Primordial Qi

Alchemy requires the preparation of raw materials, an alchemy furnace, some auxiliary items, and even a cold liquid that can extinguish any excess flames on the alchemy furnace at any time to avoid the furnace exploding.

Gu Chenyu naturally understood these common sense. He had asked Gu Qingxue to condense a lot of cold liquid and put it in a jade bottle. Now that everything is ready, he has rented a cave and is ready to start refining the elixir.

The art of controlling fire is very easy to learn, but how to control the temperature is a difficult problem.

A small alchemy furnace was placed in the middle of the cave. Gu Chenyu used his spiritual power to pull it and let it float in the air. He opened his hands, suspended the other spiritual powers in the air, and then put them into the alchemy furnace in order.

The Qianhai Earth Core Flame in his hand also flew to the bottom of the alchemy furnace to heat it, and a spiritual medicine was quickly turned into ashes by the high temperature.

"No, although this flame is relatively gentle, the temperature is still too high for these spiritual medicines. We have to control the temperature properly."

Gu Chenyu wiped the sweat from his forehead. The elixir he refined was called Huiling Pill, a first-grade elixir that required only four kinds of ingredients. In the pharmacy, basically ten low-grade spirit stones were used for one ingredient. Gu Chenyu directly prepared hundreds of ingredients, determined to succeed at least once.

"Just try one strand at a time."

A ray of fire flew into the alchemy furnace, and Gu Chenyu wrapped the elixir with his spiritual power. After a period of time, pure spiritual liquid was refined out.

Huh, the prototype of the elixir.

Gu Chenyu did not dare to be careless, he had failed for seventy times. It was obviously not okay to fail so many times with so many good equipment. There were still many impurities in the embryonic pill. Gu Chenyu directly used the seed fire to calcine it, and the pill shrank violently, and then exploded with a bang.

The lid of the alchemy furnace flew into the sky and was directly inserted into the cave. Gu Chenyu's face was covered in black and gray, and he looked very embarrassed.

"Failed again..."

He exhaled a puff of black smoke, and the explosion came so fast that he didn't even have time to fall down with the cold liquid.

"The medicinal properties are not conflicting, but why is it so difficult to refine the elixir?"

Gu Chenyu sighed helplessly, and then found the key point. After the extreme compression, the spiritual liquid did not become a pill, but exploded. If there was a carrier in it, it might not be too difficult to bear. The pill recipe only had those materials, but no specific refining method. If you want the refining method, you have to pay extra money. Gu Chenyu was naturally unwilling to pay the spiritual stone, and then he fumbled for a long time without success.

Taking out a pill, Gu Chenyu smelled it and found it had the fragrance of elixir.

Yes, the elixir itself is the prototype of the elixir, and after tempering, it can be broken into pieces and used as a carrier for the elixir.

Thinking of this, Gu Chenyu immediately refined the elixir. After the spiritual liquid was refined, he did not choose to throw it away, but instead mixed it together and molded it into the shape of a pill.

The refined spiritual liquid was quickly divided by Gu Chenyu into several pill-sized pieces, a total of six pill embryos. Gu Chenyu refined six Soul-Returning Pills in one furnace.

Looking at the black pill in his hand, Gu Chenyu was a little undecided for a moment. Can this thing really be eaten?

Gu Chenyu swallowed his saliva reluctantly. It tasted bitter and had an indescribable taste.

Gu Chenyu couldn't help but spit out the pill. It had melted a lot and was very different from the described Huiling Pill. He couldn't help but run to the alchemy hall. Gu Chenyu looked up a lot of books before he knew what was wrong.

Pills of the third grade and below need to be refined into pill embryos first, and these pill embryos need to be based on raw materials, which need to be refined together with the spiritual medicine. After the spiritual liquid is refined into a thick consistency, the pill embryo can be refined.

Constantly condense and blend the medicinal power to avoid the conflict of spiritual power and cause the furnace to explode. Gu Chenyu couldn't help but feel ashamed and scratched his head a little embarrassedly. After staying in Lingmu Sect for so long, he only knew how to distinguish spiritual medicines and occasionally watched Bai Yansha refine pills. However, the refining methods were all ordinary pills, which were very different from the refining of these pills, but they also had infinite magical uses.

There are three basic refining methods, the most basic of which is the pill embryo refining method. Once you become proficient in it, you can directly refine pills, skipping the pill embryo step.

Back in the cave, Gu Chenyu started to refine the pills directly. His initial idea was correct. Those pills needed a carrier. Unless one had very strong control, the furnace would explode like Gu Chenyu.

First, rub the spiritual liquid into a ball, and then ignite the pill fire to temper it. Several spiritual herbs are instantly refined into spiritual liquids, and Gu Chenyu stabilizes the spiritual liquids in the pill embryo.

Sure enough, the spiritual medicine on the pill embryo became extremely thick, and the medicinal power began to combine. Gu Chenyu directly increased the firepower, and the surface of the pill began to turn black. Within an incense stick of time, these spiritual liquids had been completely refined.

The fist-sized pill embryo gradually became smaller. The spiritual power was blown away on its surface, and the impurities were blown away like ashes.

There is a play!

Unable to resist the excitement in his heart, his soul could sense that the prototype of the elixir had begun to condense. Gu Chenyu controlled these elixirs to continuously compress and combine them into one. After another hour, the pill the size of a fist was finally refined.

"Hahahaha, I am indeed a genius." Gu Chenyu said complacently.

When he opened the furnace lid, the fragrance of elixir rushed into his nostrils. Gu Chenyu took a closer look and found that it was actually a charred ball.

With a frown, he took out the pill and blew away the impurities on the surface in one breath. An egg-sized pill emitting spiritual energy fluctuations appeared in front of him.

This, is so big?

The corner of Gu Chenyu's eyes twitched. Other people's longan-sized pills turned into goose eggs in his hands.

I don’t know what the effect is, this is simply an enhanced version of the Huiling Pill.

Sneaking to the place where Qingming Sect raised monsters, Gu Chenyu caught a monster in the Gathering Spirit Realm and beat it up, forcing it to swallow the elixir to see its effect.

This was a crane in the Spirit Gathering Realm. Gu Chenyu knocked it out with a soul attack when it wasn't paying attention, and then exhausted its spiritual power before feeding it the Soul Restoring Pill. After a while, the crane recovered its spiritual power and chased Gu Chenyu, pecking at him all the way. The effect was simply too good to be true.

This pill is good for monsters, but not for humans, as they cannot withstand its power.

After all, it is just a first-grade elixir, a low-level elixir corresponding to cultivators in the Nourishing Qi Realm. There are also high-level Huiling Pills, which require other spiritual medicines to refine.

The right amount of elixirs made from the right spiritual medicines are the right elixirs for human cultivators to use. Gu Chenyu refined it again, and one furnace could produce about twelve elixirs.

One medicinal material costs ten low-grade spirit stones, but one Soul-Restoring Pill costs thirty low-grade spirit stones. Twelve pills are refined in one furnace, which means three hundred and sixty low-grade spirit stones. After deducting the cost, the net profit is three hundred and fifty low-grade spirit stones.

Huge profits, really huge profits.

Gu Chenyu seemed to have seen an opportunity to make a fortune. No wonder everyone in the Medicine Refining Hall was so wealthy. So that's why.

Of course, the net profit cannot be calculated in this way. After deducting other costs, Gu Chenyu makes a net profit of 200 low-grade spirit stones for one furnace of pills, which is also a huge profit.

After some trial and error, Gu Chenyu successfully refined the remaining pills. Their color became better and better, good enough to be sold.

"What? The recycling price of a Soul-Returning Pill is only ten low-grade spirit stones?"

Gu Chenyu looked at the people from the Medicine Refinery Hall in disbelief. He originally wanted to sell it himself, but time waits for no one and he is not a professional salesperson, so he thought about selling it to the Medicine Refinery Hall. He didn't expect the price to be cut in half.

What a profiteer!

Gu Chenyu silently took back the elixir. He would rather keep it for himself than let these profiteers take it away. He had plenty of spirit stones anyway, so if he didn't have any, he could just ask Gu Qingxue.

The refining of pills comes in different sizes, and they are usually the size of a longan, which can be swallowed in one bite. Gu Chenyu bought hundreds of raw materials for Huiling Pills in one go. During the refining process, the furnace exploded seven times. He refined thousands of pills, of which 700 were high-quality and more than 370 were defective.

All the defective products were handed over to Gu Qingxue, who used them to play with her spiritual pet. She had a little rabbit, and it was estimated that it would reach the spiritual gathering realm in a while, so it would be beneficial to eat some spiritual restoration pills.

After staying awake for three consecutive days, Gu Chenyu felt his soul a little tired. He slept for a whole day before waking up. Then he ran to the medicine hall to buy raw materials, as if he was addicted, working day and night.
