Quick Transmigration: After Binding the System for a House Full of Children and Grandchildren

Zhu Yingying had always thought of herself as utterly ordinary. If life were a novel or a TV drama, she'd be no more than a background character, with no potential to become the protagonist. Yet through a twist of fate, she ended up bound to a [Full House of Children and Grandchildren] System. Her little head filled with big questions, she couldn't help calling out to it: System, you there? You know my motto, right? System: Of course. That's why I chose you. Only later did Zhu Yingying understand what the System meant. This System, which was slapdash about its work, really was a perfect match for her, since she was just as halfhearted about her own job. They were made for each other. World One: The original host had a big family. Now I have to work hard raising the kids (Ancient Era) World Two: It's the space age, and people are still pressuring me to have children (Interstellar) World Three: I'm about to ascend, and I'm still expected to deal with my descendants' problems (Cultivation) I'm terrible at writing blurbs, so just give this a try for now. If it doesn't work, I'll revise it!
