The Abyss Realm, the border area of human power, was once over the nest of the bald eagle.

The majestic aura of flames spread, and the red dragons were neatly suspended in the sky, looking down at the ruins that had long been beaten into a big pit by the shocking battle between Mei Xue and Breaking Wind.

"It's a pity that I'm a step too late." The Black Dragon Emperor Ji frowned, the reason why she could rush to Moonfall Village faster than any of the big forces in the Abyss Realm was precisely because of the changes that had taken place here.

On the ground, more than a dozen Heaven Domain-level immortal warlocks joined forces and almost found everything suspicious in this mountain range.

Some transparent blue shards, a few tainted leyline gems, these things may seem all too common in the eyes of others, but in the eyes of the Black Dragon Emperor who has been tracking a certain creature, these things are decisive evidence.

"Sure enough, it's that guy, it looks like it's been resurrected." Looking at the light blue fragments in her snow-white palm, the Black Dragon Emperor Ji pinched it hard, and then pinched and exploded these fragments that had been polluted by the power of the Nine Shadows.

"It's troublesome now, sure enough, the upper-rank Nine Shadows Race is not so easy to defeat, and it's only been a few years, has it recovered to the point where it can create descendants?"

"Worthy of ...... Blue Moon. "Most of the blood-colored dragoons who followed the Black Dragon Emperor to this border area had very bad faces.

"Blue Moon" is the code name of the high-ranking Nine Shadows that once tried to invade Dragon Palace City, and was finally repelled by the Black Dragon Emperor Ji with "Silver Dragon Dawn".

Its main body, when it invaded Dragon Palace City, was a huge polyhedral shape, and the outer layer of defense alone ignored all human Heaven Realm level attacks, and those who could leave scars under that transparent shell were all famous Divine Soldier Rank City Lords in the Abyss Realm.

That battle was the most shocking battle since the establishment of Dragon Palace City in the Abyss Realm, and it was this battle that made the Black Dragon Emperor Ji a well-deserved Divine Domain Rank strongest in the Abyss Realm.

Since the movement speed of this Upper Nine Shadows Species was not fast, the human forces knew its movement route as early as three months ago, and specially arranged a super defense line in front of Dragon Palace City.

The two major camps of the human forces in the Abyss Realm, the Heavenly Kingdom Faction and the Earth Abyss Sect rarely joined forces, and even some ancient God-level creatures who had a good relationship with humans also participated in this battle.

When the Upper Nine Shadows, codenamed "Blue Moon", appeared in front of everyone, the huge size that seemed to cover the sky, and the terrifying power that distorted the void just by moving made everyone feel the horror of the Upper Nine Shadows.

It was a creature that was completely different from the mid-rank Nine Shadows that occasionally appeared in the Abyss Realm, and the human race gathered the power of several Divine Soldier Rank City Lords to hope to repel it.

The Nine Shadows of the Upper Rank, with its transparent and soft blue luster, the strange phenomenon of constantly changing the texture of the shell with the laws of mystery, and the huge size of more than tens of kilometers, are an incredibly beautiful creature that cannot be reached by humans.

From the indescribable horror to the shocking, god-like incarnation like the embodiment of rules, it is the dividing line between the middle and the top.

The Nine Shadows that have evolved to the upper level have brought people not only earth-shaking changes in appearance, but also oppression that shocks the soul.

Unlike the lower rank and the median nine ghosts, which will take the initiative to attack and devour countless living beings, this upper nine shadows codenamed "Blue Moon" does not seem to have an obsession with a simple life goal.

It's just a city that is unwavering and unwavering in its approach to humanity, and it does just one thing.

The sheer size of those tens of kilometers, and the huge twisted fields scattered around it, were in themselves the most terrifying natural disasters for humans.

In the records of the Abyss Realm, this Upper Nine Shadows Species, whose real name is unknown, is called the "Blue Moon" by the Abyss Realm, and every time it appears, it will destroy more than ten or more human main cities.

And the human race's record against the "Blue Moon" is a complete defeat, let alone resisting this high-ranking Nine Shadows, and it can't even make it change its trajectory.

When the Blue Moon first appeared, it was a time when human immortal warlocks were massively expanding the abyssal realm, and the great supernatural powers and immortal warlocks were still fully cooperating.

At that time, the human race did its best to cast seven main cities connected by huge formations, and proudly called these seven cities the invincible absolute fortress and named it "Tianxin Seven Cities"

With the help of the countless rare resources of the Abyss Realm, the Heavenly Realm Rank Immortal Warlocks suspended all the seven cities of Tianxin into the sky, announcing the arrival of human beings to the Abyss Realm.

This kind of arrogance and arrogance did not know how terrifying it was until the appearance of the Blue Moon, and even discovered that the Blue Moon had a crazy capture plan to try to dissect the mysterious structure of this behemoth.

Then, they failed.

Blue Moon curiously approached the seven main cities of the human race, and smashed the seven sky cities with a completely crushing attitude, completely crushing and shattering the pride and confidence of the immortal warlocks who were high above.

All the attacks of the Human Immortal Warlock Alliance did not even break the shell of the Blue Moon, and they could only watch as the Blue Moon slowly disappeared at the end of the horizon after smashing the seven Sky Cities.

The code name of "Blue Moon" is the honorific title of this unknown high-ranking Nine Shadows by the Heavenly Realm Rank Immortal Warlocks at the apex of the human race, and humans and the Nine Shadows cannot communicate, so humans cannot understand the laws of action of the Nine Shadows, let alone know their real names.

In the past few eras, the Blue Moon would always appear in the human territory by extreme "accidentality", destroying several human main cities each time and then disappearing.

The "dark sun" in the sky and the "blue moon" on the ground have since become the nightmare of the Heavenly Realm Rank Immortal Warlock.

Compared to the dark sun that is always high above and never interferes with the ground of the Abyssal Realm, this Blue Moon, which only occasionally wanders in the Abyss Realm and triggers a catastrophe of destruction just by passing through the human area, is the real henchman of the human race.

Therefore, in that battle, the fact that Blue Moon, which had crushed the human forces as in the past, reappeared, but was finally repulsed, shocked the entire human forces in the Abyss Realm.

The Black Dragon Emperor Ji, this name, also became the undisputed number one powerhouse of the God Domain Rank in the Abyss Realm from that time.

Some people even thought that her strength might be close to that of the Lord of the Four Extremities of the Abyss Realm, and she was the only one among all the Divine Realm Ranks who was considered to have the greatest hope for the future Advanced Tribulation Breaking Period.

However, what few people know is that the war is not over, and it can even be said that it has been continuing.

Outside the Dragon Palace City, the Blue Moon, which was repelled by the Black Dragon Emperor Ji with the Silver Dragon Dawn and whose shell was broken, did not disappear like the past few times.

The battle between this terrifying Upper Nine Shadows Species and the Black Dragon Emperor, the first powerhouse of the Earth Abyss Realm, has continued from that time to the present.
