A mountain cave in the White Bone Sect's territory was named the Demon Sealing Cave. Its entrance was perpetually sealed by a grand formation, rendering it inaccessible to outsiders.
At this moment, Xiao Fei and Zhu Yu had stealthily approached the entrance of the Demon Sealing Cave.
A male corpse lay at the cave's entrance, a bloody hole in its chest still oozing hot blood. Xiao Fei searched the corpse and found a storage bag, which he waved at Zhu Yu.
"A storage bag from a mere Foundation Establishment cultivator, you probably wouldn't fancy it!"
"Who says I wouldn't? You have to give me half!"
Xiao Fei inwardly grumbled. He had managed to latch onto such a powerful figure, yet this person still wanted to split such meager gains with him. He could only divide the valuable items within the storage bag into two portions.
However, Xiao Fei kept the corpse for himself. This time, Zhu Yu didn't argue with him, fearing it might be smashed into his hands again.
In reality, Zhu Yu didn't lack such wealth. He simply found Xiao Fei displeasing and didn't want him to profit.
After killing the cultivators guarding the Demon Sealing Cave and dividing the spoils, the two turned their attention to the formation at the cave's entrance.
Xiao Fei took out the jade slip given to him by Old Ancestor Shangguan and reread it. The jade slip provided several methods for breaking the formation, each with its own advantages and disadvantages.
Having been trapped at the bottom of a canyon for decades, he had laid a solid foundation for his understanding of formations. With the guidance from Old Ancestor Shangguan, breaking this formation was not difficult.
Next, several formation plates appeared in his hand, which he placed around the cave entrance. The formation plates activated, emitting beams of light.
The light shone upon the formation at the entrance of the Demon Sealing Cave, gradually merging with it, and then creating an opening just large enough for one person to pass through.
A wave of cold demonic energy surged out from the opening, causing Xiao Fei to shiver involuntarily.
"Let's go!"
Xiao Fei turned and shouted at Zhu Yu, but he himself did not move. After a while, he saw that Zhu Yu also hadn't moved.
"I've never seen a Golden Core cultivator as timid as you! True braves can cast aside life and death and face all unknown risks head-on!"
Xiao Fei's face showed a look of disdain. He released a zombie, which roared and unhesitatingly drilled into the entrance.
"Look! Even this zombie is braver than you!"
"Why don't you go in yourself?"
Zhu Yu retorted.
"Roar, roar, roar... Crunch, crunch!"
This brave and fearless zombie entered the Demon Sealing Cave. After only a few roars, its voice abruptly stopped. The sound of crunching, like something devouring its prey, emanated from within.
Both their expressions darkened, making them even more hesitant to rush in.
Xiao Fei released two more zombies this time and sent them into the cave again.
"Roar, roar, roar... Crunch, crunch..."
This time, the two zombies lasted a bit longer, about three to five breaths, before falling silent.
Xiao Fei estimated the time and released five zombies simultaneously. This batch should last for more than ten breaths, enough for them to enter and scout. If things went south, they would still have time to retreat.
"Enter together!"
The two nodded and followed behind the five zombies, passing through the sealing formation one by one and entering the Demon Sealing Cave.
Upon entering the Demon Sealing Cave, Xiao Fei immediately summoned the tortoise shell shield gifted by Old Ancestor Shangguan to block in front of him, shielding himself completely before beginning to survey the situation inside the cave.
The cave was filled with demonic energy, entirely different from the spiritual energy of the cultivation world. Absorbing this demonic energy into the body stirred up a sense of restlessness and bloodlust.
Xiao Fei quickly circulated his "Primordial Five Elements Technique," holding his mind steady.
At this moment, his zombies were battling a black demonic ape.
The demonic ape was powerfully built and tall, its eyes crimson. Two pairs of sharp fangs were still adorned with shreds of zombie flesh.
With a "crunch," a zombie's skull was bitten open by the demonic ape. The zombie's tough physique seemed fragile under the ape's teeth.
Then, its tongue flicked out, and with a "slurp," it devoured the zombie's brain.
Xiao Fei watched the zombies on the ground with their brains eaten, thinking that karma could be a bitch, and zombies could also have their brains eaten.
"Zhu Yu, ready to fight?"
"Let's do it!" Zhu Yu replied without hesitation.
At this critical moment, the two quickly reached a consensus, unified their opinions, and immediately drew their weapons, preparing for battle.
Xiao Fei possessed many spirit artifacts, all obtained from dead evil cultivators in the past, and several of them were quite powerful treasures.
However, in his daily battles, he rarely fought personally, always letting his zombies and Iron Fire Ants take the lead.
Today was no exception. He released a swarm of zombies and Iron Fire Ants to entangle the demonic ape, restricting its movement, while he himself summoned the tortoise shell shield and hid behind them.
Seeing Xiao Fei's minions successfully entangle the demonic ape, Zhu Yu, with great tacit understanding, summoned his flying sword. A flash of light streaked across, and the demonic ape's head rolled to the ground.
This demonic ape didn't seem particularly strong, likely a bit weaker than a Golden Core cultivator.
After the demonic ape's head landed on the ground, Xiao Fei was about to step forward to investigate when he noticed that both the ape's body and head were dissipating.
In just a few breaths, the entire demonic ape's body had turned into pure demonic energy and vanished into the air, leaving no trace behind.
The Demon Sealing Cave was filled with pure demonic energy, which was an invaluable treasure for cultivators practicing demonic arts.
There were very few places on the entire Eastern Continent where such pure demonic energy could be found, and these places were invariably occupied by evil cultivators or demonic sects.
The interior of the Demon Sealing Cave was a narrow, winding passage. The cave contained only demonic energy, with no spiritual energy whatsoever.
For cultivators practicing righteous arts, this demonic energy could not be absorbed and refined; instead, it was quite harmful to the body.
Xiao Fei attempted to absorb a bit of the demonic energy and refine it using the "Primordial Five Elements Technique."
After a moment, he once again marveled at the genius of the creator of the "Primordial Five Elements Technique," Old Ancestor Primordial.
The Primordial Five Elements Technique could refine demonic energy into one's own magical power.
However, with his mediocre aptitude, absorbing demonic energy was still a strenuous task, no better than holding a spirit stone.
Within the cave grew several spiritual plants imbued with dense demonic energy. Xiao Fei dug up a few, intending to plant them in his spatial realm to see if they would grow.
The two proceeded along the Demon Sealing Cave and encountered dozens more demonic apes, all of whom were slain by their combined efforts.
Approximately an hour later, a stone tablet stood before them, inscribed with the three characters "封魔井" (Feng Mo Jing - Demon Sealing Well).
Behind the stone tablet was a deep well, its opening protected by layers of formations.
"Is this the passage to the otherworldly demonic realm?"
Zhu Yu stood at the well's edge, observing it with curiosity.
"But finding this well is useless, isn't it? How can you prove the White Bone Sect's collusion with the demonic race?"
Xiao Fei displayed a profound smile, as if everything was under his control.
"Youngsters shouldn't be so rigid! You need to be bolder, more open-minded. If you don't have evidence, you can create it yourself!"
"You intend to frame them?"
Zhu Yu, already no paragon of virtue, instantly grasped Xiao Fei's intention. This was likely also the instruction from their respective old ancestors.
"Don't put it so crudely. The evil cultivators of Eagle Mountain Kingdom have harbored such thoughts subconsciously, they just haven't expressed them."
As Xiao Fei spoke, he took out several projection mirrors and set them up around the Demon Sealing Well, preparing to fabricate evidence.
These magical artifacts could accurately record visual data, much like cameras.
"Lend me the corpse of the White Bone Sect's Golden Core cultivator."
"That's my spoils of war!"
"I'll return it after using it!"
Zhu Yu threw the corpse onto the ground. Although this corpse had not been refined, it could still be manipulated somewhat using corpse-controlling techniques.
Just as Xiao Fei was about to manipulate the corpse to create evidence, a formation on the Demon Sealing Well automatically split open, revealing a thin crack, and an inconspicuous black light flashed.
The two, who were preparing to fabricate evidence, did not notice this change.
Xiao Fei bent down to fiddle with the corpse on the ground, and Zhu Yu also leaned over to watch.
Xiao Fei casually looked up and found Zhu Yu to be incredibly beautiful, more so than any woman, and couldn't help but swallow his saliva.
He looked down again and found Zhu Yu's alluring and exquisite face lingering in his mind, refusing to leave.
He wasn't very learned, so he could only repeat in his heart, "Damn! So beautiful! Damn! So incredibly beautiful! Damn..."
At this moment, he had somehow crossed the boundaries of gender and harbored improper thoughts towards Zhu Yu!
Simultaneously, some changes were also occurring in Zhu Yu's mind.
The more he looked, the more he felt Xiao Fei resembled his first master. A sense of disgust, and even hostility, gradually grew in his heart towards Xiao Fei.
Especially Xiao Fei's gaze, which felt very wrong, reminded him of the humiliation he had suffered at his first master's hands.
Various negative emotions surged into Zhu Yu's heart, and he secretly prepared to deliver a fatal blow to Xiao Fei.
Amidst this eerie atmosphere, a pair of eyes quietly observed the two from the shadows.
