My Days of Opening a Supermarket in the Apocalypse

After the cat Shan Nai was struck by lightning and died, she was bound to an apocalypse supermarket management system.

When she opened her eyes again, outside were zombies and mutated beasts everywhere, with no water, no electricity, and no signal. But inside the supermarket, it was absolutely safe, and she had no worries about food or drink.

As long as she upgraded the supermarket to the highest level, she could also receive a dream gift package~

Shan Nai thought, "I've been a cat for so long, being a cat boss of a supermarket is also acceptable!"

*Trigger Warning: The female protagonist is absolutely not a 'white lotus'; evildoers will certainly be dealt with! However, she is not a cold-blooded killing machine; she won't kill someone just for merely having bad intentions. A gentleman judges by actions, not by thoughts.
