"Why don't you install a lifting system like the one on top? Descending in a spiral down the staircase in the last shaft, Catherine asked, "I can't say that the goblins have to walk for so long when they come down on their own." ”

Distance and enthusiastic indulgence were separated, and an hour had passed, and for a full hour, the four of them had walked almost all the way down the shaft. In the dark and monotonous space, everyone felt that they had gone a long, long way down, but in reality they had only descended a few hundred meters. Of course, this is not actually an illusion, because of the spiral staircase, although the straight line is only a few hundred meters long, but in terms of distance, it has indeed walked a few kilometers, due to the psychological tension and the muscles can not relax, the two maids are already a little panting, sweat beads continue to come out of their faces.

"I suspect that this is just an emergency entrance, so there are only stairs, and the really commonly used maintenance entrances and exits should be equipped with lifters, otherwise with the physical fitness of ordinary goblins, it is easy to come down, but it is difficult to climb up. Vivien explained a few words to Catherine, then suddenly turned to the two maids following behind her and said, "You two had better change your clothes now, and you will have to change them at the end anyway." ”

"Change your clothes?" asked Pansy and Mimosa, puzzled, "Why do you want to change your clothes?"

"Don't you feel hot? Don't forget that you are different from me, our physical fitness allows us to wear ordinary single clothes even in winter without feeling cold, but you are ordinary people, and you must be wearing thick clothes now. Vivien explained, "The further you go underground, the hotter it gets, so you're sweating now." Take off a few pieces of thick clothing, or you'll be dehydrated just because you're sweating after spending a long time underneath. ”

"Well, it looks like it's coming. When the maids had changed their clothes, Catherine once again leaned on the metal railing and looked down for a while, and said with some joy, "This should be the last section." I don't know what the goblin sewer system looks like, I've never seen it. ”

"It's nothing more than a sewer, dark, cramped, damp, dirty, sticky, bug-infested, smelly. I used to go to the sewers of the Holy Capital once when I was doing research in the Holy Capital, so I guess it should be no different. Vivien wasn't as expectant as Catherine. With a bitter face, he said: "Anyway, if it's not a last resort, I definitely don't want to go again." ”

"But...... However, the Shadow Hand has built a base in the sewers, and if it's really like what you say, how can they stand it? Catherine retorted, "And indulge them too." Except for a few areas below, most of the venues don't need lights, so it's not as exaggerated as you say. ”

"If you don't believe me, see for yourself later. Vivien snorted lightly and jumped down the final steps in a few steps: "This should be the last transit station, look ahead, follow the down stairs, it should be the main line of the sewer, on the map given by indulgence, this main pipe is marked with the thickest line." ”

"Shhhh Pansy, you turn off the lights. Catherine suddenly frowned and waved her hand at the maid sisters, and said in a low voice, "You see, there seems to be light coming up from under the stairs. ”

"Hey, it seems that there is really light. Vivian's heart also tightened, and she asked in a low voice, "Someone?"

"No, there were no voices, it seemed like just lights. Catherine shook her head and said, "You wait here, I'll take a look first." ”

"Don't be impulsive. Vivien grabbed Catherine's wrist as she was about to move forward, and the eyes of the two girls met in the air for a few seconds, and Catherine nodded slightly. Vivien let go of Catherine's wrist: "Be careful. ”

The three who stayed behind watched Catherine silently descend the stairs after wrapping the soft leather around her feet, carefully probing around the corner. Catherine poked her head out, and her body stiffened. It wasn't until dozens of seconds later that he waved his hand to the three people behind him: "Come down, there's nothing, it's safe." ”

The three of them also slowly walked to Catherine's side, and looked at her like her. Like Catherine, she was shocked by what she saw.

The image of the underground waterways in front of her was far beyond Vivien's expectations, even beyond everyone's expectations, no darkness, no crampedness, no oppression, no peculiar smell, this is not like a sewer system, but like a city in the center of the earth. The main pipe of the sewer is made of giant tubular stone columns with an inner diameter of 30 meters, and the branch pipes are spliced with two inner diameters of 25 meters and 20 meters. At the bottom of the pipe, there is a canal seven meters deep and eight meters wide, with an arc at the bottom, and 10,000 years ago, the city's wastewater was collected here from countless branch pipes, and then transported far away from this canal to the sea. There is a two-meter-wide walking path on each side of the canal for maintenance crews to pass through.

At the top of the sewers, the goblins inlaid countless fluorites that can emit their own light into the stone in the middle, forming a band of light that spreads throughout the sewer system, so that most of the sewers can be in light at any time. Not only is this setting convenient for maintenance work in the sewers, but the presence of light, even if it is fluorescent, can also prevent the breeding of demonic energy to a certain extent, and prevent the phenomenon of monsters from running wild.

"Here...... Is it really a sewer?" Catherine muttered, "If the water canal above ground is filled, this space will be enough for a small group of knights to charge side by side." ”

"Phew, the skills and strength of the goblins have once again refreshed my cognition. Vivien let out a sigh and looked up at the fluorescent ribbon above her head in distraction, "I finally understand what that elven mage's prophecy is. ”

Dark, wide, dry, wet, filthy, clean, dangerous, this is the prophecy of the elven mage, and neither Vivien nor Catherine could understand this contradictory prophecy, and even when the indulgence explained that it meant that it was a sewer, it was difficult for them to imagine it, until they saw the real thing, and they knew that there was nothing wrong with the prophecy.

There is no difference between dark, damp, and filthy things that describe things like sewers, and broad, dry, and clean things that depict things in front of you. That's right, the sewers are now dry and clean. Perhaps 10,000 years ago, when the sewers were still in use, they were indeed damp and filthy all year round, so much so that they were smelted by goblins. It is also necessary to pour a layer of hard gelatinous body on the inner wall of the metal pipe to isolate the metal body from the outside world to achieve the purpose of rust prevention. However, more than 10,000 years have passed, and the system has long been free of sewage flow. All the inside of the tube body has become very dry. Moreover, due to the passage of time, the sludge brought by the sewage inside the pipe has long been weathered and solidified, turning into a hard stone structure, so that the inside of the pipe is no longer dirty, and even becomes very clean due to the existence of cleaning puppets.

Look along the main pipeline. Every few hundred meters, there is a secondary pipe with an inner diameter of 25 meters that extends diagonally upward, and the secondary pipe is divided into branch pipes with an inner diameter of 20 meters at intervals, and the branch pipes are divided again, which is the pipe leading to each drainage channel and sewer. Like the roots of a tree, this vast drainage system continues to extend into smaller branches, linking medium-sized urban agglomerations of more than 1,000 square kilometers.

Of course, this was 10,000 years ago. Today, 10,000 years later, the main pipeline is still well preserved, and most of the secondary pipelines and branch pipelines are still normal. But the lower branches, that is, the pipes that connected to the ground level of the original goblin city, have basically been blocked by the thick layer of earth and stone hundreds of meters above the head, and it is completely impossible to continue climbing upward. As a result, the area was completely cut off for 10,000 years.

"Vivien, you say, is it possible that we wandered around the underground waterways and stumbled upon the ruins of a goblin city buried deep underground. Catherine's eyes sparkled, and she said excitedly: "Then I found a lot of treasures left by the goblin empire from the city, hahahaha." Then you will get rich. ”

"Eldest sister, it's not night yet, it's too early to dream. Vivien rolled her eyes weakly, "Help me and put me at the bottom of the canal." I'm going to carve something. ”

"Well, don't you think it's possible?" Catherine sighed, dispelling her illusions, and dropped Vivien into the ditch with a drop rope.

"Actually, theoretically it is not impossible, there may be such a city. Vivien's voice came from the bottom of the canal: "But the probability is that you accidentally fell while walking on the road." As a result, a high-content vein of magic steel was found by the way, and En'en may be even more likely. ”

"Forget it. The hope in Catherine's eyes slowly extinguished, but she was not at all depressed: "But no matter how unlikely it is, maybe it can be realized." By the way, what are you carving?"

"Marker, alright, pull me up. Vivien put the safety rope on her body, was pulled back onto the walking path, patted her clothes and said, "Within 200 kilometers, I can sense the location of this marker." If we accidentally get lost and can't find this exit, with this thing here, at least we won't go further and farther. It's a pity that if the teleportation circle is not engraved on a special base, it will only be valid for forty-four hours, otherwise if you carve one here, and carry the other half of the portable one with you, you will never get lost. ”

"Above. Catherine's ears suddenly moved, and she pulled Vivien back quickly, retreated to the maid sisters, raised her shield to protect the three of them, and then looked up. At the top of the pipe, several spider-like metal golems, completely ignoring the four people below, were crawling at the top, occasionally stopping at a certain point along the way, and when they left, the slight damage to the hard gum had been repaired.

"It looks like it's a puppet for repairs. Vivien stared eagerly at the top of her head, "Indulge them without telling us." ”

"I guess they don't know. Catherine said, "They probably haven't explored outside, and all the golems in and out of their base were sealed off decades ago, so it's normal for them not to see." This doesn't seem to affect us, so let's go.
