Shen Gui, an archaeologist in the past, is now a tomb walker. He is not looking for treasure or fame, he is just looking for the mystery left behind by his father - a fragment of a book that records the traces of monsters. Under the moonlight in the ancient tomb, the moss is like skin, and unnameable creatures are lurking in the cracks between the stones. Shen Gui uses the lamp of reason to illuminate the unknown night, but every time he digs, the boundary between reality and fantasy is torn apart: deep in the ancient tomb, the boundaries between monsters and humans are blurred, and the truth about his father lingers in the traces of monsters. The story uses Shen Gui's obsession with his father's love as a clue, and weaves the strange ecology of monsters, the secret mechanisms of the tomb, and the bizarre legend of the symbiosis between humans and monsters into a confusing elegy. The core conflict is: Can Shen Gui preserve his true heart between the monster's temptation and his own reason, and uncover the dust-laden family relationship and truth? This is a tomb-robbing journey about monsters, memory and redemption, as well as a dark fairy tale of self-reinvention.
