According to this standard, the number of second-level elixirs that Liu Yu can refine has already reached three types.

Moreover, the success rate is far beyond 30%, and he is truly a "senior alchemist".

Even if he is asked to refine the second-level top-quality elixir, he is very sure that the efficiency will reach 30%.

In this way, you are not far from the master of alchemy.

"Why do you think so much? I don't rely on alchemy to gain a foothold, I just need enough."

Shaking his head, Liu Yu smiled slightly, took out the jade bottle and put seven Red Yuan Pills into it.

Then the impurities in the cauldron were cleaned, the cauldron was re-ignited and preheated, and the refining of the next elixir began.

Excluding failures along the way, each refinement of the second-level elixir basically takes about an hour.

And Chi Yuan Dan is a second-level middle-grade elixir. Including the preparation time for cleaning the cauldron, it takes more than an hour.

When the ten spiritual herbs for refining the Red Yuan Dan were all consumed, nearly a day had passed.

Counting the first successful one, Liu Yu successfully refined three furnaces of Chiyuan Dan, with a success rate of over 30%.

A total of twenty-seven Chiyuan Pills were obtained, and the next two times yielded ten pills.

"Based on the current situation, once I get familiar with this pill, the success rate should soon be close to that of the Yangyuan Pill."

Thinking about this, Liu Yu felt relaxed for a while.

This feeling of increasing knowledge and strengthening strength is really good.

He stood up, cleaned the Xuanhuang Cauldron inside and out, put it into his storage bag, and left the alchemy room.

…

The foundation-building true fire consumes very little mana, and the mental strength and energy of the foundation-building monks are also extraordinary, which can be considered "extraordinary" level.

After refining alchemy continuously for a whole day, Liu Yu still didn't blush or breathed. She just felt a little tired, but not to the point where she needed sleep and rest.

One day passed, and the potency of the elixir I took yesterday was almost absorbed.

Even if some of the medicinal power is deposited as erysipelas, it can still be washed with "Canglang Spiritual Water", and now you can take the elixirs to practice again.

Liu Yu went straight to the practice room, ready to try the effect of this Chi Yuan Dan.

He sat cross-legged on the futon, gently closed his eyes, and slowly adjusted his state.

Gathering energy and concentrating one's mind, holding one's strength and guarding one's will, one gradually enters a state of forgetting both things and myself.

In this situation where things and I have forgotten both things, the restless and impetuous mood that was originally a little complacent due to the improvement of alchemy skills gradually calmed down and returned to the original state of being calm.

"Gulu~"

After adjusting his condition, Liu Yu opened his eyes, took out the jade bottle containing Chiyuan Dan, poured out one and swallowed it.

As soon as the elixir enters the stomach, its power quickly melts and takes effect, and part of it turns into wisps of pure fire-attribute spiritual energy.

This aura has the unique scorching heat and hotness of the fire attribute. It is very easy to be absorbed by monks who practice fire attribute skills, and can improve their cultivation to increase the upper limit of their mana.

Feeling the burning sensation in her belly, Liu Yu did not dare to be careless and immediately closed her eyes.

He hit the spells in his hand continuously, running the fifth level of Qingyang Gong, constantly absorbing the medicinal power of Chiyuan Dan, and refining wisps of pure fire spirit energy.

One weekly cycle, two weekly cycles.

These pure fire-based auras go through thirty-six great cycles before they are transformed into the mana of Qingyang Gong, and then flow into the Dantian.

It passes through the Qingyang Demonic Fire in the Dantian and removes some impurities before finally returning to the "Lake of Mana" at the bottom of the Dantian.

Liu Yu's complexion gradually turned green, and he kept running the Great Zhoutian Cycle, repeating this process, accumulating mana bit by bit.

"Huhu"

It was not until three hours later that I completed this meditation practice and finally opened my eyes.

"It doesn't seem to be as effective as recorded?"

"It's only a little more than 20% better than the Yangyuan Pill."

He frowned slightly, holding his chin and thinking carefully.

"Is there a mistake in any step of the alchemy process?"

"Is this causing the drug to become less effective?"

Liu Yu recalled the recipe of Chiyuan Dan in detail, and recalled his own alchemy process, constantly making comparisons.

However, after comparing several times, we still came to the conclusion that there is no difference.

Then he poured out all the elixirs he had refined this time and compared them repeatedly, but found no difference.

"What is the reason?"

Liu Yu rinsed her body, put on a new robe, and sat in the hall, still thinking about this problem.

"Could it be the reason for the skill?"

After ruling out every possibility, he finally thought of this, and then the more he thought about it, the more likely it became.

The specific grade of Qing Yang Kung is unknown, but it is at least a top grade Kung Fu.

The purity of mana is very high from the beginning. Every ray of mana during the foundation building period has to go through thirty-six great cycles.

Then it has to be initially tempered by the demonic fire before finally entering the lake of mana.

After reading several books of different levels of exercises in his hand, Liu Yu understood.

Ordinary exercises only need to go through twenty-four great celestial cycles to refine mana, and the meridians running through them are far less complex than Qingyang exercises.

Even the top-grade technique, Netherworld Xuan Bing Lu, only needs to go through thirty cycles of the Great Zhoutian. The movement of the meridians is a bit more complicated, but it is not as good as Qingyang Kung Fu.

There is no doubt that the more the Great Zhoutian cycle is carried out, the purer the mana will be in the end.

From this point of view, even if it is a top-grade Kung Fu, the purity of its power is not as good as that of Qingyang Kung Fu, just a little bit different.

What's more, there is "Demon Fire Refining Yuan" at the end.

The higher the purity of mana, the more spiritual energy is required for transformation.

From this explanation, it seems possible to explain why the effect of Chiyuan Dan is not as good as expected.

"Perhaps, it is precisely because of the technique and the purity of the magic power."

Thinking about this, Liu Yu felt a little relieved.

However, even though he was already very confident, he still decided that if he had the opportunity, he would ask Master Yibao for advice, or go to the sect's library to check it out.

"Is Qingyang Kung really just a top-grade Kung Fu?"

"What kind of skill is it? Where can I find the remaining parts?"

The old questions have not gone away, but new ones have arisen.

The more Liu Yu practices, the more extraordinary he can feel the Qingyang Kung.

Whether it is the extremely high purity of mana from the beginning or the great potential of the Qingyang Demonic Fire, both are extraordinary techniques.

He had seen the "Three Heroes and Four Heroes" and the "Six Sons of Hehuan" take action, but judging from their judgment between actions, the skills they practiced were no more than this.

If he reaches the late stage of foundation building and undergoes the seventh demonic fire refining, his own strength will be no different.

Not to mention the secret technique of "Demon Fire Refining Elements", which can not only increase your strength, but also increase the chance of forming a pill.

All kinds of performances are enough to show that the Qingyang Kung is extraordinary and gives Liu Yu a strength that far exceeds that of monks of the same level.

Coupled with sophisticated magic weapons and spiritual weapons, it can even compete with later monks in the early stages of foundation building.

"Could it be a top-level skill?"

"A top-level skill comparable to the sect's inherited skill "Three Yang Burning Heaven Skill"?"

Liu Yu thought a little excitedly.

But after thinking for a while, there was no result, so I had to give up.

The disciple of the Hehuan Sect back then was dead. Even if he wanted to trace the origin of the bronze lamp, he would have no way to start.

What's more, his hand can't reach the Hehuan Gate.

After taking out the bronze lamp and playing with it for a while, Liu Yu put it back into the storage bag, took out a book of spiritual herbs and started to read through it.

…

The main force attacks the large gathering points of immortal cultivators and sends small teams to conquer the small forces along the way. This method is not only adopted by Yuanyang Sect.

The Hehuanmen and Qingxu faction who attacked Youzhou together also adopted the same method.

Sending out teams similar to the "Qingfeng" teams scattered throughout Youzhou to fight for the interests of the sect, there is also a vague intention of initially racing to enclose the territory.

Due to the unexpected results and the fact that most of the team leaders are very strong, many teams have made good progress in just one day after leaving the Ancient Que Immortal City.

Some are slower than Liu Yu, and some are faster than Liu Yu.

For example, senior sister Li Buyu is not only strong in her own right, but also backed by her family.

The lineup configuration of his team was far from comparable to Liu Yu's. At this time, there was no need for any strategy at all, and they were able to defeat each other in just two days.
