The director is their direct superior, who controls their fate, and must not be offended.
Just like Liu Huang, who offended the director—boom, ten years later in the plot, he went from being a high and mighty Traitor Leader to a death-row prisoner, and then he was sealed in wax, a clear testimony to this fact.
Heaven is unfair; some people come in as directors, or even as higher-level figures.
But most people can only start as extras, struggling step by step from the bottom, with their lives constantly at risk.
Isn't the real world just the same?
Some are born into families that send them abroad on public funds, while others casually alter their school and identity records through their parents' connections.
Others are born with a golden key and set a "small" goal like making a billion.
But most people are born into poverty, spending over a decade in bitter study, only to still work at the bottom of society, struggling just to earn a living.
