"Lao Du, I can't reach it, hug me!"

The title was written too high, and Liu Lang stretched out his arm and was more than 30 centimeters away.

"Haha!"

The rest of the students burst out laughing.

Juniper hurriedly picked up Liu Lang, Liu Lang took the chalk and wrote quickly below, one question was solved after a minute, and the other question took a little longer, but Liu Lang also wrote the answer two minutes later.

"Oops, I'm tired!"

Seeing that Liu Lang finished writing, Juniper put Liu Lang on the podium as soon as he let go of his hand, and then kept rubbing his arm, he was a dead eye, and he didn't know how to take a break halfway.

"Well, well, you'll be able to do that too?"

Xiong Huaizhi pointed to the question that Juniper hadn't answered just now.

"I flipped through the content of Chapter 3 yesterday and learned a little bit, Professor Xiong, if you take the content of Chapter 4, I won't be able to. ”

For Liu Lang, as long as the knowledge written in the textbook, he can only understand it two or three times at most, and then do a few related questions, then these knowledge points will be fully integrated, and the learning ability is several times stronger than that of ordinary students.

"Look at the two of you, not even a three-year-old......... Get back to your seat and we'll have class!"

In the face of such a "demonic" Liu Lang, Xiong Huaizhi was helpless.

"You're not even as good as a three-year-old child!" is often on the lips of those teachers, and this is not sarcasm, but a fact!

When the bell rang for the end of class, everyone breathed a sigh of relief, the same class lasted for an hour, but Xiong Huaizhi's class felt like it had spent half a day, and everyone began to pack their schoolbags and wanted to leave immediately.

"Today's homework, you go back and finish these three questions, and I want to ask questions in tomorrow's metallurgical class!"

Xiong Huaizhi writes the question on the blackboard.

"Ahh

Everyone exclaimed in a low voice, these three questions are very difficult, and if you want to do it, I am afraid you have to prepare a lot of courses, if only a few more days, but this old bear takes three courses alone, almost every day, and he can't escape.

Let's go!

The students, who had just been a little happy at the end of class, left the classroom one by one and walked towards another classroom.

"Liu Lang, let's go!"

Juniper walked over and said to Liu Lang.

Juniper is not young, he is also the eldest at home, and there are two younger brothers and a younger sister below, the youngest of which is as old as Liu Lang, so he really has a set of children.

Liu Lang is still very young now, and he can't do a lot of heavy work, and his mother can help after school at night, but during the day, a lot of work is done by Juniper, such as being late for class before, so he simply picked up Liu Lang.

So his role now is similar to that of a bodyguard, responsible for Liu Lang's pick-up and drop-off tasks to and from school, and he is as careful as a hair, treating Liu Lang like a younger brother.

"Lao Du, the next class is dialectics, Liu Lang won't go to class!"

A classmate next to him walked over, then lowered his head and whispered to Liu Lang: "Liu Lang, will you do these three questions?"

"I haven't seen it yet, I don't know!"

Liu Lang shrugged.

"Hurry up, I'll ask you again in the canteen at noon!"

The other party touched Liu Lang's head and left.

Liu Lang really didn't take any courses on materialist dialectics, not only did he not take this course, but he also didn't take any courses like "Marxism-Leninism" and "philosophy", and the teachers who were very dissatisfied at the beginning of the school year.

Zhao Tianming personally came to ask what was going on, Liu Lang took these books, and then after turning three or four pages, he directly memorized them, and the result was word-for-word.

Liu Lang's move made several teachers speechless on the spot.

Liu Langdu has lived to be almost 40 years old, and the three views have long been formed, and he still needs to learn these things? In the time saved, he still has to learn useful things, such as learning German and Japanese at the foreign language college.

"Liu Lang, you stay first, and the others hurry up!"

Suddenly, Xiong Huaizhi appeared at the door again and said loudly to the people inside, it turned out that he had just run to the door to smoke, he was very addicted to smoking, and he had to smoke two cigarettes during the break in class.

Lao Xiong's sudden appearance scared all the students away, and only Liu Lang was left in the classroom.

"Professor Xiong, are you looking for me?"

Liu Lang was originally going to go to the electrical department to audit a circuit class.

"Liu Lang, what do you want to do when you grow up?"

Xiong Huaizhi walked to the stool near Liu Lang and sat down and asked.

"Professor Xiong, I want to be an engineer when I grow up and make the most advanced machine in the world. ”

"Hehe, you have great ambitions! Yes, yes, if you study diligently, you may be able to fulfill your wishes, but I can't see it......... By the way, I have a book here, if you can read it, you can read it!"

He took out a book from a cloth bag and handed it to Liu Lang.

The book turned out to be an all-English book, with the cover reading "A Brief History of Modern Industrial Development".

"I bought this book when I was in the United States, although the technical aspects are a little outdated, but a lot of experience is still worth learning, you are good at English, you should be able to understand it by looking through the dictionary, if you have time, read it!"

"Thank you, Professor Xiong!"

Liu Lang hurriedly took it.

"Remember, industry is the foundation of a country, and if you want to develop, you must do your best, relying on the strength of a few people...... That's far from enough, our country is not too aware of the importance of industry now, and it is still far from ...... if we want to become an industrial power. ”

Xiong Huaizhi shook his head and stood up to leave.

Liu Lang did not leave the classroom, this classroom was originally a small classroom, only more than 30 seats, no one came to class during the day, he sat there and opened this book of a brief history of modern industry.

The professional books in English are still a little difficult for Liu Lang, mainly because he has not read some special words, and the entries included in the English dictionaries bought on the market are not too complete, but there is no problem with his grammar, and he can understand it through the understanding of the context, so although it is a little difficult, there is not much problem.

As Xiong Huaizhi said, the book does not have much to say about the technical aspects, but mainly an overview of the industrial development process, from the invention of the steam engine to the end of World War II, the tremendous progress of nearly 170 years.

Twenty or thirty years later, many young people are making noise on the Internet, saying that the country can't even build a decent car engine, it must be that the country has focused on real estate, and has neglected the development of industry in order to make quick money.

There is some truth in this statement, because the country has indeed been a little lax in the basic industry in the more than ten years after the reform and opening up, although it has also vigorously developed steel, but there is basically no breakthrough in smelting technology, and there is a lot of quantity but lack of quality, but even if the country attaches importance to steel smelting technology, if you want to catch up with Western countries in just ten or twenty years, it is also a fool's dream.

Why? That's the answer in this book.
