When he heard the shouts of killing in the valley, Cao Miao had already asked five questions.

These five questions are not difficult, and they can even be said to be scored questions, as long as you have learned nine chapters of arithmetic, and your brain is not bad, you can answer them. Even if you need to think, it won't take long.

Xiahou Yan became more and more courageous the more he fought, and he answered three questions in one go. Three yellow gold cakes were placed on the table, illuminating her eyes and stimulating the nerves of Xiahou Hui and Sima Guo. For the honor of the family and his own future, Sima Guo had to abandon his distracting thoughts, calm down, grab a question, and get a gold cake.

Xiahou Hui was anxious. Cao Miao's questions, she knows, but because she has to take care of Sima Guo, she has never dared to answer. By the time she realized that the rules of this assessment were different from those during the day, she had already missed a few opportunities, and watched Xiahou Yan pick up the bargain.

Seeing that Sima Guo answered a question and won a gold cake, she finally relieved herself and followed the answer, barely saving face.

At this time, there was a shout of killing outside, the battle in the valley had begun, Xiahou Hui and Sima Guo were a little absent-minded, only Xiahou Yan was still unfinished, urging Cao Miao to continue to solve the problem.

Cao Miao said: "That's it, I'll give another question at the end, you answer it slowly, I'll go upstairs and take a look." ”

"What kind of question, do you have to answer it slowly?" Xiahou Yan shouted. "Take out all the remaining five questions and read them slowly."

Cao Miao smiled bitterly and begged: "Little sister, do you think I don't want to?" Each of you answers one question, but I have to answer three questions. My head is about to crack, and it takes a lot of effort to come up with another question, where did the five questions come from? ”

Seeing Cao Miao's distorted expression and a painful look, Xiahou Hui was a little relieved, but he was afraid that Xiahou Yan would force him too hard, causing Cao Miao to become ill, so he took the initiative to stop Xiahou Yan. "Just follow the townsman, if you ask another question, let him go upstairs to blow the wind and rest for a while."

"Okay." Xiahou Yan didn't dare to confront Xiahou Hui head-on, so he could only nod obediently. Anyway, she has already won three lanes, which is enough to prove herself.

Cao Miao cleared her throat. "There are 100 gold, put it as money, one cent of monthly interest, plus profit, ask, three years, how much profit?" With that, he grinned and showed a tired smile. "You guys take your time, I'll go up first and see, who has solved it, let people call me." Get up and go.

Xiahou Hui and the three looked at each other. This question is not difficult, let go of the money for profit, even if you haven't let go of the money, at least you have heard of it. But it's complicated, the monthly profit, or the profit plus the profit, count it for three years, that is, at least thirty-five times, and put a lot of calculations, which makes people's scalp tingle when they think about it.

Xiahou Hui hurriedly stopped Cao Miao. "This question is meaningless, counting three years is no different from counting three months, it's just more cumbersome, you are deliberately playing tricks on us. Switch one. ”

"Really?" Cao Miao scratched her head.

"Yes." Xiahou Yan and Sima Guo said in unison.

Cao Miao blinked and rubbed her hands. "Okay, I'll change the hard one. This is the hardest question I know, comparable to five questions. Whoever of you is the first to answer will be rewarded with hardware and become the wisest one. If you can't answer, don't blame me. I will take the first five questions as the final result and declare the little sister the winner. ”

"Yes, yes." Xiahou Yan clapped his little hands and applauded, and when he saw Xiahou Hui's eyes that he was about to eat people, his voice lowered again. "Good...... bar. ”

Xiahou Hui and Sima Guo exchanged glances and cheered each other on. This is an opportunity to fight back, and we must seize it firmly.

Cao Miao coughed: "There are ropes and ropes, and the ground is enclosed with ropes, and there is no limit to the width and narrowness of the square circle, and the maximum amount of land can be enclosed?" He looked at Xiahou Hui and looked timid. This question ...... Okay, right? ”

Xiahou Hui nodded and said, "This question is somewhat interesting, but it shouldn't take long." You go and rest for a while, and we'll go and ask you for it. ”

"Okay." Cao Miao was relieved and went to the back hall with joy.

Looking at Cao Miao's childish demeanor, Xiahou Hui and the three of them laughed dumbly, spread out the paper and pen, calculated the chips, and calculated. They all thought that this question was not difficult, it was similar to the Fang Tian technique in the nine chapters, but with a slight change. However, when I calculate it, I find that this change has a great impact.

Cao Miao asked for not a specific area, but a maximum value. In other words, they first have to calculate different shapes before they can pick out a maximum value from them.

How many kinds of rope are there in different shapes?

Countless kinds. It can be square, it can be round. There are different squares of squares, and a circle can be a perfect circle or an oblate circle. There can be other shapes, all in all, this is even more computationally intensive than the previous question.

No wonder Cao Miao said that this question is the most difficult question he knows, and one question is worth five.

As smart as Xiahou Hui, he was helpless for a while. Sima Guo and Xiahou Yan were no exception, and they were all scratching their heads.

But their mood is very different. Xiahou Yan has three golds in hand, and if everyone can't answer, she is still the winner. Even if one of them answered, she wasn't the worst. So she was still relaxed, and while thinking, she secretly looked at Xiahou Hui and Sima Guo.

Xiahou Hui and Sima Guoke were not so easy. On the one hand, they are extremely eager to solve this problem and prove that they are not stupid. On the other hand, they were concerned about the battle outside the village, and they didn't know if Sima Yi and the others could win or if they would be injured.

Although Sima Yi has rich experience in actual combat, and the knights around him are also real elites, but the sword is eyeless, and the arrows are ruthless, no one dares to say that it is foolproof. If something happens, it's the difference between life and death.

Xiahou Hui thought of Sima Shi, and his heart was even more uneasy. Sima Yi is the head of the family, and he must ensure his safety, and there is a high probability that he will be in command. Sima Zhao has not yet weakened the crown and has no combat experience, so he will definitely not rush to the front. Sima Shi is the eldest son, and he will rush to the front as a matter of course.

But he had been injured not long ago, and although he had recovered well, he had not recovered yet.

Will he be able to fight?

Xiahou Hui really wanted to ask Cao Miao to send someone to support. She knew that Cao Miao had several masters around her, such as that Ah Hu. But she couldn't open it. She knew that Cao Miao didn't like Sima Yi's father and son, and she had a very bad impression of Sima Shi. Let him go to reinforcements, it is obviously unlikely.

If he really had this heart, he would not have driven Sima Yi and his son to camp in the river valley.

Xiahou Hui's heart suddenly moved. Could this be Cao Miao's intention? Under the pretext of repairing the villa, he drove Sima Yi and his son to camp in the river valley, and then arranged for people to attack them, causing them to die.

Xiahou Hui thought of the joke that Cao Miao said about supporting his family, and his whole body was cold.

Obviously, it was not a joke, but Cao Miao's long-planned plan.

The more Xiahou Hui thought about it, the more scared he became, and he couldn't care about any questions anymore. She excused herself to go to the toilet, got up and went down to the hall, and found Xiahou Xu. Xiahou Xu was getting tired of Yun Niang in the kitchen, and was broken by Xiahou Hui, and he was somewhat flustered.

"Yuanrong, are you hungry? I'll ask Yun Niang to get you something to eat. ”

Seeing Xiahou Xu flustered, Xiahou Hui became even more suspicious and opened the door. "Bo Yuan, the people who are attacking Taiwei's father and son outside were arranged by Yunliang, right?"

Xiahou Xu was stunned for a moment, and then said: "What nonsense are you talking about, this matter has nothing to do with Yunliang, it is Desi himself......" He immediately realized that something was wrong, and hurriedly covered his mouth with his hand, and swallowed the rest of the words back, his eyes flustered.

"Desi?" Xiahou Hui's face turned pale, glared at Xiahou Xu fiercely, turned around and ran towards the back hall.
