Archaeological graduate student Lin Yuan was in danger when he went to the tomb, and when he was about to die, he activated the [Historical Echo System]. By touching cultural relics, he can see the obsession of the original owner; by identifying the authenticity, he can see through millennia of lies. A witch who was burned to death is hidden in a jade wall during the Warring States Period; forty years of waiting are sealed in a bronze mirror from the Tang Dynasty; an unwilling roar is engraved on a fire blunderbuss from the Ming Dynasty. When the entire Internet was questioning that he was a liar, Lin Yuan started the live broadcast - "Today, I will tell you a story from two thousand years ago." Gu Nian, a cultural relic restorer: "I didn't believe in ghosts and gods before, until I saw him crying against a stone." Lu Heng from the Ninth Department: "I don't care about the rest. If you can solve the case, you are a good comrade." This is a story about listening. Behind every cultural relic, there is a name worthy of being known to the world.
