The secret path wasn't long. Fang Yuan and Bai Ning Bing walked for a while and soon arrived at a spacious hall.
The pure white hall was made entirely of bones. In the center of the hall was a large vat.
The vat was full of a white liquid that looked like milk, emitting a fragrant scent.
Fang Yuan approached the vat, and the related memories involuntarily surfaced.
According to what Bai Hua said in his past life, the bottom of this vat should be connected to a spring.
This spring was the Milk Spring.
The spring water was like milk, with a sweet and refreshing taste. It wasn't just an excellent drink; it was also rich in nutrients. Children who drank it grew well, and elders who drank it became strong and healthy.
The Milk Spring was a specialty of White Bone Mountain.
In his past life, after the Hundred Families migrated here, they developed five Milk Springs. The Milk Spring became a specialty of the Hundred Families. They not only supplied themselves but also traded it as a commodity. Every year, many merchant caravans would come to trade.
"There are Gu in this vat…" Fang Yuan said, motioning with his eyes toward Bai Ning Bing.
Although according to his memories this place was perfectly safe, Fang Yuan was naturally cautious. After all, this wasn't his own personal experience; the information was all hearsay.
It was better to let someone else handle risky matters.
Bai Ning Bing snorted coldly. Activating her defenses, she reached her hand into the vat.
"There are so many Gu inside!" Soon, her eyebrows shot up, and she revealed a surprised expression.
When she pulled her hand back, her hand was already full of Gu worms.
These Gu were the size of an average person's index finger, completely white in color. One end was round, and the other was sharp, like a miniature spear.
This was the Bone Spear Gu.
"Although this Gu is Rank 1, there's just so many of them. This vat is almost completely filled with this Gu worm," Bai Ning Bing said, a little excitedly.
The Bone Spear Gu was similar to the Moonblade Gu of Gu Yue Village. It was a basic item of this Bone Path inheritance.
In his past life, after the Hundred Families discovered this inheritance, a large number of Gu Masters in the clan were equipped with this Gu. The Bone Spear Gu also became a trademark of the Hundred Families' Gu Masters.
"Search again. There should be Rank 2 Gu in this vat," Fang Yuan said, standing by with a calm expression.
Bai Ning Bing fished a few times and finally found a Rank 2 Gu.
This Gu was similar to the Bone Spear Gu, but on the surface of the bone spear were spiral carvings — the Spiral Bone Spear Gu.
This Gu was an improved version of the Bone Spear Gu. When shot out, its attack power was higher, and compared to the direct shot of the Bone Spear Gu, it had an extra drilling force.
In the vat, Bone Spear Gu made up the vast majority, with only a small number of Spiral Bone Spears.
"At this rate, I finally have a conventional and stable means of attack," Fang Yuan pinched a Spiral Bone Spear Gu and thought to himself.
The Lightning Potato Gu was very unstable. It had to be planted in the ground. If no one stepped on it, it was a total waste. If a Gu Master had a bad memory and forgot where they planted their Lightning Potato Gu, they might even hurt themselves.
Furthermore, the use of the Lightning Potato Gu had restrictions. It had to be used in soil, and the more fertile the land, the better. As for special places like White Bone Mountain, the Lightning Potato Gu couldn't be used. Otherwise, Fang Yuan wouldn't have minded setting up another one or two traps.
"It's a pity there are no Rank 3 Gu," Bai Ning Bing said with some regret. She picked a Spiral Bone Spear Gu and tucked it into her pocket, intending to refine it later.
However, this kind of Rank 2 Gu was merely a novelty to her. Using it in actual combat would not allow her to display the strength of a Rank 3 Gu Master.
Seeing that there was absolutely no danger in the vat, Fang Yuan began to act.
He scooped out the Gu worms handful after handful. Relying on the aura of the Spring Autumn Cicada, he frantically spewed out his true essence, refining them in an instant.
"You… what are you…" Bai Ning Bing was dumbfounded.
In a short span of time, Fang Yuan had already refined dozens of Gu worms, and he was still going!
Because of the Spring Autumn Cicada, he could instantly refine them. And because of his aptitude and the Heaven Essence Lotus, the recovery speed of his true essence was greater than the consumption speed of refining, allowing him to keep going without stopping.
This was like a crazy performance!
Fang Yuan's aperture now had two hundred Bone Spear Gu and over twenty Spiral Bone Spear Gu.
Refining Gu had always been a major bottleneck for Gu Masters. Although Bai Ning Bing had seen Fang Yuan instantly refine Gu worms a few times, this time was the most visually impactful.
In Fang Yuan's hands, refining Gu worms was as easy as eating or drinking. No, it was as easy as flipping a hand or blinking an eye.
It was simply too easy!
"What kind of trump card does he actually have?" Bai Ning Bing was full of shock and doubt in her heart. At this moment, the image of Fang Yuan in her mind became even more unfathomable.
However, on the surface, she just pouted and said in a flat tone, "You have so many Gu all of a sudden. Can you even keep them alive?"
Fang Yuan smiled. "Of course I can't."
Bone Spear Gu and Spiral Bone Spear Gu fed on milk. That was why they were raised in this milk vat.
Don't be fooled by the vat being full of milk spring water. The consumption was actually massive. It was only like this because the bottom of the vat was connected to a flowing spring.
For Fang Yuan to feed this many Gu, he would need to own a Milk Spring himself.
"Even though I can't feed them, I prefer to take as many as I can. Otherwise, I'd just be letting the Hundred Families have them cheap." Fang Yuan smiled and pointed at the vat again. "Alright, you can destroy the rest of the Gu."
There were truly too many Gu in the vat. Although Fang Yuan had refined a lot, considering the capacity of a Rank 1 aperture, he left quite a few behind.
A moment later, Bai Ning Bing looked at the mangled Gu corpses scattered on the floor with a complicated expression. She was perfectly aware of the immense value of these Gu worms.
Destroying them was like destroying a small mountain of primeval stones. Even Bai Ning Bing felt a pang of heartache.
However, if they were left behind, they would be taken by the Hundred Families. Rather than providing resources to the enemy, it was better to destroy them.
The two left this hall and followed another secret passage into a second bone hall.
