Zhongjing was far larger than Qing Province. Its city walls weren't simple physical barriers, but a complex array of extensive infrared surveillance and all sorts of high-tech devices.
Wu Liangchen drove along a small road outside the city, observing the surrounding scenery.

The defenses of Zhongjing were truly strict to an absurd degree.
"This place is as secure as a fortress!" Song Ling'Er, who had also been observing closely, couldn't help but murmur.
