Chapter 145: Fighting Alone at Black Hole Level

There are no iron rules on the border battlefield; the cosmic nations face life and death, wielding powerful technology weapons, terrifying biochemical radiation, and frenzied body bombs... every means can be utilized, as long as it can win the war.

Yet, among the many cosmic nations, there exist certain "implicit rules." Although not explicitly stated, every cosmic nation abides by them.

And among these implicit rules is one: do not cross the battlefield.

At first glance, this appears to be merely a tacit verbal agreement, without any coercive force of sanction, yet not a single cosmic nation dares to break this implicit rule!

Sha Na was precisely in violation of this implicit rule, which is why he was so cautious, unable to let anyone who saw him stay alive.

He deeply understood that once his crossing of the battlefield was discovered, the consequence would be the erasure of his life!
