At the most dangerous moment of the human race, the Cardinal found clues of the Supreme Temple after careful research, and guided Anakin to pass the assessment and obtained one Supreme Angel every week.

With the help of this amazing level 8 soldier, Anakin barely defended the defense line after several character explosions.

Yakun in the north, after being completely destroyed by Du Yu, lost the power of the Dragon King, returned to the main city, and began to develop again. The Gonggen people tried to expand the results of the battle and were defeated by Yakun.

On both fronts, the Gonggen people could not make progress. But at present, the strongest person on the mainland is still Gonggen.

When the demon army advanced to a huge cave hall, Names respectfully said in front of Du Yu: "Commander, we are here!"

Du Yu raised his head and was shocked by the scene in front of him.

What a big hole!

At least hundreds of meters high, the faint sunlight casts mottled light and shadow through the holes on the top, making it not too wet.

A towering cannot describe its height, and a grandeur cannot describe its scale.

The width has reached hundreds of kilometers. Anyway, Du Yu looked far away and could not see the edges and rocks.

In this cave, there is an underground river flowing slowly

Lush moss and mushrooms grow on both sides of the underground river.

Tens of thousands of cavemen and hell cavemen are working hard among mushrooms.

The bird demons gathered at the top of the dark cave, giggled, staring at the every move of all creatures on the plain. They were the eyeliner of the Dragon Queen Jasper.

The earth and rock beasts controlled by the Evil Eye are eating grass on the grassland - they are the source of carnivorous food for black dragons and higher creatures. These wild beasts that are tamed by the Evil Eye spirit have become existences similar to human domestic animals.

More humans, elves, barbarians and dwarves who were attacked and plundered by the dungeon tribes countless times worked hard, planted, collected and built underground, and magnificent castles rose from the ground in the vast caves, with the city walls and dragon caves shining with a dark luster.

This is what makes all ethnic groups in the mainland shudder. The most powerful country in the world is the Dungeon Empire.

The Dragon Queen Moriel is ruthlessly ruling the world.

Plunder and whip are the roots of the continuous power of this empire.

"Hmm? Our allies. Haven't received a letter from my visit?" Du Yu found that there were no messengers from the Gonggen people until now, and his face turned gloomy.

Names hurriedly replied, "The letter has been sent out long ago. I don't know why."

As she was talking, a dazzling magic light suddenly rose in front of her eyes!

After the beam of light disappeared, a female magician with black hair, deep eyes and a scarf walked out.

She looked arrogant, and only when she saw Sellen (Du Yu) holding the Hellfire Sword, she felt awe. She lowered her head and retracted: "Welcome! The great devil commander. I am Saferoth, representing my emperor - the great queen of the dragon, Jalier, welcome your arrival."

Du Yu smiled slightly, and it was a politeness. Names, who was eager to show off, hurriedly introduced in the commander's ear: "Hehe, this lovely person is one of the few female magicians who serve in the Gongen Empire. She originally claimed to be the illegitimate daughter of the previous generation of Erasia. One day she wanted to be claimed and gain the status of the lord. However, she was rejected, which aroused her strong hatred for Erasia. She became a magician and defected to Gongen."

As an envoy, Saferos simply welcomed him and frowned and looked at the army of demons.

"Sorry, the Demon Commander, although it is a bit rude, you know that the demon army cannot enter the Black Cave City, the capital of my empire. Therefore, "Saferos looked proud: "Please stay here. You and your entourage can enter."

Names's face darkened and he growled, "Saferos, what do you mean? Not long ago, our commander had just come to Black Cave City to negotiate the alliance attack with Queen Moriel. You don't have this rule!"

Saferos smiled contemptuously: "Yes, the commander did get extra care from the Queen last time. But once and forth, we Gonggen army occupied no less than thirty enemies in the West and the North. And what about you? You were defeated by the elves and lost more than 150 cities. I am sorry to both sides that you can continue to be our allies, which is the gift of Her Majesty the Dragon Queen."

Names roared: "Saferos! Is this your hospitality as an envoy? Do you dare to openly insult our army of demons?"

Du Yu stopped Names's rage and growled: "I represent the great Emperor Lucifer Kregan, and I have something important to talk with His Majesty the Queen of the Dragon. If you have this attitude, I will leave immediately. I hope you can bear this loss and consequences."

Saferos hesitated.

To be honest, although the number of demon troops is quite large, especially the 60,000 long-horned demons, it is fearful. But where is this place?

It is the capital of Gonggen, Heizui City!

Like the Demon Guards Legion, the Gonggens also placed the Dragon Guards Legion in the capital to support them. The strength of the Demon Army is not worth mentioning in front of the Dragon Guards Legion!

Before she came, Empress Malile certainly did not want the devil troops to enter the city to give instructions. The Queen was too lazy to talk about this little thing.

In other words, this is simply that Saferos, representing the Gongens, gave the demons a warning, without the empress' authorization.

If there is a fall in love with Sellen because of this and the incident is exposed to Malile, Saferos is afraid that he will not be able to withstand it.

She bit her lower lip angrily: "Okay! I allow you to lead troops into the city. But remember, the Dragon Guards Army will closely monitor your every move. As long as there is a strange movement, the hungry black dragons will get rich demonic flesh."

After she finished speaking, she took the lead in walking forward angrily.

Du Yu felt a little amused.

It is said that the demon and the Gonggen people wear a pair of pants.

It seems that as the war progresses, the evil allies who were originally treated equally began to have a rift due to their strength.

Should I expand this rift by myself?

Du Yu, who was on a visit as the emperor's special envoy, touched his chin with interest.

If that's the case, maybe

The Heizui City is located in the center of the vast underground cave. After walking for half a day, everyone saw the magnificent city wall.

When he got closer, Du Yu was even more surprised.

This Gonggen people deserve to be a super power that dominates the entire underground world.

The city walls of Heizui City are tall and thick. Just looking at the city walls made of obsidian without hesitation of manpower and material resources, it feels indestructible!

Outside the city wall, the Gonggen people used a large number of slaves to attract asphalt poison springs, which were bubbling with black poison spring water. Once the invaders stepped in, they would suffer heavy casualties.

On the city wall, there are towering arrow towers every dozens of meters, and countless evil eyes patrol and walk around. As long as they find slaves escaping or enemies invading, their terrible dead rays will be concentrated at the first time.

In the face of such a intensive and deadly defense, even if his Golden Dragon Army came in the air, he might not be able to conquer it quickly.

The only entrance to the entire Black Cave City is in these tall and thick city walls, the rolling black water moat, the terrifying arrow tower, tens of thousands of evil eyes, and the scorpion lions and bird-body banshee's eyelids that are constantly passing through the sky. A narrow passage allows only four people to come in at the same time.

The demons suddenly changed their color.

In this case, once the Gonggen people suddenly attack, this demon army with a number of 100,000 will be wiped out.

When Saferos looked at the magnificent and strict defense of the Black Cave City, the demons' faces turned pale and their colors changed. The breath that was being held in their hearts finally came to relax, giggled, and took the initiative to introduce them.

"Dear allies, when you come to my Heizui City, the most worthy view is"

"Dark Dragon's Cave!"

As the magician pointed his finger, the demons looked at the northern part of the Black Cave City, the most terrifying platform!

This Gonggen army is also known as "Dragon Army"!

Although there is no lack of self-praise, the Gonggen people have jumped from a weak race to a superpower with a change of color on the mainland, relying on a kind of power.

Black Dragon!

A terrifying dragon expelled by his fellows on the ground and threw himself into the darkness.

They are the strongest dragons, stronger than the elves' golden dragons.

Above the Heizui City, hundreds of meters high, there is a dark cave!

It seemed that no light could penetrate the cave, just like a black hole in the universe, so dark that it was impossible to see your five fingers!

But the reason why everyone can see some dim scenes is due to the dark platform being covered with golden mountains of gold!

There are countless gold, silver and treasures shining on it, and the light of precious treasures is many of them that are first and second-level treasures that mainland adventurers are rushing towards!

It is extremely precious and hard to find treasure, which was used by the Gonggen people as a nesting object for the dragon's nest.

Du Yu suddenly understood why such rare treasures as sulfur armor were also put into the dragon's den by the Gonggen people as sacrifices to the black dragons, and accompanied the black dragon.

Needless to say, the dragon nest in this Black Cave City must be inhabited by the dungeon world. The number of black dragons with the largest number is definitely a state secret, and Saferos will never say it.

But it will definitely not be less.

Du Yu knew that the Demon Guards Army stationed in Seergon had a number of great demons, about 7,000. Last time the fierce battle at sea, he killed 3,500.

Since the Gonggen people have 400 cities like the demons, the number of black dragons in their capital, Black Cave City, will not be lower than this number.

7,000 most powerful black dragons guarding sulfur armor.

Du Yu took a deep breath and smiled bitterly.

It seems that it won't work.

Then there is only one way to go.

Steal! (To be continued...)
