This underground city is more of an underground warehouse than a city.

Because there are a lot of monsters wandering between the ruins, they can only rely on the two remotes of Lu Niang Mei and Taishou Yilin to clear the road first, and then everyone finds a rope and lands.

Surrounded by monsters like the Lost.

Fortunately, the lost are different from the undead, the undead have the identification with their companions, if the undead next to them are attacked, the surrounding undead will be crazy because their companions are attacked, this is also the power of the undead, and the number of undead who see it dare not provoke at all.

And these Lost are outright walking dead, and they will only attack when they come up to them, and the Lost in the distance will not rush at them because their companions are attacked.

This is good news, at least it means that as long as they walk in a proper manner, they are generally not afraid of being surrounded and beaten in groups, just from a look, there are at least four or five hundred lost people in the ruins below, if they are beaten by the group, even Gu Feng can't bear it.

After that, everyone found a rope and lowered it, but when they actually got to the bottom, Gu Feng found that something was wrong, these ruins and broken walls were very well planned, and more things were a lot of rotten wooden boxes, which seemed to be for storing materials.

"It's like a warehouse." At this time, He Qingyu also discovered that there were not only ruins and broken walls around, but also many corroded armor and weapons hidden in the dust, and if they were well preserved, it would be a complete arsenal.

It's like a military base, and then look at the Lost around you, they're transformed and well-organized, they look just like humans, and it's very likely that they were humans before they were lost.

Gu Feng's heartbeat accelerated, he had only seen the Lost in one place, that is, outside the entrance of the underground world, and there were so many Lost here, could it be ......

He Qingyu obviously also thought of this possibility, and she nodded to Gu Feng: "Be careful, let the dragon walk in front." ”

The red dragon flies at the front of the team, as it can illuminate the surroundings with fireballs. The levitating light can glow, but it's too wide for the levitating light to illuminate too far in the open terrain.

Everyone moved forward cautiously, constantly knocking down all kinds of lost people.

They were looking for a way to see if there were any other roads, but Gu Feng was most worried, if there was really a gate to other worlds here, it would mean that there was a high probability that there would be that kind of huge toad infested.

After they had almost circled the underground ruins, He Qingyu saw the door, which was still hidden behind a stone wall, but this time it was not a mechanical door, but it was blocked with wooden planks and stones.

Fortunately, Gu Feng brought a mining bomb and quickly exploded the entrance of the cave, and the tunnel behind the entrance of the cave continued to go down, but there were no steps, and there was dirt all around, and the soil exuded a smell of corruption.

Everyone continued to walk down, and the light was very dim.

Black deposits began to appear around the whole thing, and it looked disgusting.

"What the hell is this place?" Lu Niang looked around curiously, the deeper she went, the more you could feel a gloomy and terrifying atmosphere, as if the surrounding darkness had seeped into everyone's skin, so cold that it was difficult to breathe.

They had been walking for more than half an hour, and Gu Fengneng probably predicted that this place was at least more than 800 meters below Canglan City.

Where does this cave lead?

Before Gu Feng had time to think about it, with the red dragon's flames, the world around him suddenly became open!

They came to a second open hall, surrounded by cube-like black hedron columns, tall, irregular, and bottomless!

The blackness of these crystals seemed to be extremely black, so black that they couldn't hold the slightest bit of light, this feeling was too familiar to Gu Feng.

"Abyss Will" and "Abyss Echo", the two materials that must be used to make alchemy items, are almost identical to this one, but the first two are only small crystals, and this ...... It's like a huge pillar that supports the entire mountain.

Everyone invariably felt the oppression of these black crystals.

"It's so uncomfortable, I can't breathe, and I'm a little dizzy." Road Idiot Sister said.

Gu Feng was also very nervous: "Either we go out first, and then slowly find a way to come in later." ”

Taishou Yilin shook his head: "Actually, it's not that uncomfortable, but I felt a little bit at first, just don't look at those pillars." ”

Lu Niang Mei and He Qingyu also nodded, Gu Feng looked at the timid girl, the little girl seemed to react, and quickly nodded, but he had a strange feeling, he always felt that the timid girl didn't react at all, she didn't seem to know what kind of oppression there was on the pillar, or that these black crystal pillars had no effect on her.

And Gu Feng too, he didn't know why, and he couldn't feel the influence of the black crystal on him, maybe it was because he had long been accustomed to the "Abyss Will" and the "Abyss Echo".

They continued to walk down these bottomless crystals, and everyone deliberately avoided looking at these dark crystals, as if the more they looked, the deeper they fell into the deep darkness.

It didn't take long for the crystal to open up all of a sudden, and the ground was full of smooth black material, something similar to glass, forming a wide hall, and the soil from the foot to the top of the head was more than ten meters high, and the black crystal was drilled out of the middle of the smooth hall, and the cracks were squeezed all around.

And around the black crystal pillar that broke out, Gu Feng saw two huge toads, but it was not correct to say that there were toads. At the beginning, Gu Feng had seen such things at the entrance of the Novice Village and the Underworld, and now he finally had the opportunity to see them in their entirety.

It looks like a toad, but a huge mouth occupies almost half of the entire body, and the proportions of the body are extremely uncoordinated. A pair of stout front paws, the hind paws are pitifully small and almost invisible.

They stood silently where the black crystals passed through the smooth hall, motionless, but Gu Feng had already suffered countless losses, and knew that this thing could not be approached, and once it got close, the defense would be ineffective, and it would be swallowed directly.

Sister Lu also gritted her teeth when she looked at this thing, you must know that she is the person who has died in the mouth of this thing the most times.

"I still can't tell the grade." Lu Niang Mei was a little decadent, Gu Feng knew why she was decadent, and she couldn't see that it meant that the monster was at least fifteen levels higher than her, and there was no time to take revenge.

And at this time, everyone looked around curiously, everyone didn't know where this was, this hall was like a mirror, an endless mirror, smooth and flat without edges, making people dizzy.

"What the hell is this place for?" Gu Feng was also curious, who would build such a large magical hall in such a deep underground, and how much manpower and material resources would be spent on it.

"Let's go up to the side and see how big it is." He Qingyu proposed, there was no edge around, but everyone agreed to He Qingyu's proposal, and then walked in one direction.

Before they had taken a few steps, a translucent figure suddenly appeared in front of them.

"Outsiders." The shadow muttered to himself.

Everyone was frightened and instantly became vigilant, but the shadows around them began to gradually increase, and translucent figures appeared one after another, constantly increasing, increasing, increasing, and increasing, and when everyone didn't react to what was going on, they were surrounded by dense translucent figures!

Everyone became nervous all of a sudden, carefully guarding the surroundings, but the shadows were still increasing, and after a while, they were completely surrounded, and they couldn't see how many shadows there were around them in the middle, only that they couldn't count what they could see in front of them.

"These shadows are fake." He Qingyu said.

Before the words fell, a shadow in front of Gu Feng suddenly stepped forward, and the short sword in his hand stabbed at once, Gu Feng subconsciously raised his shield, and with a muffled sound, his physical strength went down.

"But they can attack people!" Gu Feng hurriedly reminded loudly, and only then did he realize the seriousness of the problem, if these translucent shadows attacked at the same time.....

"Say what you came from." At this time, the voice at the beginning remembered again, coming from all directions, as if every shadow was talking, and every shadow was the one who spoke.

"I'm sorry, we're just passing by, nothing else, don't get me wrong, we'll leave right away!" Gu Feng hurriedly said loudly.

"Spineless." Taishou Yilin despised him.

"Puppy." Gu Feng blocked her back all of a sudden, and was so angry that he stomped his feet.

At this time, the dense shadows around them all stopped, and they seemed to understand Gu Feng's words.

"Hahaha, look, it's still up to me at the critical moment." Gu Feng's voice fell, and the surrounding shadows instantly moved, and they all rushed towards them!

Holding the grass, Gu Feng's heart was full of 10,000 *** galloping by, his crow mouth, he knew it earlier, so he wouldn't say it.

But at the last moment when the shadow rushed towards them, it all disappeared at once, and disappeared without a trace.

Then a slender figure appeared in front of them, her whole body was wrapped in a gray mist, very mysterious, it felt like she was there, but she would disappear at any moment, and everyone was surprised to find that although she was not wearing a mask, no one could see her face clearly.

Obviously, the many shadows just now came from her hands, and this woman is so powerful that it is terrifying! Everyone was on guard.

"You, come here." She pointed to the timid girl.

Gu Feng immediately stepped forward to protect the timid girl, and said nervously: "What do you want to do, I warn you that I am very ......"

Before he finished speaking, a translucent shadow suddenly appeared behind Gu Feng, and the unsuspecting timid girl was caught at once, and then several shadows instantly blocked Gu Feng, and the timid girl was brought to the mysterious person without any effort.

Lu Niang raised her bow all of a sudden, Taishou Yilin also began to chant, and He Qingyu said softly: "Don't worry. But she also held the grab in her hand tightly, and would rush forward whenever the situation was not right.

The mysterious man carefully looked at the little girl, and then said to himself, "I don't know what is special about you, but I am willing to trust you if they all trust you." ”

Then the shadow had let go of the timid girl, and the shadows around her had dispersed, and the mysterious man did not seem to want to hurt the timid girl.

"How did you get here?"

As soon as Gu Feng was about to speak, the mysterious person pointed to the timid girl and said, "I'm asking her, you are not qualified to talk to me, and I will not listen to your words, if you disturb our conversation, I will kill you." ”

The attitude is very arrogant!

Gu Feng was so angry in his heart, but he still didn't say anything, anyway, let her be, this woman is simply sick.

"I ...... I accidentally found a door, so I came here. The little girl said weakly.

The mystery man nodded: "You have their proof, and it's not surprising that the secret door was opened for you." ”

"What the hell is this place?" Under Gu Feng's eyes, the little girl asked softly.

"There are many names here, the Canglan Bunker, the entrance to the abyss, the third seal......"

Gu Feng tightly grasped the key word, the entrance to the abyss!

"Who are those people up there?" The timid girl asked the question she wanted to know.

"They used to be my ...... Comrade in arms. The proud mystery man hesitated for a moment, then admitted: "We fought side by side here against the abyss, and they used the castle beneath the ground as a base, and then their descendants built and inhabited the city, but they may have forgotten their ancestors for a long time." ”

Hearing this, Gu Feng was shocked in his heart, although this mysterious person said it very lightly, but he inadvertently told the origin of Canglan City, many ancient warriors tried their best to resist the abyss in this cave, while their descendants lived on the ground, and over time it became Canglan City.

In other words, you can peek into the abyss here! Gu Feng was excited.......

"And what happened to them now?" The little girl continued to ask, but she didn't ask the question of the abyss, and it was useless for Gu Feng to be anxious.

"They have been lost in the darkness of the abyss, and years of facing the abyss are not something that anyone can resist." The mysterious man showed great patience with the timid girl, and it seemed that only the timid girl was on her footing.

Under the hint of Gu Feng's crazy eyes, the timid girl finally asked the most crucial question.

"Where is the abyss, why haven't I seen it?"

The mysterious woman glanced at Gu Feng, as if she had seen through the eye contact between him and the timid girl, but she didn't say anything, but pointed to the huge irregular black crystal pillar that broke through the smooth ground in the distance and stretched out to the heights.

"That's the abyss."

When the words fell, not only Gu Feng, everyone couldn't close their mouths in surprise, that was the abyss!
