Chapter 81

Lin Feng carefully observed the alchemical furnace in front of him. It had three legs, a pointed top, and a completely black body. The furnace was engraved with faint patterns, but it was now covered in dust, clearly unused for a long time.

Lin Feng infused his magical power into it, but the furnace showed no reaction. He put some medicinal herbs inside, but there was still no response.

"Indeed, it's strange." Lin Feng scratched his head. No wonder the furnace looked so old and unused, appearing to be nothing more than a worthless piece of junk.

But Lin Feng did not doubt Zhu Yi's luck. He entered the exchange system and began to search through the list item by item.

The strange patterns on the furnace could serve as an important identifier.

His efforts paid off, and Lin Feng found a furnace almost at the bottom of the list, with features very similar to the one he had.

The Heavenly Heart Fire Furnace, made from meteoric iron, generates heart fire during alchemy, adding a powerful flame, thus greatly increasing the success rate of alchemy.

The required exchange points... 3000 points!

Lin Feng slapped his forehead, wishing he could immediately go to the next room and hug Zhu Yi.

3000 points, he couldn't even gather that many points if he sold himself.

From the time the system was activated until now, including the beginner's package, Lin Feng had accumulated a total of only 2800 points.

The 700 points Lin Feng currently had were only enough to buy one leg of the Heavenly Heart Fire Furnace.

"Great, truly great!" Lin Feng was overjoyed, but then a question arose in his mind.

If this furnace is so good, why hasn't anyone discovered it?

One or two people might not have discovered the secrets of the furnace, but all the people who handled it?

With this question in mind, Lin Feng carefully checked the information about the Heavenly Heart Fire Furnace and found a note: "Only the seven true fires can bring out the full potential of the Heavenly Heart Fire Furnace."

Lin Feng blinked, a bitter taste in his mouth, finally understanding why others couldn't discover the furnace's wonders.

The seven true fires, the pinnacle of fire power in this world, each can infinitely enhance its power, being tyrannical and capable of destroying heaven and earth. How easy is it to obtain their fire seeds?

Lin Feng pressed his temples, telling himself to calm down, and carefully studied the information about the Heavenly Heart Fire Furnace.

"Bring out the full potential... that means, a slightly lower level of spiritual fire can also make the furnace work, but it won't bring out its full potential." Lin Feng began to understand: "The higher the level of the spiritual fire, the more obvious the effect. If the spiritual fire is too low, it won't be able to activate the furnace."

With this in mind, Lin Feng felt more at ease.

The Immovable King's Wrath Fire is widely recognized as the second-highest level of spiritual fire after the seven true fires.

Lin Feng immediately set up the Twenty-Four Heavenly Arhats Formation, then, following the previous method, used three flame arhats as the core to condense the Immovable King's Wrath Fire.

A milky white flame fell into the Heavenly Heart Fire Furnace, and the furnace immediately changed.

It was as if a giant that had been asleep for a long time finally awoke.

Around the milky white Immovable King's Wrath Fire, a bright red flame "popped" up, jumping like a strong, beating heart.

As this "heart" beat, fiery red patterns appeared on the inner walls of the furnace.

At this moment, the originally palm-sized Heavenly Heart Fire Furnace rapidly grew, reaching two meters in height and nearly two meters in diameter before stopping, firmly landing on the ground, emitting a powerful magical power fluctuation.

Lin Feng smiled: "That red flame that looks like a heart should be the so-called heart fire. Hmm... truly remarkable, its burning power is not much different from the Immovable King's Wrath Fire."

Cultivators skilled in alchemy often practice fire-based techniques, using their own magical power and true fire to transform into alchemical fire to refine medicinal pills.

Lin Feng practiced the Immovable King's Wrath Technique, so he had the alchemical fire, but he had never refined a pill before, and he was somewhat anxious.

Putting the medicinal herbs for the Thunder Sound Great Rejuvenation Pill into the furnace, Lin Feng began to carefully control the alchemical fire.

Sometimes, one must admit, learning something indeed depends on talent.

Lin Feng worked hard, but after a long time, when he opened the furnace to take out the pills, all he saw was a furnace full of charcoal.

"Was the fire too strong? Or was the combination of herbs wrong?" Lin Feng scratched his head in frustration. He still had plenty of herbs, but he couldn't keep using them for practice.

After frowning and thinking for a moment, a flash of inspiration suddenly appeared in Lin Feng's mind.

"Come to my room, all of you, and bring your eldest brother along." Lin Feng calmly sent a message to Zhu Yi and the others in the next room, then sat cross-legged, waiting for his disciples to arrive.

Little Point was the first to push the door open, looking at Lin Feng and the Heavenly Heart Fire Furnace that almost touched the ceiling with a puzzled expression.

Behind him, Zhu Yi and Wang Lin carried a stretcher into the room, with Xiao Yan lying on it, pale-faced but in relatively good spirits.

"Disciples greet Master." The four said together, with Xiao Yan lying down and the other three bowing.

Lin Feng nodded slightly and said, "Have you all seen the furnace in front of you?"

The four nodded, and Zhu Yi asked, "Master, is this the furnace we saw in the market?"

Lin Feng smiled slightly, "This furnace is called the Heavenly Heart Fire Furnace, with countless wonders. Unfortunately, it was like a pearl hidden in the dust. Now, I have reactivated it, revealing its true form."

Zhu Yi marveled, "Truly a remarkable object."

Little Point then asked, "Master, did you call us here just to see the furnace?"

Lin Feng shook his head and replied, "No, I called you here to test you."

Test us?

The four looked at each other, and Xiao Yan, lying on the stretcher, said softly, "What test, please instruct us, Master."

Lin Feng pointed to the Heavenly Heart Fire Furnace and said casually, "To treat Xiao Yan's injuries, I am currently refining a medicinal pill. However, I intentionally made a few mistakes. If we refine it this way, it will definitely fail."

"I want to test your talent and intuition in alchemy, to see if you can spot the mistakes I intentionally left." Lin Feng said seriously, handing them the formula for the Thunder Sound Great Rejuvenation Pill and explaining the functions of the Heavenly Heart Fire Furnace in detail.

"Am I being too despicable? Just average..." Lin Feng thought to himself, maintaining a dignified expression and saying calmly, "You can discuss among yourselves. I will listen from the side and keep track of who provides the correct insights."

The four looked at each other and gathered around Xiao Yan's stretcher, leaning in to discuss.

Lin Feng secretly listened to their discussion, comparing it with his own insights, and gained much from it.

It must be said, the system's judgment was very accurate. Among the four, Xiao Yan was the quickest to grasp and understand alchemy, finding the most and fastest the mistakes in Lin Feng's original method.

Whether they were accurate still needed to be verified.

In the end, the other three also chose Xiao Yan to summarize their findings.

"…The Heavenly Bone Grass cannot be placed whole into the furnace; it must be ground into powder first. The Frost Dew and Green Fire Phosphorus Grass must be mixed together before being placed into the furnace, not separately." Xiao Yan summarized, hesitating for a moment before adding, "Also, I think the furnace should be opened half an hour earlier, but I'm not sure about this."

Lin Feng remained calm and composed, and after Xiao Yan finished, he looked at the other three and asked, "Do you have anything to add?"

The other three shook their heads, and Lin Feng smiled, "All done, no changes?"

Xiao Yan gritted his teeth, "No changes."

Lin Feng stood up and smiled, "I won't comment much. Let's let the facts speak. We will refine a batch of pills using your method and see the results." He then followed Xiao Yan's instructions to process the herbs and start the alchemy.

Lin Feng controlled the furnace fire, and the four disciples watched the furnace closely, with Xiao Yan particularly nervous, his palms sweating.

The four did not know that Lin Feng was even more nervous, staring at the furnace: "Brat, you must do well."
