The book has no strength, the female supporting role just wants to survive

The accountant was a little hesitant. The woman seemed very confident, but after thinking about the hundred gold, he gritted his teeth and agreed.

"Does the shopkeeper have any objection?"

The shopkeeper had already noticed it when the accounting officer came out to stop them, but he pretended not to see it and chose to watch the fire from the other side of the river.

"I won't get involved in what's going on between you two."

Jiang Tunan nodded, and then said loudly,

"In this case, I would like everyone present to bear witness today."

How could the onlookers around miss such excitement? They all enthusiastically agreed to be witnesses.

"However, this competition should have a referee. Who will it be?"

Just as Xiao Mingxu was about to move forward, someone in the crowd recommended himself.

"I come!"

The visitor was an old man with wrinkles all over his face but bright eyes. He was wearing a simple satin dress.

The accountant was a little impatient, thinking that these young ladies were just troublesome.

The old man didn't care whether the two agreed or not, and walked between them to ask,

"How would you two like to compare?"

Jiang Tunan made a gesture of invitation to the accountant, indicating that he should speak first.

"There are three questions in total. In the first two rounds, you and I will each ask a question. If you answer the other person's question correctly, you will get one point. If the other person answers incorrectly or cannot answer your question, you will also get one point. In the third round..."

"Let me do it!"

The old man took over the conversation and actively recommended himself.

"you?"

The accountant looked at the old man in front of him and thought he seemed unreliable.

"I also learned some arithmetic when I was young, so you don't have to worry."

After the old man explained, the accountant reluctantly agreed that the winner could be decided in the first two rounds, and the last round was not important.

Jiang Tunan and the accountant wrote the questions on their own pieces of paper, folded them up and handed them to the old man, who then handed them to them.

The accountant opened the paper immediately after receiving Jiang Tunan's question, but Jiang Tunan opened it slowly.

Open the question, it says: There are pheasants and rabbits in the same cage, there are twenty-three heads on top and seventy-six legs on the bottom, how many pheasants and rabbits are there?

Jiang Tunan took one look and laughed out loud.

Ye Ruzhen: It’s over, Xiaonan has been driven crazy.

Xiao Mingxu also looked at Jiang Tunan worriedly.

After Jiang Tunan finished laughing, he picked up his pen and wrote down the answer. Just a chicken and a rabbit in the same cage, it was done in seconds!

Seeing that Jiang Tunan answered so quickly, the accountant thought that Jiang Tunan had given up. He sneered a few times and looked through Jiang Tunan's questions carefully.

But the further we looked, the worse the accountant's face looked, and sweat broke out slightly on his forehead.

The old man was curious when he saw Jiang Tunan moving so fast.

"You made a girl doll?"

Jiang Tunan nodded towards the old man and handed the question and the answer to him.

The old man opened the question and thought to himself, it turned out to be a question about pheasants and rabbits in the same cage. It was not difficult, but the girl was a little too fast. So the old man began to check Jiang Tunan's answer and found that it was also correct.

"This lady has answered correctly."

When these words came out, everyone was amazed. Only the accountant looked panicked.

"This is unfair. The premise of setting a question should be that you can figure it out yourself. You are deliberately giving me a difficult question to embarrass me!"

Jiang Tunan didn't indulge him either.

"Why? Just because you can't figure it out yourself, you think others can't figure it out either? Or, with your ability, you can only solve a chicken-and-rabbit-in-the-same-cage problem?"

Jiang Tunan was speechless.

"You are so old, but you still only know how to play chicken and rabbit in the same cage. You are really pitiful. I will give way to you."

The accountant was so angry that he could not speak. The old man was curious and walked to the accountant to see what question Jiang Tunan had asked.

On the paper was written in slightly sloppy handwriting: Now there are three bunches of top grain, two bunches of middle grain, and one bunch of bottom grain, which is 39 dou in weight; two bunches of top grain, three bunches of middle grain, and one bunch of bottom grain, which is 34 dou in weight; one bunch of top grain, two bunches of middle grain, and three bunches of bottom grain, which is 26 dou in weight. How much weight is there in one bunch of top, middle, and bottom grain?

(bing: bundle; he: general term for food crops)

The old man was a little surprised that this little girl could come up with questions. Xiao Mingxu and Ye Ruzhen also ran to the accounting office to see what questions Jiang Tunan had come up with.

Before Ye Ruxuan had time to finish reading, she felt dizzy.

"I don't recognize the two characters Bing and He anymore."

Xiao Mingxu was silently calculating in his mind.

"The accountant is right, girl, you have to come up with a problem that you can solve in order for it to count. Can you solve this problem?"

Jiang Tunan walked up to the old man and gave the answer.

"One bunch of top-grade rice is worth one-fourth of nine dou; one bunch of middle-grade rice is worth one-fourth of four dou; one bunch of bottom-grade rice is worth three-fourths of two dou."

This problem seems to have three unknowns, but it is actually a problem about a system of linear equations with two variables.

"Three sets of conditions, three unknowns. We only need to eliminate the lower grain first. By subtracting the first and second sets of conditions, we can get: the grain of one sheaf of upper grain minus the grain of one sheaf of middle grain equals five dou. Similarly, by the second and third sets of conditions, we can get: five sheafs of upper grain plus seven sheafs of middle grain equals seventy-six dou.

One sheaf of upper grain minus one sheaf of middle grain equals five dou, so seven sheafs of upper grain minus seven sheafs of middle grain equals thirty-five dou. Adding the two groups together, we get…”

"One bunch of top-grade rice is worth one-fourth of nine dou; one bunch of middle-grade rice is worth one-fourth of four dou; one bunch of bottom-grade rice is worth three-fourths of two dou."

Xiao Mingxu gave the answer, his eyes revealing undisguised admiration for Jiang Tunan.

"Wow! Xiaonan you are awesome!"

Ye Ruzhen clapped her hands in adoration, leading everyone around her to applaud as well.

Jiang Tunan: So this is the feeling of getting slapped in the face, it feels so good!!!

"Wonderful! Wonderful! Wonderful!"

The old man said "wonderful" three times in a row and read the question written by Jiang Tunan over and over again.

"Admit defeat, uncle!"

Although Jiang Tunan was happy, he did not forget the agreement he made with the accountant at the beginning.

"you!"

The accountant's face turned red and he stammered, unable to speak. Not only did he not earn a hundred gold, but he also lost his job.

No, he couldn't lose his job. If he didn't have this job, would he be left with nothing?

"Why, you don't keep your word?"

Jiang Tunan knew that he was reluctant, so he didn't give him a chance to speak, and kept asking,

"Everyone present here is a witness. You are not going to regret it, are you?"

The crowd followed suit and started to make noises.

"Yeah yeah!"

"A grown man can't afford to lose!"

"I'm willing to admit defeat!"

The accountant had no choice but to look to the shopkeeper for help.

The shopkeeper sighed helplessly and came out to persuade him.

"Miss, please give me some face and let this matter go."

"What face do you have? Are you talking about my face just now?"

The shopkeeper choked, wondering how could this girl be so unreasonable.

"Do you have to be so aggressive, girl? Sometimes being young and hot-tempered isn't a good thing. Listen to my advice. Take a step back and you'll have a bright future."

"Take a step back to open up the world?"

Jiang Tunan laughed a few times, his eyes sparkling.

"You retreat, I won't."
