Although Li Yao did not know much about the demon race, he had some basic common knowledge.
Hierarchically speaking, the demons could be classified into four levels, namely saint-blood, silver-blood, bronze-blood, and black-blood.
The saint-blood demons were the royal families in the dynasty of demon beasts that had lasted thirty thousand years. They boasted mysterious and unpredictable strength. It was said that they could even communicate with the gods and trigger the powerful techniques of the ancient demon clan temporarily.
However, in the era of the Star Ocean Imperium, the saint-blood demons had all been slaughtered, if not exterminated, by the Supreme Emperor.
After ten thousand years, the saint-blood demons were rarely seen, if they still existed at all.
The silver-blood demons were the ruling class. Most of the demon kingdoms and demon cities in the Blood Demon Sector were mastered by the silver-blood demons.
