Although the Flaming Red Kingdom has several thousand provinces and enclaves, its total population is less than ten billion. Despite the size of its territory being dozens of times larger than that of Blue Star, its population is comparable to Blue Star's.
The most populous enclave within the Flaming Red Kingdom is Gemstone Country, with a population of five hundred million, covering an area three to four times that of Hua Xia Country. In the vicinity, it is considered a densely populated enclave.
To quickly increase the population, Radical Speed Country had a method: introduce Crawling Demons and let them breed rapidly.
Crawling Demons have short lives and problematic intelligence, at most reaching the level of human children, but their physical constitution and structure are suited for hard labor.
Such as farming, mining, transportation, and sanitation.
This was already quite remarkable.
