……

"Does the teacher believe in fate?"

"Huh?" With a look of frustration on his face, the glorious and tall image established in front of the students collapsed under Xiao Fei's merciless blow.

"Fate is predetermined, all of them are predestined, the trajectory and landing point of the floating satellite, seemingly random, may actually be predetermined. ”

"If possible, I would prefer to believe that all this is artificially influenced, not a predetermined fate. At this moment, Luo Ling seemed to have comprehended something, but when he thought about it carefully, he seemed to have not comprehended anything. Is there nothing in this world that is destined to be unchangeable?

When the bell rang for the end of class for a long time, Luo Ling sat down on the chair, distressed about the loss of his image.

"Teacher, are you not feeling well?"

"?" looked up, "It's Lille." He lowered his head again and said in a decadent tone, "It's not that you're not feeling well, it's just that you're in a bad mood." ”

"Why are you in a bad mood?" "If Lille's inquiring spirit had been put on any other time, Luo Ling would have taken the trouble to explain a little bit, but now, Lille's behavior always felt like rubbing salt on his wounds.

It's not your fault!Eh, it doesn't seem to be right, it should be your own fault, it is precisely because of your own lack of rigor that Xiaofei and Lu Sen found out the mistake, alas.

"The teacher is so frustrated because of this kind of thing? Don't you even want to talk about it anymore? Hmph, it's boring. Seeing Luo Ling's negative attitude, Hei Yu mocked mercilessly.

"Teachers don't have to be disappointed, everyone makes mistakes sometimes. What's more, you before were almost perfect for us in all aspects, and your strength was unfathomable, almost omniscient, and omniscient. We have a longing for you, but we always have a feeling of being unapproachable, and you will make mistakes, so we will feel that you are closer to us. Kazuhime spoke her inner thoughts.

"The teacher was like a child, and he would be so frustrated by the loss of face that he laughed at me. Lorsa burst out laughing, regardless of her image, and the laughter infected the others, and they burst out laughing.

"You guys......" Luo Ling looked at the smiling student, and a smile appeared on his face.

"I really shouldn't be depressed by this kind of thing, well, let's get ready for the next class. What do you want to hear?"

"Geography!" replied in unison, Luo Ling almost fell, and after a long time, he still wanted to see himself make a fool of himself, right?

Don't you want to hear about geography? I'll tell you about it. Luo Ling, who had already made an abacus in his heart, would not fall in the same place twice in a row.

In the second lesson, Luo Ling talked about the solar system from the earth, then from the solar system to the Milky Way, and finally transitioned to the entire universe itself, the students were immediately dumbfounded, and there were endless new concepts, the vast, like the abyss of the universe, the dazzling, dotted Milky Way, a huge spherical star around the huge fireball rotating day and night, Luo Ling's heart was proud and excited, and the students' hearts were shocked and collapsed. What the hell, the world is like this? Questions like this fill the minds of the students.

"Is the world really like this?" Ichihime asked everyone's problem.

"Then it depends on the category of the world you are talking about. Luo Ling replied with some malice.

"Like, do those planets, celestial bodies, nebulae, or anything really exist?" asked Lille as he stood up.

"Of course there is. ”

"However, it's hard to believe the images alone, and I wonder if what I'm seeing is real, because it's so ......," Lille continued.

"Well, I understand what you mean, maybe I'm not doing it right, and it's definitely hard for you to accept it for a while by directly exposing you to a larger world. ”

"Can the teacher let us see it with our own eyes? ”

"This, sorry, can't be done. ”

"Why?" seemed to be very interested in celestial bodies, and Xiao Fei couldn't help but ask.

"Actually, I started to work on space exploration a long time ago, but the results were not ideal. Originally, a speed of about 7.9 km/s was enough to break out of the atmosphere and enter outer space, at a speed of 11.2 km/s, it can overcome the gravitational pull of the earth and stay away from the earth permanently, and at a speed of 16.7 km/s, it can overcome the gravitational pull of the sun and leave the solar system. However, I once made a limit speed of 39.7km

/s of a small rocket, but it can't break through the atmosphere, it's a hell of a life. In order to investigate the cause, I personally reached an altitude of about 10km, endured the test of hypoxia and low temperature, and was not afraid of difficulties, coughing, and did a test, at an altitude of about 15km, there was an unknown force field, so that the resistance to the upward breakthrough increased geometrically. According to pure calculations, at an altitude of about 20 km, the drag will even exceed the gravitational pull of the black hole. This should not be possible. "I know the unscientific characteristics of this world, and it is impossible to use it.

"However, it is unlikely that you will be able to break through such a strong resistance, so don't be delusional about space travel. I speculate that the unknown force field must be a dimensional wall, otherwise it would be impossible to explain the force of the powerful Rusi. ”

Looking at the student with a blank face, Luo Ling felt that he was playing the piano to the cow again, only Xiaofei's serious expression (cute) contemplation, these things, only she could understand.

The bell rang at the end of class (Luo Ling asked Feng Rou to set it to calibrate the lessons, each class was 40min, the class started at 8:00 in the morning, the class break was 20min, the class ended at 11:40, the class started at 2:00 in the afternoon, and ended at 5:40), Luo Ling immediately announced the end of the class and began to prepare for the next class. Regarding the end of class, Luo Ling will never delay for a second, no matter where he talks, no matter what state the students are, even if the students take the initiative to ask, Luo Ling will not delay the class and occupy the time after class. In Luo Ling's words, this is a matter of principle that cannot be changed. In fact, he is so obsessed with time, and it is not because of the deep memory of being dragged by the teacher when he was in school, so he made up his mind not to delay the class (the same as the author).

In the last session of the morning, there were really no good ideas, and finally it was set as an art class, so that the students could play with it as graffiti, but as a result, Luo Ling still underestimated the creativity and imagination of the students.
