A breath of invisible substance lingered on the ferocious ghost claw. It seemed to be between existence and non-existence. Even if the divine sense swept over it, it could not detect its existence.

But when his sight was focused on that strange aura, Shen Yuan clearly felt that an invisible force was eroding Shen Yuan's body through his sight.

Shen Yuan had no idea what impact this almost imperceptible erosion would bring.

"Perhaps it is a special rule, or perhaps it is just a special power born from some unknown world?"

Such a thought suddenly arose in Shen Yuan's mind, and curiosity in his heart drove him to try to control this power.

However, the next moment, the strange scene on the Sun Star flashed through Shen Yuan's mind again, and a chilling feeling instantly swept through his whole body.

"roll!"

The decree to exorcise the gods rang out from Shen Yuan's mouth, and the incense and gods of the Xuanhuang Linglong Pagoda, Fengdu City, and even the entire underworld resonated at this moment.

The mighty force crossed the boundaries of space and suppressed it, and the imperceptible corrosive force completely disappeared in an instant.

The use of the exorcism decree even affected the strange aura lingering on the pagoda spirit's ghost claws.

It may be extraordinary in nature, but under the suppression of the power of incense and gods in the underworld of the entire Xuanhuang Realm, even this strange aura can only die down and no longer show its previous weirdness.

Looking at the cessation of the strange aura, a hint of fear flashed in Shen Yuan's eyes.

"What a strange power, what a secret erosion!"

“It itself is not that powerful, and may not even be able to fight against a wisp of Yuan Qi of the same size, but its own weirdness and corrosive properties make it hard to defend against.

More importantly, its existence seems to be able to secretly drive people's thoughts and make them choose to accept it actively.

If it were to be contaminated by accident, I'm afraid ordinary immortals would not be able to detect the problem."

As he spoke, Shen Yuan looked at Ta Ling with a scrutinizing gaze.

Just a wisp of breath was so strange, and the tower spirit had already been contaminated with strange breath, which made Shen Yuan doubt the tower spirit's current state.

Ta Ling spread his hands and said bluntly:

“Although I have wisdom and can even initially condense my physical form, as long as I have not reached the level of a world-opening treasure, I will never be considered a true intelligent being.

The erosion of this strange aura has a very serious impact on living beings, but due to their small numbers and the fact that I am not a truly intelligent creature, the impact on me is limited.

If I wasn't at the critical moment of manifesting my physical form, this strange aura wouldn't pose any threat to me at all."

As he spoke, the tower spirit even released its ever-changing form, signaling Shen Yuan to check it personally.

Shen Yuan was not polite and used the will of the underworld to continuously explore the condition of the tower spirit's body.

After a moment, Shen Yuan nodded to indicate his approval of the tower spirit's words. This level of strange aura could not affect a half-step world-opening treasure.

Although things did not develop in the worst direction, the emergence of this strange aura still made Shen Yuan alert.

But he did not forget that the fall of Emperor Donghua was closely related to the catastrophe behind this strange aura.

Even the Heavenly Venerable who once possessed the Nine Breaths to Subdue the Qi, the Lord of Mount Tai who died ten thousand years ago, and the missing Emperor Dongyue may all be related to this.

It must be an unimaginable disaster that could cause the death of so many emperors and celestial beings in the Daluo realm.

Originally Shen Yuan believed that the Xuanhuang Realm would be able to protect itself during the catastrophe by cutting off its connection with the upper realm by completely severing the connection between heaven and earth.

But judging from the current situation, this idea is still too optimistic. Even if the connection between heaven and earth is broken, there is still a strange aura infecting the eighteen levels of hell.

"Could it be that there is some kind of loophole in the Jue Tian Di Tong?"

Such a thought flashed through Shen Yuan's mind.

The throne of the Human Emperor, the foundation of the connection between heaven and earth, and the Jiuzhou Ding, which symbolizes the destiny of humanity.

The heaven and earth are blocked by the destiny of humanity, and even the Emperor Tianzun cannot step into the Xuanhuang Realm.

Even the Ten Kings of Hell rely on the connection between the underworld and the netherworld to achieve their invasion goals, and the entire process takes place in the underworld and does not exceed the limits of the present world.

If there really is a loophole in the Jue Tian Di Tong that causes a strange aura to descend upon the Xuan Huang Realm, it must represent a huge crisis.

Seeing Shen Yuan lost in thought, Ta Ling couldn't help but ask curiously:

"Do you know what these strange auras are?"

Shen Yuan turned to look at the tower spirit and shook his head slightly.

“As for the strange aura, I am also unable to determine its nature.

The only thing I can tell you is that these things are not from the Xuanhuang Realm, but are related to a great catastrophe that occurred in the upper realm.

In this catastrophe, even many emperors and celestial masters perished. "

A look of shock finally showed on Ta Ling's ever-changing face.

The strongest being it had ever come into contact with was Ming Hao, who was at the level of a great celestial being. With magical powers inherited from the Three Purities, he was able to suppress the Xuanhuang Qi of the Xuanhuang Linglong Tower with a wave of his hand, which was enough to crush a world.

Even though the Xuanhuang Linglong Tower has now been promoted to a half-step world-opening treasure, it has not yet recovered to its heyday. The tower spirit still does not think that it can compete with the great immortal Minghao at this moment.

If even the great celestial immortals are like this, what about the emperors and celestial masters in the Daluo realm?

However, the catastrophe behind the strange aura can cause the death of the Emperor Tianzun, so one can imagine how dangerous it is.

Realizing this, Tower Spirit's expression became extremely serious as he looked at the strange aura.

Shen Yuan continued to ask the tower spirit:

"Do you know the origin of these strange auras?"

The tower spirit withdrew its gaze with a solemn expression, and with a wave of its hand, the empty scene in front of it changed, and the space began to spread to the entire Xuanhuang Linglong Tower.

The hell worlds spread out in the void like canvases.

The tower spirit pointed at the ghosts who were suffering and wailing in the eighteen levels of hell, and said seriously:

"These strange auras all come from the evil spirits in the eighteen levels of hell."

Shen Yuan looked at the evil spirits who were suffering with sharp eyes. Nothing could escape the will of the underworld. All the evil spirits could feel the invisible pressure looming over their hearts.

With his mind trembling, the pain and torture he was enduring was temporarily forgotten.

There are countless evil spirits in the Eighteen Layers of Hell, but the inspection was still completed quickly under the will of the underworld. However, the result was completely beyond Shen Yuan's expectations.

With his brows furrowed, Shen Yuan looked at Ta Ling with a questioning look in his eyes and said:

"Why didn't I notice the strange aura from these evil spirits?"

Ta Ling's expression remained unchanged. He shook his head slightly and explained:

“Of course you can’t detect the strange auras on these evil spirits, because the strange auras on each evil spirit are so small that they can be almost ignored.

And most of the evil spirits do not have these so-called strange auras.

Just this wisp of energy in my hand has taken me thousands of years to gather.”

The words of the tower spirit made Shen Yuan's pupils tremble slightly, and he couldn't help showing a moved expression. There was only a trace of strange aura in the tower spirit's hand. If this trace needed to accumulate for a thousand years, it was enough to prove that the strange aura on the evil ghost was so little that the will of the underworld could not detect it.

After figuring out the existence of the strange aura, the next question came to Shen Yuan's mind.

"Since these strange auras come from outside the Xuanhuang Realm, how did they enter the Xuanhuang Realm and possess these evil spirits?"

At this point, the clues became even more confusing.

The tower spirit at the side knew the importance of this matter, so he took the initiative to introduce it:

“The evil spirits in the Eighteen Layers of Hell are all dead creatures from the Xuanhuang Realm.

If a living being commits evil deeds during his lifetime and his body is stained with sin, he will be thrown into the corresponding hell.

After they have cleansed themselves of their sins, they will be led by the authority of the six reincarnations in the underworld and enter the real six reincarnations in the underworld to be reincarnated."

"If what you said is that the strange aura comes from outside the Xuanhuang Realm, then it doesn't make sense that the evil spirit is tainted with a strange aura.

Because all the evil spirits are creatures from the Xuanhuang Realm, they have no chance of being contaminated by strange auras. "

Shen Yuan slowly raised his head in deep thought, a bright starlight flashed in his eyes, and he said meaningfully:

"Of course, the evil spirits in the Eighteen Layers of Hell are creatures from the Xuanhuang Realm, but have you ever thought about whether the world in which these creatures from the Xuanhuang Realm lived in their previous life was still the Xuanhuang Realm?"

Ta Ling was startled for a moment, and then his expression changed drastically:

"You mean, they were originally from other worlds, and after death they entered the six realms of reincarnation and were reborn in the Xuanhuang Realm, leaving behind a strange aura?"

Before Shen Yuan could respond, the tower spirit directly denied it:

"Impossible, absolutely impossible!"

“Before a living being enters the six realms of reincarnation, it will first drink Meng Po soup to forget all its memories. Afterwards, it will experience the washing of the reincarnation treasures in the six realms of reincarnation. All its cultivation and magical powers will be annihilated in the reincarnation.

In the end, only a trace of the purest true spirit is left to complete reincarnation.

Nothing can escape the cycle of reincarnation, not even the Golden Immortal or the Heavenly Lord! "

Although the tone was uncertain, Shen Yuan could clearly see that there seemed to be a trace of barely perceptible fear in the tower spirit's eyes.

After all, the answer given by Shen Yuan was too scary. The remnants of the strange aura could actually avoid the erosion of the six realms of reincarnation.

Even after experiencing the six reincarnations, the remaining strange aura is almost undetectable, but it still brings things from the previous life to the next life, which completely subverts the rules of life and death reincarnation.

If this is true, it will definitely cause a huge uproar in all realms.

But compared to Tower Spirit's fear, Shen Yuan seemed much calmer.

He said indifferently: "This is the only possible result, and the only result that meets the conditions.

To some extent, it is precisely because the cleansing of the Six Paths of Reincarnation is indeed effective that the strange aura left in their true spirits is so small that even the will of the underworld cannot perceive it. "

“Under normal circumstances, these strange auras would continue to accumulate in the Xuanhuang Realm. Once the number reached a sufficient level to form a wisp of aura, it would be able to use that strange method to corrode the creatures of the Xuanhuang Realm, thus beginning to spread wildly.

During the period of spiritual energy depletion, no creature in the Xuanhuang Realm could perceive the existence of the strange aura, and no one could resist the erosion of the strange aura.

This is a transition from quality to quantity. If nothing unexpected happens, even if the Xuanhuang Realm cuts off contact with the outside world, it will not be able to escape the impact of the catastrophe."

Having said that, Shen Yuan looked at the tower spirit with his eyes sparkling with starlight, and there was an indescribable weirdness in his expression.

"As a half-step treasure with spiritual intelligence, you have become the biggest unexpected factor in the entire process.

The strange aura gradually accumulates in the Eighteen Layers of Hell, but it cannot erode you, so all the strange auras are retained in the Eighteen Layers of Hell and cannot trigger the influence of the catastrophe. "

Shen Yuan's words stunned the tower spirit. It tried hard to use its brain and use its simple wisdom to understand Shen Yuan's words.

Afterwards, Ta Ling realized the loophole in Shen Yuan's words.

"No! These are just your guesses. They seem reasonable but they hide a huge loophole."

"What loophole?"

“The evil spirits in the Eighteen Layers of Hell are only a small part of the creatures in the Xuanhuang Realm.

If it is true that the outside world's creatures reincarnated into the Xuanhuang Realm and left behind a faint strange aura, and there are so many in the Eighteen Layers of Hell, then there must be even more outside of Hell. The Xuanhuang Realm has long been eroded by the strange aura and it is impossible for it to survive until now."

Shen Yuan smiled slightly and said:

“The strange aura can even corrode immortals. Even if it is weakened countless times and hidden in the true spirit, it will still have a great impact on ordinary people.

Ordinary people who carry a strange aura in this part of true spirits often have strange temperaments and are more likely to go to extremes and commit sins than ordinary people.

The final destination of most of these ordinary people who carry a strange aura is the Eighteen Levels of Hell.

They fell into hell along with the strange aura, and then the strange auras gathered together and corroded you, which led to the current situation. "

Shen Yuan's words left the tower spirit speechless. Its own experience and intuition told it that this was the answer closest to the truth.

After a long silence, Tower Spirit asked Shen Yuan:

"Then what should I do?"

The tower spirit originally didn't care much about this strange aura, but after learning about the catastrophe behind the strange aura and the terrifying power that could break the cycle of life and death, it began to become extremely cautious.

If the strange aura really affects its transformation, it is possible that the strange aura will be integrated into itself and eroded, which is a result it absolutely does not want to see.

Shen Yuan narrowed his eyes and said:

“I can borrow your authority from the incense and fire gods to stabilize your body’s transformation, and even help you suppress the strange aura.

But I need you to sit in the Eighteen Layers of Hell for me and make sure that no weird aura is released."

"I agree!" Ta Ling agreed without hesitation.

This matter involves the eighteen levels of hell. Even without Shen Yuan's promise, it must bear it all.

Seeing this, Shen Yuan nodded with satisfaction.

Then, he raised his right hand, stretched out his index finger and lightly tapped the center of the eyebrows of the tower spirit's transformed body.

The changes in the body stopped instantly, and the tower spirit's body began to be constantly reshaped and frozen by the gathered Xuanhuang Qi. A human-shaped body without any evil ghost characteristics began to appear in front of Shen Yuan.

At the same time, the Yinsi Incense and Fire Road belonging to the Emperor of Fengdu was divided by Shen Yuan, and about one third of the Yinsi Incense and Fire Road began to be injected into the body of the tower spirit, suppressing the evil spirits while intimidating the strange aura gathered on its body.

The scent of incense revived the pagoda spirit, and countless evil spirits in hell seemed to see that at the top of the layers of hell, a great lord of hell was waking up from his long sleep.

The tortured evil spirits tried to pray to the Lord of Hell. Chaotic and impure wishes were born from the layers of hell. The picture of hell outside the Xuanhuang Linglong Tower became more and more vivid.

Shen Yuan looked at the bald tower spirit in front of him, who was wearing golden and red Zen robes and had a strong body, and a playful smile appeared at the corner of his mouth.

“You are the Lord of the Eighteen Layers of Hell, in charge of suppressing sin and burying weird things.

In this way, he should be called Ksitigarbha! "
