Yean Middle School has a history of nearly a hundred years. No matter how the times change, it has always stood in the center of Yongnam City and watched the passage of time. The main building on the small campus still maintains the quaint architectural color of a century ago, which is particularly conspicuous in this campus that has been renovated several times. Everyone in the school knows the "secret" of the main building - an underground staircase that leads to nowhere. Every student, teacher, security guard and even the principal who entered this school had tried to go down to the bottom of the stairs to find out out of curiosity, but the dark atmosphere dissuaded waves of "explorers" after just a few turns. It wasn't until 2000 that a student accidentally fell down the stairs and caused an accident. The leaders at that time installed an iron door at the entrance of the stairs to prevent people from entering. But legends about the stairs have always spread. Everyone is not shy about talking about the stairs in the main building of Li'an Middle School in any place. Some people say that the stairs go as deep as the 10th floor of the main building, which was once a research institute for the Japanese army during World War II. On the contrary, the legend is that the 10th floor was a shelter built by the Kuomintang during World War II. Some students claimed to have seen groups of weasels entering the stairs. In short, the legends about the staircase are numerous and unfounded. One day, a legend came to Chen Xiaoyu's ears: "There are 66 floors of stairs, and there is a tomb at the bottom." When Chen Xiaoyu heard this, his headache almost killed him, and his twitching temples seemed to be hinting at something. From then on, every time Chen Xiaoyu saw the main building, he seemed to hear a voice telling him to go down, "Want to go down and take a look? Well, I have to find a chance to go down..."
Concept: The story originated from two dreams. The two dreams on different days merged inexplicably. The awakening in the second dream made me feel scared. I couldn't even tell the dream from the reality. There were only endless stairs and disasters.
