God-Demon Body Refining Art

"Although you're strong, pull-ups aren't just about brute force," Jiang Yingqing said, looking at Ling Yun as he walked under the horizontal bar. She tilted her chin up slightly, a hint of challenge in her voice. "Even if you can't do a single one, I promise I won't laugh at you."

Ling Yun just smiled at her, not replying. He leaped up lightly, his hands gripping the bar firmly.

His initial movements were textbook perfect, neither too fast nor too slow. With every rep, his chin cleared the bar, his body as steady as a rock.

One, ten, twenty… He completed thirty standard pull-ups in one go, as easy as taking a stroll.

Immediately after, he switched to one-handed!

His left hand gripped the bar, and he pulled his entire body up and down using only the strength of that single arm.

His arm muscles bulged, yet his movements maintained an astonishing stability and rhythm. Another twenty reps!

And he wasn't done yet! Just as everyone thought he'd reached his limit, Ling Yun released his left hand and hooked the bar with only his right pinky finger!

He took a deep breath, his core muscles tensing suddenly. Using only the strength of his pinky, he slowly pulled his body up and down again! One, two… a full ten reps!

Each pull-up seemed to defy the laws of physics, making the onlookers' hearts pound.

After finishing, Ling Yun landed lightly, his face unreddened, his breathing unfazed. Not a single bead of sweat graced his forehead, as if he had merely stretched.

He clapped his hands, feeling that continuing further would be truly bullying.

The entire sports field fell silent.

Everyone seemed frozen, mouths agape, eyes wide, their brains struggling to process the superhuman display they had just witnessed.

"Just as I expected," Zhou Da was the first to break the silence. He crossed his arms, wearing an infuriatingly smug "I knew it" expression. His voice boomed, cutting through the quiet. "The protagonist always makes a dramatic entrance! Standard procedure, don't overthink it!"

His shout was like pressing play, and the crowd instantly erupted in a "buzz"!

"Holy crap! Holy crap! Holy crap!"

"One hand?! Pinky finger?! Am I dreaming?"

"Is this even human?!"

Most of the students were simply stunned, but they didn't fully grasp the terrifying implications.

Niu Li and Jiang Yingqing, who had some experience, had completely changed expressions. Their faces showed the horror of someone who knew the hellish difficulty involved.

"Brother Yun… he did twenty one-handed pull-ups?! It's a struggle for me to do ten with both hands!" Niu Li's voice trembled, his gaze towards Ling Yun filled with awe.

Jiang Yingqing also took a deep breath, pointing at the horizontal bar and explaining to her shocked classmates, "Do you know what this means? Thirty standard pull-ups are the peak for an ordinary person; twenty one-handed is monster-level! As for the pinky finger… that's no longer about strength. It's absolute dominance over body control, core stability, and the limits of finger strength! This is simply not something a human can do!"

"Good lad!" Instructor Cheng Yuanzhou finally recovered from the immense shock. He strode up to Ling Yun, clapping him forcefully on the shoulder, his eyes looking at him as if he were an alien. "How… how do you usually train? Even in the army, I've never seen such a fierce soldier king!"

Ling Yun offered an "innocent" smile. "Reporting, Instructor. I just train regularly, and… maybe I'm naturally a bit stronger? It just happened as I trained."

He attributed everything to talent and effort, a reasonable and flawless explanation.

Cheng Yuanzhou was skeptical, but besides "extraordinary talent," he couldn't find a more logical explanation. He could only shake his head in admiration.

Ling Yun's gaze shifted to the still stunned Jiang Yingqing. A mischievous smile played on his lips as he walked over. "Beauty Jiang, what do you think? Were you completely shocked by my heroic and magnificent physique just now? Are you now filled with endless admiration for me?"

He deliberately leaned his face a little closer.

"Pfft! Who admires you!" Jiang Yingqing snapped back to attention instantly, her cheeks flushing. She glared at him indignantly. "So you're a bit stronger and have freakish body control! What's so great about that! If you've got guts…"

Her eyes darted, and an idea struck her. "If you've got guts, come rock climbing with me! The military training ends soon, and I'm going to Qingmang Mountain to free solo climb during the holiday! Do you dare?"

"Sure," Ling Yun agreed immediately without thinking, his answer crisp and decisive.

It just so happened that he hadn't figured out how to save Jiang Yingqing yet, and now he had a reason.

This prompt acceptance actually surprised Jiang Yingqing.

She had expected Ling Yun to hesitate, but she hadn't anticipated him agreeing so readily.

However, she quickly attributed it to Ling Yun's boundless confidence and snorted, "Fine! It's a deal then! On the morning of the first day of the holiday, I'll have my driver pick you up!"

"It's a deal."

After lunch, Ling Yun didn't take a nap. Following his memories from his past life, he went to an abandoned classroom.

The midday sun streamed through the dusty windows in several shafts of light. Ling Yun found a seat by the wall and mentally chanted, "Claim system rewards!"

His palm grew heavy, and four black pills, the size of dragon eyes and emitting a strange herbal fragrance, appeared out of thin air.

[Body Tempering Pill: A sacred pill for body tempering. It can greatly alleviate the pain of body tempering, shorten the tempering time, and has no side effects.]

[God-Demon Body Refining Art (Qi Refining Chapter): A supreme body refining technique originating from innate gods and demons. Unrivaled in physical strength at the same level. Cultivating it to great accomplishment allows the body to achieve sainthood and become indestructible through countless tribulations!]

Looking at the system descriptions, Ling Yun didn't hesitate and swallowed a Body Tempering Pill.

The pill melted in his mouth, transforming into a vast yet gentle stream of warmth that instantly swept through his limbs and bones!

He immediately began circulating the God-Demon Body Refining Art according to the profound meridians in his mind.

In an instant, he felt his bones, muscles, skin, and internal organs all let out joyful cries!

Wherever the warm current passed, his cells were undergoing frantic transformation and reorganization. Impurities were gently refined and expelled, and strength surged and condensed within his body like an unleashed flood.

This was the first time he had circulated the cultivation technique, and the route was a bit stiff. It took nearly an hour to completely absorb the energy from one Body Tempering Pill.

He could clearly feel that his physical strength had undergone a qualitative leap!

With every movement, he contained explosive power.

"Hoo..." Ling Yun exhaled a breath of stale air, carrying a faint gray impurity.

Unfortunately, time was pressing, and he didn't have time to savor this transformative change. He quickly tidied himself up, confirmed there was nothing unusual about his body, and then hurried back to class.

"Brother Yun, where did you run off to? Your face is a little pale, didn't take a nap?" Zhou Da asked curiously as he watched Ling Yun approach. Many other students had also woken up.

Ling Yun's expression didn't change. He clutched his stomach, feigning pain, "Don't even mention it. The cafeteria food at noon... gave me an upset stomach, I had to run to the restroom several times."

"Ah!" Zhou Da and several other students who overheard immediately showed expressions of deep empathy. "Cafeteria food, you know how it is! It's a good thing you didn't collapse, shows you have a good constitution!" This excuse, given the "notorious reputation" of the high school cafeteria, was virtually foolproof.

The afternoon's military training session was on how to fold quilts. Since the day students didn't have dormitory bedding, the instructor Cheng Yuanzhou took the boarding students back to the dormitories, leaving the day students to their own devices on the sports field.

Ling Yun's eyes lit up—a heaven-sent opportunity! He subtly slipped away from the crowd and, familiar with the way, made his way back to the abandoned, empty classroom, locking the door behind him.

With the experience from last time, he was now proficient. He sat down cross-legged and, without hesitation, swallowed the remaining three Body Tempering Pills in one go!

Boom—!

Three torrents of potent medicinal energy erupted simultaneously, like three furious dragons charging and surging within his body! The circulation route of the God-Demon Body Refining Art was now incredibly clear. He sank his consciousness and fully guided this surging energy to impact every inch of his body.

His bones and muscles chimed like clashing metal, his blood flowed like a great river, and countless tiny bolts of lightning seemed to course beneath his skin. This time, the refining speed was greatly accelerated!

In less than two hours, the violent medicinal power was completely subdued, absorbed, and integrated into every cell of his body.

[Ding! Congratulations to the host, the Qi Refining chapter of the God-Demon Body Refining Art has been cultivated to the Great Perfection realm!]

The system's prompt carried a subtle hint of admiration.

Ling Yun opened his eyes, a sharp glint flashing within them before quickly returning to a composed state.

He felt the earth-shattering changes within his body, his heart filled with shock.

According to the memories of the cultivation technique's inheritance, for an ordinary person to cultivate the Qi Refining chapter to Great Perfection, even those with exceptional talent would need at least ten years of arduous effort!

But he had only used three pills and less than three hours!

"This cheat... " Ling Yun grinned silently. This system was truly a divine artifact for altering one's destiny!

"System, what are my current physical attributes specifically?" He needed to quantify this terrifying power.

[Host's Current Physical Attributes:]

[Single Arm Burst Strength: Approximately 2000 kg]

[Maximum Sprint Speed: Approximately 100 m/s]

"Hiss..." Even though Ling Yun had prepared himself mentally, he still gasped in shock at these figures. One hundred meters per second? Two tons of arm strength? This was no longer human peak; this was a full-fledged human-shaped Tyrannosaurus Rex!

This morning he was at the limit of a mortal; now he had stepped into the realm of the superhuman!

He moved his limbs, feeling as if his body was weightless yet contained world-destroying, terrifying power. He controlled it perfectly, with not a trace of aura leaking out.

When he returned to the sports field again, the day students were chatting in small groups.

"Ling Yun! Where did you disappear to again?" Jiang Yingqing spotted him immediately and walked over to ask, her eyes filled with curiosity.

Ling Yun's acting skills were on point. He immediately put on a "still shaken" expression, clutched his stomach, and sighed, "Ah, don't even mention it. I guess the 'aftereffects' of the cafeteria food at noon haven't passed yet... I had to go again."

Upon hearing this, Jiang Yingqing's pretty face immediately scrunched up in disgust. She waved her hand and said, "Ew... I originally wanted to try the cafeteria food after hearing them talk about it, but now... I wouldn't go even if you beat me to death!"

As the two were talking, a male student walked towards them.
