……

A group of mathematicians, a group of engineers, are arguing and pushing around, and it seems that they are going to start a fight at any moment.

The people in the back have already rolled up their sleeves.

In such a noisy environment, Cheng Lao's demon is actually there, what a miracle!

He sat helplessly beside him, watching them quarrel and fight there, without stopping them at all.

This is not in line with the character of the devil?

Can the Adversary allow others to suffer in his presence?

But something like this happened. The old devil sat there quietly, watching them argue and push.

What is even more strange is that Li Chengqian did not feel a sense of disobedience.

Except for Cheng Lao, who did not move, the soldiers did not dare to step forward.

They stood on the periphery, as if they were going to come up and stop them. That's right, they have that heart, and it is precisely because of this expression that Li Chengqian can see that they are not watching, but really want to go up and help.

But I just didn't dare to go up.

"What's going on?" Li Chengqian stepped forward and asked.

When Cheng Laoxiang saw Li Chengqian, it was like seeing his father, so he quickly stood up and walked over to him: "Oh, Your Highness, you're here!" ”

He glanced outside and said, "Is Your Highness riding the old mare of the Qin family again?" ”

He had seen how slow it was when Li Chengqian was walking on a pony.

At this time, he was waiting for Li Chengqian to come over to relieve the siege, and when he saw that it had only arrived now, he guessed it, so he hated Uncle Ma, and when he said it, he added the old mare of the Qin family!

"Yes. Don't talk about that yet. What's wrong with this, you don't pull it apart either? Li Chengqian pointed with his hand.

Cheng Lao is hard to say. said: "I Lao Cheng knows today, and I didn't accept those sour pens before." Because I think that's what they are, simple things are complicated. When I met these two groups of people today, I realized that I really couldn't understand it! ”

He pointed and was still arguing, so noisy that he didn't even know that Li Chengqian was coming.

said: "Your Highness, these two groups of people were taught by you, you are going to pull them away." ”

Li Chengqian still didn't understand what he was saying.

But I had to walk over and ask, "It's all quiet, what's wrong?" Didn't work inside and quarreled outside? ”

"Quiet!"

"Shut up!"

Both gangs yelled.

Some people were distracted and turned their heads, but when they saw Li Chengqian, they were stunned. Just now they were actually drinking a prince.

As one person was stunned, the others also sensed that something was wrong, so they also turned their heads to look.

Stunned.

Collective rigidity.

They were all stunned.

Because these two gangs of quarrels were the main source of the noise of this quarrel, as soon as they were quiet, the whole powder bureau fell silent.

For a while, the needle drop can be heard!

The focus of all. It's all on Li Chengqian.

"Ahem." Li Chengqian coughed with a sense of accomplishment, and then asked, "...... you?"

As soon as he spoke, the people who drank the prince just now woke up and hurriedly knelt down to apologize.

"Get up. Why are you arguing? Li Chengqian shouted.

The elementary school mathematician on the side of the little white face said: "Your Highness, these wild people are too rude!" ”

This wild road's statement. It means that they engineers have no mentorship and have not read many books. The gunpowder also had to be groped for slowly.

The wild roaders were not convinced when they heard this, and retorted: "Your Highness." It's these people who eat white rice are too unreasonable! ”

Eating white rice means that they will not discover it for themselves, but will only use the knowledge taught by others.

Li Chengqian sorted it out for a while before he realized that there was a difference between "etiquette" and "reason" between these two groups. The people who eat white rice think that Ye Luzi does not follow their advice and is rude. Ye Luzi thinks that the person who eats white rice does not speak according to the facts, which is unreasonable.

With such a detour, it's no wonder that a demon like Cheng Laoxiang can't take care of it.

He glanced at Cheng Lao Xiang sympathetically, then turned around and asked:

"And what exactly are you guys doing?"

The man who ate the rice stood up and said: "Your Highness, we have different opinions because of a difficulty, at the beginning, this brother Tai and the wild road over there were discussing, but he thought that the result we calculated was not right, of course we did not agree, so other people came out to reason with him, and as a result, all the wild roads on their side came out, and we can't let them insult the mathematical knowledge that His Highness taught us, so I came out to reason with them to the end!" ”

After this man finished speaking, he went down to rest, and then the second one who ate white rice stood up, that is, the one who was the first to fight with Ye Luzi.

He said, "Your Highness, between two locations, a straight line is the shortest distance. In this way, the distance between the launch point and the target can be calculated, but these sub-wild people said no, saying that if the road is uneven, there are mountains and water, then the ups and downs, isn't it that there are more measured roads. It's not the same as the theory at all, and we don't think they're right. They say we're short-sighted. ”

Li Chengqian's eyebrows jumped. This kid has read a lot and doesn't know how to practice!

The wild roaders over there laughed.

A very arrogant wild man stood up and ate more salt than the one who ate white rice over there.

But his words were not treated well by Li Chengqian.

The mathematical theory is correct, but that's on the same plane. In fact, there are geographical reasons, which make the road ups and downs, and there are changes, and even the launch point, which is one high and one low with the target point, not on the same level, if this is calculated by mathematics, it requires more advanced mathematics to calculate.

However, this is not something that Li Chengqian can answer.

And that's not the end of the question. Eat white rice and say:

"We use the angle to calculate, from the distance of XX meters, launch the rocket to the whip target, with the XX angle, with XX gunpowder, you can hit. That's the best way to figure it out. But Ye Luzi even said that they used visual inspection, thinking that this was not enough, the angle should be half higher, and the amount of gunpowder should be two-thirds smaller, which is better. But it really doesn't make sense! ”

"I've all launched them, why can't they?" Ye Luzi won't let them say enough on their own, hummed.

Li Chengqian's brows jumped again.

What Li Chengqian said about eating white rice, he first denied him theoretically. The word best is misused.

Now the mathematics knowledge he teaches them, that is, the primary school is saturated, and the junior high school is half small, where can such a amount of knowledge be calculated to be really the best way. It's the computer of the future!

He had a parabola in his head, one point to another, and he could draw many parabolas.

And the line for eating rice is a matter of a lower height.

In this way, when the arrow is flying, it is very close to the ground.

What Ye Luzi proposed was to let the arrow fly high, and then land on the target.

When it falls, it is not pushed by gunpowder, so the amount of gunpowder is smaller.
