In the Age of Ending Dharma, the world undergoes changes, and the exhaustion of spiritual energy leads to the collapse of the cultivation system. Ancient technological relics that have been sleeping for thousands of years unexpectedly awaken, and a torrent of machines and alienated beasts sweep across the world. Loose cultivator Ye Zhao awakened the "Star Map Navigation System" while on the run, which can analyze technology/cultivation information, mark danger and resource points, and can also integrate ancient methods and future technology to create a new evolutionary path. From surviving in the wilderness to building the last bastion of mankind, he not only has to lead the survivors to fight against alien beasts and mechanical legions, but also uncover the truth about the self-destruction of ancient civilizations due to "star core overload", and finally use the star map as the key to restart the reincarnation of civilization in the "Countdown to the End".
