52: Chapter 52. Tyranitar thought he could devour everything, until their devourers were chewed up like snacks by the swarm.

After the command neural layer of the Tyranid vanguard tendril was destroyed by the Titan-Eater, the remaining Spore Cysts in the void drifted aimlessly without coordination, most being cleared by the Blackstone Defense Line's spore minefields and the Imperial lance arrays. Marcus Aurelian stood on the bridge of the Wrath of the Emperor, the bone fracture in his right arm numbed by the pain of consecutive days of combat. He had just ordered the Third Assault Fleet to retract into an anti-air formation when over a dozen new alarms suddenly popped up on the Tech-Officer's console. These were not Spore Cysts or Cyst Ships; they were a wave of biological signals—smaller, faster, and denser than drop pods—penetrating at high speed from behind the wreckage of the Tyranid vanguard into the edge of the Blackstone Defense Line's identification zone.

"Genestealers." Nephilak's quantum-state communication patched into the bridge just as the alarms sounded. The Necron Overlord's voice remained steady, yet every word was as sharp as a blade. "The oldest infiltration units of the Tyranid Hive Mind. These devourers inject Tyranid genetic sequences the moment they contact target biomass, remodeling all host cells into Tyranid symbiotic tissue. The Necron Dynasty encountered an early version of these units during the last War in Heaven; back then, thirty Dynasty worlds had all surface organic matter infiltrated and devoured by their own kind without warning. The Hive Mind releasing this batch now indicates it has completed the reverse engineering of the Blackstone Defense Line's resonance frequency."

Marcus slammed a hand down on the fleet channel, ordering the entire fleet to concentrate all point-defense fire on the Genestealer clusters at the defensive line's perimeter, forbidding even one from passing through the spore mine dispersal zone into the Imperial Fleet's anti-air screen. Simultaneously, he sent an unprecedented request to the Brood Queen—to switch the Blackstone Defense Line's resonance frequency from fire-control guidance mode to bio-scanning mode to locate the infiltration paths of all Genestealers.

The Brood Queen's reply projected before him in less than a breath. The content: Most devourers have been intercepted at the perimeter, but a small group bypassed the active detonation range of the spore mines by overloading their own bio-electric fields and is approaching the Imperial Fleet's left-wing sector; coordinates marked. Marcus watched the cluster of Genestealers racing at high speed along the edge of the left wing's Void Shields and squeezed a single word from his throat: "Fire."

The Strike Cruisers on the Imperial Fleet's left wing opened their Lance Weapons to maximum scatter mode, forming a searing defensive ring of orange-red high-energy photon walls outside the Void Shields. Most devourers were incinerated instantly upon contact, but a few slipped through the charging gaps of the lances, slamming directly into the cruisers' bow armor. A captain roared over the comms channel: "They're eating the plasteel—they bypassed the Void Shields entirely and are burrowing directly into the armor plating!"

Sebastian's Thunderhawk Gunship dove from low orbit, and the Terminators squad jumped onto the hull of the cruiser infested by the Genestealers before the gunship had even fully stabilized. Sebastian stepped onto the writhing Tyranid symbiotic tissue, plunging his Power Sword into the dorsal carapace gap of a Genestealer burrowing deep into the armor plating; the disruption field blasted it into two halves. However, more Genestealers were swarming from behind, and one had already bored through the second layer of the cruiser's bow deck, its tendrils beginning to release Tyranid gene-modifying spores.

Just as Sebastian was about to order the entire deck floor blown, the Brood Queen's quantum translator broadcasted a brief message across all channels: "Do not detonate deck. Fall back." Four Drones flew from the Brood Lord's launch pods, landing directly on the armor plates breached by the Genestealers. They were only half the size of a Zergling, with no visible bone blades or spore vents on their carapaces, possessing only a set of genetic-devouring counter-templates urgently modified by the Overmind—an old trick the Zerg Swarm used against Xel'naga genetic weapons in the Koprulu Sector, retrieved and recompiled by the Brood Queen from the depths of the Overmind's genetic memory banks.

Dozens of ultra-fine Mycelial Probes extended from the Drones' appendages, piercing the expanding symbiotic tissue of the Genestealers. What they injected was not toxin or digestive fluid, but the Zerg Swarm's own genetic-devouring sequence—a targeted sequence recompiled through the Blackstone resonance chambers. The Tyranid Genestealers' modification speed was incredibly fast, capable of converting all host cells in a short time, but The Swarm's genetic-devouring sequence was faster; it didn't need to convert host cells, it directly ate the invader's genes.

Sebastian crouched on the armor plate, witnessing firsthand as the Genestealer that had burrowed deep into the cruiser's deck was back-injected with the genetic sequence by the Drone's Mycelial Probes. The Tyranid symbiotic tissue convulsed violently the moment it touched the Zerg genetic sequence; the dark purple tendrils lost their color in seconds, turning from purple to gray, then gray to white, and finally being completely decomposed and absorbed by the Drone's appendages. All that remained was a pile of carbonized protein residue that even the Tyranid Hive Mind could not reclaim. The Drones packaged the absorbed Tyranid genetic information and sent it back to the Hive Mind. Seconds later, the genetic analysis sacs reached a full conclusion: the Tyranid genetic-devouring sequence could be reverse-compiled by The Swarm, and the devourers themselves were no longer a threat.

Marcus stared at the real-time footage sent back by the Tech-Officer for a moment of silence, then ordered the comms channel to archive those Drones along with their genetic counter-templates, announcing to the entire fleet: "Fear the Tyranid devourers no longer—The Swarm can devour them right back." He then sent a short message of gratitude to the Brood Queen: "Thank you." This xenos ally had just sent Drones to save an Imperial cruiser.

The Brood Queen did not respond to his thanks. She was busy translating all the Tyranid genetic-devouring sequences recovered by the Drones into The Swarm's own genetic-devouring modules. The Overmind reviewed the complete data within the Hive Mind, confirming The Swarm's immunity to Tyranid genetic infiltration, and wrote this conclusion into all Brood Queen nodes. In orbit of Graia, a new batch of newly-hatched Drones completed their genetic-devouring counter-template updates while still in the embryonic stage. All engines of the Blackstone Defense Line maintained full anti-psionic suppression, keeping the main Tyranid fleet blocked at the perimeter. The Titan-Eater continued clearing the remaining Cyst Ship formations within the vanguard wreckage. The Overmind assigned the next strategic adjustments to the Brood Queen, preparing to use the Tyranid Hive Fleet as a sample group for the next round of large-scale genetic devouring. Deep within Talastra, the Blackstone Cerebrate recalibrated the Void Gate's energy circuits, patching the reverse-decoded Tyranid command neural layer data into the blackstone network's quantum resonance main console for future use.

Marcus stood tall on the bridge, slowly tightening a loose strap near his shoulder guard with his left hand. He issued a fleet-wide command: "Notify all units. If Genestealers are encountered on the battlefield from now on, ships no longer need to perform evasive maneuvers or self-destruction protocols. The Swarm will take over all Tyranid genetic counter-missions. Our temporary allies no longer view the Tyranids as a threat—they are treating the Tyranids like a buffet."
