On the first day after she transmigrates, Lin Wanxing receives a big welcome package from the System:
[Beginner Mission: In the main hall of the marquis's estate, shout "I'm a pig" three times at a pillar, then imitate a pig's squeal.]
Lin Wanxing: "??? System, get out here! I promise I won't beat you to death!"
System: "Reward for completion: 'Beginner's Thick Skin.' Punishment for failure: 'Walk bowlegged for a whole day.'"
Lin Wanxing: "...Fine, you win!"
From then on, the Great Zhou Dynasty has a new "remarkable woman"...
Her legal mother makes things difficult for her? She puts on a show of "smashing a boulder on her chest" right there and then (it's actually a foam rock redeemed from the System), while calling out, "Everyone, type '666' in the chat!"
Her scumbag fiancé breaks off their engagement? She runs through the streets with a megaphone: "So-and-so is heartless, lives off women, and loves to fart!"
Even when she meets the emperor, he asks her how to govern the country, and she pulls out a "buzzer" redeemed from the System. "Your Majesty, I think we should set up an ancient version of a 114 public-service hotline!"
The assembled officials: "..."
The emperor: "...That's kind of interesting."
Meanwhile, Prince Xiao, whom she's flirted with using the corny line, "Honey, I went farming today. What did I grow? My unwavering devotion to you~", is now standing in front of her door, his gaze dark. "Lin Wanxing, don't you think it's a little unfair to flirt with me and then run away?"
System: "Ding! 'Ultimate Push and Pull' mission triggered: Host, tell the prince, 'Don't fall for me, it won't end well, unless you can take me out for hot pot!'"
Lin Wanxing: "...System, you really know how to ship a couple."
This is a remarkable novel where "everyone else transmigrates to build a career, but I transmigrate to mess with the System!"
