The underground cave was a very large map. The tunnels crisscrossed and were interconnected. The players could encounter many events. There were three entrances to this place, and they were separately hidden all over Chang Lin Town. No matter which entrance the players took, there was only one way to move forward, and they were sure to encounter some kind of trap or monster. The routes would turn numerous, and various rewards were hidden in the middle or at the end of these routes.
