The concrete floor shook again. Dust fell into Lain’s eyes, making him blink. The iron door groaned as something heavy bumped against it from the outside tracks.
"They found us," Leo whispered, standing up and gripping his baton.
Mavis stepped back from the green-eyed tongue helper. "Lain, the sounds from the vents are getting louder. The big monster upstairs is searching the area."
Lain stood up and looked at his blue screen.
Current points: 20.
Current squad: Hook Mutant (Lv. 2), Tongue Mutant (Lv. 2).
Spiked Guard (Lv. 5) is holding the surface stairs.
"We cannot stay in this room," Lain said. "We will get trapped like rats. Follow me."
He unlocked the heavy iron door and pushed it open. The dark subway tunnel was full of low, scraping sounds. A group of ten regular zombies was shuffling toward them from the dark end of the tracks.
"Helper one, helper two, go!" Lain ordered.
The Hook Mutant and the Tongue Mutant rushed forward together. The Tongue Mutant shot its long, wet tongue out, wrapping it around a zombie’s neck and slamming it into the ground. The Hook Mutant followed up, slicing with its sharp bone fingers.
Lain and Leo moved along the wall, keeping Mavis between them. Lain kept his metal pipe ready, his eyes watching his point total grow.
Enemy defeated. +10 points.
Enemy defeated. +10 points.
"Lain, look ahead!" Leo yelled, pointing his flashlight.
A different kind of monster was blocking the exit gate at the end of the tunnel. It was trapped inside a metal cage meant for storage, but it was breaking the bars. It was covered in thick, jagged pieces of scrap metal that had melted directly into its skin.
The scrap-metal monster roared, its voice echoing loudly in the enclosed tunnel. It ripped a heavy iron bar off the cage and threw it like a spear. The bar missed Leo by an inch, embedding itself deep into the concrete wall.
"That thing is dangerous," Mavis said, her face pale. "Its skin has fused with iron. Normal weapons won't pierce it."
"Then we use the system," Lain said. "Helpers, attack!"
The Hook Mutant leaped at the scrap-metal monster, swinging its sharp claws. Clang. The bone hooks hit the metal skin and snapped off, green blood spraying from the helper’s fingers. The scrap-metal monster grabbed the Hook Mutant by the head and smashed it hard into the ground, crushing its skull.
Your Hook Mutant (Lv. 2) has died.
"Damn it," Lain muttered. He looked at his screen. The point total had reached forty from the smaller zombies.
The Tongue Mutant tried to bind the monster's arms, but the scrap-metal creature caught the tongue with its bare hands and pulled hard. It ripped the tongue right out, causing the helper to dissolve into gray dust.
Your Tongue Mutant (Lv. 2) has died.
"Lain, we have no helpers left!" Leo shouted, stepping in front of Mavis with his baton raised high.
The scrap-metal monster turned its white, angry eyes toward Lain. It took a heavy step forward, the concrete cracking under its iron feet.
Lain did not run. He opened the system store on his screen, his fingers moving fast.
Points available: 40.
Emergency Synthesis available. Cost: 40 points. You can merge nearby scrap metal with your system energy to create a new weapon or thrall.
"Do it!" Lain thought loudly.
A bright blue circle appeared on the floor right between Lain and the charging monster. The broken metal bars, the dropped iron pipes, and the scraps of metal from the destroyed vending machines all lifted into the air. They flew into the glowing circle, spinning fast like a silver vortex.
The scrap-metal monster ran straight into the light, trying to smash Lain.
Synthesis target captured. Merging scrap metal with organic virus base...
The spinning metal pieces slammed into the monster's body, wrapping around its arms and legs like heavy chains. The creature roared in anger, but it could not move. The blue light turned deep purple, sinking into the monster's skin.
The monster's white eyes flared, then turned a bright, solid green.
The purple light faded. The creature was completely changed. Its body was now covered in sleek, black steel armor that looked like a futuristic suit. Long, sharp blades grew out of its forearms, glinting in the dark tunnel.
Synthesis successful. New Unit created: Iron Blade Vanguard. Level 4.
"Wow," Leo gasped, lowering his baton. "That looks like a robot."
"It is not a robot," Mavis said, stepping closer to look at the sleek metal armor. "It is a perfect fusion of biology and technology. Look at the joints."
The Iron Blade Vanguard knelt on one knee in front of Lain, its head bowed low in total obedience.
"Stand up," Lain commanded.
The metal helper stood up instantly. It was taller than Lain, its sharp arm blades clicking together with a cold, metallic sound.
"We need to get to the surface now," Lain said, looking back down the tunnel. More growls were coming from the dark. "Iron Blade, clear the path."
The metal helper turned around and dashed into the dark tunnel. It moved incredibly fast, its blades cutting through the incoming wave of normal zombies like paper.
Lain, Leo, and Mavis ran right behind it. With every slice of the Iron Blade's weapons, Lain's screen flashed with green text.
Enemy defeated. +10 points.
Enemy defeated. +10 points.
Current points: 60.
They reached the exit stairs and ran upward, leaving the dark subway behind. The hot, red air of the surface hit their faces again.
Up on the street, the level-five Spiked Guard was still fighting, but it was covered in deep burns. It was surrounded by a massive horde of hundreds of zombies.
"Iron Blade, go help him!" Lain ordered.
The level-four metal helper jumped into the street, its arm blades spinning. It sliced three monsters in half with one swing, standing shoulder-to-shoulder with the Spiked Guard.
"We are still surrounded," Leo said, looking at the endless crowd of monsters running down the avenue. "Where do we go now?"
Lain looked at his screen. He had sixty points. He looked at his two powerful helpers holding the line.
"We don't run anymore," Lain said, his voice cold. "We clear this street."

Chapter 18: The Border Bridge
Lain tapped the golden evolution icon on his glowing screen while the truck raced down the wet highway. A bright green flash flooded the cabin as his system processed the thousand points."System evolving," Lain said, keeping his eyes on the road. "Void Sovereign is unlocking its ultimate form."Evolution complete, the system panel flashed. Void Sovereign reached Level 10. New Skill unlocked: Kinetic Singularity.Up ahead, the massive concrete pillars of the border bridge appeared through the heavy fog. Dozens of abandoned cars blocked the entrance, and a heavy corporate blockade sat right behind them."They've got heavy machine guns on those sandbags!" Leo shouted, leaning forward from the back seat. "They're aiming right at our front tires!"Lain didn't slow down, slamming his foot flat on the gas pedal. "Void Sovereign, clear the barricade!" he ordered through his mind link.The level-ten helper materialized fifty yards ahead of the truck, its six wings now burning with intense whi
Chapter 17: Outpost Siege
The heavy truck smashed through the rusty chain-link fence of the military outpost, coming to a sliding stop inside the main yard. Lain cut the engine, grabbed a shotgun from the rack, and kicked his door open."Leo, watch the high walls!" Lain shouted, stepping into the mud. "Mavis, grab the medical kit and stay behind me!"Two infected soldiers wearing torn camouflage gear sprinted out of the open guardhouse, their mouths dripping thick black slime. Lain raised the shotgun and fired twice, blasting both creatures off their feet into the dirt.Leo pulled himself out of the truck, using his rifle for support as he scanned the watchtowers. "The perimeter wire is down on the north side!" Leo shouted, pointing his barrel toward the dark wood line.A pack of eight mutated hounds burst from the trees, their skin peeled back and their glowing red eyes locked on Mavis. "Mavis, back into the truck now!" Lain yelled, tapping his glowing system screen."Obsidian Behemoth, deploy and crush them!
Chapter 16: Counter Strike
"Fire!" the commander screamed, pulling his trigger first. A wave of blue plasma bolts rained down on Lain, tearing through the rain and light.The Obsidian Behemoth lunged in front of Lain, raising its massive arms to form a solid wall. The plasma shots slammed into its dark chest, leaving glowing red marks but failing to break through."Void Sovereign, take out the commander!" Lain shouted. The six-winged helper disappeared from the asphalt, leaving behind a sharp crack of displaced air.It reappeared behind the commander and drove its energy blade straight through his heavy chest armor. The commander dropped his plasma rifle and fell dead onto the wet highway."Supplies coming from the right!" Mavis yelled, leaning out the truck window to point her flashlight. A second squad of soldiers moved around the side of the truck, raising heavy grenade launchers.Leo leaned out from the passenger seat and fired three quick rifle shots into the lead guard's helmet. The guard stumbled backwar
Chapter 15: Highway Breach
The mounted turrets roared as heavy bullets tore through the front rank of the incoming horde. The armored truck plowed straight into the crowd, throwing bodies into the air and crushing bone under its heavy tires."Keep driving!" Leo yelled from the back seat, holding onto the safety strap as the truck bounced wildly. "They are climbing onto the hood!"Lain slammed his foot harder on the gas pedal, ignoring the black blood splashing against the windshield. Two fast mutants smashed through the side windows, their long claws reaching inside toward Lain's neck."Void Sovereign, clear the roof!" Lain commanded, summoning his level-eight helper right above the vehicle cabin. The six-winged warrior appeared on the roof, its energy blades slicing the climbing mutants into pieces.The heavy truck burst through the final blockade of cars, breaking onto the open highway. Lain looked in his side mirror and saw hundreds of infected running behind them, unable to match their speed."We made it pa
Chapter 14: The Flooded Vault
The rushing water hit Lain’s knees, nearly knocking him off his feet. He grabbed Leo’s arm and dragged him away from the burning electrical net that was still sparking."Get to the stairs!" Mavis screamed, pushing open a heavy emergency door that led upward. The water level was rising fast, bubbling with yellow foam from the broken tanks.Behind them, the Void Sovereign stood firm against the falling concrete blocks. The giant spider monster thrust three mechanical legs through the ceiling, trying to pin the helper down.The alien spider fired its red laser, vaporizing a row of steel pipes instantly. A thick cloud of hot steam filled the room, making it impossible to see the exit gates."I can't feel my legs, Lain," Leo groaned, leaning heavily on Lain’s shoulder as they climbed. "The shock from that corporate net totally fried my muscles.""Just keep moving your arms," Lain said, lifting Leo up the slippery metal steps. "Mavis, hold the flashlight straight so we don't trip on the bro
Chapter 13: The Reservoir Gate
A loud splash echoed from the dark pipe behind them, followed by wet scratching sounds. Lain stopped and turned his flashlight back toward the way they had just come."They are inside the sewers with us," Leo whispered, lifting his heavy iron pipe. Mavis stepped between Lain and Leo, her light shaking against the wet brick walls."How many do you think followed us down?" Mavis asked, checking her medical bag. Lain did not answer and immediately opened his blue system interface to check his options.Current Points: 270.Squad: Phantom Bladewright (Lv. 7), Obsidian Behemoth (Lv. 7).The screen flickered slightly as the scratching noises grew closer and much louder."There are too many to count," Lain said, closing the digital menu. "We need to run straight toward the main reservoir gate before they trap us in this pipe."They sprinted through the knee-deep water, their heavy boots kicking up waves of black sludge. The smell of rotten meat grew stronger as the horde gained ground behind
