Five days before the New Year.

"Teacher, teacher, we succeeded, we moved! We moved!" Ren Baqian was sitting in the room and heard the sound of students shouting outside the window.

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

I just adjusted the connecting rod of the steam engine and installed it on the wheels. I didn't expect it to be successful in nearly two months.

It is said that there are many people and great power, and the power of the ancient tribe is indeed great, but it is too slow to do this.

However, among so many students, there are really many people who are hindering, such as Tonglan. If they are removed, they will probably be half a month earlier.

When Ren Baqian was still in the room, he could hear the cheers of many students coming from the backyard. He walked over with his hands behind his back and saw dozens of people surrounding a huge tractor...

Well, it's really a tractor. The overall appearance is very imaginative of the tractor that Ren Baqian saw when he was a child, but it's more rough and simpler.

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

Behind it is an empty iron plate, full of coal. A man stood on it and kept adding coal to the furnace in front, and then heated the water tank from the furnace, and sent steam into the cylinder in front through the connecting pipe above.

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

As for the lower part, there are two large flywheels plus six gradually shrinking flywheels. They are no longer the earliest connections with animal tendons, but are replaced with metal connecting rods.

When Ren Baqian arrived, Du Laoliu was wearing a shirtless face and adding coal to the stove in the car.

"It's moving!" Many students cheered: "For so long, I finally succeeded in steaming cars without human power!"

Whether it is Shi Gan, the best student, or the worst-student crane, whether it is the second-generation official or the civilian student, they are all excited at this time.

Even the blacksmiths and carpenters who were transferred to help in the school were standing aside with their arms around and looking at their masterpieces! After all, this steamer also had their efforts.

"Get out of the way, get out of the way, the car is going to speed up!" Du Laoliu shouted at the crowd in front of him, adding coal to the stove without stopping, while laughing wildly with excitement.

"This is the first steam car since the creation of the world. Of course I have to start it! Hahahaha!"

"Fool!" Tonglan sat on a stone outside the crowd. When she heard Du Laoliu's laughter, she immediately curled her lips. "This thing can't turn!"

Ren Baqian, who had just arrived, heard Tonglan's muttering, and looked at Du Laoliu who was standing on the steaming car, and immediately showed a look of sympathy.

The first traffic accident of the first steamed car since the creation of the world was caused by you!

As many students moved away, the steaming car began to speed up. As the steaming car moved forward, the soil was flying behind it.

The wheels of the steamer directly pressed out two ditches on the land.

Then the speed of steaming the car began to speed up, from walking similar to a person's speed to trotting, and hitting the wall opposite!

"Hey hey? How did this thing turn? "I saw it hit the wall, Du Laoliu remembered this. He wanted to pull the reins but couldn't find them. He shouted in a hurry, and even shouted "Gao", but the steamer was still unmoved and hit the wall.

There was a sound of bricks and stones collapsed, and the steam car hit the courtyard wall and continued to move outside.

The school was on the east side of the palace and the north side of Beihong District. There were few people coming and going in this place. Only a few passers-by palace guards stopped and looked at the strange thing that bumped out of the school in surprise. They crossed the road and crashed towards the wall of the old Shiqing mansion of Dazhi!

The courtyard walls of Shiqing Mansion were made of rocks, which were much stronger than those of Xuefu. The steam car with the hard work of many students in Xuefu hit the walls of Shifu Mansion, making a huge collision sound, and a small gap was broken, but it did not break open.

The Shi Mansion suddenly seemed to stab a hornet's nest. More than a dozen strong men with big arms and round waists jumped onto the wall and stared at the murderer who dared to attack the Shi Mansion.

Du Laoliu, who was covered in dust, was immediately as if he was stared at by more than a dozen beasts, and his head was covered with cold sweat, and he smiled guiltily at everyone: "It was Shi Gan who made this."

As he spoke, he pointed at the back.

A bunch of students were running out of the gap.

"Brothers, it's an accident!" Shi Gan hurriedly came forward to explain.

"It was the steam car we made, but something unexpected happened."

When Shi Gan explained, everyone's eyes finally calmed down.

"Come back." Shi Qing waved his hand when he came outside the wall.

He looked at the steamed car that broke through the wall of his yard again curiously: "Is this the one you are busy with these days?"

"Dad!" Shi Gan said hello honestly first. Then he said a little excitedly: "This is called a steam car. It is pushed by a steam engine. It can walk without human and animal power and will not be tired."

"How many kilograms of iron does this require?" Shi Qing first focused on how many kilograms of iron this steel monster used, how many weapons can it do? How many soldiers can it arm itself?

Although the output of Damoshan iron ore is a hundred times that of the past, the price of Dayao's iron ore will drop in just two years.

However, the concepts over the past few decades have made Shi Qing unable to escape the vulgarity.

"Absolutely 2,000 kilograms." Shi Gan whispered.

After hearing this, Shi Qing was silent for a moment before saying, "You are really a big deal!"

"Master Shi, iron will no longer be restricted to Da Yao. And these things are worth not only 2,000 kilograms of iron, but even 20,000 kilograms of iron. Just like the original solar furnace, if you don't know how to use it, it will not be conspicuous at all. But if you use it correctly, you will not exchange the value of ten times or a hundred times." Ren Baqian walked from behind and smiled.

"Ren Mansion Commander!" Shi Qing nodded: "I know, but I just have an old concept and can't change it for the time being."

"I still remember what the President Ren said last time, but can this thing really be like President Ren said?"

"This is just a prototype, and we need to continue to improve." Ren Baqiandao.

"I don't understand these things, so I'm waiting to see what President Ren's performance." Shi Qing smiled at Ren Baqian, then flashed back to Shi Mansion.

Then everyone carried the steamer back for inspection, but found that the collision just now knocked a hole in the cylinder, so Du Laoliu was beaten by an old punch.

"Teacher, how can I turn around?" Someone asked Ren Baqian immediately.

"No need to turn, just let this thing run on the rails."

Then Ren Baqian found a few wooden sticks to demonstrate to everyone, and Shi Gan immediately understood. "If this is the case, the influence of the road will also be reduced, and the speed will be increased a lot."

Then he was shocked: "But how much steel should I use this?"

"You don't have to worry about this. You just need to know how much effect this thing can play. If you can set out in Lancheng and arrive in Yun Kingdom in three days, it will be worth it to consume as much iron."

"I understand!" Everyone left with excitement when they heard Ren Baqian's words.

When they made such a steamer with their own hands, everyone's enthusiasm was raised. They thought they must make the steamer that the ghost said.

Ren Baqian chuckled after seeing them leave.

Except for yourself, I'm afraid no one knows how much steel the railway needs to consume.

If they find out, they will be scared to death, and they will stop their idea of ​​building a railway.

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

Now the annual output of Damoshan Iron Mine is 2 million kilograms, only 1,000 tons. It is okay to use it to make weapons. One year's steel can create 100,000 steel knives, which directly doubles the number of Dayao's army.

It is not impossible to capture the Daxia for 200,000 iron hooves.

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

It takes at least one thousand kilometers from Lancheng to the border of Yunguo. According to the output of Damoshan iron ore, ten kilometers can be laid in a year, and more than one hundred years can be laid in such a railway.

Fortunately, Ren Baqian did not target the production of Damoshan Iron Ore at all.
