The young man fell into a deep dream for ten years. After waking up, his spiritual energy revived.

At the same time, evil spirits appear in the world, and the creatures in "The Classic of Mountains and Seas" wake up one by one. Is everything a man-made or natural disaster? Is it the interpretation of a big dream or a new dream?
