The Qiankun Dan Furnace can be stored in the body like a true spirit weapon, and it can be big or small, although this is a great thing, but this Qiankun Dan Furnace is a thing of the Alchemy Guild, and it does not belong to Ye Cenyu.

Ye Cenyu couldn't help but fall into a dilemma.

Due to the particularity of the Danhuo, the entire Ethereal Academy could not find an alchemy furnace suitable for him at all. And long-term possession of the Qiankun Dan furnace may not be a long-term method.

Ye Cen Yu thought about it for a while, and then he was relieved again.

Gu Shanmo lent the Qiankun Dan Furnace to Ye Cenyu, the purpose was obvious, he wanted Ye Cenyu to participate in the alchemy conference on behalf of the Miao Academy. As long as Ye Cen Yu gets the first place in the alchemy conference, this Qiankun Dan furnace can naturally continue to be used for a hundred years. This cycle repeats, and the Qiankun Dan furnace is not much different from Ye Cenyu.

However, the premise is that you must beat the crowd at the alchemy conference and get the first place.

The once-in-a-century alchemy competition, there are still twenty years, and it is unknown whether Ye Cenyu can survive for twenty years.

When it was night, no one disturbed it, and there was silence all around, which was a good time for alchemy.

Ye Cenyu retracted his thoughts and smiled self-deprecatingly: "Hehe, who can tell the future, grasping the present is the king." ”

He restored the Qiankun Dan furnace to its original size. Take out the alchemy materials from the jade wrench finger and prepare to refine the pill.

The first alchemy, for Ye Cenyu, can be described as inexperienced. So he chose the Hidden Elixir that was relatively easy to refine.

There are a total of 31 kinds of medicinal materials needed for the hidden elixir, of which 30 are relatively common medicinal materials, which can be purchased from Huaran Yishengtang.

The relatively precious material is the Hidden Spirit Grass, which is much more expensive than other materials.

A total of 500,000 Xuanjing was spent on the medicinal materials needed for a concealment elixir. Ye Cen Yu purchased ten materials.

According to the market price, the normal price of a hidden elixir is 600,000, and if it is successfully refined, it will be profitable and not lost.

The power of refining the Hidden Spirit Pill is 50%, and after the success rate of the Qiankun Dan Furnace is increased by 50%, the success rate of the Hidden Spirit Pill can reach 100%.

However, for an alchemist, there must not be a trace of deviation from the control of the heat of the Danhuo to the order of putting the medicinal materials, and if he is not careful, even if the pill has a 100% success rate, it will be ruined.

Ye Cenyu sorted and arranged the medicinal materials neatly, and then sat down cross-legged in front of the Qiankun Dan furnace, and went through the hidden elixir formula in his mind.

"Let's get started, whether it's successful or not, this first step must be taken!"

Ye Cen Yu slowly breathed a sigh of relief, his palms were stretched out relative to his chest, and he began to recite the Danhuo Technique silently in his heart.

Under the guidance of the Dan Huo Jue, from the palms of Ye Cenyu's palms, two streams of misty spiritual power that could be discerned by the naked eye floated out, intersecting between the palms, and slowly condensed into a ball of four-colored Dan fire, and with the injection of spiritual power, the Dan fireball became bigger and bigger. When the four-colored Dan fire was the size of a fist, Ye Cen Yu raised his hand and pointed towards the fire port of the Qiankun Dan furnace.

"Go!"

The four-colored pill fireball slowly floated into the furnace of the Qiankun Dan furnace.

"Boom!"

Dan fire burned violently in the hearth.

An ordinary Dan fire condensed by a Dan fire recipe can burn for half an hour, and the alchemist must always remember the time and supply the Dan Huo in advance, otherwise once the Dan Fire is extinguished halfway, he will have to start from the beginning.

The time for refining the elixir generally takes about twelve hours, which means that it needs to be replenished twenty-four times of the elixir. And the time it takes for the Divine Pill to be refined is 7749 days! For a full 588 hours, 1,176 times of Dan Fire is required!

This is just the basis of alchemy!

And the key to alchemy is the order and interval of the materials!

Alchemy materials are put in very strict order due to different melting points, generally the higher melting point is put in first, and then the alchemy materials with low melting point are put in, and finally all the materials are melted at the same time and condensed into Dan mud.

Dan mud is constantly quenched by Danhuo to remove impurities and slowly condense into Dan embryos.

The Dan embryo is the most important thing, once condensed, it will absorb the aura independently. If there are no accidents, the pill is considered to be 90% successful.

In the entire alchemy process, the spirit of the alchemist must be highly concentrated, and the refining of the pill should be observed at all times, and there should be no slackness. Not to mention drinking water and eating, even if you move, there is a danger that all your efforts will be lost.

According to legend, when the Enlightenment Divine Pill obtained by the beast god Xiang Yu was successfully refined, the alchemy master who refined the Divine Pill was exhausted on the spot, spraying blood and dying!

It can be seen that alchemy not only tests the alchemist's skills, but also tests the strength of his heart.

There are a total of seven processes in the order in which the concealed spirit pill materials refined by Ye Cen Yu are put in, among which the concealed spirit grass is put in first, and then every five herbs are put in at the same time, with the longest interval of one and a half hours, and the shortest interval is less than a quarter of an hour.

Ye Cen Yu used his mental power to slowly hold up the hidden spirit grass and slowly floated towards the inlet of the Dan furnace.

Under the roasting of the Dan fire, the moisture of the hidden spirit grass quickly evaporated and shrank. In less than half an hour, it slowly began to melt!

"That's not right!"

Ye Cen Yu frowned, according to the recipe, it took two hours for the Hidden Spirit Grass to melt, why did it only take half an hour for it to melt!

At this time, Ye Cengyu couldn't figure out the timing of the second step of putting in the medicinal materials, if he put the medicinal materials again, it would only increase the consumption, and it would no longer make any sense.

Ye Cen Yu stood up, held his chin, and walked back and forth around the Qiankun Dan Furnace.

"My dear, evil sect, how could it melt so quickly?"

Ye Cen Yu wandered around for a long time, not only did he not solve the mystery of the rapid melting of the hidden spirit grass, but he also discovered an even more strange situation:

Generally, under the baking of the Dan fire, the temperature of the Dan furnace wall gradually rises, and the heat around the Dan furnace is unstoppable, and some Dan furnaces even need an assistant to manually cool down.

Ye Cen Yu was surprised to find that the inside of the Qiankun Dan Furnace was burned by the four-colored Dan Fire, the inner wall was red, but the outer wall did not have a trace of hot feeling, and half an hour had passed, and the Dan Fire did not show the slightest sign of extinguishing.

Ye Cen Yu stopped and tentatively touched his palm on the surface of the Qiankun Dan furnace.

There was no burning sensation on the outer wall of the Qiankun Dan furnace, and there was not even a change in temperature rise.

Ye Cenyu's mind was racing, his eyes lit up, and he smiled.

"Hehe, it deserves to be the first Dan furnace in the Purple Spirit Continent, and it is really extraordinary. ”

Since the heat insulation effect of the Qiankun Dan furnace is so good, it means that the energy will not be consumed needlessly, thus prolonging the burning time of the Dan fire in disguise!

This not only saved the alchemist a lot of spiritual power, but also reduced the number of times the Dan Fire was replenished.

At this time, the Hidden Spirit Grass had already melted into a liquid state, suspended in the refining area like a small droplet, and the cyan surface shone with a leisurely cold light.

As time passed, the Hidden Spirit Grass grew smaller and smaller until it disappeared without a trace. And the Dan fire was slowly extinguished.

Ye Cen Yu had been using his spiritual sense to observe the changes in this Qiankun Dan Furnace, and he was pleased to find that his Origin Dan Fire had been burning for an hour, which was twice as long as that of ordinary alchemists!

"I see. ”

Ye Cenyu smiled and nodded. In his heart, he already knew the secret of the early melting of the hidden spirit grass.

Because the temperature of his four-colored pill fire was much higher than that of ordinary alchemists, it caused the hidden spirit grass to enter the melting stage ahead of schedule.

Although the first alchemy ended in failure, Ye Cenyu knew that his special ability was different from that of ordinary alchemists.

Now, if you follow the original recipe of the Hidden Elixir, I am afraid that you will not be able to successfully refine it. Ye Cen Yu re-modified the formula of the Concealment Spirit Pill, shortening all the time to a quarter compared to the Concealment Spirit Grass.

Refining again, Ye Cen Yu can be said to be familiar with the road, and it only took three hours to successfully refine the hidden elixir. And it's a hidden elixir with a superb attribute! The mysterious attribute attached to it is actually a multiplication of the concealment time.

The ordinary Concealed Spirit Pill can only be concealed and cultivated for half a month, while the Hidden Spirit Pill refined by Ye Cen Yu can last for a month.

Looking at the rounded hidden elixir in his hand that exuded a radiant streamer, Ye Cenyu was very happy in his heart.

"I've finally become an alchemist. ”

Ye Cenyu smiled and put the hidden elixir into the jade bottle that had been prepared a long time ago, and began to try the more difficult alchemy technique - refining several pills at the same time!

The alchemy furnace space can fully withstand the refining of several pills, but few alchemists try to refine several pills at the same time.

Because multiple pills are refined at the same time, ordinary alchemists will inevitably take care of one or the other, and they will not be able to take care of the other at the same time, and once they fail, they will have to suffer huge economic losses.

What's more, alchemists are all cultivators and have a long life, so it can be said that the most important thing is time. The Divine Pill is only forty-nine days old. There is no way to risk refining a few pills.

However, what Ye Cen Yu lacks now is time!

The success rate of the Ascending Spirit Pill and the Dream Divine Pill was too low, and Ye Cenyu had to find another way to increase the success rate of the two pills.

The Qiankun Dan Furnace can grow indefinitely, and the space for refining pills will also expand, if Ye Cen Yu masters ten thousand pills and refining them at the same time, then the most constrained success rate will be solved.

Just kidding, the Psychic Cave Mansion can provide unlimited resources!

"Hehe, if the uncle masters tens of thousands of pills and refines them at the same time, wouldn't it be a god pill!"

Ye Cenyu's eyebrows fluttered with lust.

Before the Qiankun Dan Furnace grows up, it can withstand the refining of ten pills at the same time. And there is no need to increase the intensity of the Danhuo.

Ye Cenyu's anti-heaven primordial god fully demonstrated the effect of reversing the sky in refining the elixir.

He refined eight pills together, and he didn't feel any discomfort at all.

From the control of the heat, the order and interval of the herbs, it is easy to master.

Three hours later, none of the eight Hidden Spirit Pills failed, and all of them were successfully refined. Among them, the worst one is the medium-grade elixir, three are top-grade, and four are superb!

If Gu Shanmo knew that Ye Cen Yu was so alchemic, I am afraid that he would be scared to death. For alchemists like Gu Shanmo, what Ye Cen Yu easily organized was tantamount to an impossible task for them!

Ye Cenyu smiled and shook the jade bottle containing nine hidden elixirs in his hand and said with a smile.

"Hehe, Condensation, blessed are you. ”

The reason why Ye Cenyu chose the Hidden Elixir as an alchemy test sample, in addition to its high success rate, another reason was that Ye Cenyu wanted to send the Concealed Elixir to Condensation.

The most terrible killer in the world is the killer who hides his cultivation and makes you mistakenly think that he is an ordinary person!
