Jiang Wuchen gathered around the elixir furnace, which was more than one person high. It was a triangular elixir furnace. The furnace body was engraved with runes. These runes were not complex. Jiang Wuchen recognized them at a glance and could add to the pill.

In the north of the alchemy furnace, the word "Xingjun" is engraved with seven stars below.

"Seven grade alchemy furnace!" Jiang Wuchen was surprised.

Xu Hai smiled and said, "I didn't expect you to know about the alchemy furnace. Do you understand alchemy?"

Jiang Wuchen said with a smile, "what kind of understanding is it?"

"Alchemy is a complicated project. You can learn it by simple introduction to alchemy, but you need to be proficient in refining high-quality pills. In my opinion, if you are proficient, you can call it understanding!" Xu Haidao.

Jiang Wuchen said, "in this way, I have a little knowledge. This alchemy furnace is good. It is said that alchemy furnaces with more than four grades should be controlled by the drug temple, isn't it?"

Xu Hai disdained a smile and said, "this is one of the means of the medicine temple to control high-grade pills. Strictly speaking, it is.

However, people who can refine high-grade pills will never be restricted by this rule, and those who are restricted usually have little background and influence. It is not easy to refine high-grade pills. Although the spirit of Yuan spirit has recovered, the medicinal materials for refining pills are decreasing day by day, especially the medicinal materials that can refine high-grade pills are becoming less and less. "

Jiang Wuchen said, "what is the high grade in your mouth?"

"At least three grades or more!" Xu Haidao.

"More than three products can be called high-grade?" Jiang Wuchen couldn't help thinking of the foundation building pill he refined.

Xu Hai nodded and said, "there was no such provision before, and it was almost put forward by several gates at the alchemy conference.

Do you know why it is fixed in the third grade? "

Jiang Wuchen shook his head and then said, "isn't it because of building Jidan?"

Xu Hai's eyes lit up and said with a smile, "that's right!" then he looked at Jiang Wuchen with meaningful eyes and said, "I'm more and more curious. Who is your first teacher? You can know this, but you can't know it from birth. Someone must have told you. Don't hide it. Tell me?"

Jiang Wuchen laughed and said casually, "it's from a dream."

Xu Hai shook his head reluctantly and said, "if you don't want to say it, forget it! About a hundred years ago, with the weakening of the spirit of the Yuan Dynasty, when it became very difficult for practitioners to become a spirit, practice became extremely precious.

In practice, Qi refining is the main way and pill is an auxiliary means. However, when the road of Qi refining begins to fail, pill has become an equally important means in parallel with Qi refining.

Therefore, since then, some people have proposed to restrict the pill. Although the pill can be regenerated, the various medicinal materials and materials used to refine the pill are non renewable.

Although those precious medicinal materials that often take thousands of years to form can reappear after thousands of years of growth, who can live more than a thousand years for today's practitioners?

So these resources are equivalent to non renewable.

Alchemy is an extremely waste of resources, because resources alone may not be able to refine pills, which has a great relationship with alchemists, alchemy furnaces, alchemy prescriptions and alchemy skills.

The same resource falls into the hands of a low-level alchemist and a high-level alchemist. Even if it is refining the same pill, the success rate is different.

If the refining of this resource is successful, it's OK. If the refining fails, it is equivalent to nothing and a pure waste of resources.

Because of the depletion of Yuan spirit, resources become more and more precious. Coupled with the confusion of alchemy in the practice industry, the medicine Temple invited Kunlun palace, Piaomiao palace and Qizong to hold several alchemy conferences, so as to share alchemy formulas, and then discuss how to control alchemy.

In this context, the above control measures for the four product alchemy furnace were put forward. In fact, at the beginning, the drug temple was eager to manage all alchemy furnaces, even one product.

But later, it was found that the number was too large to manage. The Kunlun Palace also opposed his behavior. If the Kunlun palace did not agree, the medicine temple would have no right to speak.

After several discussions, it was finally fixed on the fourth product. The fourth product alchemy furnace can refine three products and below. Among the three products, the most landmark for practitioners is building foundation pills!

The foundation building pill was once the most popular pill refined by various sects, because once taken, practitioners can respect teachers and greatly improve the strength of sects.

There was a time when a large number of low-level practitioners appeared in the spiritual world because of building Jidan.

But later, with the increasing shortage of resources, it was found that the medicinal materials needed for refining zhujidan can be used to refine other high-grade medicinal materials.

The number of low-level practitioners is huge, and building Jidan is a waste.

Later, Qinghe, President of the Kunlun palace Muling academy, put forward his view that "there is no need for junior practitioners to take pills, especially those with ordinary talents.

Dan medicine can be quickly completed to improve the strength of practitioners in extreme time. However, because of the rapid completion, practitioners will not feel the loneliness and difficulties in practice, and will think that it is easy to practice.

Practice is an act against heaven. You can respect the teacher by taking the foundation building pill step by step. Then what? They are eager to continue taking pills and use pills to improve their cultivation, rather than relying on their own efforts and their induction to heaven, things and nature.

This is contrary to the original intention of practice! "

This view has been supported by many people, especially the medicine temple. Since then, the number of building Jidan has become less and less. The disciples at the bottom have a hard time and complain.

However, so far, President Qinghe's view is completely correct. Because there were few practitioners who really became the strongest because they took the building foundation pill more than 100 years ago.

Including Vice President Feng Luyao, they improved their accomplishments completely by relying on their talents and their own abilities, and cultivated strong patience and perseverance from the beginning.

These two points are not possessed by those practitioners. "

"Oh, I see." Jiang Wuchen took a long breath and couldn't help sighing: "the journey of cultivation is much more complex than I thought. This field is no less than any industry in the world, and even more complex and difficult to control."

"The practice world is the place that can best reflect human nature. People can't see it. When practice becomes obsession, it can do anything. It's like more than ten years ago, the tall practice world destroyed the soul sect for the so-called soul cultivation.

What if it's a famous sect and a large one? It's nothing to kill a sect in order to get certain benefits! Even they don't have the slightest sense of guilt. "Xu Hai sighed.
