Since Yan Xin moved to Mars, he feels that all his troubles have been swept away, and he feels a lot more comfortable without the intrigue on the earth, and he does not have to be afraid to protect his world.

Although Luo Tianyi and Yanhe agreed to Yan Xin's request, they were still reluctant to live on the earth, and Yan Xin also discovered this situation, seeing their depressed mood every day, and finally agreed to let them live on the earth, but to change their identity, they can't let people know their original identity.

Luo Tianyi and Yanhe quickly prepared to return to the earth, and when they saw their appearance, Yan Xin was speechless for a while, but fortunately, he had to do something meaningful in his long life, and he had to start a new journey.

Yan Xin's heart is ready, the road to find the truth is full of thorns and bumps, and especially involving many planes, the earth has begun a plane war, and in this period, he can be said to be an identity in a blank period, and there will be no risk of exposure to any plane.

This is a means of self-preservation of the world consciousness, and it is also a tacit custom, in order not to be discovered by the will of other worlds in the event of war.

After sending away Luo Tianyi and Yanhe, Yan Xin also began to prepare to find the plane, not using the plane coordinate positioning program, but relying on Yan Xin's own ability to find it, because the plane coordinate positioning program has a drawback, and the discovered world is completely based on the principle of proximity, and the plane level is not high.

Yan Xin gave up after using it a few times, except for the Demon Forbidden World, the other worlds have no use value for Yan Xin at all, but the dimensional coordinates of these worlds Yan Xin still threw it to Gaia, after all, for civilization, those are resources.

Mixed with the whistling unknown object rushed quickly towards the person lying on the desk, the surroundings were quiet, and the atmosphere seemed to be a little depressing, Yan Xin's body instinctively grabbed the object that rushed towards him.

The instinctive tightness of the body, a vague evil aura emanated from Yan Xin's body, and just when Yan Xin was about to subconsciously look for the target, he found that this object was a blackboard sassafras.

Immediately Yan Xin came back to his senses, his eyes scanned for a week, looking at unfamiliar faces and familiar environments, isn't this a high school classroom. Yan Xin hurriedly restored the harmless appearance of humans and animals, but it was too late, although Yan Xin had been precipitated by peace on the earth for several years, the evil spirit was much less but more solid.

The students around him were all terrified, even the teacher on the podium looked at him with an extremely frightened look, his legs kept shaking, and he was almost unsteady, but his feet were like deep roots and he couldn't move.

Yan Xin was a little embarrassed when he saw this situation, but he quickly recovered.

"I'm sorry, I was so tired yesterday that I fell asleep in your class today, and I won't be next time."

Suddenly, the students and teachers felt that Yan Xin's words soothed their hearts like a spring breeze and calmed their fears.

The teacher quickly recovered, looking at Yan Xin with a strange look, the momentum displayed by Yan Xin just now, she will never forget it for the rest of her life, the sense of fear that penetrates deep into the soul, and the powerlessness of encountering natural enemies, makes her jealous, and the words she originally wanted to curse were instantly stopped, for fear of annoying him again.

"Okay, then you sit down first, rest early next time, and don't sleep in class. Let's move on to the lecture. ”

。

The teacher went down the new step, and there was a kind of diversion of his attention by the way.

"Oh, good."

Yan Xin sat down generously without a trace of embarrassment.

The time of a class passed quickly, and the performance of Yan Xin in the class just now instantly aroused the onlookers of the students.

"Brother, how did you do it. That old witch has a bad temper today, I thought you were dead, but I didn't expect her to let you go without any fart. ”

"Yes, the moment you catch the blackboard, I feel like you're not you anymore, as if you're going to kill us together."

"How is that possible, you are delusional, this is a society governed by the rule of law, killing people is a crime, I don't want to go to prison, I am still young, and I have a lot of time to do what I want to do. It would be a shame to waste my time in prison, and most of all I didn't want to pick up soap. "Yan Xin's avoidance of this topic.

"Did you notice that the old witch was speaking in a much softer tone afterwards, which had never been done before. I hope it's good to do this every day in the future, eh, why don't you scare her again? ”

Listening to this bad idea, Yan Xin was speechless for a moment, these are the cannibal flowers of the country, if you want the teacher to be gentle, at least don't let the teacher worry, the teacher will naturally get better if he doesn't have so many troubles, and the students and teachers influence each other.

"Go yourself, I wish you the best of luck." Yan Xin refused.

The classmate who had a bad idea wanted to continue, Yan Xin glared at him directly, didn't speak for a moment, and stood there at a loss, just now he felt that his own life was targeted by an unknown existence that exuded this terrifying aura, and the fear engraved into his soul made him feel a deep sense of powerlessness.

It took a while for this feeling to pass, and a sense of happiness for the rest of my life after the catastrophe came to my heart, and my body reacted, my limbs were weak, my breath was short, and cold sweat appeared on my forehead.

"You're all right." Yan Xin asked with concern.

Looking at Yan Xin's shush and asking for warmth, the classmate's body instinctively stepped back, shook his hands straight, and said incoherently.

"I'm fine, I'm fine. Thank you for your concern. ”

"That's good, it's almost class. Let's go and prepare the books for the next lesson. Yan Xin dispersed the classmates who were surrounding him.

"The water in this world is a bit deep, and there is even parallel space."

Yan Xin pretended to be serious about class, and secretly analyzed the world.

Now that Yan Xin has a basic understanding of this world, the thing that makes Yan Xin feel strange is that there are seven parallel spaces in this universe, and they usually do not interfere with each other.

However, every 100,000 years, these seven parallel worlds have seven days of overlapping time, and in order to maintain the balance between civilizations, this universe will not let any civilization perish, so that these civilizations will continue to repeat history, and there will never be any possibility of unification.

In order to prevent the civilizations of the parallel universe from interfering with each other, the memories of the people involved will also be deleted, even if they are lucky enough to remember the repeated things in the universe, but no one will believe them when they say it, and they can't make any waves at all.

Is this world hiding, the seven civilizations are unified, and the will of the world is the strongest, and it is not impossible to be promoted to a high-level civilization at that time, but why should this universe be hidden, is it targeted by the consciousness of the rules of the plane, or has it become their subordinate.

Yan Xin feels that this world is a little weird, no world will can resist the temptation of promotion, especially the improvement of self-civilization, which is more beneficial to the world will, and there are basically no sequelae.

This world is holding back, and would rather let the seven parallel universes repeat and repeat than be promoted, there must be something strange in this. Well, interesting.

Yan Xin found that there are some interesting characters in this school, they are like three bright fireflies in the dark night.

And on the periphery of this planet, there are two forces that lock this middle school, to be precise, lock the two fireflies, one force comes with a malice, without the slightest intention to hide it, and the other force Although it is well hidden with the power of time and space, it still can't escape the perception of Yanxin, and that force has a sense of destiny in God, which should be to maintain the balance of the seven universes.

"Report to the sir, find a weak signal from the target."

Inside a spaceship, a group of people were constantly scanning the Earth, and when they had the location of the target, they hurriedly reported.

"Where."

After locking the signal, the original projection of the earth continued to zoom in, and finally locked the address to a young girl in front of a high school.

The girl seemed to be aware of it, and quickly clicked on her wrist a few times, and the original signal disappeared instantly, but it was too late, her coordinates had been exposed, and the girl didn't seem to be aware of the fact that she had been exposed, as if she was very confident in her hiding.

Seeing the target appear, the captain suppressed his excitement and made a fate.

"Lock on to the target."

"Yes."

The hideous-looking spaceship in space immediately headed for Earth, and all this was under the watchful eye of one person, ready to say that it was not human.

Carrying a turtle shell on his back, he looks a little old and seems to have experienced a lot of things, and there is this great wisdom and a kind of benevolence for all things in the world in his cloudy eyes. Looking at the spaceship heading for the earth, I couldn't help but sigh.

It's been 100,000 years, and it's finally here.

In physics class, the physics teacher wrote the four big characters of parallel universes on the blackboard, preparing to talk about the theory of parallel universes.

The Mediterranean of the Mediterranean of science seems to be present in all kinds of science teachers, and the physics teacher is ready to start today's lesson. Ladies and gentlemen, do you know what a parallel universe is, this is a very interesting topic.

To understand what a parallel universe is, we must first understand Einstein's general theory of relativity.

The physics teacher smiled awkwardly at the following reflection, physics is indeed a bit boring for them, and this reaction is also expected by him, the class still has to continue, but there is a student who snores too blatantly and does not put himself as a teacher in his eyes at all.

The physics teacher's face changed instantly, and the students below also followed the sound to the last row to see which talent it was. The tablemate seemed to notice this phenomenon, but no matter how much he screamed, he couldn't wake up, and the physics teacher couldn't bear it.

Fire Linfei!

The voice that resounded through the classroom sounded, and Huolin Feilei couldn't move and turned over to continue to meet Zhou Gong.

Fire Linfei!

The physics teacher's voice was louder than before, and anyone with a discerning eye could see that the teacher was already on the verge of doing it.

Huo Lin Fei didn't move, and a small snoring sound reached the ears of everyone in the classroom, which was an invisible mockery of the physics teacher.

The physics teacher couldn't bear to grab something and throw it over, since language can't wake up, then he can only rely on physical means. At this time, Huo Linfei finally woke up, but his body was forced to wake up when he was in danger.

Huo Linfei seemed to be accustomed to this situation, and took the initiative to stand up and say. Actually, my name doesn't have to be so big.

The physics teacher began to find fault.

"Huo Linfei, let me ask you, what is a parallel universe."

This stopped him, after all, a high school student has not learned how to learn about parallel universes.

Looking at Huo Linfei, who kept scratching his head and couldn't answer, the physics teacher felt a little revenge, and he could finally use the question to play, and he couldn't catch any tricks, after all, if he didn't listen carefully in class, it was reasonable for him to punish him.

"If you can't answer, don't rush to leave after school, when you figure it out and when to leave."

This is equivalent to taking Huo Linfei's life, as a student who doesn't want to escape from the school, but he can't answer the things of the parallel universe at all, but he keeps delaying time in order to go home early.

The girl who originally appeared at the school gate appeared at the door of Huo Linfei's classroom at this time, and there seemed to be a sense between them, seeing Huo Linfei's overwhelmed appearance, they couldn't help but help him.

Huo Linfei instantly felt that his brain was extremely clear about this question, as if he had grasped the backbone.

"According to Einstein's theory of general relativity, there are other universes parallel to us outside of the universe in which we exist, and these universes are strikingly similar.

For example, in another universe, there may be a person who looks exactly like us, but unfortunately, we can't usually travel through these parallel universes unless we can pass through wormholes.

However, according to the general theory of relativity, these wormholes have a very strong gravitational pull that can destroy all foreign matter, so it is almost impossible to travel through the wormholes in time and space. ”

The physics teacher was dumbfounded, and looked at Huo Linfei in surprise, originally just wanted him to understand not to sleep in class, but his words really surprised him, and it was a kind of personal witness to confirm it.

"How do you know these things, you know, these things haven't been confirmed until now."

Seeing that Huo Linfei had solved the predicament, the girl withdrew her help, and at this time, Huo Linfei was a little inexplicable about her reaction just now.

"yes, how do I know that! Could it be a dream! ”

The physics teacher looked at the confused Huo Linfei and said helplessly.

"Okay, you sit down first, and you're definitely not allowed to sleep in class in the future, you know."

"Yes, Teacher." Huo Linfei replied loudly, and the matter of sleeping by himself passed inexplicably.

The physics teacher wasted a lot of time on Huolin Fei and hurried back to class.

"Now let's start with Newton's first law...

Huo Linfei's tablemate saw that he had a perfect fit, and gave a thumbs up in admiration, Huo Linfei looked at his tablemate with some pride, and saw a girl in the window out of the corner of his eye, and there was a feeling in the dark.

"Slender Jun, who is she."

Slender Jun also noticed the girl following Huo Linfei's gaze, and he was a little distracted for a moment, and said.

"I don't know, it might be the new girl in the next class."

The physics teacher looked at Huo Linfei and shouted in his ear.

"Listen carefully."
