[PS: According to Xinhua News Agency, at 12 o'clock at noon today, the author's head and tofu came to a close contact, and in the end the tofu was still intact, the author's head bloomed, and he was sent to the hospital for rescue to no avail, and he lived forever in his own heart. 】

During the Ming Dynasty, iron-making technology was already very developed, and its formula was very close to the iron-making standards of later generations.

This is also why Fan Jinyan asked Luo Wei to call his father just to change the molten iron to mature molten iron.

Because the molten pig iron only goes to the biggest impurities, but there are still a lot of various impurities in it, it is okay to build some farm tools, but it is a little unrealistic to build sword machinery. Wrought iron is made by repeated melting and repeated degrading, and swords in the army are generally made of this kind of molten iron. There is also a kind called 100 steel, after each dequaintion, it has to be beaten repeatedly, and finally the purest ironclad is achieved, and the Tang knife is made of this kind of steel.

A few days later, the black boy Luo Wei personally went to the Hou Mansion to invite Fan Jinyan to go to the experiment.

After Fan Jinyan arrived, he saw that the teacup was still the same teacup, but because the quality had improved, the surface was much smoother, and the eye color was lighter.

But for the sake of safety, after adding water to the fire and adding coal, everyone still hid far away and waited for the result.

This time, Luo Wei's father, Luo Blacksmith, also came, and one of the virtues of the two elders was as black as carbon, and those who didn't know thought they were refugees from Africa.

This time, after waiting for more than two hours, the steam engine did not explode until all the baskets of coal burned out.

After the iron wall cooled down, everyone carefully checked it up and down several times, but they didn't find anything wrong.

Only one problem can be proven, and the experiment was successful.

At this time, everyone was happy and cheered loudly again.

Fan Jinyan waited for the students to cheer enough, and then sighed: "You have finally proved your ability with practice, Ben Hou is very relieved, very happy, Luo Wei obeyed orders." ”

Obviously, this is about rewarding meritorious deeds.

Luo Wei grinned his white teeth and knelt down with a smile: "The student is here." ”

Regarding Xiao Young's mentality, Fan Jinyan has also experienced it, and he is not dissatisfied, and continued: "The steam engine experiment was successful, Luo Wei contributed a lot, and he is now rewarded with a thousand taels of silver." ”

"Master Xie." A thousand taels of silver, Luo Wei had never seen so much silver in his life, and tears of excitement suddenly flowed out.

The other students also rewarded each with five hundred taels of silver, and asked Luo Wei to take the other students to start studying the locomotive drawing and make it as soon as possible.

Of course, Blacksmith Luo was also rewarded with one hundred taels of silver by Fan Jinyan, and told him to use better wrought iron for future steam engines to ensure that there would be no accidents.

The hardest part is successful, and the locomotive is much simpler, and it can't just be a transmission car.

Two months later, the construction of the steam engine locomotive was officially completed, due to the problem of welding technology, the front of the locomotive did not look beautiful, but Fan Jinyan did not want beauty, but practicality.

In order to be able to do a good job in the experiment, a serpentine railway track several kilometers long was specially laid at the test site

In order to witness this historic moment, hundreds of people gathered at the test site to see with their own eyes how this iron lump ran on the ground.

On the hill next to the test site, a simple stand was specially set up, and all the officials of various ministries and their families came to watch the ceremony.

Liang Xiangru, who is about to give birth, is also accompanied by Han Yaxuan and Sophie to witness another miracle of the world.

Fan Jinyan did not rush to wait in the stands, but watched the students do the final debugging work in the test field.

"Lowe, do you have the confidence to succeed at the first time?" Fan Jinyan asked the black boy next to him who kept rubbing his hands, obviously very nervous.

"Ahh Luo Wei's mind was on Fan Jinyan's body at all, and after hearing the words of the Hou Ye next to him, he was stunned for a long time before he replied with some lack of confidence: "Because it should be, maybe, it may be fine!" ”

When the words fell, he was hit by Fan Jinyan and fried chestnuts, only to see him say slightly angrily: "You kid, no matter what you do, you must have confidence in yourself, you don't even have confidence in such a simple thing, how can Ben Hou entrust you with big things in the future." ”

There's something in that!

Luo Wei can get Fan Jinyan's favor, naturally he is not stupid.

Obviously, he heard that Hou Ye wanted to reuse himself, so he straightened his chest and tried his best to put on a confident appearance, "Hou Ye rest assured, if you don't succeed, the student will become benevolent." ”

The words fell, and Fan Jinyan was hit with a fried chestnut.

smiled and scolded: "Lao Tzu uses you to become benevolent? It's better to keep your life and run an errand for Lao Tzu! ”

After the train was successful, Fan Jinyan did have important things to do with these young men.

As for what is important, only Fan Jinyan knows it in his heart so far.

After the students finished debugging, they came to Fan Jinyan and said, "Master Hou, the Nanzhou College has been debugged and can start the experiment." ”

In order to commemorate the achievements of these students, Fan Jinyan named the first locomotive Nanzhou College. The implication is that the first train came from the students of Nanzhou College.

This is the time to establish Luo Wei's prestige, Fan Jinyan did not mean to steal the limelight, but said to Luo Wei: "It's better for you to come!" You are its creator. ”

Luo Wei knew in his heart that he didn't say anything more, but after giving Fan Jinyan a big salute, he got up and walked to the front of the train and shouted: "Start the Nanzhou Academy"

When the words fell, a strong man with dark skin and a short dress on the train threw the torch in his hand into the boiler, and the wood that had already been poured tung oil 'boom', and the fire was blazing. After that, the strong man used a shovel to feed the coal beside him into the boiler, so that the fire inside burned more and more.

Soon, there was a clear 'crunch', and the gears of the steam engine, which had been connected to the gears of the train, began to rotate slowly, and at the same time, the main gears of the locomotive began to rotate slowly.

As the gears of the steam engine got faster and faster, the main gears also increased their speed, and finally there was a louder 'crunch' sound, and the front of the car began to move.

With the operation of the workers in the cab, the speed of the front of the car became faster and faster, and soon it finished a lap of rails and stopped at the starting point.

How can I make it enjoyable to watch the excitement after only running a lap, and with the shouts of the people, the train starts again.

One lap

Two laps

It wasn't until the coal burned out that the train slowly stopped, and the lively people went home unsatisfied.

For a while, the moving iron box became a topic that the people of Qiongzhou talked about after dinner.

Only a few people, after hearing the conversation of the common people, scoffed and their faces were full of disdain. (To be continued.) )
