Gu Hang didn't say much, picked up a long steel reinforcement rod, its point sharpened to a fine tip, over two meters in length, and quickly climbed to the roof of the security room.
The zombie spotted Gu Hang and changed direction, standing beneath him with outstretched arms, reaching up as if to drag him down.
Gu Hang held the steel rod with both hands, aimed for the zombie's head, and with a piercing sound, stabbed directly through its brain.
With tools at hand.
He was able to deal with zombies as well.
"All set," Gu Hang said, placing the steel rod to one side and patting Wang Kai on the shoulder, "It'll be hard work, but we need to add some iron spikes to the surrounding walls."
"No problem."
Wang Kai was very interested in this kind of work.
He was exceptionally efficient at it.
Take the iron gate they had modified earlier, for example, its hinges, where it connected to the wall, had been reinforced by them, greatly improving its stability.
