The blue sky, without a trace of clouds, a goshawk curiously hovered over the Queerghada Mountain and the Tien Shan Mountains, with its keen eyes, it could clearly see the people who were busy going back and forth on the ground, but it didn't understand what these people were doing around a black behemoth, in front of this black big man, there were two straight lines that stretched for a long time.

After looking at it for a while, the goshawk felt very bored, these humans were really strange, the good weather did not go to find food as soon as possible, but was useless to work blindly, so the goshawk flapped its wings and flew into the distance.

And Abu was next to the behemoth, constantly busy up and down, Zhang Liang was next to Bai Boda, and asked in a low voice: "Uncle Bai, you said that Mr. Abu can make such a big guy?" Just to build this so-called locomotive, it cost a hill of steel, and it is estimated that it will not be able to pull it away with more than a dozen large carriages. Is it a bit whimsical to be able to just boil some water to make it run? ”

Bai Boda's hand was a little itchy, and he couldn't help but want to knock twice on Zhang Liang's head, he has always had the habit of knocking on other people's heads, especially on his own son.

In the end, he endured it, shook his hand, and taught Zhang Liang a lesson: "Boy of the Zhang family, tell me, from the beginning to the present, what Mr. Abu has done is unreliable?" What's not going to work?

Don't always speculate about Mr. Abu with your simple head, there are so many things you don't understand? For example, could you have imagined that steelmaking would be as easy as it is now? ”

"Well, that's ......" Zhang Liang was speechless for a moment, and said with a smile, "Actually, I also have a lot of admiration for Mr. Abu, I'm just curious about the principle." ”

"The principle is actually very simple, and when Mr. Fang and Abu discussed it last time, I happened to listen to it next to me. To put it bluntly, this is the same as our use of the waterfall to blow the wind, using the drop of the waterfall to drive the water drain to rotate, and then drive the connecting rod to reciprocate. ”

"I know this, but what's the use of boiling some hot water with coal, such a big piece of iron can't be compared to a bellows."

"Mr. Abu said that when the water boils, it turns into steam, and the steam pushes the connecting rod, and you see we also made a double-acting connecting rod, which will reciprocate under the action of steam, so that it can drive the iron wheel to move.

In fact, the steam in the boiler will expand when it boils to a certain extent, and when it expands to a certain extent, it produces even more force than a waterfall.

Mr. Abu also said that if there was an accidental explosion, the consequences would be really unimaginable, so he only dared to start this step after we had made a large amount of high-quality steel.

Don't look at Mr. Abu's young age, he is quite cautious in doing things, sometimes more thoughtful than those of us who are old. Young man, study hard, do your own work first, and then talk about it, it will start soon, but don't make any mistakes. ”

Zhang Liang agreed, and carefully checked the division of labor in his hands according to the division of labor and procedures in advance.

This is a nearly 500-meter railroad track, after all, it is just a test, you don't need to invest too much in the early stage, and it is not too late to wait for the front of the locomotive to be perfected, and then slowly extended.

Whether it is the stones for laying the rails or the sleepers, they are all built according to the designs of later generations, and sometimes Abu feels that he has picked up too many ready-made cheap, and every improvement in these processes has been achieved through the hard work of wise people in the past.

For example, when the steam engine was first invented, the noise and vibration were too strong, causing the people in the car to be disgraced and foaming at the mouth when they were bumped.

Later, Stephenson added shock-absorbing springs under the carriage, replaced pig iron with wrought iron as the material used to make the rails, and added small stones under the sleepers to cushion and counteract the vibration of the vehicle.

Each of the above improvement measures requires long-term practice and accumulation, and now I have directly put it in place in one step, avoiding a lot of potential problems and saving a lot of trouble.

As long as there are no gaps in the manufacturing process and workflow, then at least there is no problem in principle, after all, in later generations, steam locomotives have been proven by a lot of practice.

When Abu got out of the front of the car, Fang Zhengyi also walked over and asked Abu if he could start. Born into a family, Founder was amazed by the design of the drawings and the manufacturing that followed, but his prowess was fully demonstrated in the manufacture of water drains and blowers.

Abu nodded and said that all the steps had been checked and there was no problem, and Fang Zheng's face was full of excitement for a moment, this may be the biggest achievement and dream of his life, and he will soon come true.

He patted Abu on the shoulder vigorously, turned to the front of the car, opened the door, and sat in the driver's seat inside.

Abu put a whistle to his mouth, waved the small flag in his hand a few times, and blew the whistle in his mouth. The people around the car scattered one after another, retreating a certain distance, and the staff on the car took action, some delivered coal, some blew wind, and some were responsible for conveying orders.

Smoke billowed up from the chimney, and the hot water, which had already been boiled, began to boil again, like waves rolling in the boiler.

Fang Zhengyi stared closely at the graduated hands under the glass cover in front of him, and his heart was surging.

He designed the steam engine himself under the guidance of Abu, and he knew every detail of the car well, and at the same time his admiration for Abu was overwhelming.

In the past, their family was able to make good use of water power, but they all used the energy generated by the difference in water to operate, and they never thought that power could be generated by heating water and steam, and Mr. Abu's great idea could be verified immediately.

Fang Huanting stood next to Meng Lu, her palms were covered with sweat, she had been dependent on her father since she was a child, and if she said that she was not worried, it would be a lie.

She had heard that her father was going to test drive this steam engine before, but Fang Huanting didn't take it to heart, she always thought that her father was joking, but when she had dinner last night, her father didn't even drink a little wine, he said that he was going to drive a steam locomotive tomorrow, and it was easy to make mistakes when drinking.

So Fang Huanting, who was full of worries, persuaded her father if she could let someone else go, and her heart was full of vigilance for such a big guy as a steam engine.

Fang Zhengyi refused, saying that this car was designed by him himself, and no one was more familiar with the principles and operation than him.

The opportunity to realize the dream of such a great genius was in front of him, and if he hadn't driven it himself for the first time, he would have regretted it for the rest of his life, and his fascination and fanaticism for technology had taken over his entire brain.

The two children of their own standing next to Fang Huanting did not have a little psychological burden, chattering and laughing, and showing off to other children, saying that the big iron man was sitting on top of their grandfather.

and ran back with her face up, confirming the correctness of the matter to her mother, Fang Huanting could only smile and nod yes at her own children.

Meng Lu saw Fang Huanting's worries, so she comforted her and said that this was designed and manufactured by Mr. Fang himself, and if he was not sure, it would be impossible for him to go up and operate it himself.

In addition, with Mr. Abu's person, he has never been unsuccessful in doing things, you see the fertilizer, glass, soap, perfume, etc. we make, and there is not a single thing that has gone wrong so far, so you can relax. Fang Huanting smiled at Meng Lu, and her heart was indeed a lot more relaxed.

At this moment, the behemoth in front of him moved, and Fang Zheng, who was sitting in the front of the car, looked at the pointer and knew that the pressure at this time had reached the starting standard, so he slowly lowered the lever.

Instantly, compressed steam erupts from the open valve, hits the pistons, squeezes the connecting rods, and drives the wheels. There was a cacophony of metal grinding, and the whole front of the car vibrated as it slowly began to move along the laid rails.

The earth-shattering cheers rang out, and everyone's faces were filled with smiles of wonder and joy, this was definitely a great victory!

Fang Huanting and the children around her were full of pride on their faces, and Abu looked at the steam locomotive that was gradually moving away, and his heart was also full of relief and excitement, the first steam locomotive of this era was born from here.

Before the end of November this year, in just a few months, the railroad tracks had been paved to the valley valley mouth, and the number of carriages hanging behind it had increased to more than ten cars, and all kinds of raw materials and materials piled up at the valley mouth were swept away.

The excited people couldn't help but ask Abu for instructions, in order to improve the efficiency of transportation, should the railroad tracks be laid directly in front of Abu's hotel? Otherwise, the last stretch from the Abu Inn to the valley mouth will still greatly limit the efficiency of the round-trip transportation.

Abu thought about this question repeatedly, and then through the measurement of the hole cards in his hand, and after a heated discussion with everyone, finally decided to do it!

In the middle of March of the second year of Tianbao, passing by the business travelers of Abu Hotel, they saw many people working in full swing, and they used stones to make the foundation under their feet, and the square wood was evenly placed on it, and there were two long steel ingots on the wood, which were winding like a giant snake, and extended to the distance.

Every traveler can't help but have the same thought in their minds: What is this to do? This is definitely a big deal! But it's too loser, wasting so much steel, how many iron tools or weapons can be made?

At the beginning of April of the second year of Tempo, while all the travelers of the Abu Inn were drinking and eating or resting in bed, they were alarmed by the shaking of the earth and the distant rumbling, and they ran out of their rooms to see what had happened.

In the distance, a black iron dragon, emitting smoke, rushed towards him along the paved railroad tracks.

Everyone couldn't believe their eyes, what kind of monster was this?

Just when the people were shocked and ready to flee, the waiter at the Abu Hotel stopped them and said calmly that they should not be afraid, this is called a steam locomotive, which is used to pull goods.

As the steam locomotive slowed down, the dragon finally stopped not far from the Abu Inn.

This is the epoch-making product of the steam locomotive, which has made its public appearance in front of the world, and it is also the first time that the people of the valley led by Abu have publicly revealed their scientific and technological strength to the world, and they are shocked and hideous.
