"Your Majesty, the color-changing ink, suspension engraving and printing we have basically researched out, and now we are making molds, and it is expected that the day after tomorrow at the latest, we will be able to see the first batch of samples!"

"Hmm!"

Zhu Gaoyi came to the Ministry of Industry alone, and specially called Zhang Qixin by his side and asked him to introduce the progress of this time.

"When the time comes, send the manufactured samples to the imperial study as soon as possible!"

In less than ten days, all these technologies have been solved, and Zhang Qixin has to say that he is still a talent in this area.

"Besides, I have a batch of things for you to do!"

The manufacture of banknotes is only the first step, and the subsequent transportation, railways, guns, and automobiles all have to be manufactured.

"Your Majesty, is it something new?"

"Follow me and you'll know!"

During this time, Zhu Gaoyi often parachuted into the Ministry of Engineering, and after Zhang Qixin saw Zhu Gaoyi, he was not as cowering as he was at the beginning.

Zhang Qixin followed Zhu Gaoyi and came to a small house next to the workshop.

After Zhang Qixin closed the door, he respectfully came to the other side of the table, and Zhu Gaoyi had already put the drawings on the table and slowly unfolded them.

"Can you tell what it is?"

He hadn't started his pen for a long time, and Zhu Gaofu wasn't sure if his painting was not imaged.

To put it simply, it's a simple steam engine.

"This ......"

Zhang Qixin's eyes wandered over the drawing, and his fingers also followed the direction of the drawing, pointing and pointing.

"Your Majesty has drawn a cauldron, and only the cauldron has a lever attached to it?"

"When you boil this water, the heat in the pot will push up the lever and drive the power to the other end, and then the lid will fall and the cycle will go on and on?"

Zhang Qixin looked at the drawings, and then at Zhu Gao, it seemed that he had drawn such a thing, but what was the use of this?

Talented!

When he heard Zhang Qixin say this, Zhu Gaoyi couldn't help but admire in his heart.

Just by looking at this rudimentary drawing, you already understand the principle of this machine!

With a little enlightenment, you might be able to influence something more useful.

"That's right, I really didn't misunderstand you!"

Zhu Gao's tone was quite impassioned, pointing to the lever on the drawing.

"The other end of this lever can be connected to a lot of things, such as the most common - wheels!"

Zhu Gaoyi immediately picked up the pen and drew a lever connecting the wheels in the corner of the drawing.

"Your Majesty, Weichen understands!"

Not yet, when Zhu Gaoyi finished painting the wheel, Zhang Zhang Qixin seemed to suddenly realize.

"Your Majesty, Weichen knows, you are really a genius, as long as the water in the pot is constantly boiled after that, it will continue to move against this lever, and this wheel will continue to move forward because of the push of the lever!"

The scene of boiling water can be seen in every household, why don't I associate these things together!

Zhang Qixin looked at the drawings on the table, and his eyes became more and more hot.

"As long as there is enough coal and timber, then this wheel will keep spinning, and even provide a strong power to press him to the wagon, to the mill, to the water wheel!"

"It's a horse that never tires!"

Zhang Qixin can already think of the scene where he will be applied in the future, if this machine can be promoted on a large scale, then the productivity of the entire Ming Dynasty will be at least several times higher, and the people will be liberated from heavy manual labor!

This is simply a groundbreaking invention!

"How many days will you be able to get this thing for me?"

"Five days, no, three days, tomorrow Weichen can make a model of the right size tomorrow, and then install it on the carriage!"

After hearing this, Zhu Gaoyao shook his head.

"Carriage? No, no, no, it's overkill to put this kind of thing on a carriage! ”

Zhu Gaoyao opened the drawing again, revealing the drawing below.

"What about this thing!"

Judging by the scale on the drawings, this is a behemoth,

In front of it is a huge boiler with countless small wheels attached underneath, while in the rear is a wagon where coal is placed.

"It's a huge machine on wheels, how much cargo does it have to pull?"

Zhang Qixin couldn't help but sigh, if there is such a front, then the transportation of materials throughout the world will become more convenient and fast!

"If it is built according to this specification, adding dozens of carriages to the front of this locomotive is enough to pull millions of catties!"

Millions of pounds!

This is already enough to catch up with the entire baggage of the 100,000-strong army!

No, this car can even transport troops, in this case, wouldn't my Ming army be able to be mobilized in various regions anytime and anywhere!

"The gas that comes out of the boiling water is called water vapor, and this machine is called a steam engine!"

"If you want to boil the water in these boilers, you can't use ordinary wood, you have to use coal!"

"And this locomotive is called a train!"

"So, how long will it take for you to build a decent model for me?"

I am afraid that such a huge creation consumes quite a lot of metal, and the internal structure must also be quite elaborate, this kind of thing.

Zhang Qixin hesitated, because he also wanted to build this kind of steam engine and train as soon as possible, so the sooner the better, but he was afraid that there would be any mistakes in the manufacturing process, which would delay the construction period, and he promised His Majesty that he would be punished.

"Your Majesty, please give Wei Chen and the Ministry of Industry twenty days for twenty days, Wei Chen will definitely be able to build a train for Your Majesty that can run!"

Twenty days?

This is inevitably too fast, Zhu Gao's expected time is one and a half months.

In order to make such a huge locomotive row, it is necessary not only to require the strength of the metal, but also to control the precision of various structures, which can be made with current technology, but it will also be quite difficult.

Zhang Qixin, who has been working for a while after announcing the announcement, should know the current situation, how can it be done in 20 days?

"Don't be twenty days, there will be about twenty-six days before the new currency will be issued, and on the day the currency is issued, I want to see the locomotive you made, can I?"

In fact, even if Zhang Qixin said that it would take two and a half months, Zhu Gaoyi would not be angry, after all, the railway can be repaired first, and when the locomotive is manufactured, it can be directly on the road.

"Wechen will definitely not disappoint His Majesty's expectations!"

"Well, I'm just waiting for your happy results, and besides, I would like to warn you that this locomotive is quite heavy, and if you want to move or assemble it, you must first build a tower crane that can carry its weight!"

"This, Wei Chen has naturally considered it for a long time, and please don't worry about it, Your Majesty" (end of this chapter)
