Oath of Allegiance

As the country with the strongest army in the mainland, the Haiyin Empire's specialty is the mixed blood of the goddess born after a long bloodline selection. When they become adults, they will be incorporated into the imperial guards as direct aides who are only loyal to the emperor himself. Those who can cast teleportation magic and city-destroying curses at will are undoubtedly the most terrifying war machines on this land. However, in fact, these demigod forbidden troops are far from being as good as the legends say. "They don't have the moral concept of human beings, they are simply a group of scumbags who play games in the world and are only interested in profit!!" (Not edited synopsis)
