I Won the Favor of the Six Palaces by Guessing Blindly

Shen Tangtang transmigrates into the body of a disgraced consort confined to the Cold Palace, and discovers she can "hear" the one secret people most want to keep hidden.

She doesn't rely on cleverness. Instead, she rambles and blunders into the truth, accidentally hitting the mark every time.

She thinks she's making things up to amuse the emperor, but everything she says is the absolute truth. The emperor, meanwhile, believes she's a master with unfathomable depths.
