On the seventh day of the city's food shortage, supermarket operations manager Zhou Ye awakened his shelf storage capacity and moved the entire supermarket into an underground shelter bit by bit. Former fire captain Tang Yan guarded the entrance for him, doctor Su Tang maintained infection isolation, and He Zheng discovered that the underground passage led directly to the disaster experiment area. Food can save people and create domination: when Luo Qiming instigates survivors to seize power and Wei Mingchuan brings deals for convoys outside the city, Zhou Ye must use a mobile supermarket to maintain the final order in the city.
