Madman said, "According to the spies' reports, there are many, indeed a vast number, currently densely crossing the border. You all know that once the numbers reach a million, it becomes very difficult for the human eye to keep count."
Although the Southwest District is economically underdeveloped, it's vast and rich in resources, and with a high birth rate, their total population is about 1.3 billion;
The Western District has 740 million people;
Central Continent Zone has 100 million people;
The Southern Region has 1.9 billion;
The Yellow Sand District has 500 million;
The Southern Region is now gathering nearly 4.6 billion players, deducting the repeated portion, there are still a solid four billion left.
