Xiang Fei glanced through the crack in the door and found that there was a black hole inside. Driven by curiosity, Xiang Fei couldn't stop himself. The door was pushed open, and it was still a black hole, black as substance. At the position of the door, Xiang Fei could clearly see a boundary, the left side was still shining in the sun of this world, but the right side was like a pool of black ink. If he hadn't tried it with his hand in it, he would have thought it was real ink.

"Come in and close the door." The bearded voice came from the darkness, with echoes, as if coming from a bottomless cave.

"Is it hell inside?" Xiang Fei asked tentatively, he was really afraid that he would never be able to go back after closing this door. This kind of speculation couldn't be more reliable: the sudden appearance of strange people, bizarre illusions, and that love that is too beautiful to be real, although Xiaoyu hasn't had time to say anything. To sum it up according to the old routine of mythology: a demon from hell has built an illusion for himself in order to seduce himself to hell, and after satisfying his wish, it is time to pull himself to hell.

"Hehe, of course not, but you can go to hell here, if you want, you can go and see it." The voice seemed to laugh a little, and said casually, "Come in, maybe it's a fairyland." ”

Curiosity! One of the functions of curiosity is to heat the brain. Xiang Fei just relied on the instant heat of his brain and walked in. However, he did not close the door, ready to run away at any moment.

"Close the door." The man didn't intend to leave him a way out. And that voice seemed convincing.

Xiang Fei pushed the door behind him. When the last light disappeared, the room suddenly lit up, and Xiang Fei was pierced by the strong light and closed his eyes, but when he opened his eyes gently, he didn't feel the light dazzling. After seeing the scene in front of him, Xiang Fei was shocked again.

The scene in front of him was all too familiar to him, it turned out to be the high school classroom he had been in for three years, and he had just entered the door and had not moved a single step. But he was standing in the same position as he was in the first row of the classroom. Looking back, the door behind him was gone, replaced by neat rows of desks.

"Sit down." The bearded voice appeared abruptly.

Turning back, the bearded man was standing on the podium. By this time, his thick hair and beard were gone, and he had been replaced with a lean flat head. Xiang Fei only recognized him by his voice.

"Sit." Pingtou stretched out his hand and motioned for Xiang Fei to sit down, and Xiang Fei sat down so calmly.

The two of them looked at each other with big eyes and small eyes, and it took about a minute for them to flat-head and say, "You're not curious?" ”

Xiang Feimu nodded.

"Then you don't want to ask something?"

Xiang Fei still nodded.

Pingtouer could only pat his head helplessly and said: "Since that's the case, just listen to me, and if you don't understand, just interrupt me at any time." After a pause, he added, "But I can't necessarily give you an answer either." ”

Xiang Fei still nodded blankly.

"Alright! Listen well. The class bell rang very cooperatively outside the classroom.

Pingtou drew five circles set together on the blackboard, which were not very regular, but it could be seen that he wanted to draw five concentric circles, and then he painted the middle circle white with chalk and asked, "What is this?" ”

This time, Pingtou was not fooled by Xiang Feimune's nod. A pair of eyes just looked at Xiang Fei like that, as if he had to give an answer before it was finished.

"Uh...... Earth? Xiang Fei finally held back a whole sentence.

Pingtou nodded, but still stared at him.

"Atoms?"

Flat head nodded, but still stared at Xiang Fei.

"The solar system, the Milky Way, the universe? Cell? Or is it a target? Xiang Fei gave many answers in a row, and the sense of restraint disappeared a lot.

"Hehe, both. From the atom to the universe, they all have similar models. What I'm trying to say is that if you extend this to spacetime, the model will still work. Then Pingtou told him a set of theories that seemed far-fetched.

"Our world is made up of matter and energy, but all matter can be annihilated into photons. So our world can also be said to be made up of only energy. Energy is not only the origin of our world, but also the origin of the entire time and space.

Space-time, like the atoms, the Earth, the solar system, and the universe, has a core and several energy planes. The space in which our universe is located. Extending to our universe, it is material, wrapped in layers of energy universe on the outside. The energy universe is made up of energy and fields. The energy is repeated in a field that is stimulated by itself. And this cycle strengthens the field.

Our universe comes from the Big Bang, and the Big Bang happened because the energy in a low-level energy universe began to become complex, and there was interference between various fields, so that the energy changed from order to disorder. The density of disordered energy decreases, and in order to continue to maintain the energy movement, a carrier of matter is formed......"

When he finished talking about the space-time model, Xiang Fei almost fell asleep. Although he has the label of "good student", Xiang Fei is a person who does not like to listen to lectures, and he prefers to study on his own. If there is any benefit to him in the teacher's lectures, it is hypnosis.

But the words behind the flat head made Xiang Fei sober up with a spirit.

"This dark room is the singularity from the Big Bang, which can switch freely between the two states of energy and matter. The illusion you construct today uses its energy as well. ”

When mentioning the black room, Xiang Fei suddenly came to his senses: "Have we crossed over?" Is that illusion what the energy universe looks like? ”

The bearded man who turned into a small flat head smiled bitterly and patted his head: "It's not that you entered the energy universe, but the energy of the energy universe constructs the matter of the three-dimensional space. ”

"Matter? Are the flowers and trees and the meteors real? Xiang Fei finally had the consciousness of being a student and began to ask questions constantly.

"Of course it's true, if you hadn't stopped, those meteorites might have really knocked the earth into a few big holes." Pingtou said it easily and calmly, and he didn't know if it was true or not.

"Then I can be on the news network, right?"

"Hehe, the beauty of thought. The universe you see is something you have built, but no one outside of this energy can see anything. Of course, waiting for those meteorites to actually hit the earth is another matter. ”

"Can I manipulate energy? Am I the prince abandoned by the energy universe? Xiang Fei thought beautifully, and the corners of his mouth couldn't help but curl.

Pingtou coughed lightly to wake Xiang Fei up from his fantasy and said, "You think too much." It is the black stone in your chest that controls the energy. Or more accurately, it's the black stone that communicates you with the black house. You're just coming up with a blueprint. The energy in the black stone is a conscious energy, like the life form of our dimension. Because of the similarity, it can communicate with the human brain. I'll tell you about this later, and your task today is to figure out the structure for me. In short, you communicated with Blackstone, and Blackstone communicated with Xiaoyu's brain. "Flathead dotted the ugly circles on the blackboard with chalk.

Xiang Fei was still confused when he heard it before, and he was a little excited after hearing it. This is nothing short of a myth.

"So what I just saw is an illusion that my brain has been controlled?" Xiang Fei asked, and his mind was already thinking about how to surprise Liu Xiaoyu for the second time.

"That would have the same effect, but you're an exception this time. This time, I made an exception and used the energy of the Black Room to create a substance-like existence for you. The free conversion of energy between the real and the unreal is the biggest feature of the Black House. What do you think? How much did you understand? ”

"I guess I understood." Xiang Fei hesitated

"Okay, class." After the class ended, the bell rang out at the right time.

Originally, his mind was still full of clarity, but when Xiang Fei walked out of the dark room and looked back to see the weeds behind him as always, his head was dizzy again.

When he got home, Xiang Fei rushed into the bathroom and washed his face with cold water. After washing for a long time, he felt that the water was not cool enough, so Xiang Fei took ice cubes from the refrigerator and soaked them in a basin of ice water before washing. The aunt in charge of cleaning saw Xiang Fei's nonsense, and finally couldn't help asking, "Xiaofei, what's wrong with you?" His hand was still touching his forehead as he spoke.

"It seems to be a little hot." Auntie was talking to herself while touching it.

"I'm not sick." After a perfunctory sentence, Xiang Fei lay back on his bed.

His thighs had been numb by his own pinching, but it still hurt as always. He kept his eyes open and thought about the day. When I open my eyes, I am afraid that I will not be able to distinguish between dreams and reality when I close my eyes. When the reality of the memories was gradually swallowed up by the night, and Xiang Fei gradually believed that it was a dream, the sudden ringing of the mobile phone scared Xiang Fei into a thrill and almost rolled off the bed.

casually swiped the mobile phone and said "Hey", and a sweet voice immediately came from the microphone: "Hey, how did you get it?" Or did I have a dream? ”

The voice was light rain, but Xiang Fei had never heard it. The voice was lively like a string of bouncing rabbits, frightened and a little excited.

"Huh? Yes! That ......"

"It's really beautiful, I told my mom. She actually said I was dreaming. I asked Xiao Ran, and she also remembered the afternoon. Otherwise, I would have thought I was dreaming. Xiaoyu actually cried again like a little neurotic.

"It's true. If you like it, don't tell anyone. This is definitely not perfunctory, the voice on the phone is too real, and the sweet and greasy feeling is too real, Xiang Fei finally affirmed his experience during the day. Not for anything else, just because that thing was no longer something he needed to think about. He's in love! This is the problem that Xiang Fei needs to spend time trying to distinguish the real from the fake.

"Is this a relationship? Not counted? Calculate? Xiang Fei kept breaking the petals of a rose in his head, but the flower was always wrapped in thick petals, and it seemed that it could never be torn off.

Xiang Fei's abnormality frightened his roommates.

When I went home in the afternoon, my face was blank, and I was always in a state of distraction. After dinner, his face was still full of blank and regular distractions, but he added a smirk without warning. The classmate was frightened and told the dean. The dean brought Dr. Liu from the infirmary.

"Are you alright?" The old dean asked cautiously.

Xiang Fei was stunned for a moment, and only when he saw the dean did he reply normally: "I'm fine." ”

The dean glanced at Dr. Liu hesitantly, but the other party did not react. The dean then tried again: "Have you decided to go to Tsinghua University or Peking University?" ”

"Huh? I'm going to Yale! ”

Hearing Xiang Fei's answer, Dean Xiang couldn't help but feel a chill in his heart: "It's over, there must be something wrong with Xiang Fei's brain!" ”

It wasn't until the next morning that the old dean himself appeared again with a big beard. She asked Xiang Fei a question as if she was relieved: "Are you sure you want to go with Mr. Tang?" ”

"Hmm. Are you sure. Xiang Fei nodded affirmatively.
