Although Xu Guangqi's roots are traditional scholars, he does not lack a studious heart.

In the exchanges with Western missionaries, Xu Guangqi had a heart to serve the country and carefully studied the most advanced technology in the West at that time.

After completing his studies, he continued to play at the imperial court and begged the imperial court to adopt it.

However, like a mud cow entering the sea, there is no response.

In the end, he had no choice but to retreat, write books and open a museum to accept apprentices.

He wrote works such as "The Complete Book of Agricultural Administration" and taught such high-ranking disciples as Sun Yuanhua.

Now, I saw the author of Wu Beizhi again, Mao Yuanyi was present.

Xu Guangqi was also interested, and decided to operate it himself and teach the students and Mao Yuanyi a lesson on the spot.

I saw that he used paper and pen to draw a ballistic trajectory on the spot according to the geometry and ballistics he had studied. Then adjust the cannon body and aim at the big tree in the distance.

Reload, ignition, fire!

Rumble!

There was a loud bang, and the tree exploded.

The soldiers on the scene were all shocked, this is too accurate!

"A teacher is a teacher, it's amazing!"

Sun Yuanhua said excitedly.

Xu Guangqi said: "Artillery shooting technology is not difficult to say, and it is not easy to say that it is simple. If you know the most basic subject knowledge and then apply it after mastering it, you can improve the accuracy of shooting. ”

"How long does it take to learn this?"

Mao Yuanyi asked curiously.

"Look at the talent, but also look at the foundation. Chu Yang studied geometry with me, and it was no problem for about a month to base it. ”

Xu Guangqi thought for a while and said, "If you don't have a mathematical foundation, it's difficult. Maybe you won't be able to learn it in your lifetime. ”

So long!

Sun Yuanhua and Mao Yuanyi glanced at each other, and both lowered their heads in thought.

Time waits for no one, seeing that winter is coming, the day when the slave soldiers go south, you can count with your fingers, where is the time.

Even if they learned it, those Ming soldiers didn't have time to teach.

"There's another way!"

Xu Guangqi said, "It is to directly hire the Portuguese as instructors, and it depends on whether Yang Chengying is willing or not." ”

That's a good idea.

As soon as the two were combined, Sun Yuanhua continued to accompany Xu Guangqi around, while Mao Yuanyi temporarily left and went to the Shuai tent to find Yang Chengying.

When Mao Yuanyi arrived, Yang Chengying was not in the tent.

When I asked the guards who stayed behind, I learned that the general had something to do and would come back in the evening.

Mao Yuanyi had no choice but to return and come back in the evening.

So what did Yang Chengying do?

It turned out that the people did not want to stay in Jinzhou and return to their homeland, although Yang Chengying verbally said that he was nothing, he cared very much in his heart.

After all, Fan Wencheng had just taken over not long ago, so it was not good to be too harsh on him.

But Yang Chengying wanted to know some about the situation, so he changed into people's clothes, took Geng Zhongming, Kong Youde and other guards, and went to the residential area for a private visit.

He chose an area far away from Xintun, rode his horse for a while, and then dismounted and walked for a while.

People's houses can be seen everywhere.

Yang Chengying picked one at random, stood at the door of the small courtyard, and gently knocked on the door of the courtyard made of bamboo.

"Excuse me, is anyone home?" Yang Chengying asked loudly.

"Who?"

An old man walked out of the house and saw Yang Chengying with several strong guys, and he was a little worried.

Yang Chengying smiled and opened his mouth to dispel his doubts: "Old man, we are the inspectors sent by Mr. Fan, and we are ordered to solve the conflict in the neighborhood. ”

As he spoke, he took out a proclamation stamped with the official seal of the yamen and showed it to the old man through the broken courtyard gate.

The old man can't read anyway, and he can't understand it, but he knows the official seal.

Immediately, he opened the door with a smile: "It turned out to be the official sent from above, please don't blame the old man for his bad eyes and didn't recognize it." ”

"It's okay, we're just going to sit outside." Yang Chengying said with a smile.

"Okay."

The old man led them to the courtyard, and then moved a chair out of the house, wiped it with his sleeve, and gave it to Yang Chengying to sit on.

He himself chose to squat.

Yang Chengying just sat down, and when he looked at him like this, he instinctively stood up.

The old man was taken aback.

"You sit, I'll squat and ask you."

Yang Chengying helped the old man and asked him to sit down, while he squatted in front of him.

The old man was flattered: "The official is the most polite I have ever seen." The officials who came before were all sitting, and we were squatting. ”

Hearing the old man boast of his own commander, Geng Zhongming and the others showed smiles on their faces one by one.

Yang Chengying's face was a little ugly.

But in a flash, he asked very gently: "Mr. Fan asked me to ask you, is there any one who collects grain and takes the opportunity to ask you for money?" ”

"No, no......" The old man hurriedly waved his hand, full of denial, for fear of getting a little edge.

Yang Chengying frowned and looked around, and ordered: "You all wait for me outside the courtyard, and you are not allowed to eavesdrop on our conversation." ”

"Yes."

Geng Zhongming and others left one after another.

In the courtyard, only Yang Chengying and Lao Han were left.

Yang Chengying said with a sincere face: "Old man, don't worry, this is a very secret visit, and the purpose is also to eradicate those pests, you just have to tell the truth." ”

"Can you really say anything?"

The old man was still a little scared.

"Of course. Whoever wants to find fault with you, I will be the first to not let them go. ”

Yang Chengying said with an oath.

"Okay, for the sake of the family, I said."

The old man took a deep breath, as if he had made some important decision.

Yang Chengying nodded.

The old man whispered: "I think that there is a problem with that thing that collects grain, and there will be less grain if you kick it twice." When it was less, we had to carry food to make up for it. ”

It turns out that this is the case, dare to use your hands and feet on the grain collection utensils!

Yang Chengying's face became ugly.

The old man said again: "Of course." Compared to Jianyu, the general has been very good to us. Houses and land, farm tools, and seeds. ”

"You show me the farming tools, and I'll see if there's any change." Yang Chengying said.

"There was a handful of broken ones, and the good ones were taken to the fields by my son and daughter-in-law."

"Bad ones are fine."

"Wait a minute, I'll go get it."

The old man immediately got up, and soon after entering the house, he took out this missing hoe and handed it to Yang Chengying.

Yang Chengying took the hoe and lifted it, the weight didn't seem to have become lighter, and then looked at the gap. Nothing was a problem.

He let out a sigh of relief, and finally there was no problem in this regard.

"Old man, in addition to the hoe, I remember a sickle, a hatchet, and a nail rake, right?"

Yang Chengying asked.

The sickle is used to cut grass and feed poultry, the wood knife is used to chop wood, and the nail rake is used to dig ditches and raise grass, which are all very practical agricultural tools.

are among the distributions.

"Yes, but there is no rake." Old man said.

"No, or you don't." Yang Chengying hurriedly asked.

"Some of them are distributed at home, some of them are bought at home, but I don't have them at home."

"What about your chief? I want to ask him. ”

Yang Chengying asked.

According to Yang Chengying's tuntian system, every ten households are one tun, and there is a tun chief. Receiving some rice grain every month is considered a salary.

The old man paused for a moment, and then said in surprise: "I am the tun chief." ”

Yang Chengying was stunned.
