Chu Yun did not bring any medicinal materials when he came out this time, but he had bought a lot of ordinary medicinal materials in the clinic before, so there was no problem in refining a furnace of Evil-Eliminated Pill.

He first found out the medicinal materials, then skillfully turned on the furnace and raised the fire...

The process of alchemy is a process of removing the drought and retention of fresh greens. First, useless things in the medicinal materials must be removed so that the elixir can be ensured.

During the alchemy process, ordinary alchemy furnaces do not need to consider the emission of useless things in the medicinal materials, everything is carried out naturally. However, ordinary alchemy furnaces cannot be thorough in eliminating waste or retaining essence. The reason is that there is no external interference.

But this Qiankun Furnace is different. It comes with a spirit gathering array. As long as the spirit gathering array is opened, no breath can be discharged, which is harmful and useless for alchemy.

Therefore, in the first half of the alchemy, the spirit gathering array must be operated in the reverse direction, and the useless things in the medicinal materials will be turned into waste gas and discharged. When the waste gas is discharged, the spirit gathering array will be operated in the direction to absorb the spiritual energy of heaven and earth, nourish the essence of the medicinal materials, so that the medicinal effect will be retained 100% and even greater effects will be achieved.

This is also the most fundamental reason why Chu Yun built this alchemy furnace.

Only by removing the drought and reserving the essence can we achieve the best elixir and achieve the highest elixir rate.

It can even be said that as long as there are no mistakes in the alchemy process, the elixir rate of elixir refined through Qiankun Furnace will be 100.

As the flame rises, the medicinal materials in the alchemy furnace begin to boil out the juice, and then melt and turn into a viscous liquid.

This is a very magical process. No matter which kind of medicinal material is, if it is placed outside and roasted with fire, it will only burn and eventually turn into ashes. However, in the alchemy furnace, the moisture of the medicinal material will not evaporate, and it is mixed with the medicinal material to form a juice. This is the best way to boil medicinal material.

The refining process is still continuing, and Chu Yun's fire control technique changes rapidly. At the same time, the internal force also enters the furnace through the alchemy furnace wall. Under the mixing and stirring of the internal force, the residue in the medicine juice turns into gas in a strange way, and actually dissipates out through the alchemy furnace wall.

"This is like an exhaust fan." It was not difficult for Chu Yun to refine the Evil-Eliminated Pill, and he still had the heart to make fun of him.

The originally turbid medicinal liquid gradually became green as the waste gas was discharged, like flawless jade.

In the past, Chu Yun refined the Evil Elimination Pill, which at most made the medicine liquid turn dark green. Now, this crystal clear green pole made Chu Yun very excited.

"Reverse the spirit gathering array!" Chu Yun quickly changed from a fire control technique to a formation control technique, and the operation of internal force also changed. The formation of the alchemy furnace finally returned to normal operation.

At this moment, Chu Yun felt that the aura around him changed, and a trace of spiritual energy gathered from all over the place, and then quickly poured into the wall of the alchemy furnace.

Chu Yun's control over the alchemy furnace was absolutely as if he was instructed by his arm. The slightest change in the alchemy furnace could not be concealed by Chu Yun's perception. He could clearly feel the spiritual energy entered the alchemy furnace and quickly merged into the medicine liquid.

The integration of spiritual energy into the medicinal liquid is not the effect of the formation, but a natural phenomenon during alchemy.

The fundamental reason why alchemy can exert medicinal effects that are several times or even dozens of times higher than medicinal materials themselves is to absorb the spiritual energy of heaven and earth. This absorption of spiritual energy of heaven and earth is achieved by relying on unique alchemy techniques, the guidance of internal forces and the natural attraction of different medicinal properties after mixing and refining.

When refining ordinary elixirs, the spiritual energy absorbed is very little, and most of them cannot be sensed, even level 8 and level 9 elixirs are the same.

But if you refine a level 10 pill, the spiritual energy it absorbs can even form a spiritual energy storm. You can imagine how powerful the level 10 pill is.

The spirit gathering array plays a role not only to absorb more spiritual energy, but also to eliminate the dissipation of medicine, allowing the medicine to absorb spiritual energy more thoroughly.

The refining of the Evil Elimination Pill is not difficult, especially for Chu Yun.

In less than a stick of incense, the refining of the Evil Pill is coming to an end.

At that last moment, Chu Yun immediately stopped the operation of the spirit gathering array and at the same time used the alchemy technique.

At this moment, the medicine liquid has absorbed enough spiritual energy and has shown a perfect state. If more spiritual energy pours in, it is likely to cause a elixir explosion when the elixir is condensed.

Blasting elixir is a result of uneven energy when refining elixirs. After the alchemy reached the level of Chu Yun, there was no case of blasting elixirs again.

As the elixirs were formed, Chu Yun sensed the changes in the alchemy furnace, and a smile appeared on the corner of his mouth.

"Puff..." A strange sound suddenly came from the alchemy furnace, and Chu Yun's face changed suddenly, and then he showed a bitter smile.

Chu Yun gathered up and opened the lid of the alchemy furnace. He saw five green pills lying quietly at the bottom of the alchemy furnace. Next to these five pills, there was a small pinch of black and gray dust.

"There is still a pill explosion. It seems that there are still some problems controlling the spirit gathering array just now." Chu Yun murmured.

However, Chu Yun was very satisfied with this result. Five pills of pills have proved that this Qiankun furnace can indeed greatly increase the pill generation rate.

You should know that even Chu Yun can ensure that each furnace of evil-elimination pill is successfully refined, the number of elixirs is only three, which is 50 elixirs. However, using an alchemy furnace has reached five, which is definitely a leap forward. If he could control the alchemy furnace more accurately just now, the alchemy rate could reach 100.

Chu Yun picked up a pill to eliminate evil and carefully looked at it.

In terms of quality, the Evil-Eliminated Pill I refine this time looks much better than the previous Evil-Eliminated Pill. Although it has been reduced a lot, the effect of the medicine is stronger. At the same time, there is no breath of the pill leaking out, which means that the quality of this pill is very perfect.

One advantage of this perfect pill is that it is stored for a long time without worrying about the loss of its efficacy.

Chu Yun is not sure if anyone can refine a perfect-quality elixir today, but it was difficult for him to refine such a quality elixir before.

After making this discovery, Chu Yun felt even more excited, but he became much more cautious.

"It's better to experiment a few more times first, and wait until you are 100% sure before you can refine the True Qi Yuan Pill." Chu Yun made the wisest decision.

Chu Yun then left the inn and went to the clinic again. When he came back this time, there were more medicinal materials in his hand.

In the next two days, Chu Yun kept refining elixirs. Although he had refined two or three levels of elixirs, he was already very familiar with this alchemy furnace after long-term refining. The most important thing is that his switching of alchemy and array control techniques has reached the point of perfection.

With this foundation, Chu Yun finally decided to start refining the True Qi Yuan Pill.

In order to ensure that everything is foolproof, Chu Yun locked the doors and windows of the room, and asked Xiaobai to guard the room outside, not allowing anyone to come in.

With Xiaobai's strength, Chu Yun believes that no one in this Yangzhou city can break through its obstacles.

Everything was ready, Chu Yun put the spirit-devouring fruit into the alchemy furnace and then began to raise fire and refine the alchemy.

The most troublesome medicinal materials of the True Qi Yuan Pill are the Spirit-Devouring Fruit. The strength of this thing is famous for, and it takes at least two hours to refine it.

It is definitely not something that ordinary alchemists can bear if they continue to refine the spirit-devouring fruit. What's more, refining the spirit-devouring fruit is only the beginning of the alchemy. It will take about two hours later to complete the refining.

As Chu Yun used his alchemy techniques one by one, the temperature in the alchemy furnace became higher and higher, while the spirit-devouring fruit was like a stubborn stone without any movement.

Chu Yun has enough patience and naturally will not feel any impatient.

An hour passed, and the Spirit-Devouring Fruit finally softened a little...

When it was almost two hours, the Spirit-Devouring Fruit completely softened and lay on the bottom of the alchemy furnace like a ball of jelly.

Chu Yun quickly unveiled the alchemy furnace, then put the twin golden yang grass, Hunyuan fruit and a deep-sea volcanic stone as big as a palm in it, and the remaining auxiliary medicines were added.

With the addition of these medicinal materials, the originally empty alchemy furnace was suddenly filled with most of it.

The flames continued to burn, and the medicinal materials inside began to melt under high temperatures, and slowly half of the furnace of medicine was gathered at the bottom of the furnace.

A trace of various aura emanated from the alchemy furnace and spread throughout the room. For a moment, the whole room emitted a fragrance of medicinal materials.

Chu Yun knew that the aura emitted was made of residues that had no use to the True Qi Yuan Pill.

Slowly, the medicine liquid at the bottom of the Dan Furnace began to decrease and gradually turned white, like milk...

When no breath evaporated from the alchemy furnace, Chu Yun instantly reversed the spirit gathering array to avoid the dissipation of effective medicine and absorb the spiritual energy of heaven and earth.

Although Chu Yun's internal strength was extremely strong, under this high-intensity alchemy, the internal strength still dissipated like flowing water.

His face was cold, his brain was rapidly moving, and his consciousness was highly concentrated, observing the slight changes in the alchemy furnace.

He dared not be careless at this moment. This furnace of elixir can be said to be related to his future destiny. Once he succeeds, his own and his own power will bring about a leap forward development.

Taking advantage of the moment of two alchemy techniques exchanged, Chu Yun quickly took out a pill that restored his internal strength and put it into his mouth, and then continued to devote himself to the great cause of alchemy.

Time passes slowly, and the medicinal liquid in the alchemy furnace gradually becomes viscous and dry, and the volume is gradually getting smaller.

"Swish..." A gust of wind hangs through Chu Yun's ears. This is not an ordinary wind, but a spiritual storm.

Chu Yun could even see light green whirlpools around the alchemy furnace, and they were all spiritual energy sweeping from all around.

Ordinary martial arts practitioners have very weak sense of spiritual energy. Only when their strength reaches the Three Flower Realm can they truly sense the spiritual energy in the air.

Although Chu Yun made a lot of noise, it is still unknown whether there are masters from the Three Flower Realm in Yangzhou City, so it is naturally impossible to notice the noise here.

The spiritual energy storm is getting stronger and stronger. Although the medicinal liquid in the alchemy furnace is drying up quickly, its volume has not decreased at all. The volatile water and spiritual energy are just offset... To be continued.
