After several setbacks, Xu Yi believed what the alchemy notes said: One way of alchemy, one elixir, and all methods, if you don’t enter this gate, you will be justified, just like a blind man touching an elephant.

Alchemy is a very mysterious thing. If you cannot enter the profound stage, you cannot be considered as an entry. If you do not enter the door, you cannot communicate with each other's principles.

To put it bluntly, just reading some classics and experimenting does not mean getting started.

Because the medicinal properties of medicinal materials are too complicated, such as the prescription of Yuandan, the main medicinal properties of the three herbs are very clear, but they must also have miscellaneous properties. Specifically for the same herb, different soils and years, different miscellaneous properties will be destined to be different. Often, this microscopic difference can determine the success or failure of the auxiliary agent.

In addition, everyone's alchemy techniques are different from the microscope, so the same medicinal materials are often different from the finished products refined by different people.

To put it simply, alchemy is not produced through assembly line. The same raw materials and production equipment can be produced by any skilled worker.

It is precisely because of various microscopic differences that a threshold for entry is formed.

It is precisely because of the microscopic differences that a single alchemy method is formed. The so-called all methods are not the difference between the alchemy formula, but the difference between the alchemists.

For example, when refining Yuan Dan, the pill recipe has never been the most important thing.

The most important thing is the elixir rate. The elixir rate is guaranteed, which proves that an alchemist can control microscopic differentiation relatively stably.

Why did the people in the Gongxue Society clearly refined Yuan Dan but did not receive the respect they deserved and were not treated differently by the senior officials of Xuanqing Sect?

Because everyone knows that even if the alchemist below the spiritual root has refined the Yuan Dan, it is because of accident.

This kind of accident is extremely difficult to replicate.

It is difficult for monks below the spiritual root to have the strength to stably control microscopic differentiation.

After saying this, the entry threshold for alchemy is to understand this microscopic differentiation. Otherwise, no matter how much experience you have, no matter how many experiments you have, it will be difficult to achieve real results.

This microscopic differentiation varies from person to person and is difficult for others to teach.

Only by crossing this threshold can one be considered a real entry and can one conduct effective exchanges on alchemy theory with other alchemists.

Otherwise, how can someone who is still memorizing the multiplication formula be mixed into someone’s discussion on calculus and linear algebra?

At that time, although Xu Yi had heard of the principles of alchemy in this area, he was not as good as practicing and comprehension himself.

He now understood that no one could help him with this level, but he was the only one who could pass it himself. As for whether he could pass it through, he had no idea.

This is a completely enlightenment process. If you realize it, you will realize it. If you don’t realize it, you will not realize it. Maybe it will be broken in ten days, or maybe it will not be solved for ten years.

Gradually, passing the threshold of alchemy became Xu Yi's obsession, and he practiced alchemy all day long without any trouble.

For this reason, he even spent 200 Yuan Dan to purchase a monthly service for Earth Fire.

Soon, the first dose of the drug was bottomed out, and the second dose consumed more than half of it. Xu Yi never touched the shadow of the molded auxiliary agent.

"Uncle Hu Zi, what are you doing? I haven't seen you for many days."

On this day, Xu Yi was in seclusion on the seventh day of the alchemy refining, Qiuwa broke in and said dissatisfied.

In the past, although Xu Yi was practicing elixirs, he still remembered taking time to accompany her. Now that he has been obsessed with his whole life, he seems to be a demon.

At this moment, Qiuwa was startled when she saw Xu Yi. If Xu Yi had not seen her eyes still gentle, Qiuwa would have screamed.

Xu Yi in front of him had a pale face, thin bones, a large beard and hair, dirty and messy, all tied and furry.

Xu Yi waved at her and said, "Uncle Hu Zi is refining elixirs. Go and play. After a while, Uncle Hu Zi breaks through and comes to find you."

After saying that, he focused on the changes in the green stove again.

Although Qiuwa loved to play, she knew the importance of it. Seeing Xu Yi's appearance, she knew that the matter was very serious, so she stopped urging her. However, she felt that the green stove was burning brightly in the fire, which was very beautiful and interesting, so she stood quietly by the side, just to watch the fun.

In a blink of an eye, another hour passed, Qiuwa's little brows became higher and higher, because his omnipotent uncle Beard failed three times.

"No, Uncle Hu Zi, no, the airflow in the west cannot flow, and cannot be mixed with the airflow in the east, otherwise..."

Qiuwa suddenly spoke. Before he finished speaking, a burnt air came. The green furnace light flashed, and the burnt air immediately dissipated. A ball of waste was thrown into the ground fire at the base of the alchemy furnace and burned all over.

Xu Yi was stunned. After more than ten breaths, he turned his head and stared at Qiu Wa, his eyes a little scary. Qiu Wa let out a wow, and she was about to be scared to cry.

Xu Yi then realized, hurriedly hugged her and comforted her repeatedly.

Qiuwa stopped crying, wrinkled her nose and ignored Xu Yi. Suddenly, she covered her nose again, jumped out of Xu Yi's arms, and shouted, "It's so stinking, so stinking... Uncle Hu Zi must have not taken a shower for a long time..."

Xu Yi smiled awkwardly, "Okay, Uncle Hu Zi takes a shower immediately, take a shower immediately. But before that, you have to tell Uncle Hu Zi how did you know that the two airflows cannot be mixed together? Hurry up, tell Uncle Hu Zi."

Before Qiuwa finished speaking, the alchemy failed and Xu Yi never thought it was a coincidence.

Qiuwa smiled proudly, "What's so strange? I watched it four times, and you did this in the first three times, and then you failed. Can't they sum up their experience?"

Xu Yi stared at Qiu Wa in disbelief, "You said that my four operations were ruined at this point. What's going on?"

In Xu Yi's eyes, his operation was different every time, and his medicinal properties and spiritual energy were constantly changing.

But Qiuwa said this, which made him extremely surprised.

Qiuwa said, "Don't you want to blend the two fishy smells together? As a result, every time you refine the pure, miscellaneous air will invade. Every time you refine the two fishy smells, you will start to blend before the two fishy smells are pure. Once the impure surges, the two fishy smells gather together, and there will be a smell of mush in your stove."

The sound of Qiuwa's like a clear oriole is not understood by Xu Yi.

Seeing Xu Yi's face was confused, Qiuwa caught a black grass from the bamboo basket not far away. He waved his little hand and a solid halo appeared in his palm.

The next moment, the black-grown grass disappeared, replaced by spectra of different colors. Overall, the spectrum was divided into four, light cyan, dark green, thick lead color, and light variegated colors, and among them, light cyan, dark green, and thick lead color, there are also some locally mixed with variegated colors.
