Ever since Tang Zhen had returned, Holy Dragon City had started to become lively again.
The weapons and equipment exchanged from the Asian and American alliances were quickly arranged by Tang Zhen to ensure that there were no blind spots during the defense.
As the Holy Dragon city's area continued to expand, the difficulty of defending the city also gradually increased.
Fortunately, when Tang Zhen was transforming the terrain, the erected defensive mountain peaks were all tall, steep, and smooth. Unless one used special tools, it was impossible to climb up!
Tang Zhen was busy but the others weren't idle.
The Holy Dragon city's soldiers were also extremely busy. They familiarized themselves with the new weapons every day. From time to time, the sound of concentrated gunfire would ring out from the valley behind the Holy Dragon City.
