In this quiet university campus, everything seems normal. The old building of the library looks warm and quiet under the reflection of the setting sun. Students are in groups of twos and threes, discussing on the lawn or busy reviewing in the coffee shop. But beneath this calm exterior lies a disturbing story.
Lin Yuqing is a junior student in the Department of Management. She has a gentle personality and excellent academic performance. She often uses her spare time to search for books that interest her in the library, and is used to swimming in the sea of books. On this day, she came to the library as usual, but when she was checking information, she heard whispers in her ears.
"Have you heard? Zhang Wei is missing!" Xu Ting, who is in the same class, said to her roommate nervously.
"Wasn't he still there last week? Why did he suddenly disappear?" Another girl asked in surprise.
Lin Yuqing's heart was lifted instantly. She was not close to Zhang Wei, but she could always see him on campus. Zhang Wei is an excellent student with a cheerful personality and has participated in many on-campus activities. How could it not be shocking to suddenly disappear now?
"I heard that he was last seen in the library. He seemed to be looking for some important information." Xu Ting continued, with an uneasy look in her eyes.
"But, why didn't anyone see him leave?" Lin Yuqing felt uneasy and had a vague premonition. She quickly recalled her recent contact with Zhang Wei, and his smile at that time emerged in her mind.
Rumors about the "Rules Club" began to circulate on campus. It was a mysterious club. Many students said that they would perform some kind of ritual, and those participants would perform some kind of ritual during the ceremony.
