With the help of the Thousand Li Earth Wolf Spider, Liu Chen moved as if on flat ground, rapidly traversing layer after layer of the earth, quickly reaching a depth of a thousand li underground.
When he finally landed on the floor of the stone chamber, an ancient and oppressive aura assailed him. Liu Chen unhesitatingly raised the Blade Light Gu in his hand.
Instantly, a bright light cut through the darkness, illuminating the surrounding scene.
The underground space was unimaginably vast. The ground was densely covered with broken swords, like a forest of steel. These broken swords varied in length; some were straight as pines, some curved like snakes, some wide as axes, and some slender as needles. Looking around, their number was simply uncountable.
In the distance, there was also a Sword Tomb, like a small mountain, with a mountain of piled sword blades glinting coldly in the faint light, sending shivers down one's spine.
However, as Liu Chen observed further, he was surprised to find that as he dug the tunnel to enter this place, the air inside began to circulate, and these originally gleaming sharp blades rapidly weathered and decayed at a visible speed.
The sharp sword blades gradually lost their luster, becoming dull, and cracks began to appear on their bodies, eventually turning into a pile of scrap metal.
However, unexpectedly, the decay of these sharp swords did not bring complete destruction; instead, in a sense, it brought new life.
Liu Chen noticed that the soil here seemed to have absorbed the essence of these sharp swords, transforming into a special gu materials—Burial Sword Soil.
This Burial Sword Soil exhibited a peculiar gray color, with a hard yet delicate texture. If a Mortal were to dig it with their bare hands, they would be cut by the soil, as it contained Sword Dao Dao marks.
"So that's how it is, such a miraculous change!" Liu Chen couldn't help but exclaim, deeply captivated by the wondrous sight before him.
Such a transformation of gu materials was rare, and for a Sword Path Gu Master like him, it was an invaluable and hard-to-come-by resource.
According to the memories obtained from Lao Mo, the appearance of this Legacy was due to a violent sea tremor. This sea tremor was so powerful that the entire island was torn in half, and this Legacy was thus exposed.
However, when the Gu Masters discovered this place, it had already been flooded by seawater, and the Legacy was severely damaged, losing the necessary conditions for the formation of Burial Sword Soil.
Unexpectedly, Liu Chen came to this place and accidentally obtained this precious Sword Path gu materials, witnessing this rare phenomenon firsthand.
Liu Chen's heart stirred, and he thought of an excellent idea: if he could artificially create this Burial Sword Soil, then after he ascended to Gu Immortal, this land might be of some help to him.
Thus, he unhesitatingly activated the earth path Gu worm to seal the excavated opening, determined to preserve this Burial Sword Soil and collect it after he ascended to Gu Immortal.
After completing all this, Liu Chen walked towards the Sword Tomb. As he entered the Sword Tomb, he immediately saw a silver-white skeleton. This skeleton had clearly been modified by a sword bone Gu, and even though it was dead, a chillingly sharp Qi faintly emanated from it.
Undoubtedly, this skeleton itself was an extremely precious Sword Path gu materials, which could be used to refine Sword Path Gu worms.
With the System's notification sound, Liu Chen directly opened the amethyst treasure box before him.
"Reward acquired (Sword Forging True Legacy) — The lifelong true Legacy of the ancient Sword Path Gu Master Ou Ye."
The moment the treasure box was opened, a dazzling light suddenly burst forth, like a torrent, directly drilling into Liu Chen's mind.
In this world, Liu Chen saw Ou Ye's entire life. He was like an observer, quietly watching Ou Ye's story unfold before him, like watching a long and wonderful movie.
Ou Ye, this ancient Sword Path Gu Master, primarily Cultivated the Sword Dao and secondarily Cultivated the Refinement Path. However, unlike other Gu Masters, he was not keen on combat; instead, he had an almost obsessive love for refining various Sword Path Gu worms.
In his long life, Ou Ye spent a great deal of time and effort researching and exploring how to refine more powerful Sword Path Gu worms. He constantly tried various methods and Materials, even traveling to deep mountains and old forests to find rare gu materials.
Finally, in his later years, a flash of inspiration led him to conceive of a special Gu worm—the Sword Forging Gu. This Gu worm could use various Sword Path gu materials to assist metal, thereby forging precious swords.
Although Ou Ye's idea was somewhat whimsical, he firmly believed it was feasible. He regarded this idea as his creed, constantly practicing and perfecting it.
In his Legacy, all the broken swords were personally refined by him, and among them were even precious swords comparable to Third Rank Gu worms, but he considered them failures and personally broke them.
He was still very far from his goal. His goal was to forge a Rank Five sharp sword that even a Mortal could use.
Unfortunately, even before his death, he had only managed to forge a precious sword comparable to Four-Turn. Although this precious sword was already very outstanding, Ou Ye still considered it a failed work that did not meet his expectations.
Ultimately, Ou Ye unhesitatingly broke this precious sword with his own hands, because he felt that such a failed work was not worth preserving.
In the end, he could only leave behind his Legacy and die with regret.
"To create a Rank Five precious sword that even a Mortal can use!" This sentence exploded in Liu Chen's mind like a clap of thunder.
After receiving all of Ou Ye's memories, Liu Chen felt a splitting headache, as if his head was about to burst. However, amidst this intense pain, he gained a deeper understanding and appreciation for Ou Ye's idea.
In the Mortal world, Ou Ye's idea was simply Heaven-Defying, completely defying common sense. However, unexpectedly, he almost succeeded!
Liu Chen examined Ou Ye's actions from a unique perspective, discovering some unusual aspects. Compared to the Rank Five Ou Ye, Liu Chen now possessed Lao Mo's memories as a Gu Immortal, which allowed him to see more possibilities behind Ou Ye's approach.
Liu Chen suddenly realized that what Ou Ye was doing was not just simply forging precious swords, but rather building an artificial Heaven and Earth Secret Realm! If Ou Ye had successfully ascended to Gu Immortal and forged enough precious swords, then this plan might truly have been realized.
Unfortunately, things are unpredictable, and Ou Ye ultimately did not achieve his wish.
"No wonder this place could be transformed into the Sword Path gu materials, Burial Sword Soil. It truly is a treasure trove!" Liu Chen exclaimed.
While in this place, a flash of inspiration suddenly struck Liu Chen, and countless ideas gushed forth like a spring. The prototype of an artificial Heaven and Earth Secret Realm Sword Tomb gradually emerged in his mind.
