The unique characteristic of the Sword Embryo Gu is the integration of nurturing and refining; Third Rank is a crucial stage for the Sword Embryo Gu, as once it is refined to Third Rank, its power will surge several times over, making its might not to be underestimated.
Holding this White Bone Sword, Liu Chen couldn't help but feel a surge of excitement.
He thought of an interesting idea: "With this bone sword, I can totally cosplay Li Huowang! Heh, at night..."
He carefully examined the White Bone Sword in his hand, feeling its texture and weight.
When he infused his true Qi into it, a miracle occurred—the joints of the originally tightly connected spine sword, as if by magic, instantly separated, transforming into a long whip.
Liu Chen gripped the hilt tightly, a feeling of effortless ease arising within him.
He wielded the long whip according to his intuition, and the spine sword extended rapidly like a spiritual snake emerging from its Hole, each swing bringing forth a flurry of sword shadows that completely covered a twenty-meter radius around him.
This White Bone Sword not only possessed powerful offensive capabilities, but its defensive abilities were equally outstanding.
Even giant bone spurs as thick as a human's waist were cut into fragments with ease, like tofu, before it.
For the past two months, Liu Chen had been traversing White Bone Mountain, meticulously searching every cave and leaving no stone unturned for any clue.
Although his cultivation had advanced to mid-Third Rank during this period, the search for the Grey Bone Genius's Legacy had slowed down his cultivation speed.
The light in the cave was dim, but his gaze was soon drawn to a massive spiral bone spur, beside which a golden-glowing treasure chest was particularly eye-catching.
Liu Chen's heart quickened; he knew that this treasure chest most likely contained the Grey Bone Genius's Legacy he had been painstakingly searching for.
He unhesitatingly quickened his pace and walked towards the treasure chest.
When he arrived before the spiral bone spur, he took a deep breath, then gripped the bone spur tightly with both hands.
As he rotated it with force, the bone spur emitted a low hum, as if responding to his call.
Suddenly, a slight sound came from the end of the cave, and a hidden secret door slowly opened, revealing a passage to the unknown.
A glint of excitement flashed in Liu Chen's eyes; he knew this was the entrance to the Grey Bone Genius's Legacy.
He stepped through the secret door and entered the Grey Bone Genius's Legacy site.
With Liu Chen's footsteps, he slowly walked into the Legacy cave.
As his figure completely disappeared into the cave's entrance, the secret door, as if alive, slowly closed, eventually returning to its original sealed state, as if this place had never been opened.
Liu Chen walked through the cave; the passage was long and dim.
After a short passage, he finally arrived at a pure white grand hall.
This grand hall was entirely constructed from white bones; the walls, floor, and ceiling were all made of pristine white bones.
In the center of the hall, there was a massive vat filled with milky white spring water, emitting a faint milky fragrance.
Liu Chen curiously walked to the vat and reached his hand into it.
He stirred his hand in the milky spring, and suddenly felt a resistance.
He grabbed hard and pulled out a handful of First Rank and Second Rank Bone Spear Gu and Spiral Bone Spear Gu.
Liu Chen's heart was filled with joy; these Gu were exactly what he needed.
He immediately used the pressure emitted by the Thousand Li Earth Wolf Spider to refine these Gu.
These Gu would later serve as food for the White Bone Sword Gu.
Although Liu Chen had already taken away hundreds of Gu, there were still more Gu rolling in the milky spring inside the vat, and Liu Chen had no intention of taking them all.
Liu Chen, satisfied, left this white bone hall and continued deeper.
Passing through a narrow passage, he arrived at the second Legacy hall.
In the center of this hall stood three massive white bone hands.
The palm of each hand held a Third Rank Gu, which were the Rib Bone Shield Gu, Flying Bone Shield Gu, and Arm Bone Wing Gu, respectively.
A line of text was written above the white bone hands.
"Choose one of three, and be content.
The White Bone Mountain Legacy awaits those who come later."
However, when he carefully observed the three Gu, he found that none of them were particularly outstanding for him.
Liu Chen pondered for a moment and ultimately decided not to take any of them, instead walking directly into the next Legacy grand hall.
This white bone grand hall was clearly the end; an ancient aura permeated its surroundings.
In the center of the grand hall, a human skeleton sat cross-legged, and before its remains lay a bone book, as if silently waiting for a destined person to come and unlock its secrets.
Liu Chen slowly approached the human skeleton and gently opened the bone book.
The book meticulously recorded the life of Grey Bone Genius and the various Gu recipes he possessed.
When he turned to the last page of the bone book, he found a sentence written on it: "If the fated person who comes later is willing, you might as well pay your respects and kowtow three times..."
Upon seeing this, Liu Chen knelt down without hesitation and respectfully kowtowed three times.
He knew very well that the skeleton here was merely a distraction, and the true Legacy was hidden deeper.
After kowtowing, Liu Chen stood up and waited quietly.
After a while, the grand hall, which was originally the end, slowly revealed a side door.
Even with this cave opening, he was not eager to enter, but continued to wait.
He waited patiently for a while longer, until another entrance opened in the grand hall, then he cautiously walked in.
This was a grey bone staircase extending downwards.
This staircase was long, at least a thousand meters.
In the latter half of the journey, the surrounding light gradually dimmed, and the staircase became narrower and narrower.
He reached the end of the staircase almost in complete darkness.
A tightly closed door appeared before him.
Four large characters were carved on the door—Flesh Sac Secret Chamber.
This Legacy site appeared unusually eerie; the surrounding walls were covered with Flesh Sac Gu.
The function of these Flesh Sac Gu was similar to that of the Hidden Flower, both used to store Gu.
However, unlike the Hidden Flower, the Flesh Sac Gu had the appearance of a giant mouth, not only possessing lips, teeth, and a tongue, but also being lifelike, making people feel a sense of fear and eeriness upon seeing them.
Liu Chen knew the plot here like the back of his hand; he didn't even bother to take the miniature bone book, but instead walked directly to the Flesh Sac Gu, unhesitatingly pressed his hand against its teeth, and casually tapped them.
Surprisingly, the Flesh Sac Gu slowly opened its mouth under his manipulation, directly revealing a hidden entrance.
"What exactly does this mean? Are they not giving me even one Gu?" Seeing this, Liu Chen couldn't help but feel a bit annoyed.
He continued to press the teeth of the Flesh Sac Gu forcefully, hoping that some Gu would be spat out, but no matter how hard he tried, no Gu appeared.
Perhaps because Liu Chen had been operating for too long, the Flesh Sac Gu finally reacted and spat out a Third Rank Sword Bone Gu.
Seeing this, Liu Chen quickly put away the Gu before reluctantly stepping into the passage.
