Seven Day Rule

My name is Lu Chen, an ordinary office worker. Until one Monday, my phone received a text message without a sender—— "Rule for this week: Don't stay in any location for more than twenty-three minutes." That morning, the subway I took was delayed. The moment the stay lasted for more than twenty-three minutes, all the passengers with their heads lowered in the carriage raised their faces at the same time - their eye sockets were empty. From now on, I will receive a new rule on my phone every Monday. "Don't respond to anyone who calls you by your full name." "Don't look in the mirror after dark." "Don't try to find the source of the rules." Behind every rule is the password for a strange event. I relied on these rules to avoid danger and became a "lucky person" in the eyes of others. Until one day, I decided to track down the sender. That number belonged to a man who died ten years ago. His name is Lu Chen.
