Chapter 870 Is this bullying the ancients?

The woman who spoke was Shi Qingning, the youngest daughter of Shi Yingcai, the head coach of Xijiang Camp. Xijiang Camp was not as large as the Northwest Camp, but it was the main force in resisting enemies in the southwest. Because of this relationship, Shi Qingning was a little unhappy with Bai Ruozhu.

Shi Qingning is the youngest child of Shi Yingcai, so she is particularly loved. She is also a bit arrogant and is considered a little bully in Jiangnan. Even Xu Panrui and the others do not dare to provoke her easily.

She really wanted to find trouble for Bai Ruozhu because she thought Bai Ruozhu was so brilliant. It happened that she had recently read some information in Hetuluo's book and found such a question. She even discussed it with her brothers and sisters, but everyone Haven't figured it out yet. When she thought about it, she felt a little proud and wanted to trouble Bai Ruozhu. Who knew that after she finished speaking, she saw a smile on Bai Ruozhu's lips.

"What's so difficult about this? I already know the answer, and I know that the sum of every three numbers is fifteen!" Bai Ruozhu said loudly.

The audience was in an uproar. After listening to Shi Qingning's question, everyone pondered it and found it really difficult. Not only did the sum of three horizontal rows and three vertical columns have to be the same, but also the two diagonals should be the same, which is eight sets of numbers. It all adds up to the same result. Is this possible?

What's even more surprising is that Bai Ruozhu already has the answer.

"What? How could it be so fast?" Shi Qingning asked in disbelief. If it were before, she might have laughed at Bai Ruozhu for bragging, but after seeing Bai Ruozhu get so many questions right, she didn't dare to look down on Bai Ruozhu. , otherwise the questions in Hetuluo's book would not have appeared as soon as they started.

Bai Ruozhu smiled, turned to the boy beside him and said, "Please help me move the table and banknotes here. I'll write it out for everyone to see."

The boy who was helping in the competition hall hurriedly moved the table to Bai Ruozhu, helped her spread out the paper, and put it on top with a paperweight.

At this time, the audience was very quiet. Everyone stared at Bai Ruozhu, wanting to see if she really knew the answer.

Bai Ruozhu drew a large nine-square grid on the paper, and then wrote nine numbers in Chinese characters. She almost wrote Arabic numerals out of habit, and people thought she was drawing talismans.

"Okay, let's see if they all add up to fifteen." Bai Ruozhu said, picking up the paper and hanging it on the fixed shelf next to the table.

Many people in the audience stood up in order to see more clearly. Everyone carefully added up the numbers and counted them, trying to find a row or column that did not add up to fifteen. Unfortunately, they were disappointed.

Bai Ruozhu saw that Shi Qingning was very serious about calculation and subconsciously raised her fingers. She almost stopped laughing. She thought to herself that this girl had to test her even if she wanted to do arithmetic.

But does this count as bullying the ancients?

Someone at the judges' table had already written down this answer, and the judges also expressed their admiration, saying that the question was well asked and the answer was even better.

"You're right, how could you count so quickly?" Shi Qingning's tone was much better at this moment, not as aggressive as before, but she was just looking at Bai Ruozhu curiously.

Bai Ruozhu smiled at her and said, "I have done this question before, so it can be considered a trick."

Shi Qingning was stunned for a moment, but soon laughed and said, "It's your ability to be able to do it. No one can know the questions in Hetuluo's book."

This time it was Bai Ruozhu's turn to be stunned. She had only done this question in her previous life when she was in the elementary school Mathematical Olympiad, and the same nine-square grid could also be filled with another set of numbers. Just follow this rule, but she didn't know that this question was in Dan. The Liang Kingdom is very rare, and it is still listed in the Hetuluo Book.

She simply chose not to speak, with a faint smile still on her face, looking a little enigmatic.

"But I'm not convinced by this alone. We're both not good at magic. Ask my accountant to give you another question." Shi Qingning said.

"Okay." Bai Ruozhu saw that a middle-aged man was sitting next to Shi Qingning, and he knew that she had said before that the audience would give her questions, so the young lady called the person in advance.

The accountant of the Shi family stood up, bowed respectfully to Bai Ruozhu, and said, "Miss Bai, here's a question."

Seeing that he was very respectful, Bai Ruozhu returned the greeting and said, "Please."

"The day before yesterday, the house purchased four carts of fruits and two carts of vegetables, which cost a total of twenty-six taels of silver. Yesterday, the house bought the same one cart of fruits and three carts of vegetables, which cost a total of fourteen taels of silver. May I ask? How much does a cart of melons and fruits cost? How much does a cart of vegetables cost?"

Shi Qingning was very happy after hearing this, and even gave the accounting clerk a thumbs up with a wink, meaning that the question was good and difficult.

Bai Ruozhu became more interested. There was a question about linear equations in two variables. She took a pen and quickly scratched the paper a few times, and quickly calculated the answer.

"A cart of fruits and melons costs five taels of silver, and a cart of vegetables costs three taels of silver." Bai Ruozhu said loudly.

The accountant's expression changed, "I didn't expect Miss Bai to figure out the answer so quickly. I'm not talented enough to pass Miss Bai's test."

Everyone calculated based on Bai Ruozhu's answer, and it turned out to be correct. However, if there is no answer, it would not be easy to calculate it so quickly.

Shi Qingning didn't blame the accountant. After asking him to sit down, she said to Bai Ruozhu: "Okay, I, Shi Qingning, am convinced. I believe you are doing your job and you are not cheating."

Bai Ruozhu smiled at her, thinking that although this young lady was a bit arrogant and domineering, she was also frank and straightforward and not annoying.

When everyone saw that Miss Shi had stopped talking, some people stood up to ask questions. Some were unconvinced and wanted to pass Bai Ruozhu's test, while others simply wanted to show off and ask difficult questions to gain face for themselves. You must know that in the past, those who could not participate in the competition could only watch with envy, without any chance to show their faces.

Bai Ruozhu answered one by one until a man stood up and asked a question about three-dimensional equations. He was probably inspired by the accountant of the Shi family, and then thought of a more difficult question.

"I'm going to buy the Four Treasures of the Study. Two brushes and an inkstone with four blades of paper cost thirty-eight taels of silver. The same inkstone and a brush with two blades of paper cost eighteen taels of silver. How much do these things cost?"

Bai Ruozhu didn't even make any gestures on the paper after hearing this. He suddenly laughed and said, "Brother, you made a mistake in this question."

The man's face changed, and he said unhappily: "What went wrong? You thought it was too difficult to answer, so you said I was wrong?"

Bai Ruozhu smiled and shook his head, "Did you know the price in your mind when you asked the question? Only when you know the price can you give it accurately. I think you just mentioned the price casually, right?"

The man was touched by Bai Ruozhu's words. His face turned slightly red, but he stretched his neck and said, "Then where did I go wrong? Tell me? Is there something else that you can't figure out that I did wrong?"

I found that the chapter updated at 8 o'clock in the morning had far fewer people reading it, so I changed it to 9 o'clock in the morning. Let's take a look first~
