Within the furnace, He Xian waited quietly. After this tempering, he would weather his heavenly tribulation and advance into Escape One.
Boom!
The next moment, the Yin-Yang Furnace, divided into the two inner furnaces of yin and yang, began to reveal its effects.
Within the Yang Furnace, the ancient, unadorned walls began breaking down the precious medicines and corpses. The searing temperature abruptly rose as Dao Fire enveloped them.
At the same time, the Yin-Yang Furnace began to spin.
Clang!
Suddenly, the Yin-Yang Furnace seemed to have been struck, releasing a mighty sound. At that moment, it seemed less like a furnace than a great ceremonial bell, its peal stirring even the deaf and rousing all who heard it.
Then, the resonance of the Dao spread with that mighty sound, drawing those inside the Yin Furnace into a wondrous state of enlightenment.
Boom!
The aura of the Great Dao permeated the air. The Emperor Clan corpses inside the Yang Furnace began to melt, revealing complete Dao traces that now emerged in full.
The Yin-Yang Furnace could break down all things into the two energies of yin and yang and elucidate the principles of the laws. This was why even Undying Kings would covet it: it could lay the firmest possible foundation in the Dao for their descendants.
A mass of energy enveloped He Xian, abruptly shrouding him in haze. It was a mysterious transformation.
"This is that child Gu Hong's great opportunity!" the Gu Clan's old Supreme said. Gu Hong was his own grandson, and the old man grinned from ear to ear.
"He now has a foundation for becoming Undying." Even for members of the Emperor Clans, breaking through to become Undying was extremely difficult. That was why the old man was smiling.
The Foreign Realm's Undying were both numerous and few, depending on how one looked at it. Their numbers had accumulated over time.
Inside the Yin Furnace, He Xian opened his eyes, waiting for nourishment to flow back from the Yang Furnace.
The supreme treasure that was the Yin-Yang Furnace was analyzing the corpses, beginning to reveal the complete Great Dao of each Emperor Clan member. He was especially interested in the Wu Shang Lineage's Ten Thousand Laws Cannot Invade.
Then again, there was probably no one in the world who was not interested in that lineage's secret art.
"Focus your mind and experience it carefully! It is as though the Heavenly Dao itself is expounding the scriptures. Comprehend it earnestly, and you will reap great rewards!" the Gu Clan Supreme shouted.
Inside the furnace, the various corpses were being broken down, while minerals such as king blood stone were also being refined. Abundant medicinal potency spread out, beginning to nourish He Xian and Gu Hong.
Boom!
The two energies of yin and yang revolved, and both inner furnaces trembled together, forming an inexplicable connection. The Great Dao revealed itself. He Xian closed his eyes and listened intently to its true words.
Without a doubt, the Yin-Yang Furnace defied heaven. As it resonated, it used the two energies of yin and yang as a bridge to see through all things, beginning to elucidate the paths of the Emperor Clan members.
This was also what the Gu Clan's old Supreme had hoped for. He had swallowed his pride and taken a risk to send his own descendant inside. This truly was a heaven-defying blessing.
It would allow Gu Hong to use the myriad Daos as kindling-not to imitate them, but to learn from them and perfect himself, thereby setting foot on a glorious path.
His grandson was one of the Gu Clan's two most outstanding beings of this era.
Rumble!
The Yin-Yang Furnace rocked continuously, rising and sinking within Stone Valley as it drew in the rules of heaven and earth. Order Divine Chains from all the heavens encircled it.
At that moment, it looked profoundly sacred.
Clang!
The furnace shuddered again, its lingering note like the peal of a great bell. The sounds of the Dao thundered, carrying so far that they could be heard even outside the Gu Clan Ancestral Land.
Many beings heard that bell and immediately sat cross-legged to comprehend the Dao.
"That is the ringing of the Yin-Yang Furnace, the Gu Clan's supreme treasure," some quickly guessed.
"He Sky-Supporting entered the Gu Clan to temper his body once again!" others exclaimed in surprise.
He Xian had not concealed himself when he arrived at the Gu Clan.
"Wasn't his body already a match for a half-step Supreme? Is he going to attain the full Supreme level now?!"
Someone gasped.
All the beings of the Foreign Realm remembered the terrifying sight of He Xian's body breaking through to the half-step Supreme level in his last battle. It had made the world reevaluate the Crane Clan's Indestructible Scripture.
It had all but been hailed as the greatest body-cultivation scripture of the age.
The scene returned to Stone Valley within the Gu Clan.
The extraordinary manifestations here were even more astonishing.
This ancient furnace was truly too mysterious. It possessed unfathomable power that could change everything and allow someone to defy heaven and rewrite their fate, provided the price paid was great enough.
The two energies of yin and yang circulated around the Yin-Yang Furnace as it bobbed continuously in midair. The aura of the Great Dao grew ever denser. Even some Gu Clan Supremes who had not shown themselves were already deeply moved.
More and more beings sat cross-legged outside the Gu Clan Ancestral Land, comprehending the Dao!
Whoosh!
Streak after streak of purple energy swept through heaven and earth. It was the Great Dao descending, manifesting tangible forms: blooming lotuses, faint voices chanting scriptures.
There was also a ferocious beast, crimson from head to toe-a Time Beast.
Rumble!
Inside and outside the Gu Clan Ancestral Land!
The aura grew ever more majestic, captivating everyone's mind.
Yet quite a few people coughed up blood, their bodies swaying as the sounds of the Dao injured them.
A wave of unrest swept through the Gu Clan Ancestral Land.
Even Supremes secretly trying to comprehend the Dao felt a sharp pain between their brows. They quickly stopped and fell silent again, not daring to delve any deeper.
"Children of my Gu Clan, do not try to resonate with the Yin-Yang Furnace! It is analyzing the Great Dao, and this process is extremely dangerous. Though it has drawn in the rules of all the heavens, they are not suitable for contemplation!" a Gu Clan Supreme warned loudly.
Only these old fellows knew that although the Yin-Yang Furnace seemed calm, its Dao sounds sacred and ancient, it was actually dangerous. Those sounds could not be contemplated.
Chirp, chirp!
At that moment, laws entwined the Yin-Yang Furnace, making it increasingly indistinct. Yet every tremor made people's hearts and souls shudder. That aura seemed almost capable of destroying heaven and earth.
It was as though it were opening the heavens, reenacting the creation of the world and evolving the Great Dao.
Within Stone Valley, thunder seemed to explode. Chaos energy surged in rolling torrents, and vast swathes of laws interwove and collided, producing terrifying spectacles.
Hiss!
The sun and moon shook, and heaven and earth cracked.
Soon, a curtain of light rose within the valley, seemingly about to tear the firmament apart. A casual tremor of the Yin-Yang Furnace was enough to produce utterly terrifying manifestations.
Only the most ancient beings knew that although the Yin-Yang Furnace contained great blessings and could draw down the rules of all the heavens, those outside had no opportunity to partake.
Only those within it, inside the Yin Furnace, could do so.
By now, even some Undying would have been green with envy.
Indeed, the inside of the furnace was far more peaceful than the outside, for the circulating energies of yin and yang neutralized everything. It was precisely the presence of these two energies that made it possible to perceive the Great Dao of heaven and earth.
The Dao gave birth to one, and one gave birth to two. These so-called two could be interpreted as yin and yang. By using them as a guide, one could touch the complete Great Dao between heaven and earth and evolve all things.
This was what made the Yin-Yang Furnace so heaven-defying!
Of course, after being nurtured by generations of Gu Clan experts, the furnace had grown increasingly gentle, making it suitable for enlightenment and cultivation.
He Xian formed seals with both hands, steadying his body.
The next moment, the Yin Furnace and Yang Furnace began to rotate, joining together.
Boom!
At the same time, the furnace grew ever more radiant, drawing those complete Dao laws down from the outside world.
Now, the mighty chanting became clear. The paths of the Emperor Clan members began to unfold, and He Xian focused his attention on the indistinct figure holding the Bronze Halberd.
The principles of Ten Thousand Laws Cannot Invade began to unfold, step by step!
