I'm trapped in a cube

"If this is the room number, does the zero residential area really exist?"

Mo Ling didn't know the specific division of the residential area of ​​the pipeline fortress. He just thought that this string of numbers might be the room number.

After checking the surrounding environment for a while, Mo Ling also fell asleep in the cube.

The pipeline room in the residential area was silent. Only Li Luo's occasional breathing could be heard. She licked her lips from time to time and frowned, as if she had dreamed of something strange.

The light became dimmer. In the depths of this pipeline fortress, the change of day and night could not be felt at all. The fluorescent light in the room flickered faintly, as if there was no difference between day and night here.

Until a dull sound came from the depths of the fortress, breaking Li Luo's dream, she slowly woke up from the sofa.

She wiped her eyes in a daze, looked at the cube, then looked at her backpack, and stood up.

Standing in the center of the room, Li Luo looked in the direction of the muffled sound. It seemed to be the sound of some huge steel friction, or something falling into a furnace and being hit hard.

The sound was deep and had become a little unclear when it reached here, but it was unusually harsh in this quiet pipe room.

Li Luo picked up a bottle of water and drank it down.

She had just had the dream about Dr. Liu again, but this time the dream became very vague and not as real as the first time.

Li Luo picked up the electronic screen and looked at it.

"Three o'clock in the middle of the night... I didn't sleep for long this time."

This time she didn't sleep for three days like before, but just slept normally, but the vague dream also made her have a headache after waking up.

"Then how long will the cost of the pain-reducing pill last?"

Li Luo realized that she might have underestimated the cost of the pain-reducing pill.

Just as she was worried, the cube flew over, and then an electronic screen appeared out of thin air on the table next to her. Li Luo immediately understood that the cube was going to tell her something.

Li Luo picked up the electronic screen and saw the speculation about the string of numbers on it.

"Room number? Residential Area Zero?"

At the same time, there was another question on it:

"Why do you care so much about the source of this relic?"

Li Luo then realized that she had never told anyone about the dream.

Since returning to the Pipeline Fortress, she has been looking for the source of the pain-reducing tablets, and also to figure out the impact of this relic on herself.

Fang Kuai didn't know about the dream, so of course he didn't understand why she cared so much about the pain-reducing tablets.

Thinking of this, Li Luo looked at Fang Kuai on the side and said seriously: "The price of this relic may not be as simple as written in the information..."

Li Luo told Fang Kuai what he dreamed about, and also expressed his recent feelings.

After being treated by doctors in the Huasheng Islands, Li Luo did get better, but the cost of the pain-reducing tablets seemed to be persistent.

She would feel thirsty from time to time, and sleepiness would come up inadvertently, and the things about "Doctor Liu" would keep reappearing in her dreams, and sometimes when she was daydreaming, she would unconsciously think of these things.

It seemed that the dream was completely left in her mind, constantly bothering her.

Li Luo knew clearly that there was something wrong with her body, and in order to solve these problems, she had to figure out the secret of the pain-reducing tablets.

"The dream seemed to urge me to find what was hidden behind this relic..."

"I don't know if my thoughts were controlled, but what happened in the dream did fill my mind and made me think about it all the time."

Li Luo licked her lips while speaking.

She had just drunk half a bottle of water, but her lips were still terribly dry at this time, and faint cracks appeared on her somewhat pale lips, and a strange bright red appeared in the cracks.

Li Luo swallowed her saliva, and her tongue moved, rolling up the dry dandruff on her lips. The cost of the pain-reducing pills was still affecting her.

The electronic screen was taken back. Mo Ling looked at Li Luo's strangeness and wrote a short sentence on the electronic screen:

"I will help you."

...

Fortunately, although the side effects of the pain-reducing pills continued, they were not terrible.

Li Luo only adjusted for a while, then picked up the electronic screen and began to look up the "zero residential area".

Sure enough, in the database of the pipeline fortress intranet, she found records about this residential area.

When the pipeline fortress was first built, there was no division of residential areas.

At that time, not many people could come to the fourth floor of the abyss, and even fewer could come to the pipeline fortress. Moreover, at that time, humans' control of the pipeline fortress was not so sophisticated, and it was impossible to create pipeline rooms like now.

Therefore, people could only simply divide an area into residential areas and separate the pipelines inside for living.

At that time, the main purpose of people was to explore the pipeline fortress, so the management of the residential area was very chaotic. People used the relics and tools at hand to transform the residential area, making it more like a camping site where people gathered and it was messy and disorganized.

Such a living environment is of course very poor, so after people were able to finely control the pipeline fortress, they created a new residential area and eliminated this old residential area. The people here also moved out one after another, leaving only a ruin.

However, the previous transformation of this area remained, and the people in the pipeline fortress called this area the zero residential area.

As time goes by, many people have forgotten the existence of this residential area.

There are many such abandoned areas in the pipeline fortress that no one cares about. In addition to the records in the database, the newcomers coming and going in the fortress don’t know these places at all.

Looking at the records on the electronic screen, Li Luo realized that the string of numbers might really be related to the zero residential area.

So, she hurriedly began to look for the location of this residential area.

Soon she found it. This residential area is located directly below the first residential area, which is a relatively deep place in the pipeline fortress.

"The first residential area?"

Li Luo opened the map. The first residential area is not far from here, but the road may be a bit roundabout.

Seeing this, she could no longer suppress her inner impulse and directly picked up the backpack on the ground.

"Let's go now."

...

Walking in the empty pipe, the sound coming from the depths became more and more obvious.

It seemed that some huge metal machinery was turning, and there were some rhythmic knocking sounds in the turning sound. I don't know whether the metal machinery was knocking on other things, or other things were knocking on the machinery.

Following the map, Li Luo quickly found the location of the first residential area, but the first residential area was not their goal. She bypassed the pipe at the entrance and came to a tattered pipe next to it.

"Is it here?"

It seemed that no one had walked through the pipe for a long time. The small pipes laid at the bottom were a little damaged and covered with dust. The lighting in the pipe was also flickering and looked dilapidated.

Li Luo confirmed it and walked into the not very spacious pipe.

The pipe was about four meters in diameter and spiraled downwards with a steep slope. If one was not careful, one might slide down. Li Luo could only lean against the edge and step carefully on those broken pipes.

After going around for an unknown number of times, the pipe finally became flat, and some dilapidated facilities appeared in front of him.
