The class continued, and in the quiet classroom, the students listened attentively, and no one made any noise to disturb the teacher.

Jiang Yiyun smiled lightly, the confident look in her eyes seemed to be overflowing, the sunlight shone through the window glass, covering her beautiful face with a layer of hazy light, it looked a little unusual, the skin on her slender neck was pink, as if there was brilliance flowing inside, like an orchid blooming in the sun.

The male voices were all stupid, and the girls were also impressed by Jiang Yiyun's elegant and calm posture, and they were all engrossed.

Du Xiaofeng looked at Chen Yuan with a strange expression, a tear, an inexplicable smile slowly appeared on his face, his eyes were deep and distant, as if he was staring at his sweetheart, and it seemed that he suddenly had an epiphany and made a major decision......

Anyway, how did Du Xiaofeng think that Chen Yuan was so abnormal, it was the same as a neuropathy.

Of course, if you put it in a more literary way, you are an idiot.

"So that's the case, no wonder Chen Yuan doesn't want to see the school flower, it turns out that this guy really likes mature women. And when I saw my sweetheart crying, I was also an infatuated lover with deep affection! Alas, unfortunately, you are destined to have no part in this life. ”

Du Xiaofeng thought like this, his eyes seemed to be able to transcend time, and he had already seen his brother's death or death for the sake of the beautiful teacher, and his heart couldn't help but be full of pity. I still think about it, when I have lunch at noon, I will talk to him alone, of course I can't be in a hurry, and I will slowly persuade him to do this kind of thing.

At this time, Chen Yuan had already recovered, and after Fang Cai's reminiscences, his spirit was much more proficient, and his spiritual sense had become clearer than ever, and his gaze at Jiang Yiyun no longer had the slightest affection. Even if the person in front of him looks like Xueyi, he is not after all.

Chen Yuan leaned back, flipped through the notebook casually, and then began to draw on it.

Time has passed, and the PPT on the screen has been turned to the last page.

Evaian stopped her rambling retrospective, and then concluded:

"Personally, I have always believed that in our country of China, it is not accurate to define the period of Great Nirvana as the five years from 1962 to 1967. The Sino-Japanese War was the beginning of the Nirvana of China's tragic song, followed by the 918 Incident and the 77 Lugou Bridge Incident...... The Nanjing Massacre, the Lushun Massacre, the ZQ Bombing...... It was not until the victory of the War of Resistance Against Japanese Aggression that China attained nirvana on the spiritual and cultural level, which laid the foundation of the Chinese People's Republic......"

“...... After that, the 'YX virus' broke out, and we were in danger of extinction. The final result was the establishment of the 'Coalition Government of Mankind', which further promoted the accelerated integration of various countries and nations around the world, which is the true meaning of "Great Nirvana", rather than simply the appearance of monsters and warriors. ”

Therefore, in this regard, some scholars in our country prefer to call the "Great Nirvana Period" the "Fourth Great National Integration Period" in China, and this process of integration has continued to this day. Therefore, it can be said that the "period of great nirvana" of our Chinese nation is still going on until now. ”

Jiang Yiyun clicked on the notebook, and pictures immediately appeared on the projection screen, including warships confronting each other, virus DNA spirals, huge monsters, and warriors whose names could be called out in textbooks.

Some students in the classroom are short of breath, everyone is familiar with the history of this "Great Nirvana", although it is only four years, but there are too many film and television dramas, animations and books that have depicted the heroic stories that happened in this history.

"Which student got up and gave us a brief account of the events of the Great Nirvana period?"

Jiang Yiyun raised her head again, and her soft smile shone brightly. As soon as the words fell, almost all the male classmates below raised their hands in unison, after all, in front of their goddesses, boys still prefer to show themselves, especially this kind of good time to show their erudition in public.

Among the girls, only those who are scholars or who really like history raise their hands, including Chen Xiaohua, the god of learning, but the beautiful teacher has no intention of choosing her, because she knows that this little girl has very good grades, and she can't find any knowledge points, and she can't find any mistakes, so she can't have the effect of teaching.

She glanced around the classroom, and finally her eyes fell on Chen Yuan, and she couldn't help but feel angry in her heart. Other classmates are listening carefully, and you are doing other things with your head bowed alone.

Want to get my attention in a unique way?

What a childish boy. Well, in that case, then I've fulfilled you.

Frowning slightly, Jiang Yiyun smiled: "Classmate Chen Yuan, please narrate it for all of us." ”

Hearing this voice, all the students put down their hands in great frustration, and at the same time they were a little surprised, how did Mr. Jiang choose Chen Yuan, a marginal figure today, what can he know, a guy who has failed for many years in history?

Many of the students showed a look of watching a good show.

Chen Yao put down his hand stupidly, glanced back at Chen Yuan, a smile appeared on his face, and he was a little gloating. But she had already made up her mind in her heart, if the old brother really couldn't say one, two, three, she would immediately stand up and help him out...... But I don't think so, they only reviewed this history together a few days ago.

Zhang Tianming, a wealthy man, showed deep jealousy in his eyes, and he was very unhappy that the beautiful teacher turned over that waste brand.

And Du Xiaofeng, Xue Guo, and Li Weiguo, who saw everything in their eyes, were dumbfounded.

Damn, we're ...... Have you been deceived?

This guy was pretending just now! A wave of commotion has successfully attracted the attention of a beautiful teacher.

pretended to be deep again, pretended to be melancholy, and shed tears...... This bastard.

I've known each other for three years, but I didn't expect you to be such a baby dragon!

Chen Yuan naturally didn't know the mental activities of the classmates around him, he raised his head when he heard the words, and then stood up, and while closing the notebook casually, he had already seen the expressions of the nearby classmates.

He looked at Chen Yao and asked with a smile: "Classmate Chen Yao, I don't know much about history, why don't you help me?"

Everyone was stunned, they didn't expect Chen Yuan to have the courage to take the initiative to talk to the school flower! Chen Yao turned his head and smiled and encouraged: "No, classmate Chen Yuan, Teacher Jiang is testing you, don't be shy and boldly say, if you are wrong, we will all correct you on the side." ”

After speaking, she also made a cheering gesture with her pink fist.

Joke, how is it possible to let Miss Ben help you? Do you think that Miss Ben's anger will disappear just now?

This bastard, he actually made a small report to his mother, and he didn't accept it just now, and now I see how embarrassed you are? Oh, hehehe......

Chen Yuan touched his chin, and looked at Zhang Tianming again, this little gangster laughed the loudest just now: "Classmate Tianming, if you don't come, how about I let you be in the limelight?"

Zhang Tianming was unhappy in his heart, you are purely disgusting, I took it, does it mean that I am a showy person, such a mentally retarded scheme, I will not be fooled...... It wasn't me who Evian took the initiative to call.

He waved his hand and said with a smile: "No need, Chen Yuan's historical level is much higher than mine, so you should come." ”

"Well, it's a lot higher, indeed. ”

Chen Yuan nodded, no longer looked at Zhang Tianming's face as if he had eaten stool, his expression was slightly solemn, and his eyes said calmly:

As we all know, the period from October 28, 1962 to September 9, 1967 is known as the "Great Nirvana Period" of our human race, which is an extremely important and glorious history, and is also known as the "Nirvana War" or "Cataclysmic War". It can be said that at that time, the survival of mankind was in an instant......"

"At the end of the fifties of the 20th century, the United States and the Soviet Union competed for hegemony. In 1959, the United States deployed intermediate-range ballistic missiles in Italy and Turkey, and Soviet Russia deployed missiles in Cuba in order to recover its strategic disadvantage......"

"On October 15, 1962, the United States and the Soviet Union had a fierce confrontation in the Caribbean that shocked the world. On October 28, after 13 days of standoff, the two aircraft carrier formations fired missiles at each other...... The Third World War has broken out!"

"The war began to be extremely intense, and as the fighting deteriorated further, both sides invariably used nuclear weapons on November 4. As of November 13 of the same year, the United States and the Soviet Union had dropped a total of 79 nuclear warheads in and around the Caribbean......"

"There is no winner in a nuclear war. At a time when the situation was further expanding, China spoke out for the first time and warned the Soviet and American governments to strive to exercise restraint. He immediately intervened with many powerful countries and many developing countries in the world, actively mediated between the United States and the Soviet Union, and did a lot of work, and finally reached an armistice agreement on January 7, 1963, and the crisis of human extinction was resolved. ”

"Although the Third World War did not last long, according to the statistics after the fact, the death toll of this nuclear war was as high as 200 million, four times that of the Second World War, and the specific number of casualties cannot be counted. And the problem of nuclear radiation contamination after the incident has spread to this day......"
