After everyone boarded, the Surface Commuter Vehicle slowly started moving.
The vehicle first entered a broad ramp leading upward, with silvery-white alloy plates lining both sides and rows of steady lights overhead.
As they climbed higher, even the air around them seemed to change.
Soon, the view ahead opened up.
A sixteen-lane Underground Industrial Main Arterial Road appeared before them.
Eight lanes extended outward, while eight led into the city, separated in the middle by a thick barrier strip.
Traffic streamed endlessly along the road. Heavy transport trucks, Engineering Robot carriers, material haulers, personnel commuter vehicles, and unmanned transport platforms moved among one another, orderly and without the slightest confusion.
A convoy was passing beside them.
Each transport truck carried enormous silver-gray alloy components secured in place. Some were ring-shaped frames, while others were thick load-bearing plates.
Others were completely concealed beneath protective covers, making it impossible to see what they carried.
"Are all these being sent to the planetary engine construction sites?" Lin Mo asked.
Chen Jianguo nodded.
"Some of the parts are produced by Tianyong City's Small Universal Factory."
"The Small Universal Factory mainly handles high-frequency supply parts, standard connectors, repair components, and some special-purpose cables. It manufactures them quickly and can adjust production at any time to meet construction needs."
"The truly large load-bearing structures, giant energy pipelines, and engine main-body modules are produced by the hundred-kilometer-scale Universal Factory on the surface."
"Once they're finished, they're delivered directly to the various construction sites through the Surface Logistics Network, and Engineering Robots handle the lifting and assembly."
Zhao Gang watched the endless traffic outside the window and spoke with feeling.
"In the past, just coordinating materials for one large power station was enough to give you a headache."
"Now ten thousand planetary engines are being built at once,
