For a final boss this whore (literally as it seems) is quite a let-down. It looks like all she has is that weird talisman, however JP already *****slapped one system. I really doubt that talisman really has a 80% chance to work.
You call her whore but ... other that that, you do know she is the classical common protag from almost all this kind of story, right ? Beside ... "whore" ? She don't f*ck with other man, she only send her "maidservant bodydouble" do it. Well, she as a illegitimate daughter, so she as do it with other mans, but so what ? how many protag male have big harem and go f*ck there and here all the time ? What the difference betwen them ? As for the system ... yes, clearly is goal is to break "our protag" macking more drama, and protecting "the whore" (like you said) to become the most powerfull of all ... like almost all system in so many story. Macking the underdog who "as be sliged" and "live a poor live" and other cliche-plot to become the king and live well. Have you never ask yourself why system do that ? Maybe i'm to paranoiac, but this as alway be strange for me. Beside, do you have never cringe before, when author make protag kill so many people, including maidservant, servant, poor soldiers and many more and forcefully make this be "right" ?
Did she realy think of all this bulsh1t the System as said to her ? I have alway thinking it was strange "system" in story don't abuse and use their "linked-protag" for themself, and find strange the protag never doubt or ask about the truth of what is said. And the real goal of the system. Now i know why ... Greed and lust make people blind, and self-estime make them forgot all their own wrong and misdeeds. Venting and targeting all the bad on the shoulder of other. That, and the fact protag are f*cking idiot or big trash in 80% of this kind of story. And finaly ... you know what's is realy funny, but in the same time disgusting ? This crazy girl full of herself, blinded by greed and thinking everything can only go good for her, and think all little thing who don't come from despicable sheme who "wrong her" ? Well ... she is exactly the copi-paste protagoniste character from almost all Isekei/cultivation story type like "the black-belllied miss smuck", "the unparallele miss bibule", "the master pharmaciste/doctor young miss blabla" and other "vicious unparallele (but of course pure and great) medical/assassin" who take almost 80% of "story for female teenager". The only part is, she is show there like a antagonist, the foe, the bad one. But when you take just a little time to read betwen the line, she is exactly that. A typical female MC in Cultivation/Isekai Chinese story. The only change is the author not forcefully making her the good one, and the center of the story. And of course, letting go wild and break thing, when in other story the "unparallele MC" remaind cold and aloof. But in fact, this change nothing : the way of thinking, the way hey do thing are exactly the same. One is "protected by the plot-armor" and the other not.
