Yang Qi returned to the state religion, and at this time Humble Feng was still empty, so he immediately sorted out all the chores at home, otherwise Shang Ruoyu would have to criticize and punish him when he came back. With Yang Qi's current cultivation, it is really easy to organize the work, and within three hours, all today's things will be completed. Immediately afterwards, he and Bai Zisu came to the green pine forest, found a hidden depth, and began to refine the pure ingot.

When Bai Zisu came to the depths of the green pine forest, he immediately took out a bronze Dan furnace from the storage bag, and said leisurely: "Xiao Yangzi, there are four grades of Dan furnace, from good to inferior, which can be divided into gold, silver, bronze, and black iron. And the old man's Dan furnace is the bronze ranks. Originally, with the status of the old man in his heyday, he should use the golden pill furnace, but the changes of that year not only made the old man out of his body, but even destroyed all his belongings. ”

When Yang Qi heard this, he didn't say much, knowing that only by cultivating himself can he help the teacher respect and return to the peak, and the rest of the things are groundless. Bai Zisu said again: "Today, the old man not only wants to refine the Pure Yuan Pill for you, but also to pass on your introductory knowledge of alchemy, and then you need to remember all the details of the old man's alchemy, and you can't ignore the slightest bit." Chunyuan Dan is a second-grade pill, which does not meet the homework you need to master to get started now, but there is a reason for it, and it can't give you the most suitable practice. However, it is the same as ever-changing, although it is a second-grade elixir, but if it is observed properly, it can also gain a lot of insight. ”

Yang Qi nodded, and then his gaze fell on Bai Zisu, which could be said to be preoccupied, and he didn't dare to slack off for half a minute. I saw the bronze Dan furnace hanging in the air, Bai Zisu's right palm was lightly raised, and a flame suddenly appeared, which was the only fire of consciousness condensed by the Heavenly Master's divine sense. Throw the fire into the Dan furnace, wait for a while, the flame in the furnace is blazing, and then put the medicinal herbs inside, and the two begin to blend. From beginning to end, Bai Zisu's movements were really smooth and familiar, but the serious look on his face did not weaken in the slightest.

Bai Zisu said while controlling the flames in the Dan furnace: "Xiao Yangzi, you have to keep in mind that the most important thing in the alchemy of the Heavenly Master has always been to be calm and concentrated. To control the fire with divine sense, you need to distinguish between cold and warm, and the fire is appropriate, if it is half a point of heat, or the slightest weakness, it can only fall short, and Dan's dream will come to naught. In short, controlling the heat is the simplest and most difficult part of alchemy, and if it is slightly biased, it will fail in alchemy, and at worst, it will destroy people. ”

Yang Qi immediately remembered it in his heart, and he didn't dare to forget it easily, and continued to bet on Bai Zisu's alchemy method. I saw that at this time, the flames in the bronze Dan furnace were sometimes vigorous, sometimes weak, and the two alternated, repeatedly, and there were more than 300 times back and forth. Bai Zisu said: "Each time has its own heat, so it is necessary to change the corresponding temperature on the basis of understanding the heat at each level, and in this process, it should be controlled freely and not biased." This requires us to practice daily reciprocating in order to achieve that practice makes perfect. ”

Yang Qi nodded lightly, his eyes did not depart from Bai Zisu's alchemy scene from beginning to end, and he devoted himself to the subtleties and insight into the subtleties. Suddenly, Yang Qi was taken aback and asked, "Master, why is there five layers of flame temperature in the Bronze Dan Furnace, and there is only one kind of fire recognition, why can it emit five different temperatures?"

Bai Zisu had a smile on his face, his expression was relieved, and he thought that he was worthy of being a person with the talent of Nine Patterns Divine Sense, and it was indeed unattainable for ordinary people. He smiled and said, "Xiao Yangzi, what you said is right, there are indeed five kinds of temperature differences between strength and weakness in the bronze Dan furnace, just because the five flavors of medicinal materials are being refined in the Dan furnace." The temperature that each herb can withstand varies and can turn to ashes if it is not done properly. Therefore, the five flames with different temperatures that you are sensing now are exactly the changes that the old man has changed in order to adapt to the five different medicinal herbs. ”

When Yang Qi heard this, he was shocked, he couldn't imagine that alchemy was so exquisite, and if he wanted to understand that each medicinal material could withstand the temperature, it was really ten years of grinding a sword. From the beginning of the selection of materials and the subsequent control of the fire, it is extremely difficult, especially the ever-changing fire, which is even more prohibitive. At this moment, Yang Qi finally understood why the Heavenly Master had such a respected status, but there were still very few, in addition to his own talent, what was even more embarrassing was this uncontrollable fire.

Two hours later, Bai Zisu said again: "Now is the most important moment for alchemy, which is Ning Dan. At this time, the essence of the medicinal materials in the Dan furnace has all melted, and what the Heavenly Master needs to do is to condense the essence into a Dan with the knowledge of fire, and break out of the furnace to become a treasure pill. You don't have to think that what the old man said is light, but it is a hundred times more difficult to operate in practice, and if there is a mistake, it will fall short and cannot be recovered. The hardships can only be experienced when you refine them yourself later. ”

Yang Qi was an eye-opener today, Bai Zisu and other celestial masters of the same level, how valuable the experience he personally imparted, he couldn't help but secretly rejoice that he could get the guidance of a famous teacher. As Bai Zisu said, if there is no famous teacher to teach, even if you have ten divine sense talents, it is difficult to achieve success. The intricate alchemy process just now is the priceless effort of countless predecessors, and it is by no means something that can be explored overnight.

Within a long time, bursts of Dan incense came from the bronze Dan furnace, refreshing people's hearts. Yang Qi was curious, and he looked at the furnace with the danxiang, only to see that there was a golden pill hanging inside, and there was a burning fire under it, which was a second-grade pure Yuan Dan. Bai Zisu said: "Today you are the first glimpse of the door, and it doesn't matter much. What Shicai told you is the general context of alchemy, and it is easy to say, but it is very difficult to do, if you want to improve your own strength, you can only do it yourself. ”

Yang nodded and said: "The teachings of the master are easy for the disciples not to forget. "For some reason, at this moment, I had the idea of trying it myself. The whole process of alchemy of Bai Zisu can be said to be beautiful, chic and free, and it is very yearning.

Immediately after, Bai Zisu began to refine the remaining four medicinal materials, all of which were smooth and smooth, and there were no mistakes, and all of them could be successfully refined, but Bai Zisu had a calm look on his face. It's not surprising that Bai Zisu's alchemy technique is unmatched in the world, and although the pure Yuan Dan has amazing effects, it is always a second-grade pill no matter what, and if it fails, it will inevitably lose its identity.

Bai Zisu handed over the five Pure Yuan Pills to Yang Qi and said, "The Pure Yuan Pill can only be taken three in a lifetime, and it will be useless to take it again." It is imperative that you refine in time, without delay, only with strength can you be able to fight vertically and horizontally. As for the other two, don't act rashly, the old man has his own plans. As he spoke, a hint of cunning appeared in his eyes.
