A day later, Great Xia began another massive wave of construction.
With reassurance and explanations from the government, the public did not panic too much.
With so many people taken into Great Xia's Underground Cities, many could only live in tents or bunk beds, so Great Xia decided to provide relief through work.
First, construction continued on the unfinished, essential sections of the Underground Cities. Materials for these projects had all been prepared in advance.
Projects that lacked building materials and were not important were abandoned entirely.
At the same time, Great Xia made using tunnel-boring machines to link the major Underground Cities into a network and connect them with high-speed rail its top priority.
The Underground Cities were not far apart, especially the 34 in the Arctic, which were only about ten kilometers from one another.
As for the two Underground Cities in Antarctica, they were too far from the Arctic, so connecting those two to each other would suffice.
Meanwhile, the New Hope Plan produced a wealth of new technology.
For instance, the rare earth metals refined by the Demon Clan could meet the needs of science and production.
The refined Energy Blocks opened up even greater possibilities for spacecraft and a wide range of weapons and equipment.
Gauss Weapons, for example.
The reason they had not become widespread before was batteries.
Having to carry a battery weighing dozens of kilograms on one's back, along with ammunition, just to use them was impractical in terms of both cost and manpower.
Now that was no longer a problem. Putting an Energy Block inside a firearm was enough to sustain high-intensity combat.
Spacecraft needed to be built, weapons needed to be upgraded, and robots and all kinds of electronic equipment needed a new generation. In fact, every technology could undergo
