As Jack and Emily continued to delve deeper into the abandoned hospital, their flashlight beams swinging through the dark corridors, casting long shadows. As they advanced, an indescribable feeling gradually overcame them, as if they were not the only living beings in this hospital.

They arrived at a closed operating room. The lock on the door was rusty, but Jack easily pried it open with a piece of iron. The room was dim, with only a dim operating light flickering faintly. Emily held Jack's hand tightly, and he could feel her trembling.

The operating table was covered in dust, looking like it hadn't been used in ages. But in the center of the table lay an open surgical journal, its pages covered in strange symbols and indecipherable text. Jack took a closer look and saw that the symbols seemed to describe an ancient surgical ritual, while the text was in a language he had never encountered before.

As they studied the log, Emily suddenly felt someone watching her. She looked up and saw a pair of eyes gleaming faintly in the darkness in a dark corner at the other end of the operating room. Her heartbeat quickened, but when she pointed to the corner, the eyes disappeared.

Jack reassured her that it might just be the light and shadows playing tricks on her eyes, but they both knew that this hospital held a dark secret, and they might have touched upon its core.

They decided to continue exploring, hoping to find more clues about this forbidden surgery. As they went deeper, more strange phenomena began to occur. The lights in the hallway suddenly flickered on and off, the temperature in the operating room fluctuated between hot and cold, and sometimes they even heard low whispers.

Finally, they found a hidden room with a door engraved with ancient symbols that matched the ones in the surgical log. They pushed the door open and saw a strange device operating in the dim light of the room, emitting a faint blue light.

As they watched in astonishment, the center of the device suddenly opened, revealing a sealed corpse whose eyes were still moving. Jack and Emily were speechless at the horrific sight, realizing that this forbidden operation had not stopped with the doctor's death, but was still continuing.

They don't know who the body is or what the purpose of the operation is, but they know they must stop it. They begin looking for a way to shut down the device, hoping to stop this horrific experiment.

However, when they try to leave the room, the door is unexpectedly locked, and they begin to panic, thinking that the room is a closed trap from which they may never escape.

In the darkness, those eyes are still watching them, as if waiting for something. Jack and Emily know that they must solve the mystery in order to find hope of survival. Their time is running out, because in this long-abandoned old hospital, death may come at any time.

Jack and Emily are in a closed room, anxiously looking for a way to escape. They realize that the design of this room is a trap to protect the secret of the forbidden surgical experiment.

The device in the room continued to operate, and the corpse's eyes continued to move, which made the two men feel extremely scared. They knew that if they could not stop the device, they might become the next experimental subjects.

They began to carefully observe the room, hoping to find some useful clues. Eventually, their attention was drawn to a strange pattern on the wall. The pattern looked like a mechanism, consisting of several rotating discs, each engraved with a different symbol.

Jack and Emily decided to try the mechanism, hoping to find a way to disable it. They compared the symbols in the surgical log with those on the device and eventually found the correct combination.

When they turned the disc and the symbols matched, the room suddenly made a loud noise and a hidden passage appeared on the wall. They rushed into the passage without hesitation and found themselves in the basement of the hospital.

The basement was filled with darkness and dampness, but they had no time to pay attention to these things. They knew that they had to leave this horrible place as soon as possible.

As they searched for an exit in the basement, they encountered many terrifying creatures. These creatures seemed to be the product of that forbidden surgical experiment. They were ferocious and abnormal, making their escape extremely difficult.

However, Jack and Emily did not give up. With courage and wisdom, they continued to fight these creatures and finally found the exit of the basement.

They escaped from the basement and came to the outside of the hospital. Although it was still a rainy night outside, they knew that they had escaped from that horrible nightmare.

They gasped at the hospital entrance, looking at the city lights in the distance, feeling extremely lucky. They knew that they might always remember the horror of the abandoned hospital, but at least they survived.

However, they are not completely out of danger. They realize that the forbidden surgical experiment may still be going on, and they must make this secret public to ensure that no one is threatened again.

Jack and Emily decided to write about their experience and report it to the police, knowing it might be the only thing they could do to prevent the crazy experiment from happening again.

On this stormy night, they left the long-abandoned hospital, carrying a huge secret and embarking on a new journey. Their lives may never return to the past, but they know that they must move forward, for themselves and others, to prevent those eyes in the darkness from appearing again.
