I highly recommend this book. What makes this book different from other novels is that it is true. The story tells the story of a folklore professor who took five of his students to the Yinshan Mountains for inspection. As a result, they fell into the trap of another civilization and had to face various irresistible and strange dilemmas. The strange things inside, and the disappeared sects written in it, such as Meishan Sect, Lushan Sect, Pu'an Sect and Maoshan Sect, are all real. The Three Emperors Sect was one of the three major talismans of Taoism. Some of the methods written about how to deal with strange things are simple methods that ordinary people can use. The protagonist Jiang Yi's character and growth line are clear throughout the book. The story is interesting, the characters are not stupid, and the world view is grand. Regarding the disappeared ancient civilization continent, a lot of remaining data has been found to support its existence. It is not written out of thin air, especially the overlap of the worlds being read, the confrontation between two different lives, the common memory about God, and what is the true practice? These are all well-documented and really, really nice to look at.
