In her previous life, the female protagonist was sent to a eunuch. After she was reborn, she found that there was a treasure in the secret passage of her house. Was this the reason why her family was destroyed in her previous life? This was a very interesting plot. According to my knowledge of web novels, this plot might have a different development. Here are some possible scenarios: - In her previous life, the female protagonist was sent to the eunuch because she had some kind of defect or crime that was hated by the emperor or others. In this world, they might be sent to a eunuch's family to be isolated and abused. - After rebirth, the female protagonist might feel guilty and confused because she didn't know her past. She might start looking for clues to discover the reason why her family was exterminated in her previous life and try to avenge herself and her family in her previous life. - The female protagonist might discover that the treasure in the secret passage of the house would become an important discovery, triggering a series of adventures and stories. She might be able to connect with her family in her previous life to explore this secret and unravel the truth of her extermination in her previous life. - The rebirth of the female lead could be a turning point that would change her fate and the direction of the story. She might become a hero or heroine, bringing a twist and climax to the story. These are just some possible plots, depending on the author's imagination and creativity.
