What?! I Actually Bound the Plane-Surfing Supermarket System

[Interdimensional Supermarket + Time Travel + System + Strong Female Lead + Rebuilding Her Hometown + Contributing to Her Country]

Song Li suffered a sudden heart attack while livestreaming and unexpectedly obtained a System that let her transmigrate between different planes, including alternate histories. After bonding with the System and regaining her life, she returned to her parents and opened an “Interdimensional Supermarket.” Thus began her journey across worlds: she saved the people of an entire city during a famine, gained special abilities in a world with both a surface and an underside, acquired advanced technology in a futuristic world, and found... something in prehistoric times.
