Even though Chang Lin Town was surrounded by mountains on three sides, there were two roads into the town. One of them was the bigger road. It extended from the nearest city, Bronze Mound. The smaller road was the one that Feng Bujue's group appeared on at the start of the scenario.
The situation on the bigger road was far more urgent. The current Bronze Mound was filled with people from various schools, characters from the martial world, and even people from the government. There were roughly several thousands people. Naturally, not all of them were going to Chang Lin because the small town wouldn't have fitted all of them anyway. So there were conditions to be fulfilled to get to Chang Lin Town through the big road.
