For the entire Asgard and Odin bosses, Surtr, dark elves, and hellish demons have never been a real threat.

Surtr was once the defeated of Odin's bosses, and the dark elves were once banished into the dark airclaves by Asgard.

As for hell, Asgard itself has its own Heim underworld.

The only one who can threaten Asgard and Odin is the black dragon Nid Hogg who is constantly eating the roots of the World Tree under the World Tree.

The World Tree is the foundation of the entire Asgard, and even the entire Nine Realms, the source of life and all the power of Odin's boss are bound to the World Tree, once there is a problem with the World Tree, everything in the entire Nine Realms will come to an end.

Now, the terminal control room of the Rainbow Bridge has been recaptured, the doomsday army sacrificed by the Dark Elves has been blocked from Asgard's defenses, the Dreadlord has been killed, and the remaining Surtr and the Headless Horseman have greatly reduced the level of threat.

The main enemy that Asgard had to face was only one Black Dragon, Nid Hogg.

On the back side of Moon Mountain, the two Odin Bosses and the Ancient One Mage, like ancient statues, still stand on the vast square.

In front of the two of them, a moon well that resembled a waterhole had completely been freed from its previous dry state, and endless starlight gathered in it, forming a spring of energy with a huge pure breath.

This moon well is the core of the suppression of the black dragon Nidhogg, and the pure energy spring is the source of energy for the entire huge seal.

In the past, the Dreadlord and the Headless Horseman among the demons of hell contacted Surtr and the dark elves to attack Asgard, and the long-term battle and huge consumption restrained a large part of Asgard's energy and energy reserves, so that the spring water in the moon well that never dried up actually dried up.

In order to replenish the consumption of the spring water in the Moon Well, Odin and the Ancient One Mage had to appear on the back side of the Moon Mountain, and with their own strength, they replaced the spring water that the moon entered into it, and jointly suppressed the crazy black dragon Nighod.

The Hell Demons united with Surtr and the Dark Elves to attack Asgard, and they were instructed by the powerhouses in the Abyss Plane to take the opportunity to help the Black Dragon Nidhogg get out of trouble.

The black dragon Nidhogg was once a truly powerful and powerful existence in the abyssal plane.

At his peak, Nidhogg once ruled the eighty-eight layers of abysses in the abyss plane, with hundreds of millions of abyssal armies under his hands, and was the best at breaking through the dimensional plane and devouring the laws of the heavens and all worlds.

In a sense, the birth of the entire World Tree has a huge connection with Nidhogg.

In the years that I don't know how long ago, there was also a mad invasion of the main world of the universe in the abyssal plane.

Nidhogg, the vanguard general of the Lord of the Endless Abyss at that time, relied on his own talent to corrode and penetrate a passage between the two main worlds of the universe.

At that time, the Aesir Protoss was not yet a Protoss, but just a group of cosmic races that had just come out of the earth.

As soon as he came out of the earth, he encountered the invasion of the abyss plane, and the first god king of the Aesir god clan at that time, Buli, brought out a seed of the World Tree from the earth, and cooperated with the ancestor of the Giant Realm, the Giant Mimir, to water it with the spring of wisdom that the Giant Nation has guarded for generations, so that the seeds of the World Tree can take root and sprout, and the entire abyss passage is blocked.

With the growth of the World Tree, the endless war, Nidhogg was finally suppressed under the roots of the World Tree.

Relying on the World Tree, the Asa Protoss finally grew into the protagonist of the universe of an era, and in a long time, established the Nine Kingdoms and Asgard, and became the true overlord of the universe.

But in the same way, Nidhogg has also become a huge hidden danger to the World Tree, eating away at the root system of the World Tree all year round.

This time, the comeback of the abyss plane seized a good opportunity, the three major empires in the universe are at war, the crazy Titans slaughter the creatures of the universe, and the Celestial Group is still licking its wounds after being severely damaged by Odin, and Odin's strength is gradually aging and declining.

If you can take this opportunity to release Nidhogg and let Nidhogg devour the entire World Tree, you can make Nidhogg grow to the fourth stage, and even a higher-level powerhouse, once again penetrate the passage between the main world of the universe and the abyss plane, and swallow the entire Nine Kingdoms with one body, and then sweep the entire universe.

Originally, this plan of the Abyss and Hell Demons was very feasible.

Odin boss and the ancient mage were pinned down on the back of Moon Mountain, and the hell demons, Surtr, and dark elves were about to break Asgard's last struggle, once Asgard was broken and the Aesir gods ushered in Ragnarok, Odin's power would be weakened again, and the ancient mage alone would no longer be able to resist Nidhogg's counterattack.

However, the arrangement of fate allowed Jordani, Tony and others, with a large group of Star-Lord and Bald Don, to cross over from the huge "Demon Fart Limit" of Casa Star, and just happened to come to the Uru metal deposit area in Asgard.

Tony, who restlessly instigated Jordany, stole the precious mineral deposits of Odin's family.

At this time, Odin had a full excuse to catch Jordan and others directly to Asgard, not only took away the soul gem for the ancient boss to use, but also asked Jordan and others to work for Asgard and participate in the war.

With the Soul Gem, it will be easier for Odin and Ancient One to suppress Nidhogg, and Miss Hela and Asgard will be able to use more World Tree power.

Coupled with the variables caused by Jordani and others, the battle situation that was originally very favorable to the abyss and hell demons was directly broken in just a few days.

This time, Odin pulled Hela and Jordan to the back of Moon Mountain, in order to take this opportunity to completely clear the root of Nidhogg.

Once Nidhogg is completely clear, the whole of Asgard will never have to worry about Ragnarok in the future, and even Odin Boss will be able to use the feedback of the World Tree's recovery to return to his peak state again, enter the Heavenly Father level, and become a fixed sea god needle in Asgard for a long, long time.

In a sense, this is also an unparalleled benefit to the planet.

Although the Aesir Protoss has been separated from the earth for a long, long time now, and is known as the Cosmic Protoss, in essence, this cannot change the fact that the Aesir Protoss is a prehistoric human being.

Asgard, as the lord of the Nine Realms, as the barrier and guardian of the earth, can remain strong enough, and the earth side can also usher in a long period of peaceful development.

Of course, big harvests come with big risks.

The black dragon Nidhogg, who was once the vanguard of the Lord of the Endless Abyss, had already reached the peak limit of the Heavenly Father level before the rise of the Aesir Protoss, and could step into the fourth stage at any time.

Now, even if it is a combination of the four powerhouses of Odin, the Ancient One, Jordan and Hela, and occupying the geographical advantage of the World Tree, it is not a simple matter to deal with Nidhogg.
