After joining the Supernatural United Bureau.
Xu Xi had already known.
The arrival on Earth was not just various supernatural beings, but also fragments from the supernatural world, carrying landscapes, buildings, and more from other realms.
These fragments from other realms were officially named【Boundary Ruins】.
The hidden value of Boundary Ruins was extremely high. By studying them, one could decipher more information about supernatural systems and even obtain unique supernatural products from within.
The reason why the merchandise at Supernatural Home was so diverse.
Was largely due to the items obtained from Boundary Ruins.
However, the appearance of Boundary Ruins wasn't always a good thing. Some were highly dangerous, not only difficult to profit from but also capable of causing harm to the surrounding areas.
Xu Xi was now facing such a special situation.
“It's a Boundary Ruins from the cultivation side.”
In the suburbs of Yanshan City.
After receiving Zhang Yaoguo's transmission.
Xu Xi rushed to the scene as quickly as possible.
From afar, the azure sky was shrouded in blood rain, with mountains of corpses and seas of blood faintly visible in the rain, filled with nameless terror and overwhelming horror.
It was hard to imagine how many people had died within the Boundary Ruins.
To create such a hellish domain.
Xu Xi could vaguely see that the attire of some corpses within the Boundary Ruins resembled the clothing of cultivators he was familiar with.
“Could the origin of this Boundary Ruins be the cultivation world I simulated?”
“No, not necessarily. There are many cultivation worlds.”
Xu Xi gazed into the distance.
Observing for a long time.
Then he turned to Zhang Yaoguo beside him: “What's the current situation?”
“Very bad,” Zhang Yaoguo's expression was grave, his face looking particularly grim. “This Boundary Ruins appeared an hour ago, and its expansion speed is very fast. If this continues, it will soon reach Yanshan City proper.”
“I've already requested reinforcements from the headquarters. Until then, we can only rely on ourselves.”
Zhang Yaoguo's voice grew heavier.
Full of vigilance, trepidation, and oppression.
The director of the Yanshan City Supernatural United Bureau, a middle-aged man who had dedicated most of his life to the country, unconsciously clenched his fists and stared at the indescribable scene of the Boundary Ruins.
The Boundary Ruins before them were too terrifying, with continuous blood rain and ghostly wails echoing.
Just a glance at the mountains of corpses and seas of blood within.
Would cause those with weak wills to lose the courage to confront it.
What was more critical was that Xu Xi sensed a large amount of ghostly aura within, likely giving birth to some malevolent beings or perhaps the souls of the deceased cultivators had turned into ghost cultivators.
“This is troublesome...”
Xu Xi narrowed his eyes slightly. Although he was skilled at defeating enemies above his rank and his Withering Vine Sword was effective against ghosts, there was still a limit to its power.
The Blood Rain Boundary Ruins before him was simply too vast.
It was unclear which demon had created such an exaggerated mountain of corpses and sea of blood.
Fortunately, although the yin energy was astonishing, it was still within acceptable limits. Even if he couldn't eliminate the Boundary Ruins, Xu Xi could still escape safely with his abilities.
Thinking of this, Xu Xi said to Zhang Yaoguo: “Have those below Foundation Establishment leave.”
“This event is too dangerous. Only those at Foundation Establishment or above have the ability to protect themselves within the Boundary Ruins.”
“Alright!” Zhang Yaoguo responded decisively. “You're a Golden Core Cultivator, more familiar with cultivation-side Boundary Ruins than us. You decide on this.”
Soon.
More than half of the gathered supernatural beings dispersed.
Those who remained.
Were all at the Foundation Establishment level or equivalent, such as Innate Martial Artists or formal mages.
Supernatural beings at this level had already moved past the novice stage and could freely utilize their powers.
Making them reliable combatants.
Additionally.
Given the excessive threat posed by this Boundary Ruins, as the director, Zhang Yaoguo had also summoned another top-tier combatant from the Yanshan City Supernatural United Bureau.
An expert in the Blood Qi Martial Path, equivalent to a Golden Core Cultivator.
Wang Dali.
A man who looked quite tall and muscular.
“Hahaha, my super wisdom is telling me it's time to use my super strength to save the world!”
With a tall and robust build, powerful arms, and a steady stride like a heavy truck moving forward.
Wang Dali laughed loudly.
His voice booming like a drum.
He walked up to Xu Xi, revealing a mouthful of white teeth, and said heartily: “Long time no see, Xu brother.”
Xu Xi nodded: “Long time no see.”
Xu Xi and Wang Dali weren't meeting for the first time.
Over the past month, they had crossed paths a few times at the Supernatural United Bureau.
To be honest, Xu Xi had a good impression of this burly man. He was honest and upright, with a strong martial aura.
Perfectly embodying the essence of the Blood Qi Martial Path.
...
After a brief rest on the spot and confirming the battle preparations, all the supernatural beings from the Yanshan City Supernatural United Bureau followed Xu Xi's lead and approached the Boundary Ruins.
As the distance shortened.
The horror of the mountain of corpses and sea of blood became more apparent.
The sky and earth were dyed crimson, stinking and foul. Red blood rained from the sky, quickly forming small puddles, which were filled with softened corpse limbs.
Tendons intertwined, hair tangled, and bone fragments deeply embedded in rotting flesh.
“Ugh——!!!”
In the team of supernatural beings.
Someone with weaker mental fortitude suddenly widened their eyes, clutching their chest and vomiting violently.
The scene before them was too challenging to one's sense of reality.
One after another, broken and mutilated corpses were piled into towering mountains of corpses, emitting an unimaginable stench.
Hatred, shock, anger, fear.
Countless complex emotions were displayed on those blurred, rotten faces.
Making it impossible to imagine what had happened.
“Die——! Die——!”
Suddenly, a corpse filled with overwhelming hatred moved, roaring and lunging at the crowd. Ghostly spirits of deceased cultivators also grinned malevolently, attempting to possess the bodies of the supernatural beings.
Under Xu Xi's vigilance.
These evil spirits were directly slain by him.
However, Xu Xi's confusion deepened.
Xu Xi crouched down, pulling out a cultivator's robe from the blood water, his brows furrowed.
This robe was too familiar. At the end of his first simulation, the demonic cultivators who had opposed him were wearing similar clothes.
If he remembered correctly, they belonged to a sect called the Celestial Demon Cult.
“Is there a problem, Xu brother?”
Wang Dali asked while on guard.
“No, it's nothing. Let's keep moving.”
Xu Xi shook his head and continued leading the team forward.
As they delved deeper into the Boundary Ruins, they used their respective supernatural powers to clear away the blood and corpses, preventing a vicious cycle that could contaminate the outskirts of Yanshan City.
But soon.
Xu Xi made another unexpected discovery.
In a pool of blood, he found the body of a Heavenly Sword Sect cultivator. Both the attire and the badge on the waist matched his memories perfectly.
A bold guess emerged in his mind.
“Is this the battlefield between the Heavenly Sword Sect and the Celestial Demon Cult?”
“The origin of this Boundary Ruins is the cultivation world I simulated!?”
