‘They recognized the Green Veil’s intensity and prioritized survival and concealment over an immediate offensive push.’

  Just as he registered the intelligent behavior of creatures, Keon’s attention was violently shifted by a flickering, massive shadow emerging from the central aperture of the portal.

  Three enormous, boxy shapes… The silhouettes began to emerge from the portal threshold. The sheer scale of the objects, dark and heavily armored against the swirling red-gold light, was an unexpected anomaly in their low-tier technology profile.

  ‘Tank, three units? Or some kind of armored transport?’

  Keon calculated his processors instantly, cross-referencing the size and mass with known military specifications in his memory.

  ‘It seems Kai has arrived. His immediate physical presence here explains the sudden intelligent behavior of the invading creatures.’

  Keon’s lens is fixed on the lead tank, linking the change of behavior with the arrival of these vehicles… He observed as they rolled inexorably toward the first defensive layer.

  ‘I wonder what will be the effect of my multi-filter layers on these tanks?’

  An intriguing surge of mechanical curiosity… A phenomenon akin to profound interest… ran through his core.

  The tank, covered in a repulsive, writhing layer of small, black biological matter, slammed into the Yellow Veil.

  The effect was immediate and dramatic. The low-intensity yellow plasma instantly incinerated the entire outer layer of worms and insects covering the tanks’ armor. Smoke and biological vapor erupted, a soundless scream of decomposing life, stripping the armor plating clean in milliseconds. The desert air immediately filled with a sharp, acrid scent, the chemical signature of superheated carbon and vaporized protein.

  Inside the command tank, the temperature spiked violently.

  A collective, startled cold breath escaped Lilith and the other subordinates. The sudden, intimate incineration of their protective shield, the momentary flash of yellow light, and the terrifying knowledge that their biological armor had instantly failed froze them.

  The cabin's air cooling system immediately began to whir in protest, pumping out stale, superheated air. The stench of burned organic matter, clinging to the hull, was instantly drawn into the ventilation system, making the air acrid and metallic. Lilith felt a wave of nausea, quickly masked by adrenaline, as the metal beneath her hand grew painfully warm.

  "Cover us! Undead, cover the tanks!" Kai’s voice, a whip-crack of absolute authority, instantly sliced through the shock. His eyes, fixed on the shimmering yellow wall, narrowed with ferocity. "Lilith! Open fire! Shoot the emitters! Neutralize that curtain!"

  CLANG!

  With a loud, metallic collision sound, the main cannon of the lead tank roared, spitting a high-velocity, shaped projectile toward the emitter's array in the filter. The shell left a brief, hot trail of fire in the 2.8 G atmosphere before impact.

  The shell struck the lattice of the plasma generator. The impact was significant, generating a localized flash of white-hot energy and a conclusive shockwave. The debris scattered around because of heavy gravity.

  Keon observed the result with a playful demeanor, a faint, non-audible mechanical hum of disdain resonating in his core. ‘These idiots, they used projectiles despite confirming the changes in gravity just now… looks like Kai destroyed all the intelligent creatures in the apocalypse, leaving behind useless vessels.’

  A few superficial scratches, no deeper than a few centimeters, appeared on the surface of the Adaptive Unified Composite Alloy (AUCA) frame supporting the emitters. The plasma emitters didn't even flicker. The Yellow Veil remained undisturbed.

  This tale has been unlawfully lifted from Royal Road; report any instances of this story if found elsewhere.

  According to Keon’s observation, the entire engagement… from projectile launch to impact… lasted 1.2 seconds, a testament to the useless efficiency of opponent weapon technology.

  ‘A Tier 3 alloy can't be easily damaged with a mere Tier 1 tank projectile,’ Keon thought, his mechanical assessment calm and dismissive. He is utterly disappointed with enemy intelligence and childish tactics.

  Before Kai’s team could fire a second shot, the lead tank, followed instantly by the other two, plowed through the Yellow Veil and into the intermediate space, rolling immediately toward the Green Veil. The heavy vehicles ground over the sand, their treads now slick with the fused residue of their bio-armor, the low rumble of their engines feeling deafeningly loud. A thin, whining shriek of protest rose from the tank's stressed axles as the 2.8G gravity pressed down on the massive chassis.

  The second layer… the high-intensity Green Plasma was a different filter entirely. It did not merely incinerate the surface matter; it radiated a corrosive, high-energy field. Any remaining, clinging bio-matter or larger worms that had managed to survive the first filter were instantly vaporized in a clean, green-white flash of light, leaving the tank hulls perfectly sterile but rapidly accumulating thermal stress.

  Inside the lead tank, the air pressure surged again. A technician cried out as a console sparked, the sheer thermal radiation beginning to fry the less-protected external systems. The smell of burning insulation joined the bio-matter stench.

  As the first tank rolled to the final meter, approaching the Blue Veil, the ultimate defense, the faces of the team inside shifted from shock to stark, terrifying realization. The previous two-layer defenses had stripped them bare. No undead creatures could possibly cover the tank in this place; the very air was a hot, sterilizing weapon.

  A thick layer of highly condensed carbon residue… the dark ash of their former shield… began to bake and condense on the superheated tank surface. The temperature inside the command tank rose at an alarming, exponential rate, straining the vehicle’s internal cooling systems. The air grew acrid, and the metal walls hummed with dangerous heat. Lilith’s eyes, catching Kai’s in the console glow, were wide with a terror she hadn't shown in the worst days of the Apocalypse. This was not a fight; it was a sterilization process.

  Even Kai’s expression, previously a mask of cold resolve, twisted into a look of ferocious, desperate anger. The heat was a physical violation, a sensation he hadn't felt in months, and it was coupled with the terrifying realization that his absolute control was worthless here. He understood the meaning of the next Blue Veil; it will be total annihilation for them.

  He did not hesitate. His black eyes darted down for a split second, fixing on the armored access hatch set into the floor of the tank's lower section… the emergency escape route.

  "Abandon vehicles! Now!" Kai bellowed, the order cutting through the roaring heat and the whine of the metal. "Down! Through the hatch, into the sand!"

  The command was absolute. Lilith and the remaining subordinates, despite their terror, moved instantly. They were trained to obey the impossible. They threw open the lower hatch while the tank was still in motion, its heavy tracks churning over the sand a meter away from the Blue Veil.

  The three command tanks, following their leader’s internal directive, executed a final, desperate surge of acceleration. They plowed straight into the Blue Veil, the high-intensity plasma instantly striking the now-exposed, superheated hull.

  …

  On the other side, in front of the base display,

  Keon, still within his Exoshell 3.0, watched the annihilation of three military tanks. The Blue Veil erupted in a violent, dazzling flash. Its destructive prowess exceeded his estimate by a large margin.

  ‘So this is the effect of Tier 3 plasma; it's totally an interstellar-grade weapon.’ Keon calculated as he observed the tanks transformed into deformed objects.

  The armored chassis, built from military-grade steel, did not stand a chance against the Tier 3 emitters. The hull of the three tanks buckled and warped, the steel plating sagging like wax. Within milliseconds, the boxy shapes collapsed into grotesque, molten puddles of unrecognizable, smoking slag, fused chunks of metal, and internal componentry. The vehicles were not destroyed; they were utterly unmade, their structure liquidated into formless scrap.

  Keon registered the scene… Three pools of violently cooling, deformed alloy emerged on the other side of the blue layer and halted precisely.

  ‘Structural integrity of their material reached 0%. Thermal destruction confirmed. All internal organic lifeforms should have been instantly vaporized by the hull’s conductive heat.’ Keon processed the conclusion, an iron certainty.

  Yet, a cold spike of doubt instantly pierced his mechanical logic. The internal chronometer registered a lag of 0.05 seconds, a fractional delay that should not occur in his core system. He cross-referenced the tank destruction with his core objective: neutralizing Kai.

  ‘No death signature detected for Candidate 546876 (Kai). No biological matter of that size registered by the scanners. Also, I didn't receive any notification from the system… Is it a delay, or did he survive somehow?’

  …
