Director Liu Jiang, winner of various awards including Best Director at the 28th China TV Drama Flying Awards, revealed that the series was produced with guidance from the Ministry of Public Security, with many pivotal scenes rooted in real-life cases, such as a tense security inspection at a nuclear power plant.

Packed with high-tech espionage tactics — remote data theft, covert surveillance, and more — the show highlights the increasingly sophisticated and hidden nature of modern spycraft, shared Liu, who hopes the drama will honor the unsung heroes who work tirelessly to protect national security.
