July 20th, early morning.

Chen Shu first visited Teacher Shi Qian, and discussed the actual use of the improved version of the thunder method with him, and had lunch. Then in the afternoon, he went to the history building to visit Professor Shi, followed them to study cultural relics from Duqin cubes for a while, and found some of their research results for free.

The two teachers obviously knew or could guess some inside story, and they were both relieved to know that he was safe.

On the 21st, the class officially started.

Ling'an Academy and Yujing Academy will start school simultaneously.

Chen Shu did not miss class. Even though the first section in the morning was "Myth Cultivation", he got up early and went to class honestly.

Because the first class has to be collected from the class leader.

Chen Shu had to go to tease the students, so that they could know that the best handsome guy in the class was finally back, and the average appearance in the class welcomed the daily limit, and by the way, they could see the great man who dared not come to class for a semester and a half.

Ning Qing naturally would not miss classes.

In fact, unless there is anything else important, or where Chen Shu wants to tell her to go or do, she will not miss class easily. What's more, the first class this semester is Mr. Euro Gong's "Diversity Universe and Planes".

She rarely misses the lessons of the old man from the euro.

"Diversity Universes and Planes" is a very important advanced course for the major of "Space and Planes", and is a junior high school student.

Ning Qing walked into the teaching building with the textbooks he received yesterday.

As soon as she stepped into the classroom, she saw the old man.

The old man was still dressed in a simple manner, like an old man sitting on a stone pier and fanning his palm-shaped fan to enjoy the cool air at any time on the roadside. He was still holding his thermos cup that he had used for many years and was blowing tea with his hair. His hair was completely white, and his face had many wrinkles. His condition was much worse than last year.

The old man seemed to notice her, turned his head and looked over, thought for a moment, and showed a kind smile:

"Class Ning Qing... isn't it? Long time no see."

"Long time no see, teacher."

Ning Qing's voice was faint, nodding to the old man, and he did not forget to explain: "I encountered some magnitude of the past, so I didn't come to school for a semester and a half. After finishing my work, I will make up for the previous course as soon as possible."

“Have you been very busy lately?”

"Um."

Ning Qing stood there with a expressionless face.

I have to learn the technique of controlling the air recently, so I can pretend to be a fairy couple outside the city with Chen Shu.

The old man nodded and said that he understood. She didn't say anything, he didn't ask, but just put down the thermos and said gently: "It's okay, just be busy, take your time, I hope we can have more communication in the future courses... and sit down."

"good."

Ning Qing found a seat to sit down.

The idea of ​​the old man in the euro has always been that academic studies are important, but everyone should have something more important than academic studies. If not, then he will not be able to help but feel regret for his classmates.

Some classmates greeted her and said something like "I haven't seen you for a long time" and they were all female classmates.

Ning Qing only responded coldly.

During the past year of study and coexistence, even though the classmates were not familiar with each other, they became familiar with each other. In addition, Ning Qing was good at studying and had outstanding appearance, so it was difficult for any classmate to have a deep impression of her. It was just that she was so cold that people dared not get close to her. After a long time, everyone guessed that she had the blood of heaven and man, and the female classmates who wanted to make friends with her stopped, while male classmates were afraid to get close to her.

Ning Qing likes this sense of distance.

"Dingling..."

The class ringtone rang.

The old man covered the lid of the thermos cup, placed it on the table, and looked up at everyone:

"Hello, you guys."

There was a messy response below.

The old man looked at the smiles on the faces of the female students and the male students stretched their necks and shouted randomly. He was very happy inside. The closer he was to death, the more beautiful he could feel the beauty of youth. Therefore, his face was inevitably infected with a smile. After a while, he said: "The content of this course is as shown in the name of the course. I will discuss with you and imagine the diverse universes and various planes..."

It gradually became quieter.

The old man tilted his head and coughed twice, then continued: "You may be able to understand the diverse planes. The diverse universes will inevitably become a little unfamiliar, right? I wonder if you have read the books I recommend to you in my freshman year? There is a book called "Cosmic Imagination: The Great Universe, the Honeycomb Universe, the Large Plane and the Small Plane, etc.", which imagines the diverse universes."

There were a response below, some said that they had finished reading, some said that they were still reading other books, and some said that they were too difficult to understand.

"It doesn't matter."

The old man still smiled and took advantage of the podium table with both hands: "It will be too late to see it again in the future.

"Everyone has learned about the previous courses. Our universe is called the Great Plane Hive Universe. Have you ever thought about a question-

“Why should we classify the universe?

"There is a large-plane honeycomb universe, and is there a small-plane honeycomb universe?

“Is there a honeycomb universe, and there are other types of universes?

"It doesn't matter if you have thought about it or not. You can think about it now and give you a few minutes."

There was a little noise below.

Some people participated in the discussion, some frowned and thought about its rationality, some people opened the book and wanted to find an answer in advance, and some people lowered their heads and ate buns and drank soy milk quietly.

Gu Sheng

Until the discussion gradually subsided.

The old man put down the water cup again and said to everyone: "The main focus of our class is on diverse planes, and diverse universes are secondary.

"Maybe one of you who has a wide range of knowledge or communication will know that among the courses in the same major of other schools, there is only the class "Diver Planes" and there is no "Diver Planes". This is because we have almost no research on the universe and there is no relevant knowledge in the books. But I stubbornly believe that if everyone focuses on the starry sky and planes, it will be very broad, but if it can be bigger, it will naturally be better. So at my request, our school added "Diver Planes" to the name of the course "Diver Planes".

"I put it in the previous few lessons, let's discuss some knowledge that is not available in books, without actual observations, and research. Maybe we can't observe it or confirm it for a lifetime, but it can broaden our horizons and thinking. Maybe one day we find a way to observe and confirm it, then you will be extremely lucky. Unfortunately, I probably can't see that day."

When the old man said the last sentence, he showed a regretful expression, and then he asked again:

"Who knows who first proposed the concept of "diverse universe"?"

"Holy Ancestor."

"Yes, Holy Ancestor."

The old man's eyes burst out, but his tone was very calm: "The Holy Ancestor proposed the concept of "various universes". He proposed in his imagination that there may be various universes in this world, similar to our universe, and different from our universe, infinite or limited, but this concept has never attracted everyone's attention... We can't even go out of the plane, so how can we view other universes?

"But facts prove that something may be illusory, but it still does not mean that it has no research value. It was in the process of trying to observe diverse universes that I found a method to observe plane barriers. This is how "Planet Theory" comes from.

"But who named the universe?

"Who says the universe is a "big plane" honeycomb universe?

“It’s the new saint.

“What is his basis?

"This is the content that is not in the book. No book in the world has recorded it." The old man paused, "You are all talented and ambitious people. I should teach you everything I can. Therefore, there is no source or basis for the next words. It is just that what I saw, heard and thought in my life, as I am over 300 years old, happened to be the first class today. There is no need to pass the class, so I will tell you to listen to you.

“Naturally, I will be responsible for it too.

"As for the use, you all decide for yourself."

It was quiet below.

Only the old man's voice echoed in the classroom:

"The New Saint is a person who opened a new era. Without him, we are still under the rule of feudal dynasties, princes and nobles, and sects. Most of you, even if you are extremely talented, may not be able to receive education, and may still be displaced, so he is a saint.

“What I can tell you is—

"The New Saint has been to other universes. He has seen the vast and boundless sea of ​​universes and different universes and rules. Later, he returned here and opened the huge screen of the times with his own strength. In the end, he disappeared again, and I don't know where to go..."

There was a silence in the classroom.

The two-hour course seemed to be only a few minutes and it ended soon. When the students walked out of the teaching building, it seemed that the sky had changed its color.

Ning Qing was a rare calm person. He just followed the crowd out of the classroom, stopped in the corridor, and looked up to watch the osmanthus.

It's early autumn again.

The osmanthus flowers bloom again.

The old man took a wooden stick and finally walked out of the classroom. He stopped a meter beside her, took a deep breath, sniffed the fragrance of osmanthus flowers, and then said to her: "The osmanthus flowers in the school this year bloomed earlier than in previous years..."

"yes."

"You are more leisurely today than before."

"No rush today." Ning Qing replied lightly, "I'm going to wait for someone I like to come to school and ask me for lunch."

"Good."

The sound of the wooden stick beside him started.

When Ning Qing turned his head, he saw the old man's back getting farther and farther away. Although he was holding a wooden stick, he still walked very quickly, as if he didn't need a wooden stick at all, and it was more like a decoration of the old man of that era. But Ning Qing knew that this wooden stick was just in case.

The decline has arisen and cannot be interrupted.

With his situation, he will last for a year.

It is rare that you have begun to decline but are still working.

Ning Qing withdrew his gaze.
To be continued...
