At an archaeological site in the northwest desert, Ji Heng accidentally got caught in the quicksand and traveled to the ancient world of mountains and seas with a mysterious bronze. This is not an illusion, but the true appearance of the earth's distant past: alien beasts are strange beings evolved from the environment, and gods are tribal leaders who master high-dimensional energy. Ji Heng uses the logic of modern science to survey mountains and rivers and deconstruct myths step by step, from the mystery of the inability to cross weak waters to Kunlun's plateau technology, from Jingwei's sea reclamation elegies to Dayu's flood control projects. He records, compares, and verifies, and connects the scattered "Book of Mountains and Seas" into a vivid history of mutual support between ancient and modern times.
