"What, is this scroll very good?" Du Qian said lightly as she looked at Du Fei, who was holding the scroll in a daze.

"Hehe, I just think that this blank thing is not placed here for no reason, maybe there is some secret in it. Du Fei said casually.

"Anyone can see this thing, what secrets can it have?" Du Qian smiled, and then her face turned slightly straight, "Okay, let's not talk about anything else...... Whether it is exercises or martial arts, we people of the Du family can only choose one of them, and even if we come in next time, there is only one thing that can be read, so Du Fei, you should choose it yourself. ”

"And this rule?" Du Fei was stunned, but it was a little strange.

"If there is no such rule, wouldn't it be possible to copy all the old foundations of the Du family if an outsider is mixed in?" Du Qian said lightly, "But you don't have to worry about this, after choosing, you can't look at anything else, in short, you can choose your favorite." However, my personal suggestion is to choose a seven-rank martial art, after all, these nine-rank exercises are really not enough. ”

Hearing this, Du Fei nodded quite understandingly, this thousand-year-old family, if there is no special protection for the martial arts in the family, as long as a traitor appears, wouldn't the entire family be copied.

It is estimated that his father left because of this relationship, otherwise, this place would have been emptied a long time ago.

His gaze slowly swept over the surrounding jade boxes, and finally landed on the jade boxes that emitted a cold light at the edge.

"Eight-rank martial arts, ice blade legs!"

This martial art can be said to be the only eight-rank martial art in the third layer, the reason why it can be put here, Du Fei is clear, that is, this ice blade leg is not very powerful in normal times, but if it is combined with the Du family's ice heart decision, then the power it exerts is not even worse than some seventh-grade martial arts!

It's just that there is no one in the Du family who can cultivate the Ice Heart Decision over the years, and naturally no one can do this Ice Blade Leg.

After hesitating for a moment, Du Fei still walked over, opened the box, and slowly opened the scroll under Du Qian's strange sight.

As soon as the scroll opened, the cold air hit the face.

"Xiaobai, enter the data into the system!"

Squinting slightly, Du Fei calmly ordered.

"The order is accepted, the system starts to enter the information, the entry is completed, whether to read-"

"Not for now. Du Fei replied in his mind, but he had already quickly stuffed the scroll back into the box, and casually pulled it on the other box a few times.

It's also strange to say, this box should have been easy to open, but I don't know why, no matter how hard you try, it can't be opened.

"It's really a bit of a doorway!" Praise in his heart, Du Fei's eyes fell on Du Qian's body, smiled, and said, "In addition to these, is there anything else to see?"

"What else do you want?" Du Qian rolled her eyes slightly, "You choose this fighting skill, and I won't say anything, this is your personal hobby...... At the same time, I also give you a suggestion, since you have chosen the fighting technique, that is, there is no way to get the exercises from the family, so there are only two options for you to choose next, the first is to go to the auction house to try your luck, and the second is to worship some sects...... If not, you don't have exercises to cultivate, then no matter how talented you are now, you will only be like that in the future!"

"Thank you for the advice. Du Fei smiled slightly, "I will naturally go to the auction house when I find a time, thank you Sister Du Qian for your advice!"

"To be honest, did you get the mantra of Bing Xin Decision from your father?" Suddenly with a strange smile, Du Qing took a few steps closer and said lightly.

"Of course not, you know, I was a waste before!"

"There is no best, and if there is, you have to be careful...... Bing Xindu, this Du family is a lot of people thinking about it......." After saying a rather inexplicable sentence, Du Qian smiled faintly, her figure flashed slightly, but she had already walked out of the door first.

...........

"Whew-"

With a long breath, feeling the feeling of true breath slowly swimming in his body, Du Fei exhaled and let out a rather comfortable ** sound.

I have to say that compared with the seventh level of forging the body and before the seventh level, both the power of the forging body fist and the feeling of cultivation are completely different.

Now every time Du Fei cultivates, he can clearly feel that the true breath in his body continues to flow and grow with his forging fist.

It's just that what makes Du Fei quite depressed is that the medicinal liquid that had a miraculous effect on his cultivation before has basically lost its effect now, even if he gritted his teeth and took all the medicinal liquids in one go, its effect was not great. According to Du Fei's calculations, it seems that it will take time for him to reach the eighth level of forging body!

"If you can refine the real Pulp Cleansing Pill instead of this half-finished ordinary medicinal liquid, I think there will be a lot of benefits. ”

Muttering to himself for a while, Du Fei also shook his head helplessly and sighed, he knew that before he really became a martial artist, he wanted to refine the finished elixir, which was basically a fool's dream!

"However, if you can't refine it yourself, it's a good choice to buy some!"

This thought flashed through Du Fei's heart, but it made him feel a little like seeing the moon through the clouds.

However, the value of this kind of thing is extremely high, and the place where it appears is generally an auction occasion, if you want to get it, it is estimated that it will not be possible to do it without tens of thousands of gold coins.

Although Du Fei's status in the Du family is different now, he doesn't think that it will be a good thing for him to go to Du Fei openly to get a sum of money to buy the myelin cleansing pill.

After thinking about it for a while, Du Fei came up with a pretty good idea.

The myelin-washing pill can be auctioned, and the myelin-washing liquid seems to be okay!

............

Three days later, Du Fei walked out of the inner room again, squinting at the sun, and had a feeling of being reincarnated.

In the past three days, he groped for refining the marrow washing liquid again, although he had the assistance of the system, but this time he still failed several times, and in the end, he was quite anxious to refine the thing.

At this point, Du Fei had to admit that this alchemy is really not something that ordinary people can carry out, and with the assistance of the system, he can carry out quite sophisticated alchemy is the result of this, and other people's alchemy doesn't know how hard it is.

It's just that if it weren't for the difficulty of alchemy, how could things like pills be so valuable?

After reaching out and groping for a few crystal bottles in his arms for a while, Du Fei smiled, left the Du family quickly from a hidden corner, and immediately walked towards a rather large auction hall in Buyue City.

The auction hall of Buyue, let alone in the city of Buyue, even in the southern part of the entire Da'an Dynasty has a lot of fame, because the items that can be put up for auction in the auction hall are undoubtedly quite rare.

And it is these things that can attract a lot of people to the auction house.

After standing at the door of the auction hall and squinting for a while, Du Fei walked into the corner of the alley and found a hat to hide his face. What's more, in such a large-scale auction hall like this, someone from the Du family must participate, and he doesn't want to be recognized.

After confirming that no one could easily see his identity, Du Fei slowly walked towards the gate of the auction hall, and in the wary eyes of the guards on both sides of the gate, Du Fei did not walk straight towards the lobby of the auction hall, but walked towards the small door on the side.

Seeing this scene, the guards breathed a sigh of relief, after all, most of the people who came here to sell things would have similar costumes.

After entering the small door, a rather spacious small hall appeared in front of Du Fei, there were several windows behind the small hall, each window had a black cloth hanging down, which could only be vaguely seen, and there was a figure behind it.

Du Fei knew that behind these windows were the appraisers in this auction house, and only these appraisers with a keen eye could see the value of a thing.

Sitting down at a window casually, Du Fei fumbled in his arms for a moment before placing the five crystal bottles in front of him.

"Huh-"

The man sitting behind the window seemed slightly surprised for a moment, and then opened one of the bottles, seemed to put it in front of him and sniffed it, and then hesitated slightly: "This is ...... Elixir!?"

"It's not an elixir, it's just that this thing is also a product of alchemy, I call it a marrow washing liquid, taking it under the seventh weight of the forging body, it has a miraculous effect, especially for people who are stuck in the sixth weight of the forging body, but can't take the marrow washing pill, take this thing, maybe they will have a chance to advance to the seventh level!" Hearing this, Du Fei explained casually.

"Really, and this thing, why haven't I heard of it......" The person at the window was shocked by Du Fei's explanation for a while, and then hesitated.

Because if this thing that Du Fei said was true, then its value was more precious than anything for those who could not advance to the seventh level of forging body.

Sighing helplessly, Du Fei said lightly: "It's true or not, can't you see it?" Even if you can't see it, just try it yourself......

"This ......" hesitated for a moment, and then the person behind the window bowed down and said, "My lord, is it Master Dan...... If yes......"

"Do you still need to reveal your identity when selling things?" Du Fei said coldly.

As if he heard the impatience in Du Fei's tone, the man hurriedly said respectfully: "This adult, I'm really sorry, but I really can't identify this thing, I don't know if the adult can wait for a while, I'll let the Yuan master of the auction house come to appraise it." ”

"Whatever!" Du Fei snorted and said lightly.

"Then, please go to the VIP room to rest for a while!" After finishing speaking, two maids had already walked out from behind the window respectfully, and immediately respectfully invited Du Fei to the side of the passage.

Du Fei skimmed and didn't say anything, but walked in with the maid and sat down casually.

After sitting in the VIP room for a while, I heard a burst of laughter from the door, and then a gorgeously dressed middle-aged man strode in.

After the middle-aged man walked into the room, he just nodded slightly at Du Fei, walked a few steps in a hurry, and then picked up the crystal bottle on the table, opened the bottle, and immediately poured out a drop from it and threw it into his mouth.

In just an instant, the middle-aged man was shocked, and immediately a respectful look appeared on his face.
