Li Ang walked a distance and understood what was meant by "underlayer".
In the dark passage, there were some iron windows for ventilation, through which one could see the city's sewers. But if you were inside the sewers, it would be difficult to find these iron windows, and even if you did, you couldn't navigate the crooked gaps to enter this dark passage.
According to the system's miniature map, he was now beneath Spark Port.
The city's underlayer was just a large secret passage with many exits; the real emphasis was on the exits of these passages.
He reached another exit, climbed the stairs, opened the mechanism, and found it was a cellar.
All around were ice blocks, and the goods placed there were related to sugar, oil, and milk. By checking the labels and map location, he deduced this must be the cellar of the dessert shop he had eaten at before.
Does this shop know there's a secret passage beneath their property?
