Led by several commanders, Su Xinghe entered Qingzhou Prefecture's inner city for the first time.
Unlike the bustle and prosperity of the four outer districts, the inner city felt more modern, tranquil, and peaceful.
There was just one tower, called Qingzhou Academy, that Su Xinghe found rather displeasing to the eye.
But other things soon caught his attention.
Exquisitely designed mechanical clocks occasionally appeared in the shops along the street. In the private dining rooms of restaurants, pendant lamps with a distinctly technological feel hung overhead.

Their Zhou Martial Sage Dynasty could obtain only a few relatively simple products. Things like guardian barriers and guardian divine weapons were restricted goods and could not be made widely available.
Su Xinghe asked why they did not use electricity, only to discover that Wu Cangqing did not even know what electricity was.

Even their Zhou Martial Sage Dynasty lay within a ruin.
Su Xinghe found this difficult to imagine. Even the three commanders had no idea
