Standing under the city gate, looking up, you will realize the enormity of the city.

The tall walls were in no way inferior to any city on land, and the fortress was probably made of local materials, made of the white bone and gravel of the place, and the entire fortress was almost completely enclosed, except for a few lookouts on the top, and guards could be seen patrolling it.

Seeing Lawson and the others approaching, the guards immediately informed the city gate, and the three of them didn't have to wait long before the heavy bone gate opened one of the side doors, allowing them to enter the fortress.

Walking into the fortress, Arandall saw a scene that was diametrically opposed to the impression from the outside.

The oncoming wind smells of moist soil, and then the green dominates Irandall's vision.

It's a tree.

These trees have thick trunks and no extra branches, and countless leaves cover the trunk and look like a green column.

Both sides of the road are lined with such trees, lush, and in front of the road is a bridge, under which the water is murmuring, and the birds are singing, like a quiet forest.

In the sky, two pairs of winged birds are soaring, and Irandall sees that the sky here is actually the dome of the fortress, which refracts and directs light from the outside into the fortress to provide light for the plants.

Around the dome, there are many small caves, which are connected by stairs and look similar to the style of the Nether Cave.

As soon as Rosen and the others entered the fortress, they met the host.

It was an emaciated young man with heavy dark circles under his eyes and a listless look.

"Are you new explorers? I'm Hughes. ”

He introduced himself, his voice flat and undulating, sounding more like a puppet's recitation.

"We want to go to the next level, and we want to get permission from the owner of the fortress. ”

Fina scrambled to speak.

Rosen didn't say much, to be able to build such a huge fortress in the endless abyss, presumably its owner also has a certain ability, since there is a normal way, then they just act according to the rules.

"Yes, then please follow me. ”

Hughes didn't ask, but turned around and started moving forward.

The three of them followed the young man and walked through the fortress.

Edlandall found that although the fortress was called the Abyss City, it didn't actually have too many inhabitants, many of the rooms on the walls were vacant, there weren't many people walking on the streets, and the occasional child passed by, but it didn't seem to be very energetic.

"The passage to the next level is in this fortress, on the one hand, to resist the attacks that sometimes come from the lower levels, and on the other hand, to avoid unnecessary casualties during the expedition, so the path to the fifth level of the Endless Abyss is controlled by the master here. ”

"The owner of the fortress......"

Rosen thought to himself, his perception spreading through the fortress, secretly probing the surrounding situation.

He found that Hughes, who led the way, did not have the strength of the upper reaches, in such a deep endless abyss, this strength was not enough at all, and most of the pedestrians around him were wandering between the black iron and the black iron, and they couldn't even see a single bronze.

If the average strength of the city is concerned, then Rosen is very skeptical about how the city has survived in this barren desert for so many years.

As they walked along the road, they found that most of the road was built around a patio in the middle of the city, and when they looked up at the patio, they could faintly see the light from the inverted ocean, which presumably refracted the light into the fortress.

Below the patio, there is a simple circular building, which looks down on the inside from the outside, and the light falls on the building, giving it a somewhat hazy brilliance.

Rosen thought that it should be the road to the next level, and in the round building, it should be a hollow.

The direction in which they were then going confirmed Rosen's suspicions, and after a bit of tossing and turning, they came to the gate of the circular tower in the middle of the city.

The tower was about six stories long, and the white walls were unmiscellaneous, and it must have been built by a skilled craftsman, Irandal thought, and then saw the door open.

A man walked out of the door.

"Is this the owner of the fortress......"

Rosen looked at the man, but he was not surprised.

And Fina and Irandall are not so calm.

It's really because the person in front of me is too weird.

He hid his entire face in his hood, tall but draped in a thick trench coat that didn't seem to want any inch of his skin to be exposed to the air, and the man wore heavy gloves and spread his hands as if to welcome the three of them.

"Hello, I'm the head of this fortress, you can call me Isaac. ”

His voice was low and had a strange texture.

"Isaac !?"

Naturally, Irandall and Rosen didn't know, but Fina's eyes widened when she heard the name.

"Could it be the Abyss Returner, Isaac the Hand of Light, who was active fifty years ago and successfully returned from the fifth level of the Endless Abyss?"

"Oh, I didn't expect such a young girl to remember my name, what a surprise. ”

Isaac's tone was calm, and he couldn't hear any emotion.

"I heard you're going down to the fifth floor?"

Without any more pleasantries, Isaac changed his words and cut straight to the point.

"Yes. ”

Rosen replied, from this Isaac's body, he felt a similar aura to his own for the first time, the other party was very strong, and it was even possible that he had broken through the bronze to the silver, and there were a few wisps of inexplicable feelings, if he could, he did not want to be hostile to him.

"The fifth layer has been a little unquiet recently, especially in the past two days, I can feel that the Endless Abyss is restless, I don't recommend that you choose to descend now. ”

Isaac said lightly.

"Besides, this little girl's physique is too poor, although I don't know how you descended to this level, but for now, she can no longer return to the ground, and if the exploration on the fifth layer is hindered, she will no longer be able to return to the observation post on this level, the rising load will directly kill her, as the garrison of the fortress, I can't allow this kind of meaningless sacrifice to appear. ”

"Atlantia on the ground has been flooded by the Demon Tide, and we can only solve this crisis by going to the deepest depths of the Endless Abyss, I know what I'm doing, Lord Isaac, please let us pass. ”

Fina said, very resolute and unwavering.

"Is that so...... Wait a minute, if you may, can you tell me your name?"

Isaac nodded, then asked as if he had suddenly remembered something.

"Fina, Fina, Noelle. ”

The moment Fina said her name, Rosen could feel the aura on Isaac's body change abruptly.

A strong killing intent emerged.

"Be careful!"

He directly pulled Fina behind him, and the next moment, the original location of Fina was directly destroyed by an unknown force, leaving only a huge hole, in which the sand and gravel melted and turned into glass-like crystals.

"I'm sorry, it's just you, I can't let you through. ”

Isaac
