Thee "poison" in Xin’s veins felt like liquid lead as he climbed the service ladder toward the Spire’s observation deck. Every heartbeat sent a ripple of violet light through his skin. Since the day of the alien flowers, his senses had changed. He didn't just see the world; he felt it. He could feel the cold metal of the Spire groaning under the wind, and he could feel Mei’s heartbeat hammering in her chest ten floors below him.​"Xin, stay with me," Captain Han’s voice came over the radio. "You’re drifting. Don't let the Engine take over."​"I'm here," Xin grunted, pulling himself onto a narrow ledge.​They were back at the Spire—the giant needle that had pierced the heart of Jiangnan. After the attack at the Stadium and the blooming of the Siren flowers, Han realized they couldn't just play defense. They had to understand what this building actually was. It wasn't just a skyscraper; it was a key.​Mei followed Xin, her belt clinking with sensors and cables. She looked up at the core

Thee golden light inside the Spire didn't feel like a hug anymore. It felt like a cage.​Xin could feel the Black Spire far below the city. It was like a second heart, but it didn't beat with life. It beat with a cold, hollow thud that made the very air feel thin.​"Xin, talk to me!" Mei’s voice was sharp with panic. "The sensors are going crazy. The ground temperature is dropping to forty below zero!"​"It’s starting," Xin whispered. His voice vibrated through the Spire’s walls. "The Harvest. They aren't just taking energy anymore, Mei. They’re taking the people."​Through his Pulse Sense, Xin saw it happen. In the refugee camps, in the small apartment blocks, and even in the Resistance base, the shadows began to move. They didn't look like monsters. They looked like puddles of black ink on the floor.​"Captain! Look out!" Xin roared.​Inside the observation deck, the shadow beneath Han’s feet suddenly stretched upward. It wrapped around his ankles like cold, wet snakes.​"Get back!"

The Central Plaza was a graveyard of smoking metal and black dust. The red glow from Xin’s armor bathed the ruins in a color like dried blood. He stood in the center of the destruction, his chest heaving, his eyes fixed on the darkness of the North District.​He didn't look at Jackson’s body. He didn't look at Han’s bleeding leg. He only looked for the next thing to kill.​"Xin! Stand down!" Han yelled, his voice cracking. He tried to limp toward the boy, but the heat coming off the red armor was like standing next to a furnace. "It’s over! They’re gone!"​Xin’s head snapped toward Han. For a terrifying second, the red blades on his forearms hummed, ready to strike.​"Captain, get back!" Mei screamed, running from the Spire's control hub. She was holding a small, glowing device—a modified stabilizer. "He’s not processing who we are! The 'Berserker' code is looping!"​But Xin didn't attack. A high-pitched, human scream echoed from three blocks away. It was a girl’s voice, coming from th

The Isolation Sector of the Spire felt like a tomb, but it sounded like a factory. Deep in the bowels of the structure, where the gray stone met the ancient machinery of Earth-6, Xin stood inside a glass cylinder.​He wasn't alone.​The Architect’s Daughter—or the holographic ghost of her—floated on the other side of the reinforced glass. In her hand, she held a vial of swirling, iridescent mercury. It shifted from silver to violet to a deep, bruised crimson.​"The Null-Cage Mei is building will only kill you, Xin," the hologram whispered, her voice bouncing off the cold walls. "My father didn't design it to save you. He designed it to delete a failed experiment. But this..." she held up the vial. "This is the Evolution Liquid. The pure essence of the 99 Earths."​"I don't want more power," Xin rasped. The red veins on his chest were thumping against the glass, hungry for the liquid.​"It’s not power. It’s stability," she countered. "Drink it, and the 'Monster' becomes the 'Master.' R

Thee warm rain should have been a relief, but in the North District, it felt like a funeral shroud. The steam rising from the cracked asphalt turned the narrow alleys into a maze of white mist and jagged shadows.​Xin leaned heavily against a brick wall, his breath coming in ragged gasps. His golden skin was dull, the "Thermal Overdrive" having drained him to the marrow. Next to him, Mei was trying to fix a jammed scanner, her fingers slick with rainwater and grease. Captain Han stood at the mouth of the alley, his rifle raised, his eyes scanning the fog.​"The Spire is five blocks away," Han whispered, his voice tight. "But the 'Cold Spots' are closing in. We’re being squeezed, Xin."​Xin tried to trigger his Thermal Sight, but his vision only flickered with static. "I can't see them, Captain. The Engine is... silent. It’s like it’s hiding."​"It’s not hiding," a voice hissed from the fog.​It wasn't a monster. It was human.​Suddenly, the rooftops on both sides of the alley erupted
