Half a day later.

At this time, Ye Bai was engrossed in controlling the flames, this was already his seventh refining, and the previous six had ended in failure.

Although they all failed, Ye Bai was not without gains, at least he was much more proficient in flame control.

"Almost!"

Looking at the Dan furnace in front of him, Ye Bai muttered in his heart, he was almost ready to produce Dan.

As Ye Bai's hands kept pinching out, a fragrance came out of the Dan furnace.

"It worked!"

Ye Bai's face showed joy, and with a pinch of the magic trick, the flame was extinguished.

"Alchemy Proficiency +1"

A mechanical prompt sounded in his mind, and immediately Ye Bai lifted the Dan Gai, only to see that there were nine pills lying in it at the bottom of the Dan Furnace.

He took the nine Bigu Dan out of the Dan furnace and put them in a bottle, and looked at one of them.

The surface of Bigu Dan is not smooth, indicating that the refiner's technique is rough and contains more impurities.

"With this experience, I believe that the refining will get better and better!"

After putting the Bigu Dan in the storage bag, Ye Bai began the second refining.

With the first experience, the second time is more familiar.

"Whew!"

Soon, the flames were rekindled in the chamber.

................

"Dada!"

In the secret room, Ye Bai put Bigu Dan into a bottle, and at this time, the entire ground was full of bottles of Bigu Dan as far as the naked eye could see.

As Ye Bai refined again and again, his proficiency continued to improve, and in the end, refining Bigu Dan was as simple as drinking water.

"Alchemy: LV2 (1/100)"

"The level of alchemy has increased!"

Glancing at his profession, his level has been increased by one level, and there is no proficiency improvement in refining Bigu Dan.

"Bigu Dan doesn't have proficiency, so you need to refine other pills!"

After perceiving that Bigu Dan was not able to improve his proficiency, Ye Bai set his eyes on another elixir.

Lingyuan Dan, a second-grade pill, is suitable for cultivating qi and cultivating monks below the five-layer foundation, although the effect of this pill is amazing, but the price of the pill is also expensive, and a Lingyuan Pill costs five spirit stones.

To refine the Lingyuan Pill, you need an elixir, and the cost requires twenty spirit stones, if you refine the Cheng Dan, it's okay, if you can't refine it, then these twenty spirit stones will be lost.

Stick the jade cylinder of Lingyuan Dan on your forehead and inject spirit into it.

"Devil's Grass"

"Mizumoto Flower"

"Louver Branch"

.......

There are as many as ten kinds of elixirs, and it makes people headache to see them, after all, extracting these elixirs from the spiritual liquid is also a big project.

"No wonder those alchemists need to recruit some alchemy apprentices to help with chores, if they really let them do it alone, it will simply exhaust them to death!"

Putting down the jade tube, Ye Bai said with a wry smile.

Especially those shops that sell pills, the assembly-line operation is simply handed over to the alchemy apprentices, and the rest is handed over to the alchemists.

After reading the jade tube, Ye Bai began the extraction of the elixir.

"Whew!"

Blazing flames erupted from the mouth of the fire, and Ye Bai slowly put an elixir wrapped in mana into the flames to extract it.

When Ye Bai was extracting the elixir, he was in the secret room one floor below.

A young man's hands pinched out the magic trick like lightning, controlling the temperature of the flames.

"Snort!"

White mist erupted from the Dan furnace, and a scorching smell permeated from it.

The young man also noticed this burning smell, his face stiffened, and he did not dare to relax. But no matter how much he tried to save it, it was useless.

"Failed!"

The young man showed an ugly look, and with a wave of his sleeves, the Dangai was lifted, and a black mist slowly rose.

At the bottom of the Dan furnace, three pills were lying in it, but they were as black as ink, and they had failed to refine and had become a waste pill.

"Fail three times, succeed once!"

The young man muttered.

If Ye Bai was here, he would definitely recognize this young man, he was Yu Heng, who had a relationship with Ye Bai.

But apparently at this time, he was stumped by the problem of alchemy, and his brows were tightly locked.

"The second-grade pill Lingyuan Pill is not easy to refine!"

Yu Heng muttered.

At this time, Yu Heng was also refining the second-grade elixir Lingyuan Dan, but even though he was already an alchemist, the success rate was not high, after all, Lingyuan Dan belonged to the second-grade best elixir, and ordinary alchemists did not dare to say that they could refine it 100%.

As for why Yu Heng wants to refine the Lingyuan Pill, of course, it is for the spirit stones, after all, the spirit stones sold by the Lingyuan Pill are not expensive, and not all alchemists are very rich, after all, if you want to learn alchemy, then you need to invest, and it just so happens that Yu Heng is one of them, a relatively poor alchemist.

Don't look at him to get the badge of the Shendan Sect, but his fame is also limited to being famous in the sect, if it is placed in the Shendan Sect, he is just an ordinary alchemist, and without the guidance of a famous teacher, his attainments in alchemy are also at a point where he is not up or down.

Because of this, Yu Heng planned to refine the Lingyuan Pill, and if he wanted to increase the success rate, the only way was to keep practicing.

..............

"Whew!"

Half a day later, as soon as Ye Bai's magic recipe was collected, the flames began to disappear, and his face showed joy, because a Dan incense permeated the Dan furnace.

"Alchemy Proficiency +1"

"It worked!"

Hearing the prompt sound of the system, Ye Bai showed joy, and hurriedly lifted the Dan cover, and at the bottom of the Dan furnace at this time, there were five round pills, and a stream of aura rose from the Dan furnace.

Just took a casual breath of aura, which shocked Ye Bai's spirit.

"Five Lingyuan Pills, the rate of Cheng Dan is also good!"

Seeing that there were five Cheng Dan, Ye Bai couldn't help but nodded. After all, the first refining could be successful, and the success rate was so high, he couldn't help but be happy.

"Let's see how it goes!"

Put four in the bottle, one of which Ye Bai of course takes by yourself and try the effect.

"Click!"

After taking the pill, Ye Bai's face turned red, and in the meridians, an abundant aura rushed into the dantian.

"Nine Shadows Thunder Technique!"

Feeling the aura in the dantian, Ye Bai ran the exercises and converted the aura into thunder aura.

"Zizi!"

Wisps of thunder bloomed on the surface of the body, making a crackling sound.

After half a ring, the thunder on Ye Bai's body disappeared, and he opened his eyes slightly, and a look of surprise flashed in his eyes, "With the assistance of Lingyuan Dan, you can reach the sixth level of qi cultivation in about a month!"

I have to say that the effect of the Lingyuan Pill is very good, if Ye Bai alone absorbs the aura between heaven and earth, it will take at least several years of hard work to do it.

"The rest of the effort is to refine the spirit element to improve the proficiency of alchemy, and improve the cultivation over and over again!"

Touching his chin, Ye Bai muttered.

"Whew!"

Soon, the entire secret room was lit up again, and Ye Bai once again turned into an alchemy maniac.
