After Traveling Through Time, I Opened a Canteen in the Apocalypse

[Apocalypse + time travel + system + free travel in the real apocalypse + growth-oriented heroine + not the Virgin + decisive killing] Lin Wan, a fresh graduate, failed both the postgraduate and public examinations. When he returned home and was about to lie down, he found that his parents' supermarket had already closed down. Not long after taking over the canteen at the entrance of the village, she accidentally traveled through the apocalypse, bound to the apocalyptic canteen system, and freely traveled between reality and the apocalypse. The materials she bought in reality were sold in the apocalypse, and she happily made a fortune. The inside and outside of the store are separated from life and death, providing safe shelter, selling materials, and trading crystal cores to survive. In the post-apocalyptic world of 2080, when zombies are everywhere and order has collapsed, a canteen with rotten salted fish has gradually become the safe haven that everyone dreams of in the apocalypse.
