This person has a bit of coolness in his nature, and when he heard Yun Shan's words, he couldn't help but laugh and admire, and then continued:

"This red cloud crystal is precious and abnormal. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 infoWhen refining a treasure artifact, you only need to add a small amount each time to greatly improve the quality of the artifact. This fist-sized crystal, if it is brought to the auction building, can at least fetch the price of five hundred essence stones. But such treasures are priceless and will only be traded through barter. ”

"I see, thank you seniors for telling me." Hearing this, Yun Shan also had some understanding of the price and trading methods of this kind of rare ore, and bowed his hand to the stall owner, and wanted to turn away.

"Little brother stay!" Yun Shan was stopped by the stall owner, turned around, and looked puzzled.

The shopkeeper smiled slightly, "These ores in the middle of the stall are going to be exchanged for pills to improve my cultivation, which is extremely important to me." However, if the little brother has other things he needs, he can put them forward, and if he has them, I will give them to you, and you should have a good fate. ”

"Oh?" Yun Shan's eyes lit up, of course he would not refuse this kind of good thing, and said to the stall owner: "Then thank you to the seniors first, the juniors are now looking for the unilateral side of the Blood Essence Pill, I don't know if the seniors have it?" ”

"Hmmm... Although this kind of unilateral is rare, it is not a precious thing, but I don't have it in my hand, but if the little brother dares to be interested in alchemy, I have a few bottles of refined and condensed middle-level demon beast essence blood here, which is a necessary material for refining blood essence pills, and I also have some low-level demon pills saved in the early years, these are of little use to me, so I will give them to you as a practice. The stall owner groaned slightly, pointed to a few jade bottles on the ground, and took out a brown leather bag from the storage bag and threw it to Yunshan Dao at will.

Yun Shan was overjoyed, although these materials could be collected in the mountain by themselves, but if they wanted to get such a large amount, it would take a lot of time and energy.

"Then you're welcome!" He smiled, first put away the brown leather bag, and then put all the bottles and cans on the ground into the storage bag, and sighed at the stall owner's boldness and generosity.

Seeing that Yun Shan had put away his two jars of high-level demon beast essence blood, the stall owner twitched slightly unnaturally on his face, but he didn't say anything to stop it.

"Hehe, boy Yunshan, I don't know what this senior is called?" He took so many things from others for nothing, and he couldn't help but be a little embarrassed, although he knew that it was a little inappropriate to ask like this, but he was favored by others, and he should repay it in the future, but it would be difficult to do it if he didn't know the identity of the other party.

The stall owner seemed to see Yun Shan's thoughts, nodded at Yun Shan, waved his hand again, and said, "Well, the little brother has a heart, go ahead!" Go ahead! Then he returned to the way he had just closed his eyes.

Seeing that the other party didn't say his identity, Yun Shan saluted knowingly and turned to leave.

Yun Shan bumped into the great luck and obtained the alchemy materials, but the Dan Fang had not yet landed. Between the stalls, he shuttled, and after shopping for a long time, he didn't find the Danfang of the Blood Essence Pill, but he encountered a few herb-based Danfang, but he knew that he was shy in his pocket, and he was not interested in asking the price, so he went directly to the next stall to search.

Before I knew it, I had come to the end of the stall street, and there was no open space in front of me to set up a stall, but a simple and tall stone house.

The surface of a boulder on the door was delicately hollowed out, and the remaining protruding word "Judan" and the gray and black walls did not know how many years had passed. Although there are no cracks on the surface, it has been eroded and uneven, forming a layer of fine irregular lines.

"There is a word "Dan" on the door, presumably the business here should be related to pills. ”

Yun Shan had a glimmer of hope in his heart, and walked in quickly.

The interior of the shop is very spacious, and the surrounding walls are carved out of neat lattices, on which some jade bottles and jade slips are sparsely placed. In the center of the shop there are a few small round stone tables and a few stone benches, which seem to be for customers to relax.

On the edge of one of the stone tables, there was a middle-aged man drinking tea, who was looking bitter at this moment, I don't know if the bitterness of the tea was too heavy, or if he had something else on his mind.

"Huh?"

"Shopkeeper Xu?"

As Yun Shan walked into the door, the middle-aged man came back to his senses when he heard the sound of footsteps. When they saw the person clearly, they first let out a light "huh", and then the two of them exclaimed at the same time.

This middle-aged man is none other than Xu Jincai, the shopkeeper in the Juxian Building in Yuquan City.

"Hey, hey... It seems that the little brother has entered the threshold of cultivation, congratulations, congratulations! "At the beginning, Xu Jincai purchased a large number of demon beast materials from Yunshan, so he was exceptionally promoted to be the shopkeeper here. Although Yunshan has grown a lot taller, he was still recognized by Xu Jincai at a glance, and when he saw this lucky star entering the door, he was happy in his heart, and hurriedly stepped forward to greet him warmly.

"Tsk... It seems that Shopkeeper Xu has also made a lot of money from me! Rejoice, rejoice! When Yun Shan spoke, he didn't look at the shrewd guy in front of him, but his eyes fell on the surrounding walls, and he praised in his mouth.

After saying this, the two of them stood opposite each other with strange faces, looked at each other, and after a while, they couldn't hold back their laughter at the same time, and laughed out loud.

After laughing for a while, Xu Jin preached to Yunshan with an embarrassed face.

"Little brother is here this time to buy pills and improve his cultivation? If that's the case, I'm afraid I'm going to disappoint you. In recent years, the herbs of the previous year have become more and more scarce, so the elixir to improve the cultivation has been in short supply, and now my small shop has been out of stock for a long time. ”

"Is it so scarce? But I'm not here to buy the pill, do you have a blood essence pill for sale here? Yun Shan was slightly surprised when he heard this, and then asked with a twist of words.

Xu Jin was slightly stunned when he heard that Yunshan was going to pay the bill, but he immediately returned to his true character as a profiteer.

"Oh? The pill of the Blood Essence Pill? We do have this in our store. But ... ”

"This guy! It's started again ... Yun Shan saw Xu Jincai's appearance, and scolded in his heart. Then he said, "Say it! Is the sample not for sale originally? Or is it sold as a set? ”

"Hey, hey... The little brother is really an understanding person. This one... We do not sell a single type of Danfang separately. If the little brother wants to buy the Dan of the Blood Essence Pill, I recommend this "Demon Pill Nine Alchemy" to you, this "nine" character is just a virtual finger, and there are actually dozens of ways to refine the pill with the Demon Pill as the material, and the price is only five essence stones. Xu Jincai smiled, took out a jade slip from the lattice on one side of the wall, and handed it to Yunshan Dao.

Yun Shan heard that there were no less than dozens of Dan recipes, and he was pleasantly surprised, and stretched out his hand to take the jade slip, and before he could check it, Xu Jincai took out another jade slip from the grid next to him, and also handed it to Yun Shan and continued:

"This is a "Detailed Explanation of the Demon Pill", which details the characteristics of the Demon Pill of different types of demon beasts. For example, some fire-attribute demon pills are extremely violent and hot, and if they are not handled properly, they will explode. For another example, the outer wall of the demon pill of some scale armor demon beasts will be very strong, and it is difficult to refine the essence inside with ordinary refining methods, and it needs to be treated with some special methods before it can be refined, etc。。。。。。

The content of this is very helpful for refining the elixir made of demon pills. The price is also relatively cheap, with only two essence stones.

What do you think? Does the little brother want to buy both? ”

Yun Shan was happy in his heart, but he didn't show it on his face at all, and pretended to be displeased: "Hmph, don't you know when I am the shopkeeper?" The materials for refining jade slips can be purchased dozens of them with a single essence stone, and these jade slips can be copied infinitely, and you and I know how big the price difference is. So be it! I bought both of the four essence stones. ”

"I said little brother! If the boss finds out that I sell it so cheaply, I will definitely blame it! For the sake of our relationship in the past, I will privately pay you two essence stones. There are a total of five essence stones, you can take these two classics! Xu Jincai clenched his teeth and said with a painful look.

"Oops! Then thank you for your generosity. Yun Shan made a grateful look, put away the two jade slips, then took out five essence stones, and stuffed them to Xu Jincai with trembling hands, and at the same time held his hand excitedly, and did not let go for a long time。。。。。。

Golden Sword Gate, Zhuhai Peak.

In the stone house, Yun Shan sat on the stone **, slowly put down the jade slip he was holding from his forehead, and opened his eyes.

This Blood Essence Pill's Danfang Yunshan has been studied several times, and according to the above description, this refining method is also simple.

First put the demon pill into the Dan furnace, and then use the essence in the body to urge the Dan furnace to generate a furnace fire.

Then slowly refine the outer wall of the demon pill, calcine and purify the essence inside, and finally inject an appropriate amount of demon beast essence blood into the furnace, and at the same time control the furnace fire to slowly cool down so that the essence in the Dan furnace and the demon beast essence blood are fused, and gradually cooled and condensed into a pill.

Although the method is simple, if you want to become a Dan, it is extremely difficult. There are many places in it that require repeated exploration and trial by the refiner to succeed.

For example, the control of the fire is the biggest difficulty.

The heat is too small to dissolve the outer wall of the demon pill. If the fire is too fast, the demon pill is easy to explode. The heat is too weak to purify the essence. If the heat is too strong, it is easy to lose too much essence and lead to the loss of medicinal power.

The final condensation stage is even more accurate to grasp, and the slightest deviation will lead to the failure of condensation.

Another example is the influence of the demon pill attributes, the amount of demon beast essence blood injected, the size and quality of the Dan furnace, and so on。。。。。。

Now Yun Shan finally fully understood why the price of the pill was so expensive. Affected by so many factors of becoming a pill, even a skilled alchemist, the probability of becoming a pill is probably very low. This has caused a significant increase in the cost of the elixir, coupled with the massive material support required to train an alchemist, resulting in a very small number of alchemists. Naturally, there are few pills, and the price is not high.

"Hey。。。。。。"

He sighed.

Although before reading the Danfang, he had already been mentally prepared for the difficulty of alchemy. But after reading it, the original confidence was still inevitably hit by hatred.

Even though he was deeply hit, Yun Shan had no intention of giving up, and now he had a lot of materials available, so he had to at least try it himself.

。。。。。。

A light cloud of smoke rose as if trying to meet the clouds in the sky, but it slowly dissipated not far below the clouds

This light smoke drifts over the Golden Sword Gate all year round, regardless of spring, summer, autumn and winter. Beneath the light smoke is a half-shaped low peak, the summit of which is a patch of red, from which the light smoke emanates.

On the mountainside of the low peak, there is a stone hall that has been smoked black. Inside the stone hall, a young man with sturdy hands and feet was sitting cross-legged beside a smoky Dan furnace.
