The Tang Dynasty started from saving Empress Changsun

Chen Jingke has been busy with two things recently, one is the construction of Gewu College, and the other is building a factory.

The actual construction work of Gewu College is in charge of the supervisor, using the craftsmen who built the Daming Palace, and the building materials are also Daming Palace materials.

Even the design drawings of the academy were personally in charge of by Yan Lide.

Chen Jingke put forward functional requirements, and Yan Lide designed and constructed it, which can be said to be very demanding.

With such a boss in charge, Chen Jingke naturally didn't have to worry so much.He just went to have a look occasionally and suggested a little modification on the details.

After more than two months of rushing work, the academy was finally built a year ago, and Chen Jingke took people to check and accept it early this morning.

The students in the Gewu class also asked to come together when they heard that their own academy had been built.

Chen Jingke didn't refuse either, so he took everyone to set off to the destination.

Walking ten miles north-west from Fanglin Gate, there is a Longshou Mountain, about sixty miles long, with a height of one hundred meters at the highest point, but generally only a few tens of meters high.

It is not so much a mountain as it is a bump on the ground.

But it is still a natural barrier in the north of Chang'an. The Royal Garden Longshou was originally in the embrace of Longshou Mountain.

Gewu College is at the foot of Longshou Mountain, which is Chen Jingke's chosen location.

Firstly, it is safe enough, secondly, it is away from the prosperity of Chang'an, and thirdly, there is enough space for students to experiment.

Chen Jingke's long-term plan is not just a Gewu College, but a collection of medical colleges, liberal arts colleges, agricultural colleges and other colleges.

To put it bluntly, it is a school city.

By the way, some factories can also be built as experimental bases for students.

The new factory he asked Taoism to open is also at the foot of Longshou Mountain, which is convenient for students to actually visit.

However, for safety reasons, the location of the factory is even more remote, more than 20 miles away from Chang'an, which is already out of the scope of Longshouyuan.

Chen Jingke, Li Tai, and Cheng Huailiang took the students to the location of the academy on an outing.

When walking halfway, Li Tai let out a long breath and said, "It's too far away. The key is that there is no boat. It's too troublesome to go back and forth."

Cheng Huailiang looked at the students who were out of breath, and said, "Yes, it is more convenient for us to have horses, and it will be difficult for students to go to the city."

Chen Jingke said slowly: "Next year I plan to build a train here."

Li Tai was stunned for a moment, and then said in disbelief, "What? Repairing the train? Really?"

Others also looked over.

Under the gaze of everyone, Chen Jingke nodded slightly and said: "Yes, build a train, and it will be convenient for everyone to communicate."

After thinking about it for a while, Li Tai shook his head and said, "It's not cost-effective. It's too extravagant to build a train just to facilitate the passage of these people from the academy."

Cheng Huailiang also nodded and said, "Yes, that's an iron bump. It's hard to say whether the annual output of a large iron factory is enough to repair this rail."

The other students also thought about it. They had discussed the railway in private for countless times. It was indeed a good thing, but the cost was too high.

It's unbearably high.

Now it is too extravagant to build a train just for the convenience of the academy.

Chen Jingke said with a smile: "Who said that this railway was built specifically for the academy? It was built for the factory twenty miles away. It just took a detour and passed the academy."

Li Tai still shook his head and said, "I know the factories you mentioned, but they are still not cost-effective. The cost of this railway, those factories will not be able to make back the cost in a lifetime."

Chen Jingke said bluntly: "Short-sighted, you know that those factories will not be expanded and will always be small workshops?"

"And this railway is not only for transportation, but also the key to unlock the wisdom of the people..."

"Think about it, if the people of Chang'an can see trains passing by every day, what a big impact it will have on their cognition?"

"In the long run, the world's prejudice against Gewu will gradually be reversed."

Speaking of this, he raised his voice and said: "The great prosperity of Gewu started from this railway."

"Okay, what the real person said is great." The others cheered up and said one after another.

No one wants to see Gewu Daxing more than them, after all, the stakeholder groups.

Li Tai was still not so optimistic, and said: "Your idea is really good, but have you ever thought about the cost, where are you going to get so much steel?"

Chen Jingke looked at him and said with a smile: "It seems that you are already a qualified Gewu scholar."

Li Tai looked at him puzzled, what are you talking about?Why can't I understand.

Steel is the embodiment of a country's strength. Li Tai didn't even know about such an important matter, which shows that he really gave up the idea of ​​seizing the heir, and devoted himself to the research of Gewu.

That's why Chen Jingke said that he is already a qualified scholar.

There are so many people here, he didn't say too much, he just said: "In the past two years, the imperial court has opened more than ten new iron ore factories, and adopted new mining methods, new methods of frying steel... The output of steel has more than doubled."

"Although the construction of the railway requires a lot of steel, it is still no problem to ask the saint for some iron to repair a piece of iron in my face."

"And this time I'm not going to build standard rails, but light rails. You only need to run small trains on them, which can save one-third of the steel."

In his previous life, he was a senior donkey friend. He had traveled and explored many places, and he knew the locations of some well-known iron mines.

He also drilled through many karst caves, and later crossed because of this, and saw the traces of boiling salt left by the predecessors in many karst caves.

The information in the previous life is useless, it can only be used as a talking point in a small circle, but in ancient times it was the most important information.

Thanks to the information he provided for the newly built iron ore factory in Datang.

Most of the saltpeter needed to produce gunpowder was also mined from the caves he provided.

Continuing to talk about steel, the most important iron ore plant in Datang at this time is the Shilu Iron Mine located on Zhuyazhou (Hainan Island).

Although the output of the Shilu Iron Works was not very high when it was established relatively late, the quality of the iron ore here is too high, and the refined steel is also of higher quality.

Therefore, it is basically used to cast artillery and make weapons and armor, and it is rarely sold out.

The few that flowed out were also used in special places, such as the watch workshop in the hands of Changsun Wugou.

Of course, these are all top-secret information, and Chen Jingke did not tell everyone.

Hearing his explanation, Li Tai also had to admit that what he said made sense.

Moreover, for the emperor and his ministers, this railway is also the best experimental product, which can actually verify the function of the train and prepare for the construction of a real railway in the next step.

Thinking of this, he finally nodded and said: "You are right, there is indeed a lot to be done about this matter."

Seeing that he was convinced, the other students cheered.

This is the railway they have discussed countless times, how can they be unhappy.

Looking at the excited crowd, Chen Jingke said: "Don't be too happy, you will be busy next time, we have to build at least two light trains."

"You can't ask others for help in this kind of thing, you can only do it yourself. Not only do you have to make the train, but you also need to understand the principles and draw detailed structural drawings."

Hearing this, everyone became even more excited, and said, "Don't worry, Daoist, leave this matter to us, and you are guaranteed to be satisfied."

"That's right, we've built countless miniature train models, and we've wanted to build real trains for a long time."

Chen Jingke nodded, and then said to Li Tai: "How? Are you interested in leading a team to make real trains?"

Li Tai said proudly: "Besides me, can you find other people to lead the team?"

Chen Jingke laughed loudly and said, "I'm relieved seeing your proud appearance...Students, take a big step and go to our college."

Everyone who was still a little tired was revived with blood, and went to the academy happily.

The further you go to the northwest, the more desolate it will be, but fortunately, there are ready-made roads, so you won't get lost.

It took two or three hours to walk and rest to reach the academy.

Just looking at the scale of the land and the luxurious buildings, everyone couldn't help but exclaimed.

It covers a very large area, and it can accommodate tens of thousands of people to study and live, but there are only a few dozen of them.

Next year, the enrollment will be tripled, and the total number will only be more than 200.

Living in such a big place is really too extravagant and wasteful.

Chen Jingke was very satisfied with everyone's performance, and said: "Do you think it is too big? It is indeed too big now, but I hope that everyone will think it is too small in ten years. Whether you can do this depends on you. "

"You are the seeds of Gewuxue and the future of Gewuxue... I have said this countless times, and I don't want to repeat it anymore."

"But I hope you will always remember this sentence and study hard for the prosperity of Gephysics."

Everyone said solemnly: "Here, I would like to follow the real person's teachings."

After feeding everyone the chicken soup, Chen Jingke came to the front door and knocked on the door.

The craftsman guarding the gate knew him, so he quickly opened the door and said, "Your Majesty is here, come in quickly."

Chen Jingke led everyone into the gate and began to visit the entire academy.

The space inside is very large, and the overall layout is mainly spacious and bright.

The entire academy is divided into several different areas, such as faculty area, teaching area, dormitory area, stadium, living area, etc.

Various buildings are also very complete, including canteens, libraries, laboratory buildings and the like.

There is even a workshop area specially divided, with an ironmaking room, a huge workshop building, and tools such as hanging rails in the factory building.

In addition to the above, the garden is also indispensable, with many plum trees planted.

An artificial lake was even excavated specially, and some koi carp would be thrown into it for raising.

In short, Chen Jingke has built all the areas that colleges and universities should have that he knows.

But right now, most of the areas are unusable and can only be closed for the time being.

But he believes that one day the academy will not be able to accommodate so many students, and more branch campuses will be built next to it.

After that, everyone went to visit classrooms, dormitories, canteens, libraries and other places.

The classroom is not big and can only seat 50 people. This is because the classroom is too large and too many students will affect the teaching.

If large classes are required, there are larger multipurpose rooms available.

The dormitory is similar to that of Zixiao Temple, a room for four people, the lower bunk is a table, the upper bunk is a bed, and each person has a cabinet for personal belongings.

The library is even more spacious and bright, and can hold [-] books.

But everyone soon discovered something strange, and Li Tai took the lead to ask, "What is this under the window? It looks like a pottery pipe?"

Chen Jingke smiled complacently, and said: "It is indeed a pottery pipe, but it is not an ordinary pottery pipe, but a pottery pipe with iron ore soil added, which is more durable."

Li Tai was puzzled and said: "If I remember correctly, there are these things in all buildings. You definitely won't repair useless things. What is this for?"

Chen Jingke didn't care, and said, "This is the heating pipe."

Li Taisi asked: "Heating? For heating? How do you use this thing?"

Chen Jingke said: "Fill it with hot water, and the heat in the water will be transferred to the air to heat the room temperature."

Cheng Huailiang asked suspiciously: "But how to pour hot water into the pottery pipe? And the heat of water is limited, what should we do after the temperature drops?"

Everyone expressed the same doubts, only Li Tai was thoughtful at first, and then suddenly realized.

Chen Jingke did not answer directly, but said: "Actually, the method is very simple. It is to use a machine that you have seen and studied. You may wish to guess."

Everyone frowned and thought, have they seen the machine they studied?what exactly is it?
A flash of inspiration flashed in Zhao Youchang's mind, and he thought of something, and quickly said: "The water pump must be a water pump, as long as a water pump is used to pump hot water into the pottery pipe."

Everyone also suddenly realized, and said: "That's right, why did you forget about the water pump... Really, is it a water pump?"

Chen Jingke smiled and said: "Yes, it is the water pump. There is a house in the living area dedicated to burning the boiler, and the water inlet and outlet of the clay pot are connected to the boiler."

"As long as the water pump is used to pump hot water into the ceramic pipe, the hot water circulation can be realized. This will continuously heat the air and achieve the effect of keeping warm."

Li Tai said in amazement: "Your idea is really too peculiar, it is clearly a ready-made tool, and it can always play a greater role in your hands."

The others also nodded.

They know that boilers are used to heat hot water in public bathhouses.They also know that there are simple water pipes in Zixiao Temple.

They are more familiar with the water pump, and they have built it by themselves.

But they never thought that the combination of these three things could turn into a safe and effective heating device.

Chen Jingke said: "So your understanding of Gewu is still very shallow, or there are still misunderstandings."

Everyone looked upright and listened attentively.

"It's not your fault. It should be said that it is a common characteristic of all scholars, arrogance."

"I always think that knowledge is used to do big things, and to solve trivial matters is to be inferior to talent and an insult to learning."

"In fact, this is the greatest ignorance. The real role of learning is to change people's lives and make people live better."

"It's something useful that can make people's basic necessities of life more convenient and comfortable. Even if it's just a toilet that can flush, it's worth the money."

"So I hope you can let go of the arrogance in your heart, start from the subtle, and change the world and people's lives bit by bit."
