I Copy the Authorities of the Four Calamities

Chapter 419: Reserve

By the fourth day, the coastal zone carried an entirely different atmosphere.

The threat population itself had certainly thinned, leaving their sector work running at a much lower, manageable register compared to the violent chaos of the first three days. But the real difference was inside the unit itself. Three days of lethal output with real, bleeding stakes had fundamentally burned away the rigid, performative layers of the Academy.

Nobody was standing with perfect, textbook posture to impress an invisible evaluator anymore. The desperate, exhausting fuel of "I am currently being graded" had completely evaporated. What remained was just the raw, brutal work, and the hardened people doing it.

Kael no longer looked like a terrified first-year student frantically managing his appearance. Covered in rock dust and dried monster blood, his movements were efficient and grounded. He looked like someone who actually belonged in a combat zone.

The morning brought a sudden, vicious ambush from the east. The monsters did not pour in from the standard approach vectors the official briefing had promised. They erupted from a narrow ridge gap that Fen had quietly flagged on day two as a secondary possibility. She had been absolutely right to flag it. The beasts’ behavioral logic was terrifyingly fast, driving a feral sprint straight toward the eastern boundary before anyone’s brain had fully processed the blur of motion.

Kael was holding the eastern anchor. He saw the blur arrive. He didn’t freeze, and he didn’t wait for an order.

He violently closed the line before Vane even finished reading the shift in the ambient field. The rookie’s defensive sweep was clean, brutal, and entirely instinctive. It was the specific kind of muscle memory that only solidified when four days of sheer terror finally settled deep below the level of conscious thought. Kael completely sealed the defensive gap before the threat could breach the boundary line. The beast went down in a single, wet crunch.

Kael lowered his weapon, breathing heavily. He looked directly at Vane.

"I saw the eastern line breaking and I closed it," Kael reported, his chest heaving. He didn’t flinch. "I should have called out the movement to the squad first."

Vane lowered his own spear. "Yes."

"I was going to make the kill in time."

"You were."

"But I called it after the fact," Kael noted grimly, perfectly recalling the harsh lesson Vane had dealt Aldric on their first night.

"Yes."

"I will call it first next time," Kael promised.

There was absolutely no defensive argument in his tone. He didn’t try to justify his silence by pointing out that the monster was dead anyway. He simply offered the tactical correction and owned the mistake.

"Good," Vane said softly.

Kael turned his back and resumed his watch over the tree line. Sitting nearby, Fen had been quietly observing the entire exchange. She didn’t say a word. She simply made a tiny, satisfied notation in her leather notebook and went right back to mapping the field.

Fen officially handed over her completed map at midday.

She ripped four dense pages completely out of her notebook. She had carefully aligned the torn edges to form a massive, continuous spread of the coastal sector. She set the sprawling document flat on the grey stone beside Vane without a single word of dramatic introduction.

Vane picked it up.

It was infinitely better than the Academy’s official briefing.

It wasn’t just a marginal improvement. The Academy’s document had been lazily stitched together from a nearly two-decade-old cartographic survey, blindly trusting theoretical projections rather than measuring the actual environment. What Fen had painstakingly built across four days of survival was a living, breathing blueprint.

Every single approach angle was rigorously tested against real field variance readings. Every feral behavioral pattern was meticulously logged with exact timestamps. She had drawn the terrain’s actual, jagged geometry rather than a smoothed-over approximation. The lethal eastern ridge was finally mapped at its true, steep slope. She had charted the hidden secondary approach channels, mapped the invisible ambient mana currents, and accurately highlighted the hidden corridors the monsters actually used to travel.

"This is exactly what tomorrow runs on," Fen told him, tapping the heavy parchment. "If you want to permanently close the eastern sector without burning more of our core reserves than absolutely necessary, the exact approach timing is listed on the third page."

Vane scanned the third page. The timing sequence was flawless. It factored in the shifting mana current cycles, with the optimal strike window circled in dark charcoal.

"The Academic Archive," Vane murmured, staring at the genius of it.

"I know," Fen replied, a faint, fierce light burning in her eyes. She had already decided she was submitting the corrected map to the highest governing body at Zenith. She just hadn’t dared to say it out loud until now. "I will file it the second we are back."

Aldric had been voluntarily sitting with Fen on the morning watch for three consecutive days.

By day four, there was absolutely nothing strained or performative about the dynamic between the high-born aristocrat and the low-ranking scout. Fen did most of the talking during those dark hours because the pitch-black shadows made it easier to verbally explain magical concepts that were too hard to visually show. Aldric sat silently and listened. Two days ago, he had firmly decided that Fen’s understanding of field variance was a completely different tier of magic, and he absorbed her words the exact same way he absorbed lessons from Vanguard masters.

She tested him on the elusive low-frequency mana pattern again during the afternoon watch. It was the specific, invisible current he had completely failed to find on their first night.

Aldric stared out into the rippling field for a very long time. His eyes narrowed.

"There," Aldric breathed, pointing a gloved finger. "It is running southwest."

Fen followed his hand. She checked his observation against her own raw readings.

"Yes," Fen smiled slightly. "It is actually running much earlier today than it did yesterday."

"I know. I have been actively hunting for it since this morning."

"I know," she said quietly. "I watched you."

Aldric turned his head to look at her. "How long have you actually been tracking that specific shift?"

"Since zero four hundred."

Aldric paused. He had been killing himself looking for it since zero six hundred. Fen possessed two full hours of baseline data that he completely lacked. He processed the humbling reality without a single flinch of aristocratic pride. He looked back out at the shimmering southwest variance.

"Show me the zero four hundred signature," Aldric requested humbly.

She picked up her pen and showed him.

Ashe slipped through the grid boundary in the mid-afternoon.

Her squad had thirty minutes of dead time before their next defensive hold rotation. Their two sectors overlapped just enough that those thirty minutes were entirely hers to use however she chose. She chose to use them sitting on a rock next to Vane.

She immediately leaned over and studied the sprawling map Fen had built, currently weighed down with stones on the ground. Ashe’s dark eyes zeroed in on the third page’s intricate approach timing.

"Tomorrow," Ashe noted.

"Yes."

"He is going to ask you for the command of the closing sequence," Ashe said, keeping her voice low.

"Aldric?"

"Yes." She looked down the ridge at Vane’s unit. Aldric was standing tall at the northern anchor. Fen was actively mapping a new variance position. Kael was holding the eastern edge like a stone statue. "I read your sector logs again. I can clearly see what that boy has been building toward for four straight days."

She turned her attention to Vane. "He ran toward the bloody assist on day two. He swallowed his pride and begged Fen to teach him the invisible field reads. He corrected himself after a unilateral call and didn’t offer a single arrogant excuse." Ashe looked back at the Peak Elite. "He has been meticulously assembling the right model of command. He should get the final engagement that perfectly fits it."

"I was already planning to give it to him," Vane admitted.

"Good." Ashe stood up to head back toward her own sector. She paused, looking back over her shoulder. "But he is going to argue for it. He is going to march up to you and formally make the tactical case for why he should lead the spearhead."

"I know."

"Let him," Ashe advised softly. "His case is going to be good. You can say yes because his tactical argument is flawless, not just because you had already made up your mind to give him a gift."

She offered a fleeting smile and vanished back along the spine of the ridge.

Day four closed with the massive eastern cluster perfectly contained by the mathematical predictions on the third page of Fen’s map. The charcoal circle marking the optimal strike window was exactly what Vane had been staring at since midday.

They had one more night. One more day.

Aldric was out on the perimeter watch. Fen was out there with him. They were talking in low, intense murmurs—the focused, professional conversation of two soldiers actively dismantling a problem together while the ambient field variance ran its wild patterns in the dark below.

Kael was fast asleep. The rookie had dropped into a deep, dreamless rest the absolute second his shift ended. He had finally learned to treat sleep as a vital tactical tool, utilizing it efficiently the moment it became available.

Vane sat alone near the dying campfire, running the final evening assessment on his glowing wristband. He reviewed the eastern cluster’s coordinates, the closing approach window, and finally, his own academic scoring log.

He was currently sitting in sixth place overall. The log contained a glowing, heavily asterisked notation regarding his exceptional command quality. Right beneath that was the staggering list of massive point deductions he had suffered for abandoning his post on day two. It was a complete, unapologetic record of what these five days had actually cost him, and exactly what his unit had produced in return.

Tomorrow, the bloody account would finally close.
