Deadly Reminder Cantonese

Guo Baifei, Jiang Xiwen, and Liu Li had a deep bond with Superintendent Luo Youbang and his four apprentices when they first entered the academic world over a decade ago. Three years ago, during an operation, Bang was shot dead by bandits, and Li was critically injured and fell into a coma; Wen blamed Fei for this, and from that point, the friends parted ways. A dismemberment murder case involving a young woman arose in the city, and the victim was linked to a human trafficking group. Wen, belonging to the intelligence division, was responsible for investigating the group's crimes, while Fei from the major crimes unit was tasked with tracking down the murderer, dispatching trainee inspector Wen Jiali to infiltrate the criminal group. Fei and Wen coincidentally received mysterious text messages suggesting clues about the case, prompting their superiors to merge both teams and establish the Mysterious Information Intelligence Bureau (ASIB). Led by Fei and Wen, the ASIB worked together to decipher these seemingly futuristic messages to solve the bizarre murder case. The messages were enigmatic and could not be explained scientifically. Who was sending these messages? A person from the future? Or an unknown natural force? Was the sender a friend or foe?
