Reborn: Leading Goddesses Against the Apocalypse

Ethan Shaw wants to get through the T-virus outbreak in S City, which he has already lived through once. What he knows about it is worth less than it sounds, since the undead keep changing form and the methods that kept people alive last time stop working on them. Then a system wakes in him. Killing the infected earns him members for a team it calls the Professional Goddess Squad. He gets An Xiaoran clear of the infected and the team has its first member. The two of them find that the storage space the system gives each of them can be shared between them, and they go through the city stripping it of supplies, from the warehouses behind the malls to the slaughterhouses.
