The instantaneous riot of the true qi in his body made Du Fei's face change drastically, and at this moment, he seemed to have lost control of the true qi in his body, and he could only watch everything happen.

It's just that this riot seems to be just a momentary thing, and before Du Fei can react, everything seems to be over.

And when Du Fei looked inward again, he was quite surprised to find that there seemed to be a subtle connection between the Condensing Pill in his dantian and his true qi, although he couldn't say why, but Du Fei could clearly feel that as long as he was willing, the medicinal power in this Condensing Pill could be borrowed by himself in an instant, and relying on the powerful medicinal power in the Condensing Pill, he estimated that he could have the strength of an eight-rank peak martial artist in an instant!

With such strength, although it is not against the sky, self-protection is more than enough.

Slowly exhaling, Du Fei also relaxed a little, although he didn't understand why this situation happened, he was not ready to investigate it at the moment, but opened his eyes slightly.

The moment he opened his eyes, Du Fei's eyes instantly turned into a basket of red, and the mysterious energy body seemed to flash in his eyes, and after a while, it returned to its normal blackness.

After taking the cultivation posture, Du Fei patted his right hand lightly on the ground, and his figure had already stood up. He squinted his eyes and glanced up at the night sky before chuckling softly.

Du Fei was extremely satisfied with the results of his cultivation this time, with the mixed pill method as his hole card, he also had the power of self-preservation during the trip to the Danwang ruins a month later, and what he had to do now seemed to be to try to see if he could refine the pill in large quantities.

Thinking of this section, Du Fei also sighed, this alchemy is not easy, and it is probably not easy to find medicinal materials.

Although Du Fei's identity in the Du family is different at the moment, he is not prepared to let Du Fei look for alchemy, after all, at this moment, the Du family, I'm afraid there are not many people on his side, if something happens, it is not what he thinks.

After thinking about it for a while, Du Fei still put his mind outside the Du family, as long as he could successfully refine a large number of marrow cleansing pills in secret, then it should be of infinite benefit to himself, right?

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

Early the next morning, Du Fei sneaked out of Du's house. It's just that compared with before, when the Du family met Du Fei, they were all a little respectful, which made his behavior quite eye-catching.

For this, Du Fei could only shake his head and smile bitterly.

After leaving the Du family quickly, Du Fei hesitated for a moment, but still found a dark corner, changed into a black robe for himself, including his face was also very well concealed, and after doing all this, he slowly walked towards the auction house.

The crowd at the auction hall is not at its peak at the moment, but it still looks extremely luxurious.

The guards at the door seemed to be quite wary of Du Fei's dress, but after a while, as if they had thought of something, those maids had already invited Du Fei to an accord with a respectful face.

Sitting in the Accord, gently swallowing the tea served by the beautiful maid, Du Fei did not make the slightest deliberate move, just waited silently.

As he expected, less than a moment later, Yuan Hong, the steward of the auction hall, had already appeared in the Accord with a smile.

"Hehe, this lord, I don't know what else is there to help you today?" Yuan Hong arched his hand slightly, and was already sitting on the side with a respectful face.

"Hmm," Du Fei just nodded casually at Yuan Hong's eagerness, and then he thought for a moment before he wiped a slight touch on the Rong ring in his hand, and then a jade box appeared on the table, "I've been a little tight recently, you can help me get this medicinal herb, in addition, you can prepare ten copies of these medicinal materials for me." ”

As he spoke, Du Fei casually threw out a roll of parchment.

Hearing this, Yuan Hong's eyes seemed to light up slightly, and after a while, he slowly opened the jade box on the table, and then his face changed slightly: "Lei Guangcao!?"

What appeared on the table was the medicinal materials that Du Fei snatched from the mouth of the Ben Thunder Mink that day, but although Du Fei knew that this thing was precious, he didn't know what this thing was.

It's just that as soon as Yuan Hong said this name, Du Fei's heart was already slightly shocked, and after a while, he muttered to himself: "Is it that kind of thunder light grass?"

"Beep-"

"The question is accepted, and in the system search, the owner asks whether it is a six-grade medicinal material, thunder light grass, thunder light grass, which is a thing formed by the condensation of thunderstorm energy in the sky on the day of the thunderstorm, and it is said that it is necessary to refine some six-grade and even five-grade elixirs, this thing is extremely rare, the formation conditions are special, and the value is extremely high......."

"Uh-"

Du Fei was slightly stunned, and a strange feeling rose in his heart about Xiaobai's first initiative to speak, but he thought for a moment and didn't understand why.

It's just that the unreliable system seems to have evolved unconsciously?

Of course, these are just Du Fei's speculations, but fortunately, in terms of the current situation, the system is only good for himself, and at the moment, Du Fei is no longer too worried, but his inexplicable eyes still fall on Yuan Hong.

It seemed to feel Du Fei's eyes, but Yuan Hong still cautiously appraised it, and then glanced at Du Fei with a little apprehension, and said in a deep voice: "My lord, do you really want to hand over this Thunder Light Grass to our auction house for disposal? You know, this kind of thing is extremely valuable, even if it is handed over to us for processing, I am afraid that it will not be able to be auctioned off smoothly for a while...... If you want a good price, I'm afraid you'll have to send it to the imperial capital......"

"Oh?" Du Fei chuckled lightly, "I don't think this thing is so precious, but since you say so, you can estimate a price......, right?"

"This ......" Yuan Hong hesitated for a moment, then his eyes swept over the parchment scroll on the table, and after a while, he gritted his teeth slightly and said, "My lord, if someone needs such a thing, the price is naturally extremely high, but if no one wants it, the price will be average...... So, I'm not going to make a good offer...... It's better to do this, the medicinal materials that the adults need, I will prepare them for the adults first, as for this thing, if the adults can trust it, I will arrange to send it to the imperial capital for auction, as long as there is a result, the adults can come to me at any time to receive the honorarium, I don't know if this arrangement is good?"

Hearing this, Du Fei frowned slightly, he didn't expect that this medicinal herb would allow this Yuan Hong to be treated so carefully, but what he cared more about was that he could get the medicinal materials for refining the myelin cleansing pill, and after thinking about it for a while, he nodded slowly.

Yuan Hong on the side, seeing Du Fei nodding, seemed to be a little relieved, and then he quickly called people and asked them to prepare medicinal materials, and then sat down on Du Fei's side with a little caution, smiled, and said, "This adult, I don't know what the relationship between Du Fei of the Du family and you is?"

"What do you mean?" Du Fei glanced up at Yuan Hong.

It seemed to feel that Du Fei was not angry, and Yuan Hong hesitated for a moment before he was slightly nervous: "Recently, in the city of Buyue, the most popular one should be this Du Fei." And the most mysterious thing about this Du Fei is that his identity as a Danshi is ...... Although everyone in the city is guessing, no one knows who he is taught so far, so I am guessing below, my lord, will it be his master?"

Hearing this, Du Fei's heart was also quite a little crying and laughing for a while, but after thinking for a while, he understood that this moment seemed to be an excellent opportunity.

After reaching out and knocking on the tabletop, Du Fei nodded lightly, and said lightly in a suppressed voice: "Yes, you are very smart, he is indeed my disciple." ”

"Is that really the case?" Yuan Hong looked cautious, "That young master Du Fei is such a talented character, and only a character like an adult can be cultivated!"

"Well, that's just his own talent, and it doesn't have much to do with me......" Du Fei nodded as if he didn't care, and continued after a while, "Since you know this, the proceeds of the Thunder Light Grass auction in the future will be sent to him, I may not have time to come to you." ”

"Yes! Yes!" Yuan Hong nodded again and again, "Since he is a disciple of an adult, then Young Master Du Fei is naturally also a guest of honor in our auction hall!

"Oh?" Du Fei glanced at him with a smile, and said lightly after a while, "You are very good at being a person, no wonder such an auction house has made you a good ......"

"Hehe, the adults praised it falsely, a little person like me only has this kind of ability. Yuan Hong nodded with a smile on his face.

However, after a while, someone had already sent the medicinal materials that Du Fei needed.

Yuan Hong hurriedly sent it to Du Fei in person.

After checking it casually and stuffing the medicinal materials into the Rong Ring, Du Fei nodded slowly and said, "Well, how much this cost, you can deduct it from the auction income of Lei Guangcao, if I still need it in the future, I will naturally come to you." ”

"We are waiting for good news from you. ”

"Okay, don't send it, I still have urgent things to do, so I'll leave first"

With a casual wave of his hand, Du Fei stood up and had already strode out of the auction hall.

Looking at the back of Du Fei leaving, Yuan Hong's face was also quite strange, his gaze slowly fell to the jade box on the table for a moment, and then he suddenly sighed and muttered in a low voice: "It seems that Du Fei really has a mysterious teacher, this Du family, there is one more Du Fei, and the backer is a little stronger...... It seems that the invitation of the Lian family has to be refused! even if you offend the Lian family, you can't offend a mysterious Dan Master!"
