The National Library is less than five kilometers away from Chu Bai's house.

Riding a bicycle, Chu Bai drove on the street.

What caught his eye was a strange scene of vitality and competition.

A large number of steam cars, making tractor-like sounds, drove on the concrete-paved ground. There are also a few sparse electric cars, which are very smooth and surpass the steam cars.

On the slightly uneven concrete floor, there are cracks left by the erosion of time, and several workers in workers' clothes are filling the cracks with cement.

Pedestrians on the street wore horse coats similar to those of the Republic of China and walked in a hurry. In addition, there are those who wear blue workers' suits, those who wear suits, and those who wear tunics.

This kind of scene is too magical, and it is very different from the Shenzhou in Chu Bai's memory in his previous life. It is more like the intertwined collision of the Republic of China in the previous life and a period of time after liberation.

"Wait a minute," Chu Bai suddenly thought of something, and was shocked, "Electric car, steam car...... In this world, there are no internal combustion vehicles? ”

How can it be......

How could there be no car loaded with an internal combustion engine?!

When he came to the library, Chu Bai did not go to the historical area for the first time, but went to the industrial area first.

"Let me see." Chu Bai's hand crossed the names of the books, and suddenly in a book "The Beginning and End of the Industrial Revolution? The real founder of industry is him".

Pulling out the book, Chu Bai sat on the chair and looked at it with a serious expression.

Many of the contents of the book are covered in the 12-year compulsory education, but those are very rough, and the book deeply analyzes the process, development, and major turning points of the industrial revolution.

Li Jianxue started the industrial revolution and set off a vigorous transformation of the Datong Dynasty into the bone marrow. Also, it is said above that many people have misunderstood, saying that the steam engine was not made by Li Jianxue, and the steam engine was cast by the first emperor Chen Kang, and it can even be said that it was the first emperor who laid the foundation of the industrial revolution. ”

"If it weren't for the invasion of ten thousand demons, the establishment of the Great Qian Dynasty interrupted the industrialization process, and it would have been the Chu Empire that started the industrial revolution."

Sure enough, the textbook doesn't say anything about this at all...... Chen Kang was estimated to be dizzy when he saw it. He must also want to be called the founder of the Industrial Revolution! As a result, peaches were picked. ”

Chu Bai muttered in his heart, anyway, if he changed him, he would definitely not be convinced...... At least when he saw that the textbook didn't mention it, it was he who laid the foundation of the industrial revolution, and he was definitely not convinced. After all, the textbook has a spring and autumn penmanship, and the credit is Li Jianxue's from beginning to end.

However, Chu Bai was also thinking, was this Li Jianxue's own greed for heaven? It is possible, but it is also possible that the imperial court consciously increased the sanctity of the founding ancestor. Li Jianxue was greedy for the merit of heaven.

After all, Chu Bai is not a party to the matter, so he doesn't know these aspects very well.

"Also," Chu Bai flipped through the catalog, his expression became serious, "In the book, there is really no internal combustion engine. ”

What is an internal combustion engine? It is the core of the second industrial revolution.

In contrast, electricity is also at the heart of the Second Industrial Revolution. However, in the previous life, until the end of the third industry, in the 21st century, the battery storage capacity increased significantly, and new energy electric vehicles gradually began to popularize and replace internal combustion vehicles.

In other words, before the Third Industrial Revolution, automobiles had an overwhelming advantage over electric cars.

The current situation is unless......

Chu Bai realized something, his expression became serious, he took out a few books again, and flipped through them. Then he was shocked.

"Wait a minute, there's oil in this world?"

At first, Chu Bai thought that there was no oil in this world. But if there is, then why......

Well, it may also be because the time that Li Jianxue crossed was about the same time as the time he crossed, and it also reached the stage of the official promotion of new energy vehicles. So maybe, Li Jianxue forced a plan and prepared to forcibly cross the car to the tram. But......

"This still doesn't explain why the industry-related books I read don't use oil!"

Chu Bai's expression was serious, oil, the definition in the books of the Datong Dynasty, is a black fluid substance that can be ignited. But there is no other explanation.

This is very unreasonable!

Petroleum not only refines the gasoline that drives cars, but also produces a large number of products of modern society. For example, plastics, fertilizers, and even clothing.

Oil is the lifeblood of modern industry.

"Li Jianxue, it's impossible not to know the usefulness of oil! But why not take advantage of ......"

After having a headache for a long time, Chu Bai flipped through several other books introducing industry, and the content was similar. Not much different from the industrial development process of the previous life...... But the only thing that doesn't introduce the unbelievable industrial characteristics of oil is not mentioned.

It's like, on the industrial side, oil has been deliberately avoided.

"If it's not that I'm crazy, it's the world that's crazy." Chu Bai muttered to himself in his heart.

After all possibilities have been ruled out, the remaining answer, no matter how unbelievable, must be the truth.

So, there is a problem with the oil of this world?

"If you go to college, you might want to consider asking your teachers!" Chu Bai's thoughts were full of thoughts.

After putting the industrial books back one by one, Chu Bai went to the miscellaneous book area again and checked the situation of those "famous books" that he felt familiar, and the date of production. After thinking about it, Chu Bai came to the history book area again.

Then, he pulled out a copy of the Book of the First Emperor. This is dedicated to the First Emperor.

After hesitating for a moment, he pulled out the record of Taizu of this dynasty, as well as many of Li Jianxue's works, Datong Anthology, my autobiography, and so on.

Chu Bai found a corner where no one was there and watched patiently.

"Should I say so? Although there are many things recorded, many times more detailed than those written in the history books, there is nothing I care about. Chu Bai muttered to himself in his heart.

But this is also normal, this kind of serious biography, how can it be written that this person is actually a traverser, and what doubts does he have about crossing?

Of course, the Datong anthology, Chu Bai always felt very immediate, a bit like the previous life...... Well, it's a bit like that book, but it's very different.

It can only be said that the two ideas are the same.

This book is rooted in the countryside in the years before the founding of the Datong Dynasty, and the problems and experiences described above, the experiences and these problems and experiences are all things that Li Jianxue has really experienced, encountered, solved, and saved......

It was getting dark.

Chu Bai woke up suddenly, only to find that the library was empty.

There was an oil lamp lit next to him, Chu Bai glanced at it secretly, and found that the person sitting on the other side, reading through the oil lamp, was an old man in an old Mao suit.

The old man's tunic was a little whitish, and there were some patches on it, but it was very neat, and there was not even a single fold on it.
