From the name of Shelter Number 9, one can see.
With Number 9, there's Number 8, 7, and many more.
In fact, Lv Bai had learned about such information a long time ago.
The sequence of shelters is actually ranked by scale.
Of course, the size of Shelter Number 9 is already exaggerated enough; those shelters ranked ahead, even if larger, are still within the same magnitude.
The combined population of these top ten super-massive shelters can reach two billion.
These ten shelters are essentially the last foundation of human civilization.
Beyond that, shelters in the double digits, or even triple digits, are very small, not even worth calling a spark, and whether there are people alive inside is unknown.
So, although the City Council issued notices to all shelters, they only care about the responses from the top ten shelters.
The basic radio operation is very simple, no need for professionals; Xiao Zhengyan could use it himself.
