When a powerful law is integrated into a formation, it can become a fifth-tier grand formation.

The stronger the law, the more powerful the formation!

The reason Xu Hei couldn't leave was precisely because the formation here contained not only the law of life and death but also a hint of the mysteries of reincarnation.

The involvement of reincarnation laws made the formation so formidable.

Once the laws are introduced into the formation, everything becomes clear.

"The so-called handiwork of deities is nothing more than a formation too strong for the Sea Star Demon Clan to comprehend, thus mistaken for divine work!" Xu Hei said.

"Yes, yes, that's right!" Yu Shiyu nodded in agreement.

Such words were considered blasphemous to the deities, something the people of Sea Star wouldn't dare to say, but Xu Hei dared to express it.

This rationality was something she admired greatly.

Xu Hei's figure flickered as he moved toward the underwater pyramid.

Before long, he arrived in front of the Ouroboros statue again.

Yu Shiyu followed from a distance, not daring to get too close or too far.

Xu Hei stared at the pyramid, his divine sense spreading out, slowly penetrating from the outside in. If there was a core to the formation, it seemed to be inside this pyramid.

Perhaps because he had absorbed it for so long, Xu Hei no longer encountered attacks from the law of life and death.

Xu Hei's divine sense entered the pyramid, descending toward the dark and deep area.

Suddenly, Xu Hei felt a strong pulling force acting on his divine sense, as if dragging it downward.

If it were the divine sense of someone at the Elemental Infant stage, it would have been torn apart instantly, dying beyond death.

However, Xu Hei stabilized his primordial spirit, releasing the laws of heaven, and the devouring force suddenly spread out, countering the pulling force.

Gradually, the two forces reached a balance.

Xu Hei took a deep breath, and his divine sense continued to delve deeper.

After passing through the pulling force, Xu Hei encountered no further threats. A stick of incense later, his divine sense arrived in a dark underground space.

Here, numerous stone pillars stood like pillars of heaven, towering in all directions. The light was dim, resembling an underground prison. Each stone pillar emitted a strong soul power fluctuation, like the breath of souls.

On some of the stone pillars, human-shaped outlines could still be seen.

"What are these..." Xu Hei's pupils shrank after sensing carefully.

"Are these the souls of cultivators after death?"

Xu Hei stared at the stone pillars, his heart surging with waves.

If his guess was correct, the soul fluctuations on these stone pillars were left by the souls of the deceased, and the number was astonishingly large!

Suddenly, Xu Hei felt a sense of crisis and quickly withdrew his divine sense, returning his consciousness.

Xu Hei gasped for breath and, after a moment, stared at Yu Shiyu and asked, "In the legends of Sea Star, is Death God the deity who governs life and death reincarnation?"

"That's right!" Yu Shiyu nodded. "It's said that after people die, their souls come to the Sea of the Reaper to enter a new cycle of reincarnation. Sometimes, to allow the clansmen to be reborn quickly, they even hold sacrificial ceremonies, throwing corpses into the Sea of the Reaper."

After hearing Yu Shiyu's explanation, Xu Hei had a bold guess in his heart.

This place might have been left by an ancient mighty figure, specifically to absorb souls for some kind of ritual.

If, as Yu Shiyu said, all souls of the deceased come here, how terrifying would the number be?

What realm of cultivator could have orchestrated this?

The so-called early reincarnation and rebirth were just a facade.

Having just seen those, could Xu Hei have unknowingly offended the so-called Death God? No need to think; he already had, having absorbed the law of life and death.

Death God had existed since an unknown era, and even if still alive, might have ascended to the Spirit Realm.

In this way, could the seven deities of Sea Star also be, like Death God, using the Sea Star cultivators in some way?

"What did you see?"

Yu Shiyu noticed Xu Hei's odd expression and couldn't help but ask.

"Nothing."

Xu Hei didn't disclose what he saw, to prevent this foolish woman from speaking recklessly.

However, he had also found the core of the formation. The source of all energy here was nothing but those deceased souls.

Energy doesn't appear out of thin air, and so many laws of life and death wouldn't emerge without a source.

The source was those deceased souls.

The terrifying will within the heavy oil was also transformed from the remnants of the souls after death.

"As long as those stone pillars are destroyed, everything here will be resolved." Xu Hei thought, taking out a purple-gold cannon.

The puppet cannon was common in the Divine Puppet Sect, with everyone from ancestors to disciples having one.

But the one in Xu Hei's hand was different; this cannon could withstand extremely strong spiritual power infusion without damage, with a low minimum and a very high maximum.

This was the best one Xu Hei had specifically requested from Daoist Sparrow after seeing him use it.

Xu Hei immediately performed the Diamond Suppression Technique, compressing his true essence. After compression, the power of the true essence skyrocketed, compressing from purple to black, getting smaller and smaller until space distorted, then infused into the cannon.

In battle, Xu Hei wouldn't do such a thing, as it would make him a sitting duck. Only now did Xu Hei dare to do so.

Yu Shiyu watched with her heart pounding.

"You don't just stand there, channel your spiritual power over here," Xu Hei shouted.

"Okay."

Yu Shiyu came over, raised her hand, and pushed, sending a vast amount of spiritual power from her palm toward Xu Hei. Xu Hei accepted it all, absorbing it into the Demon God Cauldron, then compressing it through the cauldron and infusing it into the cannon.

Xu Hei did this to test her.

If Yu Shiyu harbored ill intentions, she could easily strike, and Xu Hei would suffer a heavy blow. Although she had revealed much valuable information, Xu Hei wasn't at the point of complete trust.

During this time, Xu Hei deliberately exposed a flaw, but Yu Shiyu had no other thoughts, only inputting spiritual qi.

In an instant, an hour passed.

Yu Shiyu was already exhausted, sweating all over, and even her clothes were barely holding up, about to dissipate.

After infinite compression, the cannon in Xu Hei's hand also emitted cracking sounds, and the surrounding space twisted.

Compressing for an hour, Xu Hei had never been so reckless.

This was definitely the strongest strike Xu Hei had unleashed since his Divine Transformation.

"The cannon is at its limit, just this one strike!"

Xu Hei grabbed the cannon, moved beside the pyramid, performed Earth Concealment Escape, and headed underground toward the stone pillars.

"You go first, get as far away as possible," Xu Hei's voice came.

Yu Shiyu nodded quickly and floated away.

Moments later, Xu Hei arrived above the pitch-black hall, stopping at a perfect position.

"This is it!" Xu Hei aimed below.

He first performed space confinement, then instantly teleported several times to ensure a quick escape.
