The woman who spoke was Shi Qingning, the youngest daughter of the commander of the Xijiang camp, Shi Qingning, the scale of the Xijiang camp was not as good as the northwest camp, but it was the main force in the southwest region to resist the enemy, and it was also because of this relationship that Shi Qingning was a little unhappy with Bai Ruozhu.

Shi Qingning is the youngest child of Quartz, so she is particularly loved, she is also a little arrogant, and she is also a little bully in Jiangnan, even Xu Panrui and they dare not provoke her easily.

She really saw that Bai Ruozhu was too brilliant, so she wanted to find trouble with Bai Ruozhu, it happened that she recently read some information in Hetuluo's book and found such a question, and even discussed it with her brothers and sisters, but everyone didn't figure it out. As soon as she thought of it, she was a little proud and wanted to trouble Bai Ruozhu, but after she finished speaking, she saw a smile on the corner of Bai Ruozhu's mouth.

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

The audience was in an uproar, and everyone pondered after listening to Shi Qingning's question, and felt that it was really difficult, not only to add three horizontal rows and three vertical columns together, but also to have the same two diagonal pairs, that is, the eight groups of numbers must add up to the same result, this, is this possible?

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

"What, how can it be so fast?" Shi Qingning asked in disbelief, if it was before, she might have laughed at Bai Ruozhu for bragging, it can be seen that Bai Ruozhu has done so many questions correctly, and she didn't dare to underestimate Bai Ruozhu in her heart, otherwise she wouldn't have come up with the questions in the Tuluo book.

Bai Ruozhu smiled, turned his head to the little guy on the side and said, "Please help me move the table and banknotes here, and I'll write them out for everyone to see." ”

The little guy who helped in the competition field hurriedly moved the table to Bai Ruozhu, and helped her spread out the paper and pressed it with a paperweight.

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

Bai Ruozhu drew a big nine-square grid on the paper, and then wrote down nine numbers in Chinese characters, but she almost wrote Arabic numerals as soon as she got used to it, which made people think she was drawing a ghost.

"Okay, let's see if it adds up to fifteen. Bai Ruozhu said, picked up the paper and hung it on the fixed shelf next to the table.

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

Bai Ruozhu saw that Shi Qingning was very serious in calculating, and subconsciously wrenched his fingers, almost didn't laugh out loud, and said in his heart, this girl has to come to test her if she wants to wrench her fingers and arithmetic?

But does she count as bullying the ancients?

Someone in the judges' table has already written down this answer, and the judges have also exclaimed, saying that this question is good and the answer is better.

"That's really right, how can you be so fast?" Shi Qingning's tone was much better at the moment, not as rushed as before, just looking at Bai Ruozhu curiously.

Bai Ruozhu smiled at her and said, "I've done this question before, so it's a trick." ”

Shi Qingning was stunned, but quickly laughed and said, "It's also your ability to make it, and no one can know the title on this Hetuluo 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 Olympiad of elementary school, and the same nine-square grid could also fill in another set of numbers, and it was still according to this rule, but she didn't know that this question was very rare in Danliang Kingdom, or it was in Hetuluo's book.

She simply chose not to speak, still with a faint smile on her face, which seemed a little unfathomable.

"But I'm not convinced by this alone, we're not good at arithmetic, so ask my bookkeeper to give you another question." Shi Qingning said.

"Good. Bai Ruozhu saw that there was already a middle-aged man sitting next to Shi Qingning, and she knew that she had said before that she would let the audience test her, so Miss Wei called someone in advance.

The bookkeeper of the Shi family stood up, respectfully saluted Bai Ruozhu, and said, "Miss Bai, I have a question." ”

Bai Ruozhu saw that he was very respectful, and also returned the salute to him, saying, "Please." ”

"The day before yesterday, the house bought four carts of melons and fruits and two carts of vegetables, a total of 26 taels of silver, yesterday, the house bought the same melons and fruits and three carts of vegetables, a total of 14 taels of silver, may I ask how much a cart of melons and fruits cost?

Shi Qingning was very happy to hear it, and he also gave a thumbs up to Mr. Reconciliation Room, which means that this question is good and difficult.

Bai Ruozhu mentioned some interest, it can be regarded as a problem of a binary equation, she took a pen and quickly swiped it on the paper a few times, and quickly calculated the answer.

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

The bookkeeper's face changed, "I didn't expect Miss Bai to figure out the answer so quickly, and I can't test Miss Bai if I don't know it." ”

Everyone calculated according to Bai Ruozhu's answer, and it was indeed right, but if there was no answer, it would not be easy to calculate it so quickly.

Shi Qingning didn't blame Mr. Bookkeeper, and after asking him to sit down, he said to Bai Ruozhu: "Okay, I, Shi Qingning, believe that you are your own ability and have no cheating." ”

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

Seeing that Miss Shi stopped talking, some people got up to ask questions, some were unconvinced and wanted to test Bai Ruozhu, and some people simply wanted to show their faces and ask a difficult question to give themselves a long face. You must know that in the past, those of them who couldn't participate in the competition could only look at it with envy, and there was no chance to show their faces at all.

Bai Ruozhu answered them one by one, until a man stood up and came up with a three-way equation problem, he was probably inspired by Mr. Shi's bookkeeper, and then thought of a more difficult question.

"I'm going to buy the four treasures of the study, two brushes and an inkstone cost thirty-eight taels of silver, and the same inkstone and a brush and two knives of paper cost eighteen taels of silver, ask how much money each of these things is?"

Bai Ruozhu didn't make a comparison on the paper when he heard this, so he suddenly laughed and said, "Brother Tai, you made a mistake in this question." ”

The man's face changed, and he said a little unhappily: "What went wrong? It's because you think it's too difficult to answer, so you say I'm wrong, right?"

Bai Ruozhu shook his head with a smile, "Did you have a count of the price in your heart when you came up with the question?

The man was told by Bai Ruozhu, his face was slightly red, but he stretched his neck and said, "Then where am I wrong, do you say?
