The Rule Whisperer

The day Wen Shi was laid off from his job at a big company, his sister Wen Zhi had already been missing for three months. Her last message was only six words: "Brother, don't look for me. The rules will eat you." To find her, Wen Shi accidentally entered the boundary of the S-class horror tale "City of Lies" and was marked by the system, leaving him only 24 hours to live. The system issued its first task: "Midnight Convenience Store." The surface rule: You must not say 'Welcome' to the third customer. The real rule: You must say 'Welcome' to the third customer. Wen Shi followed the real rule and was almost dragged into a black hole under the cash register. In panic, he noticed a scratched-out photo in the employee roster with half a line of writing below: "My name is Su Wan, please call my name." He called out that name, and the female ghost dissipated. After a three-second delay, the system prompted: "Warning: Rule tampering detected. This task's difficulty has been revised from D-level to B-level. Someone is watching you." His phone rang. An unknown number sent a photo—Wen Zhi locked in a room full of mirrors. The caption: "Wen Shi, welcome to the Horror Tales Department. Want to find your sister? Survive the first week first." From that day on, Wen Shi became a temporary worker in the Horror Tales Department. Others enter horror tales relying on courage; he enters relying on rules. But no one told him that rules can lie. Real rules can also lie. And he is the only one who can make rules tell the truth. — Description from novelcodex.org
