After all, reincarnation is omnipresent, and naturally it is impossible to detect the traces of the soul.

That is why, defeating the Ancient King is easy, but killing an Ancient King is extremely difficult.

Previously, five Ancient Human Kings were possessed by the Dark Clan, but they were still able to reincarnate and be reborn.

This shows the survival ability of the Ancient King, which is simply extraordinary.

"However, the Ancient King is not an immortal existence."

"In this universe, there are still some methods that can kill the Ancient King."

Zhou Sui's eyes revealed a cold light.

If the Ancient King were truly immortal, then the Human clan would not have lost four Ancient Kings. It's just said that an Ancient King is harder to kill than a New King.

Although the means to kill the Ancient King are few, they do exist.

The first method is, of course, absolute power, instantly destroying the Ancient King's soul so that the Ancient King doesn't even have the time to enter reincarnation, thus causing the Ancient King to fall.

In the past, an Ancient Human King ventured into the Eternal Night Land and encountered an unrivaled force.

In just an instant, his soul was annihilated, so he didn't even have the chance to enter reincarnation, and then he died, though mastering power far beyond the Ancient King is exceedingly difficult.

Indeed, such figures exist in the universe, but they have gone through countless cosmic cycles.

That's how they can master this invincible power.

The second method is poison, like the poison of memory. If such a peculiar toxin enters the soul of the Ancient King, it will cling like a festering wound, constantly consuming the soul's memories.

Over time, the Ancient King's soul memories would continuously erode, and eventually, they would completely forget their past.

If all memories of previous lives are forgotten, then there's essentially no difference from death.

In fact, there have been instances in history where Ancient Kings encountered the poison of memory and then entered reincarnation.

As a result, after rebirth, they completely forgot their previous memories and could be considered a second person, forming a new persona.

The third method is a curse, a special type of curse that can attach to the soul of an Ancient King, following the soul through countless reincarnations; unless the curse is destroyed, it will continue to follow.

Feng Jiuyou previously encountered a similar curse, such that even choosing the phoenix's nirvana, she could not escape it, and finally, with Zhou Sui's help, she managed to survive.

If Zhou Sui hadn't helped to remove the curse, Feng Jiuyou would have also been doomed.

The fourth method is possession, a power that only the Dark Clan Immortal Kings can use. They can enter the bodies of the Ancient Kings and devour the Primordial Spirit.

If successful, not only do they devour the Ancient Kings' Primordial Spirit power, but they also gain their memories.

However, if the Ancient Kings wholeheartedly wish to escape, it's not easy for the Dark Clan Immortal Kings to succeed in possessing them.

Of course, all of these methods depend on the Ancient Kings being careless and ambushed by enemies.

If the Ancient Kings are cautious, killing them is almost impossible.

Many times, Ancient Kings die at the hands of those close to them.

"That is to say, I too have methods to take down the Ancient King."

Zhou Sui stroked his chin.

The Dream Soul Gu and Golden Light Thousand Poison Gu on him contain curse power and potent venom.

If used on the Ancient King, they would surely suffer heavy damage.

If they are careless, they might end up dead.

So as long as there is sufficient strength, even beings at the Ancient King level are not invincible.

"The Cave Heaven World has also expanded."

At this moment, Zhou Sui sensed that after advancing to the Ancient King Realm, his own Ancient King Cave Heaven had undergone earth-shattering changes. Originally, in the Immortal King Realm, the scope of the Cave Heaven World was fixed.

After all, the power of law determines the size of the world.

It's like a building; its foundation determines its height.

Some foundations can only support seven or eight floors, while others can support hundreds of floors.

It's the same principle.

Advancing to the Ancient King Realm and integrating with the Reincarnation Law is akin to strengthening the original foundation dozens or even hundreds of times over, allowing this building to reach new heights.

Rumble~~

In an instant, with a thought, Zhou Sui's entire body was like a black hole, devouring the boundless Immortal Qi around him. In just an instant, he turned the surrounding Immortal Qi into a vacuum.

One can imagine how immense his thirst for Immortal Qi has become.

Because even if the foundation is stable and solid, it requires vast amounts of steel and cement to erect floors.

Thus, to expand the Cave Heaven World, large amounts of Immortal Qi and Origin Energy are needed.

Fortunately, his location is precisely at the source of the Human clan's Eighth Grade Immortal Vein, containing endless Immortal Qi.

Over the past three million years, he has used the power of the Gold Eating Bug in the Eternal Night Land to plunder Immortal Veins, increasing the concentration of Immortal Qi in the Human Territory several fold.

Therefore, the Immortal Qi within the Human Territory can fully meet the expansion of his Cave Heaven World.

"Not enough, far from enough."

"More immortal matter, more Origin Energy is needed."

Zhou Sui's eyes revealed a cold light.

He sensed his overwhelming thirst for Origin Energy; even the Eighth Grade Immortal Vein cannot satisfy his appetite.
