On the path to immortality, I can see destiny.

The moment the furnace lid was opened, a rich medicinal aroma poured out as if it were a tangible substance, instantly filling the entire alchemy room.

Ten pills, each the size of a longan and with a bluish-green color, were spat out from the mouth of the Azure Dragon and lay quietly in Zhao Fan's hand, emitting a calming, herbal fragrance.

"Ten Rejuvenation Pills are all of inferior quality."

Zhao Fan spoke calmly, placing the jade plate aside.

"Ten pills made is not bad. But the art of alchemy is not just about the number of pills made, but also about the understanding and control of each step."

"What I just demonstrated was the most basic method for refining the Rejuvenation Pill. Did you all see it clearly?"

The three children were already stunned. They were nodding frantically, their eyes filled with excitement and a strong desire to try it out.

"Now that you've seen it clearly, it's time to do it yourself. Let's start with Zichen, one person at a time, and the others can watch from the sidelines."

He paused, then emphasized his words.

"Remember what I just said: when handling medicinal herbs, you must be meticulous and careful, calm your mind, and not panic."

"When you are refining and condensing the pills, do not be greedy. Failure is common, but you must understand why. I will be watching from the side. If you have any questions after refining the pills, you can ask me."

"You must have seen the mystic runes I just used. These are for controlling the heat, and they are the most important to you."

After listening to Zhao Fan's words, Su Zichen took a deep breath and bowed first.

"Yes, Brother Zhao!"

With a solemn expression, he walked toward the alchemy furnace.

Su Zihuan and Su Ziyun quickly followed, cheering them on from the sidelines.

The atmosphere in the alchemy room suddenly became tense and focused.

The faint sounds of cutting medicinal herbs rang out again, but they were far more clumsy and chaotic than when Zhao Fan had demonstrated it.

Su Zichen was the most composed. He recalled Zhao Fan's every move, picked up the Vitality Grass, and carefully controlled the Xuanwen.

However, if the spiritual energy was injected unevenly, one of the medicinal herbs burst into flames and turned to ashes in the blink of an eye.

"Oh no!"

His heart tightened, and he immediately became flustered. As a result, the remaining medicinal herbs were also lost and were all burned by the raging flames.

Su Zichen looked at the ashes at the bottom of the medicine furnace and silently shook his head.

He then looked up at Zhao Fan and gave an awkward smile.

"Brother Zhao, I'm sorry, I failed."

Zhao Fan did not criticize him, but gently comforted him.

"It's alright. No one succeeds at first. I failed many times too."

With Zhao Fan's comfort, Su Zichen felt much better.

Next, it's Su Ziheng's turn.

Su Zihuan was a bit impatient, and seeing that his elder brother was moving slowly, he wanted to be faster.

Before they could even figure out the effects of the mystical runes, they threw the medicinal herbs into the cauldron. As a result, the largest flame appeared immediately, burning all the spiritual herbs to ashes.

Seeing this scene, Zhao Fan frowned deeply. When Su Ziheng came down, Zhao Fan couldn't help but scold him angrily.

"What are you so anxious about? These medicinal herbs, though not expensive, are still worth a spirit stone, and you just burned them for no reason."

Knowing he was in the wrong, Su Ziheng could only lower his head and remain silent.

Soon, it was Su Ziyun's turn.

She first laid out all the medicinal herbs in front of her, then closed her eyes and recalled Zhao Fan's alchemy process.

Then, imitating Zhao Fan, he activated the Xuanwen (mysterious runes), and only after mastering the furnace temperature did he put the medicinal herbs into it.

Among the three, Su Ziyun had the lowest cultivation level, only at the second level of Qi Refining, and her spiritual sense was limited.

It was clearly insufficient to process seven kinds of medicinal materials at the same time.

Although the control over the heat was not bad, due to insufficient spiritual power, it ultimately failed and only produced a blob of waste liquid.

In the end, although he barely managed to complete the pill-condensing process, it turned out to be a black, useless pill.

Although Su Ziyun also failed, her performance surprised Zhao Fan.

Su Ziyun failed because her cultivation level was insufficient, but in terms of skill alone, she was clearly superior to the other two.

Seeing Su Ziyun's disappointed expression, Zhao Fan continued to comfort her.

"It's alright, Ziyun, you've done very well. I'll teach you another profound rune in a bit, which will solve your problem of insufficient spiritual sense."

Upon hearing this, Su Ziyun's face lit up with surprise, and she nodded emphatically.

Next, it was Su Zichen's turn to refine pills.

The two people next to them, although they didn't participate themselves, were watching very attentively.

Su Zichen kept a close eye on the fire in the stove, carefully controlling the temperature.

He remembered Zhao Fan saying that the Rejuvenation Pill needed to be heated slowly, so he carefully put a portion of the prepared blood-clotting flower into what he considered to be the area with the lowest temperature.

As a result, it backfired.

Because different medicinal materials require different temperatures, some melt into a medicinal liquid while others do not, resulting in a messy and ineffective process, ruining the entire medicinal material preparation.

As for Su Zihuan behind him, he spotted an area with a stable flame and threw several medicinal herbs into it all at once.

"Let's integrate first!"

He muttered to himself, increasing his spiritual energy output in an attempt to make the flames burn brighter and speed up the fusion process.

As a result, the conflicting properties of various medicinal materials caused them to churn violently under the sudden increase in heat, ultimately turning them into a pile of ashes.

After Su Ziyun took over, Zhao Fan taught her to use one of the profound runes to temporarily preserve the already melted medicinal herbs, thus avoiding the weakness of her divine sense.

She first placed her hand lightly above the observation port of the alchemy furnace, closed her eyes, and carefully felt the temperature and fluctuations of the flames in different positions inside the furnace for a moment.

Then, she first put a medicinal herb into a suitable area to dissolve it into a medicinal liquid.

Then came another medicinal herb.

In the blink of an eye, all seven medicinal herbs had been melted down.

However, a mistake was made during the subsequent fusion of the medicinal liquids, and the attempt ultimately failed.

After that, the three of them took turns refining pills, and each of them made progress. However, Su Zichen and Su Ziheng never reached the point of successfully refining pills.

Only Su Ziyun could make the medicinal liquid blend together. Although the color was not as pure and blue as when Zhao Fan refined it, it still presented a fairly uniform light green.

"You two are a mix of unrealistic ambitions and overly cautious behavior. You should learn more from Ziyun."

Zhao Fan watched as Su Ziyun was about to complete her cultivation, then looked at the two of them and spoke softly.

The two responded hesitantly, looking dejected.

Zhao Fan finally walked to Su Ziyun's side, but did not make a sound to disturb her; he simply watched her quietly.

At this moment, the medicinal liquids have been fully mixed, and the most crucial moment of separating the pills has arrived.

Su Ziyun took a deep breath, recalling the smooth and precise spiritual energy trajectory when Zhao Fan activated the main furnace's core-dividing runes.

Her cultivation was still shallow, and she could not drive the complex combination of mystic patterns. She could only rely on her meager divine sense and spiritual power to barely guide the basic formation in the furnace to generate weak spiritual threads.

With a subtle spiritual light emanating from her fingertips, she quickly touched a specific area of ​​the alchemy furnace, her small face full of focus.

Inside the furnace, several pale green spiritual threads, thinner than a hair and almost invisible, struggled to emerge, trembling as they reached for the pale green liquid.
