Jack and his friends are a group of young people who love adventure. They heard about a long-abandoned old hospital, where a forbidden surgical experiment is said to be hidden. Curiosity drives them to explore the inside of it.

That night, under a dark and windy sky, Jack and his companions arrived at this eerie hospital. The hospital door stood open, inviting them in. They cautiously stepped inside, feeling the chilling atmosphere that permeated the air.

The lights in the first-floor corridor flickered, as if they would go out at any moment. They followed the flickering lights and arrived at a closed operating room. The door was half open, and a cold wind blew from inside. They couldn't help but shiver.

Jack and the others mustered up their courage and entered the operating room. The operating table was covered in dust, clearly unused for a long time. However, when they looked closely at the table, they found a body wrapped in plastic wrap. A note covered the body, which read: "Taboo Experiment, Do Not Touch."

They couldn't help but feel fear, but curiosity made them decide to continue their exploration. They climbed the stairs to the second floor and found that the corridor on the second floor was covered with mysterious symbols and images. These symbols and images made them feel uneasy, but they continued to move forward.

They arrived at a closed room, the air filled with a strange atmosphere. In the center of the room stood a table, upon which lay an ancient book. On the cover of the book was written: "The Mystery of Forbidden Techniques."

Jack and the others couldn't help but open the book, which revealed a record of the forbidden surgical experiments once conducted at the hospital. It turned out that the hospital had once conducted a mysterious surgical experiment, attempting to cure a disease through forbidden techniques. However, the experiment failed, and all the patients who participated died. Since then, the hospital has been abandoned and has become a haunted place.

They realized they had triggered a taboo, and the hospital's terrifying phenomena began to emerge one by one. The lights flickered, blood appeared on the walls, and eerie noises came from the floor. They were panicked and wanted nothing more than to leave this terrifying place as quickly as possible.

However, when they tried to leave, they found the hospital door closed. They fell into despair and could only spend endless nights in this horrible hospital. And everything they experienced became a nightmare forever in their lives.

From then on, the abandoned hospital became a forbidden area, and no one dared to set foot there again. Jack and his companions paid a heavy price for this expedition, and their story became a supernatural legend that circulated throughout the city.

Jack and his friends experienced countless horrors in the hospital and realized that if they didn't find a way to escape as soon as possible, they would never be able to leave this hellish place.

They decided to go back to the first floor and look for a possible exit. In the hallway, they found a door with a sign on it that said "Exit". However, when they tried to push the door open, they found it was locked.

They began searching for the key, only to find a mysterious room in the basement of the hospital. Inside the room was a table and a chair, with an ancient book on the table. Jack opened the book and discovered that it contained the history of the hospital and the forbidden surgical experiment.

It turns out that the hospital once conducted a mysterious surgical experiment, attempting to cure a disease through forbidden techniques. However, the experiment failed, and all the patients who participated died. Since then, the hospital has been abandoned and has become a haunted place.

They realize that there is an evil force hidden in this hospital, which craves more lives to fill its greed. They must find a way to stop the spread of this force in order to escape this nightmare.

In the corner of the basement, they discovered a mysterious altar. On the altar stood an ancient statue that exuded an evil aura. They speculated that the statue might be the key to the forbidden experiment.

They decided to destroy the statue in the hope of stopping the spread of evil. In the process of destroying the statue, they experienced unprecedented horror. However, they did not give up, but continued to move forward with determination.

Eventually, they succeeded in destroying the statue, the evil force was suppressed, the horror phenomenon in the hospital gradually disappeared, and they finally found a way to leave the hospital.

Jack and his friends fled the long-abandoned old hospital and vowed never to return again. However, they knew in their hearts that this nightmare would remain in their memories forever.
