If it weren't for Ye Chen's cultivation having reached the Quasi-Monarch level, and him being the most monstrous Chaos Supreme Body, any other Quasi-Monarch, even an Heaven-Defying Quasi-Monarch, would have found it absolutely impossible to detect this extremely subtle difference.
That wisp of unique aura distinctly carried a sense of ancientness and immortality, of supremacy and eternity.
At this moment, Ye Chen opened his eyes and looked towards a certain corner of the void.
"It's right here!"
Beside him, Yu Qing, A Beinu, the Human Race Imperial Sons and Daughters, the Corpse Devouring Insect Emperor, and others all looked towards that corner. However, no matter how they probed, they were unable to sense the slightest difference.
Simultaneously, Ye Chen noticed that almost everyone had stopped, including the Ultimate Ancient Path Overlords and geniuses like the Divine Emperor's Son who were at the Quasi-Monarch level. The powerhouses from both ancient domain worlds all looked towards Heaven's Secret Master as if by prior agreement.
Heaven's Secret Master was currently sitting cross-legged in the void. Above his head, a circular divination talisman disc appeared.
The talisman disc had layer upon layer, densely packed, forming thousands upon thousands of ring-like strata. Each layer was inscribed with numerous talismanic symbols and hexagram signs, all densely packed like the eye of a needle, ancient characters exuding a special aura of heavenly secrets and numerology.
Yet, when one looked deeply, they would be shocked to discover that these overlapping layers of talismanic discs had completely vanished. In their place were the Myriad Worlds of the All Heavens, the Myriad Daos of the All Heavens, the Myriad Things of the All Heavens, the Myriad Spirits of the All Heavens...
This talisman disc seemed capable of deducing everything between heaven and earth. There was nothing that could not be divined, even fate itself could be deduced, all present upon this Heaven's Secret Fate Disc.
This was Heaven's Secret Master's Heaven's Secret Fate Disc, his own Heaven's Secret Fate Disc. It was also the terrifying aspect of the Heaven's Secret Overlord, one of the Nine Overlords of the Ultimate Ancient Path, the most feared among them, who had once in the past compelled several ancient overlords to join forces and pursue him.
Clang! Clang! Clang!—
The Heaven's Secret Fate Disc was constantly rotating. Innumerable secret patterns flew out from it, each a wisp of heavenly secret energy.
The Quasi-Monarchs from both ancient domain worlds watched this scene with shock, for they vaguely glimpsed some astonishing fragments of time from the rotation of this Heaven's Secret Fate Disc, fragments that were actually related to themselves. However, they were very blurry, only catching a fleeting glimpse of their own figures, nothing more.
They all wished to continue watching. No one was uninterested in their own fate. But at this moment, they restrained themselves and remained still, because something more important was at hand: deducing the location of the Fourth Supreme Secret Realm.
Finally, after the Heaven's Secret Fate Disc with its thousands of talismanic rings rotated for a moment, a vast heavenly secret aura began to undulate.
Boom! Rumble!—
Suddenly, the previously cloudless sky became densely covered with layer upon layer of oppressive, city-crushing dark clouds. A terrifying aura of heavenly thunder also began to undulate, causing even Quasi-Monarchs to change expression.
"Forbidden Heavenly Thunder! The Supreme Secret Realm was left behind by a Supreme One. Forcibly deducing it will, to a certain extent, touch upon some taboos. Although it's not the kind of eternal forbidden heavenly punishment tribulation thunder, it still counts as Minor Forbidden Heavenly Thunder, which remains extremely fearsome. Let us join forces to block it. Heaven's Secret Master has now reached the most critical moment."
The several Quasi-Monarchs from the Ultimate Ancient Domain shouted, soaring into the sky.
Huang Di, the Heaven-Defying Battle King, Taiyi, and Wu Dao naturally did the same.
The Quasi-Monarchs from the Supreme Ancient Domain world also acted accordingly.
Boom! Rumble!—
Minor Forbidden Heavenly Thunder, carrying threads of forbidden aura, descended from the sky. It contained an extremely fearsome aura that made Quasi-Monarchs tremble. Now, thousands of bolts rained down.
In an instant, this stretch of heaven and earth became a sea of tribulation thunder, as if the sky were collapsing, utterly terrifying.
Boom! Boom! Boom! Boom! Boom! Boom!—
The Quasi-Monarchs from both ancient domain worlds jointly attacked, blasting towards the Forbidden Heavenly Thunder above. Among them, Yu Qing also made her move, her power terrifying and peerless, sweeping away everything.
Heaven's Secret Master remained seated cross-legged in the void. The countless talismanic rings of his Heaven's Secret Fate Disc rotated like the infinite stars in the sky. Each talismanic character was so minute, yet they seemed to deduce the Myriad Daos of the All Heavens.
Great Dao talismans, numbering in the thousands at the very least, interwove here. Light flickered in this space as strands of aura capable of penetrating the heavenly secrets of the Great Dao began to manifest.
At this very moment, the Heaven's Secret Fate Disc rotated to its utmost limit. Strands of heavenly secret aura appeared, then shot out a single thread of faint light that vanished into the desert land below.
This scene caused the powerhouses from both ancient domain worlds to be taken aback.
The Fourth Supreme Secret Realm was beneath the desert?
It must be known that the powerhouses from both ancient domain worlds, in their search for the Fourth Supreme Secret Realm, had thoroughly combed the entire continent. Not just the area below here, but even the depths of the earth elsewhere had been searched. Where had they found anything?
However, since the Heaven's Secret Fate Disc pointed here, it must be so.
"I'll do it."
Huang Di descended from where he was blocking the Minor Forbidden Heavenly Thunder. With a swing of his heavenly sword, he shattered layers of sand and charged into the depths.
Finally, the heavenly sword emitted a sharp clanging sound, having clearly collided with something extremely hard.
"The Fourth Supreme Secret Realm is here."
Huang Di brandished his heavenly sword. The power of annihilation rippled out, instantly obliterating all obstructing matter and reducing everything within a radius of ten thousand li to utter nothingness.
Yet, the Fourth Supreme Secret Realm was still nowhere to be seen. Only that thread of faint light from the Heaven's Secret Fate Disc pointed before the heavenly sword. There, suspended in mid-air, was a single, minute grain of sand that had not been destroyed.
"One sand, one world; one leaf, one paradise. So the Fourth Supreme Secret Realm was hidden within this single grain of sand. No wonder it couldn't be found no matter what," a Quasi-Monarch sighed softly. After all, they had only probed with their divine sense, not truly attacked. Moreover, the aura of the Supreme Secret Realm was perfectly concealed. Even a Quasi-Monarch's divine sense found it difficult to detect any difference between this grain of sand and the others.
Huang Di swung his heavenly sword, slashing at the grain of sand. Fearsome sword radiance rippled, annihilating heaven and earth. Yet, it was utterly ineffective, for the grain of sand was incomparably hard. Even Huang Di's attack could not break it.
He frowned and said, "The grain of sand has a Supreme seal. I cannot break it."
No one doubted Huang Di's strength. As a Quasi-Monarch, what in the world could he not break? But this grain of sand containing a Supreme Secret Realm was protected by Supreme power. Even someone as strong as a Quasi-Monarch found it difficult to shatter.
At this time, as the Heaven's Secret Fate Disc vanished, the Minor Forbidden Heavenly Thunder also slowly dissipated.
Heaven's Secret Master stood up, possessing a unique divine charm of one who sees through all matters under heaven. He said, "During my deduction, I also calculated that this grain of sand possesses a protective aura of Supreme power. However, it is not very strong. As long as one reaches the level of an Ancient Sovereign, it should be breakable. Therefore, I need everyone to act. Please, do not hold back. This applies to powerhouses from both the Ultimate Ancient Domain and the Supreme Ancient Domain. What do you say?"
"Agreed!"
Faced with such a situation, the powerhouses from both sides did not refuse. Clearly, they all knew that to make the Fourth Supreme Secret Realm appear, they needed to join forces.
