Then take out a copy of the medicinal materials for refining the healing pill, strychnine, red peony, comfrey, and so on.

Put the Dan furnace on the stone furnace, cover the stone furnace with his left hand, and slightly infuse the spiritual energy, only to see the fire rise sharply in an instant, and a heat wave is coming.

When the temperature in the Dan furnace has arrived, the medicinal materials will be put in order, and the medicinal materials put into the Dan furnace need to be controlled with soul power, so that all the medicinal materials will be melted, and the impurities in them will be removed.

The amount of impurities will affect the grade of Cheng Dan in the later stage.

According to the grade, there are lower grade pills, medium grade pills, top grade pills and best pills.

Generally speaking, the lower grade pill is more than the base, the middle grade pill can be seen occasionally, and the top grade and the best are directly in the legend.

The strength of the soul is reflected in the elimination of impurities, the stronger the soul, the more accurate the control of the soul power, and the more impurities are removed.

But how many people are born with strong souls?

Yi Heng has been cultivating the "Soul Refining Decision" for more than a year, and his soul has only exceeded about thirty percent of the increase, and now the improvement is no longer obvious.

After half an hour, all the medicinal materials have been removed from impurities and turned into a liquid state, and then they should be fused together, which is also a major difficulty.

Many people blindly pursued the elimination of impurities in the front, and used too much soul power, and there was no soul power fusion at this step.

Yi Heng was like this, he had used too much soul power before, and almost all the impurities of every medicinal material had been removed, and now he felt dizzy and unable to control the fusion of the medicinal liquid.

With a "bang", the uncontrollable liquid instantly burned into ashes.

It means that this alchemy has completely failed.

But Yi Heng was not disappointed, he succeeded in the first alchemy, which was obviously difficult to do.

Two hours later, he started the furnace again.

This time, it was not perfect in removing impurities, and the soul power was left to fuse the medicinal liquid, but the soul power was there, and the main and secondary were forgotten in the fusion process, and the same explosion failed.

A day passed, Yi Heng stood up, patted the medicine residue on his body, and walked out of the alchemy room.

When he got to the ground, he took a deep breath, and the cool wind outside made his mood feel a little better.

I practiced four furnaces in one day, but I didn't succeed once.

This is also too shocking, doesn't it mean that people with strong souls have alchemy advantages?

Doesn't it mean that it can increase the success rate of alchemy?

Three spirit stones are used for one day, and four medicinal materials and twelve spirit stones are really too loser, Yi Heng wants to cry without tears.

Fortunately, it was not used to refine the spirit pill, otherwise the loss would be even greater.

The next day, Yi Heng came to the alchemy room again, and after thinking about it all night last night, he once again seriously pondered the alchemy experience and the pill formula, and he felt a lot more confident.

Skillfully input the aura, skillfully turn the Dan furnace, put in the medicinal herbs, remove impurities, and begin to fuse.

After the tea, Yi Heng, who had his eyes closed, smelled the fragrance of the elixir, and he knew that the alchemy had been successful.

Flipping his hand and taking out two jade bottles, with a wave of soul power, he put ten pills into the bottle.

After receiving the aura and soul power, he held the bottle in both hands, leaned to his nose, sniffed it deeply, and was very satisfied.

But how do you feel that the fragrance is much stronger than the last time Zeng Yushu gave him?

He poured out the five grains from the bottle and placed them in his hand, and found that two of them were much more rounded than the others.

Carefully pick up one of them, smell it, and make sure that the strong fragrance must come from here, which means that these two should be better than the others.

I poured out another bottle and found that there was only one such pill.

"Could it be that this is a medium-grade elixir?"

The value of the medium-grade pill is three times higher than that of the lower grade, and it is much better in terms of healing effect.

One lower grade pill is one spirit stone, one medium grade pill is three spirit stones, there are a total of sixteen spirit stones here, and there is not much to lose.

"It's time to try the Gathering Elixir tomorrow, that's the most important thing. ”

Suppressing the excitement in his heart, Yi Heng returned to the courtyard and continued to practice "Soul Alchemy", but he couldn't feel the growth of his soul, and it seemed that he had reached a bottleneck.

In the morning, Yi Heng rushed into the alchemy room again, this time directly handing over fifteen spirit stones, preparing to directly refine for five days.

On the first day, after refining a furnace, after failing, I meditated and cultivated with peace of mind, calmed my mind, and carefully studied the Danfang.

The next day, after refining two furnaces, he still failed, and he was neither happy nor sad.

On the third day, after refining three furnaces, he still failed, and he continued to be silent.

Day 4, Day 5.

When he walked out of the alchemy room, he felt a sense of relief, and all the medicinal materials on his body were refined.

What I got was eight bottles of forty pills of Ju Ling Pill in the storage bag, and there were ten of them in the middle grade pill.

If it is replaced with spirit stones, it will be one hundred and twenty.

This is still only the fourth day and the fifth day of the four furnaces, if all of them are completed, it will be a huge profit.

"It seems that I still have a certain talent for refining medicine, but I can only practice secretly, if I let Uncle Liu know, I must be reprimanded again, and I have to understand and familiarize myself with talismans, formations, and magic weapons. ”

Seven months later, Yi Heng was content in bed.

Looking at the vials full of pills on the bed, his eyes lit up.

For seven months, he mainly went to master talismans, formations and magic weapons, and occasionally secretly went to alchemy.

But what surprised him was that the success rate of alchemy in the future was surprisingly high, at least eight out of ten furnaces, which would definitely be forcibly snatched by the elders of the Alchemy Hall if they knew about it.

What's even more gratifying is that the higher the probability of the appearance of the medium-grade pill in the future, and even five high-grade pills appear.

High-grade elixir, that is the best help to break through the bottleneck.

Take one out of it, and ensure that even the elders will rush to ask for it, and there is no market for it.

Twenty bottles of low-grade Juling Pill, eight bottles of medium-grade Juling Pill, and one bottle of high-grade Juling Pill.

Ten bottles of the lower grade healing pill, five bottles of the middle grade, and two capsules of the upper grade.

You have to change it to a spirit stone, the spirit stone has been used almost, how can I return it to Zeng Yushu when the time comes, last time I heard that there is a trading place from the Tianshan Mountains, you can go there to see it then.

But today we have to break through to the seventh floor first.

After thinking about it, with a wave of his right hand, the vials full of beds disappeared, he sat cross-legged, and began to mobilize his aura to flush the meridians, and in the Purple Mansion, the size of the villain was almost no change compared to a year ago.

I don't know if the effect of "Alchemy" is getting worse and worse, or if it has encountered a bottleneck.

The villain's fingers pinched the fingers, and a stream of soul power flowed towards the gossip plate.

The gossip disk that had obtained this soul power slowly turned.

Faster and faster, the white light produced by the eight characters also began to shine.

Yi Heng only felt a burst of relief, and the aura in the air began to pour into his body in large quantities, helping him to impact and wash the meridians.

An hour later, a loud roar came from the courtyard, and a burst of coercion crushed the bamboo forest behind the courtyard.

Yi Heng stood in the courtyard, feeling more than twice as much aura as the sixth floor, and in his heart he was lucky to win Zhang Shan on the fighting platform.

"I should be able to beat two of my former selves by now. He carefully felt the surging aura rolling in the dantian, and raised his hand to use a fireball, which was very different.

Yi Heng, who was full of joy, calmed down, and now he had to endure and not reveal his cultivation.

If you want to replace the pill in your hand with a spirit stone, you have to find out if there are any special exercises or magic weapons or something, so as to cover up your rapid growth in cultivation, so that others can't see it clearly.

It's been two years, and it's time to go down the mountain.
