My granddaughter gave me a mecha for her birthday, and the scientific community went crazy

Xu Fan returned to the podium and looked at Yan Youchu.

After Yan Youchu hesitated for a moment, he said softly without rushing into the question just now,

"Teacher, I'm done asking, thank you!"

"Please sit down!"

Tang Shiyun's two white and tender little arms were propped up on the desk, and her chin rested on her hands.

Blinking her long eyelashes, she looked at Xu Fan quietly in the crowd.

Exhale gently through your small mouth.

It was like he breathed a sigh of relief, but also felt a little bit regretful.

I don't know what's going on.

Xu Fan said loudly to the students in the classroom,

"Understanding the mysteries of plants requires us to fundamentally understand their growth and evolution."

After finishing speaking, he raised his hand and quickly wrote 'Growth and Evolution of Plants' on the blackboard! 'Eight big characters.

The font is majestic and the iron paintings and silver hooks give it a bit of a calligrapher's charm.

Then lay the phone flat on the table.

With a slight movement of your palm, a 3D virtual control interface is projected out.

With two quick clicks of his dexterous fingers, the projection of a green plant appeared in the student's eyes.

"Look, everyone, this is a relatively common plant, Artemisia annua!"

"..."

In the following time, Xu Fan used 3D projection to analyze the birth, growth and aging of plants from shallow to deep.

It also explains from the emergence, reproduction and decline of plants.

The students slowly transitioned from liking the person on the podium to a desire for knowledge.

The look he looked at Xu Fan was full of heartfelt reverence and kindness.

Everyone's relationship is gradually getting closer.

It's like an old master passing on the mantle to his apprentices.

Even the rhyme of Tang poetry was mesmerizing.

Listening to Xu Fan's lectures is a kind of spiritual baptism.

Be able to recognize the essential operating laws of this world, be aware of the vastness of all things, and be able to see your own insignificance!

It's like someone holding your hand, taking you to 10,000 years in prehistory, and picking a piece of grass from that period with your own hands.

Then go back thousands of years and pick a grass seed.

Finally, I return to modern times, sow grass seeds into flower pots, watch the grass sprout, grow vigorously, bear flowers, and finally wither and decay, completing a lifetime.

It was Xu Fan's first time teaching in a classroom, and he was a little uncomfortable at first. Gradually, he discovered that these children were very cute and had a strong thirst for knowledge.

A hearty class gradually came to an end.

Xu Fan was still telling the story seriously.

"The reason why life is magical is that there are countless possibilities."

“Plants are the building blocks of life’s expanding populations.”

"It is the patron saint of creating and maintaining the ecosystem."

At this time, someone in the classroom suddenly raised his hand.

This time it was not Yan Youchu, but the shy young lady in the corner.

The students in the class all looked stunned.

From the moment this young lady entered the classroom, she basically said nothing and listened carefully to the class.

Now I even started to ask bold questions.

Everyone was curious what she would ask.

Xu Fan gestured to please speak.

Under the gaze of everyone, Tang Shiyun said seriously,

"Teacher, if you want to transform a place with extremely harsh living environment into a place suitable for animals and even humans, how can you do it?"

When Xu Fan heard Tang Shiyun's question, he thought that she was indeed a talented woman with four doctorate degrees. The questions she asked were all so hardcore!

But Xu Fan didn't even have to think about this issue.

Because he has solved it.

"If you want to do what you said, just take three steps! First, you need to establish basic life support devices, then cultivate super plants with strong vitality, improve the soil and air, etc., and finally use the improved plants for planting!"

"Thank you...Teacher Xu!"

Tang Shiyun said and secretly glanced at Xu Fan.

Xu Fan smiled and said, "Please sit down!"

I looked at the time, class was about to end.

He said to the students,

"We will stay here for this class. I will still teach here for the next class. You should also be listening to the class, right?"

“I’ll show you how to do it in the next class!”

“Only by combining theory and practice can you learn profoundly!”

"Thank you for listening carefully. See you in the next class!"

"bell--"

As the bell rang, Xu Fan tucked the textbooks and lesson plans given by Mr. Tian under his arm and walked out of the classroom.

Tang Shiyun in the back row also quietly opened the door and left.

The two quickly disappeared down the corridor.

In the classroom, countless people jumped up from their chairs as they heard Teacher Xu walking away.

Excited shouts.

"Great, the next class will be Brother Xu's class!"

"Brother Xu said he would take us to practice, where do you think we would go?"

"Hey, I guess it's the school's crop growing area. I've been there dozens of times."

"Brother Xu is not married yet, I want to have a heart-breaking sadomasochistic love affair with Brother Xu!"

"You can pull him down. I think Brother Xu likes You Chu very much. You will definitely have no chance!"

"Really? Brother Xu likes me very much? Tell me quickly, is it true? Tell me quickly!!"

"No way? There's no chance for me? Doesn't Brother Xu like a strong person like me, and a weak person like You Chu who can't take care of himself? How can this be done! If you take one step and calm down, if you take a step back, the more you think about it, the more angry you will be. I don't accept it!"

Discussions broke out one after another, and the whole classroom was in turmoil.

Not long after, the front and back doors of the classroom suddenly opened.

All kinds of people of the same age, senior and junior grades came in.

There were people in the crowd shouting.

"Classmate, I will pay you 100 yuan to buy the seat you occupy now!"

"How dare you give me 100? I'll give you a thousand!"

"Tch, if anyone gives me the seat he occupies, I will give him my latest Pura 70 Ultra! I only used it for two days!!"

"Are you serious? If anyone is willing to give me a seat, I, I, I... I will give myself to him!"

"Go away! What the hell are you calling a man here!"

"It made me excited. I will really thank you!"

After the class just now, the value of the seats in this classroom has increased.

Superstar concert tickets are incomparable to this.

Gradually, smart little guys began to sneak in with their own stools, and even more people began to fight for seats.

The classroom that originally accommodated a hundred people was filled with more than 500 people.

There are still people trying their best to squeeze in.

The classroom began to lack oxygen, and it seemed that I couldn't breathe.
