Catherine and Vivian walked into the building in front of them with two nervous maids. The building only has one floor, and from the outside, it covers a large area, and it looks like there are many rooms. But when you actually walk in, you find that there are only a hall supported by columns. In the middle of the hall is a giant vertical shaft with a diameter of thirty meters and a brick and stone wall. The shaft is 30 meters deep. The wellhead is fixed with a crystal energy lifter with metal support poles and cables. Vivian tried it and it seems that although the Shadow Hand abandoned the former headquarters, it did not completely give up on this entrance. The lifter is often maintained and can be used. He arrived at the bottom of the shaft and found a door built on the bottom side. He opened the door with the key left by enthusiasm. The top construction technology of the Goblin Empire was finally presented to the girls.

Appearing inside the door is a large space made of metal, and in the middle is another downward shaft. But unlike the vertical shaft above which is obviously belonging to the recent construction technology of the Quaternary period, this time the inner wall of the shaft is composed of silver-white goblin metal, just like other goblins, and it has not caused damage to these metals even in ten thousand years. Closely against the inner wall is a four-meter-wide metal step, which spirals down along the inner wall, extending downward, and the end of the field of view. Looking down against the guardrail of the step, there is a dark pit that cannot be seen at first sight. The darkness in the pit gives people a illusion of continuous rolling, like facing the endless abyss of hell.

"Are you ready?" Katherine held her hand on the door of the metal space and said solemnly to the two maids: "Are you nervous?"

"A little." Even though Pansy and Mimosa grew up in the dark alley area, they have never faced such a strange world. The perseverance that was trained in the struggle of the same kind was defeated in the face of the unknown fear. The two maids were not stupid enough to try to forcibly hide their fear. They said with a trembling trembling: "It's really a little nervous to face these for the first time."

"You must come with me nervous?" Vivian lowered her head and stuffed a large number of crystal bottles into the pockets hidden everywhere in the blue work clothes she had replaced. She said without raising her head: "It's still time to look back now."

"Thank you for your concern, two ladies." Pansy pressed her hands on her thighs and bowed: "But we must follow."

"Have they threatened you with enthusiasm and indulgence?" Catherine asked a question that they didn't say in front of them.

"No, there is no threat. It is a temptation, a temptation that cannot be refused." Pansy said with a wry smile: "This morning, the two adults promised that as long as we can help the two ladies get out of here safely, we will introduce a job outside that can support ourselves and will not dare to hire us because we are from the City of Innocence. This is something that every ordinary civilian in the City of Innocence cannot refuse."

"So you don't want to stay here all the time," Katherine sighed.

"Yes. If there is no other way to live, who would be normal people willing to live here?" My sister Mimosa is a little outgoing than her sister, and she is a little more courageous than her sister. She complained again: "Sometimes I even think that even if I starve to death and freeze to death outside, it is better than being killed quietly in the City of Innocence. Unfortunately, I just thought about it. I didn't have the courage to really go out and starve to death. But now I finally saw an opportunity, which may be very dangerous. But the benefits that can be obtained without danger must be traps. The more dangerous the benefits, the more real the benefits. How can we not seize such opportunities?"

"They've probably thought they wouldn't refuse to talk to you." Catherine looked at the backpacks behind the two maids and said, "So have you prepared a piece of supplies?"

"Yes. Thirty days of food and drinking water, sleeping bags and some daily necessities." Pansy replied: "Our physical strength can only support us in memorizing this."

"It's enough." Catherine nodded and said, "Since you have made your own choice, then follow us. If you encounter danger, don't run around. Try to squat beside me. This is the safest way to deal with it. In the end, if there is danger, I will definitely find a way to save you. However, anything in the adventure may happen. If I can't save..."

"That's the luck that we didn't bear the stable life outside." The sisters were not uneasy about Catherine's statement, as if they thought it was natural: "You are willing to help us as much as possible. We are already grateful."

"Everything is ready?" Catherine looked at Vivian at last.

With a "bang", the staff in Vivian's hand paused gently on the ground. A high-consumption crystal energy lamp visited on the ground suddenly illuminated, and the light illuminated the entire interior of the cylindrical building. Vivian frowned, looked at Catherine, tilted her head and thought about it, turned off the high-consumption crystal energy lamp, took out a normal crystal energy lamp she carried and took it in her hand to light it. The light of the ordinary crystal energy lamp was obviously weaker than that of the high-consumption varieties, and could only illuminate the range about ten meters around everyone. However, with the visual ability of a professional, although the light was dim beyond ten meters, it could still be seen clearly, and it was just a little blurry.

"Haha, Vivian, you're awesome." Catherine felt a sense of joy from the bottom of her heart: "Your behavior made me so excited that I wanted to cry."

"Anyway, they have given us these supplies. If you can save a little crystal, you can make more money. That's what you think." Vivian gave Catherine a blank look and ignored Catherine who was intoxicated by saving a lot of lighting crystals. She handed the lamp in her hand to Pansy and handed the same lamp to Mimosa, but it was just turned off: "You hold these two lamps, one for each person, Pansy, you are responsible for lighting the whole process. If one of you is separated, don't run around and lean against the wall to keep the lamp in the lighting state, we will naturally find you along the light. Okay, sister, everything is ready."

"Huh." Catherine packed up her mood and took a deep breath. She slowly but firmly closed the door of the metal space. The light from the outside was completely blocked by the door, and the crystal energy lantern inside the door became the only light source in the world: "Okay, the adventure begins, come on."

"Ding, ding. Ding." The tiny metal collision sounded in the dark sewer. The quiet environment amplified this subtle sound countless times and became extremely clear. The four of them took advantage of the light of the crystal energy lantern and went down step by step along the metal staircase, disappearing little by little on the ground. Look up and down. The upward staircase seems to be unable to see the end, and the downward staircase also seems to be unable to see the end. At this moment, the world seems to be shrinking infinitely, shrinking into the downward path in front of them, and the four people climbing in it are the only life in the world, moving forward endlessly in the dark space.

There was no sound of wind or dripping water. In the quiet world, only the slight footsteps of the three people and the sounds made when Catherine's metal shin guard collided with the metal ladder. The circular space constantly reflected the sound, creating frequent echoes above the four people, as if there were many people who could not see followed behind the four people, closely following them to the abyss.

"I. I'm a little scared." Mimosa said in a trembling voice, but the slight sound became as loud as thunder in the quiet and empty environment, making her legs almost collapsed.

"In such an environment, anyone will feel a little timid. No matter how strong the will, it is nonsense to say it is not nervous." Catherine sighed and comforted: "For adventurers who often go in and out of various ruins, there are many ways to relieve tension. The most commonly used one is to speak. Speaking can not only dispel tension in the heart, but also let your companions understand their dynamics and location at all times. Of course, the disadvantage is that the enemy can also understand your dynamics and location at all times. So it is disabled when there are enemies around."

"But I think you're very calm." Mimosa tried to relieve her nervousness by speaking: "Have you ever experienced this kind of environment before?"

"I've experienced it, that time is much worse than it is now," Catherine recalled with a smile: "Now, at least you two are holding lights. It is visually guaranteed. The environment we were in that time could encounter crisis at any time, and everyone had to prepare for battle, so there was no possibility of carrying the lantern forward. We could only observe the surroundings with very weak light. It can be said that even vision was deprived."

"It's scary to think about it." Pansy joined the conversation: "You adventurers often have to face this situation?"

"Well, it's not true," Katherine replied. "There are many kinds of jobs for adventurers, and those that need to go deep into the ground are usually searches or explorations, because ancient ruins have often been buried deep underground. As for other tasks, we rarely drill into the ground before. However, we experienced an underground adventure a few months ago, so we have sufficient experience. After all, compared to natural underground caves and harsh environments, this kind of artificial building is simply a paradise."

"It should be at the bottom." Vivian, who had been silent, did not fall into the usual contemplation. He suddenly looked up and said, "Although there may not be monsters and cleaning puppets in this longitudinal shaft, it is better to be warned."

"So fast?" Catherine looked down the metal guardrail. Sure enough, less than twenty meters below was a flat metal floor: "Didn't it mean 840 meters? Including the three hundred meters of shaft at the beginning, it was just over 400 meters, right?"
