Zhang Yuechen jumped off the podium and spread his hands with the students of Class 8 sitting below helplessly, expressing his helplessness.

"Hahaha......" The students finally couldn't help it and burst into laughter, while Wang Chongxi brought Shen Qingliu to move two chairs to sit at the back of the classroom and listen to the lecture.

"I'm very sorry, students, it's the first time I've written a board book, and I'm not comfortable with it, so let's laugh, so we use a new teaching method for this lesson......"

Zhang Yuechen waited for the laughter to stop and explained.

Subsequently, the students in the class were in an uproar.

This time, they came from the heart, but they were really shocked!

"Is this a holographic projection?"

"No, it's not like, how can holographic projection have such a real sense of substitution?"

"And I think I can really smell the flowers......

Zhang Yuechen stood his watch on the podium, exuding a ghostly light, gradually turning the entire classroom into a paradise!

As for the so-called floral scent, it should be the result of the light brain from the assassination star stimulating their brain with a specific frequency, right?

"Okay, you! By the way, I'll call you a trick-or-treater in the future. ”

"That's, I'm an A-class light brain made by a few civilizations in the entire universe!" The little trickster's compliments on his master are very useful.

However, it still does not grasp the meaning of mischief......

The whole classroom seems to be replaced by another world, and the immersive feeling makes the students full of curiosity.

Zhang Yuechen's voice rang out: "This is the appearance of Fengchen Star when human beings were just developing civilization......

All kinds of birds and birds glided happily in the sky, the ground was lush, the mountains and rivers were beautiful, and the occasional cute animal in the jungle peeked over with its little heads peeking over.

"You can get out of your seat, here, you can smell, you touch, you hear, it's a real feeling."

Zhang Yuechen's voice sounded at the right time, and the students couldn't help but get up one after another, or get close to smell the flowers, or go into the jungle to chase the small animals......

Of course, the students who had entered the jungle had not even taken a few steps before they slammed into the window or the wall......

But even in the classroom, it is enough for these children who are overwhelmed by the college entrance examination to relax.

"The students returned to their seats."

Zhang Yuechen looked at the two teachers who were also sitting at the back of the classroom in amazement, and said loudly.

When the students reluctantly returned to their seats, the sound of the classroom was replaced by a different scene.

"This is the development of the dust star to the industrial ......"

The students looked at the original lush greenery around them and turned into endless tree stumps, and they seemed to understand in their hearts what Zhang Yuechen would talk about next......

"Brush!"

"This is what Dusty Star looks like now......"

The students couldn't see much of the wild vegetation in sight of the Dust Star......

"Brush!"

"This is the appearance of the Dust Sealing Star after it began to explore the universe and broke through to become a member of the interstellar civilization, and abandoned the Dust Sealing Star......"

The students looked at the tall buildings lined with reinforced concrete, but the breath of human beings was no longer there, and all kinds of plants tenaciously pushed through the hard pavement and grew......

"Brush!"

The scene changed again.

"This is what the Dust Sealers look like 50,000 years after abandoning the planet......"

At this time, the planet was no longer left by humans, and green and life had reoccupied the surface......

The students' mood changed from heavy to surprised, as if they were disgusted with being human and wanted the planet to return to its original state.

"Brush!"

"It's ...... The Dust Sealers have returned to their home planet......"

I saw that the lush vegetation had been preserved in a large area, and they lived in the city suspended in the air.

Only those of high status are entitled to live on the ground......

"Brush!"

"This is the Dust Sealer, after returning to the home planet, a hundred years will look like ......"

I saw that the entire dust sealing star was full of potholes, except for the loess desert, there was no other color.

"Teacher! Why is that? ”

"Yes, teacher, this shouldn't be!"

"Didn't the Dust Sealers already recognize their mistake? They've reformed and don't destroy the environment anymore! ”

"You want to know?" The corners of Zhang Yuechen's mouth curled, and he finally admitted his identity.

"Of course!"

"Yes, definitely."

Zhang Yuechen said in a deep tone: "Do you think that the people of the Dust Sealing Star want to return to their home planet? ”

"This ...... Because of the hometown plot, right? Some students replied.

"Because they're using other habitable planets badly?"

"Because ......"

The students expressed their opinions in turn.

"It's all very likely, but it's not true, and the correct answer should be this."

"Brush!"

The students appear to be in the middle of a starship, and various laser sparks can be seen exploding outside the window......

"After the Dust Sealers were promoted to an interstellar civilization, they also joined the war sequence of StarCraft."

"Of course they failed!"

The rest of them fled back to Dust, and at this point they realized that this was their last home...... So sustainability has become the theme of survival......"

"In less than a hundred years, other civilizations have followed in the footsteps of the Dust Sealers and found this ......"

"The ending is self-evident, except for a small number of people here who wander in the universe, the entire Dust Sealing Star has also been implicated and has become what it is today......"

The students were silent when they heard it, because what happened was as if they had experienced it themselves, and the sense of substitution was too strong!

Zhang Yuechen interrupted their contemplation: "Students, human greed is terrible, and when you have strength, you either bully the weak or be bullied by the strong. ”

"But there is reincarnation in the way of heaven, no matter what you think in your heart, what greed brings to mankind will be destroyed in the future......"

"So, I hope you can do your best and lead the Dust Sealing Star out of a perfect path......

Zhang Yuechen didn't know that his class today made this eighth class a "high-ranking official class" with a pivotal position in human history.

"Okay students, let's face the current reality problem - the college entrance examination, so ah, cheer me up!"

Zhang Yuechen used multimedia and watch links to reflect his own research methods and simple ideas for solving various problems in the classroom......

Since then, the learning efficiency of the eighth class of senior high school has been unprecedentedly improved......
