Actually, as this group of people stood outside the city gate pointing and discussing, the elders on the city walls had already noticed them.
They didn't rush to react, instead, they wanted to see exactly what these people were planning to do.
Of course, they weren't just watching; they used radios to pass information to the guards inside the base, even the Heavenly King Guard heightened their alertness.
If this group harbored ill intentions and tried to attack the city, then the Northern City Base's defensive forces would rapidly assemble to confront the enemy together.
They had experienced such situations several times in the past few months.
There were zombie sieges, other bases attempting to rob them, and mutant animals launching sneak attacks... Under Heavenly King He's wise leadership, they had defeated the enemy time and again.
Moreover, through these real battles, all the survivors of the base learned and honed their Martial Arts.
