The room goes through the late Ming Dynasty, and the back door leads to North America at the beginni

Boom, boom, boom...

The time bell rang.

Zheng Sen and Wang Euzhi walked out of the large classroom of the Department of Politics and rushed to the cafeteria.

As for Zhang Huangyan and Yao Qisheng, they transferred to Nanjing Military Academy in August last year.

Nanjing University is currently divided into four colleges: liberal arts, science, engineering, and agriculture.

Under the College of Liberal Arts, there are six major departments: literature, philosophy, politics, law, history, and economics.

Under the College of Science, there are six major departments: mathematics, physics, chemistry, biology, astronomy, and geography.

Because the development of science in Dawei has just started and university education is still in the experimental stage, currently the College of Liberal Arts and the College of Science are only divided into departments and not majors.

The College of Engineering and the College of Agriculture are divided into departments and majors.

The Institute of Engineering currently has departments of metallurgy and engineering.

The Department of Metallurgy consists of majors such as steel smelting, coal mining and application, and alloy smelting.

Under the Department of Engineering, there are majors such as civil engineering, water conservancy engineering, mechanical engineering, and chemical engineering.

The Agricultural College currently has six major departments: grain, fruits and vegetables, animal husbandry, forestry, aquatic products, and medicinal plants. Each department is also subdivided into one to several majors.

The above are all the results of further reforms in university education last year.

After Zheng Sen and four other people completed one year of college preparatory studies, they were faced with the problem of branching into departments and choosing majors.

Zhang Huangyan and Yao Qisheng were both more interested in military affairs.

However, although Nanjing University covers most of the current mainstream knowledge, it does not include military and medicine.

However, Nanjing does have independent Nanjing Military Academy and Nanjing Medical College.

The two submitted their applications, and after passing the exam and interview, they transferred to Nanjing Military Academy to study.

Zheng Sen and Wang Fuzhi entered the Political Department of the Chinese Academy of Arts to study.

The current teaching method of Nanjing University is relatively flexible. In order to facilitate students to learn the knowledge they are interested in, in addition to majoring in a certain department or major, they can also audit and take other elective courses.

Of course, semester exams, graduation assessments, etc. only test majors.

At this time, Zheng Sen and Wang Fuzhi were discussing elective courses.

"Brother Wang, are you going to attend the Philosophy Department class this afternoon?"

Wang Fuzhi nodded, "Of course."

Zheng Sen was a little confused and said, "I also listened to a few lessons in this philosophy department with Brother Wang, and I feel that most of them are the Confucian content we learned before. Now that science is flourishing, why does Brother Wang still study Confucianism?"

Wang Fuzhi smiled and said, "Confucianism is actually included in the sciences. Just like the courses in the philosophy department, they not only include part of the content of Confucianism in the past, but also part of the content of hundreds of schools of thought in the pre-Qin period."

"In my opinion, philosophy can reveal the changes in ancient people's thoughts and make people today live more transparently. It is quite beneficial to study it."

"Live more clearly?"

Zheng Sen frowned slightly and thought, but still had difficulty understanding Wang Fuzhi's preferences.

In addition to philosophy, Wang Fuzhi also took history as an elective.

He also liked taking classes in the history department, but classes in the philosophy department made him feel that it would be better to listen to Confucian classics taught by a great Confucian scholar.

However, besides politics, Zheng Sen is most interested in economics, so he often attends classes in the economics department.

There was no class in the Department of Economics this afternoon, so Zheng Sen wanted to go on an off-campus trip with Wang Euzhi, so he wanted to persuade Wang Euzhi to skip the class in the Department of Philosophy.

Unexpectedly, his persuasion failed, and instead Wang Fuzhi led him into the "fog of philosophy."

Regarding Wang Fuzhi's words, Zheng Sen put them aside after thinking for a while and said, "Anyway, the philosophy class in the afternoon ends at three o'clock. It's still early then. Why don't we go for a walk outside the school together?"

Worried about Wang Fuzhi's rejection, he added, "We haven't left school for several days."

Wang Huizhi smiled and said, "My dear brother invites me so kindly. As a brother, it is better to be respectful than to obey."

"Hahaha···"

The two of them smiled and walked to the school cafeteria.

In fact, with Zheng Sen's wealth, he could order meals from restaurants outside the school.

But in order to avoid estrangement from his classmates, such as Wang Euzhi, who came from a more ordinary background, he always ate in the school cafeteria.

Of course, the food in the school cafeteria is not terrible, it is even delicious and affordable. But it is definitely incomparable to the signature dishes and famous dishes of those big restaurants.

After lunch, the two returned to the dormitory and met their two roommates.

They all moved here after Zhang Huangyan and Yao Qisheng left.

One is named Li Xiangen.

Born in the first year of Tianqi (1621), he was born in Suining, Sichuan.

He was born into a family of officials, and his maternal grandfather was Lu Daqi, the current governor of Guizhou.

Li Xiangen actually majored in politics, but he was delayed by something after school, so he didn't go with Zheng Sen and Wang Euzhi.

The other person is named Yu Guozhu.

Born in the fourth year of Tianqi (1624), he was born in Daye, Hubei.

He also came from a wealthy gentry family, but he only met Zheng Sen and Li Xiangen, so his family background was nothing.

Yu Guozhu majored in economics and had no class in the second period in the morning, so he had lunch earlier.

The few of them chatted for a while and learned that Zheng Sen wanted to go on a school trip in the afternoon, so they made an appointment.

Stay until three in the afternoon.

Wang Fuzhi came back from the philosophy class, and the four of them left the school together.

Zheng Sen, Li Xiangen, and Yu Guozhu all have bookboys renting accommodation near the school so that they can easily handle affairs for the three of them. Zheng Sen even has guards.

Now that the three of them were out of school, they naturally called the book boys and guards.

It's not that I'm worried about safety, it's mainly that someone can take the things I buy.

Only Wang Fuzhi, who was alone, looked more relaxed.

"Go to the National Library to return the books first, and borrow a few more books by the way."

Wang Euzhi suggested.

"it is good."

The other three people had no objection and walked to the National Library together.

Halfway down the road, I saw a burst of noise and exclamations from ahead, interspersed with strange ringing sounds.

"Make way! Make way!"

Someone shouted.

Not long after, this series of sounds came head-on.

But it was a man riding a weird two-wheeled vehicle, riding down the street.

This car seems to be made entirely of steel. It has two wheels, front and rear, but it can run. It looks very weird.

In fact, the speed of the strange car is not very fast, but the man riding it is swaying from side to side, as if he will fall down at any time.

Fortunately, the road is wide enough.

There are separate roads for pedestrians, vehicles and horses, and traffic is carried out in an orderly manner in accordance with the rules of the Ministry of Transportation.

Otherwise, this man and the strange car would have hit someone long ago.

Zheng Sen and others' eyes lit up when they saw it. They didn't come back to their senses until the strange car was gone.

"What kind of car is this?" Zheng Sen asked with interest.

Wang Fuzhi and others looked at each other, but no one could answer.

Zheng Sen then sent a bookboy to inquire.

After a while, the book boy came back and said excitedly: "Master, that strange bicycle is said to be a bicycle made by the Royal Factory. It was only put on sale in the market yesterday."

"bike?"

The book boy was smart and knew that Zheng Sen and others did not know the meaning of the word, so he explained: "It is a car that walks on its own."
