[Dark Side]
Han Dong was not surprised by this information at all.
He himself had an underground construction in his mansion, let alone the Holy City.
From many detailed pieces of information, Han Dong could guess the existence of the Dark Side.
After all, in such a world structure, the internal stability of the Holy City must be absolutely ensured... Many troublesome matters need to be quickly dealt with in secret.
Moreover, there are agents from outside the city within the Holy City, and the top leadership is well aware of it.
And so, channels other than open ones need to be pursued, the Dark Side should be in charge of the investigation.
What Han Dong didn't expect was the existence in the Dark Side of a 'school institution' similar to the National Royal Academy of Knights... specially training unique talents to operate in secret.
Mr. Black White's reminder suggests that the students below will have special traits and will not be easy to deal with.
