The wind began to howl.
In less than five minutes, zombies had piled up to a height of eight or nine meters.
Li Yu ordered the mobile switch blade to be activated.
Ka-ka-ka—
The mobile switch blade sped up from slow to fast, and eventually, its speed kept increasing.
The merciless blade bisected zombies at the waist one after another.
The other zombies below, seeing the falling corpses, rushed up to snatch and devour them.
And the zombies behind them charged at the walls with even more frenzy.
Before, when there weren't as many zombies, simply turning on the mobile switch blade would result in some of the zombies being killed, and those below would naturally scramble for the remains, causing the height of the pile to decrease.
But now, with too many zombies, the fallen corpses weren't fully consumed before more zombies that missed out charged forward.
This led to the pile's height not decreasing.
