About the time it takes to drink a cup of tea later, the Fire Cloud Stone really began to change. The red Fire Cloud Stone gradually transformed into a liquid. Simultaneously, the rich Fire Element aura from the melted Fire Cloud Stone became apparent. Who could have thought that this would be the ultimate method to unlock the Fire Cloud Stone? This is perhaps one reason why the Fire Cloud Stone is not widely known.

Seeing this situation, a gleam appeared in Lin Feng’s eyes. All the effort was indeed worth it. The Fire Cloud Stone finally changed, and feeling the extremely rich Fire Element from it, a smile appeared on Lin Feng’s lips. He immediately enhanced the power of the Eternal Divine Flame.

In a flash, the Fire Cloud Stone began to melt at an even faster pace, turning into a pool of red liquid in the blink of an eye. Although this pool of red liquid was only the size of a fist, it emitted a terrifying Fire Element aura. Without the surrounding Eternal Divine Flame, this pool of red liquid might have been enough to ignite a city, showing how terrifying it has become.

"Master, this thing is amazing. The Fire Element aura on it makes me tremble, and it’s a pure Fire Element, which is exceptionally beneficial for me!" The Fire Spirit, Xiao Huo, suddenly appeared at this moment and shouted excitedly at Lin Feng, looking at the red liquid.

"It was originally prepared for you, now it’s up to you!" Lin Feng said calmly, looking at the Fire Spirit, Xiao Huo.

"Thank you, Master!" Hearing Lin Feng’s words, the Fire Spirit, Xiao Huo, immediately rushed towards the red liquid like a wolf that had seen meat, enveloping the red liquid almost instantly. The surrounding Eternal Divine Flame surged even more, seemingly about to collapse the already overwhelmed Alchemy Room!

Seeing this situation, Lin Feng felt a bit speechless. With a wave of his hand, a layer of Eternal Divine Flame appeared, immediately shielding the surroundings of the Alchemy Room. After doing this, he astonishingly saw that the pool of red liquid in mid-air had already been swallowed by the Fire Spirit, Xiao Huo. Subsequently, a pure red flame appeared in mid-air, and the Fire Spirit, Xiao Huo, suddenly disappeared!

"Xiao Huo?" Lin Feng immediately spoke out, really fearing that something might happen to the Fire Spirit, Xiao Huo.

"Master, I’m fine. I am integrating these Fire Elements. Once I digest these Fire Elements, I might evolve again!" The voice of the Fire Spirit, Xiao Huo, directly appeared in Lin Feng’s mind. Hearing these words, Lin Feng finally breathed a sigh of relief, no longer paying attention to the small, terrifying flame in mid-air.

Unable to perform alchemy at this time, Lin Feng closed his eyes out of boredom and began to deduce in his mind the alchemy process from Elder Chu’s prescriptions. As soon as the Fire Spirit, Xiao Huo, finished evolving, he could start the formal alchemy process.

Meanwhile, Tangyuan suddenly felt depressed. It had become like an ornament, wanting to make its presence felt with Lin Feng. However, seeing Lin Feng deep in thought, it refrained from disturbing him, sighed helplessly, and decided to nap on the ground instead.

Uncertain of how much time had passed, the pure red flame in mid-air suddenly changed, evolving into a kind of golden-red flame. The red glowed with a golden hue, and the gold carried a hint of red, looking extremely beautiful! The next moment, the golden-red flame swiftly flew to Lin Feng’s side, transforming back into its original form, Xiao Huo.

"Master, Xiao Huo succeeded!" The Fire Spirit, Xiao Huo, shouted excitedly at Lin Feng. It was now extremely happy, with its overall strength greatly improved. It could be said to have absorbed another Heaven and Earth Strange Fire. Curiously, it wondered what it would become if it continued to evolve in this way...

At this moment, Lin Feng opened his eyes, nodded with a smile, and then said to Xiao Huo: "Now, assist me in alchemy."

"Okay!" Receiving Lin Feng’s command, the Fire Spirit, Xiao Huo, immediately gathered up the rest of the Eternal Divine Flame in the Alchemy Room, then floated in front of Lin Feng, retracting all its flame power. If unaware, only a true Fire Spirit could achieve such a thing.

With everything ready, Lin Feng closed his eyes again and mentally rehearsed the process of refining the Earth Dragon Heart-Cleansing Pill. After confirming no issues with the refinement process, his Gang Qi erupted, and he placed the Haotian Cauldron on the ground, directing the Fire Spirit, Xiao Huo, to enter it.

As one spiritual herb after another was thrown into the Haotian Cauldron, a phenomenon appeared within it. Nine Flame Dragons spiraled on its walls, leaving Tangyuan dumbfounded, unable to fathom how such a change was occurring in the Medicinal Cauldron...

Amidst Tangyuan’s confusion, Lin Feng quickly placed all the spiritual herbs needed for refining the Earth Dragon Heart-Cleansing Pill into the Haotian Cauldron. Under the incomparable heat of the Eternal Divine Flame, all the spiritual herbs had their impurities burned away, forming droplets of elixir liquid that floated within the Haotian Cauldron.

The first step of purifying was completed at a speed no one could imagine.

Lin Feng wasn’t surprised by this step, as the control by the Fire Spirit, Xiao Huo was more than enough. His focus was on the second step: merging the elixir!

At this moment, different temperature zones had formed within the Haotian Cauldron, requiring temperature changes for the merging process. With this in mind, Lin Feng immediately instructed the Fire Spirit, Xiao Huo, to create an independent region for merging the elixirs. Following Lin Feng’s order, the Fire Spirit, Xiao Huo, carefully moved the suspended elixir droplets around and carved out a new, isolated temperature zone in the center of the Haotian Cauldron.

Once everything was in place, Lin Feng nodded. He then followed the directions on the Earth Dragon Heart-Cleansing Pill guide, using his Divine Sense to guide two of the many elixir liquids into the isolated temperature zone, beginning the first fusion.

The two types of elixir liquid rushed into the separate temperature zone at an indescribable speed, colliding and merging together. Immediately, the temperature in the separate zone began to rise, as if the two liquids were undergoing a chemical reaction. Seeing this, Lin Feng immediately said to Fire Spirit Xiao Huo, "Control the temperature, it must remain constant and not rise!"

Upon receiving Lin Feng’s command, Fire Spirit Xiao Huo immediately controlled the Ice Flame within the Eternal Divine Flame, lowering the surrounding temperature while also having to control the temperature around it, which made Fire Spirit Xiao Huo a bit frantic.

Fortunately, after just the time it takes to brew a cup of tea, the two types of elixir liquid had completely fused, forming a brand new elixir liquid, steadily floating in the center of the Haotian Cauldron.

Seeing the successful fusion, Lin Feng hesitated no more and immediately used his divine sense to urge another type of elixir liquid into the separate temperature zone to proceed with the next fusion step.

"Boom!"

"Control the temperature, slightly higher but no explosion!" 𝑓𝘳𝘦𝑒𝑤𝑒𝘣𝘯ℴ𝘷𝘦𝓁.𝑐𝑜𝑚

"Boom!"

"Maintain as it is now!"

...

With Lin Feng’s divine sense commanding, batch after batch of spiritual medicine elixir liquid continuously rushed to the center position, fusing with the previous batches of elixir liquid, following all the fusion steps recorded in the alchemy prescriptions, performing this extremely difficult fusion procedure.

Lin Feng’s divine sense was originally exceptionally strong, and combined with the assistance of Fire Spirit Xiao Huo, this process of alchemy was not too difficult for him. He seized the stable situation to continuously study the techniques recorded in Alchemist Dong’s alchemy book, pondering the differences between these alchemy techniques and Earth’s alchemy aspects, and why temperature needed to be controlled in such a manner, among many other details...

After an unknown amount of time, all the elixir was completely fused. At this moment, a golden elixir sphere appeared inside the Haotian Cauldron, floating like a legendary golden core, except this golden core was quite large, approximately the size of a soccer ball!

Seeing this, Lin Feng’s face broke into a smile, immediately proceeding to the third step, drawing the elixir!

From the alchemy prescriptions, this time the maximum amount of spiritual medicine could create up to Nine Pills, so Lin Feng had no hesitation in drawing the elixir this time. With a move of his divine sense, he immediately manipulated his Gang Qi to forcefully push the elixir liquid, causing it to rapidly circulate within the Haotian Cauldron, forming a long strip of elixir liquid. Seeing the timing, he decisively used Divine Consciousness Form Manifestation to divide the elixir into nine equal parts and simultaneously instructed Xiao Huo to separate these nine parts of elixir liquid, stabilizing them at the same temperature!

Yet at this moment, an unexpected incident occurred. After the nine portions of elixir were separated, they began to devour the Yuan Energy in the air voraciously, but there was limited Yuan Energy in the alchemy room. If this continued, it might not be enough to support the needs of these elixir liquids!

Faced with this situation, Lin Feng’s brow furrowed immediately, and without time to think too much, he quickly threw out nine Yuan Stones, swiftly setting up a Spirit Gathering Array in the alchemy room. Previously it gathered Spiritual Energy, but now it gathered Yuan Energy!

Once the Spirit Gathering Array was complete, the Yuan Energy in the air began to gather in the alchemy room. Though somewhat weak, it was barely adequate to support them. Meanwhile, Lin Feng also guided the Haotian Cauldron to absorb Yuan Energy, stabilizing the situation and preventing the entire batch of elixir from being ruined.

"Xiao Huo, roast quickly!"

With no time to deliberate further, Lin Feng promptly instructed Xiao Huo to roast, because if this continued, the Spirit Gathering Formation might not hold for much longer. After all, he only used nine Yuan Stones to set it up; he didn’t want this batch of elixir to be ruined!

"Understood, Master!" With Lin Feng’s command, Fire Spirit Xiao Huo immediately increased the temperature of the Eternal Divine Flame, starting the final process, roasting!

The temperature of the Eternal Divine Flame was terrifyingly high. Under full-force roasting, some impurities produced due to fusion began to be excluded, quickly converting into a solid state, while Lin Feng kept his eyes fixed on the nine segments of elixir, controlling the roasting process.

Soon, these nine portions of elixir transformed into the shape of pills, and at this moment, the absorption of Yuan Energy also slowed down, allowing Lin Feng to breathe a sigh of relief. When the elixir liquid was about to completely turn into solid pills, Lin Feng finally instructed Xiao Huo to adjust the temperature, slowly roasting with a gentle flame.
