431: Nine-Nine Yuansha Soul-Killing Formation

Earth Immortal Realm!

A massive, cyan-gold orb of light was surrounded by countless pitch-black stone pillars.

The stone pillars were arranged in a certain formation, each in its corresponding position.

There were ninety-nine such stone pillars in total, primarily crafted from a material called Earth Nether Corroding Soul Stone, combined with other materials.

From a distance, black smoke billowed out, and an boundless aura of malevolence assailed one's senses.

Even a powerful Venerable-level expert would be affected if they drew near.

This was even with the stone pillars in an inactive state.

Together, they formed a grand formation—the Ninety-Nine Primordial Malevolence Spirit-Slaying Grand Formation!

When fully operational, it would require an additional infusion of resentment-malevolence soul crystals collected by the user to activate it to its maximum potential.

The Ancient Hall's decision to slaughter the living beings of the Four Profound Heavens back then was precisely to collect these items.

Among all worlds, including the Four Profound Heavens, only the Four Profound Heavens could provide such a vast quantity of resentment-malevolence soul crystals.

As for those from the minor worlds, their origins were weak, and thus their living beings were naturally weak; the amount of resentment-malevolence soul crystals they could produce from the same number of lives would be less than that of the Four Profound Heavens.

Typically, the output of a single minor world would probably not even be enough to form a single resentment-malevolence soul crystal.

According to the Ancient Hall's meticulous calculations, the combined output of all currently known minor worlds was less than a fraction of the Four Profound Heavens'.

If these were given to that Heaven Forsaken Demonic Spider, it would be more than enough for it to become a Great Accomplishment Sacred Lord.

Otherwise, Wang Teng would not have wanted to harm the Four Profound Heavens, as it was the world where he was born and raised.

Wang Teng stood before the grand formation, watching his subordinates set it up.

In truth, everything that needed to be set up was already in place; it was just that, given its immense importance, it was necessary to double-check everything.

Otherwise, if anything went wrong with the grand formation, not only would all their efforts be in vain, but they would also lose any chance of achieving immortality in the future.

Therefore, Wang Teng had to be extremely cautious.

At this moment, a figure flew out from the formation, clad in dark, luxurious robes, and stopped beside Wang Teng.

The person was none other than Holy Monarch You Tian. He looked at Wang Teng with fervent eyes. "Reporting, Lord Hall Master, the ninety-fifth inspection has been completed, and there is not a single issue with the grand formation.

Furthermore, all the resentment-malevolence soul crystals are ready, and top-grade spirit sources and world sources are also prepared.

As soon as you give the order, we can begin at any time."

Wang Teng nodded. With his obsession about to be fulfilled, his heart was no longer as eager as before.

Next, he would embark on his journey to the upper planes.

He gazed at the cyan-gold orb of light in the center of the grand formation—that was the Four Profound Heavens' last chance for immortality—the Innate!

That's right, that cyan-gold orb of light was an Innate Divine Saint still in gestation!

Innate beings are born immortal.

From the moment he completes his gestation, he will be at the immortal level, at least an Immortal Law Realm existence.

During an exploration millions of years ago, this Innate existence, still in gestation, was discovered.

The so-called Innate, born of heaven and earth, can be considered a native existence whether in the upper or lower planes.

Therefore, theoretically, both upper and lower planes can give birth to Innate Divine Saints.

However, in reality, the lower planes do not possess the soil sufficient to bear the birth of an Innate.

The energy alone required for his gestation is extremely terrifying, and no minor world can bear the burden.

So, while Innate beings are said to be able to achieve immortality in both upper and lower planes without any regional targeting, it is impossible for an Innate to be born in the lower planes.

According to various investigations, this Innate being, while still in gestation, fell along with the Four Profound Heavens, a fragment of an upper plane.

However, although the Four Profound Heavens is a fragment of an upper plane, it has already fallen.

How could the environment it provides for the Innate compare to when it was in the upper plane?

To gestate an Innate, it must be in an extreme environment—under extremely excellent environmental conditions.

And such an environment is incredibly rare, even in the upper planes, let alone in the lower planes.

Therefore, throughout these countless years, this Innate existence has only been able to maintain its already gestated self, slowly absorbing power to perfect itself.

If nothing unexpected happens, it will remain in this state for a very, very long time.

This is even in the Four Profound Heavens—the most powerful minor world among the lower planes.

If it had fallen elsewhere, it would only slowly return to the void and then forever sink into oblivion.

But now that it has been discovered, its fate will naturally be completely different.

That's right, what Wang Teng and his group are doing now is helping the Innate complete its gestation.

The environment for gestating an Innate is very difficult to form naturally; it is exceedingly rare even in the upper planes.

So Wang Teng chose to artificially create such an environment to aid its gestation.

But this does not mean he has the ability to create an Innate; Innate beings are born of heaven and earth; he is merely incubating an embryo, a semi-finished product.

Gestation requires lower environmental conditions than formation, so Wang Teng's efforts in the Four Profound Heavens can achieve it.

If it were formation, even those in the upper planes might not be able to manage it.

From the moment Wang Teng discovered the cyan-gold orb of light, he began endless research on it.

Such a legendary existence from the upper planes, he absolutely had to utilize it, and utilize it well.

After countless years of effort and research, he finally found a feasible plan.

Devour the opponent's Innate Origin, transform into an Innate existence, and ascend to immortality!

But how to do it still needed careful planning.

Because Wang Teng needed a complete Innate Origin; otherwise, his transformation would be incomplete, and he would still retain a trace of the upper planes.

It is very likely that the endless reincarnation would not acknowledge him and eliminate him.

After all, an incomplete transformation is equivalent to no transformation at all.

But once it is fully gestated, it will become an immortal upon birth.

Leaving aside whether he could handle it after it became an immortal.

If it became an immortal and was instantly taken away by the endless reincarnation, Wang Teng might not even have a chance to act.

Therefore, this matter required a long-term strategy.

To this end, Wang Teng led the Ancient Hall in researching and preparing for a very long period.

But before that, he first sealed the Innate orb, preventing it from absorbing any nutrients to gestate itself.

From Wang Teng's perspective at the time, given how far along this Innate had already gestated, he couldn't take any risks.

If it suddenly completed gestation while he was researching a method, that would be laughable.

After expending a great deal of effort to seal it, he continued his research, and the results were remarkable.

The Ninety-Nine Primordial Malevolence Spirit-Slaying Grand Formation!

This was the final outcome of the Ancient Hall's research, their solution to the anticipated situation.

They conducted multiple debuggings and simulations, only daring to implement it after gaining complete confidence.

After all, if this attempt failed, there would truly, truly be no other opportunity; no amount of caution was too much.

Scenes from the past flooded his mind; for the sake of ultimate immortality, Wang Teng had fought and sacrificed too much.

He went to the position of presiding over the grand formation, personally controlling it; no one understood this grand formation better than him.
