Since Lin Fei transformed into the world itself, his Eternal Realm had seen no changes. This was to be expected. Changes in a world typically occur over tens of thousands, millions, or even billions of years. How much time had passed? Not even a year had gone by, so the lack of changes in the Eternal Realm was perfectly normal.

However, unexpectedly, some changes had begun to manifest in the Eternal Realm, which was unusual. Lin Fei was particularly surprised by this development. Why would there be any changes at this time? Thus, he decided to investigate more thoroughly.

Within the Eternal Realm, Lin Fei had vanquished seven Demon Emperors. The mist of blood from the bodies of these Demon Emperors now permeated the realm. It seemed that the countless Dark Demons he had slain before also contributed to a significant amount of blood mist swirling within the Eternal Realm. This blood mist, filled with the essence of Dark Demon life, slowly began to brew something new.

Stimulated by the essence of these Dark Demons, faint signs of life began to emerge in the Eternal Realm. It seemed as though life was being born.

Lin Fei was taken aback. This new life was created from the essence of Dark Demon flesh and blood and the rules of Lin Fei's Eternal Realm interacting and merging with each other. At last, a new form of life was emerging.

"Wait, could this new life possibly belong to the Dark Demon Domain?"

The birth of this life was indeed related to the essence of Dark Demon flesh and blood. However, after giving it some thought, Lin Fei felt he was being overly concerned. This was his Eternal Realm. Even if life were to be born, it would be the life of the Eternal Realm, not related to the Dark Demon Domain or even the Divine Realm.

Currently, only a hint of life's essence had emerged, not even a rudimentary form of life. Lin Fei sensed something was still missing.

"To give birth to life," he mused, "the environment, the world's laws, and energy are all essential. The essence of Dark Demon life might nourish the life in the Eternal Realm, allowing it to mature fully and come into existence. Once life is born, my Eternal Realm will advance by leaps and bounds, even undergoing a transformation..."

A glint of sharpness flashed in Lin Fei's eyes. He now urgently needed a large amount of Dark Demon life. He even had to actively seek out these Dark Demons, not only to support the Yin-Yang Immortal Domain but also for his own cultivation.

With a swoosh, Lin Fei stepped out and arrived in the Gourd City.

"Are there any battlefields nearby? Preferably with many powerful Dark Demons."

Lin Fei initiated the conversation.

"A battlefield?" The crowd in Gourd City was momentarily startled, then grew visibly impressed. Lin Fei had just slain eight great emperors, saving Gourd City, and now he was ready to head to another battlefield to combat more Dark Demons. His vigor was unmatched, surpassing many True Immortals and Martial Ancestors.

A True Immortal from Gourd City spoke up, "The nearest battlefield is actually quite far. But if Martial Ancestor Lin insists on confronting the Dark Demon Domain, you don't need to go to a battlefield. With your strength, you could become the sharpest weapon on any battlefield. You could roam the vast Yin-Yang Immortal Domain, slaughtering those Dark Demons wherever you find them. This would deal a heavy blow to the Dark Demons."

Moreover, this approach would be less dangerous as it wouldn't involve confronting countless Dark Demons directly. This True Immortal offered Lin Fei a suggestion: to move through the entire Yin-Yang Immortal Domain instead of sticking to the frontlines. Wherever he encountered Dark Demons, he would strike. By continuously eliminating Dark Demon forces, their numbers would eventually reach a limit. Even though the heart of the Dark Demons might continue to spawn new ones, it would take a long time. Each Dark Demon eliminated reduced the threat to the Divine Realm.

"I understand," Lin Fei nodded. After thinking it over, he realized it was indeed a good plan. After all, he only needed the essence of Dark Demon flesh and blood. Where he obtained it didn’t matter.

"Thank you for the advice." After speaking, Lin Fei immediately led the people of the Great Dream Sect and flew out of Gourd City. In the blink of an eye, they had vanished.

Watching Lin Fei's retreating figure, the people of Gourd City looked at each other. The True Immortal from Gourd City sighed, "I didn't expect that Martial Ancestor Lin, who has just achieved the title, would possess such formidable power. Apart from the top demon emperors, few could likely stop him now. With such a powerhouse continuously disrupting and blocking the Dark Demon Domain's armies within the Yin-Yang Immortal Domain, our pressure will be significantly reduced."

Indeed, a mighty Martial Ancestor capable of continuously blocking and slaughtering Dark Demons would not go unnoticed by the Dark Demon Domain. Once they took him seriously and aimed to eliminate Lin Fei, they would have to divert many of their top demon emperors from across the Yin-Yang Immortal Domain. Once these demon emperors were drawn away, the pressure on various parts of the Yin-Yang Immortal Domain would decrease significantly.

With a swoosh, Lin Fei continued sweeping through the Yin-Yang Immortal Domain, clearing it of Dark Demons. Initially, he had been accompanied by members of the Great Dream Sect to repel the invasion of the Dark Demon Domain. But now, it had become a solo performance by him.

Since Lin Fei was dealing with a vast number of Dark Demons, it was incredibly straightforward for him. He simply needed to expand the power of his Eternal Realm. It would spread in all directions, then directly suppress and slaughter. There was no need for the members of the Great Dream Sect; in fact, their involvement would only prolong the process.

Now, Lin Fei needed a large number of Dark Demons to attempt the creation of life within his Eternal Realm. Therefore, he had the members of the Great Dream Sect stay within the Eternal Realm. He was enough on his own!

However, as Lin Fei continued his relentless sweeps, his solo efforts significantly altered the situation across the entire Yin-Yang Immortal Domain. At the headquarters of the Dark Demon Domain, the situation was grim. The collected reports all indicated heavy losses. It seemed a powerful entity from the Divine Realm was continuously sweeping through the Yin-Yang Immortal Domain at an alarming speed. Even the demon emperors struggled to track this entity. If they did find him, typically one or two demon emperors were no match.

Over time, the Dark Demon Domain felt the acute pain of these losses. If this continued, no matter how numerous, the Dark Demons would be exterminated.

"Divine Realm’s Lin Fei?" they questioned. "Who exactly is this person who can sweep so freely through the Yin-Yang Immortal Domain?"

It appeared that only the top demon emperors could possibly stop Lin Fei. But which top demon emperor should they send? Top demon emperors were rare in the Dark Demon Domain, each a dominator in their own right and with a great chance of achieving Supreme status.

Naturally, the most reliable solution would be for a Supreme to intervene. If a Supreme took action, there would be no doubt about the outcome. They could definitely handle Lin Fei. Even if they couldn't kill him, they could at least deter him from rampaging unchecked through the Yin-Yang Immortal Domain.

But currently, there were no Supremes in the Yin-Yang Immortal Domain. Even the Lord of Dark Demons was in the Chaos, leading the Supremes in a battle against the Supremes of the Divine Realm. That was the realm of the Chaos Battlefield, fundamentally different from the battlefield of the Divine Realm.

Therefore, to deal with Lin Fei, they had to rely on the might of demon emperor-level powers!
