After the gas valve opened, there was a stabbing hiss, the white mist rolled, and the whistle that had just been pulled resounded in the sky of this plain under the high mountains. Pen ~ fun ~ pavilion www.biquge.info

Moving the brake valve, as the various positions on the machinery snapped, a sound of gold and iron clashing sounded.

The body shook again, and it took nearly thirty minutes from ignition to the start of the vehicle, which is also the disadvantage of the steam engine, because it takes a process to heat the water to a large amount of boiling and form water vapor, especially such a large pot of water.

When the wheels of the steam locomotive began to move slowly and forward, many people had strange expressions on their faces, this big guy, can he walk by himself without being pulled? Seems a little slower?

Questioning voices, curious looks, and surprised expressions appeared on everyone's faces. But because the track is so short, the speed of the vehicles simply cannot be combined.

The vehicle had just slid a few dozen meters away, Yao Ran pulled the brake valve, and then the vehicle slowly moved forward for about ten meters, and then the car stopped steadily.

And Yao Huo in the car, as well as Xiaolong, were full of excitement, because this was the first car that could walk on its own without any external force, and the people who made him were all feeling the power of steel in this car at the moment.

Although this power is still very weak. But Yao Huo and Xiaolong's firm gaze could see that they were not disappointed, after all, both of them were high-achieving students, especially Yao Huo.

Because the steam engine is made by Yao Huo, the working state of the steam engine is a gradual process from ignition to operation, and when it just starts, it is the slowest time for the whole equipment to run.

If you can run to the speed just now, then if you reach the peak speed, it will be faster than the alpaca, and according to the teacher Yao Ran, this car can drive at least 10 fully loaded cargo boxes.

What's that concept? Ten huge cargo boxes, more than the Kodo beasts carried, much more. You don't have to go to great lengths to find him fresh fruits to eat. As long as there are those black stones dug out of the mountains, he can do his work. What a deal.

Of course, it took a lot of effort to produce it, and it took more than two months. But it won't be so slow in the future.

The molds for all the parts are ready-made, as long as the molds are cast and the installation begins, and now there is another chassis quietly waiting in place.

Yao Ran is also full of emotion at this moment, the weapon of the Enlightenment era, the origin of scientific and technological civilization, has now appeared in his own territory.

The iron wheel of the steam engine will drive the entire Yao tribe to roll forward. Whether you can live a happy life really depends on this big iron bump.

Because of the foreign copper, aluminum, and tin minerals, materials, and a large number of people, they will be sent far and continuously under the drive of these two railroad tracks, and in front of Yao Ran, they will finally be used by Yao Ran.

Yao Ran moved the wrench to change the direction of the pushing rod on the moving wheel under the locomotive of this steam engine, then took a few steps back, and then the opening was so good that Yao Huo opened the air valve and let him drive back.

Then, as Yao Huo retracted, the vehicle once again emitted various sounds of its metal internal impact, and then the entire steam locomotive began to move.

Yao Ran ran a few steps and rushed to the operation room with an iron ladder. The board in my hand is rubbed with black grease, of course, this grease is to make the equipment play some protective role when it is running.

Because high-speed operation of bearing connecting rods and other materials will cause the entire equipment to overheat

Lubricating oil plays some role in heat insulation and lubrication, so as to effectively protect it.

And at this moment, Yao Ran's hands, wrenches, and face were covered with black oil. Hou Yun hurriedly took out his handkerchief to wipe it for Yao Ran, but Yao Ran reached out and stopped it.

"Don't wipe it, I'll show the big guy later, this kind of encouragement will make our next car better."

Yao Ran is right, there is no encouragement, there is no encouragement, the way to cheer is better than fighting side by side. Endure hardships together.

So Yao Ran is well aware of the truth, and doing things like shows, Yao Ran has seen all kinds of shows as early as when he was young. There are some people you know he's putting on, but they're not offended.

And some people obviously didn't put on a show, but they set themselves up. Doing the facts is like putting on a show, and in the end, it doesn't end up being good inside and out.

At this moment, Yao Ran sat on the steam locomotive and watched the locomotive slowly drive into the position just now. As soon as he stood firm, Yao Ran jumped out of the car and looked at the clansmen in front of him, as well as workers from all over the country.

Yao Ran said, "Today, our steam locomotive has been successfully assembled, and just now our three main creators have also personally tested it. It's not a long way off, but it's a big step for us. This innovative achievement is no less than the introduction of the steam engine into our factory. ”

Although Yao Ran was embarrassed, his spirit became like a stimulant after he had just experienced the steam locomotive he developed, "In the future, our railways will extend in all directions and connect to every inch of our land." ”

"We can eat the aquatic products that Canglong City brought up this morning in Yaozhai, and we can use the ice that was shoveled down at dawn in the Great Snow Mountain in Canglong City." As Yao Ran spoke, everyone's expressions became even more surprised. There is also a drunken yearning.

Because many of the men present had followed Yao Ran to fight in the Great Snow Mountain and Canglong City, and there were also people who had been to and fought in both places, and the beautiful scenery and food of those places were unforgettable.

And at this moment, Yao Ran was once again aroused, if you don't have to travel a long distance to enjoy those things at home, it is really a beautiful thing. Because the golden nest and the silver nest are not as good as the grass nest in their own home.

No matter how beautiful the scenery outside, I don't feel comfortable staying in my familiar environment. Enjoy the comfort and relaxation after a busy day.

Therefore, the point that Yao Ran found and the ten rings hit the needs of everyone present, and Yao Huo was convinced in his heart, the teacher is the teacher, it is really difficult to match it. I don't know when I'll have the ability to be like a teacher.

"In the future, we will produce more steam locomotives, and in order to let our children and grandchildren live a happier life than us, we will turn ourselves into giants, so that our children and grandchildren will stand on our shoulders and see farther places."

Yao Ran's last concluding statement will become a famous aphorism in the future, and Yao Ran can imagine it. And it's a kind of unassuming show.

"So today we named our first steam locomotive, 'Dongfeng'!" The first steam locomotive had its own name. Dongfeng!
