After making preparations, the group was ready to head for Helros. They arrived at the airport with the pass mark given to them by the headquarters before departure for inspection.
The High-peak people's security check system was learned from Earth. Since the end of the Otherworld War, Ronisca had become a relatively open country, attracting countless visits from outsiders. Hence, they adopted the security check system from Earth to ensure airship safety.
Of course, after nearly thirty years of development, their security check system had somewhat deteriorated, or else the Advance Team and the Zhuyan People wouldn't have been allowed on the airship at the same time. It's believed that after the investigation of this matter is completed, the High-peak people would surely reform their related systems.
However, all of this was irrelevant to the Advance Team. Their current mission was to infiltrate Helros, complete the task assigned by the Headquarters, and then return safely.
