Guo Feilong pondered the question for a moment, then decided to stop thinking about it. Anyway, when he encounters a fairy comparable to the Foundation Establishment stage again and kills it, he'll know.
This time, after killing two tree fairies equivalent to mid-Foundation Establishment, he used six Ninth Rank Sword Qi Talismans and one Swift Wind Talisman, totaling 750 auspicious clouds.
Enhancing his body to the level of a low-quality Sacred Treasure took another 50 auspicious clouds, making it a total of 800 auspicious clouds.
His children with spiritual roots, when they break through in cultivation, signify the family's growing strength, and the Family Fortune Cauldron will produce a certain amount of auspicious clouds.
When any of his children reach the first level of Qi Refining, the cauldron can produce 100 auspicious clouds at once.
At the second level of Qi Refining, it can produce 200 auspicious clouds.
At the third level of Qi Refining, it can produce 300 auspicious clouds.
And so on, until the ninth level of Qi Refining, when it can produce 900 auspicious clouds.
Currently, the highest cultivation level among his children is the third level of Qi Refining. The Artifact Spirit of the Family Fortune Cauldron, Little Cauldron, informed him that reaching the ninth level would yield 900 auspicious clouds.
If any of his children manage to reach the Foundation Establishment stage in the future, the cauldron will produce even more auspicious clouds.
The wood bodies of the two tree fairies, equivalent to mid-Foundation Establishment, are comparable to high-quality spiritual instruments and are materials for making high-quality spiritual instruments. One is worth a million low-quality spirit stones, and two are worth two million low-quality spirit stones.
After all, killing a fairy equivalent to mid-Foundation Establishment is much harder than killing a mid-Foundation Establishment cultivator.
A medium-quality spirit stone is worth 50,000 low-quality spirit stones.
The total value of six spirit stones is 750,000 low-quality spirit stones.
However, the most valuable items are the two source beads equivalent to the Foundation Establishment stage, each worth at least 1.5 million low-quality spirit stones.
The reason they are so expensive is that the one-time explosive Sacred Treasures made from them have immense power and can even pose a threat to Golden Elixir stage grand cultivators. How could they not be expensive?
Moreover, obtaining source beads from spiritual objects equivalent to the Foundation Establishment stage is extremely difficult.
Cultivators beyond the Qi Refining stage cannot enter the Dark Forest.
Those at the Qi Refining stage do not dare to seek out spiritual objects equivalent to the Foundation Establishment stage.
Unauthorized tale usage: if you spot this story on Amazon, report the violation.
Otherwise, it would be like an old man eating arsenic, courting death!
Of course, outside the Dark Forest's Small World, in other higher-level Small Worlds, Foundation Establishment stage cultivators can enter.
But higher-level Small Worlds are also more dangerous, and Foundation Establishment stage cultivators can become prey for spiritual objects and die inside.
The value of the two fairy source beads is three million low-quality spirit stones. Guo Feilong calculated that the total value of killing two tree fairies equivalent to mid-Foundation Establishment is about 6.25 million low-quality spirit stones.
However, whether it's the source beads inside the fairies or the spirit stones, they are scarce resources with a price but no market. You can't buy them just because you have money. Acquiring them is a matter of fate and opportunity.
Guo Feilong has no intention of selling the two fairy source beads, which can be made into one-time explosive Sacred Treasures that can pose a threat to Golden Elixir stage grand cultivators.
Since receiving the Yellow Emperor's legacy from the Artifact Spirit Little Cauldron, Guo Feilong has also achieved considerable success in the art of refining.
Most of the spiritual instruments his wives use were personally crafted by him.
A moment later, Guo Feilong saw the foot of a low hill. He patted his Storage Bag, and a top-quality spiritual instrument flying sword flew out.
Under his control, the flying sword cut through the hillside like tofu, and rubble fell from the mountain.
In just over half an hour, Guo Feilong had carved out a cave in the low hill.
The cave corridor was one and a half meters wide and two meters high, with a circular hall at the end five meters high and ten meters in diameter.

Guo Feilong released a high-quality refining furnace from his Storage Bag, placing it steadily on the ground. He intended to refine the two fairy source beads into one-time explosive treasures.
The more life-saving trump cards, the better.
He placed several fire stones at the bottom of the refining furnace, and a roaring fire filled the stone chamber with intense heat.
Although it was his first time refining fairy source beads, Guo Feilong knew how to make them into one-time explosive Sacred Treasures. During his hundred years as an Outer Disciple at the Spirit Creek Sect, he enjoyed reading whenever he had free time.
He read every book he was allowed to in the Spirit Creek Sect's library, including those on alchemy, refining, and talisman creation.
Making fairy source beads into one-time explosive Sacred Treasures isn't difficult; the challenge lies in obtaining the fairy source beads, much like learning to shoot a gun isn't hard, but acquiring a gun is.
Though not difficult, refining isn't easy either. It took him about thirteen or fourteen hours, consuming most of his mystic power, to refine the thunder attribute fairy source bead into a one-time explosive Sacred Treasure.
As for its power?
He wasn't sure.
But it was undoubtedly immense.
If he infused it with auspicious clouds to enhance its power, it could increase several times, tenfold, or even dozens of times.
In a surprise attack, it might even kill a Golden Elixir stage grand cultivator.
The thought excited Guo Feilong so much that his body trembled.
Even if one couldn't kill a Golden Elixir stage grand cultivator, what about two, three, or even dozens or hundreds?
He believed that with enough quantity, he could certainly kill a Golden Elixir stage grand cultivator.
However, doing so would consume a lot of auspicious clouds.
"When I return, I must marry more female cultivators with spiritual roots and have more children, producing more children with spiritual roots."
Guo Feilong resolved.
He held the refined thunder attribute fairy source bead in his hand, which had its own name after refinement.
It was called a Spirit Explosion Bead.
Meaning a one-time explosive Sacred Treasure made from a fairy source bead with great power.
He released the Ninth Rank spiritual beast, Treasure-Seeking Mink Xiaobai, from the Spiritual Beast Bag to stand guard.
Guo Feilong took out many low-quality spirit stones, sat on them, and began cultivating to restore his mystic power.
About two hours later, his cultivation ended, and his mystic power was fully restored.
He tossed a few strips of beef jerky to the Ninth Rank spiritual beast, Treasure-Seeking Mink Xiaobai, and took out the wood attribute fairy source bead from the Storage Bag, placing it into the refining furnace to start refining the second Spirit Explosion Bead.
With the experience from the first Spirit Explosion Bead, the second one took less than ten hours to refine, nearly a third faster, and even saved about a fifth of his mystic power.
Of course, to ensure success, he used some auspicious clouds during the refinement of the two Spirit Explosion Beads.
These two Spirit Explosion Beads were undoubtedly his most powerful trump cards, and he wouldn't use them unless in a life-or-death situation.
After meditating to restore his mystic power, Guo Feilong left the cave and released several land spiritual beasts from the Storage Bag, instructing them to search for spirit herbs and spirit medicines nearby.
Whether human, spiritual beast, or fairy, they all have their territories.
Having killed two tree fairies equivalent to mid-Foundation Establishment, the area was temporarily safe, with no other fairies of that level around.
The released land spiritual beasts didn't disappoint, gradually bringing back spirit herbs and spirit medicines, including five Sixth Grade spirit herbs and more than ten Fifth Grade spirit medicines.
Guo Feilong wasn't in a hurry to leave, allowing the spiritual beasts to search the surrounding area for three days and nights, finding many spirit herbs and spirit medicines. He then ventured deeper into the Dark Forest.
