Just as Qing Feng was hesitating about Ding Fan's words, his master unexpectedly appeared at the doorway, instructing him to follow the other's suggestion. For a moment, Qing Feng was utterly astonished. Could it be that the method Ding Fan mentioned was actually true?

Qing Feng clearly knew that he had been an alchemist for some time now. He had seen and heard much about alchemy, but he had never heard of preserving spiritual materials in an alchemy cauldron. Importantly, he was his master's apprentice, and his master had never mentioned such a method. His master had taught him everything with utmost dedication, so clearly, even his master didn't know about this method.

Yet here was a mere cultivator, seemingly at the Early Nascent Soul Stage, speaking with such confidence. How could this not be shocking? It was truly an unbelievable thing!

Who was his master, after all? One of the few Alchemy Masters in the entire Donglai Continent. But even his master had never heard of such a method, and now it was being spoken by a young man. This was simply too unbelievable!

For a moment, Qing Feng's mind was at a loss. But after being stunned for a while, he still followed Ding Fan's method and preserved the spiritual materials that were being refined in the alchemy cauldron.

After Qing Feng did as Ding Fan instructed, the aroma from the spiritual materials being refined in the alchemy cauldron was indeed completely sealed, clearly preserving them all. Witnessing this, Qing Feng's face was filled with astonishment, utterly stunned by Ding Fan's method!

The two children, seeing the scene with the alchemy cauldron, were also extremely shocked, clearly not expecting Brother Fan to know so much about alchemy and even understand the method of preserving spiritual materials. This was simply too incredible!

Additionally, the two children were amazed because their master had agreed to Brother Fan's approach, allowing the eldest apprentice brother to secretly follow it. Both the boy and girl understood that their master was not someone who would take chances, especially since the Eight Treasures Pill was extremely precious even to their master.

After all, the spiritual materials needed to refine the Eight Treasures Pill were not common; they were not easily obtained. Both children knew that if it were not for the many precious spiritual materials their master possessed, it would be impossible for the eldest apprentice brother to restore the ancient recipe for the Eight Treasures Pill.

Even though their master had plenty of spiritual materials, the two children knew these materials were very precious, and not easily available to ordinary cultivators, so they could not be wasted lightly. Their master clearly had extremely high expectations of them in this regard and naturally wouldn't allow the eldest apprentice brother to waste materials recklessly.

Therefore, the two children understood that since their master had agreed to allow the eldest apprentice brother to follow Brother Fan's method, it was evident that the master had great trust in Ding Fan's approach.

However, there was something the two children couldn't understand. If the master agreed so much with Ding Fan's method, why didn't he teach it to them? Knowing that Brother Fan's method would significantly reduce the waste of spiritual materials in the Pill Refinement process going forward.

After all, if one were refining ordinary medicine pills, they could certainly use Brother Fan's method to preserve the partially refined spiritual materials. This would not only greatly enhance the efficient use of spiritual materials but also increase the success rate of alchemy. It was a win-win situation. But why didn't the master teach it to them...

At this moment, the most shocked among everyone was the elder, also the master of the two children—Master Nanyang. When Master Nanyang heard Ding Fan's words and witnessed his actions, he was utterly astonished. After all, very few surpassed him in alchemy skills in the Donglai Continent.

But even he would never rely solely on the aroma emitted from the alchemy cauldron to determine the amount of spiritual material needed for restoring an ancient formula like the Eight Treasures Pill, not to mention using it correctly in a single try. This was simply unbelievable!

Master Nanyang clearly understood that probably no one else on Donglai Continent could achieve such precision. The elder knew even his longtime rival couldn't reach the level of this youth. Truly, heroes come from the young!

Initially, the elder was already very surprised that Ding Fan could determine the correct amount of spiritual material based solely on the aroma from the cauldron. But what he didn't expect was that Ding Fan also knew the method for preserving the cauldron, which was simply astonishing!

The elder knew that had he not seen it with his own eyes, he would never believe a mere youth could master the method for preserving the alchemy cauldron. Such a thing was nearly unbelievable. This preservation method was something he had only seen once from his own teacher.

He understood clearly that his teacher was not just anyone; even within the entire Cultivation World, few could rival his teacher's alchemy skills. His teacher also had a remarkable level of cultivation, which was something exceptionally rare among alchemists.

Usually, alchemists devoted their whole lives to studying medicine pills, which obviously detracted from their cultivation. Alchemists outshone ordinary cultivators and were highly respected in the Cultivation World, even if their cultivation level was not very high.

Even so, alchemists held a top position in the Cultivation World. Elder's teacher was a genius beyond peer, both in alchemy skill and cultivation level—a truly unique existence.

The elder realized that within the Cultivation World, someone like his teacher could likely only be his teacher. Perhaps in a few hundred years, someone of his teacher's caliber might not even appear.

The elder felt deeply regrettable that he never learned the method for preserving the alchemy cauldron from his teacher before his teacher passed away. This had remained a pain and regret in Master Nanyang's heart. He knew that even at his best, he might not equal his teacher's level. There were many things he hadn't learned before his teacher was gone.

Death is inevitable, and the elder had come to terms with it. After all, his teacher was alarmingly old and would one day pass.

Yet, witnessing the preservation method for the alchemy cauldron from Ding Fan, the elder couldn't help but be exhilarated. He realized that since his teacher's death, he thought this method had vanished. But today, not only did he see it again, but it was from the mouth of a young man. This was truly astonishing!

For a moment, the Elder couldn't help but feel a deep admiration for Ding Fan. Although the Elder was quite old, whenever it came to matters of alchemy, he would become very humble and eager to learn. The Elder then greeted Ding Fan with great respect:

"Young man, with such remarkable talent, how should I address you?"

At this moment, two young boys and girls saw their master showing great respect to Brother Fan, and couldn't help but feel extremely shocked. They had never seen their master speak to someone so humbly, especially to someone as young as Brother Fan.

It must be noted that their master was a highly renowned Alchemy Master on the Donglai Continent. Everyone who came to visit him was always very humble. When had they ever seen their master act like this, almost resembling a student meeting a teacher they admired? This left the two young boys and girls very surprised.

"Ding Fan."

At this moment, Ding Fan heard the Elder's words and realized that at some point, an Elder had appeared beside him. Clearly, he had been so focused on observing the alchemy process of the young man that he hadn't noticed someone had arrived. Upon hearing the Elder's inquiry, Ding Fan responded directly.

"Master, this is Brother Ding Fan. It was Brother Ding Fan and Sister He Qianyao who rescued us. We encountered some bad people in the front mountain..."

At this moment, the little girl began vividly recounting to the Elder how they encountered bad people and how Brother Ding Fan rescued them.

After hearing the little girl's story, the Elder affectionately patted the heads of the little girl and boy and said to them:

"You must be very careful when going out in the future. Do not casually discuss matters about medicine pills to avoid attracting attention from evildoers."

The Elder sternly warned the two young children, clearly a bit tense, feeling quite frightened after hearing his disciples' experiences. If anything had happened to his beloved disciples, he really wouldn't know what to do!

Subsequently, the Elder sincerely said to Ding Fan:

"Thank you, young man, for saving my disciples. I thank you in advance!"

"You're welcome! It was a small matter not worth mentioning!"

Upon hearing the Elder's words, Ding Fan responded with a calm smile, sincerely saying so.

"Qing Feng, quickly come and thank this young man!"

The Elder then looked at Ding Fan and instructed Qing Feng in the room directly, knowing well that without this young man's help, Qing Feng's pill refinement would not have recovered the two portions of materials so smoothly. Clearly, all the credit must go to this young man named Ding Fan.

Hearing the Elder's words, Qing Feng walked over to Ding Fan with utmost respect and said:

"Thank you, brother, for your assistance. Otherwise, I would not have smoothly determined the quantity of the two spiritual materials. Thank you, brother!"

With great sincerity, Qing Feng thanked Ding Fan.

"No need to be polite. I was merely curious and couldn't help myself when I saw you refining pills. Sorry about that."

With some embarrassment, Ding Fan said, evidently speaking the truth. His intention wasn't to help anyone in particular, but upon seeing someone engaged in pill refinement, especially when ancient techniques were being restored, he became interested and casually interjected. Yet, this turned out to be a tremendous help to Qing Feng.

It's important to know that Ding Fan's casual remarks saved Qing Feng at least two months. Given previous experiments, determining the correct amount of spiritual materials usually took several months. Most importantly, Ding Fan taught him how to preserve the alchemy cauldron.

The preservation method for the alchemy cauldron seemed unknown even to his master, yet Ding Fan shared it without any hesitation. This was an invaluable gift to Qing Feng!
