The underground water system in Liantang Town is well-developed, with many underground streams emerging from the mountain valleys near Liantang Town and converging into creeks on the surface.
Feng Yuan and his companions are headed to one of the more unique underground river exits, located within the mountain. The entrance cave is quite low, so it's typically better to enter in summer; however, during summer, the water level rises, completely submerging the entrance in water.
Even now, to get inside, they must lie on a small boat and rely on Spirit Beasts to push the boat through the entrance without getting wet.
Upon learning this, the Fluffy Fire Wolfhound decisively decided to wait until Feng Yuan reached the destination before releasing it. Until then, it hid in Kong Qing's space with Big Cat and the others.
