Chapter 781 Sound Sequence (Two in One)
In the kitchen, everyone sat on low benches, holding bowls of porridge and drinking, so that the lower abdomen of hot porridge could slightly dispel the chill.
As soon as Xi Shuangyu put down the bowl, she immediately urged: "Miss Ling, tell me quickly, what does it mean? What does it mean? "
Liu Sheng raised his head and drank the last bite of porridge in the bowl, gently put down the bowl, raised his hand to light up the spiritual information, and a light screen projected out.
As the light screen appeared, the noise echoed in the house again, and a undulating wavy line was displayed on the light screen.
"This is a waveform diagram of the sound." Liu Sheng said lightly.
Except for Qingxue who had heard Liu Sheng's sharing, everyone else was slightly stunned. Obviously, they did not expect that the sound could be presented so intuitively.
In contrast, they listen with intuition, which seems a bit too primitive.
In addition, why are other people’s spiritual information so advanced?
Everyone looked at the spiritual news in Liu Sheng's hand and felt a little jealous.
"But... I can't tell anything just by doing this..." Xi Shuangyu frowned and thought.
"If this is the case, of course it won't work." Liu Sheng said calmly, "but all information can be disassembled into the most basic unit, and simplified in the complex, and perhaps it can be understood."
She tapped her fingers, and the waveform on the light screen enlarged, and her fingers crossed the highest and lowest points.
"If 'one' is used to represent the high point, 'zero' is the low point..."
"Wait," Guo Yishou frowned and interrupted directly, "Why have to use 'one' and 'zero'?"
He cares more about this.
"Because this is binary." Liu Sheng explained softly.
"Binary?"
Everyone murmured and repeated, not understanding.
"...Binary is the most basic encoding method, which can store and transmit any information in the simplest form. Just like when you practice, you must dismantle the huge mental method into core characters and then combine it and use it, the same is true for information."
After Liu Sheng explained why the binary system was, a series of numbers immediately appeared on the light screen, constantly scrolling endlessly.
"But in this case, is the sound just a simple waveform converted into a sequence?" Qiu Jingyi asked thoughtfully, "If so, wouldn't the original sound levels be lost? The sounds we hear are layered and layered, which is much more complicated than this."
Liu Sheng nodded slightly, with a deep look: "Yes, the real complexity does not lie in the waveforms themselves, but in its multi-dimensional projection."
She flipped her hand, and the waveform on the light screen suddenly began to deform, as if it had broken away from the limitations of the plane, gradually turning into stacked waves surging in the kitchen.
Those sequences quickly dissipated into longer chapters.
Everyone widened their eyes, and the waveform in front of them looked like a brocade that was constantly folding in the air, becoming more and more complicated and twisted, and the lines were entangled together, which was dazzling.
But here they understand a little why they hear more and more distorted...
"These signals may not be what we hear at first. They originate from higher dimensional spaces. When projected into our world, they must be folded, distorted, and even some information may be hidden or obscured." Liu Sheng explained, "That is why we are so difficult to understand and difficult to decipher."
"Like a shadow?" Qingxue suddenly realized, "The human shadow fell on the ground, and information on gender, appearance, age, etc. were omitted, leaving only a black outline."
"That's true." Liu Sheng nodded, "but unlike simple shadows, there may be 'topological folding' in the process of dimensionality reduction of these information, that is, contents that were originally far apart may overlap due to projection, while the originally coherent information may be dispersed after dimensionality reduction."
With a wave of her finger, the waveforms on the light screen instantly shattered, turning into countless scattered fragments, interlaced and spliced together, like a cut page.
Xi Shuangyu couldn't help but feel a little discouraged: "Isn't this even more difficult?"
Liu Sheng smiled: "So, it is not enough to just use linear decoding. We need topological mapping to restore these fragments to the original structure."
"How to do it?" Qiu Jingyi couldn't help asking.
Liu Sheng pointed lightly, and a complex set of information networks immediately appeared on the light screen. Some of the bands flashed and seemed to be related to each other, but they broke due to dimensionality reduction.
"First of all, we need to find the pattern of repeated occurrence, just like ancient book proofreading. If the two similar texts are different, there may be a copying error. Similarly, if some pattern combinations appear repeatedly in different time periods, we can speculate that they may belong to the same piece of information, but they are broken up after dimensionality reduction."
"Secondly, we need to reconstruct its spatial location." She points to certain staggered bands. "These signals are distributed far in the spectrum, but they are in some topology, perhaps originally adjacent, and we can try to restore them."
As she operated, the signal lines on the light screen gradually interlaced and closed, as if they were pieced together a complete scripture.
"Can you fight back this... actually fight back?" Guo Yishou couldn't help but exclaim.
Liu Sheng smiled indifferently: "Of course, this requires a lot of calculation and comparison. I only found a part of it if the time is limited."
Of course, this is just her conservative statement.
She doesn't want to expose too much.
A longer string appears on the light curtain.
"We assume that certain specific signal patterns correspond to a certain language unit, like a ciphertext - if we find the rules in it, we can translate this information."
"But... the sequence formed by these sounds should be vast, right?" Qiu Jingyi frowned.
"Yes, so we have to collect and compare."
Liu Sheng nodded, and a large number of dense symbols were projected on the light screen, as if they were some kind of ancient scripture, which looked complicated and unspeakable.
"This is a corpus I have compiled, and we can use it to match the patterns that appear repeatedly in the signal."
She pointed to the text on the light screen.
"For example, these syllables have the highest repetition rate, and they are very likely to form basic grammatical units, similar to common meanings such as 'yes', 'no', 'you', and 'me'."
Everyone held their breath and concentrated, gradually attracted by her explanation.
"Just like we crack ancient books, we cannot directly understand a whole strange language, but if we find the meaning of certain keywords, we can piece together the meaning of the whole sentence bit by bit."
The string of strings composed of "one" and "zero" on the light screen is gradually matched and parsed.
Finally, a short line of text slowly emerged:
Don't answer! Don't answer! Don't answer!
I don’t know when there was only silence left in the kitchen.
They held bowls one by one, but didn't drink porridge, just opened their mouths-
It seemed that he was shocked by Liu Sheng's fancy operations, and it seemed that he was constrained by the short warning on the light screen.
"So..." Xi Shuangyu's throat was slightly dry, and she had difficulty speaking after a while, "What does this mean?"
Liu Sheng shrugged: "Maybe an unknown existence is warning us, a warning that transcends dimensions and time."
"Can this be so?" Li Chu murmured in a low voice, "Gaowei? Where is it?"
Zhang Chengling's face was slightly pale: "I can't answer, what is the answer to?"
"Enough!"
Guo Yishou suddenly slapped the bench, and the heavy sound woke everyone up to their thoughts.
"It's just a word, don't scare yourself!"
Although his mouth was tough, his face was pale. "Guo Yishou is right." Liu Sheng suddenly answered.
Guo Yishou was stunned. Unexpectedly, Liu Sheng would agree with him and couldn't help but look slightly.
"Don't over-speculation, we have too little information on hand."
Liu Sheng's eyes slowly swept across everyone's faces, and his tone was still calm.
"We can't even be sure whether this warning is for us, or for... some people earlier, or... others."
Of course, only Liu Sheng knows whether this sentence is comforting or not.
Everyone was just silent, and the porridge was rumbling on the stove, just like their restless hearts.
"Okay." Liu Sheng raised his hand and waved his hand, and the scrolling characters on the light screen dissipated. "Next, follow my arrangements and guarantee that you can all join Senior Nangong's training camp!"
Everyone immediately cheered up.
"Of course, if you want to do a good job, you must first sharpen your tools, so more importantly, we need to transform this Tianyin receiving device..."
The newest ⊥Xiao⊥Speak⊥Send⊥Six⊥9⊥Book⊥⊥⊥⊥Back⊥⊥⊥⊥!
"Based on this design drawing."
Everyone's eyes became brighter, and they dared not miss a trace of details.
On the light screen, a very finely drawn sketch slowly unfolded.
It was a huge arc-shaped bowl, facing the sky, like a huge eye gazing at the starry sky, and like a lake, standing quietly in the valley.
Liu Sheng pointed to the structure and constantly enlarged the details to explain:
“…The overall surface can capture more and wider information. If necessary, we can adjust it to the right angle so that we can more effectively capture signals in specific frequency bands while reducing noise interference…”
Finally, he clapped his hands and raised his lips slightly:
"Then we can complete the tasks assigned by Senior Sister Nangong...the senior. How about it? Isn't it very simple?"
However, there was only a more silent air that responded to her.
After a while, Qingxue came to her senses first, silently picked up Liu Sheng's empty bowl, served a bowl of hot barley porridge again, and handed it to Liu Sheng with both hands.
"Although I don't understand it very much... it doesn't matter. In short, just follow Sheng Sheng!"
...
So, in this snowy valley, action began in full swing.
In order to improve efficiency, the six people were divided into two teams.
Qingxue, Zhang Chengling and Li Chu were responsible for establishing the corpus.
Xi Shuangyu, Qiu Jingyi and Guo Yishou buried their heads in building what Liu Sheng called the "Tianer Lake" in the wind and snow.
"Why is this thing called Tianer?" Guo Yishou put down his hammer, looked at the already spread out Tianer Lake, frowned, "It looks more like an eye, shouldn't it be called Tianer?"
"I don't know... Miss Ling seemed to say something that was taken away by the name. I don't understand, but her name seems to be quite vivid."
Xi Shuangyu shook her head, her eyes shook by the silver light reflected from Tianerhu, but the corner of her mouth couldn't help but curl up.
"She always says something that makes people unable to understand." Guo Yishou complained in a depressed manner, "I don't know where the strange man came out of a corner."
"I heard that she came from the National Academy."
Qiu Jingyi couldn't help but join the gossip.
He connected the panel with a welding spiritual weapon to the edge of another piece. The scorching fire made him sweat in this snowy day, so he could only raise his hand to wipe it.
"The weird guy from the National Academy." Guo Yishou defined it firmly.
"Don't say it, maybe Miss Ling can hear it?" Xi Shuangyu reminded in a low voice.
"Junior sister, don't talk nonsense. How could she hear us from this far away?" Qiu Jingyi shook his head and smiled.
"But..." Xi Shuangyu frowned, as if she was thinking of something, and said hesitantly, "She always seems to have done anything to us clearly and point out any mistakes in time. She always feels...it seems to have eyes and ears installed on us."
"If she could really hear it, then she would be a god!" Guo Yishou looked disbelief and sneered.
In the corner where the three of them were invisible, a small golden ear that was buried under the panel trembled slightly and then quietly shrank back.
In the house on the other side of the ridge, Liu Sheng was checking the model written by Qingxue. When he heard these discussions on Tianer Lake, he couldn't help but smile.
"What's wrong? Shengsheng, did I make a ridiculous mistake?" Qingxue immediately became nervous when she saw Liu Sheng's smile.
Zhang Chengling, who was confident, quickly took the notebook back and checked it carefully.
Liu Sheng shook his head, "No, I just laughed at the sound of the wind in the valley."
Qingxue stared at her suspiciously, and after a while, she curled her lips: "Shengsheng loves to joke..."
Although she said this, she felt relieved. She temporarily let go of her heart, but her eyes were still staring at Liu Sheng's expression.
After a while, Liu Sheng closed the notes in his hand and showed a faint smile: "Well, the model is fine. You have learned it and you can work with me."
Qingxue's heart completely fell back to its original position, and a huge sense of accomplishment suddenly surged into her heart. She rushed over without hesitation and hugged Liu Sheng.
"It's so good, thank you, Shengsheng!"
"Don't worry, this is for you."
Liu Sheng blushed and broke free from Qingxue's arms, took out an iron pot full of exquisite runes for Qingxue.
Qingxue exclaimed, "What is this?"
"You will know if you put it on."
"Oh..."
Qingxue was well-behavedly on it, but after a while, her eyes changed, and she was shining with strange obsession.
When Zhang Chengling saw it, he immediately handed over his notebook: "Miss Ling, look at me."
Liu Sheng checked for a while, nodded and said, "You can do it too."
So he also gave Zhang Chengling a sip of the exquisite iron pot.
Li Chu saw them all bringing pots and utensils, which looked ridiculous, but they seemed to have a strange feeling, as if they had entered a mysterious state.
He looked down at the manuscript he had only written halfway through, and a hint of anxiety appeared in his eyes. How could he laugh?
He can't fall behind!
For the sake of this shiny iron pot, ink traces quickly crossed the paper, and the writing speed suddenly accelerated a lot.
...
Time passes by like a flash, and a month passes in the midst of wind and snow and busyness.
Finally, it is the day to accept the results.
