The rumbling was drowned out by the continuous peals of thunder erupting across the sky.
Occasionally, a streak of lightning flashed.
The entire Qinggang City seemed to resonate, while the buildings on the ground emitted creaking sounds as if they could no longer bear their own weight.
Several plumes of thick smoke rose in the distance against the downpour, while boiling flames seemed to burn fiercely in the sky.
For a city that had long since fallen after the war, such commotion seemed rather strange.
But by then, few people cared anymore.
Because deep within the seemingly unreachable fog, black lines were rapidly converging and growing larger until—
"What's that!?"
Several Qinggang Soldiers resting on the watchtower ahead stood up curiously. They picked up the Biological Scanning Detection Monoculars hanging around their necks and observed the black lines.
Hmm.
Although there was a trace of heat detected, it was not particularly strong, and the readings had not reached the level of living creatures.
After taking a look, they could basically confirm that these were mutated insects that had crawled out of cracks because of the rain, rapidly marching through the gaps in the city.
Over the past several decades, this had happened more than once or twice.
Almost every time a Mutated Beast Tide broke out, these pitiful little creatures would leave their homes and head for safer places to survive. Only after the beast tide ended would they quietly return, bringing the people of this city an early warning and alert—
An alert?
Several guards lowered their monoculars, their expressions suddenly turning solemn.
The last Mutated Beast Tide had broken out four years ago, and its scale had been: Level Three.
According to the New Alliance's classification system for this thing, there were five levels in total.
Level Five
