When this stone fairy remains still, it appears just like an ordinary stone, even Guo Feilong didn't notice it, which shows how well these fairies in the Dark Forest can hide themselves.

Guo Feilong was at the tenth level of Qi Refining, while the aura emanating from the stone fairy that suddenly attacked him was only equivalent to the sixth level of Qi Refining.

However, the stone body of this stone fairy was comparable to a low-quality spiritual instrument, essentially a humanoid stone weapon.

Bang!

A layer of golden light appeared on Guo Feilong's skin as he punched the stone axe coming at him with his bare hands, his body comparable to a top-quality spiritual instrument.

In this collision, his fist was unharmed, but the stone axe of the opponent was left with a large notch, demonstrating the damage a top-quality spiritual instrument can inflict on a low-quality one.

Swish!

Guo Feilong's figure flickered, appearing in front of the stone fairy, and his fist, as strong as a top-quality spiritual instrument, struck the opponent's head fiercely.

With two consecutive punches, the stone fairy's head shattered with a bang, but the stone fairy did not die.

A flash of earthy yellow light appeared on the stone fairy, and a new stone head grew from its neck. Knowing it couldn't win, it immediately turned to flee.

How could Guo Feilong let it escape? He chased after it, and with a few punches, turned the stone fairy into a pile of rubble.

A round, egg-sized earthy yellow crystal, emitting a faint earthy yellow light, stood out in the pile of rubble.

The first fairy he killed had a spiritual object; his luck was indeed very good.

With a wave of his hand, the earthy yellow spirit stone flew into Guo Feilong's palm.

This was a low-quality earth attribute spiritual object spirit stone, with a market price of 5,000 low-quality spirit stones.

Gathering ten such low-quality earth attribute spiritual objects equates to one medium-quality earth attribute spiritual object, which can allow a cultivator's Foundation Establishment platform to reach a medium quality level.

No amount of low-quality spiritual objects can allow a cultivator to form a high-quality or top-quality Foundation Establishment platform.

Only ten medium-quality spiritual objects can form a high-quality Foundation Establishment platform.

Ten high-quality spiritual objects can form a top-quality Foundation Establishment platform.

As for ten top-quality spiritual objects, they can still only form a top-quality Foundation Establishment platform, no matter how many are used.

It's like a cup that can only hold 1000 milliliters of water; it can't hold more.

A top-quality Foundation Establishment platform is the pinnacle, the highest level that cannot be surpassed.

The story has been stolen; if detected on Amazon, report the violation.

Fairies cannot be enslaved like spiritual beasts with a Beast Command Token. Besides the spiritual object crystals within them, their corpses can also be useful after they die.

Some can be used as spirit herbs and medicines since they originally gained intelligence and cultivated from spirit herbs and medicines.

Some can become materials for refining spiritual instruments and sacred treasures, like the stone fairy he killed; the rubble could be taken back and smelted into metal.

Killing a fairy, regardless of whether it contains a spiritual object spirit stone, is always profitable.

However, their most valuable part is the spiritual object crystal within them; the rest is not as valuable.

Guo Feilong collected the rubble of the stone fairy, put it into his storage bag, and continued deeper into the Heavenly Abode of the Dark Forest on the back of Erha.

The deeper he went into the Dark Forest, the higher the chance of encountering fairies. If unlucky, one might even encounter fairies comparable to the Foundation Establishment stage.

The higher the level of the fairy, the higher the grade of the spiritual object crystal within them, and the greater the danger.

In the blink of an eye, another five days passed, and Guo Feilong had been in the Dark Forest for thirteen days. During these thirteen days, he encountered seven fairies, but only the first stone fairy he killed produced a low-quality spiritual object crystal.

The Ninth Rank Treasure-Seeking Mink, Xiaobai, found more spirit medicines each day, including a Sixth Grade Nine Aperture Blood Spirit Plant, an excellent material for refining healing medicines, valued at over 100,000 spirit stones.

He also encountered several groups of cultivators, ranging from over twenty people to as few as five or six.

They were not all ninth-level Qi Refining cultivators; many were low-level cultivators banding together for safety, as it was the only way to be safer in the Dark Forest.

Guo Feilong, traveling alone with two Ninth Rank spiritual beasts, was not bothered by these cultivators, who, despite their numbers, dared not provoke him and would take a detour upon encountering him.

Without much trouble along the way, Guo Feilong reached the dangerous area of the Dark Forest, where fairies comparable to the Foundation Establishment stage appeared.

Ordinary Qi Refining stage cultivators would not proceed further here, as they couldn't defeat fairies comparable to Foundation Establishment stage cultivators.

But Guo Feilong was different; unless he encountered fairies comparable to the late Foundation Establishment stage or Great Perfection, he was confident in defeating any fairy comparable to the early or mid Foundation Establishment stage, especially with the surprisingly powerful Ninth Grade talisman enhanced by auspicious clouds.

Moreover, he could elevate the Golden Body Technique to make his body comparable to medium or high-quality sacred treasures.

Even a Golden Elixir stage great cultivator couldn't kill him with a single slap.

As the saying goes, "Man dies for wealth, birds die for food."

Some Qi Refining stage cultivators risked entering the dangerous area, betting they wouldn't encounter fairies comparable to the Foundation Establishment stage, to search for spirit herbs and low-level fairies.

Of these people, seven or eight out of ten would die in the dangerous area.

The two or three who survived would indeed gain a fortune in spirit herbs and medicines.

On the second day of entering the dangerous area of the Dark Forest, the Ninth Rank Ice Flame Hound, Erha, suddenly barked softly, "Master, there's a battle fluctuation coming from ten miles ahead."

The ears, nose, and spiritual energy perception of spiritual beasts are many times that of humans. What Guo Feilong couldn't sense, Erha could.

"Let's go and take a look," Guo Feilong said, holding several Ninth Rank talismans, both defensive and offensive.

The reason he wanted to go was because of his strength.

Without strength, one must be cautious.

With strength, one can be low-key and unassuming.

But being low-key doesn't mean being afraid of trouble.

Soon, Guo Feilong could feel the mystic power fluctuations and sounds of battle ahead.

Judging from the mystic power fluctuations and sounds, it was not something that could be caused by the Qi Refining stage; it should be two fairies comparable to the Foundation Establishment stage fighting.

As he got closer, Guo Feilong finally saw the two combatants.

One was a tree fairy, thirty meters tall, with a trunk so thick it took seven or eight people to encircle it.

The trunk had a nose, mouth, eyes, and ears, and its branches formed human-like hands, with roots moving quickly along the ground.

It spat green light from its mouth, transforming into sharp-tipped logs to attack its opponent.

Its opponent was also a tree fairy, but of a different species, entirely purple with lightning power crackling around it, emitting a crisp, weak, and dense crackling sound, spitting out one thunderball after another.

These two different species of tree fairies, fiercely fighting, were both comparable to mid Foundation Establishment stage cultivators.

Guo Feilong put the Ninth Rank spiritual beasts, Xiaobai and Erha, into the Spiritual Beast Bag, fearing their large sizes would attract the attention of the two tree fairies.

In front of tree fairies comparable to mid Foundation Establishment stage cultivators, Ninth Rank spiritual beasts were like toddlers, easily killed with a slap.

"Wang Yuyan is of the thunder attribute, and Sun Yufeng is of the wood attribute, perfectly matching the attributes of these two tree fairies. I hope both tree fairies have spiritual object crystals inside."

Guo Feilong hid behind a large tree, eyes fixed on the fighting tree fairies, calculating the best moment to strike.

Moments later, the two tree fairies, with little mystic power left, engaged in fierce physical combat.

Their branch-formed hands slapped each other like a brawl.

The bodies of these two tree fairies, comparable to mid Foundation Establishment stage cultivators, were as strong as high-quality spiritual instruments. If they had enough mystic power, their bodies could reach top-quality spiritual instrument levels.

After about half an hour, the two tree fairies were exhausted, their strikes as weak as if they hadn't eaten.

Now was the perfect time for a sneak attack. Guo Feilong held a Ninth Rank Sword Qi Talisman in each hand, injecting 100 auspicious clouds into each, and threw them at the two tree fairies.

Boom!

Boom!

The two Ninth Rank Sword Qi Talismans transformed into hundred-meter-long Sword Qi, slashing down from the sky.

The two tree fairies, exhausted from fighting, hurriedly used their branch-formed hands to block in front of them.
