"But don't be too happy......"

Lin Zifan's next sentence made the smiles on the students' faces instantly freeze.

"The steam engine was made, but ...... Don't you think the steam engine seems to be of little use?"

"Mansion Master!"

Deng Xiaoqiu raised his hand, as the most optimistic one among his male classmates, Lin Zifan tilted his head and said: "I think the steam engine is not completely useless!"

"Although it seems at the present time that the steam engine can only do some simple and repetitive force work, and is not as fast as a woman's hands, it ...... I always felt that there were other uses for the steam engine!"

"Otherwise, you wouldn't have spent so much time studying and making a steam engine. ”

"It's impossible for you, master, to let us spend so much time making a useless thing, right?"

This kid is quite smart?!

Lin Zifan was slightly surprised, indeed, he hadn't told them what the steam engine was useful for, but this Deng Xiaoqiu had already guessed some of the functions.

This is the most common use of the steam engine!

However, the steam engine is of no use other than that? Obviously not! Deng Xiaoqiu's reverse thinking can already determine this!

As soon as these words came out, all the students' eyes lit up, and they looked at Lin Zifan, waiting for his next words.

"Pretty smart. ”

Lin Zifan smiled: "I can already use reverse thinking, it's very good, this represents your growth, I am very happy to be the master of the mansion!"

"That's right, the steam engine is definitely not useless! On the contrary, it is a very useful existence, and it is the beginning of the industrial revolution!"

"What is the Industrial Revolution? You don't need to understand it now, because you won't understand it!"

"But ten or even decades from now, you will always remember the steam engine you made and the era you led!"

"The steam engine is just the beginning!"

"It's more like a key, which will open a new door for you, for Datang and even the whole world!"

"And the next thing I'm going to do for you is...... Locomotive!"

If you want to say that the car with mechanical kinetic energy, what car is easiest to make, it is undoubtedly the train!

The steam train, not too fast, but definitely not slow either!

It's not as fast as the power nature of wildebeests and other beasts, but the train is smooth and at the same time, the load is extremely high!

This is the great advantage of the train, and it is a completely incomparable existence of ferocious beasts such as wildebeest!

How much can a wildebeest carry? What about a train? As soon as dozens of carriages go up, the load is terrifying!

And it doesn't have to be like a car, which requires all kinds of precise control, and runs directly on the rails, which is safe and fast......

For Datang in today's era, the train undoubtedly needs to be made as soon as possible!

After getting it out, it will be more convenient and faster for Datang to sell its own goods to other countries or to transport troops to the front line!

Asphalt roads are good, but railways are also indispensable!

The roles of the two are not in conflict, on the contrary, they will complement each other......

The biggest role of the railway is to ...... Transport!

Just imagine, how many heads of wildebeest are needed for 10 tons of grain? At least four or five! This must be a strong wildebeest!

Moreover, even if it is a strong wildebeest, with an average camel of two tons of cargo, it is impossible to continue to run for too long, and it can run 500 miles a day, which is already considered to be the top of the sky.

But what about trains?

There is no need to rest, and the load capacity is scary!

If nothing else, even two people can control it, and there is no need to rest twenty-four hours a day......

Even if the speed is only a pitiful fifty miles per hour, it is more than a thousand miles a day, right?

Isn't the difference so big that it's not obvious enough?

As for manned ......

As strong as the Praetorian Guard, after rushing from Chang'an to Yanmen Pass, it must rest at least one night before participating in the war.

But if there is a railway, hehe...... Let's just take the train together, you won't be tired at all on the train, and you can even eat and sleep!

After arriving at the place, you can directly open the battle!

This is the gap!

However, now that he said so much, it was difficult for the students to understand, but Lin Zifan did not say much, but just told them that as long as the locomotive was made, they would know how amazing the steam engine was!

"Locomotive, it's your topic for the next two to three months, and it's also your final exam for this semester!"

Lin Zifan stretched his waist: "As long as you can make the locomotive, hehe......"

"The lord of this mansion, nothing else can be guaranteed, but in the future, there will definitely be a place for you in the court!"

Hiss!!!

As soon as these words came out, everyone gasped!

Huo Mei, Shi Li, Yan Wenwen and other female students who were originally important ministers were okay, but other civilian female students were so surprised that they were speechless!

As for the ten male students, they were instantly excited, shocked, and unbelievable!

"The Lord...... This...... Is this true?"

"Above the court, there will be us men...... A place for us, can we?"

Deng Xiaoqiu pointed at himself, and then pointed at the other male classmates around him, his little face was full of disbelief, but with deep longing.

The 'concept' of men being inferior to women, women doing things, and men being housekeepers has long been deeply rooted in the hearts of the people!

Just like during the Tang Dynasty in China, the empress Wu Zetian ascended to the throne, how amazing was the shock?

Now, although Lin Zifan does not guarantee that they can become emperors, he has entered the court as an official...... That's amazing enough!

After all, the officials who can enter the Tang Dynasty are all big officials!

If only all thirty of them could go, and ten men...... How much of a shock will it cause?

"Of course, but only if you can make the locomotive, in addition to the craftsmen...... Any outsider doesn't help on a basis!"

The previous steam engine, with the help of the empress, Lin Zifan just turned a blind eye.

But nowadays, the locomotive is the most important thing, if they can make it themselves, whether it is for the experience of ability or for the future...... All have great benefits!

Naturally, it's up to them to do it themselves.

Of course, if they really can't finish it, Lin Zifan can't be immutable, and proper guidance is also possible.

But only if you do your best!

Do your best, even if you lose!

As for the after......

If they can make a locomotive, they are actually very good, and after the last semester of study, they will ...... Barely able to meet the standard of graduation!
