On this day, Ye Chen brought Yu Qing, Abenue, the Corpse-Devouring Insect Emperor, Shanji, Will, Qin Wushuang, and others into the deepest part of the Heaven-Fall Mausoleum.
Only a handful of people from the human race could enter this place, and Ye Chen was undoubtedly one of them.
The great tombs here were far taller and more majestic than the others, all capable of reaching into the starry sky beyond the domain, with stars orbiting around them.
Those buried here were basically Ancient Monarchs, their monarchial heavenly might intense. If not for Ye Chen having his Great Emperor reincarnation body here, even someone as powerful as him, a Five Tribulation Chaos Divine King, would find it difficult to withstand such extreme pressure.
After all, there was more than one Ancient Monarch-level powerhouse buried here.
Whoosh—
Ye Chen did not immediately begin cultivation. Instead, he took out the Heaven-Defying Immortal Pond.
The Immortal Pond shimmered brilliantly, emitting billions of strands of Great Dao radiance. Even from the outer reaches of the Heaven-Fall Mausoleum, one could clearly see it and sense the boundless, vast Great Dao laws, far surpassing the profound meanings of the supreme powerhouse Great Dao inheritances comprehended within the various Heavenly Emperor Clans, Immortal Clans, and other human factions, causing astonishment.
This was the most essential part of the Heaven-Fall Mausoleum, the place where the Great Dao essence of countless supreme powerhouses converged, and also the best cultivation ground for advancing realms.
During the twenty-year period of entering the Heaven-Fall Mausoleum, Ye Chen planned to cultivate here. Moreover, during the twenty years in the Chaos Holy Realm, he had already tempered and eliminated the minor flaws left behind from his overly rapid advancement to Chaos Divine King. Therefore, during these twenty years, he did not need to further stabilize his Dao foundation and could focus solely on cultivation.
Naturally, this also benefited from his years of consistently emphasizing the importance of his Dao foundation. Even when his progress was sometimes too fast, he intentionally maintained stability, so no major errors had ever occurred.
"I will begin my cultivation on this day. Inform me before Abenue is about to give birth," Ye Chen said, looking at Abenue with her rounded belly. Usually stunningly beautiful, she was now enveloped in a gentle maternal glow, adding a touch of sacred softness to her peerless beauty.
Having been pregnant for over eighty years, it was likely that in another dozen years, upon reaching a full century, she would give birth. It was just unknown how heaven-defying the fetus nurtured within Abenue's womb would be.
Even now, while soaking in the Immortal Pond, vast amounts of Great Dao essence were continuously and autonomously absorbed by the fetus, as if it had awakened a certain level of spiritual intelligence before birth and could cultivate on its own. Once born, it would likely be another monstrous, world-startling infant.
Ye Chen gave his instructions. Although he very much wanted to stay by Abenue's side, the final trial was in twenty years, concerning the "Supreme One" immortal fate. Even the Sovereign of Formlessness considered it important; otherwise, the various Heavenly Emperor Clans and Immortal Clans would not have descended into the Ten Heavens Ancient Domain just to compete for it.
How could the "Supreme One" immortal fate left behind by the Supreme Ones of All Heavens be anything ordinary?
"My apologies," Ye Chen said apologetically to Abenue.
Abenue gently shook her head: "It's fine. As long as I can cultivate with you, I am content."
Swoosh—
After conversing briefly with his two beloved wives, Ye Chen submerged into the deepest part of the Heaven-Defying Immortal Pond.
The others did not submerge into the deepest part of the pond to cultivate. They cultivated on the surface of the Immortal Pond while also comprehending the Great Dao inheritances from the various monarch tombs in the deepest part of the Heaven-Fall Mausoleum. Even if these inheritances were somewhat incomplete, they could still allow them to comprehend much of the supreme Great Dao, cultivating faster and advancing to another level.
The Immortal Pond seemed small but actually contained another space, about ten li in radius, all filled with Great Dao essence.
The deeper into the pond, the more concentrated the Great Dao essence, even mixed with Great Dao essence from the Ancient Monarch level. Even though the killing intent had been removed, an extremely dense monarchial heavenly might still permeated the area. If not for Ye Chen's Chaos Saint Body, far superior to a Divine King's physique, he would surely explode and perish under such monarchial heavenly might.
Even so, Ye Chen's Chaos Saint Body developed countless extremely fine cracks, as if fine porcelain were crazing.
However, once the Chaos Great Cauldron appeared and enveloped him, he clearly felt the pressure lessen significantly, though the pressure on the Chaos Great Cauldron itself increased, causing cracks to appear on it.
Ye Chen paid no mind to this. With a mouthful, he spat out a Chaos Source Fire, which rapidly expanded. Infinite Chaos Dao Fire filled the entire interior of the Chaos Great Cauldron.
At this moment, he opened the lid of the Chaos Great Cauldron, allowing endless Immortal Pond essence to flood in. It was then refined by being burned within the Chaos Dao Fire mixed with threads of Chaos Source Fire.
Even though this was the Great Dao essence of the supreme powerhouses of All Heavens, it still contained some impurities that needed to be completely expelled and refined to become the purest Great Dao essence, which would also achieve the greatest effect for Ye Chen.
Sizzle, sizzle, sizzle—
Under the continuous burning of the Chaos Dao Fire, large amounts of Immortal Pond essence entered the Chaos Dao Fire. An essence stream as thick as an arm, after being burned and refined by the Chaos Dao Fire, would often shrink by about one-fifth.
One-fifth might not seem like much, but this was the Great Dao essence of the supreme powerhouses of All Heavens, with the deepest parts containing essence from Ancient Monarchs or even Monarchs. Even the impurities held infinite wonders for ordinary Divine Kings, enough to drive countless Divine Kings across the world into a frenzy.
However, Ye Chen strictly refined them out. Even though they still contained extremely powerful energy, they remained dross that could not be absorbed. Otherwise, it would affect the divine power within his body, preventing true solidification and instead making it somewhat unstable, invisibly also weakening his strength to a certain degree.
For this, Ye Chen was willing to accept a slower rate of improvement.
Stream after stream of Great Dao essence, refined through repeated tempering, entered his body. Even Ye Chen's aura began to rise at a startling, albeit slow, pace.
Boom—
Vast amounts of Great Dao essence continuously poured into his body as Ye Chen began a new round of secluded cultivation.
Time flowed leisurely, and five years passed.
The passage of time was so swift it seemed like the blink of an eye.
During this period, the human race in the outside world grew more prosperous and flourishing year by year, far surpassing the past.
Even though the Sovereign of Formlessness was often in seclusion and rarely appeared in the world, he still intimidated All Heavens.
Moreover, there was also a Monarch of No World guarding, along with the human race's nine Ancient Monarchs.
Especially the Sun Monarch, who was also continuously recovering, his cultivation growing stronger year by year. Perhaps in a few more decades, he would completely recover to the peak of his power before his fall in the previous era, becoming a peerless Monarch, even a powerhouse among Monarchs.
During the five years, the effects of the Heaven-Fall Mausoleum gradually manifested. The batch of Heavenly King-level Heaven's Prides who had entered to comprehend the great profound meanings had all made breakthroughs one after another within the short five years. Some Heaven's Prides who had remained at the peak of the Heavenly King realm even successively became Great Powers, once again drawing the attention of the Ten Heavens Ancient Domain.
Without a doubt, the Heaven-Fall Mausoleum was indeed an incubation ground for cultivating super-powerful experts. Especially since it was firmly controlled by the human race, in the long run, the human race would inevitably grow stronger year by year, greatly increasing its power.
