Du Chensheng, Xu Liang, the two of you live in a bedroom, and you can discuss the beds. ”

The teacher led Du Chensheng and Xu Liang into a dormitory, with an area of more than ten square meters, one left and one right, two wooden beds, two sets of tables and chairs, two cabinets, with folded bedding on the bed, a wooden basin under the bed, and two candles on the table.

Candles are not lit at night when studying, there are no electric lights, candles and oil lamps provide too little light, and it is stated in the school rules that there is something to do during the day and rest well at night.

The bedroom is not big and clean, but Du Chensheng and Xu Liang feel that this bedroom is already very good, even better than their own home.

The residence made Du Chensheng very satisfied, and it didn't take long for Du Chensheng to be surprised by the "water room" in the dormitory building, and when he turned on the faucet, the water automatically flowed out of the faucet, which was tap water.

The tap water used by Guangzhou University is very simple: a water tank is placed on the tallest building of the university, and then the water is connected to the water tank with an iron pipe, and the water flows from the top to the bottom, which becomes tap water.

It is also very simple to fill the water tank at a high place, there is a well on campus, and the A steam engine pumps the water out and sends it to the water tank, which is the simplest tap water technology.

This tap water technology is simple, but it can't be used on a large scale for the time being, let alone let all residents in Guangzhou City use tap water, but it's no problem for Guangzhou University to beat teachers and students to experience the charm of technology.

In the water room, the new students discussed how to get the tap water, and some of the students quickly thought that the waterfall water flowed from high to low, thinking that someone had brought the water to the top of the building, and then the water flowed down from the roof.

However, some students think that it is more troublesome to use water in this way, and it is better for them to go out and fetch water for themselves.

The students could not have imagined that there was a mechanical device in the world that could greatly save manpower to deliver water from a low place to a high place.

In the evening, Du Chensheng and his classmates came to the cafeteria together, learning from others to pick up a wooden plate and come to the place where the food is placed, how much you want to eat can be played by the canteen staff, the staple food is rice, flatbread can be selected, the dishes are meat and vegetarian, there are many vegetarian dishes, meat dishes only have one fish and one meat, except for meat dishes, everyone is rationed, rice and vegetarian dishes can continue to come over after eating.

The good food and good food directly made Du Chensheng and his roommate Xu Liang have a great appetite, and they finally walked out of the cafeteria with their stomachs covered after eating one by one, no one would laugh at them, and the same was true for the students who came first, and they would not be like this again after eating a few meals.

Du Chensheng was satisfied with the living conditions, and the food was even more satisfying to Du Chensheng, lying in bed, Du Chensheng was already fantasizing about the university life that officially began on the first day of February.

Soon, on the morning of the first day of February, the opening ceremony of the first class of students of Guangzhou University, teachers and students gathered in the auditorium of one of the annexes of the university, and hundreds of teachers and students occupied less than one-third of the hall.

When Fang Nan walked to the front desk, the teachers were the first to stand up, and the students immediately understood that the person who stepped up to the front desk was the president of Guangzhou University and the governor of the People's Army, and they all stood up one after another.

"Hello teachers, students, please take a seat." Walking to the center of the front desk, Fang Nan said to the teachers and students with excited faces.

Seeing that both the teacher and the students were seated, Fang Nan continued:

"Today is the first day of the second month of February, the opening date of Guangzhou University, you are the first batch of students of Guangzhou University, you graduated from primary school a few months ago, because you want to learn more knowledge, you gathered here.

University is a place to learn knowledge, and the more knowledge you learn, the more you will know about the world you live in, and when you accumulate enough knowledge, you will be able to make a difference in this world.

There is a water room on each floor of your dormitory, and there is running water in the water room, and when you turn on the faucet, there is a steady stream of fresh water flowing out of the faucet, and any student can tell me that the tap water flows from the faucet. ”

Hearing the Governor's words, the students sitting in the audience habitually raised their right hands.

"Okay, you can answer this classmate." Fang Nan pointed to a student in the front position.

The student stood up and said in a trembling voice, "Principal, I think tap water is similar to a waterfall, it flows from high to low, and a water tank is placed on the roof of the dormitory building to fill the water, and the water can flow down through the pipe." ”

"And how did the water in the roof tank get there?" Fang Nan asked again.

The student who stood up was hesitant and did not say anything, originally he thought that someone had brought the water up, but if it was so simple, it would be impossible for the Metropolitan Governor to ask this question.

"This student, please take a seat, can the other students answer this question?"

No one raised their hands again.

Since the students don't know this question, I have the answer to the question, the water in the roof tank is not manually picked up from downstairs, but uses a machine called a steam engine to draw water directly from the well and send it to the water tank at a high place.

Some students may know a tool called a waterwheel, and the steam engine is more than ten times more complex than the waterwheel.

Some of you will come into contact with the steam engine in the future learning process, and the role of the steam engine is not only to draw water, but also the role of the steam engine is many, many, and the time is limited, so I will not explain them one by one, but you will have the opportunity to contact them one by one in your future life.

Even after you learned something in college, you were able to make a steam engine yourself.

The People's Army has grown from weak to strong, and the poor people who occupy the vast majority of the world are the foundation of the People's Army, but the People's Army defeated the Ming Army by relying on the weapons equipped by the People's Army, and the most powerful weapon equipped by the People's Army is the Tiger Head Gun, which has a longer range and greater power than the musket equipped by the Ming Army.

The biggest reason why our People's Army can have muskets that are even more powerful than those of the Ming Army is that we have more knowledge and we can build better muskets ourselves.

The role of knowledge is not only in the steam engine and the musket, but also in the knowledge you learn, you can cultivate crops with higher yields per acre, you can make all kinds of convenient tools, and you can even explore the rules unknown to this world.

Maybe one day in the future, you will be able to put a pair of wings on people and fly freely in the sky; Maybe one day in the future, you can climb on the moon hanging in the sky and explore the Guanghan Palace to see if Fairy Chang'e lives there.

We can set a goal for ourselves, and this goal is our dream, for this dream, learn more here, and then go and fulfill our dream......"
