The defense line of safety Sector No. 5 was connected to the other safety sectors, forming a sealed cliff that looked like it had been cut by an axe.
The rock was slippery and as hard as diamond. It was impossible to climb over it easily.
Not to mention that there were fully armed soldiers, cultivators who were good at killing, and all kinds of terrible war weapons on the defense line.
No matter if it was in the sky, on the ground, or through the ground, they could not easily cross the defense line.
The other safety zones were envious of such a defensive barrier, but none of them had the ability to imitate it.
Until now, only two sections of safety Sector No. 5 were facing the desert while the other sections were connected to other safety sectors.
However, on the long line of defense, there were heavy troops stationed in every direction, and there would definitely be no perfunctory measures.
