The legend of Changbai mountain
Legend has it that there are still ancient beasts living in Tianchi Lake in Changbai Mountain, and Tianchi Lake is submerged by Tianshui. The Qing Dynasty's "Changbai Mountain Jianggang Zhi" describes: "Since Tianchi, a monster has surfaced, with a golden head as big as a basin, a horn at the top, and how long it is. The hunter thought it was a dragon. " Over the years, Changbai Mountain has become more and more famous, and scientists from all over the world are scrambling to come to Changbai Mountain to carry out research. They found that Tianchi is an alpine lake formed by volcanic eruption, surrounded by 16 peaks, where the vegetation is barren and the natural environment is sinister. Strangely, there are very few organic matter and plankton in alpine lakes, but scientists keep discovering the existence of life in Chengcha River. How did these creatures survive in a cold and sinister environment and evolve to the top of the biological chain? This is really puzzling, and even scientists have no answer.
