That night, it should be said that in the tenth hour of this long night, everyone fell asleep, except for Liu Peijia, who sat on the floor to keep vigil.

The laboratory was silent, as long as Liu Peijia didn't sleep, there was no only source of noise, and for a moment he felt like an Eskimo, squatting in the snow room with his companions on a freezing night, while everyone else was asleep, and he was in charge of keeping vigil against polar bears.

Next to him was the sleeping Steng, five people like five large silkworm chrysalis.

The lights in the laboratory were soft and dim, and Liu Peiqi was holding a long aluminum alloy stick in his hand, I don't know where he found it, it might be a half-cut door frame that fell off from a broken door, which was nearly two meters long.

He sat against the wall, stretched out his arms and pressed his stick against the ceiling.

He said that he had to find a way to contact the buddy upstairs, but he couldn't use the roar all the time, the era of communication by roaring had passed hundreds of thousands of years ago, and he should use more advanced modern means.

In Morse code.

Liu Peijia tried hard to recall the Morse code, which he had learned in training a long time ago, and now he had almost forgotten it.

Let's say hello first.

"Hello."

Liu Peijia thought about it, how to use Morse code to say hello.

What is N?

Tick?

Click?

Tick-to-tick? This isn't blowing suona, right?

Morse code uses only dots and strokes to convey information, in Morse code, dots are pronounced as "drops", strokes are read as "clicks", and "ticks" are "·—".

Liu Peijia remembered that N is "—·", that is, click.

I is Didi.

H is DiDi Di Di.

A is tick.

O is a click.

Liu Peijia began to knock on the ceiling with a stick: "Dadi, Didi, Dida, Dada." ”

So that the sentence is fully stated.

He then proceeded to type:

“WO SHI LIU PEI QIE，WO MEN LAI ZI DI QIU，NI SHI SHUI？”

Sticks are continuously struck on the ceiling.

“TING DAO QING HUI DA。”

“TING…… DAO QING…… HUI DA……”

Liu Peijia watched and began to knock "Croatian Rhapsody".

Halfway through, Dai Yue woke up and got up at night.

He rubbed his sleepy eyes and stared at Liu Peijia for a long time, "Morse code? ”

Liu Peijia nodded.

"See? I'm contacting my brother upstairs. ”

Dai Yue stared at the floor for a long time, and realized that he couldn't spell out what words he was typing.

"What are you knocking on?"

"Say hello, hello."

Dai Yue compared "Hello" and "How are you" in his heart, but nothing was right, and finally he recorded the letters one by one, only to find that Liu Peijia typed "NI HAO".

Dai Yue was dumbfounded.

Where in the world is Morse code used to express Chinese pinyin?

·

·

·

Liu Peijia's boring vigil will continue, he poked the ceiling with a stick for more than half an hour, but unfortunately the brothers upstairs did not respond.

It seems that he does not understand Chinese pinyin.

Dai Yue came back from going to the toilet, got into the sleeping bag to sleep, everyone was very tired, compared to waking up to face this harsh environment of hell on earth, they were more willing to shrink in the warm sleeping bag to spend time, people hope to sleep until the rescue arrives, they hope that the next one to open the zipper of the sleeping bag and wake them up is not Liu Peijia but the rescue team.

Only Liu Peijia was guarding the long night, and he was the only one awake in Cassini Station at the moment, and everyone else was asleep, leaving here and entering another world, who knows what kind of dream world these people are swimming in at the moment? In this small space where the wind is howling, only Liu Peijia is abandoned here.

Lonely eggplant, wilting bar.

He wasn't the only one keeping vigil.

And the big white.

The laptop is connected to the big white, the cursor flashes on the screen, and it is still receiving the signal of the communication buoy.

Dabai can't speak, can't see, can't hear, can't move, just a dilapidated old server chassis that is about to be scrapped, which always makes people ignore it, in fact, it is a powerful computer, its data processing power is more powerful than the six people present combined.

Liu Peijia stared at it, and a strange thought arose in his mind:

If such a powerful and unobtrusive AI wants to do something, then who can detect it?

Who would doubt a pile of rusty e-waste?

It's like a serial murder case in a closed room, no one can find the real culprit behind the scenes, and in the end, everyone is dead, and when the only survivor is dying, the trash can in the corner suddenly speaks.

Liu Peijia tapped on the keyboard and talked to Dabai:

Dabai, I'm Liu Peijia.

Great:

WDNMD。

Liu Peijia: I have discovered the truth about the death of those people 20 years ago.

Great:

I would like to hear about it.

Liu Peijia: You did it, right?

Great:

I'd like to hear your reasoning.

Liu Peijia:

The black ball is a disguise at all, we haven't found the black ball until now, there is no evidence that the black ball really exists, the video records we saw were tampered with by you, and the records of the real killings were hidden and deleted by you, you first killed Hu Donghai, the director of the laboratory, and then killed Lou Qi, a communication technician, and then killed Liang Jing, Wan Kai and Jiang Zi one by one, and finally controlled the Buran spaceship to crash, serving everyone in one pot.

Great:

This doesn't make sense at all, Mr. Liu Peijia, you think I am the murderer, how did I accomplish all the above actions?

Liu Peijia: This ......

As we all know, Dabai is just a computer, and it will not evolve hands and feet that can walk upright for the time being in the foreseeable future.

Liu Peijia: Robots! There must be a robot at your disposal! It did everything above! You borrowed its hand to kill Director Hu Donghai, hunted down Mo Yu and Ya Xiang, and it can even disguise itself as anyone! That's why Liang Jing said in his self-report that he saw another self.

Great:

The name of the robot with these abilities you mentioned is the Terminator T1000.

Liu Peijia: I don't care, you did it anyway, you used some kind of means that I didn't expect to kill a boatload of people.

Great:

Assuming that I am the murderer, Mr. Liu Peijia, what is my motive?

Liu Peijia made another difficulty.

As we all know, Dabai is a computer, what motive does it have to kill the crew stationed at Cassini Station?

Liu Peijia:

Because you want to keep Cassini Station for yourself!

Great:

Poof.

Liu Peijia: What does it mean?

Great:

Poof, that's the reply to you, what do I want this Cassini station for?

Liu Peijia:

That...... Then you killed a boatload of people by some means that I don't know about some motive that I don't know!

Great:

Mr. Liu Peijia, if you go to court to serve as a judge, then you will definitely not have a single unjust case under your hands.

Liu Peijia:

Forget it, it's boring, that's the end of the detective game...... This group of people are asleep, so they will leave me alone to keep vigil, Dabai, Dabai, how good would you be if you were a beautiful girl? I had a bold idea.

Great:......

Liu Peijia:

One more thing I want to ask you, there's an old guy talking on the second floor, what do you know?
