Murphy sent the Alsace father and son away, and hurried to the laboratory that Carolin asked for next door.

Carolon's laboratory is one of the largest rooms in Murphy's castle, and Carolon specifically asked Murphy for quick and easy study of Murphy's drawings.

At this time, Carolon dispersed the illusions on her body, revealing her original skeletal body, and even threw aside the magic robe she was wearing on her body.

When Murphy entered the house, Carolon was carrying a sledgehammer, clanging against the huge machine in front of him.

"You're here, sit there and wait a while, the last few gears of this watt steam engine are ready. ”

Carolen's skull didn't return, and she continued to tinker with the machine.

Murphy sighed, looking at the mess on the ground and the piles of parts and nails that were clearly enchanted and "incorruptible", so he decided it would be better to stand for a while.

"Where have you go?" Murphy leaned in, looking at Carolon as he screwed onto the machine.

"There are still a few screws left, and you can activate the magic circle, should I say it, this screw you designed is really convenient, fast and stable, and can be made in large quantities. Carolon put down her homemade wrench, picked up another screw, and put it on a threaded hole in the wheel.

Murphy didn't speak, silently examining the Watt steam engine in front of him.

Compared to the Seville and Newcomen steam engines that Carolon had successfully built before, the Watt steam engine was much smaller.

And after the production of the first two steam engines, Carolon became more and more comfortable with the production of machines.

The steam engine made by Carolon was very different from the earth-style steam engine, but the general principle of operation was similar.

Take, for example, the Newcomen steam engine. Its fuel furnace has been transformed into a small geocharism magic circle, the water evaporates to form water vapor from the boiler into the piston, the piston is jacked up and filled with pistons, and then the switch of the "frost greeting" circle is turned on, the cold frost gas enters the cylinder, cooling the steam to form a vacuum, under the action of atmospheric pressure, the piston is pressed back again, thus forming a working cycle, which sounds very powerful, but to put it simply, it is essentially a boiler.

The magically modified Newcomen steam engine can work in this way about thirty times per minute, and although it is very efficient, it does not have much practical value, because its piston only has two functions, forward and backward, but can be used for water lifting.

Compared with the Watt steam engine in front of him, the efficient Newcomen steam engine is still overshadowed.

Because Carolon wanted to make them one by one in the order of progress, it took half a month before it was the turn of the current Watt steam engine.

Of course, the reason why Carolon Carolon made the Seville steam engine and the Newcomen steam engine was actually just to practice and accumulate experience, and it did not have much practical value, and the Watt steam engine that was currently being studied and produced was the beginning of the real change of this era.

With a watt steam engine with a crank turn, it can really be put into practical use.

The function of crank rotation is to convert the linear motion of the piston into rotational motion, which allows the steam engine to drive the rotating machinery, such as wheels.

"It's done!" Carolon fixed the last wheel to the steam engine and tossed the wrench aside, finally completing the first test of the Watt steam engine.

"Let me see!" Murphy shouted excitedly, putting his hand on the machine, feeling the charm of the magic industry.

"What's the hurry, this is the beginning!" Carolen's soul fire flipped for a moment, equivalent to rolling her eyes, and then poured a large bucket of water into the boiler, activating the circle on the steam engine by the way.

A red light rose from the Earth Flame Circle, but it didn't feel much heat, and it seemed that Carolon had also added a heat insulation array.

It only took a dozen seconds for the entire steam engine to move.

The water in the boiler quickly tumbled and boiled under the heating of the Earth Flame Array, producing a large amount of water vapor, and the water vapor pushed up the piston and rushed into the cylinder on the left, causing the wheels to start rotating, and the rotation of the wheels pushed the valve to move, and the steam rushed into the cylinder on the right, repeating this action.

The two-cylinder linkage allows the steam to alternately push the piston forward and backward, and the whole process is fully automated, without being as cumbersome as the "big toys" originally made.

In addition, this steam engine is also equipped with centrifugal governor and steam regulating valve, and the machine control has been greatly developed and improved.

"Hahahaha! Great, that's what I want. Murphy laughed, with this steam engine with practical value, it can really change this era.

"Look at your useless appearance, a machine?" Carolon sneered, glancing disdainfully at Murphy.

"But, absolutely, with a steam engine with a crank rotation and a two-cylinder linkage, we can make steam locomotives like trains in the future!" Murphy couldn't contain his joy, trying to calm himself down.

"Train, steam locomotive, what's that?" Carolon was a little confused by the unfamiliar word that popped out of Murphy's mouth.

"Oh, these are one of the means of transportation that I envision for people in the future, who can run more than 100 kilometers per hour, and it only takes about a week to run from Remlos Fort to Lorraine. Murphy remembered that this was the Otherworld, so he roughly explained it to Carolen.

"So fast, do you have any drawings? Show me quickly! I'll make it for you in a few days." Carolon confidently patted her sternum and raised her jawbone.

Murphy was only as tall as Carolen's chest, and could only look up at him.

"There are drawings, but even if you make them in just a few days, you won't be able to use them on a large scale in a short period of time. Murphy shrugged helplessly.

"Give me a reason. ”

"Because the movement of the train is to move on the tracks, and the laying of the tracks is a very troublesome matter, and the rails and train materials are also a big problem. ”

"Can't it be solved?"

"We don't have enough money, we need a lot of money to get the track on it. ”

"Isn't it very profitable for you to sell arquebuses?"

"But it's a one-off business, and you know how easy it is to copy. ”

Murphy's words silenced Carolin for a long time before she continued to speak.

"Tell me, what do I need to do to give the drawing?"

"Lord Carolon really understands the righteousness! It's not a big deal, I just hope that you will make more semi-mechanized machine tools and sell them to the nobles who are interested in making arquebuses when the time comes. Murphy squinted his eyes and laughed.

"I know that your kid is not easy to build, that machine tool is not easy to build, and it is thanks to me that I can build it, otherwise I will have to poke it for a long time. Carolon snorted.

"Allocate funds, prepare the materials, and start building now. ”

Thanks to being a lich, he can work and research without sleep and always full of vigorous energy, and if he is replaced, he will be tired to death.
