What was the symbol of the industrial age, Roland's first thought was to braving the rolling steam and roiling the train on the tracks.

The oily cast-iron cylinders, the stout crankshafts and the huge iron wheels, the rhythmic noise and vibration, and the sound of the whistle that cut the void—for him, the beauty of the first-time machine began with the steam train.Compared with the mechanical systems that hide the structure under the shell, use high-precision processing to reduce tremors, and emphasize sound insulation and sound absorption measures, it undoubtedly shows the industrial force and beauty more intuitively.

He also wanted to spread the tracks in the territory, allowing the train towing a carriage of people and goods to and from the west, but the ideal was good, but the reality was not satisfactory - not to mention the manufacture of a steam train, just the large amount of steel needed to lay the rails far beyond the ingot production capacity of the kilns on the north slope.

So secondly, a human-powered bicycle became Roland's best choice.The more flat roads in the Territory are built, the greater the revenue from bicycles.And relatively complex steam train, it almost no maintenance, occasionally anoint the chain.

If you plan to mass-produce bicycles, you can no longer let Anna handmade, so he first has to build a factory to train a group of professional workers for production and vehicle assembly.Considering that the Kingdom Avenue will not be completed until next spring at the earliest, the scale of the factory at the beginning does not need to be too large, and after Anna makes the machine tools required for the assembly line, it will be handed over to the workers to slowly familiarize themselves with the process and produce more than a dozen in a month.Among them, the highest technical content is the chain, which needs to be stamped out by the machine, and then manually enter the pin, and connect the molding.

But rubber parts like tires and brakes still need to be made with Soroya’s abilities—good news that this part doesn’t work much, and as long as the base mold is ready, the magic pen can draw a lot of it.Bearings are the same, can not make reliable performance of rolling bearings, take a small strip of steel casing for sliding bearings can also be used, the inner ring covers the smooth mirror coating, the effect is not much worse than the former.

When the bicycle was first introduced, only the nobles could afford this expensive means of transportation, and in order to spread the word to the masses, in addition to the hype, Roland also planned to implement an installment payment system to minimize the pressure to buy.Of course, only those who have obtained the identity card can apply for this payment method from the city hall.

The three tossed in the garden for an afternoon, Carter Lannis, worthy of the name of the chief knight, took the lead in mastering the riding skills; the iron axe followed closely, and the second successfully circled the garden.Only Barov tried more than a dozen times without success, either crookedly and about to fall, or unable to move in a straight line.Finally, Roland had to let Sorrowa draw a static scene in which he stood by his bicycle and held his hands to the handlebar.

“Is that all?”The witch asked after completing four huge posters.

"Two more words," Roland thought for a moment, "the new era of mount, I have this, you will have it."The following is written: "The bicycle factory recruits workers, has a good salary, is well paid, and has the opportunity to get a new car that belongs to you for free."Enroll with the City Hall through primary education.“

...

After finishing the bicycle posters, the prince returned to the office, and while the dinner was still some time away, the guard called Caimo Squeir.

Now the development of mercury retinoic acid has finally made a breakthrough, and the development of a new generation of weapons can also be put on the agenda.There is no doubt that the caliber of the hot weapons era represents justice, and the speed of fire represents freedom; the greater the power, the more glorious, the more the turret is equal... But an embarrassing problem is that according to this development, the two acids obtained by the laboratory law will soon not keep up with the consumption.

For example, if you want to increase the rate of fire, you must abandon the black gunpowder with more residues and change to smoke-free-emitting drugs - that is, tampon, or a mixture of tampon and nitrochemical * glycerin.The same is true of high-power explosives, trinitro-benzene (T.N.T.) can not do it, can be replaced by nitrification starch, in addition to poor stability, the power is even greater than T.N.T.

No matter what, you need a large number of high concentrations of fuming nitric acid, purification of nitric acid requires a lot of concentrated sulfuric acid, these are not the laboratory production can meet.In other words, there is no way to use the industrial law to extract two acids, even if more efficient weapons are developed, they will be caught in the dilemma of no bullets.

When the chief alchemist walked into the office, Roland said, "I have a new task to give you."

"Say," said Kemo, shrugging, "as long as it's not a ceremony."

“I need more acid, and the current production of the chemical laboratory alone can no longer meet my needs, so your new task is to design a chemical system that can produce two acids efficiently and easily.”

“Chemical...systems?”He looks a little confused.

"Yes, consisting of a complete reaction device, as long as the input of raw materials, you can continue to produce finished products," Roland briefly explained the nature of industrial production, "I do not know much about this part, can only rely on yourself to slowly ponder."

That said, the prince also knew that this was a very difficult task, and it was likely to take years to study, and it was not necessarily fruitful.After all, the other party can rely on, but some of the basic reaction principles and chemical equations on the primary chemistry.

"I see," said Kemo, "that these things you mention really refresh me."

"Whether you can finish it or not, two acids are something I desperately need."Rolandton said, "Therefore next month I plan to expand three more laboratories in the Redwater River and recruit qualified candidates from the people as experimenters."If you don’t have time to teach them, choose a few disciples to take care of them.After all, the industrial acid method is a very long research project.”

Perhaps because of the temptation of Medium Chemistry, he agreed, "Yes, Your Highness."

After Kemo Squeer left, Roland sighed softly.

If the industrial acid method does not see hope, it can only let Lucia follow the battle to purify the acid, after all, when the war comes, he needs more powerful weapons to win the town.

Roland opened the drawer, intending to eat some fish to relieve boredom, but found that the drawer for storing snacks was empty.

He looked up and saw that a dried fish had been handed over to his mouth.

“Are you looking for this?”The blond woman smiled.

Roland bit the fish and couldn't help but start his mouth, "I thought you'd stay in the fog for the rest of your life."

"That's fine, at least no one can see me, but I can still see you."The nightingales skimmed their mouths.

Originally a little dull mood unknowingly dissipated a lot, see the other side familiar appearance, he can not help but relax, "you said before, do not know what kind of expression to show ..."

“Huh?”

"Actually, it's good like that."(Unfinished.)
