"Put a spirit grass into the Dan furnace..."

"Infuse the True Qi into the Dan Furnace..."

"Follow the path in the Dan furnace to run the true qi..."

After writing down the information on the sign, Lin Bai began to do what he said.

The Dan furnace is very small, about five inches, just enough to put down a spirit grass.

After Lin Bai put in the spirit grass, he began to inject true qi into it, and there were passages on the inner wall of the Dan furnace, all he had to do was to fill these passages with true qi.

Gradually, with the infusion of his true qi, those passages in the Dan furnace began to glow, and the temperature in the Dan furnace gradually increased, and at the same time, there were some dots of light shuttling through it.

After half a column of incense.

The temperature inside the Dan furnace seemed to have reached a certain level, and the spirit grass inside also began to slowly seep out a little bit of medicinal liquid.

"Is that the spiritual herb liquid?" Lin Bai thought to himself.

Seeing that the spirit grass began to ooze medicinal liquid, Lin Bai knew that he only needed to maintain the injection of true qi next, and wait for the spirit grass in the Dan furnace to completely turn into medicinal liquid.

After a cup of tea, most of the spirit grass in the Dan furnace had turned into medicinal liquid, and the medicinal liquid slowly flowed at the bottom of the Dan furnace.

At this time, due to the continuous operation of Lin Bai's true qi in the channel, the temperature in the Dan furnace was getting higher and higher, and those dots of light were becoming more and more, and the melting speed of the spirit grass was also a little faster.

"Whew!"

Suddenly, a burning smell came from inside the Dan furnace.

After hearing the sound, Lin Bai hurriedly stopped the injection of true qi, opened the Dan furnace to check the situation inside, and saw that the spirit grass in the Dan furnace had turned to ashes, and the medicinal liquid that had been refined had also been destroyed.

Lin Bai frowned slightly.

What's going on? How did the spirit grass suddenly turn to ashes?

Could it be that the temperature is too high?

After some manipulation, he had basically understood the principle of this Dan furnace, and this Dan furnace should use the method of fire refining.

The method of fire refining was a method of refining medicinal liquid that he had seen in the Wordless Pill Book, mainly using the assistance of high temperature and true qi to refine the spirit grass into medicinal liquid.

However, it is recorded in the Wordless Pill Book that the method of fire refining is an extremely primitive refining method, not only is the amount of true qi injected difficult to control, but also the purity of the refined medicinal liquid is not too high.

If the spirit grass is not careful, it will burn due to the high temperature, and the medicinal liquid that has been refined will also be destroyed.

It seems that this Dan furnace should be heating the spirit grass through those channels inside.

When he knew that this Dan Furnace was using an extremely primitive fire refining method, Lin Bai had already decided to give up using this Dan Furnace to refine the spirit grass.

It just so happened that the purpose of his undertaking was originally to experiment with what he had learned in the Wordless Pill Book, and the next moment he picked up a spiritual grass and began to use the Dan Decision to refine the medicinal liquid.

Although what he had mastered was only the most basic refining pill decision, according to the record in the wordless pill book, the effect of the liquid extraction decision was not known to be many times better than the method of fire refining, and the liquid extraction decision did not need the additional assistance of the Dan furnace.

Then Lin Bai held the spirit grass in his hand, and began to use his true qi to perform one mysterious hand duel, and after he played the last hand duel, an equally mysterious rune entered the spirit grass.

Then the spirit grass began to slowly become crystal clear, and finally turned into a green liquid.

"It's done!"

Lin Bai carefully wrapped the green liquid with his true qi, carefully poured it into a bottle, and finally plugged the bottle with a wooden stopper to be considered complete.

"Whew~"

Lin Bai exhaled and wiped a layer of fine sweat from his head.

Although the whole process seems to be very simple, the amount of mind consumed in it is very large, what Lin Bai needs to do is not only to cast one hand duel after another, but also to integrate the true qi into this hand duel one by one, and finally form that rune into the spirit grass.

And the amount of true qi that needs to be consumed when using Dan Decisive is also a lot, even if Lin Bai has the True Qi Fire Dragon, he can only cast it twenty times in a row at most, you must know that he is an Extreme Realm martial artist, and the quality and quantity of True Qi are much higher than ordinary martial artists, and it is conservatively estimated that a martial artist of the same level will deplete his true qi as long as he casts five Liquid Extraction Decisions.

Counting the spirit grass that had just been destroyed, there were still thirteen spirit grasses left, and he still needed to refine nine bottles of medicinal liquid.

Lin Bai picked up the bottle of liquid medicine that had just been refined, shook it, and found that there were very few impurities in it, and put it into a groove in the stone room, and two words appeared on a flat stone platform next to the groove: "Seventy percent."

"Didn't you expect the purity to reach seventy percent?" Lin Bai muttered.

At the same time, he also secretly sighed in his heart that the liquid extract was powerful, you must know that according to what Han Bing said, being able to refine the liquid medicine to fifty percent is considered a first-class alchemist.

There are ten grooves in one corner of the stone chamber, and as long as you put the refined liquid into the grooves, the platform on one side will show the purity of the bottle.

As long as the ten grooves are filled and the purity of the liquid medicine meets the requirements, the task is considered to have been completed, and if it is not completed, it can only be obediently deducted from the contribution.

Next, Lin Bai continued to use the extraction solution to refine the remaining spirit grass, and as the number of refined spirit grass increased, he became more and more proficient.

"It's done!" Looking at the ten bottles of liquid medicine in the groove, Lin Bai stretched his waist and said.

Unexpectedly, among the nine bottles of liquid medicine refined, there was still one bottle with a purity of ninety, and the rest were mostly seventy percent and eighty percent pure.

After the refining was over, there were still four spirit grasses left, and after Lin Bai rested for a while, he refined the four spirit grasses into medicinal liquid.

The task only required ten bottles of medicinal liquid, and the extra four bottles Lin Bai naturally accepted with a smile.

After swiping the sign used to open the stone chamber on the platform, the word "Done" appeared on the sign.

Lin Bai picked up the sign and walked out of the stone room and walked towards the window just now.

"Hello, hand in the task. At this time, there was no one in front of the window, so Lin Bai walked forward and put the sign and his token in front of the deacon in the window.

Seeing that Lin Bai came over to hand in the task so quickly, the deacon muttered in his heart:

"Fifteen spirit grasses have been destroyed so quickly? Ten bottles of refined medicinal liquid are needed to complete the task, which means that this disciple needs to compensate for a thousand contributions? What a loser!"

Thinking of this, the deacon sighed a little:

"It's really a casual task without asking, the person recorded on the token is obviously just a new disciple, although refining the spirit grass does not have high requirements for cultivation, but it requires a lot of technical things, otherwise the spirit grass will be easily destroyed, and this kind of task is generally only a disciple of the Dantang will take over the practice, isn't he a new disciple who contributes too much?"

Then the deacon's face was a little surprised, he was not sure if he was dazzled, he saw the word "done" on the sign so much?

He rubbed his eyes, making sure that he was not mistaken, but in his heart he wondered, how did Lin Bai complete this task?

"Could it be that he prepared ten bottles of liquid medicine in advance, and then put them directly into the groove in the stone chamber...?"

Without waiting for the deacon to finish thinking, Lin Bai saw that the deacon didn't speak for a long time, so he asked:

"What's wrong? What's wrong?"

"Oh... Oh, it's okay, it's your token, and the five hundred contributions you've completed have been transferred to your token. Lin Bai opened his mouth before the deacon came back to his senses, recorded the information and returned the token to Lin Bai.

Lin Bai, who took the token, turned around and left.

"Whatever, I'm just a little deacon...," the deacon muttered after Lin Bai left.
