The blue flame in the dragon dust's hand rose up, and the entire cave immediately appeared with blue light, which looked gorgeous and warm.

"What a beautiful flame"

Tang Wan'er looked at the flame in the palm of the dragon dust, her beautiful eyes were full of fascination, it was the first time she had seen such a beautiful flame, like a ball of flowing seawater.

Long Chen smiled slightly, and found that after mastering the beast fire rune, his control over the beast fire was much stronger, and it was easy to use, and it didn't need to consume too much soul power.

You must know that even if it is the previous flame leopard beast fire, when the dragon dust is used, it needs to be suppressed with the power of the soul, it is like a disobedient beast, if it is not suppressed, it will bite people at any time.

And the dragon dust has mastered the runes, then this beast fire is equivalent to recognizing the dragon dust as the master, and there will be no resistance.

For the intensity, size and rhythm of the flame, he is more free to use, like an arm and a finger, as he wishes.

Long Chen secretly praised himself in his heart, this kind of whimsical approach, only a genius can think of it, if you succeed, you are a genius, but if you fail, you will be scolded as a madman.

So in this world, madmen and geniuses are basically equal, and it just depends on whose luck is better.

Tang Wan'er and Qing Yu'an watched quietly, this was the first time they had watched others alchemy with their own eyes.

Because all alchemists don't like people around them when they are alchemizing, one is afraid of being disturbed and can't meditate, and the other is afraid that people will steal their studies.

Longchen didn't care at all, concentrated all his mind and started to warm the furnace, this is the most basic process, if you don't let the Dan furnace gradually adapt to this process, in the end, there is a danger of frying the furnace, and at the same time, it can also extend the life of the Dan furnace.

When the temperature of the Dan furnace gradually increased, the dragon dust began to slowly put the medicinal materials into the Dan furnace, controlling the flames and refining their essence.

At this time, it is very important to look at the skill, which must be just right for the size of the fire, and at the same time, it is also necessary to know the heating capacity of the medicinal materials clearly.

Otherwise, if the fire is small, it will take a long time to refine, not to mention increasing the refining time, and some of the essence will be lost due to too long time.

If the fire is too big and exceeds the maximum temperature that the herbs can bear, it will immediately burn into ashes, and all the previous efforts will be lost.

However, these are not a matter for the dragon dust who has the memory of Emperor Dan, and there are few people in this world who know the critical point of medicinal materials better than him.

Now that he has mastered the rune of the salamander beast fire, the blue flame is no different from the natal fire to him, and with the power of his strong soul, he can achieve subtle control.

The refining speed of dragon dust was very fast, and after refining several medicinal materials into powder, he asked Tang Wan'er and Qingyu to help, took out a smooth piece of paper, and poured the medicinal powder on it.

Ask them to spread out the powder, and when the heat is gone, divide them in a certain proportion and wrap them into paper packets.

And while they were doing things carefully, Dragon Dust had already begun to refine the next batch of medicinal herbs.

They had just finished the task arranged by Dragon Dust, and the second batch of Dragon Dust powder had already been refined.

However, this time, the medicinal powder was separated from the original medicinal powder and repackaged, and this was repeated seven times, and the dragon dust refined all the medicinal materials, and the dragon dust was not good, but it drenched Tang Wan'er and Qingyu's busy fragrant sweat.

Because I was too nervous, after all, this was alchemy, and a little mistake could lead to the failure of alchemy, so I was so careful.

"Okay, the refining is complete, now the medicinal powder is divided into seven kinds, according to the order just now, just sprinkle a pack on the Dan furnace each time, as for when to vote, I will remind you, okay, I'm going to start." "Dragon Dust Road.

"Dragon dust and so on," Tang Wan'er said.

"How?"

"I'm a little nervous about that," Tang Wan'er said a little embarrassed, she was afraid that something would go wrong in a while.

Longchen smiled: "What are you nervous about, even if you fail, that's my responsibility, you should be a child."

Hearing the laughter of the dragon dust, Tang Wan'er felt a lot more relaxed, and couldn't help but smile slightly, looking at these small medicine bags in front of her, it was really like playing with sand when she was a child.

Call!

The flames in the dragon dust's hands skyrocketed, and a terrifying heat rose up, sending the Dan fire under the Dan furnace.

"Let's get started, put the first pack first, take it easy"

Tang Wan'er nodded, and carefully poured the medicinal powder into the Dan furnace, and with the power of the dragon dust's flames, those powders seemed to melt slowly and turned into a sticky liquid, which was very magical.

What she didn't know was that those powders were the essence of all the herbs, not the real powders.

Long Chen stared at the Dan Furnace intently, his expression was solemn, this was the first time he had refined a third-order pill, although he knew the refining method, but he had no practical experience, he didn't dare to be careless.

No matter how powerful Dan Xiu is, it is impossible to guarantee a 100% success rate, not to mention that this is the first time for Dragon Dust.

Looking at the dragon dust that was engrossed, a trace of intoxication flashed in Tang Wan'er's beautiful eyes, the dragon dust at this time was extremely attractive, completely lacking the usual hippie smile, and it seemed more calm and reliable.

"The second type"

Longchen said softly, Tang Wan'er was startled, she was distracted just now, but fortunately, Qingyu was also preparing on the side, and hurriedly sprinkled the medicinal powder in her hand into the Dan furnace.

Tang Wan'er's face flushed, and she glanced at Qingyu apologetically, but Qingyu just winked at her and didn't blame her.

Tang Wan'er's pretty face turned even redder, and she hurriedly eliminated distracting thoughts, stared carefully at the Dan furnace in front of the dragon dust, and didn't dare to look at the dragon dust's face anymore.

The reason why Longchen let Tang Wan'er and Qingyu stay was mainly because he had to control the size of the fire wholeheartedly and observe the changes in the medicinal powder.

If you add your own medicinal herbs, you will be distracted, and on the way to alchemy, the slightest mistake may cause failure.

Especially these pills, but it is related to the fate of the entire guild, he is even more careless, he takes the points of the guild to do things for himself, he is a little unhappy in his heart, this time he must practice well.

Time passed unconsciously, an hour passed, and all the seven medicinal powders were placed in the Dan furnace, and the dragon dust had already sealed the furnace and began to increase the output of flames.

The blue flames writhed, a rune loomed, and the temperature in the room began to rise rapidly.

Tang Wan'er and Qingyu didn't seem to feel the terrifying heat, and looked at the blue flame in Long Chen's hand with shocked expressions.

"Runes?"

Tang Wan'er was the most shocked, she had shown her runes to Longchen before, and she had also seen that Longchen wanted to imitate her runes, but unfortunately failed.

At that time, she thought that dragon dust was whimsical, and such a crazy idea could be generated, without ancestral bloodline, how could it be possible to condense runes.

However, the color of the Dan Fire in Long Chen's hand changed, and there was a rune, although the rune was not obvious, but the power of the rune was indeed very clear.

Tang Wan'er, who also mastered the power of runes, knew that it was because Longchen did not run the runes at full strength, not that he did not master them properly.

It was precisely because she understood that she was shocked and couldn't believe that since ancient times, no one seemed to have done this, not even in the history books.

"How about it? I use this flame to grill fish or something, it should be okay, right?" Although Long Chen's mouth was relaxed, the smug look on his face could be seen clearly by a blind person.

"Where did you get this flame?" Tang Wan'er couldn't help but ask.

"Stolen"

Long Chen said with a smile, now that the situation in the Dan furnace has stabilized, there is no need to be so engrossed, and he can be distracted and chat.

Tang Wan'er glared at Long Chen, knowing that this guy didn't even have two truths out of ten sentences.

However, this kind of thing is not easy to dig out the roots and stabilize, after all, powerful means are the foundation of a cultivator's life, rashly inquiring, and the prisoner is taboo.

Seeing that Tang Wan'er didn't ask, knowing what she was afraid of, he was just about to tell the source of his beast fire, when suddenly the Dan furnace trembled.

"It's going to be a Dan"

The dragon dust was overjoyed, and the power of the flames continued to slowly increase, while his right hand slowly covered the lid of the furnace.

"Boom, boom, boom......"

The Dan furnace continued to explode, and the terrifying energy flowed rapidly, as if there was a violent hurricane inside, spinning constantly.

"This is the precursor of Cheng Dan, all the medicinal liquid is concentrated together, and at this time, under the strong urging of the flames, it will automatically separate as if it is alive, forming a small ball.

And the small ball runs wildly in the Dan furnace, absorbing the aura of heaven and earth, forming an outer coat, and wrapping the essence inside in the core.

Originally, their bodies were three flat and four not round, but after such a crazy rotation, they became a very standard Dan shape.

The whole process is like the formation of a fetus, which is very magical and incredible," Long Chen explained to the curious two.

Although Longchen knew that alchemy was the principle of everything, he had a deep awe for alchemy, which was a divine skill, a divine skill that turned decay into magic.

"Boom"

Suddenly, the Dan furnace made a loud noise, and then it slowly calmed down, and the dragon dust slowly lifted the lid of the furnace.

An extremely rich Dan incense filled the entire cave, and the nine full pills, like pearls, lay quietly in the Dan furnace.

"Oh my God, there is a Dan Halo, it is a top-grade pill, there are as many as five" Tang Wan'er exclaimed.

Longchen didn't expect that this time it was originally a work of practice, and he thought it would be good to have a high-grade elixir, but he didn't expect that there would be as many as five.

After being stunned for a moment, Longchen immediately understood that this was the credit of the Spirit Stone Formation, and it seemed that the Spirit Stone Formation was much more powerful than he imagined.

"Dragon dust, you see that there are five top-grade solid tendon pills, and the rest are all medium-grade pills with Dan patterns, dragon dust, you are too powerful" Tang Wan'er held the pill, smiling like a flower, and said excitedly.

"Alas, sure enough, it is a fist that does not leave the hand and does not leave the mouth, and I don't practice my hand for three days, I remember that I used to refine such an elixir with my eyes closed, and it was all of the highest grade" Long Chen shook his head and sighed, with a dissatisfied face.

Tang Wan'er was stunned for a moment, then rolled her eyes, ignored the dragon dust anymore, and looked at the just-baked Gujin Pill with a happy face, and her beautiful eyes were full of joy.

With the first experience, Longchen knew all the nodes of the fire, and the speed of the second furnace increased rapidly, and it only took a quarter of an hour for the first furnace to succeed again.

What made Tang Wan'er and Qingyu stunned was that the nine pills were full of grains, and the halo was circulating, and all of them were top-grade Guteng Pills.

When all the medicinal powder was refined, Tang Wa'er stared at the table, the more than one hundred and ten Gutendon Pills were simply stupid.

Long Chen practiced so many pills in one go, although he could refine at least one or two thousand pills like this, but after finishing speaking, he went directly into the bed like a dead pig and fell asleep.

After Tang Wan'er and Qingyu were shocked, they began to distribute these high-grade Gujian Pills, and the next day, Longchen woke up.

Long Chen looked at the jade plaque in his hand, and the huge white figure came to mind.
