Trimethyltoluene, which is TNT, is very safe compared to mercury thunderate, which may explode when touched, and needs to be detonated with a detonator, although it is not the most powerful fireworks under the mushroom bomb, but it is the most inexpensive thing.

"Uh... Don't think about it, although it is mentioned in the book, we can't make it. ”

Rao is Tang Sankong has a plug-in, and he can redeem this thing, but it is impossible to make this thing, because except for the name, he has not found relevant production materials in any books, and he is not a big man majoring in chemistry, and he can make smokeless gunpowder even if it is burning high incense.

"You're busy making hydrochloric acid first, and then there's this kind of fun stuff."

Everyone who studies chemistry and loves chemistry has the heart of an artist.

Dugu Yan nodded, but he didn't give up, his heart was full of fighting spirit, and he must see how powerful that trinitrotoluene is in the future!

"Guiya, and others, you will all work with this Miss Dugu Yan in the future."

"Yes, sir."

The thunder soul masters are obedient, and when the big guy speaks, they naturally agree.

"If you lack any materials, you can find me, or you can go to the building in the steel mill on the other side, he is a god craftsman, and it is still very easy to help you make some utensils. In addition, the wastewater after the reaction should not be dumped casually, and alkaline wastewater often needs to be neutralized with acid. ”

"Don't worry, I'll pay attention to this common sense."

Tang Sangang nodded, the three acids and two alkalis finally started, the chemical industry in Wuhun City finally got off to a good start, in the future, this Dugu Yan must be the chief of the Ministry of Chemical Industry, now that the steel mill and chemical plant have been established, the next step is to build a winery.

The wine culture of Douluo Continent is also relatively developed, even civilians have inferior ale wine to drink, this thing that Tang Hao has been drinking before he came out of the haze, in addition to all kinds of fruit wine, as well as the favorite wine of the upper nobles, and Tang Sangang is naturally not to produce this kind of wine for sale, the alcohol he wants, that is, ethanol.

Whether it is to make mercury thunderate as a primer, or smokeless gunpowder, or for medical treatment, it needs a very pure spirit, and Tang Sangang is most familiar with only one high-purity spirit, which is liquor.

At this point, don't Tang Sangang go to find someone in person, just hand it over to Bibi Dong's subordinates, you only need to add one more step to the original fermentation and brewing technology, that is, distillation! The fermented liquor is evaporated, the steam is passed through the condenser tube, and after cooling, it is a liquor with higher purity, and the liquor is distilled several times to obtain 95% pure alcohol.

After arranging a place for Dugu Bo and Dugu Yan, Tang Sangang came to the steelmaking plant to inspect again, and the current steelmaking plant has expanded a new mechanical processing plant next to it, not to do anything else, just to process those parts of the steam train.

Workers are digging the road surface to lay the rails, digging a channel in the ground, then leveling and compacting, laying gravel and sleepers, and laying two parallel steel rails and fixing them to the sleepers, so that the pressure can be evenly distributed as the heavy steam train travels on the tracks.

The sleepers were first made of wood, and then they were changed to concrete, and now the workers are laying wooden sleepers.

The workers bowed and saluted when they saw Tang Sanbar, and Tang Sanbar smiled and waved in response, and entered the machinery processing plant along the shallow canal that had been dug 20 centimeters deep, and saw the steam locomotive that had already taken shape at first sight.

The first steam locomotive was twenty meters long at the front, and looked like a large bucket lying horizontally, with a chimney on the top of the head, two rows of wheels at the bottom, all of which were made of steel, with two large cylinders on each side of the nose on the left and right sides, connected to the wheels by connecting rods, and the combustion chamber in front of the cab at the rear.

In total, it took nearly a year, and some of the parts that needed to be welded were completed by Huo Wu and other fire soul masters, and all the parts on the front of the car were made by Lou Gao and four apprentices, and the oversized cylinder at the front of the bike took a month.

"Looks like it's almost done."

Tang Sanbar looked up at the giant in front of him, his eyes were shining with excitement, and he admired again and again in his heart, the pitch-black front of the car was shining with a metallic luster, and he could feel a sense of oppression coming when he stood in front of it, this was the work of the first industrial revolution!

Lou Gao heard Tang Sanbar's voice, so he got out of the train cab, looking at the steam train and being extremely proud in his heart! touched his beard and said with a smile on his face,

"It's almost there, when the rails are laid, you can do a trial run test, and I'm looking forward to the moment when this big guy is running on the rails!"

He put quite a lot of emotion into this steam train, watching the molten steel flow into the mold, and then after trimming and drilling, cutting and grinding, making many parts, and installing one wheel after another connecting rods in place, the building is tall and childless, but looking at this steam train feels like this is his child!

Now that the child is born, the moment he travels, it is the time when the child grows up and starts walking, and one day, the railroad tracks will be paved all over the entire Douluo Continent, and that time is the most dazzling moment for this child.

"Good! When the test run of the train is successful, I will bring a large number of people in Wuhun City to watch and promote it for you! This is a masterpiece produced by the Blacksmiths Guild and Wuhun City! I can't guarantee what people in other places think of blacksmiths for the time being, but in Wuhun City, your status will definitely rise! ”

"Hahaha, so thank you Young Master Tang."

Lou Gao's face was full of joy, and the four apprentices and the blacksmiths they brought were also smiling, and when they heard this, they were even more energetic.

With the propaganda of the Wuhun Hall and the publication of newspapers, and the publicity of the official and non-governmental groups, it is easy for the people to improve their favor and respect for the profession of blacksmith.

"By the way, Young Master Tang, this steam train is almost finished, and that flying machine can give me a look now, right?"

Lou Gao looked up at Tang Sanbar with expectant eyes, hoping to get the reply he was looking forward to.

"Well, it doesn't hurt for you to take a look."

Tang Sanbar took out a picture and handed it to Lou Gao, Lou Gao was immediately like a treasure, but looking at the things on this picture, he was puzzled, the machine that could fly was very strange, there was a device similar to a blower blade in front of the shuttle-shaped body, a pair of wooden planks were placed horizontally in the middle of the body, and there was also a section on the tail, but it was much shorter than the one in the middle.

"This is the machine that can fly into the sky? It looks like a structure made of bird's wings. ”

"That's right! It is modeled after the body structure of a bird, and its name is airplane, which means a machine that can fly in the sky. ”

"Airplanes?"

Lou Gao looked like a picture of a bird, and muttered in his heart, the bird is much more beautiful than this thing, and the wings of the plane on this picture can't be flapped at all, how can it fly into the sky?

"How do you get this going to fly?"

Tang Sangang smiled and didn't answer, but turned around and took out an A4 piece of paper, folded it in half under Lou Gao's puzzled gaze, and then folded the corners... In a short time, a paper airplane was folded.

"I prefer to make it to you."

Pinching up the paper airplane, Tang Sanbar smiled at the paper airplane, raised his arm and wrist and threw it forward, and threw the paper airplane out, in Lou Gao's surprised gaze, the paper airplane glided in the sky and flew for more than ten seconds, like a real bird, and then slowly fell to the ground.

"See, this bird-shaped machine flies like this, in fact, if you dare to die, find some strong but light materials to make such an airplane, hang you on it, and find a fast soul master to pull the rope in front of you against the wind, you can also fly."

The human kite race is high.

Lou Gao grew his mouth, and then he realized that he had gone into a misunderstanding, and it turned out that his wings did not fanflap, but relied on an external force to push himself out. Looking at the blades in front of the fuselage on the picture, I suddenly thought that this was the external force!

"What is this blower blade thing called?" Lou Gao asked,

"That's the propeller, which relies on the fan blades to rotate to generate the wind, the fuselage in the middle, the wings on both sides, and the tail at the rear, which is the landing gear and cockpit, and the place to control this big guy."

"Nothing can be done overnight, it's still early to build an airplane, this picture will be given to you, leave you a memory."

It is not enough to make an airplane and fly into the sky with light energy, but also to be able to withstand all kinds of sudden emergencies, such as the strength of the fuselage caused by the strong wind, as well as the maneuverability of the aircraft, which are all the experience that the ancestors have summed up after countless falls, even if Tang Sanbar stands on the shoulders of giants, it is impossible to take it all together.

He can redeem a monoplane now, but what's the use of not being able to drive it, training a pilot is much more expensive and complicated than producing an airplane.

Lou Gao looked at the plane pattern on the picture, and nodded heavily, it was hopeless for him to be promoted to Title Douluo in his life, but there was still some possibility of making such a great machine to fly into the sky.

"Please, Young Master Tang, please try your best to find the raw materials for making the plane, I look at this pattern, and it feels like my dream."

Tang Sangang smiled, squatted down and patted Lou Gao's shoulder, comforting,

"This is also my dream, and it is the dream of all mankind!"
