After the "Great Awakening" event, the alien beasts from the Classic of Mountains and Seas reappeared in the world, causing the collapse of civilization. In order to find the legendary "Jianmu" that can purify the influence of alien beasts, a young "remnant" scavenger who relies on the fragments of the ancestral "Mountain and Sea Map" to survive in the ruins must cooperate with a "Tiansuan" engineer who is obsessed with using technology to restore myths, and travel through the dangerous land reshaped by alien beasts. At the same time, he must avoid an emerging sect that regards alien beasts as gods and hunts them.
