Interstellar Archeology: the X-Files

On the inside of the Liangzhu jade cong, there is a set of micro-engraved symbols that have been ignored by the authorities. Zhang Dinglun has been studying it for ten years, but no one takes it seriously. Until one day, two mysterious people came to his door and showed him a photo—— In the alien ruins from 170,000 years ago, there is a metal door engraved with symbols. Those symbols are exactly the same as the Liangzhu jade cong he studied. Three days later, he boarded a spacecraft bound for Haumea. He thought he was going to explore the unknown. Until those eyes in the dream appeared in front of him again: "You're finally here."
