The dangerous zone within the Dark Forest.

To Guo Feilong, it's a treasure trove.

There are countless spirit herbs and spirit medicines.

As long as he confirms a certain area is safe,

he releases a large number of spiritual beasts

to search for spirit herbs and spirit medicines.

He groups the spiritual beasts in threes or twos, ensuring they don't stray too far from each other.

The relatively safe areas are those without fairies comparable to the Foundation Establishment stage, though there are still some comparable to the Qi Refining stage.

If a spiritual beast is alone, it might get ambushed and killed by a fairy.

After all, the physical strength of fairies is not inferior to spiritual beasts, and sometimes even stronger.

However, if three or two spiritual beasts are together, the fairies are more cautious and do not dare to ambush them.

All Ninth Rank spiritual beasts act alone; even if they encounter fairies, the fairies cannot easily ambush and kill them.

Thus, Guo Feilong's main task is to slay fairies comparable to the Qi Refining stage in certain areas,

while the dozens of spiritual beasts he brought search for spirit herbs and spirit medicines in relatively safe areas.

After killing other fairies comparable to the Qi Refining stage, Guo Feilong discovered that each fairy of this stage has three spirit stones inside them, all at least of medium quality.

Day by day passed like this, and in the blink of an eye, Guo Feilong had been in the dangerous zone of the Dark Forest for more than three months. He dared not venture into deeper, more dangerous areas, only searching along the edges for fairies comparable to the Qi Refining stage.

Over the course of more than three months, he killed a total of 48 fairies comparable to the Qi Refining stage, and gathered countless spirit herbs and spirit medicines, all stored in storage bags, piled up like mountains.

Fortunately, he brought a large number of storage bags this time, each one being a high-quality storage bag with ample internal storage space.

Otherwise, he wouldn't have been able to carry so much, especially since some fairies comparable to the Qi Refining stage have enormous bodies.

One of them, a stone fairy, was essentially a low mountain over a hundred meters tall, indistinguishable from a mountain when still.

Killing forty-eight fairies comparable to the Foundation Establishment stage yielded abundant materials for both alchemy and refinement, as their bodies provided high-quality materials.

During this time, Guo Feilong became obsessed with refinement, particularly with the Yellow Emperor's refinement legacy. Whenever he had free time, he studied and analyzed the properties of various refinement materials.

This book is hosted on another platform. Read the official version and support the author's work.

Especially a month ago, when he killed a metallic fairy and obtained a piece of silvery-white metal the size of two rooms.

Its strength reached the level of top-quality refinement material, and just two or three pounds could be used to craft a top-quality spiritual instrument.

That silvery-white metal, weighing at least two to three hundred thousand pounds, could be used to craft a hundred thousand top-quality flying swords.

This was comparable to the total output of a large top-quality spiritual instrument metal mine.

Most importantly, Guo Feilong discovered a unique property of this silvery-white metal: it could absorb other metals to enhance its quality.

Even though the soul consciousness of the silvery-white metal was killed by him, its ability to devour other metals for advancement remained.

He had never heard of such metal before. If it were refined into a spiritual instrument and provided with metals, it could potentially advance into a sacred treasure, or even higher.

Not only was this silvery-white metal rare, but half a month ago, he also killed a fairy comparable to the late Foundation Establishment stage, made of blood-red metal.

This blood-red metal, weighing thirty to forty thousand pounds, had self-repair capabilities, merging like mercury when damaged.

At that time, he exerted tremendous effort to kill this blood-red metal fairy, cutting it into dozens of pieces.

After storing the red metal fragments in a storage bag, he was surprised to find them fused into a single piece the next day when he opened the bag again.

These days,

Guo Feilong has been researching how to smelt the silvery-white metal with the red metal to create a new metal with both the ability to devour other metals and self-repair capabilities.

In this cultivation world, once a spiritual instrument or sacred treasure is crafted, if it gets damaged and shattered, it becomes useless scrap metal. Even if re-smelted into metal, it cannot become a spiritual instrument or sacred treasure again, only ordinary iron.

Guo Feilong is a man of action. These days, he hasn't gone looking for fairies comparable to the Qi Refining stage, but instead, in a cave he dug himself, he cuts the two metals into small pieces and attempts to fuse them in a refinement furnace.

He first melts the two small metal pieces into molten iron, thinking of mixing them together like pouring a bottle of blue ink and a bottle of red ink into a basin.

However, the result is that the two metals, like water and crude oil, cannot blend at all. When he stops using mystic power to stir, the two metal molten irons automatically separate to the left and right.

This method doesn't work.

He then heats the two metals red-hot and uses a blacksmith's method, repeatedly folding and hammering the two pieces.

After folding them hundreds of times, the result is like a mille-feuille, with each layer distinct and unable to become one.

"I refuse to believe I can't merge you two," Guo Feilong stubbornly muttered, staring at the two fist-sized metal pieces. Using the Yellow Emperor's refinement legacy, he unknowingly spent another seven or eight days researching.

On this day, it started raining outside the cave, with thunder rumbling. After days of research, Guo Feilong had an idea for merging the two metals but hesitated to try it.

Because if this method fails, he would lose two origin spirit beads comparable to the late Foundation Establishment stage fairies. These beads are much more valuable than those of the mid-Foundation Establishment stage.

One costs five million low-quality spirit stones, and two would be ten million low-quality spirit stones.

The loss wouldn't just be over ten million spirit stones, but also two powerful trump cards, as these could be refined into Spirit Explosion Beads with greater power.

The origin spirit beads of fairies comparable to the Foundation Establishment stage are expensive because they can be made into one-time explosive sacred treasures, Spirit Explosion Beads, capable of threatening Golden Elixir stage grand cultivators.

"Motherfucker, you can't catch a wolf without sacrificing a child. If I don't give up these two origin spirit beads, I won't get the new metal I want."

Gritting his teeth, Guo Feilong took out a red fairy origin spirit bead and a silvery-white fairy origin spirit bead from his storage bag.

These two spirit beads were the origin spirit beads inside the two metal fairies. Guo Feilong planned to grind these two origin spirit beads into powder, mix them, then melt the two metals into molten iron and mix everything together.

Without further ado, Guo Feilong began by grinding the two origin spirit beads into powder. Fairy origin spirit beads aren't hard, like pearls, they can be ground into powder.

Before long, the origin spirit beads of two fairies comparable to late Foundation Establishment stage cultivators produced a total of two piles of powder, one silver-white and one red.

Next, he placed the two types of powder in a larger porcelain bottle and used mystic power to stir them inside the bottle.

Soon, the two powders fused together.

Then, Guo Feilong began putting all the metal into the refinement furnace, melting it into molten iron, and quickly using mystic power to blend the two molten irons together.

If he stopped the fusion, the two metals would automatically separate. Guo Feilong poured all the powder made from the fairy origin spirit beads into the refinement furnace.

In the next instant, a miraculous scene unfolded. Under the influence of the origin spirit bead powder, the two metals burst into dazzling light and actively began to merge.

During the fusion of the two metal molten irons, Guo Feilong's divine sense could see the volume of the two molten irons shrinking.

Three days and nights later, Guo Feilong released a stream of mystic power, and the lid of the refinement furnace automatically opened. A head-sized, dark red metal emitting high heat flew out.

At this moment, the Artifact Spirit Little Cauldron in his mindscape suddenly spoke: "Master, quickly inject 3,000 auspicious clouds into this metal, and also drip a drop of your lifeblood essence.

Refine it into the shape of the item you desire, and it will become your lifebound sacred treasure. At the same time, this lifebound sacred treasure will also give birth to an artifact spirit."
