The docks of Mingwang City also function as the third-largest port in the nation—Keppler Port,
which is significantly different from a conventional port,
with sea voyages for tourism constituting only a small portion.
The port mainly serves to receive cargo logistics from countries around the world, as well as those 'World Immigrants' who have been approved.
Every year, numerous immigrants from various countries come here, completing their registration, inspection, and subsequent urban and work arrangements in Mingwang City.
As Luo Di and his companions passed the port's checkpoint on the travel agency's coach, they saw many buses marked with immigration signs driving out from the inner part of the port.
Sea outings are also restricted,
with the furthest distance not exceeding the "Roof"*, a massive structure built decades ago with the collective efforts of all humanity to blockade the country.
*The Roof project is introduced in the historical timeline.
