Postscript - Yi Siyue's confession

……

Knock, knock, knock......

Knock, knock, knock......

A very rhythmic knock on the door woke up Ye Chang, who was still asleep, he opened his eyes slightly, sat up from the single bed covered with white sheets, and turned his head to look out of the window separated by several iron railings. Pen % fun % Pavilion www.biquge.info

At this time, the sun was already hanging high, there were hardly a few white clouds in the blue sky, and the gentle wind blew through the artificially planted ornamental trees outside the window, and the leaves on the trees made a pleasant "rustle" sound - it was a sunny and good day.

"Dr. Ye, are you up?" A middle-aged man's voice came from outside the door.

Ye Chang was a little dazed, and then said lightly: "Come in." ”

Squeak-

The door opened, and a middle-aged policeman in a blue police uniform walked in from the outside, it was Officer Liang.

"Dr. Ye, are you still in the habit of living?"

"Oh, that's good...... The prison conditions were so much better than I had imagined. ”

"This is the highest-level guard room specially prepared for you." Officer Liang responded politely.

"What time is it?"

"Half past nine in the morning."

"That's ......," Ye Chang muttered.

"By the way, Dr. Ye, please come with me." Officer Liang seemed to think of something and said.

Ye Chang looked at Officer Liang's somewhat bald head and frowned: "Isn't the public trial two days later?" Where are you taking me today? ”

"I was also entrusted by Chief Gu, please go to a place."

"Oh? By the way, speaking of which...... I haven't seen Officer Gu in the past few days. ”

"Chief Gu has already flown abroad on a business trip a few days ago...... Before he left, he asked me to show you something. ”

"What's that?"

"You'll find out with me."

Ye Chang stared at Officer Liang for a long time, and finally nodded with a flat expression and followed him out of the guard room.

Seeing that he agreed, Officer Liang took off a pair of alloy handcuffs from his waist with some hindsight, lit up at Ye Chang, and said slightly apologetically: "I'm sorry, Dr. Ye...... We have rules here......"

Ye Chang didn't have any intention of being annoyed or angry, he raised his hands expressionlessly, and said, "Copy it, although I don't think it's necessary at all." ”

At the end, he added as if to himself: "The world is so big, even if I escape, where can I escape?" ”

……

Soon, Officer Liang took Ye Chang to a dimly lit room, and when Officer Liang casually closed the door, the whole room became pitch black.

But soon, the wall facing the two of them gradually lit up, and in front of them was a huge LCD screen, which took up almost half of the center of the entire wall, and as the light became brighter and brighter, the layout of the whole room gradually became clearer.

Ye Chang saw the seat placed on his left side, and Officer Liang on the side looked at him, pouted in the direction of the seat, and made a "please" gesture in his hand, signaling that he could sit down.

"Excuse me...... Are you going to show me some movie? ”

"No...... Not a movie. Officer Liang shook his head: "It's a video left by Miss Yi Siyue before she died." ”

How did you know that when Ye Chang heard this, he didn't say a word, turned around and left.

"Dr. Ye!" Officer Liang grabbed Ye Chang's shoulder: "Chief Gu personally instructed me to show you this video." ”

"In the video, it is nothing more than an explanation of the layout of the whole case and my intentions." Ye Changtou didn't reply: "I've already heard this from Officer Gu, and you relied on this video to find me, didn't you...... What's there to see? ”

"No, it's not." Officer Liang said in a condensed voice: "Miss Yi Siyue did leave a video that carefully explained all the details of the crime and the motive, which is also the most critical help for us to make you plan your miscarriage...... Just ......"

"Don't you want to know why she left this crucial piece of evidence?"

Ye Chang was silent for a while, then lowered his head and said coldly: "Maybe she doesn't believe that there is an invisible ceiling in the universe at all......"

"At first, we thought it was because Miss Yi Siyue might have doubts about your theory...... Or can't bear to watch the world fall into endless war, and your conscience has found it, leaving evidence to stop your plan......" Officer Liang hesitated for a moment, and said slowly: "Until we saw the second video......"

"The second video? What is that? ”

"In fact...... Miss Yi Siyue left two videos before her death...... Another video, which is reserved for you. ”

Ye Changhuo turned his head and stared at the gradually clear LCD screen.

……

"Hmm...... Can you see it? ”

Several white fingers appeared on the screen, and after the camera shook violently for a while, the picture gradually stabilized, and in the middle of the camera, a mature woman with a delicate face stood.

Her skin is very well maintained, although there is already a bit of vicissitudes in her eyes, but her delicate facial features and slightly ruddy cheeks in her fair skin make people mistakenly think that this is just a beautiful girl in her twenties.

The woman smiled at the camera in front of her and said, "Ye Chang, hello, I'm Yi Siyue." ”

"I don't know how you're going to see this video...... In fact, I'm not even sure who's going to get this video......"

"Have you watched "White Night Walking"? The night we last met, I told you what to watch...... This is my favorite novel. ”

"If you really understand the meaning of my words, maybe you can go to my mother and get the "White Night Walking" novel with my autograph, and with your ingenuity, it will not be difficult to find these two videos in advance by following the clues......

"But...... With your personality, even if you really want to read a novel, I'm afraid you will go directly to the nearby bookstore and buy a copy, right? Then you won't be able to see what I'm arranging. ”

"But the best outcome is that after I die, the police investigating the cause of my death find these two videos, and if that's the case, then thank God."

"Speaking of which...... Allow me to extend my sincerest apologies to you. ”

Yi Siyue in the lens stroked the hair between her sideburns at this time and bowed deeply to the camera.

"Although I have been involved in your plan from the beginning, I have no selfish desire to make you truly successful......"

"But don't get me wrong, I'm not questioning your 'ceiling hypothesis'...... On the contrary, I think that the hypothesis you have proposed has a very solid theoretical basis. ”

"Technological stagnation due to the limitations of people's thinking has led to the gradual depletion of resources and the extinction of human beings...... This is the 'invisible ceiling'......"

"As cruel and reasonable as it sounds, perhaps we humans will indeed face such a dilemma in the near future...... I'm convinced of that. ”

"So please don't look at me as a 'betrayer', I'm the strongest supporter of the 'ceiling theory'."

"In that case, why should I leave evidence in an attempt to subvert your plan?"

The woman in the video was visibly slightly stunned, and then said, "I think the 'invisible ceiling' is real...... In science, there will inevitably be technical barriers that cannot be broken through conventional methods because of some of our thinking limitations......"

"We may also really be dying because of the existence of technical barriers."

"But...... Did we, who put forward the ceiling theory, completely break the ceiling that pressed on the top of our temple of thinking? ”

"Ye Chang, you often say, 'Survival is the first need of civilization'. Seems to make a lot of sense......"

"If there is no guarantee of survival, what is the point of human civilization, no matter how magnificent and brilliant it is?"

"But...... But ......"

Yi Siyue's voice became a little trembling.

"But...... Could this kind of thinking be an alternative '1+1=2'? ”

Seeing this, Ye Chang's right hand suddenly clenched into a fist.

"According to ceiling theory, in mathematics and physics, self-evident axioms such as 1+1=2 are probably not applicable to higher stages of scientific research...... It is also a self-evident axiom that survival is the first need of civilization...... Could it be that it will not apply to the future, or even the present human race? ”

"When we think we have broken the ceiling of science, will we still be trapped under the ceiling of human nature without knowing it?"

"Ye Chang, you don't understand people's hearts."

"I've spent most of my life exploring the secrets of the human mind, which is why I majored in psychology in college...... The more I delved into it, the more I felt that the human mind was more complex than any formula and theorem in the world. ”

"Is there really an insurmountable limit to the human mind, I think it should be."

"The human nature that I have seen is actually short-sighted and selfish, and human beings are often unable to really peel their perspective out of their own bodies and look at the bigger world."

"It's not so much a limitation of thinking as it is a distressing clumsiness inherent in us human beings."

"Such clumsy human beings, they are running hard for a living, and they are confused for a good stomach...... There are always a few people in this world who don't have time to think about the problems you have been puzzled about, and they have done their best just to live. ”

"But the strange thing is that it is such a group of people who are just 'alive' who are often able to inadvertently reveal a small overlooked, but indeed existential greatness. They can also embody all the good qualities of human beings in certain moments. ”

And in the face of such an ugly, yet glorious human heart...... Can we really simply think that survival is the ultimate pursuit of every emotional individual? ”

"I know, I know what you're trying to say...... Once the perspective is raised to the level of human beings as a whole, the experience of the individual is no longer applicable, but isn't the so-called human whole made up of such living individuals? ”

"I firmly believe that there is something more precious in every human mind than life, and if this is the case, then the 'first need' of humanity as a whole cannot be represented by a single 'survival'."

"Ye Chang, this world is too big, countless people will have different definitions of the most precious in their minds, I understand that it is difficult to change your stubborn thoughts with words alone, since this is the case, then I will use practical actions to convince you."

"It is with this in mind that I have devised this interlocking ruse for you."

……

"Do you know why I sacrificed my life to help you complete this plan?"

"Actually, I am not noble at all, I am not thinking about the future of mankind as a whole, nor is it simply for the development of science and technology...... Ye Chang, I am not a pure martyr. ”

"I just want to be able to tell you by my actions that someone is willing to give up what you think is the most important 'right to live' for the sake of something."

"And I'm sure you'll end up abandoning this seemingly supreme right to exist just for the sake of your illusory ideals."

"So are you an idealist? I don't think so. ”

"You simply think that the development of physics is much more important than your life."

"You're just...... Just choose the option that's better for you. ”

"So do I."

……

"As for what it is that would make me give up my life......"

At this time, Yi Siyue, who had been calm and calm in the camera, turned a rare red, she seemed to have mustered up enough courage and smiled:

"Remember the first time we met?"

"Both of us were in elementary school at the time, and since you lived next door to my house, we used to climb on the roof of the house at night, and you would always point to the stars in the sky and explain to me what the 'Fermi paradox' was."

"I was so stupid that I couldn't understand a word of what you said, and whenever I looked confused, you would squint your eyes and giggle at me."

"Then the greatest rival in my life appeared, and physics took you away from me, and since then, you have never accompanied me to see the stars at night."

"What you may not know is that every weekend, when I go back to my mother's house, at night, I will always climb to the roof of the house alone, sit where you and I used to sit, look up at the starry sky, and then I will always learn from you to squint your eyes, giggle, laugh and laugh, tears will flow involuntarily......"

"It turns out that the so-called ceiling of human thinking was broken by me more than 20 years ago. Survival is no longer my first need, it is above survival, above everything in my life......"

"It's you."

"It's just you."

……

"What a privilege it is for me to meet you in my short life?"

When Yi Siyue said this, she slowly turned her back, only the slightly shrugging shoulders and the almost choked voice revealed her mood at this time......

She muttered in an almost inaudible voice:

"Ye Chang ......"

"I love you."

……

End of "The Invisible Ceiling".
