The two sides are fiercely attacking, and the fighting is bloody and flesh is flying. When there was no way out, Sen Wolf and others also took out the last old bottom, united as one, and frantically resisted.

Although Mai Xuela, Li Tang and others were brave, they couldn't eat it in one go.

But the demise of Sen Wolf and others is only a matter of time.

Using the Golden Elf Week, the task of collecting troops with diplomacy was handed over to Elizabeth, Yilin and Xiaolongnu, the three daughters cooperated tacitly, Yilin returned to the city to teleport, Xiaolongnu's logistics skills accelerated, Elizabeth was responsible for negotiations, and the number of golden elves increased terrifyingly.

As for Adela's main quest, he can't participate in it for the time being because he has not yet completed the unification of the Tang Dynasty.

So what should Du pre do?

For a while, Du Pre, who had divided all the tasks, became a hands-off shopkeeper and had nothing to do.

This is extremely rare in the Scarlet City Gate.

Du pre-chose to lead the troops out of the city and continue the adventure.

He doesn't go far from Swallow Dock, he ventures around.

His current melee strength is flawless, but in terms of magic, he also needs to be trained.

There is only one magic-type hero, Yilin, who is acceptable in the early stage, but will gradually be insufficient in the later stage.

Du pre-led his army out of the city, preparing to go to MF, and by the way, visit some facilities to increase intelligence and strength.

One of his main goals is to find the Blade of Doom.

This thing is not only a key prop that can be cleared, but also a treasure that An Huaqing pointed out. You must know that Sumeru mustard seeds can make the swallow dock bigger and smaller at will, forming a fortress that can be summoned at any time, and Du Yu must keep it in his hands.

But in the thieves' union, after a long time of investigation, coupled with the investigation of McSherra's intelligence network and various lieutenants, let alone finding the Doomsday Blade, I have never heard of it.

Du Yu had no choice but to go into battle by himself and concentrate on searching.

But the dwarven undead king in the gold mines. Someone was summoned to summon him.

Their old enemy, Roghardt, died tragically at the hands of Du Pre, and he was grateful to Du Pre, and during this period of time, 2,000 gold coins were produced every day. Supplies to Du Pre military supplies.

"What is the matter with this undead king?" Du was curious.

"Hero, we live deep underground, mining day and night, but underground, we hear some noises." The dwarven king undead whined.

Du Yu gradually became curious.

"Underground? Why is there a sound? Du Zhen frowned.

"Heroes can go down to the mine with me, and we'll survey together." The dwarven king is undead, pointing to the mine cave.

Du Yu nodded. With the army, slowly enter.

It was so close to the Swallow Dock that even if the demon army came, he would have time to return.

The scale of this gold mine is so large that it is no wonder that it can produce twice as many gold coins per day.

The speed of Du Pre's development is also beyond his imagination. At this time, his financial resources, in addition to the artifact and the main city, are more than half. Rely on donations from the Wolf Pupil Alliance.

The vast Oriental Elven Forest has almost become a colony of Du Yu alone. An adventurer who has gained a stable development environment. He is very happy to pay a part of the protection fee per day for the use of the boss Du Pre.

Anyway, Du Pre is located on the border line, and his strength has increased, which is beneficial and harmless to resist the invasion of the Hell Clan.

As he continued to deepen, Du Yu's face gradually became serious.

Because. The gold mine seems to be endless, all the way down.

Will it lead to underground space?

What is this strange sound underground?

The Dwarven King Undead said slowly, "Recently, our excavation progress has been very fast, and we have almost opened up several major veins underground. But a cave was also dug up. ”

Du Zhen finally came to the end of the mine.

A cave opening, appearing in the black-brown rock at the end, and a cold wind blows strongly from the hole.

"This is ???"

"It leads to another cave, but I've lived for hundreds of years and I've never heard of a dwarf digging here." The ghost of the dying dwarven king is very sure.

Since it is not the dwarves who dig the hole, where does this cave come from?

Du pre-drew his divine shotgun and slowly climbed into the cave.

It's a strange world.

The underground, emitting the fluorescence of minerals, makes the sight not as dark as imagined, and you can't see your fingers. The general outline of the cave is faintly visible???

There is an underground river underground, running slowly, and there are fish in the water that emit white light and phosphorescence, swimming around without eyes.

In the air, in addition to the humidity, there is no dull and rancid smell as expected, but there is a slight wind flowing, and it seems that there are entrances and exits on both sides of this underground passage, and the terrain is vast.

Underground plants are very abundant, in addition to mosses, underground ferns, and mushrooms all grow in the dark river, swaying slightly in the breeze, emitting a trace of fluorescence.

With such abundant plants, there is naturally no shortage of underground animals that come to feed.

A group of blind-eyed, long-nosed, hoofed-footed earth rock monsters are feasting on silver-white mushroom rings, and from time to time they make a humming sound similar to that of a wild boar arching the earth.

Groundhogs and wild mice, which also haunt the underground fern jungle, have deteriorated eyesight and perceive more acutely.

"This ???" Du Zhen was amazed.

"THIS IS THE UNDERWORLD" Serena the vampire's eyes flashed red, undisturbed by the dim vision. The vampire's night vision guarantees that this will become Serena's familiar home turf.

"Quiet! Listen! Du pre-internal force is strong, his ear power is very sharp, and he waved his hand.

The army, which did not come out, suddenly stopped, and then listened.

In a cave in the distance, the rock gradually widens into a huge tunnel, large enough for hundreds of people to pass side by side.

Du Pre, the Dwarven Undead King, and Serena glanced at each other, and the three of them slowly walked into the shadow of the rock pillar, observing the scene in the cave.

It was a spectacular sight.

Hundreds, green-skinned, and about a meter tall cavemen march silently under the command of the red-skinned Hellcavemen, who have no sight but are agile in the underworld, as if they have invisible sentience, allowing them to pinpoint their targets. The Cavemen live near low-lying water, and only work when they are forced to do so. They don't have eyes and rely on infrared sensing to survey their surroundings, so blindness and petrification in status magic don't work against them. Since there are a lot of numbers, it is generally won by quantity.

The cold and sharp spears in their hands showed that this army did not come for peaceful purposes.

What's even more terrifying is the terrifying monsters that follow.

These monsters flew in the air, with the upper body of a beautiful woman, their faces were quite enchanting, and their chests were even more choppy, and some male animals that could be seen couldn't take their eyes off it.

But the lower half of their body is the thick claws of a bird, with two wings on their backs.

This is the Ornikan and the advanced class HarpyHag.

These half-human, half-bird bird-like banshees attack in a very strange way, pounce on enemies to attack, and then retreat back to where she was before attacking. Like her, the Birdbox Witch attacks with a pounce, but the Birdbox Witch does not retaliate after attacking, which is very effective against slow classes. If you're slower than the Ornithic Witch, you're unfortunate enough to be wiped out without even touching it.

For the time being, there are no other higher classes, but these hundreds of blind people and bird-body witches are enough for Du to predict their identities!

"The Gongen of the Dungeon!" Du pre-gritted his teeth.

"The Scarlet Gate made it clear from the beginning that this time the adventurers were facing a double attack of hell and dungeon. But our eyes have been staring at the demons on the ground, but we didn't expect that Gonggen underground is also actively acting. ”

Serena also had a grim face.

This Gonggen people, in the underground world, are equivalent to the overlords in general. Their city is located in the middle of the Underworld, but the Gongen people gain attack, defense, and speed buffs in the Underworld. Other races, however, will be harmed.

As soon as it comes and goes, the gap is huge.

"The strange sound that the undead heard when they were mining must have been made by the Gonggen army when they were marching." Du pre-made a bold guess.

The Undead King nodded: "We have only recently hollowed out the bottom of the mine and inadvertently opened this passage???"

"Thanks to you for getting through here" Du Yu looked at the mighty and constantly surging Gonggen army, and his eyes were cold: "Otherwise, we don't know how to die." ”

"But the adventurers didn't fail to notice Gonggen," Wang Yuyan said calmly, "In fact, at the beginning of the opening of the Scarlet Gate, the adventurers were frantically exploring the map. Recently, we have basically unified the Elven Forest, and gradually drawn a more detailed military map. At least from the terrain you have mastered, you haven't found a passage from the underground world to the surface world? ”

Du Yu nodded: "But we rely too much on the experience of the game. You know, this is the Scarlet Gate, not the game world! Look at what the cavemen have in their hands. ”

Wang Yuyan looked at it fixedly and couldn't help but be taken aback.

In addition to the commonly used spears, these terrifying cavemen also have digging tools such as hammers and shovels similar to those used by dwarves when mining.

Even those bird-body witches have an important mission.

It is to use the terrifying flight speed to explore the path to the surface world in the maze of hundreds of caves in the underground world.

Even if you can't find a ready-made road, find the weakest part of the rock formation.

Then summon the cavemen coolies and start building the road.

"They're going to ???"

"That's right, the Scarlet City Gate is closed, and the difficulty is really perverted!" Du said coldly: "The forces here are all living intelligent creatures. They will take timely measures within the limits of intelligence and capabilities to ensure their victory. So, on the surface of the Hell, while attracting our attention. The Gongen people are expanding into the underworld, building underground passages to various realms. Prepare to cooperate with the Hell Clan for a large-scale sneak attack in the future.
