Yun Yueyao stood aside quietly, and stepped forward to help when Chen Lao commanded, everything was done thoughtfully and moderately, and Chen Lao was very satisfied.

When Elder Chen was refining this furnace of elixir, Yun Yueyao watched carefully.

Before coming, when preparing the medicinal materials, Chen Lao mentioned that the name of this furnace pill was Conglong Dan, although Yun Yueyao had not refined this flavor pill, she had done enough preparations.

This elixir is recorded in the new codex left by the ancestor, but the codex of the ancestor is not known how many years it has been placed. There is no record of the lotus pattern of the Taoist platform in the records on it.

But fortunately, the medicinal materials in it did not change much, and Yun Yueyao used the period before the alchemy conference to practice how to refine it in the hairpin space.

She didn't use the previous ancient method to refine, but tried to use the latest method described by Chen Lao. At the beginning, it was not satisfactory, but fortunately, the most important thing in the space was the medicinal materials such as Linghua Lingcao.

Yun Yueyao tried refining hundreds of times, and finally increased the success rate, ensuring that all the high-grade pills that came out every time were high-grade pills.

From Longdan to one furnace and two, the quantity is fixed, and what needs to be pursued is not quantity but quality.

The higher the level of the elixir, the more difficult it is to refine, the lower the success rate, and the more stable the quantity.

The Liupin Cong Long Pill is the elixir used in the Transformation Period, and its effect is to assist the Transformation Cultivators to break through the bottleneck. The name of this Dan is taken from the meaning of the dragon's work.

Yun Yueyao was not satisfied with only refining a top-grade elixir.

After refining the top-grade elixir, she cultivated a large number of medicinal materials and continued to practice to improve the success rate and quality.

In the hairpin space, for more than a thousand days, Yun Yueyao fixed two furnaces every day, and meditated to recover after practicing.

It wasn't until the last furnace of the last day that she was finally able to stably refine the best from the Dragon Pill.

It's just that the success rate is not high, about fifty percent, that is, one furnace is successful every two furnaces, and the other furnace is only a little better than the high-grade pill.

With such quality and such a success rate, Yun Yueyao is not particularly satisfied.

However, if this is known to others, probably the eyeballs will pop out.

Looking at the fifth-level cultivation realm in the immortal spirit realm, one is counted as one, and all the Dan masters are counted, and they can't find a single one who is so perverted by Cheng Dan.

The top Dan Master, refining the best elixir, the success rate is about the probability of one furnace succeeding in ten furnaces. Even if King Dan makes a move, he can probably only guarantee the success of one of the eight furnaces.

But Yun Yueyao's requirements for herself are at least eighty or ninety percent of the success rate.

And the Heavenly Peerless Dao people also have an attitude of approval towards this.

His requirements for Dan Dao and Kendo are very harsh. Therefore, Yun Yueyao, who was taught by him, has always been very strict with herself.

Maybe this is a famous teacher and a high apprentice, right?

Right now, watching Chen Lao refine it with her own eyes, Yun Yueyao found out from it that her own methods were different from those of Cheng Lao.

I also learned a lot.

The techniques she knows, for today's Dan masters, are all alchemy techniques that can only be used by ancient monks.

It is very different from the current alchemy method.

Yun Yueyao didn't want to show her feet in these small details, so she studied very seriously.

Now is not the time for her to be exposed, since she is not strong enough, then hold on. It doesn't matter if you pretend to be a pig and eat a tiger, or if you are obscure. There's always nothing wrong with developing in secret.

Yun Yueyao's serious study attitude made Chen Lao, who had been refining pills seriously, very satisfied, and the more he came into contact with Yun Yueyao, the more he liked such a student.
