Thank you for your concern, this cold did not have a fever, it was a cough and lack of strength, and I woke myself up in the middle of the night last night.

Yang Kai scratched his head, he thought that more than one hundred and fifty spars were already a good fortune, but when it was really time to use them, he found that these spars were still too few.

"Don't look at me, I don't have any hedrons. Shui Ling was helpless, she had lived in Zhongdu for more than two years, and the spars she originally carried had long been consumed.

Yun Xuan had been listening to the side, and only then did she grit her teeth and say, "I have a piece of empty cicada jade here." ”

Yang Kai looked at her in amazement.

"Anyway, it's useless for me to keep it, so I'll give it to you. As she spoke, Yun Xuan reached out and took out a piece of jade that was as white as a jade and the size of a fist from the Qiankun bag on her waist.

Yang Kai frowned, groaned, reached out and took it and said, "I'll borrow you." ”

"No, I don't. Yun Xuan smiled slightly.

Master Ma looked at Yang Kai, and then at Yun Xuan, a little unsure of what Yun girl looked very good to this young man, and even gave away such a valuable material as the empty cicada jade.

Is there any value for a teenager who came out of a remote corner to invest in? Master Ma was thoughtful.

Handing over the Empty Cicada Jade and the Ice Flame Star Sand to Master Ma, Master Ma took it and coughed lightly: "You are not a disciple of my Duao Alliance, it stands to reason that the cost of refining and repairing the secret treasure will be increased by two percent......"

Saying this, he looked at Yun Xuan and said with a slight smile: "But for Miss Yun's sake, this time the old man will accept a hundred spars from you." You've got this hedron all right, right?"

The young man was poor at first glance, and Master Ma didn't dare to ask for too much, so as not to make Yun Xuan lose face.

Yang Kai nodded, took out a hundred spars and handed them over.

Master Ma showed a satisfied expression and said, "Take it in ten days, and I will return you a brand new secret treasure at that time." Promise not to disappoint!"

"Then we'll quit first. Yun Xuan bowed slightly. led Yang Kai and Shui Ling back the same way.

Out of the Secret Treasure Hall, Yang Kai opened his mouth and asked, "How much is that piece of empty cicada jade worth?"

Yun Xuan smiled and said nothing, but Shui Ling quietly gestured at him.

Yang Kai's face darkened.

He didn't have many valuable things on his body that he could give to Yun Xuan as compensation, and he wasn't going to expose the elixir or something, and the Ice Flame Star Sand was all handed over to Master Ma, and he originally wanted to give some to Shui Ling. But now we have to give up.

Anyway, Shui Ling is the little princess of the Water Temple, and probably won't care about these gains and losses.

"I'll pay you back. Yang Kai reiterated that he didn't like to owe favors to everyone, especially people he didn't know well, and Yun Xuan's overtures were obviously because of Shui Ling.

A few cents and taels yourself. Yang is happy to know. Yun Xuan would not send such valuable materials in order to make friends with her.

"Don't say it, you man ......" Yun Xuan pursed her lips and smiled, shaking her head, "Okay, if it's okay, let's go back."

"I still want to buy something. Yang Kai said.

"Oh, what do you want to buy, I'll show you the way. Yun Xuan looked at him with interest.

"Buy some herbs. ”

"What are you buying medicinal herbs for?" Yun Xuan asked, and suddenly her beautiful eyes lit up: "You are an alchemist?"

Yang Kai shook his head: "It's just that I'm a little interested in alchemy." I want to look into it. ”

"Isn't it?" Shui Ling was also dumbfounded. The time she spent with Yang Kai was not short, but she had never seen him refine pills. She did know that Yang Kai had a very close relationship with Xia Ningsheng. Xia Ningshang has a deep attainment in alchemy, but a person who has never been in contact with alchemy actually said such a thing at this moment, Shui Ling is a little incomprehensible.

"It's just fun. Yang Kai smiled.

Anyway, there is nothing to do now, Master Ma also said that he can only go to retrieve the bone shield in ten days, Yang Kai naturally wants to use this time to do something serious.

And alchemy is something he has always wanted to do, but he has no time to do.

If you don't enter the iQue Realm, you can't refine the pill, this is the teaching of the Medicine King Gu Yunyin Peak Xiao Fusheng!Yang Kai has already been promoted to the iQue Realm, and he has also met this condition.

Yang Kai, the elixir used in his cultivation before, didn't need to worry about it, with the little senior sister here, any elixir could be refined. But now, he came to the Tongxuan Continent alone, and there was no news from them, so Yang Kai had to plan for his future.

It's better to have a skill than to have no strength.

"I don't understand you. Shui Ling shook his head.

"Then come with me, I'll take you to buy the medicinal herbs you need, what herbs do you want?"

"The lower the better!" Yang Kai said.

Yun Xuan was stunned: "The lower the better, you can't never refine Dan, right?"

Only some apprentices who are new to the path of alchemy will choose low-grade medicinal materials to practice.

"He hasn't practiced before!" Shui Ling smiled.

"You're really just having fun. Yun Xuan was happy, and he didn't mean to stop it, so he led Yang Kai and Shui Ling in one direction in the city.

The more you go, the more remote it becomes, the things you see along the road are getting lower and lower, and even the level of martial artists who come in and out of here is no longer as high-end as what you saw before.

Yang Kaizhi said, this should be the trading area for the low-level martial artists and low-level materials in Duao City.

After a short time, the group of three came to a pharmacy, which was full of all kinds of low-grade materials, and there were many alchemist apprentices and alchemist apprentices looking for materials to practice their hands.

The material is of low grade and cheap, but because of the large amount used, the business here is also relatively hot.

Under Yun Xuan's guidance, Yang Kai used fifty spars to buy a large number of low-grade medicinal materials and left satisfied.

Back at the Yunxuan team's mansion, Yang Kai closed the door, laid an enchantment outside the room, and began the path of alchemy in high spirits.

He knows the essence and mysteries of alchemy.

Over the years, the information he has continuously spied on from the true recipe of alchemy has made his knowledge of alchemy even richer than that of Xia Ningsheng.

The structure of various spirit arrays, the selection of medicinal materials, the mastery of fire, the experience of various alchemy masters, and so on, no one can match it.

What Yang Kai lacked was only practical experience.

Moreover, the attributes of his true element and divine consciousness. It is also quite suitable for alchemy.

Scorching True Yang Vitality. It is easier to condense the medicinal effects of medicinal materials.

It can be said that in terms of alchemy, Yang Kai has unique conditions that many people can't match, although it can't be compared with Xia Ningsheng's medicinal spirit holy body, but compared to other alchemists, the conditions are much better.

He poured out all the low-grade materials he had purchased in the black book space, and took out the small incense burner.

This incense burner is the treasure that appears when the third page of the Black Book is unsealed. But ever since he had spied on the mystery of the true recipe of alchemy, Yang Kai knew that it was more than just an ordinary incense burner.

It is also a Dan furnace that can be used for alchemy!

This incense burner and the alchemy recipe should coexist and complement each other, but I don't know what the alchemy recipe is, the alchemy recipe is hidden in the statue of the Dan saint in the Medicine King Valley, if it weren't for the accident. Yang Kai might have missed the secret of the true recipe of alchemy.

The original owner of the Black Book seemed to have deliberately prevented Yang Kai from embarking on the path of alchemy, and had no intention of conveying the true recipe of alchemy.

However, as it turned out, his plan fell through.

Reaching out and stroking the small incense burner, Yang Kai poured the true yuan inside, and according to a certain route, let the true yuan wander in the incense burner.

Soon, the incense burner flashed with lines-like light. With the advent of light. The small incense burner swelled up and became the size of a water tank.

Yang Kai withdrew. Nodding in satisfaction.

The size of the Dan furnace, to a certain extent, can intuitively reflect whether an alchemist's skills are exquisite.

The larger the Dan furnace needed, the worse the level of this alchemist, because during the alchemy, the alchemist needs to use the true yuan to engrave different spirit arrays in the Dan furnace, so that the spirit array can play a role, fuse and promote the medicinal effect, let the medicinal materials conflict in the Dan furnace, and finally condense the elixir.

And the skilled alchemists, no matter how small the Dan furnace is, can accurately carve out the spirit array, there will be no deviation, and they can also master the fire.

The Dan furnace the size of a water tank is suitable for Yang Kai to practice. With such a large Dan furnace, the fault tolerance rate is also slightly higher, and it doesn't matter if the true yuan is poured a little more.

Recalling the configuration of the pill, Yang Kai found the corresponding medicinal herb from the pile of low-grade materials, put it aside, and then kept punching out the seal with both hands, pouring the true yuan into the pill furnace.

Soon, a simple spirit array took shape in the Dan furnace.

Because he wanted to practice, Yang Kai chose a spirit array that increased the success rate of alchemy, and this spirit array was a basic spirit array, and it was not too complicated.

Yang Kai had the ability to control the formation and stability of this spirit array.

After inspecting the spirit array in the Xia Dan furnace, Yang Kai was extremely satisfied.

Put the selected low-grade materials into the Dan furnace in order, and pour in the true yuan as you put them in, and condense the medicinal effect with the scorching true yang vitality.

In this process, the valuable experience and experience that belonged to those alchemy masters in the alchemy true recipe surfaced in Yang Kai's mind little by little, allowing him to compare it with the situation in front of him.

These alchemy masters also used to know nothing about the way of alchemy, and they were blank about the mysteries of alchemy.

But through their own efforts and talents, they have reached the height of admiration step by step.

Yang Kai was careful in his control, because the amount of true yuan infusion was directly related to the condensation of the medicinal effect, and if he poured too much, he might incinerate the medicinal materials, and if he poured less, the medicinal effect would not be fully exerted, and he would not be able to become a pill.

Alchemy is an incomparably delicate work, and it has very strict requirements for the control of its own true element.

One by one, the herbs melted under the action of Yang Kai Zhenyuan, fused together, and a gratifying change occurred.

However, just when Yang Kai thought that this time he would almost succeed, a puff of black smoke suddenly came out of the Dan furnace, and the smell of burnt paste quickly filled the room.

Yang Kai stopped the infusion of True Yuan and frowned.

He knew that this alchemy had completely failed. There seems to be some problems with his true yuan infusion, and the strength used is a little greater, resulting in the incineration of all the medicinal materials.

Taking out the waste burned in the Dan furnace, Yang Kai did not rush to continue to do it, but calmed down and recalled what he had just felt, confirming it with the correct method. (To be continued.) )
