All around, the screams of the Mount Hua disciples trapped in the sonic frequency trap echoed like a chaotic cacophony of destruction. Seventy percent of Yoe Choin and Baek-Un's premeditated demolition plan had succeeded. The Mount Hua disciples, who usually moved as light as feathers, now lay prostrate, the meridians in their feet in disarray from the resonance of the Black Iron bells embedded underground.
However, amidst the chaos, Elder Han-Seung stood tall. As a Mastery stage practitioner, he was a structural exception. His thin sword radiated a dense plum blossom light, creating its own energy isolation zone that repelled the frequency vibrations from the Evernight soil.
"Moen Kang Yo... you're wasting your time with this mechanical toy,"
Han-Seung hissed, his voice clear even amidst the dust storm.
"This structure will still collapse when its central pillar... you... is destroyed by my hands."
Under his black robe, Moen Kang Yo's body trembled. Not from fear, but from a high-pressure valve within his soul reaching its maximum.
"Foreman... open the valve,"
The voice of the real Moen Kang Yo growled in my inner space, its voice as deep as a bottomless pit.
"Your logic has brought me this far. You've set the stage, you've polished my weapons, and you've given this body a density I never imagined. But now... this isn't about calculating weights anymore. This is about pure killing intent."
Yoe Choin took a deep breath within their consciousness space. His glowing blue eyes scanned Elder Han-Seung one last time before handing over control.
"Listen, Boss Demon,"
Choin said calmly.
"I'll hand over full operational clearance to you. Use this Level 3 Internal Finishing, which I've poured with high-quality concrete, to the best of my ability. But remember, don't let your Qi flow overflow to the point of damaging our pipeline meridians. I'll remain here as the K3 supervisor. If I see your soul starting to crack with madness, I'll close the valve by force."
"Heh... you're a talkative supervisor, Foreman,"
Kang Yo replied.
"But I need your precision to ensure every blow of my sword lands precisely at the material's fatigue point."
In the next instant, the aura surrounding the young man's body changed completely. The blue color of the Blueprint in his eyes was slowly obscured by a thick, dark red mist. The surrounding air pressure suddenly dropped, creating a vacuum that sucked in the dust on the ground.
The real Moen Kang Yo had returned.
Han-Seung sensed the change. The hairs on the back of his neck stood on end.
"This aura... this is no longer just a management technique. This is pure demonic energy!"
"Elder,"
Kang Yo's voice now sounded hoarse and menacing.
"Let's see how many 'flower petals' you can maintain when the earth-shattering hammer strikes your garden."
Kang Yo moved. His steps were no longer measured to millimeter precision by Choin, but instead blasted with the thrust of a jet engine.
"Technique 1: Earth-Splitting Demon Strike!"
The massive Black Iron Heavy Sword was raised high. To an ordinary person, it would have been nothing more than a swing of a heavy sword. However, Han-Seung saw a different kind of horror. Thanks to Choin's "renovation" of the meridians, Kang Yo is able to concentrate the mass of his sword and Qi into one absolute vector point.
DUAAAARRRR!
The strike did not hit Han-Seung directly because the Elder managed to dart to the side using the 'Petal Drift' technique.
However, the shockwave from the black sword tore into the ground a meter deep. The cracks spread like lightning, destroying the stone foundation beneath Han-Seung's feet.
"Force distribution is successful, Boss!"
Choin's voice echoed in Kang Yo's mind.
"But watch the left wing. He is manipulating the air!"
Han-Seung did not stay still. As a Mastery level, he spun his thin sword, manipulating the airflow around Kang Yo into thousands of sharp wind blades.
"Plum Blossom Storm: Thousand Razor Petals!"
Kang Yo did not dodge. Instead, he lowered his center of gravity.
"Boss! Lock the shoulder and waist joints!"
Kang Yo commanded his other self.
"That's because you built your attack on empty air, Elder,"
Kang Yo replied, calmly stepping forward amidst the windstorm.
"As for me... I stand on this foundation you call 'garbage'."
Kang Yo spun his greatsword horizontally.
"Technique 2: Eternal Night Storm Sweep!"
The sword's rotation created such a powerful centrifugal force that it sucked in Han-Seung's plum blossom storm. All the energy Han-Seung had expended actually became an additional burden on Kang Yo's sword, increasing the momentum of the blow.
"Attack sector locked! Strike the energy pillar joint at his right wrist!" Choin shouted from within.
Kang Yo grinned. He adjusted the angle of his sword slash just three degrees downward, following Choin's technical instructions.
CRASH!
The black sword didn't cut Han-Seung's thin sword, but instead struck him with a mass equivalent to a ten-story building falling. The legendary Mount Hua thin sword bent so much that it broke.
"Ugh!" Han-Seung was thrown ten meters away, his hands trembling violently from the recoil that damaged his meridians.
At this point, Moen Kang Yo's true killing intent began to overflow. His eyes turned completely red, and he began to laugh in a terrifying tone. The black aura around him began to morph into wild energy tentacles.
"Die... you all must die... just like those who poisoned my mother!"
Kang Yo roared. He prepared to unleash the God Demonic Sword Art, a forbidden technique that could destroy his own body if not controlled.
"Warning! Overload! PSI pressure exceeds safe limits!"
Choin immediately took action. He flooded Kang Yo's mind with cold, logical blueprint images.
"Kang Yo! Look at your students behind you! Jin-Pyo is watching you! If you explode here, the entire Evernight Gate project will collapse!"
Hearing Jin-Pyo's name and catching a glimpse of the gate structure he was struggling with, Kang Yo gasped. His previously turbulent energy flow slowly returned to laminar flow under Choin's control.
"Thank you, Foreman... I almost destroyed our own property,"
Kang Yo whispered, his breathing steady.
Han-Seung struggled to his feet, his face now filled with pure fear. He realized he wasn't fighting a single warrior, but a dual entity possessing the destructive power of a demon and the precision of a creator.
"Who... who are you, really?"
Han-Seung asked, his voice trembling.
Kang Yo raised his Black Iron Heavy Sword, pointing it directly at the Elder's face.
"My name is Moen Kang Yo. The future leader of Evernight Gate,"
he declared with undeniable authority.
"And today, Elder Han-Seung, your field audit is declared a complete failure. Because you have disturbed the peace of my work area, the price is... your life."
Kang Yo lunged for the final blow. No longer with wild fury, but with a perfect synchronization of demonic speed and the foreman's logic.
The pace of battle slowed as the black sword moved in an unavoidable vertical trajectory, absorbing all the light around it, ready to utterly demolish the last symbol of Mount Hua's pride in the area.
