So I went to Douluo

Xu Yue watched with interest as the light in the middle-aged man's eyes changed several times, which was extremely exciting.

The middle-aged man who was full of anger and complaints before suddenly put on a flattering expression, sat down again, and said with a bit of flattery: "So you are also our Shrek's professor, we are a family." , tell me earlier!”

But in the face of his flattery, Xu Yue changed her expression and said in a slightly mocking tone: "I said I was an honorary professor, and you believed it? Uncle, you are too unprincipled."

After several pulls, the middle-aged man became immediately annoyed: "You're here to make trouble, right?!"

Xu Yue clicked her tongue: "Uncle, look at what you said, I just asked you a few questions, how come you are looking for trouble?"

The middle-aged man said impatiently: "You should have finished asking now, right? Please leave after you finish asking, and don't hinder my work."

This is not the first time he has issued an eviction order.

Xu Yue listened quietly and chuckled.

"Then let me ask you one last question."

The middle-aged man still looked impatient: "What else do you want to ask?"

Xu Yue raised the corners of her lips: "Then -

"I wonder what your last name is, uncle?"

The atmosphere in the security room suddenly fell silent.

For a moment, the only sound in my ears was the sound of car engines passing by outside the school gate.

After an unknown amount of time, the middle-aged man opposite suddenly burst into laughter.

After a long time, he relaxed his body, leaned back on the chair, looked at Xu Yue jokingly, and said, "My surname is Long, and my real name is Long Yuan."

Xu Yue dragged out a frivolous "ah" and said with a clear smile: "It's a coincidence that your surname is Long, don't you think so?"

Long Yuan crossed his arms and said, "I'm very curious, what is the reason that makes you suddenly doubt me, an inconspicuous little security guard?"

He even locked onto him so accurately.

Xu Yue: "Because I don't believe you can publish something as valuable as an academic journal."

Professor Long Yuyan’s achievements are real.

Long Yuan: ""

He almost laughed out of anger: "Is it because of this?"

Xu Yue smiled slightly: "Yes. But it's just one of them.

"This is a harmonious and stable society, so in fact, there is nothing wrong with your behavior at Shrek, even if you are just a security guard who went to a place you shouldn't have gone."

Long Yuan said with great interest: "Oh? So where did I go wrong?"

Xu Yue: "It's a pity that something is wrong with Shrek now. When nothing happens, your small abnormal behavior will naturally not attract anyone's attention. Once the emergency alert is triggered, any suspicious behavior will be infinitely magnified. In short , you underestimated the power of an entire national machine.”

She smiled and continued: "You know, the moment you talked to Professor Long Yuyan, the life trajectory of your identity has already reached my ears."

Xu Yue tapped her temple with her fingertips.

Long Yuan's expression changed slightly. After a moment of silence, he smiled: "So it turns out that I made too much noise?"

Then he sighed: "You have no intelligence and no other means of communication. Except for the Soul Saint and the two little brats, there is no one else around you. Even so, you still got the news. This is the power of the Star Luo Empire. ?”

Xu Yue showed a noncommittal smile.

Long Yuan snorted and looked at Xu Yue: "However, since you have admitted it, I made a big noise this time. So, have you ever thought about it, now, here -"

He pointed at himself, with a half-smiling expression:

"What are the consequences of exposing me?"

Long Yuan looked at Xu Yue's expression and continued: "Although I don't know how your investigation is going now, I think you should have figured out one thing -"

There was something creepy about his smile.

"If I think about it, a lot of people will die today."

Long Yuan tried to find even the slightest bit of unnaturalness on Xu Yue's face.

But he failed.

Not only that, Xu Yue immediately smiled and asked:

"Then, why don't you guess first, why did I come to confront you with "a soul saint and two little brats", such an obvious drag?"

The smile on Long Yuan's face disappeared.

The smile on Xu Yue's face widened.

“You can kill many people with just one thought?

"Try it.

"Show me a show."

Long Yuan's expression immediately became gloomy.

He didn't say anything for a long time.

So Xu Yue laughed out loud.

"Why is there no response? I guess you can't feel the "mediums" you use to kill people at all, right?"

She shook her head leisurely.

"I know, you definitely don't believe that all "mediums" can't sense it anymore. Then keep trying, and try farther away."

After another moment, Long Yuan's face became even more ugly.

Xu Yue knew that he had already tried it.

So she smiled and asked, "How?"

Long Yuan's face was so gloomy that he could drip water: "With so many people and such a large area, how did you cut off the connection between me and all media? It is simply impossible for humans to do it."

"Haha." Xu Yue crossed her hands, crossed her legs, and replied lightly: "Do you know the concept of "light cone"?

"The "shape" of all things in the world is revealed by light. Things are reflecting the light they receive at all times, and those light rays are reflected in the form of 299,792,450 Moving away at a speed of 18 meters per second, if you can reach 599,584,916 meters away from this thing, you can see the state of this thing two seconds ago. .

"And there is not only one light that can be reflected by an object. After infinitely extending to your observation direction, it roughly appears in the shape of a cone. You can see the object at the same moment at any point in any cone section. state. This is the light cone.

"Do you know what this means? It means that within the light cone, everything is constant and cannot be changed."

Xu Yue smiled slightly.

"Within the cone of light lies destiny."

Long Yuan frowned: "That's good, but what does this have to do with you cutting off my connection with the medium?"

Xu Yue: "Don't you realize it yet? You can only observe what happens within the light cone, but what about the things outside the light cone?"

Long Yuan's expression changed drastically.

Xu Yue smiled: "Just like if the sun suddenly goes out at this moment, it will take about eight minutes for you and me to observe the fact that the sun goes out. As long as I cut off everyone's light cone from "this moment", and then put it on you and me. No matter how elusive you are outside this light cone, it's all in vain."

This is the coronal and radiant realm.

At this point, she suddenly sighed.

"If they are not infected by your "medium", they already exist before the light cone of "this moment", belonging to the absolute past that can be observed, and I can't cut off the light cone of the past moment yet, otherwise it will only take one Planck time , you have made so many efforts in the past and infected so many people——

“Everything will turn into nothingness at this moment and become meaningless.

"Because if I can do it, it means that everything you did never happened."

The light cone theory is also a very interesting physics model. If you are interested, you can search on station b. There is an up speaker who gives a very detailed and easy-to-understand lecture~
