The celebration lasted three days and three nights.
Not only around Eternal Spring, but every rebuilt city on Blue Star celebrated extravagantly.
Over the past two years, a total of thirty-two major cities had been successfully rebuilt on Blue Star.
These major cities were mainly concentrated within Huaxia Country, while only a few capitals in other countries had been rebuilt.
However, all these cities were reconstructed according to Feige Hub's urban standards, with Holy Song Towers built at their centers, clusters of buildings thousands of meters high around them, and large numbers of machines and intelligent mechanical lifeforms manufactured to assist with urban construction.
AI Blue Whale possessed the galaxy's most advanced technology, so Blue Star had no technical difficulty building cities comparable to those on Hub Planets. In some respects, they were even better.
However, constructing cities like these consumed enormous amounts of resources.
The resources needed to build a single city now exceeded the total resources Blue Star had once needed to build all its cities!
And resources were not the only issue; energy was also a massive problem.
Fortunately, all these problems could be solved somehow.
Su Yu had been busy over the past two years, spending all his time on Civilization Binding. But that was fine. In the near future, he would personally head to the Sun to construct a Dyson Sphere, covering it with solar panels and collecting all its light and heat energy to send back to Blue Star.
As for resources, Blue Star Humans would build a large number of space mining stations to extract mineral resources from the Moon, Mars, Venus, and even Saturn, then bring them back to Blue Star for urban construction.
In short, Blue Star Humanity would rebuild its old cities into major cities ranked among the most technologically
