After his interest in the airship faded during the first two days of flight, the following days gradually became boring. Even above Blackson Human Clan Corridor, Zhang Tie still could not easily see human cities through the porthole.
When he looked down through the porthole of the airship he saw many of the same scenes. Continuous hills, rippling ranges, grasslands and endless forests. Everywhere he experienced was deserted and sparsely populated. He could not even see big towns or villages, let alone cities. After all, compared to the area of the whole Blackson Human Clan Corridor, the population here was too small. Due to people gathering in the cities in order to be protected by city walls, the chance to see a large-scaled human settlement outside of city walls would be very low.
