The secure communication line to Siberia crackled with static. Mikhail leaned closer to the monitor, his sister's face pixelated but recognizable on the screen. Behind her, laboratory equipment and snow-covered windows painted a picture of isolation and safety that Bangkok no longer possessed.
"Misha," Katya's voice came through distorted. "The connection isn't secure. We have two minutes before they might intercept."
"They?" Mikhail questioned. "The infected?"
"Yes," she confirmed, her eyes darting to someone off-screen. "They're accessing communication networks somehow. We've detected attempts to breach our systems from infected zones. They're... coordinated."
Mikhail nodded, unsurprised after what he'd witnessed. "I need the resonance frequency you were working on before I left Moscow. The inhibitory one that disrupted neural pathogen transmission in the early trials."
Katya's expression shifted to one of concern. "Those frequencies only worked temporarily. The fungus adapted within hours."
"I don't need a permanent solution right now," Mikhail explained urgently. "Just something to disrupt their coordination long enough for us to evacuate. We're surrounded."
Another explosion rocked the building, closer than before. Dust rained from the ceiling tiles.
"Transferring data now," Katya said, typing rapidly. "But Misha, there's something else you need to know. We've identified a pattern in the infections. They're targeting specific individuals first—scientists, communications experts, military personnel."
"They're after strategic knowledge," Mikhail realized.
"Exactly. And they're leaving certain people untouched. We've confirmed multiple cases of individuals with natural immunity."
Mikhail's screen pinged with an incoming file transfer. "The frequencies?"
"Yes, and something else. A genetic marker we've isolated in the immune individuals. Their cells produce a unique enzyme that breaks down the fungal connection to neural tissue." Her voice lowered. "Misha, if you encounter any immune individuals, their blood could be the key to a treatment. Perhaps even a cure."
The screen flickered as another explosion shook the building.
"Connection destabilizing," a computerized voice announced.
"Katya, what's the status in Russia?" Mikhail asked quickly.
"Moscow fell three days ago. The northern regions are holding. The cold is—" The screen went black.
Mikhail stared at the dead monitor for a moment before Agent Chen's voice pulled him back to reality.
"Dr. Volkov, we need to move. Now."
Gathering the data Katya had sent, Mikhail followed Chen back to the lab where Dr. Harrington and Areeya were hastily packing critical samples.
"I have potential disruption frequencies," Mikhail announced, handing the data to Areeya. "And information about natural immunity. Apparently, some individuals produce an enzyme that prevents neural integration."
Dr. Harrington's eyes widened. "That could explain the reports we've been getting about untouched civilians in infected zones. We assumed they were just lucky."
"Not luck. Biology." Mikhail helped Areeya load samples into portable containment units. "If we can synthesize this enzyme—"
"First we need to survive," Chen interrupted, checking his weapon. "The evacuation helicopter is on the roof. We have less than five minutes."
Areeya looked up from the frequency data. "I can configure the building's emergency broadcast system to emit these disruption waves. It might buy us time."
"Do it," Harrington ordered. "Everyone else, grab what you can and head for the roof."
As Areeya worked at the control panel, Mikhail packed the last of his research materials. Through the laboratory windows, he could see the courtyard below where dozens of infected moved with disturbing synchronicity. Some carried weapons, others communication equipment. Among them walked what appeared to be recently turned victims, their transformations incomplete—fungal growths just beginning to emerge from their skin and orifices.
"They're not attacking each other," Mikhail observed. "The newly infected and the fully transformed are cooperating."
"Hierarchical organization," Harrington said, joining him at the window. "Like a colony. We've observed different... castes developing among the infected. Some appear to serve specialized functions."
Before Mikhail could respond, a high-pitched sound began emanating from the building's speaker system. Though barely within human hearing range, its effect on the infected below was immediate and dramatic. They clutched at their heads, movements becoming erratic and uncoordinated.
"It's working!" Areeya exclaimed. "The frequency is disrupting their network!"
"Let's move," Chen ordered, leading them toward the emergency stairwell.
As they rushed upward toward the roof, Mikhail's mind raced. The fungal network, the coordinated behavior, the selective targeting—it all suggested not just a parasitic infection but an emergent intelligence. Something using human hosts to achieve specific goals.
They burst onto the rooftop helipad where a military helicopter waited, rotors already spinning. The American general stood at the door, urgently waving them forward.
"Hurry!" he shouted over the rotor noise. "We've got multiple breaches in the building!"
As they ran toward the helicopter, a door on the far side of the roof crashed open. A group of infected poured through, led by a figure that made Mikhail's blood run cold.
It had once been human—a man in what remained of a business suit—but fungal growths had transformed it into something else. Fruiting bodies erupted from its shoulders and back, creating a grotesque crown-like structure. Its eyes were gone, replaced by fleshy fungal pads, yet it moved with purpose, turning its head directly toward Mikhail.
"Priority target identified," it said in a distorted but clearly intelligible voice. "The epidemiologist."
The infected behind it raised improvised weapons and what appeared to be actual firearms.
"Run!" Chen pushed Mikhail forward as he turned to fire at the approaching infected.
The disruption frequency still blared through the building's speakers, but the crowned infected seemed less affected than the others, its movements more deliberate.
"They're adapting already," Harrington gasped as they reached the helicopter. "The frequency won't work for long."
The general pulled Harrington aboard while Mikhail turned back for Areeya and Chen. The agent was firing controlled bursts, dropping infected with headshots, but they kept coming. Areeya stumbled, clutching the case of samples to her chest.
Mikhail ran back to help her, reaching her just as Chen's weapon clicked empty.
"Go!" Chen shouted, drawing a sidearm. "I'll hold them!"
The crowned infected raised its arm, and to Mikhail's horror, the other infected immediately changed formation, spreading out to flank Chen.
Helping Areeya to the helicopter, Mikhail watched as Chen fired his last rounds. The agent managed to drop several infected before the crowned one made a quick gesture. Three infected rushed forward simultaneously from different angles, overwhelming Chen in seconds.
"We have to leave now!" the pilot shouted as Mikhail and Areeya climbed aboard.
"Wait!" Mikhail yelled, watching in horror as the crowned infected bent over Chen's struggling form. Something like a proboscis extended from its mouth, plunging into Chen's neck. Chen's struggles weakened immediately.
The helicopter lifted off as more infected poured onto the roof. The last thing Mikhail saw was the crowned infected looking up directly at him, Chen's now-still body at its feet.
"What was that thing?" Areeya asked, voice shaking as Bangkok fell away beneath them.
"A specialized form," Harrington answered grimly. "We've been calling them Alphas. They appear to function as command nodes in the network." She turned to the general. "That's the closest one has ever gotten to capture. It specifically identified Dr. Volkov."
"They're targeting key personnel," Mikhail confirmed, remembering Katya's warning. "Scientists, especially those with knowledge about the fungus."
"Which means they understand who poses a threat to them," the general concluded. "This isn't mindless spreading. They have objectives."
As the helicopter banked east, Mikhail could see plumes of smoke rising from across Bangkok. The infection was spreading rapidly through the densely populated city. On major roadways, streams of vehicles attempted to flee, creating massive traffic jams that would only accelerate transmission.
"Where are we going?" Mikhail asked.
"U.S. Seventh Fleet," the general replied. "We have a carrier group in the Gulf of Thailand. It's been converted to a floating research facility. Best containment systems available."
Mikhail thought of Chen, of the way the crowned infected—the Alpha—had looked directly at him. There had been intelligence in that gaze. Purpose.
"I need to send a warning to Siberia," he said. "The disruption frequency won't work for long. The network is adapting too quickly."
"Communications from the carrier," the general promised. "For now, review what your sister sent. If there are naturally immune individuals out there, we need to find them."
Mikhail nodded, opening his laptop. The data Katya had transferred included not just frequency information but genetic sequencing of the enzyme produced by immune individuals. The enzyme appeared to target the unique mechanisms the fungus used to interface with human neural tissue.
"Dr. Surin," he called to Areeya, who was still visibly shaken from their escape. "I need your expertise with this enzyme structure."
The young scientist moved closer, grateful for the distraction from their narrow escape. Together they began analyzing the molecular structure displayed on Mikhail's screen.
"This is fascinating," Areeya said after several minutes. "The enzyme targets the fungal signaling pathways without affecting human neurotransmission. If we could synthesize this..."
"We'd have a treatment, not just a temporary disruption," Mikhail finished. "But we'd need blood samples from immune individuals to produce it at scale."
From across the helicopter, Dr. Harrington spoke up. "We've had reports of untouched individuals in infected zones across multiple continents. If this immunity marker is consistent, we could potentially identify carriers through genetic screening."
"And make them targets," the general added darkly. "If the network is specifically hunting threats, individuals with natural immunity would be high on their list."
The helicopter communication system crackled to life. "Approaching USS Gerald R. Ford. Prepare for landing."
As they began their descent toward the massive aircraft carrier visible in the distance, Mikhail gazed back at the Thai coastline. Fires burned across Bangkok's skyline, and even from this distance, he could see the chaos spreading through the city.
"We need to find these immune individuals before the network does," Mikhail said, determination hardening his voice. "And we need to understand what the infected are building toward."
"What do you mean, 'building toward'?" the general asked.
"This level of coordination, the specialized forms, the targeted hunting—it all suggests a larger purpose," Mikhail explained. "They're not just spreading randomly. They're creating infrastructure. The question is: for what?"
As the helicopter touched down on the carrier deck, Mikhail caught sight of dozens of other aircraft—military and civilian—landing and taking off. The massive ship had become a floating fortress in the growing chaos, one of the few safe havens in a rapidly collapsing world.
But for how long? The crowned infected—the Alpha—had looked at him with such specific intent. The network knew who he was, knew his importance to potential countermeasures.
Which meant the network was afraid of what he might discover.
And that, Mikhail realized as they were escorted into the carrier's depths, gave him something he desperately needed:
Hope.
