Thank you for your concern. I didn’t have a fever this time, I just coughed and had no strength. I woke myself up in the middle of the night last night.

Yang Kai scratched his head. He thought that more than 150 crystals were already a good fortune, but when he was really using them, he realized that there were still too few crystals.

"Don't look at me, I don't have crystals on my body." Shui Ling was helpless. She had lived in Zhongdu for more than two years, and the crystals she had originally carried had already been consumed.

Yun Xuan kept listening to her side, and only then gritted her teeth and said, "I have an empty cicada jade here."

Yang Kai looked at her in shock.

"It's not very useful for me to keep it anyway. I'll give it to you." As he said, Yun Xuan reached out to take out a piece of jade as white as jade and the size of a crystal-sized fist from the Qiankun bag on her waist.

Yang Kai frowned, pondered for a while, reached out and said, "I'll borrow it from you."

"No." Yun Xuan smiled slightly.

Master Ma looked at Yang Kai and Yun Xuan. He was a little confused about why Miss Yun looked very good to this young man. Even the materials such as Kong Chanyu were generously sent out.

Is the boy who came out of a remote corner worth investing in? Master Ma thoughtful.

He handed Kong Chanyu and Bingyan Xingsha to Master Ma. Master Ma took it and coughed lightly: "You are not a disciple of my Duao Alliance. Logically speaking, the cost of refining and repairing secret treasures will be increased by 20%..."

As he said this, he looked at Yun Xuan and smiled and said, "But for Miss Yun's sake, I will accept you a hundred crystals this time. You should have this crystal, right?"

This young man looked so poor that he was so poor that Master Ma didn't dare to ask for too much, so as not to let Yun Xuan lose face.

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

Master Ma showed a satisfied expression and said, "Let's get it ten days later. I will give you a brand new secret treasure at that time, and I will guarantee that you won't disappoint you!"

"Then let's take a break first." Yun Xuan nodded slightly and led Yang Kai and Shui Ling back the same way.

After leaving the Secret Treasure Hall, Yang Kai asked, "How much crystal is that piece of empty cicada jade worth?"

Yun Xuan smiled without saying a word, but Shui Ling quietly gestured to him.

Yang Kai's face turned dark.

There were not many valuable things on him that could be given to Yun Xuan as compensation. He was not going to expose the Ten Thousand Medicine Spirit Liquid, and the Ice Flame Star Sand was also handed over to Master Ma. He originally wanted to give some to Shui Ling, but now he had to give up.

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

"I will pay you back." Yang Kai reiterated that he didn't like to owe everyone favors, especially those who were unfamiliar. Yun Xuan's show of kindness in this way was obviously because of Shui Ling.

Yang Kaixin knew how much she was. Yun Xuan wouldn't give such expensive materials to make friends with her.

"Everyone said no, you man..." Yun Xuan smirked and shook 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 lead you the way." Yun Xuan looked at him with interest.

“Buy some medicinal materials.”

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

Yang Kai shook his head: "I'm just a little interested in alchemy, I want to study it."

"No?" Shui Ling was also stunned. She had been with Yang Kai for a long time, but she had never seen him refining elixirs. She knew that Yang Kai and Xia Ningshang had a very close relationship. Xia Ningshang had a deep attainment in alchemy, but a person who had never been involved in alchemy said such words at this moment. Shui Ling didn't understand it very much.

"Just just have fun." Yang Kai smiled.

Anyway, there is nothing to do now, Master Ma also said that he would not get the bone shield in ten days, so Yang Kai naturally wanted to use this time to do some serious business.

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

Not being involved in the Shenyou Realm or refining elixirs is the teaching of Xiao Fusheng from Yunyin Peak of Medicine King Valley! Yang Kai had already been promoted to the Shenyou Realm and met this condition.

Yang Kai used to practice the elixir used in the past. He could make any elixir with his junior sister. But now, he came to Tongxuan Continent alone, and there was no news from Manager Meng and others, so Yang Kai had to make plans for his future.

Having a skill is always much better than having no strengths.

"I can't understand you." Shui Ling shook her head.

"Then come with me, I'll take you to buy the medicinal materials you need. What medicinal materials do you want?"

"The lower the level, the better!" Yang Kai said seriously.

Yun Xuan was stunned: "The lower the better? You haven't never refined the pill, right?"

Only some apprentices who are just beginning to enter the alchemy method will choose lower-level medicinal materials to practice.

"He has never practiced!" Shui Ling smiled.

"You're really just having fun." Yun Xuan was happy, and had no intention of stopping her. She led Yang Kai and Shui Ling to the same direction in the city.

The more you walk, the more remote you are, the grade of things you see along the road is getting lower and lower, and even the level of warriors entering and leaving here is no longer as high-end as you have seen before.

Yang Kai knew that this should be a trading area for the lower-level warriors and underlying materials in Duaocheng.

Soon, the group of three came to a medicine shop, which was filled with various low-quality materials, and there were many alchemists and apprentices of weapon refiners looking for materials here for practice.

The materials are of low grade and cheap price, but because of the large amount, the business here is also quite popular.

Under Yun Xuan's guidance, Yang Kai used fifty crystal stones to buy a large number of low-quality medicinal herbs and left with satisfaction.

Back at Yunxuan's team's mansion, Yang Kai closed the door, set up a barrier outside the room, and began the road of alchemy with great enthusiasm.

He is well aware of the essence and mystery of alchemy.

Over the years, the information he has been constantly exploring from the true alchemy skills has made his knowledge of alchemy more abundant than Xia Ningshang.

The structural functions of various spiritual arrays, the selection of medicinal materials, the mastery of heat, the experiences and experiences of all alchemy masters, etc., no one can match them.

What Yang Kai lacks is just practical experience.

Moreover, his true essence and spiritual attributes are also quite suitable for alchemy.

The hot true yang energy makes it easier to condense the medicinal effects of medicinal materials.

It can be said that in the art of alchemy, Yang Kai has unique conditions that many people cannot match. Although it cannot be compared with Xia Ningshang's Medicine Spirit Holy Body, the conditions are much better than other alchemists.

He poured out all the low-quality materials purchased in the Black Book Space and took out the small incense burner.

This incense burner is a treasure that appeared when the third page of the black book was unsealed, but since she learned about the mystery of the true alchemy skills, Yang Kai knew that it was not just an ordinary incense burner.

It is also a elixir furnace that can be used to refine alchemy!

This incense burner and the alchemy true art should coexist, complementing each other, but for some reason, the alchemy true art is hidden in the statue of the alchemy saint in the Medicine King Valley. If there was no accident, Yang Kai might have missed the secret of the alchemy true art.

The original owner of the Black Book seemed to intentionally prevent Yang Kai from taking the path of alchemy and did not mean to convey the true alchemy skills.

But it turns out that his plan failed.

He reached out and stroked the small incense burner, Yang Kai poured his true energy into it, and followed a certain route to let the true energy wander in the incense burner.

Soon, lines of light flashed on the incense burner. As the light appeared, the small incense burner suddenly expanded and became as big as a water tank.

Yang Kai stopped and nodded with satisfaction.

To a certain extent, the size of the alchemy furnace can intuitively reflect whether an alchemist's skill is exquisite.

The larger the alchemy furnace you need, the worse the level of this alchemist, because when refining alchemist, the alchemist needs to use true energy to carve different spiritual arrays in the alchemist, so that the spiritual array can work, integrate and stimulate the effect of medicine, let the medicinal materials conflict in the alchemist, and finally condense the elixir.

The skilled alchemist can accurately carve the spiritual array no matter how small the alchemy furnace is. There will be no deviation and can also master the temperature.

The alchemy furnace the size of a water tank is suitable for Yang Kai’s practice. Such a large alchemy furnace has a slightly higher tolerance rate, so it doesn’t matter if it is filled with more true energy.

Recalling the configuration of a elixir, Yang Kai found the corresponding medicinal materials from the pile of low-quality materials, put them aside, and then continued to print out the marks with his hands, pouring true energy into the elixir furnace.

Soon, a simple spiritual array was formed in the alchemy furnace.

Because you need to practice, Yang Kai chose a spiritual array that increases the success rate of alchemy. This spiritual array is a basic spiritual array, and it is not too complicated.

Yang Kai has the ability to control the formation and stability of this spiritual array.

After checking the spiritual array in the lower alchemy furnace, Yang Kai was extremely satisfied.

Put the selected low-quality materials into the alchemy furnace in sequence, and pour the true energy into the same while putting them in, and use the hot true yang energy to condense the effect of the medicine.

In this process, the precious experiences and experiences of the alchemy masters in the true alchemy skills appeared in Yang Kai's mind bit by bit, allowing him to use them to compare them with the situation in front of him.

These alchemy masters once knew nothing about the way of alchemy and had nothing to do with the mystery of alchemy.

But through their own efforts and talents, they have reached a height that is admirable step by step.

Yang Kai was careful because the amount of true energy was poured directly related to the condensation of the medicinal effect. If the amount of the medicinal material was poured, the medicinal material might be burned. If the amount of the medicinal effect was not fully exerted, and it would not be able to become a pill.

Alchemy is an extremely delicate job and has strict requirements on the control of one's own true essence.

The herbs of each plant melted under the influence of Yang Kai Zhenyuan and merged together, causing a delightful change.

However, just when Yang Kai thought this time would be almost successful, a stream of black smoke suddenly appeared from the elixir furnace, and the burnt smell quickly filled the room.

Yang Kai stopped pouring his true energy into his body and frowned.

He knew that this alchemy was completely failed. It seemed that there was still some problem with his true energy injected, and the strength he used was a little bit greater, which led to the burning of all the medicinal materials.
