In the empty recuperation room, there was no sound except for the occasional "ticking" sound on the instrument wall.

Although with the departure of Xingchuan, the instrument wall has returned to its original position again, and has successfully isolated Li Si's line of sight from Li Qiu and Zhuang Xu, but after the "abnormal signal", the courage warehouse of the two is now empty, and it will take a while to fill it.

Blinking his big eyes at the warm yellow above his head, Li Qiu's heart was full of melancholy.

It's like a time back in space, and I can't think about it or say it......

No, it's worse now than in the space, where there are still breaks and a diary full of bugs.

Speaking of journals......

"It's over......" Li Qiu lamented in his heart, "I started to think involuntarily again......"

"Li Qiu, forget it, anyway, judging from what Star Legend said just now, they shouldn't be able to decipher what the message we are transmitting is."

"They can't be deciphered, but they can be stored! If they master the deciphering technology in the future, then we will have to be slaughtered? ”

"Have you forgotten that we still have Zou Miao, a so-called ally?"

"That's right...... Eh, Zhuang Xu, I remember you seemed to say that you made hardware before? ”

"Yes, but I've only graduated for a year, so I don't have much practice."

"This doesn't matter, I just want to ask, what's going on with the receiver that Star Transmission said before?"

"Well...... Zhuang Xu organized the language in his mind, "That's right, whether it's a discrete signal such as an electrical signal generated by an electrical circuit being turned on or off, or a continuous signal generated like we speak normally, these signals are all transmitted through the carrier.

The network cables that we usually use to transmit network data, or the kind of cables we see outside, are artificially made transmission carriers, and those who transmit signals in this way belong to wired transmission. But like Bluetooth, or what they said before, we install a receiver on us to receive signals in a specific frequency band, and this way of using electromagnetic waves to propagate signals in space belongs to wireless propagation. ”

"And what does Lees mean by transformation?"

To put it simply, the process of a signal from transmission to reception can be divided into three parts, the transmitting end, the transmission channel, and the receiving end. The transmitter is responsible for changing the signal into the most easily propagating form and then transmitting it, and the receiver is responsible for restoring the signal that has been modified by the transmitter and interfered with by the transmission channel to the original signal as much as possible.

In the case of a continuous signal such as speech and a discrete signal such as data, the receiver on the artificial human body should have at least an antenna part for receiving the signal, a demodulation module to remove the original signal from the high frequency, a decoding module to remove the redundant coding added to ensure the correct transmission of the signal as much as possible, and a digital-to-analog conversion module to convert the electrical signal into an analog signal such as the original voice. ”

"Then according to what you say, the transmitter and receiver are doing completely opposite things, so don't the two of us have a lot more parts on us than the young master?"

"No, first of all, the antenna part can be reused, followed by the digital-to-analog conversion module, for artificial people who need to process digital information and voice information at the same time, digital-analog bidirectional conversion is a necessary function, as for the encoding, decoding this part, since there is already a decoding module, the hardware part must be satisfied, add a few lines of code to the program to increase the coding function, and finally the modulation corresponding to the demodulation, this does need to change the hardware, but the added components are definitely not as many as you think."

"That's it......" Li Qiu thought for a moment, and then his eyes lit up, "Zhuang Xu, I have an idea now, you can help me think about how to verify it." ”

"You say."

"I think the telepathy between the two of us should be the result of the system's programming. Because according to you, signal transmission requires program decoding and antenna transceiving, that is to say, our systems may default to the open state of the transceiver channel between the two of us, so if we turn off the channel through commands, won't there be no more telepathy? This way, Obsidian will no longer be able to capture the call between us. ”

"yes, I didn't think of that!"

Li Qiu's words made Zhuang Xu instantly enlightened: "Li Qiu, let's try to call the system in our body." ”

"Oh yes, the system!" Li Qiu also reacted, "I remember, Obsidian said before that it couldn't connect to our system, okay, then let's try it separately." ”

Li Qiu, who had a clear goal, was suddenly full of fighting spirit, she first tried to close her eyes and look inward in Xiuxian, wanting to see if she could see a light screen similar to a computer screen in her body through this method, but no matter how she took a deep breath and held her breath to concentrate, it was always dark in front of her.

If this road doesn't work, then change the road.

Li Qiu began to try to communicate with his system by greeting again.

"Hello? My name is Li Qiu, the autumn of spring, summer, autumn and winter, what about you? ”

In my mind, except for the "Hello" and "Empty Wow" from Zhuang Xu's side from time to time, it was quiet, and there was no movement at all.

Li Qiu, who did not give up, continued to shout: "Although people say that they are more timid about their hometowns and dare not ask who comes, but the two of us will live together for a lifetime, and we can't play this kind of "awkward game", in case something big happens because of the lack of understanding, it will be over, you say, right?" ”

Except for Zhuang Xu's "Stupid Pig" and "Savadika", the night of the military port is still in my mind - quietly.

Li Qiu's brain was pumped by Zhuang Xu's shouting, and he suddenly yelled in his heart, "Don't hide inside and keep quiet, I know that you are at home, you have the ability to open the passage, why don't you have the ability to come out to meet people!" ”

Zhuang Xu's side was finally quiet, he was shocked by Li Qiu's roar, and after a long time, a weak sentence came out, "Ah Niu Hase?" ”

“……”

Li Qiu was tired, she relaxed her body and quietly stared at the warm yellow light above her head, only to feel that the past around her was all passing by and was not worth caring about at all.

At this time, she suddenly began to miss XY035 in the space.

I don't know how he's doing now......

Obsidian said that the entrance to space 3 was automatically locked so there was no forced entry, so should XY035 still be alive?

Thinking of Obsidian's previous report to Xingchuan, Li Qiu suddenly chuckled, "I don't know if I'm 01 or 02, whether it's a man or a woman......"

"Drop-01 greets you, what instructions do you have now?"

"Drip - System 02 greets you, what instructions do you have now?"

Listening to these two voices that sounded almost at the same time, Li Qiu and Zhuang Xu were stunned.

They tried hard for so long, and in the end, the names of these two systems turned out to be so simple and natural.

It's just that although Li Qiu did shout No. 01 and No. 02 at the same time, it stands to reason that the system shouldn't just follow the orders of the body owner?
