A week has already passed since Leo had discovered the location of that evolved intelligent zombie called Dark Seeker.
During those days, the Dark Seeker had also realized that he had been discovered for a long time now through the eyes and ears of the zombies under his command and in panic, it immediately retreated back to London City but instead of holing up itself over there.
It instead brought with it a horde of zombies, numbering up to over half a million and with the additional fifty thousand of zombies that survived the clean up from Leo's men.
Which boosted their numbers, a little over six hundred thousand, a little over five thousand of those are mutated zombies from varying kinds while the rest are all just ordinary zombies.
And this horde of over half a million of zombies, started marching towards Cambridge City and they would soon arrive at the city in one day or two days tops.
