This is...
The aura of spatial fluctuations?
Su Yi was stunned.
Could it be that in this underground world, there is a spatial tunnel or a hidden realm?
Lost in thought, Ning Xie and Mu Xi arrived floatingly.
"Let's go."
Without explaining anything, Su Yi immediately took action and headed towards the direction from which the surging sound like tidal waves came.
Ning Xie and Mu Xi were momentarily startled but followed suit.
With the blood mist pervading and strange rocks towering, this underground world was gloomy and silent, with occasional rushing sounds resembling the surging tide echoing through the air.
On the way, Ning Xie and Mu Xi also realized that Su Yi was heading towards the sound akin to rushing waters!
"This seems to be the fluctuation of spatial power..."
Ning Xie pondered.
"Not seems, but definitely."
Mu Xi corrected without hesitation.
Ning Xie glanced at this young king from the Great Zhou Dynasty, who came from an external family, and said, "It seems that King Zhenyue knows a lot about cultivation-related matters."
Mu Xi smiled faintly and replied, "Aren't you the same with Young Master Su?"
Ning Xie shook her head and said, "How can I compare to Senior Su? In front of him, I truly understand the immense gap between a grain of rice and the bright moon in the sky."
Mu Xi was taken aback, his gaze fixed on Su Yi's back as he fell into silence.
After a long while, he whispered, "I've heard that the competition of the Great Dao is not determined overnight but rather by who can go farther and higher in the end."
Ning Xie's eyes had a hint of strangeness.
How could she not understand the meaning behind Mu Xi's words?
It was equivalent to acknowledging, albeit indirectly, that he was not on par with Su Yi at present!
Ning Xie meaningfully said, "Aspiring to lofty ideals is a good thing. I'm looking forward to King Zhenyue's future performance."
Mu Xi smiled and didn't say much.
"Look over there."
Suddenly, Su Yi stopped ahead and gazed into the distance.
Ning Xie and Mu Xi raised their eyes to look.
They saw a huge blood-colored vortex appearing in the far distance, spanning thousands of zhang in size, slowly rotating and carrying a torrential flow of blood.
At first glance, it resembled a massive gaping mouth between heaven and earth, ready to devour everything!
Ning Xie and Mu Xi's expressions changed drastically. "A spatial barrier?"
Su Yi nodded and said, "Based on the situation, it seems so."
In the cultivation world, wherever a spatial barrier appeared, it meant that on the other side of that barrier, there existed another world or plane!
And now, a spatial barrier spanning thousands of zhang in size, taking the form of a vortex, was suspended deep beneath the Bloodthirsty Demon Mountain.
Could this mean that this place likely leads to another world?
And this is what surprised Ning Xie and Mu Xi!
"Who!?"
Suddenly, a cold voice came from beneath the massive blood-colored vortex.
Su Yi showed no intention of avoiding it and walked straight towards it with his hands behind his back.
Ning Xie and Mu Xi became vigilant. The former had a bright red and translucent fish-shaped flying sword manifesting in her palm, while the latter tightened his grip on his golden war spear.
They stood ready for battle.
As they approached, the field of view suddenly became clear. They saw a vast open space resembling a dojo beneath the suspended thousand-zhang blood-colored vortex.
In the center stood a Daoist altar, above which floated a huge black cocoon enveloped in swirling black mist, resembling a gigantic black silk cocoon.
In front of the altar stood two figures.
One was dressed in a green robe, with sunken cheeks and hollow eye sockets. It was none other than Zhong Yao, the Necromancer.
The other person was a woman wrapped in black mist.
Her figure was graceful and slender, with a bronze ghost mask carved with strange patterns covering her face. In her fair and jade-like right hand, she held a lantern resembling a lotus flower.
In front of her crouched a black giant dog with three heads and six eyes that glowed sinisterly like burning ghostly flames, exuding a fierce and malicious aura.
When Su Yi saw this scene, he couldn't help but be surprised.
"This..."
Ning Xie's pupils contracted, and her gaze fell first on the woman with the lantern and the bronze ghost mask.
This woman... was truly eerie and sinister!
"This scoundrel isn't dead..."
When Mu Xi saw Zhong Yao, he was somewhat astonished.
The mysterious Daoist altar, the mist-shrouded sphere, the indistinct woman, and a three-headed evil dog—all these scenes had an eerie atmosphere.
"The Saintess, it was that kid who killed the Deputy Sect Master!"
When Zhong Yao saw Su Yi, he trembled and spoke with a quivering voice, fear filling his eyebrows.
Saintess?
This title made Ning Xie and Mu Xi furrow their brows. When did the Yin Sha Sect have such a role as a "Saintess"?
"You should leave. This is not the place for you."
The woman with the bronze ghost mask spoke, her voice deep and chilly, like an icy cold wind.
Her deep and indifferent eyes had a hint of strange purple, devoid of any emotional fluctuations as she looked at Su Yi.
Su Yi paid no attention to these words. His gaze was fixed on the huge black sphere floating above the altar as he pondered:
"If I'm not mistaken, this should be a 'Dao Cocoon,' capable of connecting with the other side of the spatial barrier to another world. A cultivator can use it as a bridge to project a divine soul avatar into the 'Dao Cocoon' in order to break free from the cocoon. Am I right?"
"How do you know?" Zhong Yao exclaimed, realizing his mistake as soon as the words left his mouth. His face instantly turned unsightly.
"How do I know?" Su Yi sneered, "If you can't even see through such a small trick, then what am I, Su Yi, cultivating the Great Dao for?"
His words were filled with disdain.
A true Emperor Realm powerhouse can easily tear through the spatial barrier with bare hands, without the need for such elaborate methods.
In other words, those who use the "Dao Cocoon" as a medium for cross-world traversal are destined never to set foot in the Emperor Realm.
Furthermore, when using the "Dao Cocoon" to traverse the world barrier, the original body cannot come over; only a divine soul avatar can be projected into the "Dao Cocoon" for shelter.
To break free from the cocoon, one would need to "possess" a physical body.
If the possessed body is not powerful enough or has inadequate aptitude, even if they succeed in surviving in this realm, their cultivation will be severely weakened, and they may not be able to survive for long...
This is the drawback of using the "Dao Cocoon" to cross the world barrier—it's too troublesome and can lead to various unexpected situations.
"If you have already realized this, then you should understand that staying here will only bring calamity, not fortune," the woman with the bronze mask spoke with indifference. "Once the person inside the cocoon wakes up, it will be too late for you to leave."
Su Yi chuckled. "Then I really want to witness that. You two can stay right where you are."
Ning Xie and Mu Xi exchanged glances and chose to obey.
Meanwhile, Su Yi calmly walked towards the distant dojo, appearing as if he was taking a leisurely stroll.
"You..." Zhong Yao exclaimed in shock and anger, instinctively turning his gaze to the woman beside him. "Saintess, we can't wait any longer."
"I know," the woman with the bronze mask responded.
As she spoke, she suddenly raised the lotus-shaped lantern in her hand.
In that instant, the lantern emitted a black divine radiance, resembling the appearance of a black sun. Its dim light spread in all directions.
Wuwu~~ Wuwu~~
A sound resembling the wailing of ghosts and howling of wolves resounded, and within the area covered by the black radiance, it seemed as if they had entered the realm of ghosts. Countless evil spirits surged out, numbering in the tens of thousands, all charging madly towards Su Yi and the others.
It was like an army of evil spirits, covering the sky and earth!
This scene made Ning Xie and Mu Xi's scalp tingle, their expressions drastically changing.
Perhaps the individual strength of those evil spirits was not formidable, but their sheer number was overwhelming, like an endless ocean.
Anyone who saw this would likely feel despair deep within their hearts!
