I rely on tricks to cultivate my longevity

Hearing "binary coding and decoding", Bai Qing didn't react at all, but the title "girl" seemed to irritate her.

She stomped her feet angrily and argued, "I told you I have a name!"

"Okay, Ah Qing, are you satisfied!" Lin Xixue smiled helplessly, wondering why Bai Qing's focus is always so strange.

"Well, what are these two horse-making things?"

"Hmm", Lin Xixue clenched her fist with one hand, and pressed it lightly under her nose, thinking about how to explain this problem to Bai Qing.

She first moved her little finger slightly, then violently, and then asked, "Can you feel the difference between these two movements?"

Bai Qing blinked her eyes, she didn't seem to understand her intention, and asked in confusion: "Isn't it just a light and short time, and a long and heavy time, is there anything special?"

"That's right! If we hadn't agreed on something in advance, it would just be a normal feeling twice."

"But if we agree in advance that a short moving finger means 'yes' and a long and heavy moving finger means 'no', wouldn't we be able to complete a message transfer?"

"That's right!" Bai Qing suddenly realized, but then she felt a little lost, "But the information conveyed in this way is too limited, and it's not practical."

"That's right, now we can only pass 'yes' and 'no', but what if we extend the byte?"

"Self-robbing? What is this?"

"Byte. You'll understand when I say that. For example, we used short to express yes and long to express no. They all express a meaning with one finger movement."

"But if we use two finger movements to express a meaning, such as short for 'yes', long and long for 'no', long and short for 'you', and short and long for 'I', can we now express four mean?"

Bai Qing lowered her head and pondered for a moment, then said in shock: "Then if we continue to lengthen the 'self-robbing', won't we be able to express more meaning?"

"Of course, if we extend the number of bytes to eight, we can express 250 six meanings, and when we reach ten, we can express more than a thousand different meanings."

Lin Xixue nodded, very satisfied with Bai Qing's understanding ability.

"That is to say, as long as we agree in advance what this 'self-robbing' means, we can rely on this thread to transmit sound regardless of distance!"

Bai Qing was overwhelmed with surprise, stepped forward to hold her hand, and said excitedly: "Xiaoxue, you are simply a genius!"

"Ahem, it's okay."

Lin Xixue looked away from Bai Qing with some embarrassment, thinking that this is not her wisdom, and the knowledge from her previous life brought to this world is simply a blow to dimensionality reduction.

"Oh, by the way, is there only one pulling wire?" Bai Qing suddenly asked such a question for no reason.

"There are two more." Lin Xixue took out the remaining two traction wires, "What's wrong?"

Bai Qing snatched the lead wire and said: "Why don't I keep this thing for now!"

"Ah, here." Lin Xixue didn't expect Bai Qing to do this kind of behavior for a while, so she couldn't help being dumbfounded.

Bai Qing wrinkled her nose, and said dissatisfiedly: "What? Could it be that you have other uses for this thread? Do you want to communicate with other people?"

"Hiss, isn't there still Zhiyi here? It can't be just the two of us through sound transmission."

"Oh? I think your name Zhiyi is very affectionate. Calling me by my name is like killing you." Bai Qing bullied her, her dissatisfaction even stronger.

Before Lin Xixue could respond, Bai Qing snorted softly, and tied a traction thread between her and Xu Zhiyi's fingers.

"Okay, now that you want to communicate with Zhiyi in the future, I can convey it to you, and you can also save a thread of distraction."

"No, no, no, it's easy to have a man-in-the-middle attack and a single point of failure!" Lin Xixue repeatedly waved her hands in denial.

"What does that mean?"

"The so-called man-in-the-middle attack is...for example, if you are accidentally caught by the enemy, then the information exchange between me and Xu Zhiyi depends entirely on you, so the enemy can directly grasp all the content of our sound transmission?"

"There is also a single point of failure. For example, if you are in danger, Zhiyi and I want to discuss a rescue plan for you, but you can't convey it on your behalf, and the information channel will be broken. This is a single point of failure."

"So! The safest solution is undoubtedly that the three of us connect with each other with a wire to achieve point-to-point transmission!" Lin Xixue explained solemnly.

"Well, it makes sense, reach out!" Bai Qing reluctantly wrapped the last lead wire around Lin Xixue and Xu Zhiyi's hands.

However, it is not enough just to have a clue, a code book is also needed, but the time is running short, so Lin Xixue had to improvise a simplified octet code.

Although it can only express 250 six characters, it is more than enough to simply convey information.

Lin Xixue handed the code book to Bai Qing, and told her to burn it after writing it down, otherwise if the code book fell into the hands of the enemy, she would be able to use it to decipher the information passed between them.

After dealing with all these matters, Lin Xixue and Bai Qing talked about the most important things right now.

"I've been waiting for your reunion in the city for the past few days, and I've mentioned going to the Sanyuan Temple, and I'm going to go to the temple to investigate tomorrow morning."

"Okay, I'll go with you." Bai Qing responded without any hesitation.

"No, there is another very important thing that you may need to keep an eye on." Lin Xixue shook her head, "Hongyanzi's old lair is called Jieshi Cave. Although Hongyanzi is dead now, there is a dead body in the cave." The puppet mother is entrenched."

"This worm mother keeps producing new corpse puppets. Although I have wiped out all these corpse puppets a few days ago, I'm afraid it won't be long before there will be another disaster, so you may need to be on guard."

Bai Qing nodded, agreed, and said: "Then you go to Sanyuan Temple alone, so be careful."

Lin Xixue took out the Sanqing mask and said, "Don't worry, I've already figured out a specific plan for the investigation. This trip will mainly be a secret investigation, and try not to disturb these bull-headed people and avoid conflicts."

After finishing speaking, she told Bai Qing in turn.

"You too, just keep watch near Linghu Village, don't go deep, after Zhiyi wakes up, we will go in together to solve the problem of the bug mother, I have already learned the weakness of the bug mother."

"If there is any change, please contact us through sound transmission!"

"Okay, let's get in touch with Transsion."

"Oh, by the way, I almost forgot to ask a question, why did you return to Xinliang City so quickly?" Bai Qing asked something that she was puzzled from the beginning.

"It's a long story."

"You don't just go to Sanyuan Temple to investigate tomorrow morning. The night is long, so you can have a long talk."

"It's related to evil, it's better not to tell you."

"Okay." Although Bai Qing agreed, she muttered something in her mouth, she didn't know what she said, and then said: "Be careful in everything, I'm still waiting for you to fulfill your promise."

"it is good."

The two looked at each other with a tacit smile and hooked their fingers.

Without chatting any more, Lin Xixue went to take a bath and change clothes. After living on the mountain wall for five days, her body was already covered in ashes.

She changed her clothes, took the Gushen Pill, calmed down, looked at the faint morning light in the sky, took out the mask of three emotions and covered her face.
