Although human martial arts are useless to him at all.

"Are you really willing to exchange fifth-grade martial skills?"

Gu Long asked in disbelief.

The value of the fifth-grade martial arts is definitely far beyond this monster core. Even though the monster core is owned by an earth fairy-level monster, unless you are a high-level alchemist or a casting master, otherwise it will be useless even if you have it in your hand .

Martial arts are different, as long as your cultivation base has reached alchemy, you can practice, not to mention fifth-rank martial arts, whose power is far from comparable to fourth-rank.

"That's right, rank five martial arts, do you want to change them?"

Tang Yin lowered his voice so low that most people would not be able to tell his exact age.

But at this moment, everyone present, including the Fatty Caster, all turned into a shocked expression, guessing the identity of the owner behind the door one after another.

Martial skills of this level are the treasure of the sect even in Qingyu Holy Land, how would this person be willing to exchange them for a demon core?
It is hard to imagine who is behind the door.

Because they couldn't sense Tang Yin's aura, some people who were originally in other VIP rooms on the second floor quietly came to Tang Yin's door and planned to check through the crack of the door.

But the strange thing is that when they arrived at the door, they found that the whole room was enveloped by an extremely powerful aura.

At the same time, as soon as the front foot stepped into this area, the body immediately became extremely heavy as if being suppressed by the mountains, and instantly made those who wanted to play tricks exit the door of the No. [-] VIP Hall.

Naturally, it was Hu Jiujiu who arranged the coercion of the aura. As an immortal, even if there was a demonic aura in his body, these Nascent Soul-level humans could not detect it.

Even if there are Mahayana powerhouses lurking in the auction house, they can't find their existence, and even Xiaoxiao's aura is well hidden.

After hearing Tang Yin's seemingly impatient words, Gu Long nodded repeatedly.

"Change, change!"

It seemed that he was afraid that this person would go back on his word.

Who would have thought that an earth fairy demon core could be exchanged for a fifth-grade martial skill for the Holy Land, and if the Holy Master finds out about this, there will be a heavy reward.

After the last lot was finished, the scene became noisy again.

But most of the people were not in a hurry to leave, but kept watching the stairs and the door of Room No. [-], wanting to see the identity of the people in that room.

However, it is a pity that this person seems to have had trouble with them. The auction house also discovered this problem at this time, so they began to send some guards to forcefully drive out the crowd.

This is also to protect the privacy of customers.

In an instant, there were only a few people left in the originally bustling auction room. Tang Yin, Xiaoxiao and Hu Jiujiu were sitting here drinking tea quietly.

After an unknown amount of time, a girl's voice came from behind the door.

"Guest, all the people in the auction house have left, you can go to the backstage to conduct transactions."

"okay, I get it."

Tang Yin did not continue to hide his voice this time. After answering, he looked at the two girls beside him, and finally his eyes fell on Hu Jiujiu.

"Xiaoxiao and I are ready to go out, what are your plans?"

"Well, you have to get the demon core for me first."

Hu Jiujiu showed him a charming smile, then stood up and stretched lazily, outlining the astonishing lines.

"Let's go."

As he spoke, he waved at the two of them, but when he was about to open the door, Tang Yin stopped him.

"Wait, are you planning to go out like this?"

"if not?"

Hu Jiujiu asked doubtfully with his back turned.

Before Tang Yin could speak, Xiaoxiao came to her side and said softly: "You were born with different pupils, won't you be recognized immediately when you go out like this?"

"Different pupils? You mean this?"

Hearing this, Hu Jiujiu pursed her lips into a smile, turned around the next second, and her original blue-green pupils suddenly began to change.

In a few seconds, the pupils of the eyes turned black like normal human beings.

At this time, she really looks like a normal human being, without a trace of evil spirit, popularity, or aura, just like an ordinary person who cannot cultivate.

It's just that the appearance is a little too coquettish, although she looks young, her frown and smile are as captivating as they are.

Really a goblin.

Compared with her, even Xiaoxiao looks so ordinary, I am afraid that only Gu Nanzhu can compete with her if she dresses up well.

Of course, it doesn't mean that Xiaoxiao is inferior to her, but that this girl gives people the impression that she is the girl next door, youthful and agile.

But Hu Jiujiu is naturally charming, exuding alluring charm all over her body. If she hadn't been very good-natured, no man would be able to restrain his desire in front of her.

It's no wonder that there is the word vixen, it can't be better applied to her.
