102 Sun Hao stood there, and when he learned that the head of the regiment had given them a pencil and a piece of paper, he was very helpless, but in fact, he also knew in his heart that he was poor in eight ways, and many of these pencils were half-cut, and it was not easy for Lao Wang to get these!

"Okay, let's not talk nonsense, come on, first know the cannon, you need to know every part on the cannon, you need to know how many of these cannons need to be mobilized when they are fired!" Sun Hao said to those soldiers!

As soon as Sun Hao said it, a soldier was there with a pen and recorded it.

"These rote memorization, no need to record, I'll draw a drawing later, put it here, everyone read more and memorize more, this has to be recorded, so how will you learn in the future?" Sun Hao stood there and said to them.

"Yes!" When they heard it, they nodded immediately, and then Sun Hao made an introduction to them one by one.

When it was almost noon, some soldiers went to cook, so the soldiers ate first, while Sun Hao sat on the side of the artillery position, holding a pen and paper, and began to draw, and at the same time, thinking about how to teach them mathematics,

The trigonometric functions that artillery mainly learns, as well as parabolas, and more advanced mathematics, but these mathematical knowledge, in later generations, junior high school students can master,

However, let these people who have never read to learn to shoot artillery, and at the same time, they also have to conduct artillery reconnaissance in schools, this difficulty makes Sun Hao a headache!

"What are you up to?" Xiang Yan ran over and asked Sun Hao.

"Well, nothing?" Sun Hao heard it, shook his head and said!

"What is this?" Xiang Yan saw a lot of things written on Sun Hao's notebook that he didn't recognize, and immediately asked.

"What you're going to learn in the future, hey, that, go find Biaozi! Zi went back and told the regiment commander, let the regiment commander platoon a guard squad of soldiers come over, I need them to keep an eye on the devil's movements here, because I need to teach you to fire artillery here, no one can do it! Sun Hao said to Xiang Yan.

"Huh? No, just the rest of us, let's take 30 minutes to go over there and stare at it, no problem! Xiang Yan heard it and said to Sun Hao.

"You know a fart, in half an hour, you will be completely pulled down, and I will teach you a second time when the time comes?" Sun Hao sat there and spoke.

"Oh, too! I'll look for those! Xiang Yan heard it and nodded.

"Wait a minute, in addition, you send a squad of soldiers down, go to the river and everyone carry a bag of sand, and then everyone will make a piece of open land by themselves, since there is no book, a lot of calculations, can only be written on the ground with wooden sticks, so as to save paper!" Sun Hao said to Xiang Yan.

"Ah, good!" Xiang Yan heard it, nodded, and went down again,

And Sun Hao still continues to write textbooks there, and now he can only write simple textbooks, and Sun Hao doesn't know where to start teaching, so he can only use goal-oriented backwards, such as school parabola, what knowledge needs to be mastered first, step by step, and the same is true for trigonometric functions!

Therefore, Sun Hao sat there, racking his brains and thinking, and he didn't know how long it was, even when he was eating, Sun Hao didn't know what he was eating.

"Don't say it, the squad leader is amazing, I just went to see it, I can't understand any of the things written in that book, cultural people are cultural people!" Xiang Yan sat there, looking at Sun Hao, who was writing something in the distance, and said,

And the other fighters are now also building bunkers and simple houses, Sun Hao told those soldiers that they may need to stay here for a long time, and now the weather is still so cold, there is no place to shelter from the wind and cold, but no, so the soldiers are now doing it themselves.

"Squad leader, squad leader!" At this time, a soldier ran over and shouted at Sun Hao, Sun Hao heard it and turned his head to look over there.

"Devils, devils, devils are coming, devils have entered the county, a lot of vehicles!" The soldier panted and said to Sun Hao,

Sun Hao heard it, put down his notebook, took the telescope, and climbed to the top of the mountain, where he could also see the direction of the county, that is, it was farther than the previous observation point, but now Sun Hao is looking forward to the telescope, which is much better.

"Made, sure enough, it's here, a lot of vehicles!" Sun Hao looked at the road to the south, there were still a large number of devil military vehicles, and there were also many vehicles parked in the county.

"Squad leader, will they come out today?" The warrior asked Sun Hao.

"They won't come out, they came out to look for death, now the city wall over there is a hole everywhere, they need to make up for it, I guess Jiro Mizuhara must be here, for sure!" Sun Hao was lying there, holding a telescope and saying,

And at this time, Xiang Yan and the others also came up, and they were all lying over there.

"At night, I will teach you to fire the cannon, and when we go down first, I will teach the soldiers how to operate first, and then you will listen to my orders!" Sun Hao said to Xiang Yan.

"Uh-huh, good!" Xiang Yan said very excitedly when he heard that Sun Hao would fire at the county seat at night.

"Let's go, you go back to the front, tell the comrades in front of me, and keep an eye on the devils in the county!" Sun Hao said to the soldier who came to report the news.

"Yes!" When the warrior heard this, he immediately went down the mountain, and Sun Hao also came down from the mountain.

"All come here, all come here!" Sun Hao stood there and shouted, and the other soldiers heard it, and immediately put down their work and ran to Sun Hao's side.

"You came here to learn to shoot a cannon, but to learn to shoot a cannon, you need to have knowledge, you don't have it, it doesn't matter, I'll teach you.

However, now there are devils in the county, and you may not be able to learn how to fight accurately for a while, but you must be able to operate those operations, and now, I will tell you how to operate the cannon, that is, how to let him fight!

Let him fight first, and then let him fight accurately, this is the process of cultivating you, 6 people come up! Sun Hao stood there and shouted.

"I'm coming, I'm coming!" The other warriors immediately raised their hands, and everyone wanted to learn.

"Don't worry, everyone has to operate, they have to know!" Sun Hao stood there and said to them, Xiang Yan immediately ordered the six people in front of him to come over, Xiang Yan was also watching from the side, he wanted to take a look first,

And when Sun Hao saw them coming, he immediately arranged a position for them and instructed them one by one how to operate this position!

"Oh my God, is it so complicated to fire a cannon?" Xiang Yan saw Sun Hao guiding the movements of those fighters, and said in shock, and the other fighters also nodded.
