Great Qin Shihuang can hear my heart

Yingxi originally wanted to strike while the iron was hot, but Emperor Shi Huang gave him a sideways look and almost scared him into incontinence. How could he dare to continue talking?

These ten good students and good craftsmen who attended the class were also terrified by Li Lin's menglang behavior.

Fortunately, Li Lin withstood the pressure of the first emperor and shocked the ten of them, otherwise the ten of them would have knelt down directly from their seats.

After all, the first emperor's aura was much stronger than Li Lin's.

Master Li can withstand it with difficulty, which is enough to make them feel admirable.

of course.

This is due to the fact that Li Lin grew up under the red flag. He has always dismissed emperors and high officials.

But even if he possessed such values, he would still be intimidated by the aura of Emperor Shihuang.

As for the others, it's already amazing that they didn't scare the pee on the spot.

"Gauss is very smart. He is the prince of mathematics. Look at this trapezoidal formula. If we want to make gunpowder, do we have to design a storage device? Look at the characteristics of this trapezoid. Is it narrow at the top and wide at the bottom? If we narrow the opening on the top and make it into the lead wire of the gunpowder, it will not only be convenient to carry, but also prevent us from using the opening by mistake for the gunpowder..."

Now he is not as free and easy in lecturing as before.

After all, the first emperor was sitting behind the crowd.

Looking at his bright red and bloodshot cheeks, Li Lin knew that his anger had not completely dissipated.

If you don't say something about the four great inventions at this time, His Majesty will definitely think that he is fishing here.

He Li has a big face, but it doesn't mean he can be lawless.

In Daqin, you can offend the first emperor.

But you can't fool him, he hates people who lie to him the most in his life, didn't the more than 400 warlocks get tricked and killed by him because of cheating him?

Chun Yuyue, that rotten Confucian, spent most of his life criticizing the system promoted by the First Emperor, isn't he still living a good life?

So, don't let him feel cheated, let him understand that he is doing something related to the four great inventions at this time.

In this regard, Li Lin can be said to have worked hard.

【Your Majesty, alas, how can I explain the role of mathematics in other aspects?Your Majesty now [-]% thinks that mathematics is arithmetic. If he thinks it is arithmetic, he will not pay attention to mathematics. This will definitely be disadvantageous to me. I have to find a way to explain the importance of mathematics. Yes, use This way! 】

"Master Li, you said that we should use a trapezoidal design for the gunpowder casing, but the villain thinks why not use a larger gunpowder casing, use a round one, and then let people ignite it and throw it out. Wouldn't it be better? "

At this time, Mo Zhiyuan, the descendant of the Mo family, suddenly raised a question.

Although he is gray-haired and extremely old, his interest in learning mathematics and cognitive ability are far superior to those of the other nine.

[Oh, isn't this when I just wanted to sleep and I came here with a pillow?Mo Zhiyuan, Mo Zhiyuan, you old man really helped me a lot, I was just trying to draw out physics! 】

"Mo Zhiyuan, your question is very good. Indeed, we can skip this 'T' bomb and directly create a round bomb that is more powerful and can be filled with more gunpowder. However, you have to consider Momentum issue."

"Power problem?"

Everyone's expression changed, and they fell into deep thought.

Even Shi Huangdi, who was sitting beside him angrily, couldn't help thinking: This bastard, I'm so mad today!However, according to the content of his course, it has something to do with the gunpowder, but what is the problem of motivation?After gunpowder was developed, didn't the fuse be ignited and let people throw it out or tie it to a bow and arrow and shoot it out?

"My lord, the power issue you mentioned, we can completely train the throwing soldiers with precise throwing, and let them throw to the enemy's position the moment the fuse is lit. Can do an effective strike..."

"No, no, no, Mo Zhiyuan, you made a metaphysical mistake. If you use human power to throw gunpowder, how is the firearm derived from the gunpowder different from ordinary big rocks? An epoch-making invention will change the pattern of the entire world, and this gunpowder is the same, what you think is too limited."

Li Lin smiled and interrupted his speech politely.

Regarding his idea, Li Lin adopted a completely negative attitude, and then under the doubts of everyone, he went on to say: "You see, if you use human power to throw gunpowder, the thrown gunpowder will become A parabola. At this time, the gunpowder is completely driven by the power of the throwing hand before throwing. When it is in the air, it will be resisted by the air and generate friction. At this time, we will use the Newton's theorem I mentioned just now. , take a look, what will happen to our power..."

"Attenuated?"

"If you use it like this, you can only throw it less than two miles away with human power?"

"Isn't this too short?"

"Two miles away, if there are too many troops, will the enemy take advantage of the situation to cover up and kill them? It's not within the safe range at all..."

There was a lot of discussion among the people.

As Li Lin's explanation deepened, everyone discovered that using human power to throw gunpowder is the most stupid way.

Bows and arrows can be used to bind gunpowder for delivery.

The amount of gunpowder applied is too small to cause effective damage.

Emperor Shi Huang couldn't help but nodded as he listened. Obviously, he understood what Li Lin explained. Of course, he didn't listen to a word of Newton's laws of motion.

But it doesn't prevent him from understanding.

As a king, the most important thing is to have a certain learning ability.

The First Emperor is not lacking in this point, his learning ability is one of the best in the Great Qin.

Not a genius, but a rare existence.

Seeing Li Lin who was holding his chin with both hands of the First Emperor, he was suddenly overjoyed.

【call!Your Majesty is finally not in the state of rage just now, thankfully I almost ran out of words, but this Majesty has always been a sensible person, how could he be so angry after just one glance at me?If no one deliberately spoke ill of me in front of His Majesty, it is unlikely that His Majesty would be so angry. 】

Now, he finally calmed down.

Thinking of the abnormal angry action of the first emperor, he couldn't help but put his eyes on Yingxi who was beside him!

[Could it be Yingxi?It seems that I haven't offended anyone else in the construction department except for those members of the Wang family and Li Si's henchmen these days, right?Is it Man Yin?No, no, it can't be Manyin, that girl was fooled by me and couldn't find her, how could she harm me like this?It seems that in all likelihood, it is this Yingxi who is playing tricks behind the scenes! 】

Li Lin thought about it a lot, and thought about all the people who offended these days, and finally decided that the person who caused the ghost is most likely to be Ying Xi, who looks harmless to humans and animals at this time.

After the first emperor heard Li Lin's quick reaction, he couldn't help but sighed in his heart: This bastard, I didn't expect, he scolded me very stupidly on the surface, dared to give me face, but never thought that in his heart he was With such calm thinking, he was able to quickly determine who was framing him behind his back.

Such a powerful mentality.

Even if it's me, I'm afraid I can't touch it?

If I had had his mentality in the past, maybe I wouldn't have exposed my edge prematurely, which would have caused that Lai Ai to commit murder and strike ahead of time.

In this way, Lu Buwei's group will be smashed more thoroughly by me.

The turmoil in the back of Daqin is surging, maybe it will stop a lot because of it.

Just when the first emperor praised him for such a mentality.

Yingxi's mood is not stable.
