Lin Yu gripped his gun tightly and shouted towards the ventilation duct, "Who's there!" Only the echoing footsteps of panicked fleeing echoed in response. In the basement, the bound woman sobbed, her eyes filled with terror. Lin Yu signaled to his colleagues to untie her quickly, while simultaneously assigning two men to chase after the mysterious figure in the ventilation duct.

The woman's name was Su Qing. According to her, Chen Qiang and she had been friends for many years. A few days ago, Chen Qiang suddenly approached her, claiming that he had discovered a shocking secret while investigating Factory 719, a secret that might threaten the interests of certain people, and warned her to be careful. But before Su Qing could ask any further questions, she was kidnapped by a group of mysterious people and brought here. "Chen Qiang said there's a hidden laboratory underground in the factory... they're doing some shady experiments..." Su Qing's voice trembled, and tears welled up in her eyes.

Lin Yu frowned deeply; it seemed the conspiracy behind Factory 719 was far more complex than he had imagined. Just then, his colleague, who had gone to pursue the mysterious figure, ran back breathlessly, saying that the mysterious person was extremely familiar with the factory's layout and had vanished without a trace among the intricate pipes. Lin Yu pondered for a moment and decided to continue searching the factory, hoping to find clues related to Chen Qiang's death and the laboratory.

They continued along the basement passageway, the walls of which were covered in strange graffiti, arrows, and other illegible symbols pointing deeper into the basement. As they went further, a strong smell of disinfectant gradually masked the original stench. Suddenly, a heavy iron door appeared ahead, secured with an advanced electronic lock. Lin Yu tried to find a way to open it and discovered a small box embedded in the wall beside him; opening it revealed a fingerprint reader.

"Looks like we need to find someone who can open this door," Lin Yu muttered to himself. Just when everyone was at a loss, Su Qing timidly said, "Chen Qiang mentioned before that there's a man named Zhao Hui who might know many of the factory's secrets. Maybe his fingerprints can open this door." Lin Yu immediately contacted the police station and asked his colleagues to investigate Zhao Hui's information and whereabouts.

While waiting for news, they searched the vicinity and found fragments of experimental records in a secluded room. From the blurred handwriting, Lin Yu and his team deduced that Factory 719 seemed to be conducting some kind of genetic modification experiment, and the subjects were likely nearby residents. This might be the reason Chen Qiang was murdered—he had discovered this terrifying secret.

Soon after, news came from the police station that Zhao Hui had been a key technical staff member at Factory 719. After the factory closed, he became increasingly secretive, recently frequenting a small clinic in the south of the city. Lin Yu left some colleagues to continue the investigation at the factory, while he, along with Su Qing and several other colleagues, headed to the south of the city. At the clinic, they found Zhao Hui. Zhao Hui looked extremely haggard, and when Lin Yu identified himself and mentioned Factory 719, his eyes instantly filled with fear.

“I…I didn’t want to have anything to do with that place anymore.” Zhao Hui’s voice was hoarse. “The experiments the factory conducted back then were too crazy. I wanted to leave after I realized something was wrong, but they kept watching me…” Under Lin Yu’s persuasion, Zhao Hui finally agreed to cooperate with the police.

Back at Factory 719, Zhao Hui's fingerprints successfully unlocked the iron gate. The gate slowly opened, releasing a strong smell of chemicals. Inside was a huge laboratory, with various advanced instruments neatly arranged. Photos of experimental subjects hung on the walls, some with distorted and horrifying shapes.

On the lab's computer, Lin Yu and his team found the complete experimental records. It turned out that the factory's mastermind was attempting to create "super soldiers" with superhuman strength and obedience through genetic modification. Chen Qiang's investigation seriously threatened their plans, which is why he was killed. Just as they were preparing to gather evidence, the lab's alarm suddenly went off.

"Oh no, someone triggered the alarm!" Zhao Hui's expression changed drastically. "They'll be sending people soon." Lin Yu quickly arranged for his colleagues to copy the important evidence and prepared to evacuate. But just as they reached the door, they heard a series of rapid footsteps outside. Lin Yu told Su Qing and Zhao Hui to hide in the lab, while he and his colleagues stood ready with their guns drawn.

A fierce firefight erupted instantly. The enemy was well-trained and possessed fierce firepower. Lin Yu and his team, taking advantage of the terrain, temporarily held off the enemy's attack. However, the enemy continued to pour in, and the situation became increasingly critical. Just then, reinforcements arrived, and under the police's pincer movement, the enemy surrendered one after another.

After a thorough interrogation, the mastermind's identity was finally revealed—the chairman of a local biotechnology company. As the investigation deepened, this criminal gang involved in illegal gene experiments was completely dismantled, and the mystery of Factory 719 finally came to a close. Lin Yu stood outside the factory, watching the rising sun, his heart filled with mixed emotions. This experience made him realize that justice may be delayed, but it will never be absent, and that as a police officer, protecting the peace and tranquility of the people is his lifelong mission.
