About the fact that the heir of Huajian School is a girl

did not expect……

"OK."

Pan Manman answered very seriously.

All the people in the Ministry of Industry: ???

They all thought they were confused.

Li Hulun patted Yuyun's shoulder and asked in a low voice, "What the hell is the human race doing? Why are they fighting among themselves?"

Yujun also didn't understand.

"Uncle, if you ask me, who should I ask?!"

"..."

"..."

The two looked at each other.

The demons are a little confused about what the humans are doing.

An official from the Ministry of Industry coughed lightly and asked, "How can you...if you can't even see the people...of course, you can use scouts to determine the enemy's movements, and then fire all your cannons, but this can't be considered accurate, right?"

Firepower coverage depends on equivalent, not accuracy.

There is nothing wrong with this logic.

Pan Manman said, "Sir, take a look at this picture of mine. It shows the hypothetical flight path of the artillery shells. As long as we find the right angle, we can hit the enemy beyond the visual range."

"You mean, the gunner needs to prepare a gun ruler?"

"Yes."

"..."

The people in the Ministry of Industry were stunned.

At this moment, Li Qingcha spoke up.

"Papa, there are big, very big problems with the picture you drew."

Pan Manman was nicknamed "Pa Pa" because she spoke as slowly as a turtle, which was very similar to her name.

She was a little surprised.

"But this is from 'Han Jia Yuan Di'..."

"Ah this..."

Li Qingcha had a helpless look on his face, thinking that he had just casually compiled an exercise book, but it turned out to be so unlucky that so many troubles had occurred.

“The map was useless and the gunners couldn’t understand it,” she said.

Pan Manman was puzzled.

"Why? This is what you taught me, and the curve is drawn according to the method you gave me."

"Then you should have noticed that when I was teaching you, I often mentioned the words 'ideal situation'. In reality, the trajectory of each artillery shell is different."

"..."

Pan Manman didn't say anything, but her expression still seemed to be asking "Why?"

Li Qingcha coughed lightly and didn't want to explain more.

Unexpectedly, the officials from the Ministry of Industry kept chasing after him.

"Master Li, you are right. The trajectory of each artillery shell is different. But you also mentioned the so-called 'ideal situation'. What is the ideal situation?"

They acted as if they were humbly seeking advice.

Hey!

Fuck fuck fuck fuck fuck fuck fuck fuck fuck!

Li Qingcha felt like a thousand horses were galloping through his mind as he looked towards the Seventh Prince.

The Seventh Prince understood and looked at the sedan chair.

There was no movement from the sedan chair.

"..."

"..."

"..."

In this eerie yet peaceful silence, the strings of pots swung in a big circle, but in the end they did not fall to the ground, but returned to Li Qingcha's back.

Li Qingcha said helplessly: "If you want to understand the ideal situation, you still have to explain the current situation. What causes the current situation that the trajectory of each artillery shell is different?"

The atmosphere at the scene became a little strange.

Everyone seemed to be listening to a lecture.

Li Hulun couldn't help but ask Yuyun again: "What on earth are the human race doing?"

Yujun's answer remained unchanged.

"Uncle, if you ask me, who should I ask?!"

The two of them were even more confused.

Chapter 490 Be careful of Li Qingcha!

On foot.

The emperor couldn't help laughing.

"Heh, Li Qingcha is shooting himself in the foot~"

He wasn't worried at all.

As long as one looks at the confused expressions on the monsters' faces, one will know that no matter what Li Qingcha says, even if it means undermining his own plans, the monsters cannot say anything to make things difficult for him.

Anyone who has watched "Han Jia Yuan Di" will reach a consensus -

Friendships can fade, love can fade, difficulties can make people suffer, and life can make people surrender, but the contents of books such as mathematics, physics, geography, and chemistry will never.

Because, if you can't do it, you can't do it.

The current state of the demon tribe is a perfect reflection of these six words. They will not make things difficult for Pan Manman.

No means no.

So let Li Qingcha go ahead and talk, maybe he can confuse the other party.

The emperor stretched himself.

"I didn't expect this essay test to be so interesting. It's much more interesting than the palace examination."

He turned to the overseer.

"Does the supervisor think that an artillery strike beyond visual range is possible?"

The supervisor nodded solemnly.

"possible."

"why?"

"Because since Li Qingcha said that, it proves that there is indeed some kind of 'ideal situation' that can be achieved, but the reality we are in now cannot be achieved yet."

The muscles on the emperor's face twitched.

I didn't expect the Supervisor to say such baseless words. The only basis for his words was his trust in Li Qingcha.

Emmmm......

Is this kid really that amazing?

The emperor sat up straight.

"Listen."

Everyone in the sedan chair listened attentively.

The square at Liubukou was very quiet, with only Li Qingcha's voice.

"The trajectory of each artillery shell is different. It's easy to explain because the manufacturing technology of the artillery is not up to standard."

The senior officials in the Ministry of Industry did not like to hear this.

"Master Li, you are also taking things for granted."

"Really? Are there any standards for the caliber, projectile, and length of our Daxia artillery?"

"Have."

“Can it be manufactured strictly according to the standards?”

"It can definitely be done... Well... There are some minor differences, Chief Li, you can't expect all the artillery to be the same, right? That's unrealistic..."

The officials from the Ministry of Industry looked at Li Qingcha and obviously thought that Li Qingcha was daydreaming.

Li Qingcha shook his head.

"It is this slight difference that leads to huge differences in the trajectory of the shells. In addition, there are even cases where the gunpowder standards are different. In addition, in actual combat, the artillery is not on flat ground, making it extremely difficult for the gunners to operate the artillery according to the angle."

Everyone in the Ministry of Industry looked at each other in bewilderment.

What I just said may make some sense, but it is only theoretical.

It is difficult for them to imagine that such a small difference can lead to such a big difference, which goes against both intuition and experience.

Someone said, "Master Li, you need to explain it clearly. You can't be so unclear."

Li Qingcha had expected this to happen.

She explained: "My Lords, please think about this. How do the artillerymen of the Great Xia Army operate the artillery now? Is it... um... something like, how many steps can be fired if the gun is raised one inch, how many steps can be fired if the gun is raised two inches, etc.?"

Everyone in the Ministry of Industry nodded.

"Yes."

"Isn't it the best evidence that every gun has to be explored in this way?"

"This……"

"An imperfect spherical shell, loosely packed in a nearly cylindrical barrel. Except for firing at close range, the shells fired in other situations are distributed around the target without any pattern. Can such artillery still be called standard?"

The officials of the Ministry of Industry noticed Li Qingcha's choice of words.

Imperfect spherical shells,

Loosely packed in

A barrel that is approximately cylindrical.

There is no regular distribution.

……

For a standard artillery piece, the situation should be exactly the opposite of these terms.

Li Qingcha said, "Paipa, do you understand? Don't think you can get everything at once. Now we have to rely on blindly to hit targets within visual range, and you are thinking of hitting targets outside visual range?"

Pan Manman seemed to have been hit by something beyond her visual range, and she looked a little depressed.

"But my gun ruler should be useful."

"Look, you said it yourself, that's just a 'should'. Before the problem of standard artillery is solved, gunners would rather trust their own eyes and experience than the gun gauge."

"Well...I understand."

Pan Manman lowered her head and stepped off the stage in frustration.

Except for the officials from the Ministry of Industry who were still thinking, everyone else had dumbfounded expressions.

Σ(⊙▽⊙"a

What does Li Qingcha mean?

Is it true that there are people who have taken the principles of fairness, justice and openness to heart, are selfless and angrily criticize their own candidates?
