There were also many cities with air quality index of this level. For example, some cities in Dongguang, Dongshan, and Nanhe were often in this level.
Every breath of air in these cities contained a trace of exhaust from cars and factories.
Of course, this was already very bad, but there was something even worse. A typical example was that danger warnings would be issued in Beijing many times, the air quality index would break through 150, and there would even be foggy weather.
As for those who were curious about the impact of this air quality, they could go out and take a deep breath of the fog when the weather in Beijing was foggy. They would know then.
Li Kai quickly arrived at the manor with the AQI detector.

He wasn't a slow-witted person, so he could instantly feel the fresh air in the manor.
As soon as they entered the manor, they were greeted by the refreshing air.
