What is the symbol of the industrial age, the first thing that comes to Roland's mind is the train that runs endlessly on the railroad tracks with billowing steam. Pen "Fun" Pavilion www.biquge.info

Oil-stained cast iron cylinders, stout crankshafts and huge iron wheels, rhythmic noises and vibrations, and whistles piercing the sky – for him, the first taste of mechanical beauty began with a steam train. Compared with the mechanical systems of later generations that hide the structure under the shell, use high-precision machining to reduce tremor, and emphasize sound insulation and sound absorption measures, it undoubtedly more intuitively expresses the power and beauty of industry.

He also wanted to fill his territory with railroad tracks, so that trains could haul wagons of people and goods to and from the West, but the ideal was good, but the reality was not satisfactory - not to mention building a steam locomot, the amount of steel needed to lay the rails alone far exceeded the ingots production capacity of the North Slope furnace complex.

So the next best thing to do, a bike powered by human power became the best choice for Roland. The more flat roads in the territory, the more profitable the bicycle will be. And compared to the complex structure of the steam train, it requires almost no maintenance, and the occasional greasing of the chain is sufficient.

If he wanted to mass-produce bicycles, he could no longer let Anna make them by hand, so he first had to set up a factory and train a group of professional workers for production and vehicle assembly. Considering that Kingdom Avenue will not be completed until next spring at the earliest, the scale of the factory does not need to be too large at the beginning, and after Anna manufactures the machine tools needed for the assembly line, it is handed over to the workers to slowly familiarize themselves with the process of each link, and the production of about a dozen vehicles a month can be done. Among them, the most technical content is the chain, which needs to be stamped out by the machine, and then manually driven into the pin, connected and formed.

However, rubber parts like tires and brakes still need to be made by Soroya's ability - fortunately, this part is not a lot of work, and as long as the base mold is ready, the magic pen can quickly draw a large number of them. The same is true for bearings, can not make reliable rolling bearings, take a small section of steel casing for sliding bearings can also be used, the inner ring is covered with a smooth mirror coating, the effect is not much worse than the former.

When the bicycle was first introduced, only the aristocracy could afford this expensive means of transportation, and in order to popularize it among the masses, in addition to the hype, Roland also planned to implement an installment system to reduce the pressure of purchase as much as possible. Of course, only the lords who have obtained an identity card can apply to the town hall for this payment method.

After an afternoon of tossing and turning in the garden, Carter Lannis, worthy of the title of chief knight, mastered the art of riding first, followed by Iron Axe, and the second successfully circled the garden. Only Barov tried more than ten times without success, either crookedly on the verge of falling, or unable to move forward in a straight line. In the end, Roland had to ask Zoroya to draw a static image of him standing next to the bike with his hands on the handlebars.

"Is that all right?" asked the witch after finishing four huge posters.

"I have to add two more advertising words," Roland pondered for a moment, "and it reads: New Era Mount, I have it, and you will do it if you have it." The following is written: The bicycle factory recruits workers, the pay is good, the pay is good, and there is a chance to get a new car of your own for free. Those who have passed the primary education can register at the town hall. ”

......

After dealing with the bicycle poster, the prince returned to his office, and while there was still some time before dinner, he asked the guards to call for Kemo Stoil.

Now that a breakthrough has finally been made in the development of mercury thunderate, the development of a new generation of weapons can also be put on the agenda. There is no doubt that in the era of hot weapons, caliber represents justice, rate of fire represents freedom, and the more powerful and glorious it is, and the more turrets there are, the more equal it is...... However, an embarrassing problem is that if this development continues, the two acids obtained by laboratory methods will soon be unable to keep up with consumption.

For example, if you want to increase the rate of fire, you have to discard the black powder with a lot of residue and replace it with a smokeless fire* charge - that is, fire wool, or a mixture of fire wool and nitrocell* glycerin. The same is true for high-power explosives, it doesn't matter if trinitro*toluene (T.N.T.) can't be made, it can be replaced by nitrostarch, in addition to poor stability, the power is a few points greater than that of T.N.T.

Either of the above things, a large amount of high-concentration fuming nitric acid is required, and purification of nitric acid requires a large amount of concentrated sulfuric acid, which is not enough for the output of the laboratory. In other words, there is no way to use the industrial method to extract two acids, and even if a more efficient weapon is developed, it will fall into the predicament of running out of ammunition.

When the Chief Alchemist walked into the office, Roland spoke, "I have a new assignment for you. ”

"Say," said Camo, shrugging his shoulders, "as long as he's not at a ceremony." ”

"I need more acid, and the current output of the chemistry lab alone is no longer enough, so your new task is to design a chemical system that can produce two acids efficiently and conveniently. ”

"Chemical ...... System?" he looked confused.

"That's right, it is composed of one or several complete reaction devices, and as long as you put in raw materials, you can produce a steady stream of finished products," Roland explained the essence of industrial production simply, "I don't know much about this part, and you can only figure it out slowly on your own." ”

That being said, the prince also knew that this was a very difficult task, and that it would probably take years to study and not necessarily produce results. After all, what the other party can rely on is only some basic reaction principles and chemical equations on "Elementary Chemistry".

"I see," Kemo nodded, "and the things you mentioned are really refreshing to me. ”

"Whether you can finish it or not, the two acids are something I desperately need. "So next month I plan to expand three more laboratories by the Chishui River, and recruit qualified candidates from among the people to serve as experimenters." If you don't have time to teach them, pick a few disciples to take care of them. After all, the industrial acid process is a very long research project. ”

Probably because of the temptation of "Medium Chemistry", he agreed in one bite, "Yes, Your Highness." ”

After Camo Stoll left, Roland sighed softly.

If there is no hope for the industrial acid method, Lucia will have to follow suit to purify the acid, after all, when the big war comes, he needs more powerful weapons to win for the town.

When Roland opened the drawer, intending to eat some dried fish to relieve his boredom, he found that the drawer where the snacks were stored was empty.

Stunned, he raised his head and saw that a dried fish had been handed to his mouth.

"Are you looking for this?" smiled the blonde woman opposite.

Roland bit the dried fish and couldn't help but curl the corners of his mouth, "I thought you would stay in the fog like this for the rest of your life." ”

"That's fine, at least people can't see me, but I can still see you. The nightingale pouted.

The originally somewhat dull mood unconsciously dissipated a lot, and when he saw the familiar appearance of the other party, he couldn't help but breathe a sigh of relief, "You said before, I don't know what kind of expression to show......

"Huh?"

"Actually, it's good like this. (To be continued.) )
