Both sides were attacking fiercely, fighting with flesh and blood. With no way out, Senlang and others also showed their last legacy, united and resisted frantically.

Although Mai Xuela, Li Tang and others were brave, they could not eat it in one breath.

But it is only a matter of time before the demise of Senlang and others.

The task of using the Golden Elf Week to collect troops was handed over to Elizabeth, Yilin and Xiaolongnu. The three girls cooperated with each other. Yilin returned to the city and teleported, Xiaolongnu's logistics skills accelerated, Elizabeth was responsible for the negotiation, and the number of golden elfs increased terrifyingly.

As for Adra's main mission, he is temporarily unable to participate since the Tang Dynasty has not been completed.

So what should Du Yu do?

For a moment, Du Yu, who had all the tasks assigned, became the boss and had nothing to do.

This is extremely rare in the Blood-colored City Gate.

Du Yu chose to lead troops out of the city and continue to take risks.

He was not far away from Yanziwu, but he was taking risks around him.

His current melee strength is flawless, but he also needs training in magic.

Only Yi Lin is a magic hero. It is still acceptable in the early stage, but it will gradually become less than enough in the later stage.

Du Yu led his army out of the city and prepared to go to MF, and by the way, he visited some facilities to increase intelligence and strength.

One of his more important goals is to find the Blade of Doomsday.

This thing is not only a key prop that can pass the level, but also a treasure that An Huaqing pointed out. You should 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 thief union, I spent a long time investigating, and with Maisha's intelligence network and the investigation of various deputy generals, I have never even heard of it.

Du Yu had no choice but to go on the battlefield and search for it in person.

But the dwarf undead king in the gold mine sent someone to send a message.

Their nemesis, Roghart, died tragically at the hands of Du Yu. He was revenge and was extremely grateful to Du Yu. During this period, he produced 2,000 gold coins every day to supply Du Yu's military supplies.

"What's wrong with this undead king?" Du Yu was very curious.

"Hero, we live deep underground, mining day and night, but we hear some noises underground." The dwarf king's undead whimpered.

Du Yu gradually became curious.

"Downward? Why are there any sound?" Du Yu frowned.

"Heroes can go to the mine with me, and we will investigate together." The dwarf king's undead pointed to the mine cave.

Du Yu nodded and slowly entered with his army.

This place is very close to Yanziwu, and even if the demon army arrives, he has time to return.

This gold mine is extremely large in scale, no wonder it can double the daily gold coins.

Du Yu's development speed was beyond his imagination. At this time, his source of income was more than half of his money, except for the artifacts and the main city. He relied on the donation of the Wolf Pupil Alliance.

The vast oriental elves forest almost became a colony of Du Yu. Adventurers who obtained a stable development environment were very happy to pay a part of the protection fee each person every day for the use of Du Yu.

Anyway, Du Yu is on the border line, and his strength is enhanced, which is beneficial and harmless to resisting the invasion of the Hell Clan.

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

Because. This gold mine seems endless and keeps going down.

Will it lead to underground space?

What is the strange sound underground?

The dwarf king undead slowly said: "Recently, our excavation has been very fast, almost opening up several major underground veins. But a cave has also been dug up."

Du Yu finally reached the end of the mine.

A hole appeared in the dark brown rock at the end, and the cold wind blew strongly out of the hole.

"here it is"

"The leads to another cave, but I have lived for hundreds of years and have never heard of a dwarf digging here." The old dwarf king undead was very sure.

Since it is not a dwarf digging a hole, where does this cave come from?

Du Yu pulled out the sacred shotgun and slowly crawled into the cave.

This is a strange world.

The underground emits mineral fluorescence, making the sight line not as dark as imagined, and you can't see your five fingers. The general outline of the cave is vaguely visible.

There is an underground river flowing slowly. There are fish emitting white phosphorescence in the water, without eyes, swimming around.

In the air, except for the humidity, there is no dullness and rottenness as expected, but it is slightly windy. It seems that there are entrances and exits on both sides of the underground passage, and the landform is vast.

Underground plants are very abundant. In addition to mosses, underground ferns and mushrooms all grow in the underground rivers, slightly twitching in the breeze, emitting a slight fluorescence.

Such a rich plant, there are naturally many underground animals to come to eat.

A group of blind-eyed, long-nosed, and hoof-footed earth monsters were feasting in the silver-white mushroom ring, making hums like wild boars arching soil from time to time.

Groundhogs and wild rats also appear in the underground fern jungle. Of course, their vision has all deteriorated, but their perception has become more acute.

"This" Du Yu was greatly surprised.

"This is the Underworld" Vampire Serena's beautiful eyes flashed red, and she was not disturbed by the dim sight. The vampire's night vision ability ensures that this place will become the home court that Serena is familiar with.

"Quiet! Listen!" Du Yu had strong internal strength and sharp ears, and waved his hand.

The army that had not come out stopped immediately and listened.

In a cave in the distance, the rocks gradually widened and turned into a huge corridor, enough for hundreds of people to pass side by side.

Du Yu, the dwarf undead king and Serena looked at each other, and the three of them slowly walked into the shadow of the rock pillar to observe the scene in the cave.

It was an extremely spectacular scene.

Hundreds of cavemen with green skin and about one meter tall (heroes invincible three commonly known as blind men) are marching silently under the command of the red-skinned Hell Cavemen. They have no vision, but they can act quickly in the underground world, as if they have invisible perception, allowing them to find their target accurately. The cavemen live on the edge of low-lying water and only work if they are forced. They have no eyes and rely on infrared sensing to survey the surrounding environment, so blindness and petrification in state magic are ineffective against them. Because of the large number, they usually win by quantity.

The sharp spears shining with cold light in their hands show that this army was not for the purpose of peace.

What's even more terrifying is some of the horrifying monsters that followed.

These monsters were flying in the air, with the beauty's upper body wide open, with a charming appearance and a turbulent chest. Some male animals that could see were blinded.

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

This is the bird-body banshee and the advanced military breed bird-body witch (harpyhag).

The attack method of these half-human and half-bird bird-body banshee is very strange. She will pounce on the enemy and then retreat to the position in front of her attack. Like her, the attack method of the bird-body witch is also a slap, but the bird-body witch will not be counterattacked after attacking. This feature is very effective for dealing with slow-speed troops. If your speed is lower than the bird-body witch, then unfortunately, you may be completely destroyed without touching it.

No other higher troops have appeared for the time being, but these hundreds of blind men and bird-body witches are enough to let Du Yu determine their identities!

"The Gonggen people in the dungeon!" Du Yu gritted his teeth.

"The Bloody City Gate was closed from the beginning and it was clear that this time the adventurers were facing the two attacks of hell and dungeon. But our eyes were always staring at the demons on the ground, but we didn't expect that Gonggen from the underground was also actively taking action."

Serena also had a cold face.

The Gonggen people, in the underground world, existed as a hegemon. Their cities are located in the center of the underground world, but the Gonggen people can gain attack, defense and speed gains in the underground world. Other races will be damaged.

As we go, the gap is huge.

"The strange sounds heard by the undead while mining must be made by the Gonggen army during the march." Du Yu boldly guessed.

The undead king nodded: "We have just dug out the bottom of the mine recently and accidentally opened this passage."

"Thanks to you who have opened this place." Du Yu looked at the mighty and continuous rushing Gonggen army, his eyes turned cold: "Otherwise, we don't know how we die."

"But the adventurers did not fail to notice Gonggen," Wang Yuyan said calmly: "In fact, at the beginning of the opening of the Blood City Gate, the adventurers were exploring the map crazily. Recently, we basically unified the Elf Forest and gradually drew more detailed military maps. At least from the terrain we mastered, we did not find the channel from the underground world to the ground world?"

Du Yu nodded: "But we rely too much on the experience of the game. You know, this is the Blood City Gate, not the game world! Look at the things in the hands of those cavemen."

Wang Yuyan looked closely and couldn't help but be surprised.

In addition to the commonly used spears, these terrifying cave people also have digging tools such as hammers, shovels and other digging tools when digging.

Even those bird-body witches shoulder important missions.

It is to use its terrifying flight speed to explore the path to the ground world in hundreds of cave mazes in the underground world.

Even if you can't find the ready-made road, you have to find the weakest place in the rock formation.

Then he summoned the caveman, coolie, and began to build the road.

"They intend"

"Yes, the Blood-colored City Gate is indeed abnormal!" Du Yuchi said coldly: "The forces here are all living intelligent creatures. They will take all measures in a timely manner within the scope of intelligence and capabilities to ensure their victory. Therefore, on the surface of the Hell Clan, while attracting our attention, the Gonggen people are expanding heavily in the underground world and building underground passages to various countries. They are preparing to cooperate with the Hell Clan to carry out large-scale sneak attacks in the future." (To be continued...)
