With full of doubts and urgency, everyone followed the clues provided by Philip and headed towards the old mansion without stopping. Outside the car window, the dark clouds were like a heavy lead plate, pressing heavily on the sky, covering the entire sky tightly, as if covering the earth with an ominous veil. The strong wind was like a group of mad demons, whistling, roaring, and whipping the car body with fangs and claws, as if issuing a stern warning not to allow them to get close to the place where the secrets were hidden. The lead-gray clouds hung low, as if they would be overwhelmed and collapse in the next second, ruthlessly crushing everything in the world in this extremely depressing atmosphere. When the mansion came into view, Li Yi's heart couldn't help but tighten. It was like a giant beast lurking in the dark abyss and sleeping for a thousand years. It exuded an ancient and mysterious atmosphere. Just a glance from a distance could make people feel the heaviness and gloom of the years. The outer wall of the mansion was covered with moss, which was layered and wetly attached to it, just like scars left on the wall by the years with its ruthless chisel, mottled and decayed. Many bricks and stones on the wall had become loose and peeled off, and were exposed unevenly, as if silently telling the vicissitudes and hardships of the past, and witnessing countless dusty stories. The towering spire pierced the sky, like a giant hand from hell that tried to tear the sky apart. It looked particularly eerie and terrifying under the gloomy sky, as if it wanted to completely cover the last ray of light in the sky. Li Yi took a deep breath, trying to calm the waves in his heart, and then resolutely stepped into the gate of the mansion first. In an instant, the door hinge made a sharp and long "creaking" sound, as if it was an evil spirit that had been sleeping for a long time and imprisoned in the darkness, and suddenly woke up and roared angrily. It echoed in the empty and lonely front hall for a long time, startling the dust that was sleeping in the dead silence. The dust was like a group of frightened ghosts, dancing and circling in the weak light that came through the cracks, which made people shudder. Everyone walked in carefully, and the strong flashlights in their hands shot out bright beams of light, trying to dispel the thick darkness in front of them. However, the weird atmosphere that followed them like a shadow and seemed to be real was like a thorn in the bone, and it could not be dispelled. Every beam of light passed by, as if it accidentally disturbed the evil spirits hiding in the dark and watching covetously, causing everyone's backs to chill and their hair to stand on end. At this moment, Li Yi's eyes seemed to be drawn by a mysterious force, and he was instantly attracted by a looming sign on the wall. He subconsciously took a closer look, and his heart sank suddenly - it was an equally mysterious sign, exactly the same as the symbol of the black cat case he handled when he first came to the United States! In an instant, memories surged into his mind like a surging tide. The black cat case was also full of weirdness and blood. Various bizarre and unimaginable death phenomena and mysterious forces that could not be explained by science were intertwined and entangled, causing him and his teammates to suffer a lot during the investigation. In that case, a black cat with a strange death would always appear strangely beside each victim, with its eyes wide open, as if it had witnessed some extremely terrifying scene before its death, and some symbols closely related to mysticism would inexplicably appear on the corpse, like a mark left by some evil curse, exuding a chilling breath. Although the case seemed to be closed in the end, it actually left many unsolved mysteries like a tangled mess. Now, this sign reappeared without warning, like a thread hidden in the deepest darkness, connecting two seemingly unrelated and irrelevant cases together. The hidden meaning behind it made him shudder, as if there were a pair of invisible eyes staring at them in the darkness. Suppressing the uneasiness in his heart like a stormy sea, Li Yi led the team to continue to explore this maze-like castle. With every step, the wooden floor under his feet would make a "creaking" sound, and the sound was like countless wronged souls whispering and crying, complaining and sad, drilling straight into people's hearts, making people's heartbeats accelerate involuntarily, as if the heart would burst out of the chest at any time. The house was filled with an old and decayed smell, which seemed to drift out from the deepest ancient tomb underground, mixed with a faint smell of decay, suffocating, as if instantly placed in a huge tomb buried with countless secrets. Suddenly, a faint red light shone from a room in front, which looked particularly strange in this dark mansion that seemed like an endless abyss, as if a blood-red eye was peeping at them in the dark. Li Yi and others quickly looked at each other, their eyes full of vigilance and determination, and then walked towards the room without hesitation. The moment they stepped into the room, the scene in front of them made everyone gasp - in the center of the room, a huge lion specimen stood there. The specimen, which was originally well-made and should have been lifelike, now looked extremely hideous in this weird atmosphere. Its big eyes like copper bells seemed to be injected with evil souls, staring at everyone, as if to see through everyone's souls. What was even more horrifying was that blood was slowly seeping out from all parts of the lion's body! Drop by drop, the blood was bright red, as if it had just flowed out of a human body, with a boiling temperature, gathering on the ground into a dark red pool of blood, emitting a pungent smell, as if the lion had just experienced an extremely cruel and bloody fight, and life was gushing out of its body, leaving behind this tragic and terrifying scene. Before everyone could recover from the shock, a mural on the wall next to them attracted their attention again. The mural depicted a girl in a white dress. The girl had a beautiful face, picturesque eyebrows, and clear and smart eyes, as if she could reflect the most beautiful things in the world. But at this moment, those eyes were like being cursed by the devil, and blood was gushing out! Blood flowed down the wall, like a girl's silent weeping, or like a painting that was originally flawless and praised by the world, but was suddenly ruthlessly tainted by evil, which made people feel heartbroken and filled with grief and indignation. "What is going on?" A team member whispered in horror, his voice trembling violently, like a leaf shivering in the autumn wind, and the flashlight in his hand also shook violently, making the originally still shadows around them seem to come alive in an instant, turning into terrifying monsters with bared fangs and claws, which made people more and more frightened. Li Yi did not answer, his eyes seemed to be attracted by a magnet, staring at a secret compartment under the mural. With the experience of handling cases accumulated over the years in the mysterious cases, he keenly realized that there must be something strange there, and perhaps the key clues to the truth of the case were hidden. He walked forward slowly, his footsteps were so light as if he was afraid of disturbing the "evil spirit" in the house. He reached out and pushed the secret compartment tentatively. With a dull sound, the secret compartment slowly opened. A strong smell of blood that seemed to be real came to their faces. When everyone looked closely, they saw two people curled up inside that they had never seen before! The two people's bodies were twisted and deformed, as if they had been manipulated by an extremely powerful, cruel and violent force. Their limbs were bent at a weird angle that was beyond imagination. Obviously, they suffered great pain. The skin was a blue-gray color and lifeless, as if the soul had been taken away from the body, leaving only this cold body. Their death was completely different from the victims found before, but it was also revealed with an indescribable weirdness, as if it was a warning from another dark world. Li Yi instantly realized that these were the seventh and eighth victims, corresponding to Leo and Virgo. The murderer once again cruelly sacrificed two fresh lives in the mysterious and evil order of the zodiac. This bloody sacrifice became more and more crazy, like a countdown from hell. Every second tightly gripped everyone's heart, making people breathless. "We can't let him succeed again!" Li Yi gritted his teeth and roared, with angry flames burning in his eyes, and the flames seemed to be able to dispel the thick, ink-like haze in the mansion. He knew that time was running out. Every moment of delay would cause the murderer to strike again, and new innocent lives would be slaughtered. They must race against time to find the key thread from this mystery that is as big as a mountain and as big as a sea, pull out the real murderer hidden in the darkness, and stop this inhumane killing from spreading. Otherwise, more innocent lives will fall victim to this evil sacrifice, and the consequences will be disastrous, and the entire city will be shrouded in the shadow of fear... The team members acted quickly, some quickly took out their cameras to take pictures for evidence, and the flash of the camera frequently lit up in this dim room, like lightning that cut through the night sky, trying to freeze this sinful moment and record every detail clearly, not allowing the murderer any chance to escape the blame; some put on gloves and carefully examined the victim's body, gently stroking the cold skin with their fingers, their eyes focused and sharp, hoping to find some clues, even the slightest wounds and the most inconspicuous traces, which could become the key to solving the case and a powerful weapon for them to catch the murderer. Li Yi looked around, his eyes like a searchlight, trying to find clues related to the murderer from the layout and furnishings of this room. His eyes swept over the dusty ancient books on the bookshelf. The covers of those ancient books seemed to hide the secrets of the years. The titles had long been blurred and eroded beyond recognition by time, but they still exuded a mysterious atmosphere, as if telling an ancient story; some occult instruments placed in the corners had strange shapes, some were like twisted branches that looked like living things, and some were like strange rune carvings, containing elusive power, as if each one carried an unknown dark history. He thought to himself: How many unknown secrets are hidden in this mansion? Why did the mysterious man choose to continue his atrocities here? Outside the window, the wind was still howling, blowing the branches wildly, as if countless hands were waving into the mansion, and as if covering up some unspeakable secrets. Li Yi tightened his collar, trying to resist the bone-chilling cold, and once again cast his eyes on the bleeding lion specimen and the weeping girl mural. He knew that the truth was behind the thick fog, and they had to break through all obstacles to uncover it... Just as everyone was concentrating on searching for clues, a gloomy laugh suddenly echoed in the room. The laugh seemed to come from the underworld, like the roar of a demon, which made people's hair stand on end. The team members looked at each other in horror, their eyes full of panic and fear, looking around for the source of the sound, but found no one. Li Yi clenched the flashlight in his hand, and looked around vigilantly, like a cheetah guarding his territory. He knew that the evil spirits in the mansion did not seem to want them to succeed easily, and a more thrilling contest had just begun...
