Li Cangfeng nodded emphatically: "Alright, I'll go prepare the medicinal herbs now. I want to see if you can refine the seventh-grade spiritual pill, the Seven-Turn Heavenly Wind Pill, and what exactly this 'Wind Furnace Cold Refining Method' you mentioned is!"

As soon as he finished speaking, Li Cangfeng strode away.

After Li Cangfeng left, Fang Bingling asked in a low voice, "Mr. Ye, can you really refine the Seven-Turn Heavenly Wind Pill?"

"Of course, do you think I'm lying to him or deliberately trying to annoy him?" Night Wind retorted.

Fang Bingling's face showed deep surprise: "Mr. Ye, you are so amazing, and you can even refine pills. How exactly do you cultivate? By the way, Mr. Ye, how old are you this year?"

"Guess," Ye Feng said with a smile.

"I can't guess." Fang Bingling shook her head with a bitter face.

No matter how much Fang Bingling pleaded and begged, Ye Feng didn't tell her the truth.

Li Cangfeng came downstairs very quickly.

Li Cangfeng prepared all the necessary ingredients for refining the Seven-Turn Heavenly Wind Pill, and even prepared two sets.

There is a chance of failure when refining elixirs, and the higher the grade of the elixir, the greater the chance of failure.

Of course, the higher the skill level of the alchemist who refines the elixir, the greater the chance of success.

At this moment, Li Cangfeng was preparing two sets of medicinal materials for refining the Seven-Turn Heavenly Wind Pill. It was clear that he was very meticulous, and he genuinely wanted to see Ye Feng's abilities, without deliberately making things difficult for him.

"Please," Li Cangfeng said.

Ye Feng didn't stand on ceremony and immediately took out the alchemy furnace and sat down cross-legged.

As Ye Feng cast spells, pure Dragon Emperor True Qi surged into the alchemy furnace.

"rise!"

Ye Feng made a hand seal and gently lifted his hand, causing the medicinal herbs beside him to fly up one after another and fall into the alchemy furnace in a smooth, flowing manner.

With a clang, the lid of the alchemy furnace slammed shut.

A gentle breeze arose in the alchemy furnace, swirling the medicinal herbs around within. As time passed, the breeze grew stronger, and the spiritual energy within the furnace became increasingly abundant.

The essence of the medicinal herbs was thus stripped away by the strong wind, while the impurities were cleared to the bottom of the alchemy furnace and settled down.

This is the cold refining method using a wind furnace.

It is not refined by high temperature, but by spiritual wind containing true energy!

Fang Bingling, the maid, and Li Cangfeng were all standing to the side, staring intently.

However, neither Fang Bingling nor the maid understood anything.

The two of them were at a very low level of cultivation, and they weren't alchemists either, so naturally they couldn't see the profound mystery of Ye Feng's use of the cold refining method in the wind furnace to refine the Seven-Turn Heavenly Wind Pill.

But Li Cangfeng understood some of it!

As the saying goes, experts see the details, while laymen just watch the spectacle.

Fang Bingling and her maid were amateurs, while Li Cangfeng was an expert.

It was precisely because he understood part of it that Li Cangfeng was extremely shocked.

The cold refining method in the furnace that this kid mentioned wasn't a hoax; it was actually true!

This cold refining method in a wind furnace does not rely on high temperatures, but rather on spiritual winds containing spiritual energy to strip away the medicinal properties from the herbs and promote their condensation and sublimation!

Li Cangfeng became increasingly alarmed as he looked at the document, and his expression turned extremely grave.

If it were an ordinary person, seeing Li Cangfeng's serious demeanor, they would definitely become arrogant and complacent.

However, Ye Feng remained focused, as if he hadn't noticed the change in Li Cangfeng's expression, and continued to concentrate on refining the Seven-Turn Heavenly Wind Pill.

Two hours passed in the blink of an eye, and the Seven Revolutions Heavenly Wind Pill was finished being refined.

Ye Feng changed his hand seals again, and the furnace body trembled slightly.

"rise!"

The night wind gave a soft whistle, and the stove lid opened.

A gust of spiritual wind suddenly burst forth from the alchemy furnace, filling the entire third-floor hall of Baiyuantang.

At the same time, a celestial elixir shining with a sky-blue light flew out of the alchemy furnace, riding the spiritual wind and swirling around in the third-floor hall.

Night Wind raised his hand and grabbed the Seven-Turn Heavenly Wind Pill that was flying in the air.

"It actually succeeded on the first try..." Li Cangfeng said in shock.

Li Cangfeng failed countless times before finally succeeding in refining the Seven-Turn Heavenly Wind Pill, but he produced an impure pill and wasted countless medicinal materials.

But now that Ye Feng has successfully refined it on his first try, it naturally shocks him!

"Elder Li, come and see how my Seven-Turn Heavenly Wind Pill compares to yours?" Ye Feng said with a smile, handing the Seven-Turn Heavenly Wind Pill to Li Cangfeng.

Li Cangfeng couldn't wait any longer. He snatched the Seven-Turn Heavenly Wind Pill from Ye Feng's hand and examined it closely.

The Seven-Turn Heavenly Wind Pill refined by Ye Feng was not only larger, but also looked crystal clear. The pill patterns on its surface were not only complete and obvious, but also seemed to be slightly wriggling as if they were alive!

The gentle breeze surrounding the Seven-Turn Heavenly Wind Pill gives one a refreshing and pleasant feeling.

This elixir is practically perfect!

Compared to that, the Seven-Turn Heavenly Wind Pill that I refined was of impure quality, it was as if it was refined with my feet, it was unbearable to look at!

Li Cangfeng is now truly convinced, completely convinced!

Holding the elixir in his hands, he knelt down in front of Ye Feng with a thud.

"Senior's alchemy skills are extraordinary, and I am truly impressed! Senior, please forgive my rudeness just now!" Li Cangfeng said firmly.

Fang Bingling and her maid were both startled.

The two of them never expected that Li Cangfeng, the second-in-command of the Li family and the most skilled alchemist in the Hundred Yuan Hall, would actually kneel before Ye Feng!

This deeply impacted them!

"If you don't mind, please teach me, senior!" Li Cangfeng continued.

Night Breeze smiled and said, "You want to learn my furnace cold refining method?"

Li Cangfeng nodded emphatically.

"But why should I teach you?" Night Wind countered.

Li Cangfeng was speechless for a moment, and after a moment of stunned silence, he said, "Senior, just tell me what you want. As long as it's something I can get or do, I will not be stingy!"

Night Breeze thought for a while, but couldn't figure out what she wanted.

Ye Feng has no shortage of spirit stones or cultivation techniques, but the materials he needs for refining weapons are something that can only be obtained by chance, and Baiyuan Hall probably can't provide any help.

So after thinking for a long time, Ye Feng still couldn't think of what to ask for.

So Ye Feng said, "How about this, you will do three things for me in the future. These three things are definitely within your capabilities and will not harm the interests of your Li family. What do you say?"

Hearing Ye Feng say this, Li Cangfeng was overjoyed.

In order to learn the cold refining method of the wind furnace and master more advanced alchemy techniques, he disregarded everything else.

Ye Feng's request was not excessive, so he naturally did not hesitate!
