The dawn sky over the Black Dragon Mountains was still a deep purple-blue as Moen Kang Yo's small group crossed the main gate of Evernight Gate. The thin mountain air was sharp, piercing the lungs with a chill.
However, inside the sect grounds, the chill was quickly dispelled by the heat emanating from the blacksmith's workshop. The pounding of hammers striking hot iron was rhythmic, like the heartbeat of a sect that had just awakened from its dormant state.
Yoe Choin paused in front of the workshop, watching the sparks leap from the anvil. His eyes, glowing blue like Blueprint, immediately scanned the quality of that morning's forging.
"Gwi-Hyuk,"
Choin called out in a low, authoritative voice.
"Make sure the blacksmiths don't cut corners. These steel nails must have the right carbon content. If they're too hard, they'll become brittle and break under shear loads. If they're too soft, they'll bend. I need absolute structural balance."
Gwi-Hyuk nodded silently, his sharp eyes observing the workers, who now seemed much more diligent, both out of fear and respect for their 'Demon Overseer.'
Choin stepped into the Main Pavilion, where Baek-Un was waiting for him with a large table covered with topographic maps and technical sketches Choin had drawn himself earlier. The pungent aroma of alcohol from Baek-Un's bottle mingled with the smell of fresh ink and wood dust.
"Overseer, you're back sooner than I expected,"
Baek-Un said as he took a sip, but his sharp eyes immediately fell on the plum blossom metal piece Choin had placed on the table.
"So, those Mount Hua rats have begun to dare to cross the border bridge?"
Choin pulled out a sturdy teak chair and sat across from the strategist.
"They only sent a 'junior inspector' to bluff, Baek-Un. But the vibrations on the bridge prove one thing: they feel threatened by our audit."
Choin pointed to an area on the map of the sect's front gate.
"Forget diplomacy. We'll begin the Physical Renovation phase now. I want you to translate the principles of the 'K3 SOP' into a static defense formation."
"Look at this,"
Choin continued, drawing a line on the map.
"We'll turn the main entrance into a deadly maze. We won't use conventional traps that rely on crude mechanical sensors. We'll use Frequency Distribution. Install Black Iron bells underground at the pillars' load-bearing points. When enemies step with heavy Qi, the vibrations of their footsteps will trigger a sonic resonance that disrupts the balance of their Dantian."
Baek-Un paused, his rough fingers stroking his scruffy beard.
"Crazy... you want to turn this entire building structure into one giant weapon? Without even a single disciple needing to swing a sword, the enemy will experience disruptions in energy flow just by walking on our floor?"
"Exactly,"
Choin replied coldly.
"That's efficient management. Why waste human labor when the building's structure can do the work for you?"
Baek-Un laughed wildly, a fire of strategic passion reigniting in his long-dimmed eyes.
"Chief Engineer... you truly treat war like a construction project that must be completed on time. I will begin preparing the instructional curriculum for the students tomorrow morning."
Midway through the conversation, the door to the office opened slowly. Han So-Wol entered with a determined stride, carrying her large abacus and a stack of rolled-up financial reports, now much tidier than when Elder Gong was in power.
"Foreman, I have completed the audit of the assets confiscated from Elder Gong's residence,"
So-Wol reported matter-of-factly. Although her voice remained stiff, there was a tinge of confidence she had never seen before.
"We have a 40% surplus after allocating for initial infrastructure improvements and student nutrition."
Choin looked at So-Wol, giving a rare, faint smile.
"Good work, So-Wol. Make sure our cash flow stays clear. Don't let a single piece of silver flow down the drain. Remember, every lost piece of gold is a loose nut in our defenses."
So-Wol glanced at Choin for a moment, her face flushing slightly, but she quickly hid it behind her stack of documents.
"I've also prepared a budget for the 'Demolition Unit.' Fresh meat and muscle-recovery herbs will arrive this afternoon. I don't want any 'pillars' cracking from malnutrition."
The sun was beginning to rise higher, illuminating the now-clear training field. Instructor Ma was already standing in the center of the field, supervising the Year 1 and 2 students who were performing static postures under the measured weight of rocks.
"Straight back! Don't let your shoulders hunch like rotten wood!"
Ma shouted, his voice booming like a disciplined drill sergeant.
Choin stepped into the special fenced-off area for the Demolition Unit. There, Jin-Pyo and seven other selected students were grappling with loads far heavier than those of ordinary students. Jin-Pyo, with his massive frame, was carrying a block of Black Iron weighing hundreds of kilograms while walking with a steady stride.
"Stop!"
Choin ordered.
Jin-Pyo put down his load with a thump that shook the ground.
"Young Master! Excuse me, I felt my knee joint shake a little on the third step,"
Jin-Pyo said honestly, beginning to learn the technical terminology of his foreman.
"That's because your weight distribution is too forward, Jin-Pyo,"
Choin approached and adjusted Jin-Pyo's foot position with the tip of his own foot.
"In the Demonic Heavy Sword technique, you don't just swing a metal bar. You are the fulcrum of gravity. Use your body mass as backup momentum. When you strike your opponent, imagine you are a pile driver dropping a ten-ton weight from an absolute height."
Chōin took his own heavy sword and demonstrated a simple swing, yet one that contained incredible mass.
WHUSH!
The wave of air pressure from the sword swing extinguished the still-lit torches on the sidelines. The Demolition Unit students held their breath, feeling the incredible density of Qi from this seemingly efficient movement.
"Jin-Pyo, you are the foreman on this field,"
Chōin said, patting his favorite student on the shoulder. "Make sure your comrades don't rely solely on muscle power. Use structural logic. If your opponent attacks from above, don't support their weight vertically. Divert their force to the ground through the angle of your feet. Make the earth the foundation of your defense."
Jin-Pyo bowed deeply, his eyes gleaming with the unwavering spirit of the "Model Coolie."
"Ready, Foreman! We will be a concrete wall that can never be broken!"
That afternoon, when the sect had calmed down a bit, Choin stood on the balcony of his pavilion, gazing northward, where dark clouds were gathering over the Orthodox Faction's territory.
"Foreman... you're truly insane with that sonic bell tactic,"
The voice of the original Moen Kang Yo echoed within him, this time with a tone of genuine admiration.
"Before, I only thought about beheading everyone who came. But you... you want to drive them insane before they even see our faces."
"That's because you see the enemy as a target, Kang Yo,"
Choin replied quietly in his mind.
"Whereas I see them as variables to be managed. If I can defeat them logistically and psychologically through structural means, why should I soil my sword with cheap blood?"
"Heh... still, when that senior inspector from Mount Hua comes, let me take over the motor skills,"
the real Kang Yo hissed in a bloodthirsty tone.
"I want to experience what it's like to crush their plum swords with this heavy technique of yours."
"We'll see, Boss Demon,"
Choin grinned faintly.
"But one thing's for sure... this field audit has just entered its bloodiest execution phase. Anyone who tries to tear down our house will be buried alive within the foundations I personally built."
The night wind began to blow harder, carrying the scent of iron and sweat, a sign that the renovated Evernight Gate had transformed into a defensive fortress ready to shake the entire Jianghu order.
