The city where the cyborg headquarters was located had been carefully designed and planned at the beginning of its construction. Not only were the buildings on the ground orderly, but even the underground was the same.
In order to prevent rainwater from accumulating in the city, the underground drainage system was built like an underground tunnel. From time to time, special sludge cleaning robots would enter it to maintain the smooth flow.
It would not be an exaggeration to call this place an underground city.
However, the sewer was still a sewer, and the rancid smell and darkness would never be less, no matter how clean it was.
A group of rats was startled and squeaked, scurrying around in the sewer.
Tang Zhen and the others covered their noses. They quickly passed through a section where sewage flowed and headed toward the region ahead.
