He knew all the numbers, but when they were put together, and with some symbols he had never seen before, he was confused, but he knew that it was a very profound thing.

"I haven't seen it, it's arithmetic." Qin Rong said.

"Arithmetic, is there still this science?" Pei Chenzhou saw it for the first time, and he felt very novel.

"Yes, the examiners are divided into literature and arithmetic, and the officials of arithmetic are mainly specialized in water conservancy and engineering, without their detailed actuarial calculations, bridges and embankments, there will be no stable structure, and the scope of literature is wide, so the main test is literature."

Pei Chenzhou understood now, he looked at Qin Rong, his eyes were full of admiration and admiration, "Girl Rong, how can you do anything?" ”

And it's a complex science.

"I, there are many things I will do, you will know later." Qin Rong winked at him mysteriously.

The watery eyes blinked, as if a butterfly was flying, and Pei Chenzhou's eyes were deep.

Yes, she is his, all she has, everything she has, he will experience, and the thought of this fact makes him faintly excited.

Hearing a sound of rustling footsteps, Qin Rong looked back and saw that Shao Fengting had come with a few soldiers, all of whom were holding hoes and shovels in their hands.

"Brother Shao, are you here to help too?" She said politely.

"Well, I heard that you are going to dig a big charcoal kiln, and I thought that the amount of work is large, so I will bring a few people to help you." Shao Fengting saw that her attitude was lukewarm, and his heart was slightly cold.

"Thank you, when the digging is completed, my mother and I will treat everyone well." Qin Rong said.

Qin Rong took the straw paper and was about to make a mark.

Shao Fengting was stunned when he saw the content on the papyrus, "This is arithmetic?" ”

"Yes, Brother Shao, do you understand?" Qin Rong said.

"I can understand it, but I didn't expect that you are still so proficient in arithmetic, this one next to me, Xiao Cheng, he is a student of arithmetic, but he is one of the examiners who is off the list, but he still knows the basic arithmetic principles thoroughly, I originally wanted to dig a charcoal kiln from the inside, if the size is not grasped well, there may be a risk of collapse, so let him follow, give you a calculation, since you know arithmetic, it will save this matter."

The soldier named Xiao Cheng stepped forward and nodded at Qin Rong, "Miss Qin, can you show me the arithmetic you use." ”

Qin Rong knew that he was looking at her and was right.

She generously handed over the papyrus.

Xiao Cheng carefully browsed it, and there was a look of surprise on his face, "The result is the same as mine, but the rules used are different, and Miss Qin's use seems to be much more concise." ”

Arithmetic uses simple rules to calculate the results that would otherwise require complex calculations, saving time and energy, which has always been a problem that arithmeticians are keen to discuss, but he did not expect to see it here.

"Well, I don't like trouble." Of course, Qin Rong knew that ancient arithmetic was not easy to use, it was bloated, and it was unscientific, and it was easy to make mistakes, and many bridges and river embankments collapsed in ancient times, because of the inaccuracy of arithmetic, many Western arithmetic principles were introduced in modern times, scientific and concise, and many originally complex engineering calculations were introduced with only a few formulas.

"But where did these methods come from, Miss Qin, can you teach me?" Xiao Cheng looked at him with enthusiasm, with admiration, there was such a strange woman in the world, they originally thought that Second Lieutenant Shao's pursuit of Miss Qin was to lower his value, but now it seems that Miss Qin is fully worthy.

Qin Rong felt a little sorry when she heard that he had sent a famous Sun Shan, but she was now teaching three students, and if she taught one more, it would take a lot of energy, and compared to literature, arithmetic was much more difficult, and every step had to be explained many times.

And there is another problem with this, even if she wants to teach, it will not work at all.

She said, "The method I use is not in the regular books, and the examination needs to be calculated according to the steps in the prescribed books, if you use the method and come to the same conclusion, what do you think the examiner will think?" ”

Xiao Cheng fell silent, "This...... It seems that I don't think it's right, but looking at your calculations, I think your method is much better, concise and time-saving, so I want to learn. ”

Qin Rong shook his head, "In this case, the examiner will think that you are opportunistic and cheating, because he can't understand the calculation process, and he hasn't been in contact with it, but you have studied for a long time, even if you explain it to him, it is impossible for him to understand it for a while, and he will even get angry, which is likely to cause you to never be able to take the exam again." ”

"Ahh Xiao Cheng was frightened at this moment, and secretly poked and poked a shudder, but he had to admit that Qin Rong was right, "That's the truth, fortunately, Miss Qin, you reminded me, then I won't learn it, it's just that I can't use these methods, it's still a little regrettable." ”

Qin Rong smiled, "That's it, when you get in, I'll give you the formula and the algorithm, you can use it when you calculate the project, no one else can see it anyway, and my method will make the bridge and embankment more stable, as long as you can get in, you will definitely have a bright future." ”

She didn't say it too clearly, but Xiao Cheng completely understood, throughout the ages, there have been many arithmetic officials, just because the arithmetic project went wrong, the dismissal of the dismissed officials, the exiled exiles, and even the Shatou ones, if the project he is responsible for is stable, he can be completely successful.

The fifteen-year-old boy was originally discouraged by the failure of the last time, but at this moment, his chest burned with pride, "Well, I will continue to take the exam until the day I pass the exam, and when the time comes, I hope that Miss Qin will not forget what you said, and I will also repay you." ”

Qin Rong said, "Okay, if you invite me to eat a few delicious meals, I will be satisfied." ”

Shao Fengting patted Xiao Cheng's shoulder, "Boy, come on, take care of you." ”

"Hmm." Xiao Cheng raised his head and held his chest high, "I will definitely be able to be admitted next year." ”

Within the range marked by Qin Rong, everyone waved their hoes to excavate, although it was cold in winter, but they were in full swing, digging the soil, pouring the soil.

Qin Rong pondered, with a few more aids, he could dig up within this day.

She glanced at Pei Chenzhou's face, he was very calm, and he was not annoyed by Shao Fengting's arrival.

He is now more and more calm, because he believes that he and Rong Yatou are heart-to-heart, they can only belong to each other, no one can threaten them, Rong Yatou is so smart and capable, there will be men who fall in love with her in the future, he can't be angry with everyone.

As long as they are heart-to-heart, everyone else will always be outsiders, and with this firm belief in his heart, he is not afraid of anything.

The two of them are digging in one place and working together, which is also a kind of warmth, a kind of companionship, what flows silently between the two, that kind of peculiar feeling, which is only between two lovers, wonderful.

After digging for a while, Pei Chenzhou said, "Rong girl, you go and rest for a while, and I'll leave it here." ”

Although she is not as thin as before, but has grown into a normal figure, he still feels sorry for her because she is still young.

Qin Rong smiled, "Everyone is digging, where am I embarrassed to rest." ”

However, she remembered that she couldn't let the family be busy here, "I'll go back and cook some porridge for everyone to eat, replenish my strength, and have a good meal in the evening." ”

When we heard that there was something to eat, everyone was more energetic.

Vice General Lu came back from hunting pig food, and also found a hoe to dig the ground together, and also specially picked the land around Wan's side.

"I look at it and don't think you're digging the ground." Adjutant General Lu said.

"It's not like digging the ground, what does it look like?" Wan asked.

"Your strength and posture in digging the ground are different from other croppers who dig in the soil, and you are more like a person who has learned martial arts."

Wan Shi was slightly stunned for a moment, and then smiled, "Even digging the ground can make you see the doorway, it's not easy." ”

"Is what I'm saying true?" Vice General Lu lowered his voice and approached Wan's with bright eyes.

Wan Shi felt an indescribable pressure and glanced at the man, "Jing nonsense, do you think I look like a trained family?" ”

"It doesn't matter if it's true, I'm not afraid of being beaten by you." Vice Admiral Lu laughed heartily.

In fact, he had already seen that Wan was not a simple woman, and she appeared here for a purpose.

But that doesn't stop him from liking her.

"You're not afraid that I'll really hit you?" Wan was a little surprised.

"Don't be afraid, firstly, you are a reasonable person, secondly, I will be good to you, you have no reason to beat me."

Wan Shi glanced at him with disgust, "It turns out that you are a poor mouth." ”

"No, it's definitely from the heart." Vice General Lu quickly stopped digging the ground, raised his finger and swore.

Wan Shi was amused by him like this, but in his heart he had other thoughts, which should be said to be a kind of emotion.

Even if the man is good to her, so what?

She always has to pick a time to tell Vice General Lu that her mission doesn't know when it will end, and she doesn't want to delay others.
