Ye Xuanyi, an ordinary young man, discovered that the modern city he lived in was actually a false prison woven by indescribable beings. He gained extraordinary perception by taking potions, and was promoted to Sequence 9: Observation Apprentice, allowing him to glimpse the horrific truth beneath the surface of the world: many "residents" were actually man-eating monsters disguised as humans.
During the exploration, Ye Xuanyi met several other awakened people, and they formed an alliance to find a way to escape together. After going through hardships, they found clues to escape, but the price was cruel - at least four awakened people were required to voluntarily sacrifice all their energy to activate the teleportation array. In the end, the partners chose to sacrifice and turned into stars, sending Ye Xuanyi to the "reality".
Ye Xuanyi successfully escaped, but found that he had stepped into a world with strange rules. Holding the token left by his companions, carrying a heavy past and the will to sacrifice, he is determined to survive in this dangerous new world, become stronger, and uncover the ultimate mystery behind the indescribable existence.
