Chapter 500: Return to Base

Whoooo—

The shrill and loud air-raid siren suddenly erupted within Changhe Base.

The civilians were startled, thinking the zombies had breached the base. Already reluctant to venture out due to a heavy snowfall, they were now even more afraid to leave, frantically locking their doors and windows.

However, the alarm had started abruptly and ceased just as unexpectedly.

It lasted for perhaps twenty or thirty seconds before the siren noise abruptly disappeared.

At the same time, Gu Yun's voice came through various loudspeakers, explaining that the siren had been just a test and instructing everyone not to panic, as the base had not been invaded.

"It was just a test? You scared me to death!"

"Could you notify us before the next test? I didn't even have time to pull up my pants..."

The credibility of City Hall was still very high, and the civilians breathed a sigh of relief after hearing their explanation.

But on the other side, the City Defense Army was on high alert.
