Li Deren picked up a notebook, on which was Professor Wang's daily diary, a few pages of which were about the diary of the ten days he entered Bianshan.

Ning Bei personally flipped through it, ten lines at a glance, and when he flipped it back, only the last three pages were missing!

Professor Wang entered Bianshan on July 1, 2010.

But only the records of the first seven days were torn up in the last three years.

Ning Bei looked at the tear marks, which were already yellowed, and they were not torn off recently.

Li Deren asked tentatively: "Professor Ning, these three lost pages are not in the way, right?" ”

"Someone tore away the last three pages and recorded Professor Wang's traces in Bianshan in the last three days, but according to the clues on the first seven pages, the search can also be narrowed!"

Ning Bei put away his notebook.

Li Deren was a little embarrassed to speak, obviously asking Ningbei.

Ning Bei chuckled: "I don't like to owe favors, you sent the notebook, there are conditions, right?" ”

"I can't talk about the conditions, I just want to ask Professor Ning to go to my research room when he has free time!" Li Deren was a little nervous.

Ning Bei glanced at the class schedule, there was a class in the morning, and Li Deren could only arrange it in the afternoon.

Li Deren immediately prepared in the scientific research room, happy like an old child.

Sun Zheng said helplessly: "This old thing has been thrown into gravity research for half of his life, and has always intended to use the earth's gravity for industrialization and replace oil and other energy sources!" ”

"Alternative energy is a false proposition!" Ning Bei mentioned indifferently.

Anti-gravity research is generally used on aircraft, and the installation of anti-gravity components in aircraft can greatly reduce the take-off and landing time of aircraft!

As we all know, the most dangerous part of the aircraft is the take-off and landing.

Airliners are a prime example.

However, anti-gravity research has not made much progress in the past few decades.

Sun Zheng thoughtfully agreed with this sentence.

Ning Bei chuckled: "It's better to study alternative energy than to study nuclear energy!" ”

"Our research building is not of this level, and it is very expensive to build." Sun Zheng was a little helpless.

Nuclear energy projects are all tasks at the national level, and almost no one is involved in the field of nuclear energy.

Ning Bei chuckled: "As early as five years, China intends to open up the nuclear energy market, but the investment is large, the approval is difficult, and top talents are needed, and ordinary people can't support it." ”

Sun Zheng smiled bitterly and nodded, this kind of thing is indeed not as simple as talking.

After a few simple preparations, Ningbei went to the teaching building.

Dean-level classes are all large classes, facing the society, and large classrooms with hundreds of seats are equipped with loudspeakers.

The first class arranged by Bianda for Ningbei was a big class in the Department of Computer Science.

On the desk is a new notebook, all of which are configured by the school, and there is a lesson that needs to be explained today.

Ning Bei arrived early and sat on the lecture platform.

The students who kept entering the door were surprised, and then rolled their eyes, thinking that Ning Bei was a troublemaker.

No one would have thought that this guy would be the dean-level lecturer of today's big class.

The thin young man who was passing by said angrily: "Dude, what are you doing, Professor Ning is almost here, don't make trouble, come down and get ready to listen to the class!" ”

"Another dead fellow, beware of remembering that you are too big, there will be no place to cry when the time comes!" Student with black-rimmed glasses rolls his eyes.

Ning Bei sat indifferently and smiled.

As the time came to half-past nine, the last group of students finally entered the door, startling everyone.

The people who entered the door were more than a dozen old men Sun Zheng, Li Deren, and Zhou Jianguo.

Suddenly, the students who made trouble again sat down seriously and did not dare to make trouble.

Ning Bei smiled lightly: "When the time comes, start class, I am Ning Bei, the first time I come to Bianda to teach!" ”
