As mentioned earlier, the Hidden Assassination Squad exists for special missions, however, not just anyone can join the Hidden Assassination Squad. For instance, only-children can't join, people with spouses or children can't join, and those with elderly to care for can't join. Moreover, there's a psychological survey before entering, and regular psychological checks afterwards.
It's easy to imagine that the tasks undertaken by the Yanhuang Soul members are mostly quite dangerous, let alone those of the Hidden Assassination Squad.
So generally, Fan Lingtian wouldn't easily deploy the Hidden Assassination Squad unless there's a special request from above. Since the establishment of the Hidden Assassination Squad, eight members have committed suicide due to pressure or nightmares. Although this doesn't seem like much, their mental health has always been under severe tests.
