This kind of technique is simply about killing without a trace.
Zhou Yan's eyes narrowed, revealing intense greed. Then, with a thought, he prepared to integrate this "Black Demon Technique" into his body.
But just then, a cold voice suddenly rang out.
"Hmph! The 'Black Demon Technique' is the treasure of my 'Black Demon Sect.' How can you, a despicable wretch, dare to covet it?"
This cold voice echoed in Zhou Yan's mind. At that moment, Zhou Yan felt as if his head would explode. The intense pain made him gasp involuntarily. He suddenly raised his head and looked around, but saw nothing.
"Who?"
Zhou Yan grunted, his face turning extremely grim, his eyes flashing with cold light. He had just sensed someone eavesdropping on his secret, which filled him with immense anger.
"Heh heh, in this world, who is there to be?"
A mocking voice came from the stone slab. Immediately, an old man in green appeared before Zhou Yan. His face bore a smile, but within that smile lay a profound killing intent that made it impossible to meet his gaze.
This old man wore a green robe and was hunched over, yet his stance exuded an extraordinary tenacity.
This old man was the sect master of the Black Demon Sect, Zhou Yan!
Seeing Zhou Yan appear, Zhou Yan's pupils constricted, his gaze slightly narrowing. Terror flickered in his eyes. He had heard of figures like Zhou Yan before and never expected him to appear here.
"Zhou Yan, what do you want?"
Zhou Yan's brows furrowed tightly. He knew very well that given Zhou Yan's personality, he would absolutely not allow anyone else to obtain such a heaven-defying technique as the "Black Demon Technique." Moreover, Zhou Yan possessed the strength to do so.
"Heh heh, Zhou Yan, this is the cave mansion of the 'Black Demon Technique.' Since you've entered, you are a disciple of our 'Black Demon Sect.' As a disciple, you should abide by the rules."
"Isn't what you're saying a bit ridiculous? Is the 'Black Demon Technique' yours?"
A mocking smile appeared on Zhou Yan's face.
"Hmph! The 'Black Demon Technique' is the treasure of my 'Black Demon Sect.' It's not something anyone can simply control!"
"Furthermore, we in the 'Black Demon Sect' have always decided everything by strength. Without formidable strength, one is simply unworthy of possessing the 'Black Demon Technique'!"
"And you, though you possess a remnant of the 'Black Demon Technique,' your talent is limited. At best, you can cultivate to the sixth level of Martial Master. If you truly disagree, I can give you an opportunity."
A hint of a smile played on Zhou Yan's lips, his eyes revealing a mocking glint.
"What opportunity?"
A sharp glint flashed in Zhou Yan's eyes, his body trembling uncontrollably, his heart racing.
"Of course, it's the 'Heavenly Gang Overlord Fist'! I can teach you the 'Heavenly Gang Overlord Fist,' and directly boost your combat power to the Martial King realm!"
Zhou Yan said with a playful smile.
The "Heavenly Gang Overlord Fist" was a top-tier boxing technique, a low-grade Earth-tier martial art. Zhou Yan himself was at the peak of the eighth level of Martial Master.
Moreover, Zhou Yan possessed a Five Elements Core, a type of core extremely rare in the outside world.
Therefore, after Zhou Yan broke through to the Martial Emperor realm, his physical body would undergo a leap in growth.
And Zhou Yan's core was of the Five Elements attribute, making his combat power even more terrifying!
As Zhou Yan's words fell, Zhou Yan's eyes suddenly lit up: "Really? You would actually teach me your martial skill?"
Zhou Yan knew very well that martial skills were top-tier items throughout the Southern Region. Under normal circumstances, unless encountering an extremely significant opportunity or under special conditions, they would absolutely not be easily taught.
Yet, Zhou Yan claimed he would teach it to him.
Considering that Zhou Yan was a Martial Emperor, if he taught it to him, wouldn't his combat power double?
A wave of ecstasy surged within Zhou Yan.
Zhou Yan's hands trembled incessantly, this ecstasy almost making him lose control.
"Of course, the condition is very simple: you must obey my commands," Zhou Yan said with a smile.
"I am willing to serve you."
Zhou Yan's eyes were filled with fervor. His body felt somewhat weak at this moment. In the face of such a powerful individual, he had no trace of arrogance left and could only obey orders.
"Good."
A smile appeared on Zhou Yan's lips. Then, with a wave of his right hand, the dark elemental power from the stone slab instantly dissipated.
This scene caused Zhou Yan's pupils to contract violently, a shock flickering in the depths of his eyes.
It was then that Zhou Yan understood why Zhou Yan had kept him and even brought him here.
It turned out that Zhou Yan had already made his plans.
Zhou Yan had seen his potential, and that was why he had kept him.
However, in a place like this, it would be extremely easy for Zhou Yan to kill him.
Therefore, in Zhou Yan's opinion, Zhou Yan had kept him entirely to threaten others.
"Zhou Yan, I have now successfully cultivated the 'Black Demon Technique.' I believe you have no reason to stop me anymore, right?"
Zhou Yan took a deep breath, calming his excited emotions. His gaze was filled with a burning intensity.
"Of course, there is no reason. I am very satisfied with your strength. Therefore, I will now arrange a position for you. Come with me somewhere."
Zhou Yan nodded, then turned his head to look at the two figures in the distance, a mocking smile slowly rising to his lips.
"You two, come here!"
As Zhou Yan's voice fell, the two figures hurried over, fear in their eyes.
After running over, they quickly prostrated themselves before Zhou Yan and Zhou Yan.
"Great hero Zhou Yan, spare us! We beg you, we are both loyal servants of Great hero Zhou Yan!"
"Yes, yes, we are both already under the control of Great hero Zhou Yan. Now, whatever Great hero Zhou Yan asks us to do, we will do it willingly without resistance."
"We are both puppets of Great hero Zhou Yan, at Great hero Zhou Yan's beck and call!"
The two knelt on the ground, their faces mournful, appearing utterly tragic.
"Hmm?"
Hearing their words, Zhou Yan was slightly stunned. Then, his gaze fell upon their chests, where he saw two bloody gashes, fresh blood flowing out from them.
