The sunlight shone through the gaps in the curtains onto Xu Youran's hospital bed, but she did not feel the warmth. Her thoughts were like being pulled by an invisible thread, shuttling between two worlds.
Xu Youran (talking to herself, with a dazed look in her eyes): "This is impossible... How can I be here and there at the same time?"
Suddenly, the door of the ward was gently pushed open, and Situ Han appeared at the door, with both confusion and worry in his eyes.
Situ Han (whispering): "You Ran, are you awake? The doctor said you need to rest."
Xu Youran (suddenly came back to her senses and looked at Situ Han, with a hint of surprise in her eyes): "Situ Han? You... why are you here?"
Situ Han (frown): "I have been investigating the case you mentioned, but I didn't expect you to be unconscious here. The doctor said that you might be confused due to excessive psychological pressure."
Xu Youran (shaking her head, trying to clear her mind): "No, that's not the case. I'm investigating, I'm really investigating that case, and I saw a lot... a lot of things that don't belong here."
Situ Han (half-believing, half-doubting): "You mean, your so-called investigation is actually in your dream?"
Xu Youran (firmly): "It's not a dream, it's another time and space, S City during the Republic of China period. I saw the victim, tracked down the suspect, and even... I even felt that it was everything I experienced personally."
In order to verify Xu Youran's statement, Situ Han decided to use the hospital's resources to try to explain this phenomenon from a scientific perspective.
Situ Han (contacting the doctor): "I need to know all of You Ran's test results, especially the data on her brain activity."
Doctor (via video link): "Ms. Xu's brain scans did show some abnormalities, especially during her coma, her brain wave activity was unusually active, as if she was experiencing some kind of strong emotional stimulation."
Situ Han (thoughtfully): "Emotional stimulation? Could it be that she subconsciously reconstructed the scenes of that era?"
Xu Youran (eagerly): "No, I feel that it is not just a reconstruction, it is real. I can feel the wind there, the smell there, and the emotions of those people."
At the same time, Xu Youran seems to be able to "travel through time" to the S City during the Republic of China period, and her conversation with Situ Han takes place in two intertwined time and space.
Xu Youran (said to the virtual Situ Han): "We must find that secret room. The key to unlocking everything is hidden inside."
Situ Han (to Xu Youran in real life): "Youran, you need to calm down. What we need to do now is to find out the reason why you are in this situation, instead of blindly believing in your hallucinations."
Xu Youran (closing her eyes in pain): "This is not an illusion. I can feel that pain, that despair... It's like I'm experiencing it myself."
In order to find the answer, Situ Han decided to take a two-pronged approach. On the one hand, he continued to investigate Xu Youran's condition in modern S City. On the other hand, through Xu Youran's description, he tried to find relevant records from the Republic of China period in the archives.
Zhang Wei, a representative of the S City police (via video link): "Commander Situ, based on Miss Xu's description, we found some records related to the Yun family in the archives, but there are no direct clues to the secret substance."
Situ Han** (pondering): "Keep investigating, don't miss any details. At the same time, I need you to help me contact a psychology expert, who may be able to find a breakthrough from You Ran's psychological state."
After a night of hard work, Situ Han finally found a psychology expert with profound attainments in consciousness research in modern S City.
Psychology expert (carefully reviewing Xu Youran's case): "This situation is extremely rare, but not impossible. She may have experienced a special psychological phenomenon called 'parallel reality perception', which means that under extreme conditions, consciousness can briefly connect to another parallel time and space or memory fragment."
Situ Han (shocked): "How...how is this possible?"
Psychology expert (smiling): "Science always goes beyond our imagination. I suggest that Xu Youran receive more in-depth psychological treatment. At the same time, we can also try to guide her to 'enter' that time and space again while she is conscious. Perhaps we can find more clues."
Just as Situ Han was discussing the treatment plan with the psychology expert, a strange sound suddenly rang out in Xu Youran's ward. The sound seemed to come from another time and space.
Xu Youran (pale, clutching the bed sheet tightly): "Listen...listen, that voice is coming again...he is looking for me!"
Situ Han (quickly stepped forward and held Xu Youran's hand): "Don't be afraid, I'm here. No matter where you are, I will find you."
As the voice disappeared, Xu Youran fell into coma again, but there was more firmness and determination in her eyes.
When Xu Youran woke up again, it was already late at night, with only a soft night light on in the ward. Her eyes were no longer confused, but flashing with unprecedented determination.
Xu Youran (softly but firmly): "Situ Han, I know I have to go back there again, not to escape, but to find the truth."
Situ Han stood aside and looked at Xu Youran's eyes. He felt unprecedented pressure, but at the same time he was also moved by her tenacity.
Situ Han (sighed, and finally chose to support): "Okay, but this time, I will accompany you. Whether it is a dream or reality, we have to face it together."
Under the guidance of a psychology expert, Situ Han and Xu Youran began a series of preparations. They tried to use meditation, deep relaxation and other techniques to guide Xu Youran to "enter" the S city in the Republic of China while she was conscious.
As her breathing gradually stabilized, Xu Youran began to see a blurry picture in front of her eyes. It was a familiar street and a familiar crowd. This time, she was no longer a bystander, but a participant.
Xu Youran (looking around and speaking to Situ Han, even though he’s not actually here): “Look, here we are. This time, I’ll be more careful and not miss any clues.”
Situ Han (in modern times, inferring the situation through Xu Youran's reaction): "Youran, stay calm. Remember, we are here. You are not alone."
Relying on her previous memories, Xu Youran led the "virtual" Situ Han to the mysterious mansion again. This time, they searched every corner more carefully and finally found a dusty diary in a secret cellar.
Xu Youran (excitedly reading out the words in the diary): "...the secret that the Yun family has guarded for generations is not gold or silver treasures, but a strange substance that can affect people's consciousness..."
As the diary was revealed, Xu Youran finally understood why she traveled between these two time periods. It turned out that the strange substance not only existed in the Republic of China, but also had a connection with the modern world under some unknown force, affecting her consciousness.
Situ Han (sharing this discovery with a team of experts via video link in modern times): "It seems that we have found the key to solving all the mysteries. Next, we need to find this substance and study how to eliminate its effect on You Ran."
Just as everyone was immersed in the joy of discovery, Xu Youran in the ward suddenly closed her eyes again, as if she was summoned by that time and space again.
Xu Youran (whispering, as if foreshadowing the upcoming adventure): "It's not over yet... There are more truths waiting for us to discover."
As the words fell, Xu Youran's breath became stable again, as if everything had returned to the starting point. But Situ Han knew that this was just a new beginning. They were about to embark on a more dangerous and complicated journey to uncover the secrets hidden deep in history.
