Although the ancient city's space was quite large compared to the outside world, it was still created by a Dou Sheng, so the distance was limited.
In just half an incense stick's time, Xiao Yan flew to the Yin-Yang Divided Dried Riverbed.
"The Dark Side is just ahead," Xiao Yan stopped, looking up at the Yin-Yang Evil Saint floating in the sky.
"I heard that no one who has been tainted by this place's aura has ever come out unscathed; they all turn into killing machines."
"Just go. Does a genius of the Xiao Clan only have this much courage?"
"Having courage without brains makes you an idiot."
"Given my relationship with the young master, I'll naturally protect you."
In the end, Xiao Yan still chose to enter this dark, dense fog.
Just looking at this black fog was enough to make someone feel agitated and filled with murderous intent. It was hard to imagine how terrifying it would be to be touched by it.
As soon as Xiao Yan entered the black fog, his vision turned completely black, and his field of view shrunk drastically.
"Use your Soul Force. With your Grade 7 mid-level Soul Force, you should still be able to use it here," the Yin-Yang Evil Saint's voice sounded from behind him.
Xiao Yan's body paused slightly, and his vast Soul Force was released.
Although his Soul Force was also hindered after coming into contact with the black fog, he could at least sense the space within a hundred feet around him.
"Follow this path in front of you," the Yin-Yang Evil Saint's soul floated in the sky, seemingly unafraid of the fog, and constantly guiding Xiao Yan.
However, as his Soul Force gradually interacted with the black fog, Xiao Yan felt waves of violent and murderous emotions constantly seeping into his soul.
Gradually, his eyes turned blood red.
"Not bad. To have lasted this long, your Soul Force is indeed a very solid Grade 7, and your will is much more resolute than I imagined," the Yin-Yang Evil Saint chuckled.
"Stop with the jokes. I'm about to collapse," Xiao Yan gasped, the violent killing intent having already seeped into his soul, gradually influencing his will.
He now felt an increasing urge to tear everything before him to shreds, a desire to destroy everything.
Even he wasn't sure how much longer he could hold on before he lost it.
"I can't hold on any longer. I'll be lost if I don't leave now." Feeling the last vestiges of his sanity, Xiao Yan prepared to retreat.
"Don't retreat." The Yin-Yang Evil Saint's voice echoed. A ray of Pure Light shot out from his soul body, unaffected by the black mist, and landed within Xiao Yan's body.
The instant the Pure Light entered Xiao Yan's body, his soul, which had been tainted by the black mist, was instantly cleansed. The violent emotions within Xiao Yan's soul rapidly faded, and an unprecedented clarity remained in his mind.
"My Soul Force has become even purer," a hint of joy appeared on Xiao Yan's face, but when his Soul Force sensed the Yin-Yang Evil Saint, he found that the other party's soul had visibly weakened.
"Senior." Xiao Yan finally felt a sliver of respect for him.
"Hehe, I was already a dead man. Using this remaining Soul Force to cultivate a successor was always part of the plan. No need to thank me," the Yin-Yang Evil Saint's voice was filled with a sense of detachment.
"Keep going forward. You are about to uncover a truly terrifying secret!" There was something in the Yin-Yang Evil Saint's voice.
"What secret could scare me, the Imperial Son of the Xiao Clan? Is it a Dou Di powerhouse? I've even seen a living Dou Di, let alone some Dou Di secret," Xiao Yan scoffed, and continued forward.
Every few steps, he felt the violent killing intent in his heart swell again. But each time he neared his limit, the Yin-Yang Evil Saint behind him would always provide a timely burst of Pure Light.
After a few times, Xiao Yan felt his Soul Force become purer. This wasn't an increase in quantity, but a qualitative leap.
If he cultivated diligently for a year or two, he would probably break through to Grade 7 high level.
And with the release of these few bursts of Pure Light, the Yin-Yang Evil Saint's soul became a bit more ethereal.
Each beam of Pure Light refining Xiao Yan's soul was a source of his Soul Force.
Finally, after passing through the endless black fog, a ray of light appeared before Xiao Yan.
Before him, there was another identical Yin-Yang Altar.
However, the scene within the altar made Xiao Yan's scalp tingle.
Inside the Yin-Yang Altar, a monster over two meters tall was sitting in the center.
This monster was covered in red fur, and his limbs were swollen and bulging. His nails were sharp and black. His face was terrifying, like a demon from the abyss.
The most unsettling thing was that his blood-red eyes were staring at you.
The moment he locked eyes with those eyes, a chill rose from the depths of Xiao Yan's spine. Through those eyes, he seemed to see endless strangeness and ominousness.
The next moment, streaks of red fur began to sprout from his body.
"Roar!" Xiao Yan let out a low roar, and bone spurs began to protrude from his fingers, gradually transforming into claws.
"Wake up!" The Yin-Yang Evil Saint's voice rang out behind his ear, and another beam of Pure Light descended.
After his soul was washed by this Pure Light, Xiao Yan regained his clarity and looked at the red-haired monster with a gaze full of wariness.
Just a corpse could cause such strange things to happen to him. This unknown fear was often more terrifying.
However, when he looked at the top of the ancient monster's head, he found two fish, one black and one white, swimming around.
"Yin… Yin-Yang Twin Flames?" A look of astonishment appeared on Xiao Yan's face.
"That's right. This one is the real Yin-Yang Twin Flames." The Yin-Yang Evil Saint's voice chuckled.
"What about the Yang side?"
"That's also a Yin-Yang Twin Flame!"
"You actually have two Yin-Yang Twin Flames?" Xiao Yan looked at the Yin-Yang Evil Saint with some surprise.
"No, the Yin-Yang Twin Flame on the Yang side is indeed real, but it's just a Lesser Flame."
Pausing, a strange smile appeared on the Yin-Yang Evil Saint's face. "A special Lesser Flame."
"So, the one you gave the Yao Ling was a fake?"
"You could understand it that way." The Yin-Yang Evil Saint smiled slightly. "Let's not worry about that for now. I think you should focus on the crisis at hand."
"Crisis at hand?" Xiao Yan was slightly taken aback. When his gaze swept over the Yin-Yang Altar, he unexpectedly found that the bizarre monster was slowly standing up.
In an instant, Xiao Yan's scalp began to tingle.
"What, what kind of monster is this? If it comes out, wouldn't I be dead?!"
"This is..."
After a moment of silence, a complex and hesitant expression appeared on the Yin-Yang Evil Saint's face.
"This is my corpse!"
