After the test, the small push cart was a rail flatbed. The machining workshop was full of stone slabs, and burying iron bars could not be done in just one or two strokes. He directly dug two shallow pits on the dirt road outside to bury the iron bars about the same level as the ground, and then pushed the large flatbed cart onto the iron bars, and then began to add gun barrels to the upper.

It is easy to push a gun barrel by one person;

It is still easy to push two gun barrels by one person;

It is still easy to push three gun barrels by one person;

When it comes to the five roots, it will be a little hard to push alone;

When it reaches ten, it will be quite difficult to push alone, but it can even push!

If you add it further, two people have to push it, but it will be even more than twenty, and two people can push it!

This thing is so convenient. Song Yingxing decided to build all the main workshop roads and connecting passages between workshops on the tracks. Make several such big trucks, so that the parts transfer efficiency of the entire factory can be increased by more than ten times!

The next day, he ran to the emperor to report the situation and praised the track flatbed. Finally, he summed up: The emperor is really a god.

Zhu Cijing just wanted to roll his eyes when he heard this. He asked Song Yingxing to test-made track flatbed truck to make him think about steam power. This guy was not thinking about this direction at all. He just thought that this track flatbed truck 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. The heavier the thing, the greater the friction. The friction between the iron wheels and the rails is almost negligible. As long as the rail is not pressed and deformed, the friction will not increase. It is naturally easy to push, which is rare and strange.

Seeing that this guy was completely unthinkable, Zhu Cijing had to remind him helplessly: "What if I add four wheels in the middle of the flatbed car and then use the piston to push these four wheels?"

When Song Yingxing heard this, his eyes lit up first, and then dimmed. He said the most critical question he thought was: "Your Majesty, please forgive me for being arrogant. In that case, the steam pipe cannot be connected. When the car moves, the steam pipe will be broken."

Zhu Cijiu shook his head and encouraged loudly: "If you want to invent something new, you must be bold in guessing and be careful to verify. You cannot think according to common sense. You must think boldly, don't be afraid of thinking wrong, but afraid of not thinking."

Upon hearing this, Song Yingxing said in an incredible tone: "Master, you don't want to put the boiler in the car, what big a car do you have to build for such a big thing?"

Finally thinking about the right direction, Zhu Cijing said excitedly: "How big it is, it will never be bigger than my Qianqing Palace. What does it matter if it is bigger? It's not that I can't do it."

Song Yingxing thought about it and it was not too big. It must be done, but he asked with a little hesitation: "Master, isn't the wheel going to be as big as a basin? Wouldn't the iron bars be as thick as a thigh?"

That's right, Zhu Cijing said excitedly: "Yes, yes, just do it that big, can't it be okay?"

Song Yingxing was stunned when he heard this. Gradually, his eyes finally brightened again, and they became brighter and brighter. Yes, who is not allowed to do that, and do as big as you want. As long as you can use it, he asked excitedly: "Master, can you put that coal truck and water truck on it?"

Zhu Cijiong encouraged excitedly: "Yes."

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

Zhu Cijing nodded affirmatively and said, "No problem."

Song Yingxing thought about it carefully and there was no problem anymore. This was like moving the entire steam-burning house up, and what other problems could be there?

So he couldn't wait to say, "Your Majesty, that I'm going to take my leave first."

Zhu Cijing suppressed his inner excitement and solemnly instructed: "Well, you must pay attention to safety. After doing it, I will check it out and you can start."

Safety? People who have never seen a car before naturally don’t know that driving may cause a car accident, so Song Yingxing felt a little confused after hearing the emperor’s instructions, but he didn’t think much about it. Now his mind is full of flatbed cars that can move by himself, so he has no other thoughts.

After returning to Wanggong Factory, he immediately gathered dozens of students who liked to design small things, took out charcoal pens and big paper and drew a sketch as big as a table, and then pointed to the sketch to start assigning tasks:

You guys make me twelve wheels, first make them two feet tall and about three inches thick;

You guys make some steel bars for me, and they are three inches thick and height, five feet apart, and twenty first;

You guys go to the factory where the boiler is burning and make a new one out according to the smallest boiler;

You guys go to the machine tool to find the largest machine tool to double the size of the piston on it, and make two sets of pistons and connecting rods;

You guys make a coal truck...

After all the simple things were allocated, he began to design the connecting parts in the middle, and he couldn't stop at the beginning. He even seldom took care of the factory, and left it to the students with management talent. He basically sat there for a day, and sometimes even forgot to eat food and didn't want to sleep. He just drew and painted there, just like a demon.

There are many people and great power. In less than ten days, all the wheels, tracks, boilers, pistons, coal trucks, water trucks and other components have been made. Song Yingxing also made almost the same connection parts. He directly transported all the parts to the test-firing cannon site, and then buried the tracks on the ground and assembled them on the tracks.

Song Yingxing brought dozens of students to dress and change his clothes day and night. Five days later, he actually forced everything to face up to him.

Although he was so busy that he was dizzy, he had not forgotten the emperor's orders. As soon as the car was loaded, he immediately ran to the palace to inform Zhu Cijiu to check it out.

Zhu Cijing didn't expect that he would make a steam locomotive in half a month. Looking at his deep eye sockets and stubble on his face, you can tell that this guy must be doing it day and night. Zhu Cijing originally wanted him to take a day off before trying, but looking at his extremely excited expression, he probably wouldn't be able to sleep if he didn't try it today. There was no way, so he would try it. By the way, he also wanted to see what the first train made by Daming looked like, and it would be impossible to drive.

In order to dare to time, Zhu Cijiu did not set up a ceremonial guards, but asked Cao Huachun to bring dozens of Jinyiwei and experts from the East Factory, and then hurried to Wanggong Factory in an ordinary eight-carrying sedan chair.

When he saw Song Yingxing's masterpiece, he felt a little confused. First of all, he must be excited. This was the first train in the Ming Dynasty and even the world. It would be fake to say that he was not excited. Then he felt a little strange. Song Yingxing actually built an iron house on it, which was still Chinese. Even the eaves and doors and windows were similar to ordinary civilian houses!

Zhu Cijing could only comfort himself in his heart: "Okay, don't worry about the appearance first, just be able to 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 surrounding the locomotive and excitedly commenting. Suddenly, two rows of people came up from behind and pulled them aside very politely. The students were about to get angry, and they could see the person who pulled them, so they immediately covered their mouths and dared not speak.

Just kidding them, the generals of the Jinyiwei and the Dongchang man were all the people who were killed or buried, scolding them and seeking death!

At this time, a teenage child slowly walked over from the middle of the wall of the Jinyiwei and Dongchang. Since Song Yingxing did not dare to reveal the whereabouts of the emperor, he did not tell these students that the emperor was coming. These students did not know that the child was the emperor at first, but just stood aside with his head shrank and did not dare to move. However, a sharp-eyed student glanced at the five-clawed golden dragon inadvertently!

He quickly pulled the classmate next to him and immediately knelt on the ground and shouted: "Long live my emperor, let me see you."

Only then did the students realize that the five-clawed golden dragon and dragon robe, this is the emperor! They quickly knelt down and shouted in unison: "Grass people meet the emperor, long live my emperor."

Zhu Cijiu still attaches great importance to these students. Maybe there will be several great inventors. He raised his hand kindly and said, "Everyone, I'm just here to see. You are all good. I'm very pleased to help Chang Geng make the train so quickly."

Then everyone got up with great gratitude, bowed their heads and stood there, fearing that they would run into the sage.

Zhu Cijiu came to the train and looked carefully. There was nothing good about the boiler, steam engine and coal water truck. He believed that Song Yingxing would definitely have no problem. He mainly looked at the frame walking parts.

He looked down and immediately found a problem. Damn, I forgot to mention the brake system. There was no brake problem in ancient carriages and rickshaws, so Song Yingxing never thought about adding brakes.

What to do? It must be too late to add immediately. It will take at least one or two days to make the thing. He had to instruct Song Yingxing next to him to pull a few trucks of sand and soil over, and pour it into the first half of the track, and use a dirt-stack brake method to prevent the motorcycle from rushing out of the track.

Taking advantage of the time of transporting sand and soil, Zhu Cijiu carefully explained to Song Yingxing what the brake system was and how to do it. Song Yingxing felt cold sweat on his forehead when he heard this. If such a heavy thing rushed out, I really don’t know what the consequences would be.

After the first half of the track was buried by sand, Zhu Cijing immediately said excitedly: "Chang Geng, you can start."

Song Yingxing had been impatient. After hearing this, he greeted several students and got on the motorcycle, turned on the boiler and started to burn.

Soon, a "whip" sounded on the motorcycle, and the water was boiling.

Song Yingxing looked at Zhu Cijing, Zhu Cijing firmly pointed his head, and then Song Yingxing turned around and opened the steam valve without hesitation.

"Squeak, squeak, squeak." The four groups of pushing wheels in the middle slowly turned. As the pushing wheels rotated, the train finally moved. Zhu Cijiu jumped up happily, succeeded, and the world's first train was born!

Before he could celebrate, he found that the train was starting to accelerate. It was not bad. The track was only 100 meters long in total. This acceleration would rush out "swoosh". He quickly shouted: "Chang Geng, hurry, close the valve quickly."

When Song Yingxing heard the sound of the call, he quickly turned off the valve and looked ahead nervously. Fortunately, the train had not had much inertia as soon as it moved, so he walked about ten meters on the track buried by sand and soil before stopping.

As soon as the train stopped, Song Yingxing immediately opened the door and jumped down, stumbled to Zhu Cijing, bowed hurriedly, and said excitedly: "Master, we have succeeded, we have succeeded."

Zhu Cijing couldn't hide his excitement and couldn't help laughing: "Hahaha, okay, you did a good job, you all have rewards, all of them are rewarded."
Chapter completed!
