The refining of the Nine Pins Pill is not easy, especially when the conditions are simple.

The middle-aged alchemist of Tiandanlou was engrossed, took out twelve points of attention, and forgot everything around him, at this time, if someone made a move, even if it was a swordsman who was many times lower than him, he would be able to kill him with one sword.

His attainments in alchemy have reached the pinnacle of masters, and he is only one step away from the grandmaster, and he is one of the alchemy masters with a very high status in the Tiandan Building, not to mention the nine-rank pill, even if it is a ten-rank pill, he can also refine it.

However, due to the limited conditions, only the Nine Pins Pill can be selected to ensure the final champion.

There is only one chance, he must focus and focus, and he must not fail because of a little negligence.

Chu Duan also began to refine the elixir, Chen Qigu kept staring at Chu Duan, remembering the order and time difference between Chu Duan's injection of medicinal essence and the time difference, and searched again, but he still didn't know what kind of elixir Chu Duan wanted to refine.

He no longer subjectively assumed that Chu Duan was breaking the jar.

Chu Duan was also very focused, this was the first time he had refined the Nine Rank Pill, as for the conditions, it didn't matter, because until now, Chu Duan had not used a better alchemy condition.

Bronze Dan furnace plus ink carbon!

There were a lot of people watching around, densely packed inside and outside three circles, and most of the attention fell on the alchemists of Tiandan Tower, and only a very small number of people noticed Chu Duan.

Nalan Fenghua and the others did not speak, but their expressions were full of encouragement and expectation, silent encouragement, and they kept cheering and praying for Chu Duan in their hearts.

They all hope that Chu Duan will win, and only with this result can Nalan Fenghua get rid of the fate arranged by the family, she is a gentle person on the outside, but she has her own stubbornness in her heart.

More than a dozen kinds of medicinal herb essences were all put into the Dan furnace, and Chu Duan's spiritual thoughts participated in the whole process. All the time in the Dan furnace, when more than a dozen kinds of medicinal material essence converged, Chu Duan's spiritual mind came to life, wrapping each ball of medicinal material essence, so that more than a dozen kinds of medicinal material essence produced a real fusion.

The flame of the burning ink carbon brought high temperature to the Bronze Dan Furnace, and this high temperature entered the Bronze Dan Furnace and was somewhat dispersed, and Chu Duan effectively controlled these high temperatures.

The refining of the elixir is not a blind pursuit of high temperature, which will make the refining of the elixir fail. Becomes a waste residue.

Controlling the temperature change is a very important knowledge, and it is also a precise skill that must be mastered in the way of alchemy.

Chu Duan did obtain the inheritance of the Great Grandmaster of Alchemy, but compared to other alchemists, the time he had stepped into the path of alchemy was still very short, even if he had a demonic understanding and could comprehend and master it extremely quickly, he also lacked enough practice, which was a valuable experience.

Fortunately, Chu Duan has a strong spiritual mind. Even the alchemy master has an incomparable advantage, and he makes full use of this advantage to serve the alchemy and achieve better results.

Precise control of temperature. It makes the fusion of more than a dozen medicinal essences more efficient and thorough, and at the same time, Chu Duan also tries his best to squeeze out the impurities in the fusion process of medicinal essence to improve the purity of medicinal essence as much as possible.

Alchemy Master. I can't do this, and the second extraction is still in the process of melting the essence of medicinal herbs.

Little by little, time passed. But no one was aware that it was a crucial final and almost everyone held their breath.

The refining of the Nine Pins Pill was not easy, and it took more time.

In the blink of an eye, an hour passed, and the medicinal essence was still being smelted.

When the second hour had passed, the medicinal essence had been refined.

At this time, the middle-aged alchemist of Tiandan Lou began to feel tired, kept a high degree of vigilance for a long time, and constantly performed alchemy techniques, which was a double consumption and a double load for mental and physical strength.

On the other hand, Chu Duan, calm and relaxed, with a calm attitude, as if he was taking a leisurely walk, it looked like he was refining the Nine Pins Pill.

The strong spiritual intent, even if it is two more hours, will not be consumed, and the powerful Heavenly Desolate Sword Body brings him enough physical strength, endurance and recovery power.

Now, it's time to get to the last step, Cheng Dan!

More than a dozen medicinal essences were melted, and in the end, it was impossible to form only one pill.

However, the higher the grade of the pill, the lower the number of pills, which is common sense and law.

The number of Cheng Dan is also one of the key points of the competition, and the other focus is the quality of the pill, of course, the grade of the pill is also the focus of the competition, but the alchemists of Chu Duan and Tiandan Lou both refine the Nine Rank Pill, and the grade is the same, and there is no comparison.

Cheng Dan is an extremely critical step, if you are not careful, you will fail, and you can only get a cloud of waste residue.

Chu Duan's spiritual mind is still involved in the process of becoming a Dan, promoting assistance.

And he was also able to see the condensation and formation of the pill more clearly through his spiritual thoughts, allowing him to have a deeper cognition and understanding of the way of alchemy.

Half an hour, this process lasted for half an hour.

On the other side, the middle-aged alchemist of Tiandan Tower had already finished becoming a Dan, and I saw him take a deep breath, and there was a slight sweat on his forehead.

After three breaths, he slowly exhaled a long breath, and then, with both hands, he opened the lid of the bronze pill furnace, and a scorching breath was the first to erupt, and then, a rich fragrance of the pill diffused, slowly wafting and spreading.

"Dan is done. The Lord of Tiandan Mansion and the elders of Tiandan Tower showed joy one after another, clenching their fists with some excitement, their faces full of joy and hope.

They firmly believe that victory should be the Tiandan Tower, and Xiao Dange must leave the border desert city.

After receiving the pill and baking it, the two full and shiny red pills attracted the attention of countless people, and the alchemist of Tiandan Lou also showed a smile when he looked at the two pills.

Using the bronze pill furnace and ink carbon, something he hadn't used for many years, refining the Nine Rank Pill, and finally counting two pills into the pill, he thought it was good.

This elixir was presented to Chen Qigu, but Chen Qigu only glanced at the elixir, did not immediately identify it, and his attention was still focused on Chu Duan, which made the middle-aged alchemist of Tiandanlou frown slightly, and seemed to be a little dissatisfied.

"Elder Chen, you can identify it. Tiandanlou felt that victory was in sight, and the champion was already beckoning, so he couldn't hold back and said.

"Wait, he's not done yet. Chen Qigu replied casually.

Tiandanlou only then remembered that Chu Duan was a master who at least possessed the strength of the Yuan Extreme Realm.

Fortunately, there is no time limit for alchemy, otherwise Chu Duan would have lost.

Another quarter of an hour or so passed, and Chu Duan opened the lid of the furnace at a lightning speed, and a white heat like smoke rushed out, and everyone who watched seemed to be able to feel the scorching heat.

Then, there was a light fragrance of elixir.

It is not easy to judge the quality of the elixir from the fragrance of the elixir alone, because different elixirs have different fragrances, but if it is a perfect quality elixir, it will not emit the elixir.

When the harvest pill was baked, everyone found that Chu Duan's number of Cheng Dan was actually three.

Just looking at the number of Dan, it has surpassed the middle-aged alchemist of Tiandan Tower.

"The quality is definitely not as good as my elixir. The alchemist glanced at it and said secretly.

"Bring the pill up. Chen Qigu hurriedly clapped his hands and said.

The pills were quickly presented in front of him, and two different pills were placed on the left and right, for Chen Qigu to identify.

Chen Qigu first glanced at it a few times, and then identified the Nine Rank Pill refined by the middle-aged alchemist of Tiandan Building.

About half an hour later, Chen Qigu finished his appraisal, raised his head, and his gaze swept around, finally landing on the face of the middle-aged alchemist in the Tiandan Tower.

"Red Pulp Pill, Nine Rank Pill, is an elixir suitable for Qi Sea Realm swordsmen to treat internal injuries. Chen Qigu spoke slowly, his voice was not loud, but everyone present could hear it clearly: "Under the condition of using only the bronze pill furnace and ink carbon, you can refine the red marrow pill, and the number of pills can reach two, it is indeed very good, if I am not mistaken, you are already at the peak of the alchemy master, and you are only a line away from the grandmaster." ”

Many people were shocked, but the people of Tiandanlou were full of pride, the peak of alchemy masters, such a talent is rare.

Subconsciously, almost everyone thinks that the champion belongs to whom.

Chu Duan didn't have any unusual expression, and Chen Qigu's words were not finished yet.

"After my appraisal, the quality of the Red Pulp Pill you refined is barely excellent. Chen Qigu made a conclusion and said.

Under such conditions, it is indeed rare to be able to refine a high-quality Nine Rank Pill, even if it is only barely achieved.

Then, Chen Qigu began to identify the elixir refined by Chu Duan, looking at it, the doubts on Chen Qigu's face became more and more obvious, and even he pinched a milky white pill with his index finger and thumb, sniffed it, and then picked it up and looked up from all angles.

A quarter of an hour has passed, and Chen Qigu is still appraising.

"It can't be a fake Dan, right?" someone whispered when they saw this.

The so-called fake pill is that it looks like a pill on the outside, and the taste is also a pill, but in fact, there is no effect of the pill, and there is no benefit of the pill when taken down, it may just taste okay.

Some scumbags in the alchemy world, in order to seek property and so on, may refine fake pills and sell them.

The whispering discussion about the fake pill gradually spread, and more and more people thought that it was a fake pill, otherwise, as one of the elders of the Alchemist Alliance, how could Chen Qigu, the alchemy master, not identify it for so long?

It can only be explained that it is a very clever fake pill, so that Chen Qigu, the grandmaster, cannot accurately judge for a while, and can only observe again and again.

Nalan Fenghua and the others also heard the remarks of the fake Dan, and the maid Xiaohuan even quarreled with others, and Qin Yang was also so angry that his face was red and his neck was thick.

Only Chu Duan's face did not change, as if he hadn't heard anything, only he knew what kind of elixir it was. (To be continued......)
