My Supermarket Connects Past and Present. I Hand It Over to the State and Come Out on Top

Fresh out of a job, Su Xiaotang went home to inherit her family's supermarket. Faced with the sluggish economy, she planned to try livestreaming, but unexpectedly became bound to the Myriad Worlds Supermarket System. She transmigrated to a famine-stricken era to complete a mission, where she encountered a gang of looters smashing up the supermarket. She decisively turned herself and the System over to the state.

With the country backing her, Su Xiaotang thrived in other worlds.

During a famine, she collected gold, silver, and jewels, and brought back lost legacies.

In a post-apocalyptic wasteland, she brought back biological research materials.

In an interstellar world, she brought back advanced technology, giving science and technology a giant leap forward.

In the cultivation world, she brought back pills that strengthened the body.

Huaguo's economy, technology, and combat capabilities underwent a qualitative transformation. Its development took off like a rocket.

The countries eyeing Huaguo with hostile intent: "Wait, when did a mere Huaguo get so strong? Impossible. Absolutely impossible."

[PS: The worlds she travels between include famine-stricken eras, the apocalypse, the Journey to the West world... All kinds of worlds are being unlocked.]
