Guan Shihao, Yang Qixian, and Zhang Jiucai, who were listening to Nangong Zhong, all had heavy faces, although everyone was confident, but the four magic problems of this champion building were only thinking that they could solve one or two questions, and they never dared to think about solving them all, but now, they ......

Pressure!

The heavy pressure was like a stone on the hearts of all the young people, especially Zhang Jiucai, Yang Qixian, and Nangong Zhong, who were still a little arithmetic.

"There is such a talented woman." Zhang Jiucai's eyes narrowed slightly, and then he walked to Chu Pingguang's side, "Brother Pingguang, borrow a pen and paper." ”

"Demnity." Chu Pingguang stepped aside and sharpened the ink at the same time.

Zhang Jiucai sat on the chair, didn't say much, and immediately took the pen and paper to think about solving the second arithmetic problem.

"I can only do my best." Yang Qi said in a low voice, and even walked to the seat vacated by the young man next to him and wrote it with a pen and paper.

Guan Shihao, Duan Changye, and Wang Zhonghe were not good at mathematics, and they couldn't help, but they just glanced apologetically at Qin Chao, Zhang Jiucai, and Yang Qixian and walked to the north of the list, where there were poetry exam questions.

"Brother Haifeng."

Nangong Zhong looked at the Qin Dynasty, "You can make a pair of three unique poems, calligraphy and paintings, obviously very good in learning, it stands to reason that you should be allowed to go to poetry and make a name for yourself, but now the situation is urgent, see if you can ...... it"

"Haha, I'm not good at poetry, I just know a little historical allusion, which is right." Qin Chao said with a smile.

"Brother Haifeng laughed." Nangong Zhonglian said, and the young people next to him also had strange expressions, saying that 'an official returns', this kind of downlink, poetry is not good?

"This column buried in the wall looks interesting, I'm here to play, maybe I can help a little." Qin Chao said, of course he knew that Nangong Zhong wanted him not to break into poetry and specialize in arithmetic.

"It's a good idea." Nangong Zhong's eyes lit up, and he said with a smile, "Brother Haifeng will definitely be able to help, and if you can't help, it's nothing!" "Nangong Zhong knows very well that this round wood buried wall problem is different from other arithmetic problems, no matter how difficult other questions are, it is also pure arithmetic, but this ...... It's completely confusing, and it may require more than just arithmetic, but something else.

"This Haifeng can match the pair of 'three uniques' in an instant, even if he has not learned arithmetic, he is also a rare smart and witty person, maybe his 'arithmetic' layman can find the key to solving this problem."

If it was purely logical arithmetic, Nangong Zhong would not look for the Qin Dynasty.

"Please prepare pen, ink, paper, inkstone and ruler for your brother." Qin Chaolian commanded.

"Ruler?"

Nangong was stunned, and the others were also stunned, and then-

"Clever!"

"Great idea!"

Qin Long and Qin Hu's eyes were as bright as stars, and when they shouted, many teenagers also reacted at this time, this arithmetic problem, in addition to the fact that it must be solved by the new temple students themselves, there is no provision on how to solve it, that is, you can use a pen to calculate on paper, you can also use an abacus to calculate, of course, this can also use a ruler.

And one with a ruler.

This second arithmetic problem, the so-called round wood buried in the wall, only need to draw a circle according to the requirements of the question, although this circle may be a little troublesome, but as long as you try a few times, you can draw it well, and then ...... Measure it with a ruler and the answer will be obvious.

In fact, this is also because everyone is limited by the idea of 'calculation', where is like the Qin Dynasty in the previous life, playing some brain teasers at every turn, engaging in some top-level innovation, and naturally broad-minded.

"Brother Haifeng, you wait, I'll borrow a ruler!" That Hu Qingxiu jumped high and ran towards the champion altar.

"Wait!"

"Wait a minute!"

Two voices rang out.

"What, Haifeng, Brother Jiucai?" Hu Qingxiu looked at Qin Chao and Zhang Jiucai.

"This arithmetic level is a test of numeracy ability." Zhang Jiucai said in a deep voice, "If we use a ruler to solve it, although it is not a violation, but after all, this will still fall into the inferior, which makes people see jokes." ”

"Yes, everyone is here to prove ability, not to solve problems purely for the sake of solving problems." Nangong Zhonglian said.

When he said this, many people also remembered the intention of this level, and some teenagers even looked at Gao Mingzhen, if they really solved it like this, even if the four questions were solved, the results were also pressed by Gao Mingzhen.

In fact, in addition to Zhang Jiucai's considerations, the Qin Dynasty thought more, and could get the answer with a ruler, but this answer was only an approximate answer, and if you were lucky, it would be exactly the same as the final answer, and if you were unlucky, it would be a few tenths of an inch worse.

"Everyone, I only want this ruler because I want to find a pattern after seeing this cylinder buried in the wall problem before, if I can find this rule, I may be able to help solve the problem." Qin Chao said.

"Regularity?" Everyone glared at the Qin Dynasty.

"Well, it's a right-angled triangle, the length of the two sides of the right angle." Qin Chao said.

"The law of the three sides of a right triangle?"

Zhang Jiucai and Nangong Zhong, who were having a headache for the second question, suddenly lit up: "That's right, the length of the three sides of this triangle may really be regular, find this rule, this problem may really be solved, well, this ruler must be found." ”

"Yes!"

"Qingxiu, hurry up and borrow a ruler!"

Many teenagers rushed out of the altar.

"You don't have to borrow it." At this moment, a beautiful voice like a silver bell sounded, "The law he said is true. ”

I saw Gao Mingzhen pinching a chess piece and looking at everyone with a smile: "That law is any right-angled triangle, the square of the length of the two right-angled sides is equal to the square of the hypotenuse, but this second problem, even if you know this law, it is not so easy to solve it, okay, you go to solve the problem, of course, you can't solve it, you can also use a ruler to measure." ”

"Thank you for telling me." Qin Chao smiled and arched his hand.

Gao Mingzhen snorted and ignored the Qin Dynasty.

"Don't worry, you will be able to solve it." Zhang Jiucai said lightly, then sat down, picked up the brush and scribbled on the paper, with this rule, it is no longer completely confusing to solve it.

"Brother Haifeng, you sit here!" A very pretty and delicate young man shouted timidly.

"Thank you, Brother Xinning." Qin Chaochong smiled and nodded at the young man next to him, and the young girl's face was slightly red: "Brother Haifeng, do you remember my name?" ”

"Of course, Yu Xinning, a very nice name, how can you not remember it?" Qin Chao said and sat down on the seat given up by the young man, "By the way, Brother Xinning, how long did it take for Gao Mingzhen to solve the problem?" ”

"For how long? That's what I've heard. Yu Xinning said happily, "Those people said that she answered the first question after just a few glances. ”

"Just a few glances?" The Qin Dynasty was surprised, the arithmetic problems from Tianlong Temple were not difficult for the Qin Dynasty, but this was because the Qin Dynasty was from the modern era, and the ancients could calculate this problem with a few glances, and the mathematical talent could be said to be very strong.

"Although she came up with the answer to the first question after a few glances, she used a cup of tea to answer the second question." Yu Xinning continued, "The third course didn't reach two teas, and the fourth one used three teas, and then she also came up with a problem to solve for the senior brothers, but the first question stumped the senior brothers. ”

"Stumped on one question?"

"Well, this question is in the hands of that girl." Yu Xinning said, referring to the girl standing next to Gao Mingzhen, who was also the first girl to guess the Qin Dynasty's 'Return of an Official' couplet, and the Qin Dynasty could see that the girl was holding an origami in her hand.

"What's the problem?" Suddenly, Qin Chao became interested in the so-called problem in the girl's hands.

"Okay, I won't bother you, Brother Haifeng, I'm very optimistic about you, you must help us solve those questions, especially the one that Gao Mingzhen came up with." Yu Xinning said with a smile.

"Hmm."

Qin Chao picked up the brush and scribbled on the paper at random.

"With the Pythagorean law, Zhang Jiucai should be able to solve this problem, right?" The Qin Dynasty wrote slowly, his eyes staring at the corona from time to time, and soon a cup of tea arrived. "Haven't solved it yet?" Qin Chao frowned, wrote the answer on the paper, and was about to get up.

"Haha, the answer is out!" Zhang Jiucai's voice sounded.

"How much?"

"How much?" Voices rang out.

"26 inches." Zhang Jiucai said excitedly, and at this time, Hu Qingxiu had already shouted at Zhuangyuanlou, "Senior brothers, someone has solved the second arithmetic problem, please come out." ”

"Solved?"

The voice in the champion building came out, and it was strange that it was a little surprised, and then a square-faced young man rushed out excitedly: "Which junior brother solved it, and what is the answer?" ”

"26 inches!" Zhang Jiucai said, arching his hand at the young man, "I don't know if this answer is correct." ”

"That's right!"

The young man was very happy and raised his eyebrows, "If you can solve this problem, then I will post the third question now." He strode out, and soon arrived at the south side of the Champion Altar.

"Come on!"

Hu Qingxiu handed over the wolf's hair, and after the young man caught it, he wrote it in the third column on the left:

"One hundred cakes and one hundred soldiers, the three chiefs are even more indisputable, the three soldiers are divided into one, and how many soldiers are there among the commanders and soldiers?" After finishing writing, he put down his pen and looked at Zhang Jiucai with a smile, "In Xia Peng Xianjian, I haven't asked my teacher brother Gao to have a big name." ”

"Peng Xianjian?"

Zhang Jiucai even bowed his hand, "Junior brother Zhang Jiucai has seen Senior Brother Peng." ”

"Zhang Jiucai, oh, I think about it, you are Zhang Jiucai who just 'Duanyang Chongyang', yes, the column buried in the wall can be calculated, it's amazing, but there is a requirement for this question." Peng Xianjian smiled and said, "This question must be solved with two ideas. ”

"Two?" Everyone was stunned.

That Peng Xianjian nodded at Zhang Jiucai, and then entered the champion building.
