The young man thought happily in his heart, and then, he looked at the scientific beautiful girl's smug expression, and his eyes were already rolling, but he was looking at the three views on the table.

After thinking about it, he smiled and said, "Little junior sister, this is ......"

He pointed with a grin.

Li Xi's face suddenly turned slightly red.

Hell, how did I forget to put it away?

The girl thought angrily that she had already made a little bit of a thief and was caught.

"It was you who handed over these three-view principles, cartography and centrifuge structure to your grandfather, and asked him to send them to the Royal Academy of Sciences for certification and patenting. I've just made a copy of it for reference...... Oh no, grandpa told me to check for you again to see if there was anything wrong, but I can't be considered to use it secretly without authorization! ”

Her eyes rolled, and she was already reluctant.

Xie Xiuqi smiled slightly: "Little junior sister wants to use it, it's my honor, why do I need authorization, let alone say it secretly?" ”

Li Xi was stunned.

This guy ...... It's really a world of difference from the original bastard......

The girl thought in her heart, but heard the young man say again: "It's just a little junior sister, you have changed and changed these, but why?" But want to improve this centrifuge? ”

He pointed to another pile of paper with a mess of patterns on the side, and laughed again.

"yes." The girl replied, and suddenly, her eyes lit up.

The person in front of him, but he was praised by his grandfather for having an extremely keen eye on scientific things.

I also think that most of it is true, otherwise I would not have heard it at the beginning, and I would have said in one word what the strangeness of the gunpowder was.

If only he could......

But he has never had a good face for him......

Let's not say that I helped him back just now, although it is the simplest knowledge......

No matter! Even if you make him laugh again, you have to know if there is a way. Just, even if he owes him a favor.

The girl's heart was already thinking about it a thousand times, and then, the obsession with science made the beautiful girl of science ruthless.

She thought about it, and her little face was already slightly twisted: "That...... Thank...... So what kind of teacher...... Brother, don't you know if you can improve it? I, I've had some experiments, but I can use it, and I need it to work better. ”

She looked at it with great anticipation.

Xie Xiuqi shook his head: "It is very easy for this thing to have a high speed, but the structure will definitely be unstable. However, it requires extremely precise parts that cannot be deviated in the slightest, as well as a constant output of extremely high power sources. There may be a way to think about the parts, but the force is applied constantly...... With the technology at this time, I'm afraid ......"

Li Xi was immediately full of frustration when he heard this: "I know...... Hey......"

The girl said in disappointment, she sighed faintly, but saw that the young man smiled again: "Little junior sister wants to improve this thing, I think it is to separate and combine the more tightly combined mixture, right?" ”

"yes...... But there's really nothing to do about it now, and it looks like we'll have to think of another way......"

The girl nodded in frustration, but saw that the young man smiled again: "If the little junior sister only wants to do this, there is no need to toss this centrifuge anymore...... I called it extraction – in fact, the one that I separated from the fire was the simplest extraction. ”

The young man smiled leisurely, and explained to Li Xi in detail the extraction method of using the different solubility of solutes in immiscible solvents to extract solutes from the solution composed of another solvent with another solvent, and in the language accepted by science of this era.

Immediately, he explained in detail to the girl a variety of extraction methods such as solid-liquid extraction and liquid-liquid (aqueous phase) extraction.

Li Xi's eyes gradually brightened: "That's right...... How did I not think of that? Extraction...... Wonderful, wonderful! ”

The girl cried out for joy.

Then, she looked at Xie Xiuqi even more strangely: "Xie ...... Thank...... The ability of the senior brother to think in science is really impressive. This extraction method will also spread throughout the empire in the name of the senior brother - it is too convenient to use in chemical experiments to extract more purified substances. ”

Xie Xiuqi smiled slightly: "Little junior sister already understands, you can use this method to try how to apply it to make your gunpowder." ”

In fact, I only know the general direction of picric acid production, and I don't know anything about how to make it industrially......

Xie Xiuqi smiled bitterly.

Damn, I knew that I should have studied hard back then...... Mom is right, knowledge is power, and those who study well are good children, and it doesn't matter how much you need in modern times - once you cross, immediately cow b! Boys, you should study hard in order to prepare for the crossing!

The young man thought strangely in his heart, but Li Xi was already smiling: "Then I don't need you to work hard, I have my own time to experiment!" ”

Immediately, she looked at Xie Xiuqi suspiciously: "Master Xie...... How did my brother know that I was doing this? ”

Xie Xiuqi smiled: "Who else can make the little junior sister remember when she is preparing for the provincial exam, but who else can there be?" ”

"Yes......" Li Xi suddenly nodded: "Everyone is ...... to me No, we have high hopes for that gunpowder, and I will do everything I can to do it. The coal paste refining is too difficult, and it can barely be made in the laboratory, but it cannot be produced on a large scale. So I wondered if I could think of a way to separate it. ”

I don't seem to be able to do anything about it...... Xie Xiuqi suddenly touched his nose and smiled bitterly in his heart.

The scientific name of coal paste is remembered as coal tar, but coal tar? At most, I remember that industrial production seems to be dry distillation? As for how to dry distill, is this era close to this level of technology...... I don't read much......

And the extraction separation...... Perhaps it can only be used to refine the useful ingredient after the coal tar has been extracted...... I really forgot......

The young man thought to himself, but listened to the beautiful girl of science again: "If this problem cannot be solved, let alone the problem of how to use it in cannonballs, which is extremely costly, how to solve the problem of using it in cannonballs...... You have to take it one step at a time, but this first step seems so difficult...... We don't know how long or what month it will take for our gunpowder to be fully effective......"

"Our gunpowder?" Xie Xiuqi suddenly shrugged his eyebrows in surprise.

I haven't paid attention yet, but now I really hear it, when did it become "us"?

The young man was already wondering in his heart.

"That's our gunpowder...... Li Xi looked at Xie Xiuqi strangely: "What I found was only a half-finished product, and what you found was a finished product that could really be used to explode and was called gunpowder." This invention is naturally the result of you and me - didn't grandpa tell you? ”

"Li Shi only said that he wanted to write to state the matter, but he didn't say ......," Xie Xiuqi touched his nose and said with a wry smile.

"The purpose of the letter is to explain that this gunpowder is the result of the combination of you and me, and that we are both inventors, so let them add your share to the name of the patent owner." Li Xi said so.

Immediately, she frowned even more: "You...... I targeted you before, also because ......"

The girl's face suddenly turned red, and she glanced at the young man with even more hatred: "It's also because of the original ...... You know! ”

She said a little angrily, and then, she was even more angry: "It's not because you were too ...... at that time It's too much, but I'm not such a cautious woman, do you still think I'm going to take advantage of this to covet you? ”

Xie Xiuqi's heart was gradually abrupt.

I thought about it. Modern people will fight to the death for patents, but ancient people ...... Not to mention a humble gentleman like Master Li. And Li Xi gradually observed that although he was targeted at himself in every possible way, he also had a reason, but his heart was also kind and innocent, how could he be greedy for his own merits?

I just wanted to help her to eliminate her bad feelings for herself, but I didn't want to add my name to it, and now, I am even more like a villain.

It's just that, from this point of view, taking Li Xi's already famous gunpowder ride, his plan to make a name for himself in science is faster...... As soon as Li Shi's letter arrives at the Royal Academy of Sciences, his name must have suddenly spread in the scientific community......

It's not bad, and in the future, there will be opportunities and resources to compensate her.

Thinking about it in his heart, the young man also smiled and said: "It's the senior brother who wants to go wrong, and I hope the little junior sister will forgive me." ”

He said with a smile, but he also acquiesced to Li Xi and Li Mao's actions.

Li Xi glanced at the young man hatefully again: "Hmph, it's good to know." ”

The girl snorted angrily, and then, she didn't know what she remembered, but she was slightly embarrassed: "This, thank you...... Senior brother, there is one more thing I want to tell you, the name of the gunpowder...... I didn't ask my grandfather to write to him asking for a change...... Actually, it should have been named by the two of us......"

She peeked at Xie Xiuqi and said.

"What does the name matter, what is the name of the little junior sister." Xie Xiuqi smiled magnificently, and then, he also looked at the girl curiously: "By the way, what name did you choose it for?" ”

Li Xi saw that Xie Xiuqi didn't care, but he was also overjoyed: "The little bear called Li Xi!" Not bad, right? ”

She smiled widely.

Xie Xiuqi was dumbfounded: "Li, Li Xi's ...... Small...... Little bear? ”

He asked, uncertain.

"yes." The girl said happily: "The gunpowder and cannonballs used in the empire today are all called Tigers, and the kind used now is the Tiger Type 3 gunpowder that has been adjusted several times by the Royal Academy of Sciences and finally determined the formula. Our gunpowder is stronger than it, and the natural name is more domineering, as the so-called wild don't meet a bear, two pigs and three tigers, pigs are too ugly, bears are the first! How domineering? ”

"Overlord...... Domineering? Xie Xiuqi muttered with his mouth open, his expression was already extremely strange.

"Of course it's domineering, the first one!" But seeing that the girl thought about it, she said again: "And I thought that since I invented it, of course I had to put my name on it, but Li Xi's bear is too ugly, so the little bear called Li Xi is cute and domineering, how good?" ”

Xie Xiuqi's face was already extremely distorted.

Why don't you call Li Xi's small breasts, that's really cute and domineering - but when I was surveying and mapping at high altitude back then, I found that those breasts were not small. Oops, speaking of which, I think of the word pink again......

He thought strangely, and finally collected his thoughts and came back to eat again: "This is the name...... Can it also be passed by the Royal Academy of Sciences? ”

"That's natural, as long as you don't have objections." Li Xi glanced at him strangely again: "Whenever the empire invents, the inventor is allowed to name it by himself and strictly abide by it." In fact, from now on, everyone can't call it the gunpowder, but should call it Li Xi's bear. ”

The girl said and said with joy again.

Xie Xiuqi's expression was incomparably blank, and all kinds of magical pictures had already appeared in his mind-

Live version: The five big and three thick royal admirals have bloody faces: Tiger 3 seems to be no good, come on, let Li Xi's cute little bear go to cao to kill them!

Romance version: I saw that it was too late and that it was fast, the domineering Li Xi little bear with a long scream, plunged into the Xiyi battleship, with a bang, the fragments splashed everywhere, the enemy ship was already burning a raging fire, and gradually broke into two, an enemy soldier cried out in the fire: Oh God, it's Li Xi's little bear!

Storytelling version: The enemy's main ship is extremely heavily armoured, and it still stands still after being shot several times. The enemy chief looked up to the sky and laughed, and when he was in high spirits, a Li Xi's little bear flew in the sky......

Thinking about it, he burst into tears.
