Wild Wolf Valley was only about 70 km west of Blackhot City. If they brought nothing with them, it would not be difficult for Zhang Tie and the other students of Seventh National Male Middle School to arrive there during the day, although they would have to expend some effort. However, as each of them was carrying tens of kilograms of luggage on their backs, it was undoubtedly a huge struggle for everyone.
The scenery outside the city walls was completely different from that within the walls. Within the areas 10km away from the city walls, they were able to see patches of farmlands and the farmers working in the fields. There were watchtowers set at a specific distance between each other. These watchtowers had two functions: the first function was to send warnings, and the second function was to provide refuge for the farmers in the event that they suffer an attack from any dangerous living beings at any point in time.
