Five days before the New Year.

"Teacher, teacher, we succeeded, moved!" Ren Baqian sat in the room when he heard the sound of students shouting outside the window.

Ren Baqian closed the books in his hand, he had been paying attention to the progress of these students, and he had thought that it would be earlier.

I just adjusted the connecting rod of the steam engine and installed the wheels, but I didn't expect it to take nearly two months to succeed.

It is said that there is great strength in numbers, and the strength of the ancient people is indeed very large, but it is okay to be slow in this matter.

However, among so many students, there are really a lot of hindrances, such as Tonglan, if they are eliminated, it is estimated that it will be half a month earlier.

Ren Baqian was still in the room when he heard the cheers of many students coming from the backyard, and he walked over with his hands behind his back, only to see dozens of people surrounding a huge tractor......

Well, it's really a tractor, and the overall appearance is very imaginary from the tractor that Ren Baqian saw when he was a child, but it's rougher and more rudimentary.

The cylindrical steam engine is at the front, and there is an exhaust pipe on it.

Behind is an empty iron plate, piled with coal, on which a man stands and continuously adds coal to the furnace in front, which then heats the water tank and feeds the steam into the front cylinder through the connecting pipe above.

At the same time, the students also took advantage of the characteristics of water and steam conversion to make a deflector under the cylinder, which can send the cooled water from the lower deflector back to the tank.

As for the bottom, there are two large flywheels and six gradually shrinking flywheels, which are no longer connected by animal tendons at the earliest, but replaced by metal connecting rods.

When Ren 8000 arrived, Du Lao Liu was adding coal to the furnace in the car with a bare face.

"It's moving!" Many students cheered: "After so long, I finally succeeded in making a steam car that can be moved without human labor!"

Whether it is Shi Kang, who is the best learner, or the crane tail with the worst grades, whether it is the second generation of officials or civilian students, they are all excited at this time.

Even the blacksmiths and carpenters who had been transferred by Tong Zhenye to help in the academy were standing with their arms crossed and looking at their masterpieces! After all, this steam car also had their hearts and minds inside.

"Get out of the way, get out of the way, the car is going to speed up!" Du Lao Liu shouted to the crowd in front of him, adding coal to the stove without stopping at all, and at the same time laughing excitedly.

"This is the first steam car since the beginning of the world, of course I have to start it!hahahaha!"

"Fool!" Tonglan sat on a stone outside the crowd, and when she heard Du Laoliu's laughter, she immediately pouted. "This thing can't be turned!"

Ren Baqian, who had just come over, heard Tonglan's muttering, and then looked at Du Lao Liu, who was standing on the steam car, and suddenly showed a sympathetic look.

You were the one who caused the first traffic accident of the first steam car since the beginning of the world!

As many of the students got out of the way, the speed of the steam car began to pick up, and as the steam car moved forward, dirt flew behind it.

The wheels of the steam car pressed two furrows directly into the earth.

Then the speed of the steam car began to increase, from the speed of a person walking to the speed of a person trotting, and slammed headlong into the opposite courtyard wall!

"Hey, hey, how can this thing turn around?" Seeing that it hit the wall, Du Lao Liu remembered this, and wanted to pull the reins but couldn't find it, so he hurriedly shouted, and even shouted "driving" in a hurry, but the steam car was still unmoved, and hit the courtyard wall.

There was a sound of falling masonry, and the steam cart crashed past the courtyard wall and continued outside.

The school is in the east of the palace, the north of Beihong District, this place is rarely visited, only a few passing palace guards stopped and looked at the strange thing that crashed out of the school with a surprised face, crossed the road, and crashed towards the courtyard wall of the mansion of the old Shi Qing!

The courtyard wall of Shiqing's mansion was all made of rock, which was much stronger than the wall of the school, and the steam car with the hard work of many students of the academy crashed into the wall of the Shifu courtyard with a huge crashing sound, and hit a small gap, but it did not crash open.

Shifu suddenly stabbed a hornet's nest, and more than a dozen strong men with big shoulders and round waists jumped on the wall and stared at the murderers who dared to attack Shifu.

The gray-faced Du Lao Liu suddenly seemed to be being targeted by more than a dozen fierce beasts, cold sweat broke out on the top of his head, and he smiled at everyone: "It was Shi Dare who made this." ”

As he spoke, he pointed behind him.

A bunch of students were running out of the gap.

"Brothers, it's an accident!" Shi Dang hurriedly greeted and explained.

"It was a steam car we made, but something happened. ”

Youshi dared to explain, and everyone's eyes finally eased.

"Come back. Shi Qing didn't know when he came to the wall and waved his hand.

He looked curiously at the steam car that crashed through the wall of his yard: "This is the one you are busy with these days?"

"Dad!" Shi Dang first said hello honestly. Then he said with a little excitement: "This is called a steam car, which is propelled by a steam engine, and it can walk without human and animal power, and it will not be tired." ”

"How many catties of iron does this need!" Shi Qing's first concern was how many catties of iron this steel monster used, how many weapons could this make, and how many soldiers could be armed?

Although the output of Damoshan iron ore has been 100 times that of before, as long as it takes another two years, the price of iron ore in Dayao will be able to fall.

However, the concept of decades has made Shi Qing not exempt from vulgarity.

"Almost 2,000 pounds. Shi Dang whispered.

Shi Qing was silent for a moment after hearing this, and then said, "You guys are really generous!"

"Lord Shi, Tie will no longer restrict Da Yao. And these things are worth 2,000 catties of iron, even 20,000 catties of iron. Just like the original solar stove, if you don't know how to use it, it won't be conspicuous at all. But if it is used in the right place, it will not be exchanged for ten times and a hundred times the value. Ren Baqian came from behind and said with a smile.

"Governor Ren!" Shi Qingchao nodded: "The old man knows, it's just an old concept, and he can't change it for a while." ”

"The old man still remembers what the governor said last time, but can this thing really be as the governor said?"

"This is just a prototype and we have to continue to improve. "Ren 8000.

The old man didn't understand these things, so he waited to see the performance of the governor. Shi Qing smiled at Ren Baqian, and returned to Shifu in a flash.

Then everyone carried the steam car back to check, and it turned out that Fang Cai's collision knocked the cylinder out of a hole, and Du Lao Liu was beaten by the old punch.

"Teacher, how can this be turned?" someone immediately asked Ren Baqian.

"There's no need to steer, just make this thing run on rails. ”

Then Ren Baqian found a few wooden sticks to demonstrate to everyone, and Shi Kang immediately understood. "If that's the case, the impact of the road is reduced and the speed can be increased a lot. ”

Then he said, "But how much steel does it take?"

"You don't have to worry about that. You just need to know how much of a role this thing can do. If you can set off from Lancheng and arrive in Cloud Country in three days, then it will be worth it to consume as much iron as possible. ”

"Understood!" everyone heard Ren Baqian's words and immediately left with excitement.

When they made such a steam car with their own hands, everyone's enthusiasm was raised. I thought I had to make the kind of steam car that the ghost said.

After Ren Baqian saw them leave, he chuckled.

I'm afraid that no one knows how much steel the railway needs to consume except himself.

If they found out, they would be scared to death, and they would desperately stop their idea of building a railway.

One meter of rail costs 100 kilograms of steel, and one kilometer requires 100 tons of steel.

Now the annual output of Damoshan Iron Mine is 2 million catties, but it is only 1,000 tons. It can be used to make weapons, and a year's worth of steel can make 100,000 steel knives, which directly doubles the number of Da Yao's army.

200,000 iron hooves, even if it is a great summer, it is not impossible.

But if you want to build a railway, don't think about it.

From Lancheng to the border of Yunguo, it will be at least more than 1,000 kilometers. According to the output of the Damoshan iron mine, it can only be laid ten kilometers a year, and it will take more than 100 years to lay such a railway.

Fortunately, Ren Baqian didn't aim at the output of the Damoshan Iron Mine.

Iron ore, Yunguo has.
