Producing artificial blood serum with the demonic blood of a monarch level above the fourth realm? Wasn't that something only those super-scale alien corporations, or the top-tier alien families of the Federation, could manage?
The 'artificial blood serum' for the enhanced Martial Cultivators was made from extracting the marrow and refined blood of the demonic creatures from Celestial Star.
In short, human bodies cannot produce blood refined with a large amount of Ether elements, so biologists extract the marrow and refined blood from the demonic creatures of Celestial Star to create 'artificial blood serum' as a substitute, allowing the enhanced Martial Cultivators to complete the third realm of blood cultivation.
The East Asia Republic is a bit more particular, allowing only the extraction of marrow from demonic creatures.
