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

In the early morning, the streets of S City were still immersed in tranquility. Xu Youran and Situ Han had already arrived at the core scene of the vampire case - a long-abandoned manor. The gate of the manor had been eroded by time and looked particularly eerie. The mysterious totem on the door looked even more eerie in the faint morning light.

"We have to be careful." Situ Han reminded softly, looking around vigilantly, holding the gun tightly in his hand. Xu Youran nodded, her eyes sharp, as if she could penetrate all disguises and see the truth.

The two pushed open the creaking door and stepped into the manor. The courtyard was overgrown with weeds, and the broken walls revealed a sense of desolation and decadence. Xu Youran and Situ Han began to act separately and conduct a detailed on-site investigation.

Xu Youran walked towards a patch of soil that looked like it had been recently turned over. She squatted down and gently pushed the soil away with her fingertips, and found a hidden entrance to the basement. She motioned for Situ Han to come over, and the two of them worked together to move a heavy stone slab, revealing the stairs leading to the basement.

The basement was cold and damp, and the air was filled with a disgusting smell of blood. Xu Youran turned on the flashlight, and a beam of light illuminated the darkness ahead. The walls were covered with dried blood, as well as some unclear claw marks and tooth marks. It was obvious that this was once a place where vampires lived.

"It seems that we have found the right place." Situ Han whispered, his tone was both nervous and excited. He noticed some pieces of clothing scattered on the ground, and it was obvious that the victim had been imprisoned here.

Xu Youran found an old diary on a worn wooden table. The cover of the diary was badly damaged, but the words inside were still clearly visible. She carefully opened the diary and began to read.

 Diary Secrets: Ancient Curse and Revenge

As Xu Youran read word by word, a piece of dusty history gradually surfaced. The owner of the diary was a nobleman named Alexander, who recorded in the diary how he was controlled by a mysterious organization and forced to participate in a series of evil rituals.

"This organization is called the 'Dark Night Council'. They claim to hold the secret of immortality, but in fact they prolong their lives by sucking the blood of others." Xu Youran couldn't help but shudder when he read this.

She continued reading and found that Alexander finally got rid of the control, but he also realized that he had been cursed and turned into an undead monster. He couldn't stand this inhuman life, so he decided to record his experience in the hope of warning future generations.

"Look here, he mentioned a name - Cassandra." Situ Han pointed to a line in the diary and said. This name caught the attention of the two because they had heard this name many times in previous investigations.

"Cassandra, is she the leader of the Council of Dark Night?" Xu Youran guessed.

Situ Han nodded, his eyes becoming serious. "It seems that our investigation has touched the core of the Dark Night Council. They will not let us go easily."

In order to get more clues, Xu Youran and Situ Han decided to go to the victim's family's residence to inquire. They first came to the home of a victim named Marian.

As soon as Marian's mother saw them, she burst into tears. She tightly grasped Xu Youran's hand, as if she had found a life-saving straw. "Please catch that monster and avenge my daughter!" Her voice was trembling, filled with endless grief and anger.

From Marian's mother's story, Xu Youran and Situ Han learned more details about the vampire attack. Marian was a lively and cheerful girl, but since a few months ago, she became mysterious and often stayed out all night. Until one day, she never came back.

"When we found her, she was already...she was already..." Marian's mother burst into tears and couldn't say anything. Xu Youran gently patted her back to comfort her.

Through questioning, they also learned that before Marian disappeared, she mentioned a woman named Cassandra, saying that she was her mentor and her idol. But this information made Xu Youran and Situ Han more vigilant.

After leaving Marian's house, Xu Youran and Situ Han began to track Cassandra's whereabouts. Through the intelligence network of the S City police, they obtained several possible hiding places of Cassandra.

As night fell, the two came to an abandoned factory. This was one of the secret places where Cassandra performed the ritual. They carefully sneaked into the factory, only to see that it was pitch black all around, with only a few faint lights flickering in the distance.

They quietly approached the location of the light and saw a group of people sitting around a huge altar, chanting spells in a low voice. On the altar were various strange objects, including the mysterious totem.

"It seems that we have found the meeting place of the Dark Night Council." Situ Han said in a low voice, his voice full of firmness and determination.

At this moment, Cassandra appeared on the altar. She was wearing a black robe and a silver mask on her face, revealing only her cold eyes. She raised the scepter in her hand high and announced loudly: "Tonight, we will welcome new members and use their blood to celebrate our victory!"

Xu Youran and Situ Han looked at each other. They knew without further ado that they were going to face a tough battle. They approached silently, trying to find the best entry point.

Suddenly, a cold wind blew, as if even the air had frozen. Cassandra seemed to have noticed something, and her eyes instantly swept in the direction of Xu Youran and Situ Han, with a sneer on her lips: "It seems that there are uninvited guests at tonight's banquet."

As she finished her words, the surrounding members of the Dark Night Council stood up one after another. Some took out daggers, while others chanted more complicated spells. The entire factory was suddenly filled with a tense and depressing atmosphere.

"Situ, are you ready?" Xu Youran asked in a low voice. There was an exquisite pistol in her hand, which she had specially prepared for this operation.

"Of course." Situ Han's answer was brief and powerful. He was ready for the fight, with unquestionable determination flashing in his eyes.

The two acted at the same time, Xu Youran was responsible for restraining those members who used physical attacks, while Situ Han used his agility and excellent fighting skills to approach Cassandra. However, the members of the Dark Night Council were not simple. They seemed to have received strict training and cooperated well, which brought Xu Youran and Situ Han a lot of trouble.

Just when the two sides were in a stalemate, an unexpected situation occurred. There was a sudden noise outside the factory, followed by the roar of sirens. It turned out that after the S City police learned of Xu Youran and Situ Han's whereabouts, they immediately organized a large-scale operation and surrounded the abandoned factory.

The members of the Dark Night Council were suddenly in a panic, realizing that they were in a desperate situation. Seeing this, Cassandra roared angrily, waving her scepter in her hand, trying to summon a stronger force to fight the police. But how could Xu Youran and Situ Han give her this opportunity? They tried their best and finally found a breakthrough, rushing straight towards Cassandra.

After a fierce battle, Cassandra was finally subdued by Xu Youran and Situ Han. She took off her mask, revealing an old and twisted face, with eyes full of reluctance and despair.

"Do you think this is the end?" Cassandra panted, "The power of the Dark Night Council is far beyond your imagination. We will be back!"

However, for Xu Youran and Situ Han, this sentence no longer posed any threat. They knew that as long as they continued to uphold justice, no matter how powerful the Dark Night Council was, they would not be able to escape the punishment of the law.

With Cassandra's arrest, the truth of the vampire case gradually surfaced. It turned out that all this was a conspiracy planned by the Dark Night Council in order to find the secret of eternal life. They used ancient curses and evil rituals to turn some people into vampire-like beings to satisfy their greedy desires.

After handing Cassandra over to the police, Xu Youran and Situ Han stood outside the factory, looking at the police car going away, their hearts filled with emotion. They knew that this was just the beginning, and there would be more challenges waiting for them in the future. But they also believed that as long as they worked together, nothing could stop them from moving forward...

Just as Xu Youran and Situ Han were about to leave, a gust of wind blew by, bringing with it a piece of paper that had been left behind. They picked up the paper and saw that it read: "In S City in the Republic of China, the mystery of the porcelain engraver is yet to be solved." This short sentence flashed through their minds like a flash of lightning, instantly reminding them of the case that was also full of mystery and weirdness.

"It seems that our next mission has arrived." Xu Youran said with a smile.

Situ Han also nodded, his eyes gleaming with anticipation. "Then let's uncover the mystery of the porcelain engraver together!"

So, the two of them set out on a journey to find the truth again, and this time, they will go to S City during the Republic of China period to unravel the secret hidden in the dust of history...
