One day Lạc Long Quân told Âu Cơ: "I am descended from dragons, you from fairies. We are as incompatible as water is with fire. So we cannot continue in harmony." This said, the husband and wife parted. The man went to the seawards with 50 of their children, while his wife went to the mountainous region with the other half of the clan.

Genealogy
Lạc Long Quân's father was Kinh Dương Vương and Lạc Long Quân's mother is Long Mẫu Thần Long (Divine Mother Goddess of Dragons).
In Vietnamese literature
The books (from the 15th century) and ("Wonders plucked from the dust of Linh-nam", from the 14th century) mention the legend with Âu Cơ. Ngô Sĩ Liên commented on the somewhat primitive nature of the relationship between the two progenitors, given that Lạc's father Kinh Dương Vương and Âu's grandfather Đế Nghi were brothers.
Mythology
Slaying of the Monster Fish
During Lạc Long Quân's time, the people of Van Lang was still undeveloped and isolated. In the Eastern sea, there appears a giant Fish called Ngư Tinh (, Vietnamese for "fish monster" or "fish spirit"). This fish has lived for many centuries and had a mouth so big it could swallow an entire ship containing 10 fisherman in a single gulp. Whenever the fish swim, waves would reach for the sky, drowning many ships unfortunate enough to be caught in its path, and all the people passing through the area would become the fish's next meal. Ngư Tinh lives in a big cave under the sea, above the cave is a huge mountain which divides the sea into two areas.
Lạc Long Quân decided to offer his help to the people by slaying the fish. He built a huge ship, made a burning human-shaped piece of metal, then sailed straight towards Ngư Tinh's nest. There he held the human-shaped piece of metal up to trick Ngư Tinh. Ngư Tinh thought it was a human, so it opened its mouth and tried to swallow to burning metal. Quân then threw the burning metal into Ngư Tinh's mouth. Ngư Tinh 's throat was burning, it struggled and tried to sink Quân's ship. Quân then took his sword out and slew the beast, slicing it into three pieces.
Slaying of the nine-tailed fox
After slaying Ngư Tinh, Quân went down to Long Biên. There lived a one thousand-year old nine-tailed fox called Hồ Tinh (, Vietnamese for "fox monster" or "fox spirit"). The fox lived in a deep cave, beneath Rock Mountain in the west of Long Biên. This fox often disguised itself as a human in order to lure the village men and women, then bring them to the cave and devour them. This fox has been harassing people from Long Biên to Tản Viên mountain for centuries and the villagers were so afraid of the fox that they have to leave their homes and farms to other places in order to live peacefully. Quân brought his sword to the beast's nest and set out to slay the beast, just as he had with Ngư Tinh before. When Quân reached the cave, the fox smelt the scent of human flesh and emerged her lair to confront whoever it was who dared trespass into her domain. Upon seeing the beast, Quân then used magic to call the elements of wind and thunder to trap Hồ Tinh and after 3 days, the beast was weakened and attempted to flee from her attacker, but Quân caught the demon fox and decapitated her. Quân descended into the cave and rescued everybody that was still alive and returned them back to Long Biên.

Vietnamese creation myth
Descendant of Dragon and Fairy
Based on the 16th century mythical genealogy , Lạc Long Quân is the son of Kinh Dương Vương and Long Mẫu Thần Long, the dragon goddess that rules the sky and the ocean. He was married to Âu Cơ, the daughter of the sixth Flame Emperor Đế Lai. Âu Cơ gave birth to a sac of a hundred eggs, which were hatched into a hundred boys. One day, Quân confessed to her: "I am a descendant of the Dragon, you are descendant of the Fairy, fire and water cannot live together in harmony." The two of them then divided their children. Fifty sons followed their mother to the mountainous north, the other fifty followed their father to live in the south; these children are ancestor of Vietnamese and Khmer. The oldest brother followed Âu Cơ to Phong Châu (Phú Thọ), became Quân's successor and ruled as Hung King. It's the story of the earliest divorce in Vietnamese history.
