Introduction to the Cave Illusion: The Lion Cave is the most famous place in the underground forest. There is a huge rock in the cave with "癓石" written on it. This cave, with a total length of 70 meters, goes up the stone steps and out through the cave. At the other exit is a purple linden tree, which is called the welcoming tree or the peacock tree. At the entrance of the Lion Cave, clusters of strange-shaped ferns grow proudly on the cliff. This is called volcano flower, and the fruit it bears is called volcano fruit. I heard it has special effects in treating many diseases.
