It wasn't an apple that hit Newton.

"Strange noise?"

Lavoisier was quite pleased with his perfect room, a satisfied smile on his face: "Will ghosts come to scare me tonight?"

"There are no ghosts or anything like that."

Susie glanced at Li Cheng not far away and said with a sneer, "It's just that Lord Newton often comes to Li Cheng's room to ask him to tell stories, and sometimes, while they're telling stories, they do things that disturb the peace..."

A disturbance to the neighbors?

Lavoisier recalled the incongruous large bed in Li Cheng's room, and seemed to vaguely guess what sounds he would hear. The satisfied smile on his face gradually disappeared.

A strategically vital location...

The perfect room...

Lavoisier was filled with deep regret, but it was too late. His luggage and furniture had already been moved in, and it would seem very strange and capricious for a temporary guest to suddenly ask to change rooms.

What exactly did I do before?

Lavoisier thought it over and realized that he could only blame himself for being careless and overlooking this crucial factor. After all, he had put a lot of effort into choosing the room, and Susie had even advised him to change rooms, but he had politely declined, citing the good lighting.

Since we can't blame anyone else, that means...

Am I amazing?

Chapter 232 Your Husband is Great

Lavoisier's settling-in went smoothly, and that evening Newton had the chef host a small banquet as a formal welcome to her as she moved in with her bags.

At the banquet, besides carefully explaining his purpose (to help with the development of his territory), Lavoisier also tried to build a relationship with Newton so that he could extract information from him later.

And so, the day came to an end.

After washing up that evening, Lavoisier returned to his new room with somewhat heavy steps, while Newton, with light steps, habitually slipped into Li Cheng's room...

------

The next day.

To avoid suspicion and for work purposes, Li Cheng officially began working the day after settling Lavoisier in. The first thing he did was to have Lavoisier learn a series of techniques related to steelmaking and iron smelting.

"In the future, you can assist me with my work in the coal and steel industries. When I'm not around, you can answer questions for the masters and workers who don't understand."

"The principle isn't difficult to understand, and I believe you can do it."

After a brief introduction, Li Cheng began to explain his approach—the crucible steelmaking method.

The crucible steelmaking process involves melting metal in a graphite-clay crucible to produce molten steel. In 1742, the Englishman Hunzman cut carburized iron into small pieces and placed them in a sealed clay crucible. He heated the crucible from the outside, and the iron continued to absorb carbon from the graphite, melting into high-carbon steel. This steel was then cast into small ingots and forged into the desired shape.

The principle of this iron smelting method is not complicated. The key point is how to make a high-temperature resistant crucible, and Li Cheng already has the corresponding technology in mind.

Materials science has arguably constrained the development of many modern technologies. From steel in the first industrial revolution to battery capacity in the 21st century, materials science has played a crucial role. However, this field often relies on luck, and there are few fixed patterns to summarize its rules.

Incidentally, China had already invented liquid smelting: using a blower to fully combust the fuel, melting the iron ore with this high-temperature flame, and continuously adding charcoal powder to keep it liquid, allowing the slag to be fully extracted, and finally using the liquid iron-carbon alloy to cast agricultural tools and daily necessities.

If freshly molten pig iron is poured in and stirred, better quality steel can be obtained—this practice continued into the Great Leap Forward era.

To get back to the point, steel is the foundation of everything, from small parts like springs to large machines and trains; it's needed for almost all industrial products.

If electricity was the main theme of the Second Industrial Revolution, then coal and iron were the main theme of the First Industrial Revolution.

......

Li Cheng imparted a comprehensive and thorough theoretical knowledge to them.

In this era, Lavoisier, as a chemistry professor who had embraced atomic theory, was one of the few who could keep up with his line of thinking.

Although supporting such a beautiful girlfriend would not be difficult for Li Cheng at all, Lavoisier was not the kind of person who liked to live a life of leisure. Coincidentally, the steel and coal industries were a good fit for her, as they were related to her major.

In this way, not only was there ample reason for Lavoisier to remain in the territory, but he also gained a trustworthy helper, allowing them to see each other daily.

A win-win situation; Li Cheng won twice.

When the conversation turned to serious matters, Lavoisier's expression became quite earnest, as if he were simply asking a question to a student: "There's something I don't understand here, why...?"

After thinking for a moment, Li Cheng replied, "Because of blah blah blah..."

After asking a few more questions about things he didn't quite understand, Lavoisier couldn't help but cover his lips with his hand and yawn slightly.

"Ugh~~~"

Although she was quite cute, Li Cheng noticed a hint of weariness on her face and a somewhat dim look in her eyes.

"What's wrong? Didn't you sleep well last night?"

He asked with concern, "Tell me if there's anything you're not used to, and I'll help you fix it."

It would have been better if he hadn't asked. But as soon as he did, Lavoisier revealed a very resentful look in his eyes, stared intently at Li Cheng, and said through gritted teeth, "It's all your fault!"

"Blame me?"

Li Cheng was very puzzled.

"It's all your fault!"

Lavoisier clenched his fist and angrily punched Li Cheng in the chest: "Think carefully about what you did last night!"

"My actions..."

Li Cheng recalled for a moment.

After overcoming the embarrassment of being caught in the horse riding game, Newton habitually sneaked into his room last night and continued to press him to tell stories, and then... well.

Perhaps it was because absence makes the heart grow fonder, but after a few days apart, Li Cheng took advantage of Newton's concentration on listening to the story and began to make advances towards him. Having done it so many times before, Newton didn't resist, and the two unlocked quite a few new positions.

This was a real problem for Lavoisier, since you can't expect a couple deeply in love to control the volume at home, especially since the room she chose was in a prime location where it could be easily monitored.

It was bad enough that the guy I liked already had a girlfriend, but now I have to listen to the sounds of my boyfriend and his girlfriend being intimate every night, and I can't even hold his hand or kiss him. It's like having an affair—wait, it really does seem like having an affair?

In short, is there no justice left?!

Thus, on the one hand, driven by her ingrained bodily instincts, the noise from Li Cheng and Newton made her feel restless and agitated; on the other hand, a strange sense of being a minotaur lingered in her mind, a mixture of humiliation and a peculiar thrill...

Under the dual stimulation of physiology and psychology, Lavoisier dawdled until late at night before finally falling asleep, and he had no energy at all today.

If this continues for a while, she might one day lose her temper and, without thinking, drag Li Cheng into the room and seduce him...

......

After realizing that it really was related to him, Li Cheng felt a little embarrassed.

It turns out that Lavoisier overheard him and Newton being intimate, which caused her to lose sleep... Come to think of it, that sounds really strange. Aren't people usually the ones who secretly make out with their lovers behind their wives' backs? He's the opposite here.

Li Cheng thought for a moment and offered a solution: "Um... how about you change rooms? I think the others should understand."

It was indeed a solution that would solve the problem once and for all, but Lavoisier didn't want to do that. She had carefully chosen her current room; it had good lighting and was close to Li Cheng, so she could easily sneak into his room from time to time. But if she were further away, it certainly wouldn't be as convenient.

"Do you have a way to not make a sound?"

Lavoisier thought for a moment and offered a suggestion—as the saying goes, "ignorance is bliss," meaning that if you can't hear it, then nothing has happened.

"This is too difficult," Li Cheng said, rubbing his hands together. "After all, I wasn't the one who made the sound, right...?"

“Then let’s try another approach.” Lavoisier also felt that this was not quite reasonable, so he suggested another method: “From now on, if you need anything, go to Newton’s room. As long as you’re not in your room, I won’t be able to hear you.”

Although this was one way, Li Cheng had a flash of inspiration and came up with a better idea.

Under Lavoisier's gaze, he slowly spoke: "Wait, perhaps this can be turned into a favorable situation."

?

Lavoisier gave him a strange look: "How could this possibly benefit me?"

"Correct."

Li Cheng held up a finger, his eyes gleaming, and said, "Think about it, we were worried about being exposed when we were being intimate in the castle, mainly because of the smell and the noise—the noise was okay, but the smell was something that couldn't be hidden no matter what."

"But if I take Newton back to her room after we've been intimate, you can take the opportunity to come to my room and be intimate with her."

"As long as you control the volume, you can blame the smell on Newton. If you do it a few times, no one will suspect anything."

Li Cheng gave his own idea a thumbs up.

As we all know, the room after intimacy will be filled with the fresh scent of photinia flowers, and the best way to cover up this scent is to use another fresh scent instead.

As for the issue of having to pay two separate "labor taxes"... well, it's something you have to accept if you want to be a scumbag, and there's no escaping it.

!!!

Lavoisier was stunned by Li Cheng's genius-level lewdness and opened his mouth but couldn't speak.

This...this...this...could this be...the anti-Cowboy?

The offensive was reversed. Originally, they could only cower in their room like defeated dogs, hugging their pillows and listening to the intimate sounds from next door, enduring strange play similar to cuckoldry, suffering double torment both physically and mentally.

But through this method, not only can one obtain physical and mental satisfaction, but one can even leisurely add a comment afterward:

Your husband is amazing.

Chapter 233 is titled 233

After the brief interlude, Li Cheng spent the entire day in his study openly imparting his knowledge of coal and iron to Lavoisier—part of which was spent teaching the crucible method, while the majority of the time was spent satisfying Lavoisier's curiosity about the underlying principles.

After all, she's his girlfriend; he can't just treat her like a working stiff...

Midway through, a maid came to serve tea and water, while the academically challenged Susie tried to observe something unusual but to no avail, and the bored Newton even came to audit the class for two hours. However, the two, in their teacher-student mode, appeared perfectly normal, and no one noticed anything amiss.

It was evening.

Seeing the sky outside the window darkening, Li Cheng tapped the table and said, "That's about enough for today."

"Almost there."

Lavoisier insisted that he could continue, saying persistently, "Just a little bit more, just a little bit more and I'll understand it all."

"Let's talk about it tomorrow," Li Cheng firmly stopped him. "You haven't had a good rest yet, and you've been studying all day today."

Lavoisier spent the entire day understanding and absorbing new knowledge. Although she remained energetic, even more so than when she woke up, thanks to her curiosity and interest in the subject matter and the fact that she could always ask Li Cheng questions and discuss things with her, the physical and mental exertion she experienced was undeniable.

After Li Cheng's strong dissuasion, Lavoisier did feel a wave of weariness wash over him and stopped insisting.

I do seem a bit tired.

After lazily stretching in the sunset, revealing his beautiful figure, Lavoisier, seeing that there was no one else in the study except for Li Cheng in front of him, joked, "Teacher, it seems like it's time to go home after school, shouldn't we?"

"Ok?"

Li Cheng was taken aback, then looked at Lavoisier, who was sitting upright with a serious expression, looking like a well-behaved student waiting for the teacher to dismiss him.
