Dongyi were the barbarians since the ancient times and they were not viewed as ordinary human. The people of this tribe had unique blood vessels and were born with supernatural powers while the Kings of the tribe had the ability to fire a bow with a force of millions of pounds.
A warrior from the Dongyi tribe who was based on a deserted island on the Eastern Sea once fired nine arrows consecutively and killed the shapeshifted Nine-headed Demon King. But surprisingly, the warrior only lived for a couple of hundred years.
The incident was recorded in the 'Strange Tales of Divines and Demons' and Shen Lian felt unbelievable when he read the story.
