About ten meters from the city wall, Lin Yue began construction again.
This time, however, he was building the initial type of wall, 35 centimeters thick and three meters high. This type of wall did not require any guard machine gun platforms for defense, only needed to be tall enough.
Surrounding the city wall, Lin Yue quickly established a new circle of walls, and within the area of these walls and the city wall, just like inside the city wall, he laid a layer of stones.
The main purpose of doing this is to prevent Lizardmen and beggars from digging tunnels within to attack from the inside.
Having done all this, Lin Yue brought out 20 remaining machine dogs from before.
Moreover, Lin Yue individually upgraded each of these machine dogs with a sniper rifle, with a bullet count of 30 rounds.
The role of sniper-type machine dogs is significant, and Lin Yue also believed they could easily pull off a headshot on the enemy from a great distance!
