Forensic Doctor: Finding the Way Back to the Mystery of Ancient Realms

As the first rays of morning light penetrated the mist, Xu Youran and Situ Han returned to the scene where the tram disappeared. This time, they brought professional investigation tools and a technical team, vowing to uncover the mystery of the disappearance of the tram.

Xu Youran walked slowly along the tram track, her eyes as sharp as a hawk, not missing any slight abnormality. Suddenly, she stopped, squatted down, pointed at a barely visible scratch on the track and said, "Someone has tampered with it here."

Upon hearing this, Situ Han immediately stepped forward and carefully observed it with a magnifying glass. As expected, it was a scratch that almost blended into the color of the track, and it was difficult to detect without careful observation. "This is a mark left by some special tool, and it is definitely not accidental." He said in a deep voice.

Afterwards, the technical team used high-tech equipment to conduct a comprehensive scan of the scene, and the results showed that there was weak electromagnetic interference around the scene a few minutes before the tram disappeared. This discovery made the two people nervous. Could the disappearance of the tram really be related to supernatural forces?

In order to obtain more clues, Xu Youran and Situ Han decided to act separately and go deep into every corner of S City to conduct inquiries and visits.

Xu Youran first went to the victim's home, a middle-aged woman whose husband was one of the passengers on the tram. When she saw Xu Youran, she burst into tears: "I just hope he can come back safely. He is the pillar of our family!"

Xu Youran comforted her gently and asked about the details of what happened before the tram disappeared. From her narration, Xu Youran learned an important piece of information: the victim mentioned a mysterious stranger before the tram disappeared, who always wandered around the station and behaved strangely.

On the other hand, Situ Han went to the tram factory and found the technician named Li Gong. Facing Situ Han's questioning, Li Gong finally let go and revealed that he had participated in a secret project to study the "stealth" technology of trams. However, due to the immaturity of the technology and great safety risks, the project was eventually terminated.

"But I suspect that someone is secretly continuing this project." Li's voice trembled, "They want to use this technology to achieve ulterior motives."

Based on the clues provided by Li Gong, Xu Youran and Situ Han decided to turn the focus of their investigation to the mysterious organization. They used all available resources to track down the organization's clues.

In the process, they encountered many obstacles and dangers. Once, when they were tracking a suspect, they were besieged by a group of unidentified people. In the fierce confrontation, the two relied on their outstanding wisdom and courage and finally escaped from danger.

"These people are well-trained and are obviously professional killers." Situ Han wiped the blood from the corner of his mouth, his eyes grim, "They will stop us from revealing the truth at all costs."

As the investigation deepens, Xu Youran and Situ Han discover that behind this mysterious organization lies a more complex entanglement of forces and struggles of human nature. They use people's fears and beliefs to weave lies and conspiracies one after another.

During a late night infiltration operation, they accidentally overheard a conversation among members of the organization. It turned out that the leader of the organization was a fanatical believer in supernatural powers. He firmly believed that through special rituals and "invisibility" technology, he could realize his dream of immortality and world domination.

"These people have been brainwashed. They have completely lost themselves." Xu Youran felt a chill. "But we must find their weaknesses and destroy this evil organization."

After several days of hard investigation, Xu Youran and Situ Han finally found the real reason why the tram disappeared. It turned out that the mysterious organization used special technology to create an electromagnetic pulse device. When the tram passed through a specific area, the device would be activated, instantly distorting and hiding the tram and the surrounding space.

In order to verify this speculation, they teamed up with the technical team to conduct a series of experiments and simulations. Finally, in a thrilling actual combat exercise, they successfully located and destroyed the electromagnetic pulse device, making the disappeared tram reappear in front of everyone.

When the tram slowly drove back to the platform, the crowd around it burst into thunderous applause and cheers. However, Xu Youran and Situ Han did not look very happy. They knew that this was just the beginning and the real challenge was still to come.

Just as everyone was immersed in joy, a mysterious note quietly appeared in front of Xu Youran. The note read: "Although the mystery of the tram has been solved, the real danger has just begun. In S City of the Republic of China, there are still many unsolved mysteries waiting for you."

Xu Youran and Situ Han looked at each other and understood what this meant. They knew that the next case they would face would be a more complicated and dangerous one.

"Let's go, Commander Situ." Xu Youran smiled gently, with a determined light in her eyes. "No matter how many unknowns and challenges there are ahead, we will go hand in hand until all the truth is revealed."

As night fell, the old residential area of ​​S City was once again shrouded in a mysterious fog. Xu Youran and Situ Han did not return to the police station immediately, but drove to the old residential area mentioned in the mysterious note. Their hearts were full of doubts and uneasiness, but also full of curiosity and desire to explore the unknown.

The old residential area is located on the edge of S City. The architectural style is simple and old, as if every brick and tile carries a heavy history and secrets. In the night, the streets of the old residential area seem particularly deep and quiet, and only the occasional barking of dogs in the distance breaks the tranquility.

Xu Youran and Situ Han walked along the winding alley and finally arrived at the mansion that had been abandoned for many years. The door of the mansion was closed, and the copper ring on the door had long been eroded by time. Situ Han gently pushed open the door, and a damp breath rushed towards him, accompanied by a gust of cold wind.

The two entered the house cautiously, only to see that it was overgrown with weeds and spider webs, and it was obvious that no one had been here for a long time. However, deep inside the house, a low and strange sound was faintly heard, like someone whispering, or like the sound of some ancient machinery running.

"There is indeed something wrong here." Xu Youran said in a low voice, her eyes moving through the darkness, looking for the source of the sound.

Suddenly, a strong electric current came from under their feet. The two were startled and stepped back. The stone slab on the ground where they had just stood suddenly cracked, revealing a dark hole. Under the hole, there seemed to be some unknown horror and secret hidden.

"It seems that we have found a new clue." Situ Han analyzed calmly, "This cave entrance is likely related to that mysterious organization. We need to go down and find out."

Xu Youran nodded, and the two quickly prepared ropes, flashlights and other equipment, and carefully climbed down the cave. Below the cave entrance was a narrow and winding underground passage, and the walls on both sides of the passage were engraved with strange symbols and patterns, which made people shudder.

As they continued to go deeper into the underground passage, the strange smell became stronger and stronger. Suddenly, a piercing scream broke the silence of the passage, and then a black shadow rushed out from the darkness and pounced on them.

"Be careful!" Situ Han pulled Xu Youran aside and pulled out his pistol, aiming at the shadow. However, when his flashlight illuminated the shadow, they were surprised to find that it was a human being twisted by a horrific ritual!

The two looked at each other and realized that there was a more terrible secret hidden here than they had imagined. They continued to move forward and finally came to a huge underground cave. In the center of the cave was an ancient altar, on which were placed various strange objects and offerings, and those strange symbols and patterns covered the entire cave wall.

At this moment, a low and majestic voice came from the depths of the cave: "Welcome to my world, Xu Youran, Situ Han. Do you think you can solve all the mysteries? Haha, you have only stepped into a deeper abyss..."

As the voice sounded, a figure slowly walked out from the depths of the cave. It was a mysterious man in a black robe, with a silver mask on his face, revealing only two eyes that were gleaming with a faint light.

"Who are you?" Situ Han asked in a deep voice, holding the gun tightly in his hand, ready to deal with possible danger at any time.

"Me?" The mysterious man sneered, "I am the protector of this city, and also its destroyer. I have witnessed its rise and fall, and its changes, and I also hold its fate and secrets. And you are about to become the witnesses and victims of all this..."

As the mysterious man finished speaking, the entire cave began to shake violently. Xu Youran and Situ Han realized that they had been involved in a larger and more complicated conspiracy. And that mysterious man was the mastermind behind all of this...

As the cave shook, Xu Youran and Situ Han struggled to resist the sudden crisis. However, just when they were about to despair, a beam of light suddenly shone down from the top of the cave, giving them a glimmer of hope.

"Look! There is a way out there!" Xu Youran pointed in the direction of the light, with hope flashing in his eyes.

Situ Han nodded, and the two quickly ran towards the light. When they finally escaped from the cave and saw the light of day again, they found that the outside was in chaos. The tram in S City mysteriously disappeared again, and this time, the whole city seemed to be in panic and despair...

"This is just the beginning." Xu Youran looked at the chaotic city, her heart filled with worry and determination. "We must continue to investigate and uncover all the secrets and conspiracies of this city."

Situ Han held her hand tightly, with a determined light in his eyes: "No matter how many difficulties and dangers there are ahead, we will face them together. Because we are the guardians of S City and the seekers of the truth."

As the two gradually disappear at the end of the city, a new mystery and challenge awaits them... And what truth and secrets are hidden behind all this? Please look forward to the next chapter - The case of the missing tram in S City during the Republic of China.
