Cousin Linar had been looking at Charles' sketches for a long time.

Her face became more and more serious, and her pink eyes flashed with confusion or shock from time to time, and then her hands would tremble unnaturally slightly.

The crown prince Leo and the little girl Olive no longer had the curiosity they had at the beginning, and quietly looked at Linar from the sidelines, their faces were equally serious and cold.

Leo is Adele's student, Linar is Adele's daughter, the two know each other very well, Leo naturally knows Linal's level in this kind of "alchemy", how important it will be to be able to make Linar lose his temper.

Because of time constraints and someone's secretions, the drawings that Linar got in her hands were actually the simplest sketches, and there were only half of them, and many details were not drawn, but the working relationship between the intake and exhaust valves, the inertia flywheel, and the expansion cylinder was drawn.

However, the schematic diagram of the steam engine in the nine-year compulsory education textbook is taken from the reciprocating steam engine in the mature period, which is very different from the early steam engine, and the earliest steam engine does not even use high-temperature and high-pressure steam to directly drive the machinery, but uses the vacuum negative pressure after steam cooling as the power, and the efficiency is very low.

The steam engine drawn by Charles already had mechanical components such as crankshafts and reciprocating cylinders that greatly improved conversion efficiency, which was obviously beyond Linal's knowledge.

This is already the simplest working principle of the steam engine that Charles knows, and if it is improved in combination with the professional knowledge of his science and engineering man, it is estimated that it is possible to make Linar bow his head on the spot.

After a long while, Linar carefully folded the drawings and put them away, "Charles, this is a drawing you copied, right? Uncle Bourman showed you the original drawing of this drawing?"

Charles nodded slowly, he was indeed copying the drawings, but the samples he copied were illustrations from the nine-year compulsory education textbook, not some original drawings in the collection of Bourman Chevalier.

"There are a lot of intricacies on this drawing, and it will take me some time to understand it thoroughly, but the value is high and we can collaborate on research. ”

Linar said solemnly to Charles: "We will build a laboratory in the Ruhr, I now sincerely invite you to come to the laboratory and study the steam engine with us, I believe that in the near future, the steam engine will become the most ....... in the world."

"I think you've mistaken your cousin. ”

Charles looked at Linar, who was a little stunned because he was interrupted by himself, and said, "Since I was invited to study together, then the research laboratory cannot be built in the Ruhr, but only in Lorraine. ”

"Built in Lorraine?"

Linar was stunned, obviously not expecting Charles to make this condition.

"Yes, it was built in Lorraine, and you are responsible for providing us with or training fifty skilled steelworkers, and I am talking about craftsmen, not blacksmiths. ”

“.........”

This time, it wasn't just Linar who was stunned, but Leo and Olive were both stunned.

"Charles, are you kidding? Fifty skilled craftsmen? Do you know how many of them there are in the whole Ruhr city?"

"It's definitely more than fifty, and with your and His Highness Leo's abilities, you can definitely draw them out. ”

Charles didn't care about Liner's anger at all, the steam engine was not a sophisticated technology in the previous life, but in this world with an illiteracy rate of more than 90 percent and a scientific illiteracy rate of more than 99 percent, it was the crystallization of top technology at the level of a high-thrust-to-weight aircraft engine or a high-precision lithography machine.

"This kind of cross-era technology, without a science and engineering man like me, can you have fun?

Flames began to flow from Linal's small nostrils again, and she turned her head to glare at Leo, who was quick to speak.

"Earl Charles, Teacher Adèle has been studying water vapor engines for twenty years, and her experience and technology must be richer and more comprehensive than yours, so I think this collaborative research should be based on us Pruss, do you think what I said is reasonable?"

"Is it richer than me, more comprehensive than me, and what are you coming to me for?"

“........”

Leo was speechless for a moment, and Charles's way of speaking was too direct to play with them amicably.

"Charles, the steam engine is much more complicated than you think, a drawing is important, but it doesn't mean all, we have failed I don't know how many times, many times we don't know why it failed. ”

"Cousin Linal, if you don't think a drawing means anything, you can give it back to me. ”

Charles smiled and stretched out his hand, as ruthless and unrighteous as those "happy breakup" scumbags.

Linar's palms clenched reflexively, as if she wanted to grasp something alive and keep it from flying away.

"Cousin Linar, I believe that with your knowledge, you should be able to see that the drawing I drew is a sketch, after all, I don't have that much time to give you a complete drawing, let alone explain to you the detailed principle......."

"Incomplete?"

Linar didn't wait for Charles to finish speaking and became angry, no wonder she couldn't understand it after reading it for a long time just now, it turned out that this drawing was incomplete, and her cousin actually left a hand.

"Count Shire, your behavior is not in keeping with the manners of a gentleman. Seeing Linar deflated, Leo came up to help without waiting for her to say hello.

"So what kind of demeanor do you have now? What is the real purpose of your cooperation with me? Is it because of the wealth of Lorraine? Or after twenty years of studying the steam engine, I can't find the reason for the failure? The drawings are mine, and if you want to cooperate, you have to exchange sincerity, and if you don't think it's worth it, then don't cooperate, what's the problem?"

Charles stabbed the window paper with a shot, and said a lot of ugly things bluntly, so startled that the little girl Olive hurriedly came over and grabbed his sleeve, and kept giving him a look to calm down.

But Charles's snort, apparently annoyed Linar, she took out the half of the blueprint and waved it angrily, "You have to change fifty craftsmen for one drawing, and you have to build a research laboratory in Lorraine? If I agree to this condition, I will be a fool!"

Leo Hohenzollern also said solemnly: "Count Shire, Teacher Adèle will not agree to such conditions of cooperation, I think she will be very unhappy when she learns about this. ”

Charles shook his neck and said lightly: "What I paid is not only a drawing, but also all the troublesome solutions in the development of the steam engine. ”

“.........”

"You know the drawings?"

Although Linar didn't understand what a "schoolboy" was, she remembered that Charles meant that he had more than just a drawing, but all the knowledge hidden in it, which Bulman had studied for twenty years..........

"Smack!"

Linar slapped the table on the table, and the windows buzzed with a loud noise.

"Where's my room?"

“.........”

"What?"

Charles couldn't help but burst out a hometown dialect in a daze.

"You should have received my mother's letter, she asked you to prepare a room for me, right?" Linal's whole face turned red, and she didn't know if she was angry or what.

Charles turned his head to look at Olive blankly, and Olive blinked, who was also confused, and said, "Last time you said that you would prepare a room for Cousin Linal, and I have prepared it." ”

"Guest room? You let me stay in the guest room? Should I stay in the guest room?"

Charles looked at his cousin, who seemed to be making trouble, and hated in his heart, "Your sister, why do you want to live in the master room if you don't live in the guest room? Where do I sleep that night?"
