"Diligent and studious, very good. ”

Du Feng's knowledge of the formation cannot, of course, be compared with the old gentleman in the bookstore. But he has some opinions of his own. As a result, the conversation turned into him learning from the old man, and it was free to study, and he even saved money by buying books.

But it doesn't matter, the old gentleman doesn't think that Du Feng is here to steal knowledge, but thinks that he is young and promising, diligent and studious. The more the two talked, the more speculative they became, and they forgot the time. If it weren't for the sudden noise outside, Du Feng wouldn't have reacted.

Oh no, he suddenly rang out, he came out to exchange for a medium-grade immortal stone for Xiao Hei to eat. Now that it is almost twelve o'clock, he has not brought back the medium-grade immortal stone, and it is estimated that Xiao Hei will be in a hurry.

"Senior, I have a reluctant request. ”

Du Feng was really embarrassed to say this, he didn't give money after taking someone else's jade Jane, and he hadn't bought anything yet, and now he still wanted to exchange low-grade immortal stones for medium-grade immortal stones from here. However, in order to get Xiao Hei promoted, he had to try it cheekily.

"If you're short of money, don't you, you can come to work with me. ”

Well, the old gentleman apparently misunderstood. Seeing Du Feng's embarrassed look, he thought that he had just come up from the Nether, so he was particularly short of money.

"No, no, I'm trying to ......"

Du Feng hurriedly explained that he didn't want to borrow money, nor did he want to work. Instead, I want to exchange some low-grade immortal stones for a few medium-grade immortal stones. Coincidentally, in the knowledge I just learned, I also have to use medium-grade immortal stones to help the elves recover.

"Affectionate and righteous, very good, very good!"

The old gentleman nodded when he heard this, and thought that Du Feng was trying to let Mu Ling reply as soon as possible, so he saved all the low-grade immortal stones he had worked so hard to save and exchanged them for medium-grade immortal stones. It's really rare to see such a loving and righteous young man.

Belch...... Du Feng was speechless for a while, really embarrassed. There are too many misunderstandings today, but I can't explain them. He couldn't take out a lot of phoenix diamonds and tell the old man that he actually had money. In that case, not only will you not be respected, but it will destroy the friendship between the two.

"Please also ask the seniors to do a lot of Haihan, I really have an urgent need. ”

Du Feng's anxious look was not pretending. He was indeed in a hurry to take the medium-grade immortal stone and go back to Xiao Hei to use. Because it was about to reach twelve o'clock, the Yuan Force attribute of the underground immortal vein should change as soon as twelve o'clock passed.

"Okay, okay, it's okay if you go. ”

The old gentleman looked at Du Feng more and more pleasing to the eye, and directly exchanged the medium-grade immortal stone for him. Although theoretically a hundred low-grade immortal stones can be exchanged for a medium-grade immortal stone. However, in the actual exchange process, no one is generally willing to exchange from high to low, so the price needs to be increased.

The old gentleman looked at Du Feng so pleasing to the eye, so naturally he didn't need to increase the price. Not only did he not need to increase the price, but he also gave Du Feng a healing pill, because his old man had already seen that Du Feng still had injuries that had not healed. Don't underestimate this healing pill, the effect of just one is stronger than Du Feng's bottle. Because what they sent was a second-order elixir.

"Thank you so much, thank you so much!"

Du Feng couldn't believe what kind of luck he had taken. In the past, when I went to a new place, I was found in all kinds of tribulations. But this time when he entered Quarter City, he first bought a temporary status quota from Chen Lei cheaply, and then escaped the detection of the City Lord's Mansion before nine o'clock in the evening. This time, he successfully exchanged for a medium-grade immortal stone, and also earned a second-order healing pill for nothing.

Because he was in a hurry, Du Feng hurriedly ran back after thanking him. Anyway, the old man's book house has existed for a long time, and it is not too late to thank him when he has the opportunity to finish this paragraph. So he didn't linger and soon returned to the rented house.

"Quick, hurry up and eat. ”

The first thing he did after entering the house was to give Xiao Hei all the medium-grade immortal stones he had exchanged.

"Hehe, I know that Brother Du will definitely be able to get it. ”

Seeing that it was almost twelve o'clock at noon, Xiao Hei was still full of confidence in Du Feng. Finally swallowed all the medium-grade immortal stones in one bite, and then I saw that the thick purple arc Zraz was sparkling all over its body.

"Alright, it's time for me to go back to sleep. ”

Hearing this, Du Feng sucked in the room, as long as Xiao Hei wants to sleep, then the next step must be promotion. My estimate is correct, the effect of eating low-grade fairy stones is too weak now, and it is a little too early to eat phoenix diamonds, and the effect of medium-grade fairy stones is just right.

Xiao Hei turned into a black light and drilled back into the small world of the necklace and began its whirring and sleeping business. Just after twelve o'clock, the attributes of the underground immortal veins began to transform towards the wind system. This was originally nothing, but Du Feng suddenly thought of the second-order healing pill given by the old man.

The healing pills that I usually eat are mainly hydrotherapy pills, and there can also be wood attribute medicinal powders. But the one that the old gentleman gave turned out to be a wind-attribute healing pill. He seemed to have calculated that Du Feng was going to take this wind therapy pill in the next time.

Because the wind attribute is too sharp and difficult to control, very few people use it to make healing pills. If you don't control it well, not only will you not be able to heal, but you may also hurt yourself. However, for the old gentleman's second-order healing pill, Du Feng still has confidence. He opened his mouth and ate it, and then began to heal with the help of the wind attribute yuan power of the underground immortal vein.

The Wind Therapy Pill is really different from the usual Spa Pill, and the medicinal properties are very violent. As soon as he entered his stomach, he began to scurry around, a whirlwind of medicinal power swirled rapidly in Du Feng's dantian, and there were many small whirlwinds that rolled directly towards the meridians of his body.

Ooh...... This kind of medicinal stimulation is really painful, if it weren't for Du Feng's understanding of medicinal properties, he might have thought that he was poisoned. Generally speaking, when using the Healing Pill, you will feel that the injuries all over your body will be reduced, and the pain will also be reduced.

However, this wind therapy pill is different, not only will it not reduce the pain, but it will also refer to strengthening. Du Feng, who was in pain, was sweating profusely, and some gray-black dirt oozed out of the sweat.

Yes, he was in a hurry before, and he had eaten so many inferior practice pills and healing pills, and the impurities had not been cleared. In particular, those impurities hidden in the cracks of the meridians will take a long time to metabolize if they accumulate in the body.

This time, because of the stimulation of the wind healing pill, all the cracks on the dantian and meridians were reopened, and Du Feng, who was in pain, died and lived. Then it closed hard, and it hurt him again. Along with the severe pain, those impurities are squeezed out. After the medicinal power disappeared, Du Feng's whole body was no longer painful.
