Cheng Fei washed himself and changed into new clothes, Mai Xizhen helped him tie up his hair, and Cheng Fei no longer had to cover his short hair.

Cheng Fei's lotus pond has prepared a lot of daily necessities, even a knife to shave, and wants Mai Xizhen to help him shave his beard. Unexpectedly, Mai Xizhen shaved his skin as soon as he got started, and then he had to leave some stubble, which was much better than a sloppy beard anyway.

Mai Xizhen happily told Cheng Fei about the recipe for refining the nine-turn medicine furnace he had just seen, if this medicine furnace is used to process Dan, paste, pills, and powder, it can not only save 20% of the raw materials, but also shorten the time by 30%, but increase the finished product by 40%!

Yuan Kuang instantly extinguished the small flame of Mai Xizhen's excitement, saying that the recipe could not be spread, and even if it could be spread, it would not let her master any martial arts and refining methods here, because it was only for Cheng Fei's face that she survived.

Cheng Fei didn't think Yuan Kuang was joking, but he couldn't bear to look at Mai Xizhen's sullen appearance, so he had to ease the atmosphere, saying that Mai Xizhen didn't have anything to earn, at least she didn't have to pay back the life she owed.

Mai Xizhen's expression had just eased a little, and with a move of Yuan Kuang's hand, the blood gravel that Mai Xizhen had hidden in his arms flew into Yuan Kuang's hand, almost making Mai Xizhen burst into tears.

Cheng Fei couldn't help but blame Yuan Kuang for being too stingy.

Mai Xizhen was worried that Cheng Fei and Yuan Kuang would have a conflict, so she hurriedly persuaded Cheng Fei what he wanted to say.

Yuan Kuang didn't take it to heart, saying that Cheng Fei was a special case, others would not get any benefits from him, and it would be good to be able to save a small life. But they won't be grateful for Cheng Fei's kindness, because they won't remember what happened here.

Cheng Fei asked Mai Xizhen if she really wanted the blood, Mai Xizhen nodded again and again, but she immediately realized Cheng Fei's intentions, grabbed Cheng Fei's hand and shook her head.

Cheng Fei smiled slightly, but without any scruples, he reached out to Yuan Kuang to ask for those pieces of blood, the reason was to thank Mai Xizhen for helping him comb his hair and shave his face.

Yuan Kuang laughed angrily at Cheng Fei, raised his hand and threw the blood gravel to Cheng Fei, but asked Cheng Fei not to hand it over to Mai Xizhen in front of him.

Of course, Mai Xizhen will not be in a hurry, and she will lose the memory of this period of time, maybe she will throw away such an ugly little stone casually, it is better to hand it over to Cheng Fei for safekeeping.

As soon as Cheng Fei received the blood gravel on the lotus pond, he let out a short "ah" sound.

He didn't expect that drop of demonic blood to directly absorb the essence of one of the pieces of blood gravel, and watched that piece of blood and gravel explode into a dark red dust mist.

Cheng Fei scattered the dust mist in front of him, blaming Yuan Kuang for not communicating well with the demon blood, would he dare to put something on the lotus pond in the future?

Yuan Kuang hurriedly communicated with the demon blood, and explained to Cheng Fei that it was only because the demon blood had absorbed the essence of the blood gravel in the Spirit Treasure Hall that this misunderstanding occurred, in fact, the demon blood was nourished by the abundant and pure Xuan Qi provided by the lotus pond, and the things that Cheng Fei placed in the future would never have this kind of thing happen.

Cheng Fei asked Yuan Kuang for a recipe similar to refining the Nine Turns Medicine Furnace, which was regarded as a loss for Mai Xizhen's blood.

Yuan Kuang laughed and scolded Cheng Fei for being a scoundrel, but he didn't hesitate to turn around and look for the trick.

It's a pity that he couldn't find anything similar after looking around, and finally threw a jade slip for refining the Three Treasure Medicine Furnace to Cheng Fei.

He told Cheng Fei that the Three Treasures Medicine Furnace was a simplified version of the Nine Transformation Medicine Furnace, and therefore it was downgraded to an emperor-level spiritual treasure. But for Mai Xizhen, it is not bad to be able to refine an emperor-level medicine furnace, and the refining medicine furnace is definitely a luxury item in the sect.

The emperor-level nine-turn medicine furnace must be difficult for Mai Xizhen to refine, even if she asks her master to help refine it, she may not be able to control it. Even if that recipe could be passed on, it would be far less applicable than the recipe of this Three Treasure Medicine Furnace.

Mai Xizhen took the jade slip and looked at it, saving raw materials, shortening time, and increasing the proportion of finished products are basically the same as those of the Nine Turns Medicine Furnace, but it can only be used to process paste, pills, and powder, and the effect of alchemy is not good. It just so happened that the pharmacy hall where Mai Xizhen was located was not responsible for alchemy, so it didn't matter if it lacked the function of alchemy.

Yuan Kuang asked Cheng Fei if he still needed the refining method of the Dan Furnace.

Cheng Fei knew that he was sticking to his own principles, and he didn't want to give the magic trick directly to anyone other than himself, so he would make this extra move to make himself a mouthpiece.

Before he could ask, Mai Xizhen, who accepted it when she saw it, said that she didn't need it, and handed over the jade slip to Cheng Fei for safekeeping.

Yuan Kuang simply did a good job to the end, and sent twenty raw materials for refining the Three Treasures Medicine Furnace from the Treasure Cave to Cheng Fei together, and spoiled Mai Xizhen.

Cheng Fei didn't know the value of these medicine furnaces, how could she not know? Refining one was worth hundreds of thousands of taels of silver, which was the material for refining twenty medicine furnaces! Oh my God! How much did this cost! I couldn't count it on my fingers!

But Yuan Kuang extinguished the small flame of Mai Xizhen's excitement again, with her current strength, these twenty raw materials can successfully refine up to five medicine furnaces, and the other raw materials are for her to practice!

Mentioning the Treasure Cave, Cheng Fei thought of Elder Rao and the three of them.

Yuan Kuang said that they were fine, the two disciples had healing medicine on their bodies, but Elder Rao had no medicine but could use his skills to heal his injuries, and their injuries had basically recovered. With their cultivation, they won't be able to starve for another month.

Cheng Fei and Mai Xizhen felt that they should leave, and Yuan Kuang and Cheng Fei agreed on the details of contacting the descendants of the lineage.

Yuan Kuang has been over for so many years, and he is not in a hurry, anyway, his residual thoughts can last for a hundred years. The treasure here can't be cheapened in vain, and it must be investigated in many ways, and it must be handed over to the descendants who not only have the ability to carry forward the mountain barbarians, but also have the ability to make the history of Yuan Kuangqing flow.

Cheng Fei added that if other races, especially the human race, are too violent, no matter how outstanding their abilities are, they will not be considered.

Yuan Kuang hesitated slightly.

Not to mention that the temperament of the mountain barbarians is to believe that the big fist is everything, since the war between the gods and demons, the mountain barbarian clan is full of resentment towards the demons and the human race, even if they don't make things public, the fierceness and violence behind the scenes are indispensable, otherwise they may be looked down upon by the same clan, but I am afraid that they will not stop all these years. If this restriction is added, will there still be capable descendants?

Cheng Fei's attitude was very resolute, the good things here were worthy of the accumulation of hundreds of Yaohua Sects, and the sum of the three hundred and eight sects of the three hundred and eight sects of the Nine Great Sects of the Donghua Kingdom was less than one-tenth of this!

Yuan Kuang felt that what Cheng Fei said was reasonable, and no longer dwelled on this issue.

Cheng Fei asked him to be idle and sift through all the good things, and those that could not be circulated were either remodeled or buried deeply, so as not to cause a steady stream of trouble to his children and grandchildren, and even cause a bloody storm.
