Qian Fei would never have thought that the "Dream Supermarket" system would be the key to the end of the world.
Doomsday, zombies, mutant beasts.
Is this the beginning of mankind’s demise, or the beginning of new life?
Qian Fei knew nothing about this.
He only knows that by working hard to upgrade the supermarket, it is possible to find family members who are living outside.
But facing astronomical upgrade conditions, he is not the only one who can complete it!
"I want all the survivors to become my customers and let them help me upgrade the supermarket." This is Qian Fei's oath, and Qian Fei's only hope to find his relatives.
