Chapter 12

As members of the Cheng family, most of them knew Cheng Jinzhou's status as a sick child, and while commenting on his self-recommendation, most of them were not optimistic.

However, more people are worried that the old lady has lost face.

Prefect Cheng Yun'an also had the same worries. He looked gently in the direction of Cheng Jinzhou, coughed and said, "Mother, Cheng Bingxun is older than Jinzhou, so let him plucking his hair first."

Although Cheng Jinhao studied with the imperial examination as his goal, so did Cheng Jinzhou. Comparing the two shorts, there is always a shorter...

Cheng Yun'an couldn't lose the dignity of the old lady because of her anger.

Cheng Jinzhou looked up at the cheap daddy, feeling a little angry, but it soon disappeared and he comforted himself: it was just for money anyway, and there was not much difference between the first and the second.

He was about to give up, and Mr. "Charity" also showed a proud smile.Unexpectedly, the old lady was a strong-tempered person and did not let the situation go downhill. She stood up and said: "Cheng Jinhao is indeed older, but the rules of our ancestors are not calculated in this way. Since Bingxun brought it up, the old lady will check it out here. .”

The words were polite and proper, and there was a hint that this direct grandson is not the other's direct grandson. The people of the Longzi branch were so arrogant that they couldn't even raise their heads. Cheng Bingxun made the move first, but they didn't stop them. They didn't even say a word of retort. nothing.

Pulling green is a trivial matter, the old lady didn't care much about it, and didn't prepare any topics. At this time, she said with a straight face: "If you want to talk about mathematics and physics, my old lady is not proficient. There are a few astrologers here today, let They ask a question, I will ask another question, if any of you can answer it, go in first."

In the era when astrologists were very popular, the art of mathematics and science was a compulsory course for the nobles, and the old lady's so-called "not proficient" was just a modest word.

Cheng Jinhao took a few steps forward and stood next to Cheng Jinzhou, but his father Cheng Bingxun looked even more nervous than his son.

Cheng Jinzhou turned his head indifferently, and immediately found a group of men in black robes appeared on the west side, and he was suddenly stunned.Different from the three star warlocks who visited as guests, the level of the current black robes is much lower. They are star warlocks funded by the Cheng family. I think, let alone possible stars, so I can only find some wealthy families, on the one hand to support their appearance, on the other hand, to obtain some financial assistance-no matter what kind of research it is, it is very expensive.

Not enough than the top, more than the bottom, at least compared to those guys who have no potential to become real star warlocks in their lifetime, the black robes on the west side are still very lucky, at least their mathematics level is much higher.

One of them walked up to the front first, and said with a smile: "Then I have a question, let's check the school for two."

This astral magician was about thirty years old and had a beautiful beard. Thanks to the family's respect for the astral magician, he was able to stroke his beard freely and said with a smile as if watching a play: "There are 35 pheasants and rabbits in the same cage today. There are 94 legs underneath, how many are each of the pheasant and rabbit?”

Cheng Jinzhou almost laughed out loud.

The problem of chicken and rabbit in the same cage is a typical Chinese problem. Starting from the Nine Chapters of Arithmetic and continuing to the civil service examination in later generations, it has always been a classic problem.Its essence is actually not complicated. A chicken has two legs and a rabbit has four legs. Knowing the number of heads and legs, finding the number of each is nothing more than exchanging two legs and four legs. Smarter primary school students can also complete it.If the use of equations is allowed, and it is simplified into a linear equation of two variables, stupid college students can calculate it as manual work - but when it comes to speed, I cannot praise it.

In the civil service examination in China in the 21st century, the corpses of those who know how to do the questions but have no time to do the questions are everywhere.

However, in this era when nine-chapter arithmetic is rare, the problem of a chicken and a rabbit in the same cage still makes Cheng Jinhao next to him think hard.One-dimensional and two-dimensional equations were fairly common in the Great Xia Dynasty, but they were not homework that teenagers needed to study.It is also quite difficult to come into contact with similar problems for the first time.

Cheng Jinzhou glanced at the nervous cousin, decided not to give the father and son any face, and replied straightforwardly: "Rabbit 12, pheasant 23."

He didn't even use a scrap of paper.

His quick answers and precise calculations made the man in black robe on the stage look at Cheng Jinzhou very highly, and said with a smile: "Yes, the correct answer."

Cheng's mother became happy first.There was a faint smile on Cheng Jinzhou's face, but there was also a slight change.

Before going to college, his mathematics and physics were quite good, and occasionally he fantasized that he would become a new generation of Einstein, Bohr, Rutherford...But the facts proved that as the elitism of his classmates deepened, his personal vulgarity became more and more prominent. After Cheng Jinzhou got the master's title, he disappeared among all living beings, and he couldn't see any good innate genes.

Suddenly, finding himself in a possible elite position again, Cheng Jinzhou didn't know what to show.

"Happy to do good deeds" Cheng Bingxun's face was frighteningly cold, and he looked at the middle palely. Before his son could calculate the result, he shouted loudly: "The topic has been prepared a long time ago. Who doesn't know that Cheng Jinzhou is famous for his medicine jars. I haven't been there a few times..."

The man in black robe suddenly flicked his sleeves and glanced at Cheng Bingxun angrily. As a star warlock, he cherished feathers very much.

Mr. Le Shanhao didn't care too much, and said directly: "Auntie, you have always been a fair character, this question can't be counted, and he can answer it..."

A series of words showed his contempt for Cheng Jinzhou.If there is no time travel, the future of this sick man will indeed be very bleak.

The old lady raised the tea bowl next to her with all her strength, slammed it on the table, and said in a bad tone: "It's just a child's play, but you are so shameless?"

"I just want fairness and an explanation." Cheng Bingxun put on a rogue face.

A group of people covered their faces with their sleeves and looked like they couldn't bear to read. Cheng Jinzhou frowned, just like many people did. He also saw that this uncle was obviously not fighting for one or two hundred taels of silver.

Old lady Cheng turned her head away in disdain, cleared her throat and said, "Here are a ruler and a compass, and one to make a regular heptagon. I will give you 20 minutes."

As she said that, the old lady pulled out a ruler and a pair of compasses from behind and threw them on the table—in the Great Xia Dynasty, these two things were also standard equipment for astrologists.

Le Shanhao Shi Cheng Bingxun stood alone in the sight of everyone.
