The fact that the 'Ultimate Supreme' Immortal Fate was actually Pangu's Heart was a secret not even the various Heavens' Supreme Ones had discerned.
However, it was likely that some of the most terrifying Giants within the Chaos Sea knew, such as Tai Sheng Huang and the Battle Saint Ancestor, who had both spoken, urging Ye Chen to obtain this 'Ultimate Supreme' Immortal Fate at all costs.
Now, thinking back, Pangu's Heart had been sealed by someone, becoming the later 'Ultimate Supreme' Immortal Fate, deceiving the heavens and crossing the sea, with none being the wiser.
The most powerful batch of Giants probably knew, but there should have been an agreement among them, which was why they didn't personally fight over it. Instead, they let their own descendants or the most outstanding talents from their respective Chaos Ancient Universes and factions compete for it, thus transferring it layer by layer into their own hands.
Unfortunately, no one could have anticipated that in the end, the 'Ultimate Supreme' Immortal Fate was seized by Ye Chen, who had appeared out of nowhere.
At that time, many of the strongest Giants wanted to take action and snatch it from him. However, hindered by the original agreement, and also because the most powerful batch of Pangu Giants like Tai Sheng Huang, the Battle Saint Ancestor, the Defying War Lord, the Time-Space Great Emperor, and others were absent, and the Human Emperor had been in deep slumber for many years, they refrained from acting to avoid letting more Giants learn of this great secret, which would lead to more powerful Giants joining the fray.
Moreover, although Ye Chen possessed world-shaking cultivation back then, he had always kept it hidden deep within his body. For a long time, he focused on arduous cultivation solely to face the immense threat from the alien ancient universes. He never truly unveiled the true face of the 'Ultimate Supreme.' It was only after arriving at the Eternal Heaven Realm that he coincidentally managed to unveil it.
"Pangu's Heart is right here. It is because of Pangu's Heart that I was able to touch the secrets of the Eternal Ancient Stele," Ye Chen sighed, having discerned many things.
At the same time, his gaze towards Pangu's Heart burned with intense fervor.
Without a doubt, if he refined this Pangu's Heart into his body, he could likely directly ascend to the level of an Overlord of the Chaos Sea, just like the progenitor of the Origin Saint Race in the past, sweeping through all opposition until the Heavenly Emperor, the Primordial Ancestor, the Immortal Ancestor, and others appeared out of nowhere, truly breaking the Origin Saint Race's domination over the Chaos Sea.
With Pangu's Heart, he was fully qualified to contend for the position of Overlord in a short time, becoming one of the supreme rulers of the Chaos Sea.
But in the end, Ye Chen gave up. He did not refine Pangu's Heart into his body.
Although refining Pangu's Heart would allow him to become a Half-Step Eternal—an invincible Overlord—in the shortest time, ultimately, Pangu's Heart was an external force, not something belonging to himself. Moreover, doing so would likely completely limit his further progress. In this lifetime, he might never have the hope of breaking through the shackles to become truly Eternal.
He still had the Chaos Great Dao. If he could achieve Great Perfection relying on the Chaos Great Dao, he would transform into a true Eternal, not merely become an Overlord by borrowing Pangu's Heart.
"Although I cannot refine it, Pangu's Heart is an Eternal Heart. Cultivating by borrowing the Eternal Heart allows me to devour more Eternal Power. It's equivalent to constantly devouring Eternal Power, as if my Chaos Great Dao is advancing step by step towards Great Perfection at all times. Sooner or later, I will also reach the level of an invincible Overlord."
Ye Chen thought to himself, already formulating a corresponding plan at this moment.
He placed Pangu's Heart within his Chaos Small Universe, where it continuously provided vast amounts of Chaos Divine Power for Pangu's Heart to devour. In turn, Pangu's Heart exhaled purer and more powerful Eternal Power for Ye Chen to absorb. This also meant that the unusable Chaos Divine Power within his body was tempered, becoming even stronger!
Ye Chen was in no hurry to leave immediately. His gaze was profound as he sat cross-legged within the space of the Eternal Ancient Stele, continuing to discern more secrets.
He didn't know how much time had passed before his consciousness withdrew from the Eternal Ancient Stele. The phenomena here had long since dissipated.
He saw Donghuang and the other Great Heavenly Venerates watching him closely. Donghuang said directly, "Fellow Daoist Ye, how do you feel? In all these years, you are the first to trigger phenomena from the Eternal Ancient Stele."
Ye Chen understood this was because of Pangu's Heart, but he naturally wouldn't elaborate. He simply replied, "Very well. I gained profound insights."
Knowing Ye Chen likely had other secrets, but they belonged to him, the other Great Heavenly Venerates naturally couldn't press him to reveal them. They just nodded.
Donghuang said, "Fellow Daoist Ye, do you wish to rest for a while, or proceed directly to the Critical Location?"
"Let's go directly."
This trip to the Eternal Ancient Stele had yielded great gains. He learned that the true secret of the 'Ultimate Supreme' Immortal Fate was Pangu's Heart and truly understood the origins of the five invincible Overlords of the Chaos Sea. However, he was still quite curious about the Eternal Heaven Realm and wanted to know what great secret was hidden in the Critical Location of this ancient secret realm that had drifted out from the Origin Land.
"Agreed!"
Leaving only one Great Heavenly Venerate behind, the other Great Heavenly Venerates accompanied Ye Chen to the Critical Location of the Main Celestial Domain.
The Heavenly Venerates ascended directly into the heavens, crossing the Thirty-Three Heavens along the way.
These were the true Thirty-Three Heavens of the Eternal Heaven Realm, while the Thirty-Three Celestial Domains were merely their projections.
Each of these Thirty-Three Heavens was vast and boundless, surpassing the celestial domains below. Moreover, each had a Heavenly Venerate Dharma Body constantly guarding it to prevent anyone from accidentally trespassing.
Thirty-Three Heavens, guarded by thirty-three Heavenly Venerates. One could imagine that this Critical Location was absolutely unknown to most, concealing a world-shaking secret.
Of course, given Ye Chen's current status, he would soon learn of it.
The Heavenly Venerates crossed the Thirty-Three Heavens, arriving at the highest, the Thirty-Third Heaven. It was a vast, boundless place, not exactly void, but where the myriad Daos did not exist. Only the most intense Eternal Power surged here.
"Such dense and powerful Eternal Power," Ye Chen exclaimed in surprise. He also felt the Eternal Heart at his brow's Muddy Pellet Palace pulsating. With each pulsation, it frantically devoured the Eternal Power here, which had turned into a mist-like form, as if wanting to completely swallow all the Eternal Power to recast that indestructible Eternal Heart.
At the very center of this vast, boundless place sat an immensely powerful and majestic figure. Even someone as strong as Ye Chen felt a sense of pressure. Clearly, this was the other Half-Step Overlord guarding the Thirty-Three Heavens.
Whoosh—
This Half-Step Overlord opened his eyes. It was like the flash of lightning that cleaved heaven and earth, landing on Ye Chen.
Ye Chen met his gaze without retreating an inch.
"Hahaha, Fellow Daoist, you must be the Chaos Half-Step Overlord from the Primordial Immortal Realm," the Half-Step Overlord laughed heartily, appearing exceptionally forthright and cheerful. He stood up, looking quite burly. He had special patterns on his body, was in human form, standing fifteen feet tall like a wild man, with messy hair, but no one could ignore his presence.
