The Ninth Secret Bureau

It's warm in the tank, and it's also very...warm.

This is Chen Xian's first feeling.

The former can be explained by tactile somatosensory, but what about the latter?

Chen Xian couldn’t understand why he felt at ease when he fell into this water tank. Those weird black liquids weren’t a good thing to look at, but he didn’t feel resisted when he was immersed in it. No desire to climb out...

Soaking in this tank of dirty liquid, Chen Xian's concept of time became blurred, and he could not perceive the passage of time at all, as if even his consciousness became blurred.

After an unknown period of time, Chen Xian gradually woke up and opened his eyes with "enjoyment" on his face.

At this time, the black liquid in the tank was nearly exhausted, leaving only part of the more viscous residue.

Chen Xian remained lying on the bottom of the tank while the girl squatted silently in the corner, looking at him with a very happy look.

"Where are those black water?"

When Chen Xian asked this, he had already sat up, raised his hand and gently rubbed his shoulders a few times, feeling uncomfortable all over his body, as if all the tiredness and sleepiness had disappeared.

That kind of satisfaction and comfort from the heart is hard to describe in words.

If you want to compare it, it feels like someone who has long-term insomnia suddenly took a good night’s sleep and is still in deep sleep...The strange satisfaction and comfort when waking up, it’s the same as Chen Xian. It feels similar at times.

After waking up, Chen Xian seemed to hear the pleasant sound of his soul, as if every cell in his body was cheering and singing.

This refreshing body feedback made him very curious, what exactly are those black liquids?

At this time, the girl yelled twice, and stretched out her hand to pat the rubber tubes on both sides.

From previous observations, the black liquid seemed to have flowed out of these rubber tubes, but at this time, no matter how the girl slapped, the rubber tubes didn't respond.

The girl looked back at Chen Xian in disappointment, screaming, like a child who wants to eat sweets but can't eat it, she seems to be wronged and cry at any time.

"Go out first."

When Chen Xian finished speaking, he got up and walked out of the water tank. The girl also hurriedly jumped out, following Chen Xian like a small tail.

Standing by the water tank, Chen Xian carefully observed it for a while, and the doubts in his heart grew thicker.

There are many strange things about this appliance, and there is currently no way to determine what it is made of.

The cylinder wall is very thin, but about 5 mm. Through pressing and knocking tests, you can feel the glass-like hardness, without any toughness at all, and judging from the feedback of the knocking sound, it is crisp and sound, and it is indeed a bit like knocking. The sound of hitting the glass.

What made Chen Xian most curious was this layer of blackness.

Such a special black with very low reflectivity and unusual, reminded him of the special product Vantablack of a British scientific research company that he had seen in the literature. The Chinese name is also called carbon nanotube black body.

This special substance is the darkest known substance on the earth. It can theoretically absorb nearly 100% of electromagnetic radiation in the visible light band. In other words, it can absorb most of the visible light, and the reflectance is almost negligible.

"If I remember correctly... the carbon nanotube black bodies are all used as paint..." Chen Xian stroked the edge of the water tank and murmured: "Is this water tank coated with a layer? This substance?"

After studying the cylinder body for a while, Chen Xian was unable to draw a definite conclusion. In desperation, he could only turn his attention to the six black rubber tubes.

Those pleasant liquids flowed out of these tubes. The tubes looked nothing special and felt very ordinary, much like the common hoses used to transport liquids in hospitals.

At this time, Chen Xian suddenly recalled the mechanical roar he had heard before, and then subconsciously looked down.

Is there some kind of machinery under this water tank?

Judging from the arrangement of the rubber tubes, it does lead to the bottom of the water tank...what's underneath?

The previous liquids left a very deep impression on Chen Xian.

When immersed in those liquids, he got the kind of feedback that seemed to have returned to his mother's embrace, which made Chen Xian unable to control the curiosity in his heart, and developed an uncontrollable and extremely strong curiosity about their origins.

Chen Xian pulled the water tank and tentatively dragged it, and quickly came to some conclusions that the density of the water tank should be very high, and the total weight should be 400 kg to 500 kg. Then contact the previous one. Knocking feedback... This water tank may be really made of glass.

When Chen Xian completely removed the behemoth, the six rubber tubes connected to the inside of the cylinder were also disconnected and fell to the ground one after another.

Facts have proved that Chen Xian's move to remove the water tank is completely correct. If he does not remove the water tank, he will not be able to find the things hidden at the bottom of the water tank.

There is a piece of golden metal that seems to have been melted by high temperature, and two forms that are incomplete and stained with blood, but the most important thing is...Chen Xian found a strange entrance.

It is a metal door that is turned upside down.

There is no lock on the door, and there are six small holes on the edge, and the rubber tubes are drawn from here.

With a curiosity, Chen Xian was not eager to study the door, but first picked up the scattered things on the ground.

Let me talk about that piece of metal first.

From the touch and texture point of view, it is no different from ordinary copper metal. Chen Xian suspects that this is just some kind of part or scrap. It seems that it has lost its original shape after high temperature smelting, so he can only guess, but can't conclude. What is this.

Look at the other two forms.

One of the forms was completely stained with blood stains, and the fonts were too fuzzy to be recognized, and there was no research value at all. The other form was slightly better, except that a large area was stained with blood stains, and a few lines of words were spared.

"March 1, 08:11—Maintenance Department: Zheng Gang."

"The maintenance work of the nutrition tank was completed. No damage was found in the tank body. The continuous leakage has been reported to the superior in time and put on record. The logistics staff started to replenish the tank body with nutrient solution for the third time. The current replenishment progress is 63%, and it is expected to be replenished around 14:00 complete."

"March 2, 04:01—Maintenance Department: Zheng Gang."

"Comprehensive overhaul of the nutrition tank was completed. Once again, it was confirmed that the tank body was not damaged, but the cause of the leakage was still not found. The fourth time the tank body was supplemented with nutrient solution, the current replenishment progress is 12%."

"March 3, 05:24—Maintenance Department: Zheng Gang."

"The nutrient tank has leaked again, and the cause of the leak was still not found during the second comprehensive overhaul. It has already reported to the superior to apply for a replacement of the nutrient tank, and started the fifth time to replenish the tank with nutrient solution. The current replenishment progress is 1%."

On the blood-stained form, the only recognizable content is these few lines, which looks like some kind of punch card or temporary record.

Nutrition cabin?

Chen Xian put down the form in his hand and turned to look at the black water tank aside.

"Is this the nutrition chamber mentioned in it?" Chen Xian looked at the water tank half-trustfully, and then at the slightly scribbled font on the form, feeling a bit embarrassed, "If it's really this...the black liquid Isn’t it just a nutrient solution..."

Chen Xian has never come into contact with such a device as a nutrition cabin. He has only seen some prototypes similar to the nutrition cabin in science fiction movies, but no matter what the shape is, its function will inevitably remain the same.

According to the concept of the nutrition cabin in the movie, it is a special container for storing the human body. Even if the living people in the nutrition cabin do not eat or drink, the nutrient solution it provides can fully satisfy the energy needed by the human body, just like a movie. Most of the nutrition cabins here are used to heal injuries... Does this big water tank also play this role?

Chen Xian looked through the form in a puzzled manner, and felt that the water in this mental hospital was getting deeper and deeper. Why did he feel like he was bottomless?

While Chen Xian was thinking about this, the girl suddenly stretched out her hand to take away the form in his hand, tilted her head and looked at it very seriously. She didn't seem to understand much, and she crumpled and threw it aside.

"Hey, don't throw it around!" Chen Xian hurriedly bent over to pick it up.

The moment he picked up the form, the girl took the opportunity to take away the copper-colored metal in his hand and the identity card that belonged to her. A set of actions caught Chen Xian by surprise.

What's the origin of this girl?

Why is the craftsmanship of grabbing so skillful?

"Give it to me." Chen Xian opened his palm to the girl solemnly and looked at her seriously, "It's better to put these things here, I'm afraid you will lose them accidentally."

The girl didn't know whether she had understood Chen Xian's words, tilted her head and looked at him for a while, her eyes staring blankly.

"Come on, give it to me."

Chen Xian kept his tone down as much as possible, so as not to stimulate the girl with unknown mental state. But it turns out that no matter how gentle his voice is, it's useless. The girl just smiled stupidly and didn't give him anything back.

At the same time, there was a sudden moan of pain in the corner of the room.

"I just... was knocked out by something..."

That's right, Fatty Huo woke up at this juncture.

I saw the fat man holding his head and groaning, his face was filled with the word pain, as if he was relatively confused when he was just awake, his speech was intermittent, and his eyes could not be opened.

"Xiao...Xiao Chen, are you still there..."

That kind of groaning and groaning sound is both grievous and prolonged, so it's okay to dub a horror movie.

"I'm not going to die anymore..." Fatty Huo became a little more sober, slowly opened his eyes, and his tone suddenly became tense, "It's so dark here... "

black?

Black is right.

Chen Xian muttered to himself, his expression more nervous than Fatty Huo.

When he heard Fatty Huo groaning, Chen Xian directly turned off the only flashlight and dragged the girl to hide beside the big water tank. The two squatted on the ground like thieves and did not dare to let the fat man find out.

"Well?"

The girl looked at Chen Xian strangely, as if she didn't understand why he wanted to do this.

"It's going to be troublesome..." Chen Xian surreptitiously observed the situation on Huo Fatty's side. Regardless of whether the girl could understand her own words or not, he cautiously told her, "Don't go out. Sounds."

It turns out that the girl didn't understand Chen Xian's words at all, instead she squatted on the ground and fumbled for a while, for fear that Fatty Huo wouldn't notice here.

She fumbled on the ground for a while, and soon found the metal door that had been blocked by the water tank.

Without waiting for Chen Xian to stop, the girl grabbed the concave doorknob and slammed the metal door open.

"Hey shit! What is it?!"

Fatty Huo was immediately screamed out of fright. It was originally dark here, and he couldn't see the situation with his fingers. Besides, he didn't know where Chen Xian was, and he almost suffered a nervous breakdown.

In fact, it's not that he is timid, who has gone through all the weirdness of this mental hospital and was suddenly thrown into the dark by himself. Who can't be afraid?

"You keep your voice down!"

Chen Xian suppressed his voice and didn't dare to shout out, but he turned his head in a hurry and found out...

The girl is gone.
