With an Infinite Supermarket System, I Save the World and Strike It Rich

[System + multiple worlds connected + supermarket with unlimited goods + building wealth + love at first sight + one heroine and nine male leads + cozy daily life]

Song Chengnuan is a recently graduated college student who lives at home off her parents and is a total mama’s girl. One day, she wakes up to find a new door in her room. Just as she’s about to stick out a curious little foot and see where it leads, a System calling itself the Salvation Supermarket binds itself to her. “Host, let’s save the world together,” it says.

After confirming she can return at any time through the door, Song Chengnuan agrees.

She opens the door and steps into a new world where a zombie apocalypse has broken out. The System unlocks a supermarket for her, with an unlimited supply of free goods.

Song Chengnuan fools the naive little System, telling it that people can be cruel, and if everything is free, some people will come to think they’re entitled to it. They should set the prices a little lower instead. The little System thinks its Host makes a lot of sense and agrees, and Song Chengnuan begins her path to riches.

In the first world, a zombie apocalypse, people struggling to survive believe she’s come from a high-tech world to save them.

In the second, an ancient world stricken by famine, starving people believe a goddess has descended to save them from misery.

The third, the fourth, and so on…

Song Chengnuan and her little System both get what they want.

Song Chengnuan gains endless wealth and an immortal body.

[Content warning: Song Chengnuan isn’t forceful by nature. She feels for ordinary people struggling to survive, but she isn’t a selfless do-gooder.]

[Content warning: This story has nine male leads. The heroine always holds the dominant position, and all nine men are chaste in both body and heart.]
