Su Mo finished his shopping and didn't linger in the black market, preparing to head home.
The Rusted Wall Level has inspection equipment, and the Hawkeye drone he bought came from the Public Security Bureau, so it obviously couldn't be brought in directly.
However, entering the Inner City from the outskirts doesn't necessarily require going through the Rusted Wall.
As mentioned before, New Moon City has an incredibly vast sewage network.
This complex system runs through both the outskirts and the Inner City. As long as one is familiar with its structure and finds a way to avoid the Public Security Bureau's underground patrols, it's entirely possible to "smuggle" into the Inner City.
Those criminals without citizen status who can travel between the outskirts and the Inner City almost always use the sewers.
To navigate the sewers easily requires extensive experience.
Of course, for Su Mo, who has a map in his head, this is no big deal.
