Vol 2 Chapter 10:

"The title I gave is ..." The third princess said half-way, but stopped her lips, smiled slightly, and her eyes glowed with water, revealing a touching style instantly. It is worthy of being a world-famous beauty. When she smiled, even Fengming flashed, and she said: My little sister-in-law is so beautiful, but my husband was killed by Rong Wang and became a widow. If I destroy her second Chun, that's too pathetic. Thinking of this, could not help turning his eyes to Li Ruoyan.
It ’s okay not to turn your head. When you turn your head, you immediately face a sharp look. Feng Ming has never seen such a sharp look in her life, which is reminiscent of the word electricity.
Rong Wang's gaze was also like electricity, but it was embarrassing. If he accidentally touched the power switch. If Li Li's gaze was like a flash of lightning splitting from the sky, the cold possessiveness had been carved into Fengming's heart, scaring him out of cold sweat.
I never knew that a man could tremble him so much with his eyes.
If Liming turned to see Fengming, he immediately converged the light in his eyes, nodded to Fengming, Fengming's hair was full, and he moved back secretly. "Prince?" The brain was appeasing the heart that was frightened by the sudden lightning. Suddenly someone yanked Fengming's sleeve beside him, he turned back suddenly, it turned out to be a wild goose.
"Prince?"
"Ok?"
Fen Yan laughed: "Prince Anhe, the title of the three princesses is out."
"Oh? Really?" Fengming quickly raised her sleeves and wiped her forehead. She could avoid Ruo Yan's sight and turned to the third princess. When the three princesses saw Fengming's face pale, she frowned, "What's the matter about the prince?" He groaned for a moment, and then said, "If the question I asked was unsolvable, if the prince wouldn't, it would be normal.
"It's okay, it's just ... a little cold." Feng Ming perfunctoryly took a closer look. It turned out that the three princesses had already drawn a circle with a bamboo pole in the sand pool. It seems that she has already studied the circle a lot, and she just draws it, which is almost the same as drawing with a compass.
Everyone's eyes are focused on that circle, don't think about it, this is the problem.
Fengming frowned: "round?" Pondered in her heart: do you want me to find the circumference of the circle? Or the area of ​​a circle? Secretly regretted that he had n’t heard the question clearly, so he had to bite his head and arched his hands: "Wang Wang forgive me, the previous title Anhe didn't hear clearly, can you repeat it?"
The three princesses looked at Feng Ming in surprise and asked, "Since the Prince has studied the calculus, how can he be unaware of the problems in this world?" Oops, it seems that this circle is a well-known topic in contemporary calculus. Once you are famous, you should know what is going on. Thanks to the kindness of the geese, he whispered in the back: "Prince, the third princess asked the prince to calculate, how much sand can be filled with a large ball."
In the end, modern arithmetic is developed. Feng Ming put the subject in his head for a few turns and immediately realized that it was a circular volume. Haha, this is not easy? Fengming's tight nerves all loosened, and she couldn't help showing a smile, and replied casually: "This question is simple. The volume of the ball can be calculated using a formula. You only need to know the radius. The formula is four-thirds. дR cubic. "
He answered easily, and everyone in the room couldn't help but be surprised. The three princesses froze and asked: "The Prince said that this palace does not quite understand, what is a shoot, what is it? What is a four-thirds? What is a cube?"
"That's simple, please see the princess." Fengming grabbed the bamboo pole, wrote the formula on the edge of the sand pool, and drew the radius in the circle, and answered patiently: "The center of the circle to the edge, we call it R, The beat is a number equal to about 3.14159, the cube is the cubic, three quarters are multiplied by four and divided by three ... "Thanks to the math class being punished by the teacher for more than twenty times on the day, he compared the three princesses to the formula If you don't understand, one by one detailed answers, it looks like a master calculus.
Fen Yan and others met for the first time, all scrambling to probe to see his sketch in the sand pool. Dongfangtian even narrowed his eyes and heard the white beard shake. The scientist really paid attention to practice in any era. When Feng Ming explained, he had called the waiters around him to take the measuring equipment and test whether the formula of Feng Ming was correct. Their measurement method is very simple. Inject fine sand into the ball, and then pour out the fine sand one by one. Use a square wooden box to measure the amount of fine sand in the ball.
Several consecutive spheres of different sizes were tested in succession, and the results really did not differ much from Feng Ming's formula. So far, the looks of the three princesses and Dongfangtian can only be described by shock. Both of them are masters who have been devoted to calculations for many years. When they see the world ’s problems solved, they are as moved as if they suddenly saw heaven on earth.
Dongfangtian almost couldn't even speak a good word, choking his throat and said, "Three princesses, this ... this is really good." The third princess looked at the formula written by Fengming for a moment, and her face suddenly became flushed, just like Seeing the lover of great love, suddenly looked up to Fen Yan said: "Hurry up, get ink and write down these." Fen Yan was busy to go.
Then she turned to look at Feng Ming and said excitedly, "Prince Prince, the palace is neglecting. This world ’s problems, Fanzhi Hexing, can actually see the eternal problems solved with his own eyes. Worship. "Immediately kneeling straight, Volde worshiped.
"Wang Wang, please, Anhe dare not be a lord!" Feng Ming could not have expected that she would be so excited, and quickly changed color to help the three princesses. Before the three princesses were lifted up, Dongfang Tian actually came to join in a lively, tears filled with tears: "Dongfang Tianfang was rude to the prince, so ashamed, please forgive His Royal Highness." He also lay down with white hair.
Fengming was flushed with shyness, and after finishing this one, she said, "Everyone please rise up, please rise up." Ruo Yan stood by and looked silent. After all, it stopped a mess, and sat around the bunker floor again. The three princesses were excited, and asked, "This formula is truly amazing and amazing. But I don't know how it was calculated by the tool called the abacus. Can the prince see the report?" "Yes, If such a clever tool can be glimpsed, the old man will die without complaint. "
Fengming then remembered that she was boasting that the abacus in the sky was still in the house, and she was holding it. Although he memorized the formula by rote, how did the spheric volume formula come about? Forty percent of the formula had been forgotten, not to mention that the abacus and volume formula couldn't be beaten together. How can we answer this question? Dongfangtian waited excitedly for the answer. When he saw Fengming hesitated, he thought for a moment, then realized suddenly: "Oh, this is the technique of West Ray calculus, and Prince Edward is inconvenient to leak."
The disappointment of the three princesses immediately overflowed with words. At this time, offending the three princesses was not a good thing. Things are going well now, we must use them to complete the task to deceive the three princesses back to Xilei. If that was so terrible, the third princess would not marry him. Thinking about this, Fengming's brain quickly turned up. He lowered his head slightly, and suddenly showed a charming smile. Huo Ran stood up, slowly glanced at the people in the room, and when he met the sight of Ruoyan, his heart was inevitably scared. But on the surface it didn't matter.
Finally, his eyes fell on the faces of the three princesses, and he arched his hand handsomely, respectfully said: "It is not that Anhe cherishes the technique of Xilei calculus and refuses to elaborate on Wang Xi, but this formula is calculated by Rong Wang. How to calculate, Anhe also It ’s not clear. But it does n’t matter. When Wang Xi arrives in Xilei, Wang Rong will naturally ask Wang Xi to ask for calculations. Oh, Master Dongfangtian is also welcome to Xilei. By then, the masters can meet the masters, and the arithmetic can naturally advance thousands of miles. For the benefit of the world. "He liked the old man with a real temperament and sold him a personal relationship.
As for the sphere volume formula, Rong Wang figured it out, let Rong Wang clean up the mess in the future.
Upon hearing the three princesses, her eyes lit up. At this time, compared to Rong Wang who can solve the problems in the world, Ruo Yan's invitation has lost its charm. Gu Ji Ruo Yan was present, and she only slightly bowed her head: "Thank Prince, Xi Lei Rong, Fan Zhi has been known for a long time. Seeing the last one, I made my wish. "With that said, the intention to go to West Ray was fully revealed.
If you know that you can't compete with the calculations, smile at the three princesses with a graceful smile and stop talking. The secret look at Fengming was as powerful as an arrow from the wind. Fengming was also observing Ruoyan's movement in the dark, and he was stung by him, like a frog stared at by a poisonous snake. He was so cold that he almost couldn't move.
He listened to the three princesses, thinking that the mission was at least halfway, but it was better to avoid the king quickly, and arched to the three princesses: "Anytime I disturbed Wang Xi, Anhe still left."
As soon as he heard that he was leaving, the three princesses and Dongfangtian both showed reluctant expressions.
The third princess said: "The prince is leaving so fast, how about staying a little longer?"
"Yes, the old man has many calculus problems and is trying to ask the Prince."
Feng Ming was stabbed by the eyes of Ruo Yan from time to time, where she would stay, and waved: "It is indeed important that Rong Anhe will visit again next time." The three princesses helplessly, got up and sent Feng Ming out. General Hitomi also came out from the side hall where he drank tea. Everyone met outside the third princess's house and saw the third princess's attentive attitude towards Feng Ming secretly.
On the carriage, not only Lieer, but also Xia Guan also squeezed into Fengming's carriage, but General Tong Tong rode on the horse and was tall and unable to squeeze in. As soon as Xia Guan got on the bus, he said, "Congratulations to the prince, the prince must show his power and persuade the three princesses to return to Xilei." Fengming smiled and asked: "How does Mr. Xia Guan know?"
Lieer spoke quickly and interjected: "It depends on the attitude of the three princesses to the prince, who can't see it?" "Moreover, Li Ruoyan's face is not very good-looking, I'm afraid it is a marriage proposal. The prince is really brave and knowledgeable. I am also worried that the prince is young. If I am alone, I am afraid that I can't cope with it. It seems that I am worried. "
Xia Guan smiled and nodded in appreciation to Feng Ming. Fengming thought of Ruo Yan, and that terrible gaze appeared in his head. He shivered and smiled: "Don't mention Ruo Yan, that person is terrible. As soon as I got close to him, I couldn't help shaking."
"But he is still not as good as his prince, so he can't win the hearts of the three princesses. By the way, I don't know what great strategy the prince has used to deal with Ruo Yan?" The carriage was drawn with fingertips, and the matter was explained in detail. His eloquence has always been good. At this moment, there is no burden on his mind, and he is relaxed and relaxed. He also described the ups and downs of the ups and downs. Xia Guan and Lieer were intoxicated, and clapped from time to time.
At the end, Xia Guan sighed: "Xia Guansu knows Wang Rong's ancient and modern times, and knows astronomy and geography, but he didn't expect that even the calculations reached such a realm." Feng Ming remembered that he had blown a big cowhide for Rong Wang, hehe laughed Two beeps, silent. The team arrived at the hotel where they were staying, entered the house, and a few people in the autumn basket waited for a day. When they saw Fengming ran and greeted them with a smile. The three maids embraced Fengming to change clothes, Qiu basket said: "Congratulations to the prince, the three princesses will be brought back to Xilei in a few days, Wang Rong must be very happy to know."
"How do you know?" Qiu Xing nodded thickly and nodded with a smile: "Of course, our prince is very romantic, the world is unparalleled, and the three princesses will be willing to go back with us."
"Please, Qiu Xing, we said these things yesterday. You need something fresh."
"Hmm, His Royal Highness is romantic every day, and we can say it every day. Qiu Lan, you are just looking at Mr. Xia Guan and General Tong's faces, guessing the good news, what's the matter?"
Fengming thought it was funny and raised his hand and said, "Okay, it's going well today, we can return to Xilei soon, everyone is happy." He announced that the three girls were even more embarrassed. Excitedly asked whether the princess's looks were as beautiful as rumors. Laughter and laughter, came out of the hall.
