Three years ago, Lu Li's hometown collapsed before his eyes, and he was publicly humiliated and became the laughing stock of the entire city. Three years later, he dug out a broken copper plate in the interstellar ruins, and the system popped up: "Sign in successfully, get ancient memory fragment x 1." The live broadcast camera pointed at his face, and the barrage frantically flooded the screen: "The liar is here again!" Lu Li smiled at the copper plate - because the next second, the empire's most authoritative treasure appraiser knelt down in front of everyone and called him "Master." The memory in that copper plate is the deed of betrayal signed by the treasure appraiser family a hundred years ago. Since then, Lu Li's live broadcast room has become the most terrifying place in the interstellar world: every piece of "trash" he identifies can reveal scandals about wealthy families, dirty materials about the empire, and even nuclear bomb codes before the civilizational rift. Some people offer exorbitant prices to silence, and some send fleets to silence them, but the sign-in wall behind him is refreshing new trump cards every day. Until he dug up the only evidence of the collapse of his hometown - and that evidence happened to be buried by his most trusted love.
