Inside the secret lab 300 meters underground, 17-year-old Experiment Chu Yun shivered. He stared at another teenager in the glass chamber who looked exactly like him, covered in metallic scales that glowed with green light. As the alarm sounded, Chu Yun suddenly strangled the clone's neck with the umbilical cord connecting them, and the culture fluid suddenly solidified into a meridian diagram from an ancient medical book.
"Stop immediately!" A mechanical warning sounded over the radio. As Dr. Shen rushed in in his white coat, he saw Chu Yun gnawing at the clone's internal organs - the flesh and blood turned to metallic liquid at the entrance, etching strange prophetic patterns on the floor.
Eerie chanting sounds suddenly came from the ventilation ducts, and the bulletproof glass of the lab reflected the pupils of the giant mechanical dragon. When Chu Yun turned around, metal spikes suddenly erupted from its spine, the tips flashing with the same data glow as the right eye of the protagonist Lu Li a hundred years later.
Dr. Shen tore off his clothes, revealing the ancient tattoo on his chest. He used a scalpel to cut open the clone's chest cavity, and the heart he pulled out was beating with an electronic code: "This is the genetic marker Dr. Lin left behind. They have transformed you into a humanoid key!"
As Chu Yun's metal tailbone stabbed into the console, the circuit boards all over the lab suddenly became patina. The genetic map on the screen turned into the pattern of an ancient golden scepter, and what came out of the vents was no longer cold air, but fragments of armor and bones with a fishy smell.
"Father... Save me..." The dying clone suddenly let out the voice of Chu Yun's childhood. Dr. Shen was horrified to find that the radiation-proof walls were letting out the sounds of the old shipwright's horn, and those sounds were slowly turning his body into metal.
As the giant claws of the mechanical dragon tore through the elevator shaft, Chu Yun pushed the last clone into the escape pod. As the hatch closed, he saw images of future Lu Li battles flash in the clone's eyes, and the escape pod's hull lit up with the laser pattern of mysterious symbols.
The Wuhan Yangtze River Tunnel was transformed into the digestive organs of the Mechanical Monster Snake. Archaeologist Su Evening Qing realizes that ancient bamboo slips are being transformed into electronic components as she struggles with the viscous metallic gastric juices. She uses a broken bone to carve the word "escape" into the bamboo slips, and the entire tunnel suddenly begins to wriggle in the opposite direction.
"Why are you fleeing?" The mechanical snake emitted an electronic voice with a crying tone. As Su Wanqing was flung out of the tunnel, she saw a huge metal womb rising from the ruins of the city - it was an incubator that had been converted into a technology center, with countless fetal projections floating on its surface.
When the armored car driven by Dr. Shen crashed through the incubator, Chu Yun was ripped apart by the deadly scales of the mechanical dragon. Its blood dripped onto the ground, etching the floor plan of Dr. Lin's lab. As the dragon's blood splashed onto the tattoos on Dr. Shen's chest, the festering lines suddenly glowed blue.
As the metal womb exploded, a hundred thousand cloned embryos formed a twin snake totem in the air. Chu Yun grabbed one of the embryos and found that the umbilical cord was connected to Dr. Lin's brain. When he bit off the umbilical cord, the entire Yangtze River resounded with a baby's cry, a sound that echoed simultaneously through WWII-era Hiroshima and a future Mars base.
When Su Wanqing climbed out of the ruins, the bamboo slip in her hand suddenly oozed black oil, showing the future image of "Lu Li Beheading the AI". She didn't notice that the same electronic pattern as Chu Yun's tail stinger appeared on her stomach.
Dr. Shen stared at the tattoo on his chest and realized that the ancient pattern was seeping into his heart. As he coughs up his first mouthful of metallic blood, 108 large mechanical bells rise from the lake - each trapped with a fragment of Dr. Lin's daughter's consciousness humming the off-key Frozen theme song.
