After trying the trolley, it is a test track flatbed, the machining workshop is all slate, and the buried iron bar can not be done well in one or two clicks, he directly dug two shallow pits on the dirt road outside to bury the iron bar almost flat with the ground, and then pushed the large flatbed car onto the iron bar, and then began to add a cannon barrel to it.

It's easy to push a cannon barrel alone;

It's still easy to push two barrels alone;

It's still easy to push three barrels alone;

When you get to five, it's a bit difficult to push alone;

When it comes to ten, it is quite difficult to push alone, but it still pushes!

If you add it more, you have to push it with two people, but until you add twenty sticks, two people are still pushing!

This thing is so convenient, Song Yingxing decided that all the main roads of the workshop and the connecting channels between the workshops are all buried on the tracks, and this kind of cart is made of a few, so that the efficiency of the parts transfer of the entire factory has been increased by more than ten times!

The next day, he went to the emperor to report the situation, and praised the rail flatbed, and finally summed it up: The emperor is really a god.

Zhu Cijiong just wanted to roll his eyes when he heard this, he asked Song Yingxing to try to produce a rail flatbed car to let him think about steam power, this thing was not thinking in this direction at all, he thought that this rail flatbed car saved manpower and time.

What's so magical about this, it's just that the friction is different, the wooden wheels and the stone ground must have friction, and the heavier the thing, the greater the friction, the friction between the iron wheel and the iron track is almost negligible, as long as the track is not pressed and deformed, the friction will not increase, and it is natural and easy to push, rare and strange.

Seeing that this product was completely out of idea, Zhu Cijiong had to reluctantly remind: "What if you add four wheels in the middle of the flatbed truck, and then use a piston to push these four wheels?" ”

Song Yingxing's eyes lit up when he heard this, and then dimmed, and he said what he thought was the most critical question: "Your Majesty, please forgive Weichen for being presumptuous, in that case, the steam pipe can't be connected, as soon as the car moves, the steam pipe will be broken." ”

Zhu Cijiong shook his head and encouraged loudly: "If you want to invent something new, you must make bold guesses, carefully verify, you can't think according to common sense, you have to think boldly, don't be afraid to think wrong, don't be afraid to think about it." ”

When Song Yingxing heard this, he said in an incredible tone: "Your Majesty, you don't want to put the boiler on the car, such a big thing, how big a car do you have to build?" ”

Finally thinking in the right direction, Zhu Cijiong said excitedly: "How big it is, it won't be bigger than my Qianqing Palace, what does it matter if it's bigger, it's not that it can't be done." ”

Song Yingxing thought about it, it was indeed not that big, it must have been made, but the weight, he asked a little hesitantly: "Your Majesty, isn't that wheel as big as a water basin, and isn't that iron bar as thick as a thigh?" ”

That's right, Zhu Cijiong said excitedly: "Yes, yes, just make it so big, isn't it okay?" ”

Song Yingxing was stunned when he heard this, and gradually his eyes finally brightened again, and they became brighter and brighter, yes, who is not allowed to make it so big, you can make it as big as you want, as long as it can be used, he asked excitedly: "Your Majesty, can you put the coal cart and the water wheel on it?" ”

Zhu Cijiong excitedly encouraged: "Yes." ”

Song Yingxing then asked excitedly: "Your Majesty, can you build an iron house on it?" ”

Zhu Cijiong nodded affirmatively and said, "No problem." ”

Song Yingxing thought about it carefully, there was no more problem, this was equivalent to moving the whole steam-burning house, what else could there be a problem.

So he couldn't wait to say: "Your Majesty, the minister will retire first." ”

Zhu Cijiong suppressed the excitement in his heart, and solemnly instructed: "Well, you must pay attention to safety, and I will check it after it is done, and then you will start." ”

Safe? People who have never even seen a car naturally don't know that driving may cause a car accident, so Song Yingxing felt a little inexplicable when he heard the emperor's instructions, but he didn't think much about it, now his mind is full of flatbed trucks that can move by himself, how can he think about anything else.

After he returned to Wang Gong's factory, he immediately gathered dozens of students who liked to design small things, took out charcoal and large paper to draw a sketch the size of a table, and then pointed to the sketch and began to assign tasks:

Make me twelve wheels, two feet in size and about three inches thick;

A few of you will make me some steel bars, and the thickness and height will be three inches, five feet one, and twenty first;

A few of you go to the boiler building and make a new one out of the smallest boiler;

A few of you go to the machine tool to have a look, find the largest machine tool and double the size of the piston on it, and make two sets of pistons and connecting rods;

You guys make a coal car......

When all the simple things were distributed, he began to design the connecting parts in the middle, and he couldn't stop at first, and he didn't even care about the factory, and handed it over to those students who had a talent for management.

In less than ten days, all the wheels, tracks, boilers, pistons, coal cars, water wheels and other parts were all done, and Song Yingxing also made the connectors almost done, he directly transported all the parts to the site of the test firing artillery, and then buried the track on the ground and assembled it on the track.

Song Yingxing took dozens of students to change their outfits, day and night, and after five days, he forced everything to be right.

Although he was busy and dizzy, he finally didn't forget the emperor's orders, as soon as the car was loaded, he immediately ran to the palace to personally notify Zhu Cijiong to come and check.

Zhu Cijiong didn't expect him to make a steam locomotive in half a month, looking at his sunken eye sockets and stubble on his face, he knew that this product must be a waste of sleep and food. Zhu Cijiong originally wanted him to go and rest for a day before trying, but looking at his excited expression, it is estimated that he will not be able to sleep if he doesn't try today, no way, so let's try, in other words, he himself also wants to see what the first train made by Daming is like, and whether it can be run or not.

In order to dare time, Zhu Cijiong did not put on a big guard of honor, but just asked Cao Huachun to bring dozens of Jinyi guards and masters of the East Factory, and then hurried to Wang Gongchang in an ordinary eight-lift sedan chair.

When he saw Song Yingxing's masterpiece, his heart was a little confused, first of all, he must be excited, this is the first train in the Ming Dynasty and even the world, it is fake to say that he is not excited; Then he felt a little strange, Song Yingxing really built a tin house on it, it was still Chinese-style, and even the eaves, doors and windows were similar to ordinary civilian houses!

Zhu Cijiong could only comfort himself in his heart: "Okay, don't care about the appearance first, as long as you can move." ”

He whispered a few words in Cao Huachun's ear, and then walked towards the train.

At this time, the dozens of students were excitedly tasting around the locomotive, and suddenly two rows of people came up from behind, and pulled them aside very 'politely'.

Just kidding, it's the general of Jinyiwei and the fan of Dongchang who pull them, they are all muddy people who don't care about killing or burying, scolding them, looking for death!

At this time, a teenage child slowly walked over from the middle of the human wall lined up by Jinyiwei and Dongchang Fanzi, because Song Yingxing did not dare to reveal the emperor's whereabouts, so he did not tell these students that the emperor was coming, these students didn't know that this child was the emperor at first, just shrunk his head and stood aside and didn't dare to move, but a sharp-eyed student inadvertently glanced at it, the five-clawed golden dragon!

He hurriedly pulled the classmate next to him, and then immediately knelt on the ground and shouted: "The grass people see the emperor, long live my emperor, long live, long live, long live." ”

At this time, those students reacted, the five-clawed golden dragon, the dragon robe, this is the emperor! They hurriedly knelt down and shouted in unison: "The grass people see the emperor, long live my emperor, long live long live." ”

Zhu Cijiong still attaches great importance to these students, maybe there will be a few great inventors in them, he raised his hand very kindly and said: "Everyone get up, I just came to see, you are all good, I am very pleased to be able to help Chang Gung make the train so quickly." ”

Only then did everyone get up and stand there with their heads bowed, for fear of colliding with the holy car.

Zhu Cijiong came to the train and looked carefully, the boiler, steam engine and coal water car were nothing good-looking, he believed that Song Yingxing would definitely be fine, he mainly looked at the frame walking parts.

He looked down and immediately found a problem, damn it, I forgot to talk about the braking system, there was no braking problem in this ancient carriage and rickshaw, so Song Yingxing didn't think about adding brakes at all.

What to do? It must be too late to add it immediately, and it will take at least a day or two to make that thing, so he had to order Song Yingxing next to him to let people pull a few cars of sand and soil over, pour it on the first half of the track, and use a mound brake method to prevent the locomotive from rushing off the track.

Taking advantage of the time to transport sand and soil, Zhu Cijiong carefully explained to Song Yingxing what the brake system is and what to do, Song Yingxing heard that cold sweat broke out on his forehead, if such a heavy thing rushes out, I really don't know what the consequences will be.

When the first half of the track was buried in sand, Zhu Cijiong immediately said excitedly: "Chang Geng, you can start." ”

Song Yingxing couldn't wait for a long time, and after hearing this, he hurriedly saluted a few students and got on the locomotive, opened the boiler and burned it.

Soon there was a "woo-woo" sound from the locomotive, which was boiling water.

Song Yingxing looked at Zhu Cijiong, Zhu Cijiong nodded firmly, and then Song Yingxing turned around and opened the steam valve without hesitation.

"Squeak, squeak, squeak." The four groups of push wheels in the middle slowly turned, and with the rotation of the push wheels, the train finally moved, Zhu Cijiong jumped up happily, success, success, the world's first train was born!

Before he had time to celebrate, he found that the train began to accelerate, and this was okay, the track was only a hundred meters long, and this acceleration would rush out with a "whoosh", and he hurriedly shouted: "Chang Gung, hurry, quickly close the valve." ”

Song Yingxing heard the call, quickly closed the valve, and then looked nervously ahead, fortunately, the train didn't have much inertia when it just moved, and it stopped after advancing for more than ten meters on the sandy track.

As soon as the train stopped, Song Yingxing immediately opened the door and jumped down, stumbled to Zhu Cijiong, hurriedly saluted, and said excitedly: "Your Majesty, we have succeeded, we have succeeded." ”

Zhu Cijiong couldn't hide his excitement, and couldn't help laughing: "Hahaha, good, you have done a good job, all are rewarded, all are rewarded." ”
