Time passed slowly, and in the alchemy room, the Dan furnace was scorched and burned by flames.

Chu Duan stood in front of the Dan furnace, his hands changed, like a round of morning sun rising into the sky, bursting with wisps of golden-red light, gradually going up, the light became more and more intense, and the temperature in the Dan furnace became higher and higher, turning into a round of scorching sun, wantonly emitting a scorching heat, as if to melt everything.

After the last day, Chu Duan's hands changed again, gradually sinking, the light became more and more restrained, and gradually turned red, becoming the setting sun.

The Nine Transformations of Tianyang were completed, and the pill in the Dan furnace was also formed.

Both hands slapped on both sides of the Dan furnace, the lid of the furnace flew up, and one by one the pills spurted out of it, and they were all grabbed by Chu Duan's divine thoughts.

The lid of the furnace fell, the flames were extinguished at the same time, and Chu Duan put all the ten vitality pills into the jade bottle, and walked to the door of the alchemy room with the jade bottle.

Opening the door of the alchemy room, the bearded and red-faced old man immediately turned around, and his eyes fell on the jade bottle in Chu Duan's hand: "Refined?"

Chu Duan nodded, handed the jade bottle to the old man, and the old man immediately took it, uncorked it, poured out three Vitality Pills, and glanced at it.

"There is also a fiery breath, it is indeed a freshly baked elixir. The old man nodded, with his great grandmaster's Dan Dao attainments, whether it was a freshly baked pill or not, it could be seen at a glance, and it was absolutely impossible to fake.

The turquoise vitality pill was smooth and round, crystal clear, and there was no fragrance of the pill, the old man stared at it with wide eyes, and gradually shrunk, completely concentrating on one of the pills, looked at it, and sniffed it with his nose closer, and after repeating this several times, the expression on his face became more and more surprised.

"The color is as round as a flawless gem, and the danxiang is restrained ......" The red-faced old man nodded secretly and whispered in surprise: "This is clearly the embodiment of the infinite proximity of quality to perfection." ”

"You can actually refine a perfect quality elixir......" The red-faced old man was extremely surprised, looking Chu Duan up and down, looking incredulous.

Good for a while. The old man regained his calm on the surface, but he was still a little surprised inside.

"It seems that you have a very high attainment in alchemy, and your foundation is also very solid, which shows that you have worked hard. The red-faced old man said: "With this furnace of vitality pills alone, you can pass the alliance's Dan Dao Grandmaster assessment, are you sure you want to take the Great Grandmaster certification assessment?"

Chu Duan nodded.

"That's fine. The red-faced old man paid a lot of attention to Chu Duan: "Although there is a one-word difference between the Dan Dao Grandmaster and the Dan Dao Grand Master, the difference in their attainments in alchemy is huge. Some alchemists are unable to break through and become great masters in their lifetime. ”

As he spoke, the old man took Chu Duan to the assessment place of the Great Grandmaster of the Dan Dao.

There were three people in charge of the assessment, three old men, and the bearded and red-faced old man before was one of them.

"The content of the assessment is to refine the earth-grade pill, as for what kind of ground-grade pill to refine, it depends on your luck. The red-faced old man said to Chu Duan, because of this assessment. It was Chu Duan who drew a Dan Fang by himself.

There are a total of ten Danfang, and you can't use the power of divine thoughts to probe, and you can choose by random drawing, all by luck.

Chu Duan did not hesitate. He took out a pill and glanced at it, and knew what the pill he wanted to refine in his assessment was.

"Yishen Pill, this is a ground-level elixir that restores the power of divine thoughts. Among the prefecture-level pills, they belong to the low-grade level, and the low-level great masters can just refine them. However, the success rate is not high. The three assessors glanced at Dan Fang, and the red-faced old man said.

"Yishen Pill can also play a role in restoring the power of divine thoughts for ordinary king-level powerhouses, only when you reach the attainments of middle-level great grandmasters, you can refine them freely, ordinary low-level great grandmasters are quite difficult, and they are used for assessment, some of them are difficult, so let's do it, you can draw them again. One of the black-faced old men said to Chu Duan.

The black-faced old man was Aicai, because he also saw the vitality pill refined by Chu Duan, and after seeing Chu Duan himself, he felt that Chu Duan was an alchemy genius who was worth cultivating, and he didn't want him to be hit by setbacks.

"Thank you, Elder, but since you have already chosen, let's refine the Yishen Pill. Chu Duan said, not saying anything big.

These three people are all Great Masters of the Dan Dao, and they are all elders of the Alchemist Alliance.

"Since that's the case, then you can start refining, and we will watch here and give you an evaluation. "The third elder is an old man with a goatee.

Chu Duan nodded, and chose the medicinal herbs first.

The refining of the Vitality Pill just now was just a private assessment by the red-faced Elder Dai to determine whether Chu Duan was eligible to apply for the Great Grandmaster Assessment, so the medicinal materials did not need to be selected by Chu Duan himself.

The current assessment is a formal assessment.

The selection of medicinal materials is also a part of the assessment.

Because an excellent alchemist must personally prepare the medicinal materials, the dosage of the medicinal materials, the placement of the medicinal materials, and so on, and handle everything personally, so as to avoid unnecessary and subtle mistakes that affect the alchemy.

There are many medicinal herbs here, distributed on the walls and shelves around them, and Chu Duan began to select.

The power of divine thought swept across, and among the many complex medicinal materials, Chu Duan made a quick move, selecting all kinds of medicinal materials needed to refine the Beneficial Divine Pill.

Twenty-three are needed in total.

The three elders kept staring at Chu Duan's movements.

"Shoot quickly, without hesitation, the technique is sophisticated, and the cognition and courage of medicinal materials are very good. The black-faced Elder Li nodded and said in a voice that only the three of them could hear.

Chu Duan was not affected in the slightest, and took out one medicinal herb after another.

Because only the amount of Yishen Pill can be refined, the amount of medicinal materials must be accurate.

"Yes, yes, the amount of each medicinal material is exactly the same, and the old man comes to take it, and that's it. The red-faced Elder Dai touched his beard and said with a smile, among the three elders, in terms of the accuracy of taking medicinal materials, Elder Dai should be the best.

"In the process of taking medicinal materials, Chu Duan passed, which is very good. The third goatbeard Yang Elder laughed.

"Let's see how he extracts the essence of the herbs. ”

Put the twenty-three pills in turn, light a fire to control the temperature, and after heating the furnace, adjust the temperature again, and then start to extract the essence of the medicinal herbs.

Whether it was making a fire or heating a furnace or adjusting the size and temperature of the flame afterwards, Chu Duan did it very skillfully, without the slightest jerkiness, which made the three elders nod secretly, judging from this point alone, Chu Duan's basic skills were very solid and stable, better than many alchemists.

The technique used by Chu Duan was the Nine Changes of Tianyang, the technique of the Great Grandmaster, in the eyes of the three elders, he was only a little surprised, but when he thought of Chu Dui's application for the assessment of the Great Grandmaster of the Dan Dao, the technique of knowing the Great Grandmaster level was nothing.

They could also see that Chu Duan had not yet fully mastered that technique.

After the twenty-three medicinal herb essences were extracted, Chu Duan breathed a sigh of relief a little, and then began to refine the Yishen Pill.

Adjust the temperature of the flame to the highest, and when the temperature of the Dan furnace reaches its hottest, the first herb essence is inserted, and then the size and temperature of the flame are controlled, and the second herb essence is inserted after three breaths.

The three elders all stared wide-eyed, they didn't dare to use the power of divine thoughts, for fear of affecting Chu Duan.

"Good, very good, the order of each medicinal essence is correct, and the time interval between each medicinal essence is consistent with the requirements on the Danfang. Elder Yang's tone was a little excited.

Each of the pills that has been handed down has been verified countless times, and the dosage of the medicinal materials on it, the order and interval time of the delivery have all reached the most accurate point.

Although this is the case, not every alchemist can be as accurate as recorded on the Danfang, even if there are slight differences, under normal circumstances, it will not lead to the failure of alchemy, at most, the quality of the Dan will be affected.

However, there is no way to do this, the vast majority of alchemists' grasp of the timing and time interval cannot reach such a subtle level, and those who can achieve it are often true geniuses, obviously, Chu Duan is one of them.

After all the medicinal essence was put in, the furnace lid was closed, and Chu Duan began to refine it by casting the Tianyang Nine Transformations.

The breath was calm, and between the changes of his hands, he turned into a round of rising sunrise, and between the rises, the temperature gradually increased, and the flame under the Dan furnace also changed.

As soon as the technique changed, it became the noon of the scorching sun, and the temperature of the Dan furnace was also raised to the highest, and the power of Chu Duan's divine thoughts also entered the Dan furnace to assist in the melting of medicinal essences.

This process lasted for half an hour, and it consumed a lot of the power of divine thoughts.

Fortunately, Chu Duan's divine power was very strong, and this kind of consumption could not affect his state.

Half an hour later, the hands changed again, slowly sinking to the side, the third change, the setting sun.

At this change, it means that the refining of Yishen Pill has reached the last moment.

The flame of the Dan furnace changed again, the temperature gradually decreased, and it decreased very evenly little by little, and the essence of the medicinal materials in the Dan furnace was also completely melted, and with the cooperation of Chu Duan's divine thoughts, it began to condense into an elixir.

About a quarter of an hour or so passed, the medicinal essence in the Dan furnace fused and became pills one by one, lying quietly at the bottom of the Dan furnace.

This is not completely over, to this step, there is the last step, that is, to use the residual temperature of the Dan furnace to roast the newly formed elixir, so that it is completely formed, fixed, and in this process, the last step is to remove the residual impurities on the surface.

Every step and every link of alchemy is very important, and Chu Duan treats all of them with his heart, and he does not relax his mind because of which step is relatively simple.

At the moment when he became a Dan, Chu Duan still did not relax, because he still had to collect Dan.

If you don't do it well, it is likely to cause the pill to be damaged, and the previous efforts will be wasted, and it will be too late to cry.

The eyes of the three elders widened again...... (To be continued......)
