While others are struggling to survive and slaying zombies in the apocalypse, I'm hoarding supp

There is a romantic pairing, but the female lead is always stronger than the male lead.
No entering the base, no forming a team
Two people, a cat, a dog, and a system travel to the apocalypse.
In her previous life, Luo Ning was the strongest female warrior in the Red Maple Base, but she was betrayed by her most trusted teammate.
After being reborn, she returned to her dream retirement home and settled down there to live out her days.
I built a small 200-square-meter farm on the roof of my house.
But she unexpectedly obtained a strategy system, leaving her speechless. This is the apocalypse; you've wandered into the wrong world.
The direct strategy system has been drastically modified to become the strongest auxiliary system, turning a retirement hut into a mobile castle and allowing you to open a family supermarket in the apocalypse.
The system is pressuring me to seduce the male lead, but he's acting like a vicious wolf.
Excuse me, but are you really that mean to me?
With his foot planted on the wolf's head, he said, "Tell me, who will be the master from now on?"
Unable to break free, the wolf could only say in frustration, "You are..."
After that, Luo Ning, along with the "Group Pet Conquest System 123," and the wolf-like male protagonist, colluded together in the apocalypse.
No, it's running a supermarket.
"Breaking news! Breaking news! The post-apocalyptic family supermarket is now open!"
"Vegetables, fruits, chicken, duck, fish, meat, clothes, medicine, and beverages are available for a limited time, first come, first served."
"Weapons, information, resources, connections, all at rock-bottom prices, great value for money."
"You might lose out if you buy it, or you might get ripped off."
"If you can afford the price, the customer is God; if you can't afford the price, the customer is a zombie."
"If you want it, I have it."
Don't miss it if you're passing by.
