Weapons of Mass Destruction - Chapter 357: Pump these numbers up

Mu Jingzhe transmigrates into a book filled with sweet, doting love to become the useless supporting character who serves as a foil to the female lead. She also becomes the stepmom of five kids to her recently deceased husband.

What’s not to love about my new life after transmigrating into a Pet-centered world?
There are mighty creatures that come in all shapes and sizes. They can either be cuddly companions, helpers in your daily life, daring scouts or strong fighters. Or all of the above. Not bad, huh?

I have a family, but the fact is completely overshadowed by my younger sister. She thoroughly hates my guts, and she makes sure that I know this. Every. Single. Day.
Did I mention that she’s disgustingly talented while I am a bottom feeder? A terribly handsome one at that.

I have free rein to run the family business on my own. A small and quaint Pet Store. It should have been great if not for the fact that the previous owner of this body was born with ZERO affinity to handle Astral Pets…

It wouldn’t be a proper transmigration without a gimmick or a system to pave my road to greatness, don’t you think? I have one, but I don’t know if I would be better off without it…

TL Description: Eat The World Tree is about a strange guy, who happens to be extremely curious and unable to stop himself from acting on his curiosity. The MC makes a slight mistake and travels to another world, and must fulfill specific quest or face varying levels of consequences (normally death).

After switching bodies, Jiang Nan Shu becomes the villainous true daughter in a melodramatic tale and is bound to an all-encompassing revulsion system. If everyone's level of disgust for her reaches 100, she can return to her original world with a prize of ten billion. Being reckless is just one of her many skills. Starting with a disgust level of 89, Jiang Nan Shu sets a modest goal for herself: to live a life collecting easy money within six months. Unbeknownst to her, everyone can hear her inner thoughts!When facing the domineering CEO eldest brother, she says outwardly, “I think this project is excellent and will make a fortune.” Inwardly she thinks, “I hope you don’t go bankrupt! Once you're out, I'll steal your company's secrets.”When dealing with the indifferent medical second brother: outwardly, “The food at your colleagues' gathering looks so appetizing.” Inwardly she thinks, “I'll switch tables when the second brother picks food, to avoid catching any diseases from him.”When facing the sickly research third brother, she says outwardly, “Third brother, you're amazing to conduct such tough experiments, keep going.” Inwardly she thinks, “I’ll gracefully exit before your experiment explodes.”When interacting with the pop star fourth brother: outwardly,“These songs suit you so well, sing them all, and fame is just around the corner.” Inwardly, “Just wait for the news to break about your tax evasion.”When advising the love-struck fifth brother: outwardly, ”She's taking an hour out of her busy schedule to be with you because she loves you.“ Inwardly, ”You’ve been turned into a grassland of green; your goddess has a different companion morning, noon, and night. Bet you didn't see that coming!“As the male protagonist looks at her with increasingly deep eyes, saying, “Let's be together,” Jiang Nan Shu weeps, saying, “Don't let your sister misunderstand, I'm not worthy!” Internally, “Money's hard to earn, crap's hard to swallow, the life of a supporting character matters too!”However... why does she end up as the darling of the whole group in the end?
