Who knows the story about the black dragon in Dragon?

Dragon nidhogg also hollowed out the deep roots of the tree of the world at this time, and the tree is going to die. At this time, the "atrium"-the serpent around Midgard-Jormungander also woke up from the mud bed at the bottom of the sea, churning his huge body, and his long tail set off huge waves, engulfing the mountains in the "atrium" and the seawater rushed into the sky of the "Kingdom of the Gods". From the mountain-like waves, the serpent held its huge head high, covered with poison spots, and the breath from its mouth turned into flames, scorching the sky.

brief introduction

Nidhogg (nidhogg) originated from Nordic mythology. It is said that there is a black dragon named nidhogg lurking at the root of the world tree leading to the country of death. It is eating the trunk with countless other snakes. When the trees are eaten up, the world will be destroyed.

Edit this legend

Nidhogg (NID· Hogg), in Nordic mythology, is a poisonous dragon lying at the bottom of the world tree (Yggdrasil), gnawing at its roots. There are many ways to write Nidhogg: Nidhogg, nidhogg, Nithhogg, nidh? gg、Nidh？ ggr、Nithh？ ggr、Nídh？ ggr、Nithhoggr、Nidhhogg、Ní？ h？ gg、Ni？ Hogg, Tony? hoggr、Nídh？ Gg, Hidhaegg or Nidhhoggr. English is: Nidhoggur. In Danish, it may mean Nidhug or Nidhog. The name means "terrible biter" and "malicious attacker". In Snorri Sturluson's essay "Deceiving Gurufi", it is mentioned that the root of the tree of the world is near the Hvergelmir Spring in Nifheim, where Nidahog desperately wants to knock it down, and many poisonous snakes are also helping him. These snakes are: Goin, Moin, Grabak, Grafvollud, Ofnir and Svafnir. When they bite off the roots of the tree of the world, the "twilight of the gods" is coming. In the poetic Eda, besides nidhogg's gnawing at the roots, there is also a feud between him and Vader fournier, the eagle at the top of the world tree, and Ratatosk the squirrel is the instigator between them. Besides, it eats the souls of the dead, who were thrown into the Hvergelmir spring after their death because of their evil deeds. When the "Twilight of the Gods" comes, it will flap its wings and fly on the battlefield full of dead bodies. Nidhogg is also one of the few creatures that survived the "Twilight of the Gods". Near Igdelasius, beside the inexhaustible spring Hvergelmir, there is a terrible dragon nidhogg gnawing at the root of the tree of life, and there are countless snakes. The names of these snakes are Goin Moin, Grabak, Grave Grafvollud, Ofnir and Swaffer. Both dragons and snakes want to kill the tree of life. When the tree of life is dead, the end of the gods will come. Ratatosk, a mischievous squirrel, kept running among the branches, telling the dragon what the goshawk at the top of the tree had seen and heard, often provoking hatred between the dragon and the eagle.
