While others were still carefully collecting supplies, Xu Tianji had already built a steel city wall tens of meters high, with various heavy artillery and high-tech city defense weapons lined up in a row. With the support of the system, Xu Tianji pulled up mechanical troops one after another. Powerful wild beasts, zombies dominated by numbers, and various scheming strangers all looked so ridiculous in front of Xu Tianji's mechanical corps...
