The city wall, when first poured, looked just like a mountain of ice.
Engineers led a unit of engineers, along with a large number of survivors, to conduct quick repairs outside.
The ice piled at the base was cleared away, denying the zombies any steps to climb up.
The smooth wall surface, with an added layer of slick ice, had no place at all that could be climbed.
But inside the city, it was different; ice has a great malleability, and people directly carved out steps that led straight to the top of the wall.
Dust was sprinkled on the ice surface to prevent people from slipping while walking.
This ice wall is a feature of the north, as only such cold winters can allow it to form quickly.
Not only the outer wall, but the walls of the main city district and the core area were also heightened and thickened.
Those watchtowers hidden in the mist were directly sold by Ye Fan, then replaced with 11-meter-high watchtowers.
