In the Tongcheng of the Great Tang Empire, countless factories are operating busily, presenting a scene of industrial prosperity. The factories here are like steel behemoths, devouring raw materials day and night, and producing various industrial products.
Inside the factories, machines roar, and the workers on the production lines skillfully operate the equipment. Each product undergoes meticulous processing and inspection to ensure outstanding quality. The black smoke billowing from the chimneys is an inevitable byproduct of industrial production, weaving into a dense smog in the sky and adding a unique color to Tongcheng's skyline.
Although it has passed environmental audits, this is still the most polluted place in the world. As long as you see those sky-obscuring chimneys, you know the air here is certainly not fresh.
