It All Began After the Black Fog Descended

Black fog descended upon the world. Everyone was left with nothing but themselves, as all other possessions were wiped away in an instant. Fortunately, everyone was issued their own little four-wheeled vehicle. In this perilous fog, it was the only thing they could rely on to survive. Just as Zhao Xiaoyi was preparing to drive recklessly through the black fog, he was astonished to discover that something seemed to be wrong with his vehicle's mind. How strange.
