Unlike patrol camps and other inspection agencies "affiliated" with the Government Office, the Security Office is a secret agency directly under the Wang family. Its key personnel are primarily composed of clan members from the Wang family or trusted household members who have served the family for generations.
The most critical role of the "Security Office" is counter-espionage, while also monitoring activities within the Wang family's sphere of influence, particularly the areas surrounding Ping'an Town and neighboring towns, to prevent certain "idle big shots" from trespassing onto their territory unknowingly.
In the early days of establishing the Security Office, the ladies from the Group Immortal Palace contributed significantly, offering its staff several hands-on practical lessons that were both lively and groundbreaking. The current level of proficiency within the Security Office can largely be credited to Wang Mei's "remarkable achievements."
