After the disaster known as "Skyfall", the glorious interstellar civilization turned into dust, leaving only cold steel ruins on the planet and "deep space relics" buried deep underground. Newly born humans built city-states on the ruins and struggled to survive. Jiang Che, a ruin hunter, relies on his talent in interpreting data from the old era to explore the truth behind the collapse of previous civilizations. Lin Wan, the guardian of order from the central tower, was ordered to recover all out-of-control "relics" and maintain the fragile balance of the new world.
An unexpected relic excavation brings the fate of two people with completely different identities and positions together. They discovered that the disaster that destroyed the old world was not far away. An invisible force was awakening deep in the relics, trying to drag the new civilization into the abyss. In order to survive, and for the beliefs they each protect, they have to join forces and embark on a journey to uncover the mystery of the end of the era and fight against unknown horrors.
