This is also a reluctant gamble, for them, being able to do so is already the best outcome.
With so many zombies, if they had directly driven away just now, perhaps one or two vehicles might have escaped, but most of them would have died on the way.
It's more likely that they would have been completely wiped out in this horde of a hundred thousand zombies.
Li Tie and the others took turns to kill zombies for half an hour before switching with other people, the zombie bodies below had piled up to more than two hundred dead, averaging only a few seconds to kill one zombie.
Now, the pile of zombie corpses had become a small hill, but compared to the water tower over thirty meters tall, it was incomparable.
To make the zombies form a cone and stack up, it would take millions of zombies to reach such a height.
Because these zombies are not very agile, the slope of their pile is too shallow.
Therefore, they were temporarily safe.
