Entry and exit to Free State are extremely strict, even for members of the Four Great Families, each time requiring verification of identity information and a pass.
Permanent passes are jointly issued by the Holy Light Tribunal and the heads of the Four Great Families in Free State, only available to foreigners who have made significant contributions to the Free State.
There's only one quota a year.
Nian Yunxi naturally knew that Zhu Ruowan had a temporary pass; otherwise, she wouldn't even be able to enter any of the four entrances to Free State, let alone the Intercontinental Research Institute.
Breaking in would only meet with the merciless gunfire of the Cavalry.
She was merely trying to use her influence to pressurize others.
Her significance to the Intercontinental Research Institute was immense, very likely able to completely change the entire cell theory and the research on various genetic viruses in the future.
