[Quick Transmigration] My Years as a Cousin

Li Shu was sure she had died. But now, somehow, she was alive again, with a System in her head that claimed to have saved her and had a mission to save the Creator God. Having received such a great favor, she felt she ought to repay it. Li Shu didn't mind following the System to save the world, but... Li Shu: I'm fine with transmigrating to different worlds and playing the younger cousin. But what exactly am I supposed to do? System: The rules say we can't tell you. You'll have to figure it out yourself. And so... Crash and burn x1 Crash and burn x2 Li Shu: So basically, I just have to win them over. I can do that! System: Exactly! You're so perceptive. I knew you could do it! And so... Crash and burn x1 Crash and burn x2 Crash and burn x3 Li Shu: Flips table! There is definitely something wrong with the scoring! Emmmmm... Wait, I think I've uncovered a secret? Survival Guide: Note: The first world has a rather unusual style because it sets up later events. If it's not to your taste, you can start with the second world instead~ 1. Although the tags say female supporting character, the protagonist usually counts as an extra in the source material. 2. This is quick transmigration. Winning people over isn't the main way to complete the mission, and most worlds aren't primarily about romance. 3. There is a romantic pairing. Worlds centered on romance will be marked in advance. 4. The System in the blurb is noisy, but the System in the story is mute. That's all for now. If you're okay with all that, hop aboard!
