Apart from extraterrestrial mining, many other crucial industries could also benefit from such large-scale construction.
For example, heavy industry.
Building cities of this scale naturally involved various large-scale machinery. Human civilization was digesting the Desert Tower civilization's technology and industry while continually learning the advanced technology from the Chosen One Mall for city construction. Growing continuously in this manner was essentially killing two birds with one stone.
Moreover, unlike the Trial Period, the construction did not need to be completed within a short time; in fact, taking it slower could even be better.
A slower pace allowed for more perfected technology, resulting in better-constructed cities without affecting people's cultivation.
After all, it only needed to be completed within five and a half years.
In the following two months, several other key projects gradually began to take shape.
For example, the spirit field.
