Drive a RV and go farming in ancient times.

Gu Huanxi got off the car and saw that not far away, a small classroom on the deserted road was still in full swing. There were roughly two groups of people. One group was Xu Changbai, who was teaching literacy. They were almost all children and had no textbooks. Without paper or pen, Xu Changbai wrote on the ground, and the children surrounding him also took branches to draw gourds and gourds.

The other group of people are slightly older and are following Liu Xiu in literature and arithmetic. They are hoping to find a job in the future. Being able to calculate accounts will give them an advantage.

Gu Huanxi looked away and saw Gu Xiaoyu sitting alone in a chair reading a book. He walked over and asked, "Xiaoyu, why didn't you follow me?"

Gu Xiaoyu raised his head, glanced at the place where the children gathered to study, and said with a complicated expression, "My son knows everything my two uncles taught me."

Hearing this, Gu Huanxi couldn't help but be surprised, "Have you ever learned arithmetic?"

Whether it is her understanding of ancient times or the memory of the original owner, today's scholars do not pay much attention to arithmetic. In the previous imperial examinations, arithmetic was not included. Nowadays, although it is added to the official recruitment in the imperial court, the proportion is very small. People will still focus their main energy on the Four Books and Five Classics. Some people even classify arithmetic as a minor thing and look down upon it in words. Therefore, those who seriously study arithmetic, except those who really like it, just want to be accountants, or It's a merchant.

Gu Xiaoyu nodded, "Yes, I have learned a little bit of arithmetic in Chapter 9."

Gu Huanxi became interested and asked, "Will I test you?"

She majored in accounting in her previous life, so mathematics was not a problem. When she was free, she also read some of the more famous ancient arithmetic classics, such as "Zhou Bi Suan Jing", "Haidao Suan Jing", "Sun Zi Suan Jing" Sutra", and of course the most famous "Nine Chapters on Arithmetic".

Gu Xiaoyu would not refuse, and was even a little eager to give it a try.

Gu Huanxi asked him what he had learned. After knowing what he had learned, he wrote a few questions on a white paper with charcoal and gave it to him to do.

Gu Xiaoyu also used charcoal to answer, but he was not skilled in using it and his writing seemed a bit awkward. However, his speed in answering the questions was not slow, and his answers were all correct.

Gu Huanxi drank tea slowly and watched him answer the questions calmly. His calculation method was nothing special, but when he wrote the numbers, his gestures were very natural.

That's right, thanks to the gift of the founding emperor, Arabic numerals have now appeared, especially among the people. People who have never read books use numbers when they want to keep accounts because they are convenient and simple. However, those who are serious scholars are a little bit opposed to it, but they are still used to it. The use of writing was also required in the imperial examinations, probably because they were afraid that the numbers would be easily altered. As for the account books, it depended on the merchant's intention. Most of them were two in parallel. This is similar to the accounting in later generations.

"Well done!" Gu Huanxi praised without hesitation, "The answers are all correct."

The corners of Gu Xiaoyu's mouth curled up inconspicuously, and it flashed past.

"Can I give you a few more questions to try?"

"it is good……"

This time, the questions asked by Gu Huanxi were a little more difficult. Gu Xiaoyu's speed in solving the questions was obviously slowed down. However, as long as the answers he wrote were correct, by the last question, he frowned and thought hard. After a while, he hesitated to write, his face full of uncertainty.

Gu Huanxi raised his eyebrows, "Do you still want to change it?"

Hearing this, Gu Xiaoyu looked more and more hesitant and said tentatively, "Then let me think about it again, son?"

Gu Huanxi raised the corners of her lips, "Okay."

So, Gu Xiaoyu thought hard for a while, repeated the calculation several times, and then crossed out the number just now and changed it to something else.

Seeing this, Gu Huanxi asked again, "Do you want to change it yet?"

This time, Gu Xiaoyu shook his head.

Gu Huanxi asked again, "Are you sure this is the answer?"

Gu Xiaoyu became uneasy due to her repeated questions, but she still nodded stiffly, "That's it, I won't change it anymore."

Gu Huanxi smiled slightly, "That's a pity, this answer is wrong..." At this point, she paused and saw disappointment flash across his face before continuing, "But what's even more pity is that the initial The answer you crossed out is the correct one."

Gu Xiaoyu, "..."

At this moment, he was no longer disappointed, but regretful and unwilling.

Gu Huanxi asked, "Are you regretful? Regret that you didn't persist to the end. My few words easily affected your own judgment. Although this question was difficult, you were still able to get the correct answer, but in the end you revised it wrong. , because my words made you question and become unconfident."

Gu Xiaoyu was ashamed.

Gu Huanxi touched his head, "Mom is not criticizing you, but letting you understand a truth through this incident. Sometimes, the result is correct if you stick to your original intention and don't deviate from it because of interference from others. Only if you don’t forget your original intention can you always succeed, do you understand?”

Gu Xiaoyu nodded solemnly. This incident and these words would occupy an unbreakable position in his future life. His original intention as a child and his youthful ambition have never changed despite numerous tests, temptations, and sufferings. , and finally move towards the life he wants.

When they set off again in the afternoon, the Yao family's carriages and horses also followed. Originally, the Yao family wanted to pay a lot of money to hire Dr. Jiao to go with them alone. The speed was not only fast, but the road was also comfortable. The villagers separated, and in desperation, the Yao family gave in and reluctantly walked with the victims.

Who says it’s hard to find a miracle doctor?

In this way, the team has grown a lot. The Yao family is naturally at the front, with horses and mules, and there are five big and three thick bodyguards who are clearing the way to intimidate. The overall momentum of the team is suddenly much higher. Speaking of three or two refugees, even ordinary people who have not yet started to flee will stay away from them when they see them.

This arrangement saved a lot of trouble. The villagers followed behind and couldn't help but feel at ease. It was easy to enjoy the shade with their backs against the big trees.

But Xu Huaiyi was a little annoyed, not because the Yao family took away his job of leading the way, but because after the Yao family joined in, some things became very passive, such as the speed of travel, such as finding a place to bury the pot to make rice. The Yao family will not consider the opinions of their Xujiacun, and will just make the decision for them as a matter of course.

So when they stopped to rest midway, Xu Huaiyi found Village Chief Xu and reminded him, "We still have to find a suitable opportunity to separate from the Yao family as soon as possible."

Village Chief Xu was stunned and asked puzzledly, "Why? Although it is a little inconvenient to follow them, it is safe and secure. They are escorted by bodyguards, so no one dares to attack us on the way. The advantages outweigh the disadvantages." , this is feasible..."

Xu Huaiyi said meaningfully, "Good luck and misfortune are interdependent. Uncle village chief, you only saw the shock that the Yao family's bodyguards brought to the victims along the way, but you forgot about the grain that the Yao family's mule carts were carrying. We will be coveted by so many robbers and bandits. When they come to rob us, will the bodyguards protect us? We will only become a victim of disaster. "

Hearing this, Village Chief Xu's expression suddenly changed, and cold sweat broke out on his spine, "Yes, you are right, you can't just look at the benefits in front of you and lose sight of the danger. Huaiyi, thank you for reminding me, Otherwise, uncle will make a big mistake..."
