"Doesn't it look simple?" Liu Lao suddenly looked at Chu Yi with a smile on his face.

Chu Yi nodded a little hesitantly, in his opinion, although the alchemy process that Liu Lao had just now was relatively cumbersome, it was still quite simple.

"Then next, you refine this elixir once, and I'll watch from the sidelines. ”

After Liu Lao said that, he took out a copy of his storage ring, the same elixir and medicinal materials as before, and put it aside.

Chu Yi came to the Dan furnace with some eagerness, first the warm furnace......

Chu Yi opened his right hand, and a cluster of flames turned by spiritual power appeared on it. Chu Yi carefully placed the spiritual fire under the Dan furnace and began the first step of alchemy.

After about a quarter of an hour or so, Chu Yi felt that the furnace at this time should have been almost warm.

He took out a spirit grass from the side, threw it into the Dan furnace, and then began to control the spiritual power, carefully refining.

At the beginning of refining, Chu Yi was still a little nervous, but after a while, Chu Yi relaxed a little.

Chu Yi was a little proud in his heart, and suddenly, the Huiling Grass in the Dan Furnace, which had not yet been successfully refined, instantly turned into ashes.

Chu Yi looked at the ashes of the spirit grass in the Dan furnace with a confused expression, his heart was full of disbelief, his control just now obviously didn't go wrong, how could it fail directly?

But fortunately, he had a master, Chu Yi looked at Liu Lao with a look of help, "Master, what's going on? ”

Seeing this, Liu Lao laughed, "Why, doesn't it look very simple? Let me tell you, there are many ways to make alchemy." ”

Chu Yi honestly stood aside and nodded again and again, he was really a little arrogant, this was a little different from him.

"That's because your cultivation has been too smooth recently, and you haven't experienced some tempering, if you are still like this, it would be wishful thinking to break through to the eighth layer of Qi cultivation before the Great Comparison of the Sects. ”

At this time, the voice of the old man suddenly appeared in Chu Yi's mind.

Chu Yi was stunned for a moment, yes, his recent cultivation was indeed a little too smooth, whether it was breaking through the late stage of Qi training, or cultivating into the second layer of the Glacier Prison Snow Storm.

It can be said that there is no danger, which makes him a smooth success, and it is precisely in this way that he thinks that he must be able to refine the pill very easily.

"How do I temper to break through to the eighth layer of Qi cultivation before the Great Competition of the Sects?" Chu Yi said silently in his heart.

"Take the mission of your sect, and then borrow this experience to go to the nearby Demon Beast Mountain Range and start hunting demon beasts. The indifferent voice of the old man sounded in Chu Yi's heart.

At this time, Liu Lao spoke again, "You think about the steps you just made, what went wrong?"

Chu Yi was stunned when he heard this, what went wrong?

......

"Could it be that when I warmed the furnace, there was some problem?" Chu Yi said with some hesitation.

In addition to the problems that may occur when the furnace is warmed, there will only be problems when refining the spirit grass. However, he carefully recalled that when he refined the Spirit Grass, there were indeed no problems.

Liu Lao smiled and nodded, "That's right, it was when you warmed the furnace that there was a problem." When you warmed the furnace just now, the temperature in the furnace was not balanced. ”

"That's why when you refine the elixir, the temperature of the elixir varies from place to place, which causes the elixir to turn directly into ashes. ”

Chu Yi nodded, I see, I didn't expect a simple warm furnace to be so exquisite, and after the Dan furnace cooled down, Chu Yi started a new round of alchemy.

However, this time, Chu Yi was much more careful than before, and after a full two quarters of an hour, Chu Yi finished warming the furnace and took out a spirit grass from the side again.

Seeing this, Liu Lao nodded with satisfaction, this time, there was no problem with Chu Yi's warm furnace. This little guy is really smart.

Chu Yi carefully put the Hui Spirit Grass into the Dan Furnace, and then began refining the Spirit Grass again.

After about a quarter of an hour, the Hui Spirit Grass was finally refined into a small ball of spiritual liquid. Chu Yi raised his hand to take a shot, and the spiritual liquid flew directly out of the Dan furnace and entered the jade bottle in front of Chu Yi.

Chu Yi grinned, and then took out another elixir from his side with a solemn expression, just as Chu Yi was about to put the elixir into the Dan furnace.

"Ahem!" I heard Liu Lao suddenly cough a few times behind Chu Yi, and Chu Yi looked back with some confusion.

"Take a look for yourself, the spirit grass you just refined, and then decide whether you want to start refining this elixir. ”

Hearing this, Chu Yi put the elixir in his hand back to its original place. Picked up the jade bottle in front of him, and in this jade bottle, it contained the spiritual liquid obtained from refining the spirit grass.

Chu Yi stretched out his hand to take out the spiritual liquid, and used his spiritual power to float it in the air, Chu Yi carefully looked at the spiritual liquid he had refined, and then was stunned.

How could this be? Chu Yi looked at the spiritual fluid floating in front of him in disbelief.

I saw some visible impurities floating in the spiritual liquid, even if he was a novice, he knew that such a spiritual liquid could never be used for alchemy.

Chu Yi looked up at Liu Lao, this is the benefit of having a master, you can ask without moving!

Liu Lao looked at the disciple in front of him who was a little hit with a smile on his face, "When you were refining the spirit grass, you didn't quench the impurities in it, and now this ball of spirit liquid can be said to be wasted." ”

Refining the impurities in it? Chu Yi nodded, did not speak, and directly turned around and took out another Huiling Grass, threw it into the Dan furnace, and began a new round of refining.

This time, Chu Yi had been refining for half an hour before he took the spiritual liquid out of the Dan furnace.

Chu Yi stared at the spiritual fluid in front of him with a satisfied expression, which was significantly smaller than the previous one.

I saw that in the spiritual fluid this time, there were no impurities that were visible to the naked eye before, and there were only the spiritual fluids that looked quite pure.

Chu Yi carefully put the spiritual liquid into the jade bottle, then took out another elixir from his side and threw it into the Dan furnace.

Two hours later......

Chu Yi let out a long breath, and finally finished refining all the elixirs.

In these two hours, he had refined three elixirs, and ordinary medicinal materials had even abolished five medicinal herbs.

But fortunately, Chu Yi finally succeeded in refining all the elixirs and the essence of medicinal materials.

Next, it is the fusion that Master said. Chu Yi carefully took out the spiritual liquid obtained by refining the spirit grass, and then put it into the Dan furnace.

Immediately afterwards, Chu Yi put the essence refined from the previous mundane medicinal materials into the Dan furnace.

Chu Yi carefully used his spiritual power to slowly approach these two groups of spiritual liquid, and then began to fuse them little by little.

However, the two groups of spiritual fluid had just fused a small half, and I saw that the two groups of spiritual fluid suddenly repelled each other. Even because one of them is made up of mortals, the force of repulsion is still very weak.

But it still made Chu Yi a little hurried, but after half a burnt incense, the two balls of spiritual liquid suddenly turned into some useless residues.

Chu Yi sighed a little helplessly, although he had long known that the process of fusing elixir was not easy.

But as soon as he fused the two balls of spiritual fluid, he found that the fusion of this elixir was even more difficult than he had imagined, and he barely managed to hold on for a quarter of an hour.

However, the problem that had just arisen, he felt that he had already understood, it was the repulsion between these two masses of spiritual fluid.

Chu Yi once again refined a Huiling Grass, as well as other mortal medicinal materials, and then began the second round of fusion.

After a cup of tea, I only heard the sound of "poof", and the two balls of spiritual liquid turned into residue again.

Chu Yi was no longer in a hurry to start the next round of fusion, but recalled in his mind the process of fusing the spiritual fluid just now.

After discovering that he had just made a few minor mistakes, Chu Yi reached out with some hesitation to take out the residue in the Dan furnace, and then put in another Huiling grass.

At this time, Liu Lao looked at Chu Yi with a smile on his face, his apprentice was really worry-free, and in the case that he could find the problem himself, it was better not to give too many instructions.

When refining the Hui Ling Grass this time, it may be that Chu Yi was already a little anxious at this time, and when the Hui Ling Grass was just halfway refined, it suddenly turned into ashes and fell to the bottom of the Dan furnace.

Chu Yi's face sank when he saw this, and he also felt that he was indeed a little anxious just now.

Suddenly, Chu Yi's heart moved, and he directly crossed his knees, and then closed his eyes,

"The avenue is invisible, giving birth to the world, the avenue is ruthless, running the sun and the moon, the avenue is nameless, and all things are nourished for a long time, I don't know ......"

It was the Pure Heart Mantra that Chu Yi had bought from the Scripture Building before.

And Liu Lao was also stunned when he saw this, a mantra to clear his heart?

Liu Lao grinned, he really didn't lose his own apprentice, and he actually knew that he would recite the heart mantra at such a time. You must know that there are many inner disciples, but they have never even heard of the name of this Pure Heart Mantra.

After about a stick of incense, Chu Yi reopened his eyes, and then directly took out the last Huiling Grass from the side, threw it into the Dan furnace and began refining.

This time, the refining of Chu Yi's elixir was much smoother, whether it was the refining of the Huiling Grass or several other mortal medicinal materials, there were no problems.

Chu Yi once again began the fusion of elixirs......

After about a stick of incense, Chu Yi looked at the spiritual liquid floating in the Dan furnace, and couldn't help but sigh a little in his heart, it was finally successfully fused.

After exhaling a long breath, Chu Yi took out the previously refined spiritual liquid from a jade bottle in front of him, and then directly threw it into the Dan furnace.

Cautiously began the fusion between the elixir and the elixir.

......

Chu Yi's face was a little pale at this time, looking at the Dan furnace in front of him, the fusion between this elixir and the elixir produced the repulsiveness, which was really not comparable to ordinary medicinal materials.

It took him two full hours, trying to fuse elixir with elixir again and again.

As a result, none of them succeeded, and even the best one only lasted for a quarter of an hour or so, fusing less than fifty percent of the two balls of spiritual fluid.

Chu Yi had not much spiritual power left in his body at this time, not only that, but his current mental state was also plummeting.

If the refining continues, there is no chance of success.
