Over Tai Du City, it took the Thunder Dragon roughly two minutes to circle the city once.
By the time it returned to where it began, all the Mutated Beings attacking the city, whether Mutated Animals or Mutated Insects, regardless of their levels, had been turned to charred remains.
The Defense Forces atop the city walls felt a sense of having narrowly escaped a catastrophe.
But before they could take any further action, they saw the terrifying lightning dragon depart toward the distant horizon.
At the same time, they also noticed that the Thunder Dragon wasn't flying aimlessly; it followed the main roads.
And during this process, it continuously unleashed lightning, striking down any Mutated Beings that came within 1 kilometer of the highways.
This scene left many soldiers exchanging bewildered glances, somewhat unable to comprehend why the Dragon Lord was doing this.
