Five days has already passed since Leo took over Manchester City.
A lot has happened within those three days.
Upon returning and finding out that the city adjacent to them is already cleaned of "pest", the people within the Stronghold threw a huge celebration because of it.
After all, what Leo did was a huge step for mankind towards hope, hoping that humans would once again become the "masters" of Earth but what they didn't know is that Leo had other plans already.
So after taking over the city, Leo had immediately sent more men to rescue the still living survivors stuck around the city.
Every house and building were searched, with no stone unturned.
In the end, they only managed to rescue exactly one thousand and one hundred thirty seven survivors, which is really pitiful compared to the original population of almost a million before the apocalypse.
