Mountain and River Password

During the Wanli period of the Ming Dynasty, the world was about to fall. Scholar Xu Hongzu broke free from the prison of the imperial examination and vowed to measure thousands of miles of mountains and rivers with his feet. However, he soon discovers that this land hides secrets that transcend time. The rainbow in Tiantai Mountain lasts for three days, the phantom of the monster from "The Classic of Mountains and Seas" appears on the moonlit night at Yandang Peak, and the secluded pool in Huangshan reflects the starry sky that does not belong to this world - these are not miracles, but the last cry for help from an ancient system that is on the verge of collapse. Xu Xiake was forced into a secret war concerning the survival of civilization. On one side are the imperial eagle dogs and the mysterious organization who intend to control the "dragon vein power"; on the other side are lonely travelers like him who have inadvertently touched the truth. The travel notes in his hand gradually changed from landscape notes to a code book for deciphering the ancient "planetary adjustment network". The Classic of Mountains and Seas is an encrypted engineering log, and the myth is the prehistoric truth of amnesia. When the countdown of the vein system comes to an end, this scholar with only his feet and pen and paper must find the twelve keys scattered around the world before everything collapses, and face a cruel and gentle truth of the universe: human beings are not the masters of the world, but children placed in the "cradle" by higher civilizations. Now, the cradle is about to tip, and the mission of the guardian unexpectedly falls on the shoulders of a mortal. This is an expedition against time, an ultimate inquiry into the meaning of civilization.
