The D618 Star Regulatory and Investigation Department was located in the planet's central region, a considerable distance from Xingluo Bay, the residential area in Zone D where Ning Xuan lived.
Chen Nan and Ning Xuan took an auto-piloted Flying Car to the central region. The Regulatory and Investigation Department was responsible for regional security and possessed law enforcement authority.
Ning Xuan's house was equipped with a security system. Although it wasn't a high Level, the system was monitored by the regulatory department. In theory, if the system were breached, it should have automatically sent an alarm to the department.
But last night, an assassin had clearly broken in, yet the security system hadn't reacted at all. Ultimately, the D-level security system was just too low-grade.
