Seven Points Eight: the Stonespeaker and the Earth Constant

On the banks of the Yakeshi Zadun River in Hulunbuir, I have been alone for thirty years. He touched the cracks in the stone, listened to the frequency of the stone, and calculated a constant - 7.8. The ratio of the impactor's bounce distance to its characteristic length can be verified by anyone. This is not civilian imagination, this is stones don't lie. Then he read "The Classic of Mountains and Seas" using this method. Kunlun is the Qinghai-Tibet Plateau, and Buzhou Mountain is the Hengduan Mountains. That is not a myth, it is a letter left by survivors to the future. Two lines: the growth of a folk explorer and the birth of a scientific hypothesis. This is not popular science (the hypothesis has not been verified), it is not science fiction (the content is real), and it is not autobiography (scientific exploration is the main line). It belongs to a new category—exploratory nonfiction. Stand honestly between the known and the unknown, write down the process, and judge for yourself. The Zadun River is still flowing. The keys have been handed over. Now, it's your turn.
