When the clues seemed to be swallowed up by darkness and everyone was in despair, the FBI's professional laboratory seemed to have a ray of hope in the chaos. The technicians were like warriors racing against time, racing against time to put the DNA samples extracted from the dead found in the basement into the most sophisticated testing instruments. They stared at the data jumping on the screen, their eyes focused and nervous, beads of sweat rolled down their foreheads, but they wiped them off flawlessly, fearing that a negligence would make this hard-won clue sink into the sea again. When the final test results appeared in front of everyone like a thunder, Li Yi felt a bone-chilling chill from the soles of his feet straight to the top of his head, instantly spreading to his whole body, making every pore of his body shrink. The identity of the deceased turned out to be Charles, who was reported missing by his family 9 years ago! This news was like a boulder thrown into a calm lake, instantly stirring up thousands of waves and impacting the hearts of everyone present. Li Yi's hands trembled slightly. He quickly searched through the pile of materials, his eyes eager and a little panicked. As the pages turned, an amazing coincidence, like the whisper of a devil, exploded in his ears: Charles and Chuck not only had birthdays in the same year, but also had birthdays corresponding to Pisces and Aquarius, which accurately corresponded to the zodiac map that had appeared in his home before, like a ghostly curse! In an instant, Li Yi's mind was like lightning and thunder, and the mysterious, weird and thrilling scenes he had experienced in the past came one after another. He instantly realized that this was by no means an ordinary criminal case, nor was it an accidental murder, but a bloody murder that was carefully planned and long-planned, hidden in the depths of darkness. The murderer seemed to follow some kind of ancient and evil contract, strictly following the established order of the zodiac. Every year, like a ghost, he quietly selected a victim whose birthday perfectly matched his birthday, and used their fresh lives to satisfy his twisted sacrificial needs. According to this calculation, this inhumane killing had already begun silently many years ago, and what they found now was just the tip of the iceberg hidden under the dark Arctic Ocean. According to this cruel and ruthless law, at least 8 innocent people are still under the shadow of death, their lives hanging by a thread, their lives hanging in the hands of others. Time seems to be wound up, so tight that it is suffocating and urgent. Li Yi and a group of FBI agents are like ignited rockets, rushing to the place where Charles' parents live. Along the way, the police car is like a roaring steel beast, whistling past, and the police lights flashing dazzling red and blue light, cutting through the gloomy sky. But Li Yi, who was sitting in the car, felt as if he was weighed down by a lead block, and his mood was extremely heavy. He knew that he was about to face a pair of parents who had lost their child for many years and were immersed in the abyss of endless grief. He had to carefully dig out useful clues that might be hidden, but he couldn't cruelly evoke their painful memories that had already been riddled with holes. This was undoubtedly a balance that was extremely difficult and treading on thin ice. The house where Charles' parents lived stood alone on the edge of the town, like an old man in his twilight years. It was a slightly old two-story building with peeling paint on the exterior wall, revealing mottled bricks and stones, like the tears of the vicissitudes of time. The surrounding courtyard seemed to be forgotten by time, with weeds growing wildly. The weeds higher than the knees rustled in the breeze, as if countless wronged souls hidden in it were whispering, revealing a sense of desolation and loneliness, and filled with endless sadness. When Li Yi stepped forward and rang the doorbell, the crisp bell sounded like a death knell in this dead space, echoing for a long time. After a long time, the door slowly opened, and a woman with a haggard face and empty eyes, as if her soul had been drained, appeared at the door. Her hair was draped over her shoulders in a mess, and a few strands of silver hair were particularly dazzling in the dim sunlight, like frost in winter. The wrinkles on her face were like deep ravines cut by the years with a carving knife, each of which was full of sadness and vicissitudes, telling the torment and pain she had endured over the years. Seeing the uniformed agents, her body seemed to be electrocuted and trembled slightly. A trace of imperceptible fear and expectation flashed in her eyes for a moment, which was the last hope of a mother for her child in the abyss of despair. "Have you... found Charles?" The woman's voice was hoarse and weak, as if it was squeezed out from the depths of her throat by thousands of difficulties and obstacles, with endless fatigue and sadness, and every word was like a heavy hammer, knocking on everyone's heart. Li Yi walked forward and gently held the woman's cold hand, which was as cold as a dead branch. He tried to speak as gently as the warm spring sun, trying to dispel the haze in her heart: "Madam, we are investigating with all our strength. We have some new clues. I hope you can help us." Stepping into the house, the dim light was like thick ink, which made people feel a little depressed and breathless. The walls were covered with photos of Charles from childhood to adulthood, from the innocent and innocent appearance of a baby, like an angel descending to the earth, to the sunny, handsome and energetic figure of a teenager. Each photo seemed to be a beautiful time frozen in time, but now it has become the most painful memory in the hearts of his parents, like a sharp knife, repeatedly stabbing their broken hearts. After a patient questioning that seemed to wear away a stone, Charles' father, a taciturn, hunched old man who seemed to be crushed by the burden of life, slowly spoke: "On the day Charles disappeared, he said he was going to the town library to borrow books, and he never came back. We searched all the places he might have gone and asked everyone who knew him, but there was no news. After calling the police, the days passed and hope became increasingly slim..." The old man's eyes were red, and tears were rolling in his eyes, like a flood about to burst the dam, but he resisted the urge to let them fall. That was the last stubbornness and strength of a father. Li Yi looked around, like a keen hound, and keenly noticed an old book on astrology on the bookshelf. The cover of the book had turned yellow, as if eroded by time, and the corners were slightly curled up, as if telling the past that had been repeatedly read. He picked it up gently and opened it. There were many pages with folded corners. Most of the marked contents were related to the zodiac. Those mysterious patterns seemed alive, and they seemed to flicker strangely under the dim light. "Excuse me, is Charles interested in astrology?" Li Yi asked softly, as if he was afraid of disturbing the sleeping ghost. The woman was slightly stunned, as if she was awakened from a long-lost memory, and then nodded: "He liked to look at the stars when he was a child. When he grew up, he became more and more fascinated by these mysterious things, and often discussed them with some friends who had the same hobbies." This clue was like a firefly in the dark, which moved Li Yi's heart. He felt that he was one step closer to the truth hidden behind the heavy fog. After saying goodbye to Charles' parents, they came to the railway where Charles disappeared, like travelers driven by fate, according to the information provided by the old man. It was a long-abandoned railway, like a giant dragon skeleton abandoned by the world, lying in a desolate land. The railroad tracks were rusty, as if they were stained with blood and dried up. The sleepers were rotten and broken, as if they were the remains of a body that could not bear the weight. The weeds on both sides were taller than people, rustling in the wind, as if countless wronged souls were whispering and crying, and there was an eerie and dead atmosphere. Li Yi and the agents were like adventurers who had entered a forbidden land. They searched carefully in the grass, taking every step with extreme caution, as if there was an abyss under their feet, for fear of missing any clue as tiny as dust. Suddenly, an agent was startled by a demon and exclaimed, "This way!" Everyone gathered around quickly as if they had heard the horn of the assembly, and saw a skeleton in a low-lying area. The bones were arranged in the shape of a sheep, with the head held high, as if roaring silently at the sky. The two arm bones simulated the front hooves of a sheep, and the two leg bones were bent, just like the hind legs of a sheep. There were some dried bloodstains on the surrounding soil, like a bloody and weird sacrifice picture, which made people shudder, as if they were at the altar of the devil. Li Yi recognized at a glance that this was the symbolic shape of Aries, which was exactly in line with their inference, as if the ruthless hand of fate once again put the truth in front of them. "It seems that the murderer's footsteps have never stopped." Li Yi clenched his teeth, as if he was going to bite his teeth to pieces. The anger and urgency in his heart were like a surging tide, becoming stronger and stronger. He knew that every second he delayed would put the next victim in more danger, as if he was racing against the god of death, but the god of death seemed to have taken the lead. At this time, the sun was setting, and the afterglow seemed to be stained red by blood, dyeing the barren railway blood red, as if foreshadowing that this battle with the mysterious evil forces was about to enter a more cruel and bloody stage... They were like guards escorting treasures, and quickly returned to the headquarters with the bones. The technicians once again engaged in intense work like a battlefield charge, trying to find more breakthroughs from this new evidence, as if looking for a ray of hope in the darkness. Li Yi sat alone in the conference room, facing the table full of information and photos, like a wise man in deep thought, and fell into deep thought. He knew that the murderer must be extremely cunning, like a ghost hidden in the dark, with a deep understanding of astrology and mysterious rituals, and was able to hide his whereabouts for a long time, select and kill victims without being known, like a reaper in the dark. Next, they not only have to speed up the investigation, like a flying man racing against time, but also find suspicious people from astrology enthusiasts, mystical societies, and people who had intersected with Charles and Chuck in the past, like looking for a needle in a haystack, to stop this brutal killing from spreading, as if guarding the last light of hope in the world. Night falls quietly, the lights of the city gradually light up, like stars, but the light of hope in Li Yi's heart is still swaying hard in the darkness, like a candle in the wind. For those lives that have not yet been killed, he must become the dawn that breaks through the darkness...
