The Old Task Force deliberately took a detour, crossed the Red River from elsewhere, and returned to First City from the southeast. This was because they were afraid that the advance base camp's garrison would report the fact that they had many military exoskeletons. When the time came, even their acquaintances wouldn't help them and might even add to their troubles.
Compared to the North Shore entrance, there were a large number of manors southeast of First City. Many citizens came and went every day, so the inspection wasn't that strict. In addition, the matter of capturing the colosseum assassination's accomplices had been going on for many days. The soldiers were definitely not putting in as much effort as before.
