217: Chapter 217 Surprise

Zhao Feiyu had also once asked for information regarding this type of alchemy furnace.

This type of alchemy furnace was manufactured by a producer on Giant Whale Island.

Besides this mid-grade alchemy furnace, there were also low-grade alchemy furnaces, although their intelligent systems and furnace quality were both inferior.

The high-grade alchemy furnace had even better quality, and it had over thirty types of elixir formulas pre-recorded inside.

It could be said that as long as you had such an alchemy furnace, you could become an alchemist.

However, the elixir formulas in the alchemy furnace were all common, dime-a-dozen recipes, and even the elixirs refined from them had no real value to speak of.

Some were even worse than the medicine found in a pharmacy.

After preparing everything, Zhao Feiyu opened the alchemy furnace, then circulated the Martial Spirit Elixir Formula Art, and began to put the medicinal herbs into the furnace one by one according to the method above.

At this moment, the temperature inside the alchemy furnace was at an optimal level.

Once the medicinal herbs entered, the loss of their medicinal properties could be greatly reduced.

"Cistanche, 350 grams!" "Epimedium, 25 grams!" "Astragalus Seed, 35 grams!"

After learning the Martial Spirit Elixir Formula Art, Zhao Feiyu's control over the weight of medicinal herbs had reached an almost perfect level.

As long as the medicinal herbs passed through his hands, he could immediately know their weight.

Subsequently, Zhao Feiyu first started the refining process using the alchemy furnace's own electrical energy.

As the temperature gradually increased, the medicinal herbs inside began to melt slowly.

But just at this moment, Zhao Feiyu suddenly discovered that the heat from the electrical energy was uncontrollable, and the medicinal herbs inside seemed to be entering a charred state.

Seeing this, Zhao Feiyu immediately circulated his internal energy and transmitted it through the alchemy furnace's transfer port.

After Zhao Feiyu's internal energy entered the alchemy furnace, under the circulation of the Martial Spirit Elixir Formula Art, Zhao Feiyu immediately had clear control over the environment inside the furnace.

His internal energy entered the alchemy furnace from his right hand to begin refining the medicinal herbs, and then, mixed with traces of the herbs' energy, it was transmitted into Zhao Feiyu's body from his left hand.

This was the miraculous aspect of the Martial Spirit Elixir Formula Art: absorbing the medicinal spirit energy to condense a Golden Elixir and strengthen oneself.

Not long after, as all the medicinal herbs were completely refined, the alchemy progress reached the purification step.

The alchemy process was divided into a total of nine steps.

The first step, furnace washing, was to clean the alchemy furnace and dry it.

Because previous alchemy furnaces were relatively simple, they had to be cleaned inside after every refining session.

But the alchemy furnace used now did not require this; for example, the alchemy furnace in Zhao Feiyu's hand had a self-cleaning effect.

The second step, adding medicine, was to input the spirit herbs.

The third step, liquefying medicine, was the liquefaction of spirit herbs, which relied on the alchemy fire to liquefy the medicinal herbs.

This alchemy fire was catalyzed by an Ancient Martial Artist's internal energy.

Currently, the alchemy fire of this alchemy furnace could also be replaced by electrical energy, but the effect was far inferior to internal energy.

The fourth step, purification, was to extract the effective medicinal power and then remove the useless or harmful parts.

After purification, it reached the fifth step: isolation.

The design inside the alchemy furnace was extremely complex.

Its overall structure consisted of the furnace body, furnace lid, main chamber, isolation chamber, alchemy fire chamber, alchemy fire, slag discharge port, energy supply interface, and other structures.

The isolation step required transferring the liquefied medicinal herbs into the isolation chambers in an organized manner, preventing them from fusing with other medicinal liquids and causing a mixture of medicinal powers.

Depending on the grade of the alchemy furnace, there were several isolation chambers.

The sixth step was fusion, transferring the medicinal liquids from the isolation chambers into the main chamber, fusing them according to a certain ratio.

The seventh step was spirit injection, utilizing one's own internal energy to inject it in, allowing the medicinal liquid to effectively transform during the fusion process.

Because every Ancient Martial Artist practiced different techniques, their internal energy characteristics differed, making this a key factor affecting the quality of the elixir and the success rate.

Moreover, this process carried great risk and was a severe test of an alchemist's ability.

If the spirit injection speed was too fast, it often increased the cost of internal energy; if it was too slow, it often increased the time cost.

Judging by the carrying capacity of the medicinal liquid, one had to decide the timing for ending the spirit injection; if it ended too early, some "effective medicinal ingredients" would not be converted, failing to reach the highest quality.

If it ended too late, it would exceed the carrying capacity, increasing the risk of the furnace exploding.

Then came the elixir separation, rapidly cooling the furnace temperature to let it solidify.

Here, in order to distinguish the content of spirit energy contained in the elixirs, the Alchemy Dao had a standard for finished elixirs.

The uniformly specified elixir had a diameter of "one-third of an inch."

In this way, only elixirs of the same type and volume could have meaningful comparisons of their medicinal spirit energy content, thereby defining the quality of the elixir.

Finally, there was the elixir collection.

Upon reaching this step, Zhao Feiyu let out a sigh of relief.

To be honest, the entire process was quite nerve-wracking.

After all, it was his first time refining elixirs, so it would be a lie to say he wasn't nervous.

This thing carried the risk of the furnace exploding.

It was just like cooking with a pressure cooker; you never knew when it might go "bang" and explode.

As the alchemy furnace temperature cooled down, a dozen or so round, brown elixirs rolled out from the elixir exit.

Zhao Feiyu couldn't wait to pick one up and sniff it under his nose, then carefully analyzed and pondered.

The ratio of medicinal spirit energy to volume was fifty times, which belonged to the category of mid-grade elixirs.

"Not bad, not bad. I actually refined a mid-grade elixir on my first try; it seems I have quite a bit of talent!"

Zhao Feiyu was quite satisfied with his achievement.

The judgment of elixir quality could be determined by the medicinal spirit energy.

Secondly, one also had to look at the elixir's appearance.

The appearance characteristics of a mid-grade elixir were perfectly round, with an elixir fragrance, and a "elixir halo."

The so-called elixir halo was the degree of crystal clarity on the surface, similar to a "patina"; the higher the quality, the more crystal clear the surface was.

Zhao Feiyu immediately brought over a jade bottle to store them in, then couldn't wait to swallow one.

Once the elixir entered his stomach, Zhao Feiyu didn't feel anything at first.

But very quickly, a feeling of intense heat surged from his abdomen.

It then slowly sank, spreading throughout his entire body, making Zhao Feiyu start to feel unbearably hot.

At the same time, a surge of lust rose in Zhao Feiyu's heart, making him want to vent it out.

"The effect is this potent?"

Zhao Feiyu, while shocked, immediately circulated the Xuan Yu Vajra Art to start suppressing it.

Bang, bang, bang!

Just at this moment, a knock on the door came.

Suppressing this surge of lust, Zhao Feiyu walked to the door.

"Sister Yafei?"

Seeing who it was, that surge of lust that had just been suppressed immediately flared up again.

"Feiyu, are you not done yet?"

Today, Zhang Yafei was wearing tight bell-bottom pants, which accentuated her slender legs perfectly.

Her hair was simply pulled back, giving her a mature and sexy beauty.

Gulp!

Zhao Feiyu couldn't help but swallow his saliva, then grabbed Zhang Yafei and pulled her into the room.

"Ah! Feiyu, what are you doing?"

Zhang Yafei exclaimed in surprise.

But she saw Zhao Feiyu directly lock the door and then carry Zhang Yafei onto the operation table.

"No, Feiyu, not here, you can't..."

But no matter how Zhang Yafei struggled, Zhao Feiyu was already blinded by the surge of lust.

Over half an hour later, Zhao Feiyu was sitting on the floor, covered in sweat.

However, that surge of lust in his heart was still burning.

"What should I do? What should I do?"

Looking at Zhang Yafei, who was already exhausted, Zhao Feiyu felt a bit guilty.

"Feiyu..."

Zhang Yafei struggled to sit up.

"You are really annoying. Come back to my room with me; I will give you a surprise!"

"Another surprise?"

Zhao Feiyu felt very surprised; what was going on today?
