Three thousand meters underground, countless caves/caverns connect a vast, deep, complex and mysterious underground world.

Countless thick mosses were attached to the rock wall, and the moss was fluorescent, bright enough for ordinary people to see the details a hundred steps away. All kinds of creatures that live underground all year round can easily see the wind and grass in a few miles. Not to mention the moss, like the trees on the ground, there are countless noctilucent plants that grow.

The tall trees are like banyan trees, hundreds of zhang high, and countless light green, dark blue, and fluorescent purple air roots hang down from the top of the cave.

Clusters of small low shrubs are clustered like mushrooms. The leaves and branches of the small shrubs are glowing, and the light fluorescence is very pleasing to the eye, and each small shrub can illuminate a radius of several feet.

There are also a large number of strange and beautiful flowers blooming in the moss. Shaped like lilies, roses, peonies, and peonies, the details are very different, and all kinds of flowers bloom, each flower exudes dazzling brilliance. Their bright color is exactly the same as the color of their petals, colorful and magnificent.

In a sea of light and a world of light, countless fluorescent insects fly freely. Some of the moths are so large that they even fly on the side. Countless points of light fell lightly on one side. The powder on the moth's body is like a meteor, like a firefly, and a large amount of light powder slowly spreads in the air, like light and fog, like a dream.

A monstrous, jackal-shaped beast scurried through the moss. It is three meters long, covered with thick black hair, with two identical animal heads side by side on its thick neck, its head is like a wolf and a dog, its sharp fangs are exposed outside its lips, and its nostrils spew out of the nostrils from time to time while running.

The beast hastily ran through the tall arbors. Running through the bushes. Stepping on the thick moss lightly crossed. The toes left countless dense glowing footprints on the ground. He even ran quickly across a shallow underground river, and countless luminous mayflies inhabited in the moss and grass on both sides of the river flew in horror, like countless elves dancing wildly on the water.

At least a million thumb-sized glow-in-the-dark mayflies flew up. The originally quiet underground river was immediately transformed into a milky way, with dazzling flames and overflowing glow.

A muscular, majestic minotaur wielding a bright, double-edged axe, galloped from behind in the darkness, and his body savagely swept through the galaxy of countless luminous mayflies. He ran at an astonishing speed, and the impact was terrifying, and the body of the luminous mayfly was fragile and pitiful, and tens of thousands of luminous mayflies immediately smashed into him. The mayfly's body exploded, countless bright saps spurted, and the minotaur's body was also stained with sap, making it particularly eye-catching in the dark.

The hunted beast is the Cerberus of Cerberus, one of the low-ranking units of the Orphe, this creature almost interprets the principle of bullying the weak and fearing the hard to the extreme, when they besiege the enemy in groups, they are extremely fierce and dare to fight the enemy for their lives; But once they are alone, or when they face opponents who are stronger than themselves, the lost dog is the best portrayal of them.

For example, the most fierce Minotaur warrior behind him, Cerberus basically doesn't even have the courage to turn back and fight.

The two underground creatures ran out of dozens of kilometers one after the other, and relatively dense vegetation had appeared in front of them, and the face of the hellhound couldn't help but show a humanized joy, such a terrain, it believed that the two-legged enemy would not be able to outrun the four-legged oneself.

The minotaur also seemed to find that the form was not good for him, and it let out an unwilling roar, and the giant axe swung up, cutting down several plants that stood in the way, but if it chased further, the trees in the way were thicker and denser, and it was impossible to open the way by brute force. Seeing that his prey was running farther and farther, the minotaur finally stopped, roared and slashed with his tomahawk a tree that was the thickness of two people hugging each other, and just now he was stuck in the middle of his run, so that he lost his track of Cerberus, so he could only vent his anger on it.

One axe, two axes, three axes...... The thick tree let out an overwhelmed moan, and finally fell down with a creak, but at the moment when the tree tilted, a figure rushed out from behind the tree like lightning, and a trace of inexplicable horror flashed in the Minotaur's eyes, but before he could react, a hand like iron pincers pinched his throat and slowly lifted his bulky body up.

"I wanted to sneak over, but I didn't expect you to hit me. It's okay, I have a few questions for you, and if you don't want to die, I hope you can answer them seriously. Shen Hao stood on the half-cut stump, raised one hand above his head, and held the minotaur who was nearly half taller than himself in his hand.

......

In the surface world, the five empires are in flames, and the war has burned half the continent, and the underground world has not been very peaceful recently. First, there was a coup d'état in the country of Ofu without warning, when three self-reliant dukes attacked the capital, overthrew the rule of Sardin III, and quickly integrated the army of the whole country, assuming a posture of foreign invasion.

As a powerful country in the underworld, Nigon was obviously affected by the achievements of its strong neighbors, and the army that had been sent to plunder the earthly world quickly withdrew to the country, and deployed 100,000 troops on the border between the two countries, and war was about to break out.

But at this moment, the captain of the Negon Limestone Guard, the promising young magician Carlody Russell, suddenly led a team to treason, and kidnapped Princess Leia, who was about to be married, and fled into the territory of Auver. The royal family of Nigon was furious and sent twelve black dragons to chase after them, but Ofu seemed to have made some kind of agreement with the traitor in private, and when the black dragons chased to Lazemir Volcano, Over's twenty archdemons collectively attacked and killed two black dragons on the spot, and the remaining ten also fled with injuries.

In this way, the two countries officially tore their faces, and a war to determine the hegemony of the underground world began. In just one month, dozens of battles took place on the border between the two countries, and two border cities on both sides were reduced to rubble in the flames of war. But both Ofer and Nigon almost mobilized the whole country this time, and although the casualties were huge, both sides refused to give up an inch of land, and the war fell into a stalemate.

After getting the information he wanted, Shen Hao pinched the neck of the minotaur. For the creatures of the Nightmare Realm that were not living souls, Shen Hao had almost no mercy.

The usurpation of the three elders of the Ten Thousand Immortal Hall was already expected by Shen Hao, these three old guys don't know how many years they have lived, they are cunning like ghosts, and their strength is unfathomable, even if they don't release the Nightmare to fight, it is not impossible to overthrow the rule of an empire when they are suddenly launched.

What surprised him was that the magician who defected from Nigon, although he also used the identity of this world, but guessed and knew that it must be Xin Suran that guy, but he would defect to the three elders of the Ten Thousand Immortals Palace, which proved that he also retained the memories of the past, which made Shen Hao a little surprised, if the magician had any means to resist the bewitchment of the Nightmare Realm, then Mo Chenyan who was with him should also be able to stay clear, but in fact, Mo Chenyan, who was incarnated as Princess Leia, definitely did not recover his memory, Otherwise, there would be no need for Xin Suran to kidnap him.

"Hehe, this guy really has a ......" Shen Hao swept the double-edged battle axe he snatched from the Minotaur, this weapon was made of Noken metal unique to the underworld. Although the craftsmanship is relatively rough, the weight and sturdiness are not possessed by Erathia standard equipment. In particular, the sharp blade of the axe shimmered with a rare faint red glow, which was due to the elemental effect of the fire attribute of Nokon metal.

Xin Suran's actions brought a little surprise to Shen Hao, in the current situation, one more help will have one more chance of winning, and now that they have been gathered together in advance, and have an empire as a team, then the next thing will be much more convenient.

The Underground World is not as complex as the Overland World, it is only divided into two areas, the Molten Zone and the Dark Rock Zone, of which the Olver is located is the Molten Zone, where the Underground/Volcano converges, and there are lava rivers everywhere, except for a few special creatures such as fish in water, which are not suitable for most creatures.

And the place where Shen Hao came down this time belongs to the Dark Rock District, which is the territory of Nigon. Although there is no sunlight on the ground, there is a complete ecosystem. There are rocky mountains, underground rivers, plants and animals, and many luminescent creatures inhabiting it, making it not very different from the surface world.

It is rumored that Nigon was originally a tribe of the earthly race, but was defeated in a world war tens of thousands of years ago and driven to the dark underground. However, the top leaders of Nigon have always had the idea of returning to the surface, which is why they always form a small raiding team with nearly half of the army, and from time to time they will kill the surface from various underground passages, harassing and plundering those rich countries.

Although Aufer and Nigon belong to the same underground realm, they have been safe and sound for thousands of years, which is actually very related to their previous survival habits. The creatures of Ofer only like fiery molten slurry, and that kind of place is absolutely unsightly, except for the availability of some rare minerals, it is not worth waging war at all, so there has been no conflict of interest between the two sides before, and they have never regarded each other as enemies.

But this time it was Ofer who started the war first, and the leadership of Nigon did not understand whether they were for the sake of plundering resources or the unrealistic ambitions of some people, but the kidnapping of the princess of their own country, coupled with the loss of two dead and ten wounded of the noble black dragon clan, had seriously hurt Nigon's dignity, and such a shame could only be washed away with the blood of the enemy.

Shen Hao cautiously marched all the way to the south, and everywhere he could see the build-up of Nigon's army. And in it, Shen Hao discovered one of the intelligent races of the Nigon high-level - the dark elves.
