I asked you to seize the opportunity, but you also seized your senior sister?

Lin Yuan nodded secretly and wrote down the words of the disciple of Liao Ji. At the same time, he was also very interested in this Senior Sister Qingyue.

Don't get me wrong, it's not that kind of interest.

Lin Yuan felt that since Senior Sister Qingyue could break through to Yuan Dan so quickly and become a fourth-grade alchemist in just one year.

Then she must have a lot of opportunities!

In the future, I must find an opportunity to get to know her. Maybe there will be unexpected gains.

Lin Yuan left Liao Ji and walked towards the alchemy room according to the room marked by his hand card.

Soon.

He came to No. 6 in District D, where the disciples of the alchemy room had already received the news and opened the door of the Li room in advance.

After Lin Yuan showed his hand card, he went directly into the room.

The layout of the alchemy room in District D is relatively simple. In addition to a portable medicine rack, there is only a set of tables and chairs, and a huge alchemy furnace.

Lin Yuan has studied the true solution of alchemy and knows that the alchemy furnace in front of him is the most common earth fire furnace.

The flame it uses comes from the ground fire in the ground veins under the mountain gate. The firepower is relatively stable, but the shortcomings are also obvious.

The temperature of the ground fire has an upper limit. Using the ground fire furnace, at most, you can only refine elixirs of no more than three grades. If the quality is higher, the temperature of the ground fire furnace is not enough.

Lin Yuan did not aim too high. After he simply familiarized himself with the operation of the ground fire furnace, he took out a set of herbs needed for the first-grade Qi-recovering pill from the storage bag.

The first-grade Qi-recovering pill is the simplest and easiest to refine among all the first-grade pills.

It uses only two kinds of medicinal materials, moonlight grass and vitality flower.

These two herbs can be found everywhere, and the planting conditions are simple. Even many ordinary people without martial arts cultivation at the foot of the mountain can plant them and sell them to the sect in exchange for spirit stones.

"According to the explanation of alchemy, to refine this kind of elixir, as long as you master the balance of fire and let the medicinal properties of the two herbs blend with each other, you can make the elixir."

Lin Yuan silently recited the method of refining Huiqi Dan. After putting the two herbs into the elixir furnace, he began to stimulate the vital energy and control the earth fire furnace.

At the beginning, the process of melting the two herbs was very dull.

Lin Yuan only needed to inject the vital energy, and the earth fire furnace would provide a constant supply of fire to force out the medicinal properties of the two herbs.

But.

After the medicinal properties of the two herbs were extracted, it was time to fuse them. Lin Yuan was about to increase the supply of vital energy and increase the firepower of the earth fire furnace. As a result, a puff of black smoke suddenly came out of the earth fire furnace.

Lin Yuan's first elixir refining failed.

Looking at the two pools of black liquid flowing out of the waste hole of the earth fire furnace, Lin Yuan frowned slightly.

He was obviously refining according to the method in the true explanation of alchemy, but before he could increase the supply of vital energy, the two medicinal liquids could not be fused because the temperature was not high enough, and they became mushy.

This made Lin Yuan feel a little unacceptable.

However, he was not the kind of person who was easily discouraged.

After the first failure, he almost did not stop for a long time. After figuring out the problem in his operation, he started the second attempt directly.

Put in medicinal materials, refine, and increase the temperature.

This time, Lin Yuan started to increase the vital energy injection half a second in advance, and there was no more black gas coming out of the earth furnace, which made him flash a trace of satisfaction in his eyes.

Result.

Before Lin Yuan could be satisfied for too long.

There was a strange sound in the earth furnace, and then the billowing black smoke visible to the naked eye came out. In a few seconds, the whole room was filled with a pungent smell of mushy.

"Cough cough."

Lin Yuan coughed twice and hurriedly urged the vital energy to dispel the black smoke.

He looked at the earth furnace helplessly, not knowing where he had gone wrong this time.

After recalling the contents of the true explanation of alchemy, Lin Yuan finally understood that the firepower of the furnace is not constant during the process of alchemy.

The firepower required for the pill is different at different stages.

If the temperature is high, the medicinal materials will easily become mushy, and there may even be a risk of the furnace exploding.

If the temperature is too low, the medicinal properties in the liquid medicine cannot be completely integrated, resulting in the failure of the pill to finally take shape.

The situation just now was because Lin Yuan did not reduce the output of vitality in time, causing the temperature of the liquid medicine to become mushy during the refining process.

Fortunately, the two herbs used in the Qi-recovering Pill have relatively mild medicinal properties, so there was no furnace explosion.

After Lin Yuan understood this, he quickly started his third attempt.

This time.

During the entire operation, his luck value was almost full, and there were no major mistakes every time he adjusted his vitality.

Unfortunately, because Lin Yuan was too conservative during the operation, the final pill did not take shape successfully. The final product was not a real first-grade Qi-recovering pill, but a Qi-recovering powder that is common on the market and is lower than the Qi-recovering pill.

However, even so, Lin Yuan did not feel sorry.

This was only his third attempt, and he successfully refined a semi-finished product. If he had a semi-finished product, would he be far from success next?

Facts proved.

Lin Yuan underestimated the difficulty of refining pills.

Until late at night, Lin Yuan's next dozens of attempts ended in failure.

Either the fire was too high, the medicine liquid became mushy and emitted black smoke, or because he was too cautious, the temperature was insufficient when the pill was finally formed, resulting in only a semi-finished Qi-recovering powder.

It was also fortunate that the Qinghualong Jue that Lin Yuan practiced could provide him with a continuous supply of vitality recovery. If it were someone else, after dozens of attempts, the vitality in his body would have been drained long ago.

What Lin Yuan didn't know was.

If other alchemists knew about his process of refining pills, they would definitely be shocked.

Most alchemists, when they first started to refine pills, had to go through hundreds or thousands of attempts before they could refine a semi-finished Qi-recovering powder.

Even Sister Qingyue, who was praised by the disciples of the registration office, took a full week to successfully refine the first bottle of semi-finished Qi-recovering powder.

Despite this, Sister Qingyue at that time had already shocked her alchemy teacher and was called an alchemy talent by him.

Lin Yuan naturally didn't know this.

Now, his mind was full of how to successfully refine pills.

After a short rest to recover, he started a new attempt.

Thanks to the storage bag left by the senior brother, which contained a nearly huge amount of medicinal herbs, Lin Yuan had the opportunity to try and fail again and again.

This time.

Lin Yuan looked at the furnace with full concentration, using the mental power he cultivated through the Ancient Scripture of Destroying Gods to keep an eye on the situation of the medicine liquid.

Whenever the medicine liquid was about to boil, Lin Yuan would slightly control the output of his vital energy, and when the temperature of the medicine liquid was slightly lower and the two liquids were about to separate, he would immediately increase the supply of vital energy.

Finally, when the east was white and the first ray of morning light fell on the gate of the Cangjian Sect.

The furnace in front of Lin Yuan also happened to emit a burst of white smoke with a fragrant smell of medicine.

The first-grade Qi-restoring Pill, a perfect pill!
