I Picked up a Name from the Ruins

"Ruins" swallowed up most of the world. No one knows where they come from, only that only one out of ten people enter. People who came out of the ruins couldn't tell what they saw. Lin Du is the youngest S-class agent in the Ruins Department. During an illegal rescue, he came across a ruined monument of unknown age deep in the ruins. The ancient characters on the stele lit up the moment he touched it, and there was something new in his consciousness. A system called [Xuhen]. The first message the system gave him was: "Don't trust anyone."
