The eyes of all the judges and contestants fell on Bai Ruozhu, and she could only smile and stood up from her chair.

"I told you during the last calligraphy competition, I have a very good memory." She suddenly said this, and those who heard it couldn't help but think of the scene during the calligraphy competition, especially the man who asked her, his face was even darker. It didn't look good, and I couldn't help but shudder.

Bai Ruozhu didn't seem to see any of this, and said to himself: "I met an old man before and said that this was a sign of flexibility in the brain, so I calculated many spells directly in my head, which is more difficult. It only took a few strokes on the paper. So this is my own problem, please don’t blame Sai Fang by mistake.”

Everyone listening looked in disbelief. They could just calculate it in their heads without using an abacus? Isn't this awesome?

In this time and space, there are no arithmetic methods such as the multiplication table. In addition, the Danliang people do not pay attention to arithmetic. Even the abacus method is much clumsy, so these two-digit multiplication and division are not simple for them.

But Bai Ruozhu said this as if she was wrong for using her head too well. Many people who heard this wanted to rush up and beat her up, and then ask God, why did such good luck not happen to them?

"If you don't believe what I say, after the competition is over, a few people in the audience can come out and give me questions, and I will answer them on the spot. Then everyone will know whether it was me who calculated faster or I got the answer in advance. . As for now, everyone should not affect the normal progress of the game." Bai Ruozhu said again.

The judges nodded one after another, thinking that Bai Ruozhu's idea was a good one. The competition continued as usual. Afterwards, the audience gave her a question. If she could not prove her ability, the competition would cancel her ranking.

"What Bai Ruozhu said makes sense. The competition will continue. Anyone who has any questions will ask questions later." The judge said loudly.

Although everyone didn't completely believe Bai Ruozhu's words, they had no choice but to give face to the competition, so they didn't say anything more. They were only thinking about how to give Bai Ruozhu questions later. Many people even lost interest in the comparison test. I hope It's over soon.

There were many old-school Jiangnan official family members in the audience who did not like Bai Ruozhu. Most of these people were close to the Xu family on weekdays. There were also some young ladies who were friends with Xu Panrui and the others. The calligraphy competition made them She felt that Bai Ruozhu not only slapped the Xu family and the Sun family, but also severely disgraced them Jiangnan nobles.

If you want to ask why they don't hate Jiang Yichun who rushed into the field with 200 elite soldiers? The reason is simple. They were really frightened and did not dare to hate Jiang Yichun, who was very cruel and domineering in his attacks. They could only pick the weaklings.

After that, the competition continued. Each question was more difficult than the last, but no matter how difficult it was, it was only three-digit addition, subtraction, multiplication and division. Even the equations Bai Ruozhu learned in her previous life had never been used. She only crossed them twice on the paper. , and answered all the questions easily.

The faces of the other contestants became more and more ugly. They said they were trying to answer the question, but they couldn't answer it together. Didn't they lose points?

There was also some small discussion at the judges' table. If this continues, the second place will be incomparable. No one expected that such a situation would happen today. That Bai Ruozhu is too strong.

Bai Ruozhu curled her lips secretly. She didn't want to be like this at first. Who would have thought that she would be questioned just after answering a question. She had to say that she could do mental arithmetic. Then she couldn't hide her clumsiness and let others question it. Who would let these people question it? What about her? She had no choice but to calculate the answer honestly.

Finally, the judges seat called the referee and whispered a few words. Soon the referee came down and said loudly: "Change the rules of the competition. After the following questions are presented, the contestants should not speak out the answers after calculating them, but write them on paper and hand them in." , the first five to write the correct answer will get one point.”

In this way, there is no obvious advantage in calculating quickly, but Bai Ruozhu has scored so many points in the past, and it doesn't matter at all the remaining questions.

As the competition continued, Bai Ruozhu was still the first to hand in the answer. Others finally had a chance to figure out the answer, but many people looked sad, obviously stimulated by Bai Ruozhu.

At the end of the competition, Bai Ruozhu had the highest score without any doubt, and the second place went to the yellow-faced man who asked the question. No wonder he was unconvinced. It turned out that he was the best in magic, and he came here just for the first place. .

The third place was from Chang'an Academy, the fourth place was from Tianfu Academy, and Bai Ruozhu didn't expect that the fifth place was Jin Junfeng from the delegation today. He had participated in the riding and shooting competition before. Bai Ruozhu didn't expect it at all. His magic skills are so powerful.

The audience didn't care about the ranking of the competition at all and were already eager to try. A famous young man lost his patience and shouted loudly: "Can we give Bai Ruozhu a question?"

The judges nodded one after another, and they all wanted to rely on the following questions to prove the innocence of the contestants. The referee looked at Bai Ruozhu, asking her if she could start?

Bai Ruozhu took a few steps forward, brought herself closer to the audience, and smiled at everyone: "It's time to start. If you don't believe it, you can come up with questions, but I will also say the ugly things in front of you. Don't ask questions yourself." If I don’t know the answer, how can I prove whether my answer is correct?”

This kind of simple addition, subtraction, multiplication and division of two-digit and three-digit numbers is very simple for her, but no one can ask random questions, such as how many stars are there in the sky? Should she answer like Afanti? As much as your hair?

There were a few people who were eager to give it a try, but they couldn't help but languish when they heard this.

"We are not masters of magic. How can we know all the answers? Bai Ruozhu, aren't you scared?" asked a woman in luxurious clothes.

Bai Ruozhu smiled at her, "Do I need to be afraid? If you don't accept it, I will fight. I am just speaking objectively. If no one knows the answer, how can I confirm whether my calculation is correct?"

"Then let the people behind you calculate the answer together, and the judges can also calculate the answer. Are you still not sure whether you are right or not?" the woman said again.

Bai Ruozhu said calmly: "I don't dare bother the judges and other contestants. This matter cannot be asked of me."

The woman looked towards the judges' seat. The judges looked at each other and could only nod their heads, saying that they would work with the people present to judge whether Bai Ruozhu's answer was correct or not.

The woman stood up, and the other people who were going to give the questions sat down again. Bai Ruozhu observed secretly, fearing that this woman's identity was unusual.

"I once saw a question about a nine-square grid and found it very interesting. It's just that my daughter is stupid and has never been able to figure out the answer. I don't know if Bai Ruozhu has this ability." The woman said.

Bai Ruozhu nodded, "Please speak."

"How can one to nine be arranged in the nine-square grid so that there are three horizontal rows and three vertical columns, and the two diagonal ends add up to the same number?"
