The Lord of the Underworld, Shen Yuan, married Lin Shu, the human embroiderer, during his love tribulation. After returning to the throne, he found that Lin Shu missed him and burned huge amounts of paper money in his likeness, directly collapsing the underworld's currency system and triggering severe inflation. Shen Yuan learned that his wife had been bewitched by a liar, so in order to save her, he personally went down to earth to expose the scam, exposed the identity of the King of Hell and took her back to the underworld. Relying on his extraordinary wisdom, Lin Shu used merit as an anchor to launch new coins to save the underworld economy, and eventually became the Queen of the Underworld. He joined hands with Shen Yuan to govern the underworld and gave birth to an heir, creating a sweet story that spans Yin and Yang.
