After the Villain Stops Causing Trouble, the Entire Court Eavesdrops on Gossip

After her quick transmigration missions ended, Pei Yanning was ready to go home and lie flat in comfort. But a System error sent her to an alternate world, where she became the real daughter reclaimed by the Prime Minister's household, a hopeless romantic. At first, she goes crazy and loses her mind over a scumbag, even slamming herself against a wall for him. Later, her love turns to hate, and she targets him at every turn, ultimately meeting a dreadful end. But what's romance compared to lying flat? The System even comes with a gossip service. She hasn't been enjoying her carefree days for long when Emperor Xuanwen suddenly goes off the rails, grants her an official post, and orders her to attend court with all the ministers. On her first day at court, the officials aren't exactly friendly toward her. [What? Someone wants to swap a civet cat for the crown prince and muddy the imperial bloodline? The old emperor has it rough.] That very night, the old emperor orders a cup of poison for the consort who tried to pass off another man's child as a member of the imperial family. [Major gossip: The Yongping Earl's household has been raising someone else's child all along, and they want to kill the earl's only biological daughter and take her place. Their real daughter has it so rough.] The Yongping Earl: ... [Oh my god, the Prince of Rui's heir not only mistook his savior for someone else, he also treated a man like a woman and tried to charm him. His brain doesn't work, and neither do his eyes.] The Prince of Rui's heir: ... Pei Yanning and the System are having a grand old time gossiping when they suddenly realize that nine out of ten things are terribly wrong. Not only has the old emperor gone on a killing spree, even the aloof crown prince has started looking at her differently.
