A week passed quickly, and a week later, Zhan Chen went to see Grand Elder Chu Danqing again. After the ceremony, the two sat down, and Chu Danqing said to Zhan Chen: "Zhan Chen, your alchemy technique has reached the point of being extremely proficient, but I think you are still lacking in the theory of alchemy, which has caused you to be deficient and deficient in many aspects, which needs to be improved. ”

Zhan Chen arched his hand and said, "Hope for the Great Elder to give advice." ”

Chu Danqing nodded and said, "I am a truth-telling person, and I will teach you the one-hand furnace control technique today, which is a skill that you have never used in the alchemy process before." ”

"Oh, is the furnace control technique a way to control the Dan furnace?" Zhan Chen, as the name suggests, asked curiously.

Chu Danqing stroked his beard, nodded and replied: "Yes, the furnace control technique is very important, it can timely and accurately control the shape and temperature of the furnace according to the material of the elixir, adjust the environment in the Dan furnace, and further quench the impurities in the pill that will be refined." Not only can it reduce the true element consumption of our generation in the process of alchemy, but it can also better retain the ingredients and spirituality in the elixir, thereby increasing the rate of becoming a pill and refining the grade of the elixir. ”

After listening to Chu Danqing's narration, Zhan Chen was extremely curious, it was the first time he heard that there was such a magical alchemy technique, and he thought to himself: "This Great Elder Chu is really worthy of his reputation, originally I thought that my alchemy technique could already be regarded as entering the house, but when I heard him say this, I felt like a frog at the bottom of the well, and Yelang was arrogant." ”

He saw Chu Danqing's eyes reminiscing again, and said, "I once used the furnace control technique to refine the highest three-turn, eight-grade top-level elixir. ”

"Have you refined the Three-Turn Pill?" Zhan Chen asked in surprise, he knew how difficult it was to refine the Three-Turn Pill, if it weren't for the magical effect of the Nine-Turn Flame Phoenix Furnace and the Nirvana Divine Flame, I was afraid that he wouldn't be able to refine the One-Turn Pill.

"Yes, I did do it, Zhan Chen, I am optimistic about you, if you can continue to improve your alchemy skills as I said, then one day, I believe you can do it too." ”

Zhan Chen listened to his words, silently, but made a decision in private, that is, he must not expose the fact that he can refine the Nine Turns Golden Pill in this Xuan Dao Sect, because there is a great alchemy expert here, if Chu Danqing knows that there is a Nine Turns Golden Pill, he will inevitably investigate to the end, and how much trouble will it cause when the time comes?

This is, Chu Danqing suddenly took out a jade slip from his arms, handed it to him, and said to him: "Zhan Chen, you take this as a meeting gift for you." ”

Zhan Chen took the jade slip and looked at it, there were four big characters written on it, "Baicao Jijing", and heard Chu Danqing say: "This "Baicao Jijing" is written by reading all kinds of classics and tasting all kinds of elixirs in my life, including a total of 3,863 kinds of elixirs from one to nine grades. It also records the pharmacology, efficacy, properties, and advisability of these elixirs, as well as what kind of flame should be used in the refining and melting process, how long it takes to achieve full extraction, and retain spirituality. ”

Zhan Chen excitedly stroked this jade slip and said, "Master, this is your life's work, it is so precious!"

"It's nothing, as a qualified alchemist, you have to fully understand these things. Otherwise, how can we refine the best elixir? Therefore, when each of my disciples worships under my disciples, I will give them this book. Remember, this book is not dead, it is alive, and I hope you can do it, improve it if you find something wrong or wrong, and add to it if you have any new discoveries or gains. Only in this way can this "Hundred Herbs Collection Sutra" be truly transformed into your own thing, understand?"

"Disciple understands!" Zhan Chen immediately stood up and saluted Chu Danqing. The Great Elder's words were like an initiation, which made him suddenly understand how to become a truly qualified alchemist.

What is a breakthrough? Zhan Chen felt that after listening to his words, he had already broken through the original bottleneck in alchemy today.

"Zhan Chen, now I will teach you this furnace control technique, you come with me. With that, Chu Danqing got up and moved to an alchemy room in the back.

And Zhan Chen also followed him into the house, looked around, and found that this alchemy room was neatly furnished and had a thick aura. On both sides, there are dozens of large and small Dan furnaces, the large ones are more than half a person tall and more than two meters in diameter, and the small ones can be placed in the palm of your hand.

Chu Danqing saw that he was very interested in these Dan furnaces, and said: "These Dan furnaces are all used by me for ordinary alchemy. ”

Zhan Chen looked back at him and said strangely, "Do you usually use so many Dan furnaces for alchemy?"

Chu Danqing smiled slightly and replied: "Yes, alchemy is a delicate art, no detail can be missed, I choose different alchemy furnaces according to the different types of pills refined." And the reason why I put these alchemy furnaces here is because I opened a large spirit gathering array here, and I also sprinkled yuan stone crushed powder in these furnaces, so that they can bathe in the aura at all times and cultivate spirituality. ”

Zhan Chen sighed: "I never thought that alchemy would be so particular before. ”

When the two came to the center, Chu Danqing did not take any of the Dan furnaces on both sides, but took out another Dan furnace from his Qiankun bag and placed it in the center to demonstrate to Zhan Chen.

I only heard him say: "Zhan Chen, you look at my demonstration first, my furnace control technique has thirty-six seals, the first twenty-four are used for fire control, which is equivalent to a fire control technique, and the last twelve are used in the process of becoming a pill, such as further forcing out the impurities in the pill or making the shape of the pill more complete and evenly distributed. Now I'll take refining a most basic four-rank pill as an example. ”

Chu Danqing said as he took out a few elixirs from the Qiankun bag, first took out one of them and put it into the Dan furnace, and raised the fire to roast the elixir. Suddenly, Zhan Chen observed, his fingers moved quickly, and he quickly pinched out a seal to hit the furnace wall, and a magical scene appeared, the flame in the furnace suddenly burst into flames, like a flower bone blooming with buds, wrapping the entire elixir and burning evenly.

Grand Elder Chu explained on the side: "This is the first seal of the furnace control technique I taught you, the 'Blooming Seal', which is used in the early stage of refining the elixir, it can not only make the elixir more evenly and well-refined, avoid the loss of the active ingredients of the elixir, but also improve the efficiency of refining and save the consumption of true yuan, have you remembered?"

Zhan Chen nodded solemnly. Chu Danqing was not at ease, and in the following refining process, he cast the Blooming Seal several times and emphasized the details.

At this time, all the elixirs had been extracted, and it was time for Ning Dan to be consumed, and Zhan Chen saw that Elder Chu had cast another seal.

With the casting of this seal, the liquid medicine suspended on the surface of the furnace fire turned into a whirlpool, rotating around the center at high speed. From the outside, it looked like a small funnel, and at this time, Zhan Chen saw that some small impurities in black and white kept falling from the bottom of the "funnel", falling into the flames and turning into a trace of white gas.

Sure enough, Chu Danqing explained to him again: "This seal is called 'Copper Leak Seal', which is used to further filter out some impurities in the elixir extract that are difficult to be cremated by the furnace, so that the refined elixir is purer and of higher quality!"

This process of refining lasted for about a quarter of an hour, and Chu Danqing played a series of condensing pill seals to refine the pill and warm it.

After opening the lid of the furnace, he took out the pill and showed it to Zhan Chen, the emerald green pill emitted a red, orange, and yellow glow.

"This is the Third Turn Golden Pill!" Zhan Chen immediately reacted.

"Yes, knowledgeable!" Chu Danqing looked at Zhan Chen, but a trace of surprise flashed in his eyes, surprised that this Zhan Chen's calmness was not like the other apprentices he had taught, and he was extremely envious when he saw the three-turn pill for the first time.

"Teacher, you have truly mastered the method of refining the golden pill. Zhan Chen said with sincere admiration, this was the first person he had ever seen who could refine the three-turn golden pill besides himself. It's just that he relies on the Nine Turns Yanhuang Furnace, and Chu Danqing relies on his true skills.

"Zhan Chen, this is nothing, you must know that the ultimate goal of the alchemist is to refine the Nine Turns Golden Pill, and I still have a long way to go. Chu Danqing paused, and then said: "Today's class will be here first, you go back and digest what you have learned, and I will evaluate you next time." ”

"Yes!" Zhan Chen saluted him, got up and said, "The student has retired first." With that, he turned and left.

When he returned home, Zhan Chen immediately reviewed the two seals that Chu Danqing had given him, and began to read the "Hundred Herbs Collection Sutra" he gave him in detail. He had already realized that in the past, in the process of refining the elixir, he relied too much on the "artifact" of the Nine Turns Flame Phoenix Furnace, and in this way, his alchemy technique had improved very slowly, and it could even be said that it had stopped.

Therefore, he has decided to put aside the Nine Turns Yanhuang Furnace first, follow Chu Danqing in a down-to-earth manner, and learn from beginning to end, starting with "walking" first.

Spring goes to summer, half a year passes in a blink of an eye, in the process of learning for half a year, Zhan Chen has lived a very fulfilling day every day, he has put his main energy on learning alchemy, and the rest of the time will also be used to comprehend and comprehend the "Silent Killing Sword", or use the Heavenly Star Stone to hone his divine sense. Of course, the emotional cultivation with Su Yun has not been left behind.

In the past six months, his cultivation has not improved significantly, and the Heavenly Rank Sword Technique is still in the clouds, and his divine sense has not advanced an inch. However, he made a major breakthrough in alchemy, not only mastering all the 36 kinds of seals of the "Hundred Herbs Sutra" and the furnace control technique taught to him by the teacher, but also applying them to practice refining many pills.

On this day, it is finally time to graduate, as long as he passes today's assessment, he will perform his duties in Nanhua Peak as an alchemist.

In the alchemy room, Chu Danqing sat opposite him, and an alchemy furnace the size of a basketball was placed in the middle.

Zhan Chen stared at his teacher opposite, took a deep breath, and couldn't help but complain in his heart: "What the hell today! I have refined so many pills, but how can I still be nervous in the face of this small assessment?" Yes, this even he felt incredible.

Chu Danqing spoke, his voice still seemed so serious and deep: "Zhan Chen, today is the time for you to leave the school, my exam question is to refine a sixth-grade high-grade 'Liuyun Pill', perform well, don't let the teacher down, there are the prescriptions for the elixir and the elixir needed for refining, you go and prepare first, and in a quarter of an hour, we will start the exam immediately!"

While saying that, Chu Danqing took out a Qiankun bag and handed it to him, Zhan Chen took the Qiankun bag nervously, but he was thinking in his heart: "Liuyun Pill, this is an elixir that I have never refined, can I meet the teacher's assessment standards?"

During the time he spent with Elder Chu, Zhan Chen gradually learned that this Yan Master would only repay the apprentices who were able to get out of the Dan Halo, and he had never succeeded once in his previous studies.
