"What a king, there is no leaderless lady who does not come, the mountains do not boil firewood, boil the liver and lungs, dig wells and cut salt, ask ghosts to beg for money, and the birds are vertical and horizontal, and if you want to visit the earth fairy in a hundred steps and nine times, you will find the black sheep first" This proverb of the earth fairy villagers is like a bright light, leading Professor Sun and Hu Bayi and others to approach the mysterious earth fairy tomb step by step. The old proverb that circulates from the mouths of the villagers seems to hide a secret clue to the ancient tomb. In the process of exploration, they will not only have to face complex terrain and steep roads, but also solve a series of puzzles to uncover the secrets behind the ancient tomb of the Earth Immortals.
