"Time and space are real, existing, perceptible, but inaccessible things to us." The lecturer broke off the chalk, then drew a line on the blackboard and marked three points.
.
"Usually, our concept of time is like this line, and the three points I marked, which divide it into past, present and future."
The friction between the chalk and the blackboard left six very powerful Chinese characters.
"The past, just like before these six words appeared, can be regarded as the past. Now, every word I say now is the present, but it is also becoming the past, and the future... the future is vague and not specific enough.
It’s like none of us knows what strange things we will eat in the cafeteria at noon today!”
The students in the audience laughed.
"But there is a question worth thinking about." The lecturer picked up the blackboard eraser and erased the six words, and then said: "Assuming that this blackboard eraser is powerful enough to restore the blackboard to a state where no words have been written, then at this time
, does this line belong to the past, the present, or the future?"
The students were asked.
This problem is really...somewhat complicated...
The lecturer smiled with satisfaction after seeing everyone lost in thought. He said, "Are you all confused? There is no answer?"
Scanning the crowd from the podium, the students were talking quietly, but obviously... no one could give an answer.
But just when the lecturer was about to continue speaking, a boy raised his hand.
The lecturer was a little surprised. He motioned the boy to stand up: "Ziyao!"
Wu Ziyao stood up and said: "Teacher, if time can really be regarded as a line, then all events that occur in time should be integrated into the factors of time. Therefore... even if there is such a blackboard eraser,
When you have the idea of erasing the words, time has completed the threefold concept change of past, present and future, that is to say... no matter how powerful the blackboard eraser is, there is no denying the fact that it is the past. You are now erasing
What is lost and left behind is still the present that is bound by time, remains in reality, and does not change all the time.”
These words sound more complicated than what the lecturer just said...
at least……
At least Nan Yingjian was dumbfounded.
She successfully passed through the door, originally thinking that she would enter a strange world where she would encounter many enemies she had never seen before.
But who would have thought.
When the light in front of her was no longer dazzling, what she saw... was actually a school built under a dome.
There are not many students here, and there is only one classroom.
The students sat upright one by one, listening carefully to the teacher's teachings...
But what is taught here is completely different from the classroom that Nan Yingjian knows... What they study is not words... nor basic mathematics... but what she hates the most... time... space...
"Are these the children they asked me to find?" Nan Yingjian couldn't help but feel confused when she looked at these children.
After Wu Ziyao finished speaking, the classroom became lively.
Everyone seemed to understand it all at once... The lecturer was a little surprised, but nodded with great satisfaction.
"Very good, Ziyao's logic is very rigorous...but..."
With a "but".
Wu Ziyao's smile disappeared, and the students in the audience were also stunned.
The lecturer turned around and wiped the blackboard clean, and then said: "But what I want to tell you is that in fact, no matter it is the past, the present... or the future, all these concepts do not exist in concrete terms, that is to say... we usually think about
Although the understanding of time is specific to every real existence, it has never been completely complete and certain, just like...our human language."
Nan Yingjian had a poker face, she felt like her IQ was being rubbed on the ground... Is this human language?
Anyway, she didn't understand it at all.
The students fell silent.
The lecturer turned around and wrote a new word on the blackboard.
"language".
"Now who can tell me what is so special about language?"
Some of the students in the audience were lost in thought, some began to discuss in low voices, and some seemed to have thought of something and were eager to try... But the smiles on their faces soon disappeared again, as if they suddenly realized that their answers were not accurate enough.
…
Anyway, after a long time, no one answered.
Nan Yingjian just sat there bored. She looked out the window and thought to herself: 'Where is this? The Earth? Or Gaia... What should I do next...'
There is no answer. Nan Yingjian has already tried to leave here, but every time she comes back to the same place.
It seems that Lao Wang did not lie...
"Teacher!" After a long time, someone raised his hand.
"Chu Yan, please tell me."
Guan Chuyan stood up.
Just when Guan Chuyan stood up, Nan Yingjian's heartbeat suddenly increased...not because of how beautiful the child was...how amazing...but because something certain in her memory was awakened.
Ziyao...Chu Yan...aren't these two the children that Lao Wang mentioned before?
Is it them?
Then...should I just take them away now?
Thinking of this, Nan Yingjian walked over to Guan Chuyan and planned to take her away without waiting for her to speak.
However, he found that he had become a ghost-like existence. His body could pass through everything and he could not touch anything in front of him.
Nan Yingjian was stunned, then Guan Chuyan said: "I think... the most special thing about language is that it can describe things that do not originally exist."
The lecturer was slightly surprised, with surprise in his eyes. He looked at the girl in front of him.
The girl who joined the class last.
"for example?"
"Well... for example, we would say... there is a table here." Guan Chuyan patted the table in front of her, and then continued: "This is specific, something that exists in front of us, and I conveyed a specific thing in words.
, reality exists! But the problem is...even if I don’t need to say it, just point to this table and everyone will understand it when they see it.”
"Well, continue." The lecturer came to the audience and stood in front of Guan Chuyan.
Guan Chuyan said: "But if there are no tables here, does it mean that I can't convey specific concepts? Think about it, just like the food in the cafeteria that the teacher mentioned just now, there is no food in front of you now, the time is 1o o'clock in the morning, the chefs should
I'm still processing the ingredients, but... through words, I can let everyone remember what those meals looked like, and even imagine what they had for lunch. This is what I want to say... The most special thing about language... it can
Describing something that does not exist is, more generally speaking, like agnosticism. There is not enough evidence to prove it but it cannot be completely denied... Our imagination has given language this special ability, which is to describe, tell, and convey a kind of
Objects or concepts that do not exist in reality! Just like... time... space... These words are our understanding and description of the structure of reality... When we hear time, we will think of many things, many things that exist in reality, and many things that have already existed.
Does not exist in reality... When we hear space... we will realize where we are in space... we will clearly feel the front, back, left, and right... we will begin to distinguish between east, west, north and south... and we will be specific about where we are.
Is it rising or falling in space...relative stillness...or perpetual motion..."
After Guan Chuyan finished speaking, there was silence in the classroom.
Nan Yingjian was also shocked... This girl looked about fifteen or sixteen years old... Why did she talk... so...
Amazing... Nan Yingjian felt that she was really at a loss for words... she couldn't find the right words to express her mood at the moment.
Others in the classroom expressed their feelings in more direct ways.
"Pah...pah...pah pah pah..." The lecturer took the lead in applauding, and soon the whole classroom burst into applause.
Guan Chuyan's pretty face turned pink, looking a little shy.
Although Nan Yingjian didn't quite understand what the girl said specifically...but she seemed to understand the specialness of language, or...she realized the greatness of language, or...the greatness of human beings.
"Warning! High psionic energy waveform response detected!"
The alarm sounded on the front line.
The adjutant, who had just returned from rescuing the Tornado, suddenly woke up. When he opened the data, his face instantly became extremely ugly...
"Everyone! Enter level one combat status! Prepare to fight!"
The order is issued.
Soldiers in various positions began to get busy.
The King Crab class heavy tank entered operation first.
The alarm also sounded inside the King at an altitude of 30,000 meters, the hull began to "split", and the main gun moved to the predetermined position.
…
"Everyone, hold still!!!" The Defender-class mecha combat formation was on standby at Position 1. The captain spit out his cigarette butts and shouted to everyone.
Time, at 4:15 on February 22, 150 Era, the alien species began to attack human positions in a large scale.
Less than fifteen minutes after the alarm went off, the ground began to vibrate significantly.
This was not caused by an earthquake or blanket bombing.
Rather, it was a surging formation of nearly a million alien species...
The air formation has entered the predetermined combat position. No. 77 is a member of the bombing group in the formation. He is flying a "Veuve Clicquot" type 3 bomber, which is currently the main bomber type in the military formation of the Glorious Republic.
The current altitude is 1,500 meters.
The visibility was good, and after O77 completed the standard operation, he began to inject himself with strengthening agents, which would help him maintain a perfect state for a longer period of time in the following battle.
But when o77 saw the alien army crossing the valley and covering the white snowfield in the distance into black, his heart rate still increased abnormally.
…
The adjutant on the front line was extremely anxious at this time. One of the reasons was that there were too many enemies. The most important thing was that no one could deal with the nightmare-level alienated matrix!
But it was useless to rush. When the enemy entered the bombing range, the adjutant gave the attack order without hesitation.
After hearing a series of roars, clusters of flames pierced the night sky... kicking off the battle...
