As members of the Cheng family, most people knew about Cheng Jinzhou's status as a sick man, and while they commented heavily on his self-recommendation, most of them were unfavorable.

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 for the imperial examination, the same was true for Cheng Jinzhou. Compared with two shortcomings, there is always a shorter one...

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.

The old lady didn't pay much attention to it, and she didn't prepare any topics. At this time, she said with a straight face: "When it comes to mathematics and science, my old lady is not proficient in mathematics and science. There happen to be a few star warlocks here today, so let me They ask a question, and I will ask another question. If any of you can answer it, you can go in first."

In an era when astrologers were popular, mathematics and science were a compulsory course for nobles, and the old lady's so-called "not proficient" was nothing more than modesty.

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 noticed that a group of men in black robes appeared on the west side, and he suddenly realized. Different from the three star warlocks who came as guests, the current black robes are at a much lower level. They are star warlocks funded by the Cheng family. Due to their talents and other reasons, they cannot even get a star rating. Therefore, he can only find some wealthy families to support him on the one hand, and on the other hand, obtain some financial assistance - no matter what kind of research it is, it is very expensive.

Not as good as those above, but more than below, 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 person walked forward first and said with a smile: "Then I have a question. Let's test both of you."

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 like he was watching a play: "Now there are pheasants and rabbits in the same cage. There are thirty-five rabbits in the cage. There are ninety-four legs under the head, 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 China’s civil service examination in the 21st century, corpses of those who knew how to do the questions but had no time to do so were everywhere.

However, in this era where arithmetic in nine chapters is rare, the problem of a chicken and a rabbit in the same cage still made Cheng Jinhao next to him think hard. The linear equations of one variable and two variables were relatively common in the Great Xia Dynasty, but they were not subjects that teenagers needed to learn. It is also quite difficult to encounter similar problems for the first time.

Cheng Jinzhou glanced at his nervous cousin, decided not to give face to the two father and son, and answered bluntly: "Rabbit 12, Pheasant 23."

He didn't even use a piece of scratch 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."

Mother Cheng became happy first. There was a faint smile on Cheng Jinzhou's face, and there was a slight change.

Before going to college, he was pretty good at mathematics and physics, and occasionally fantasized that he would become a new generation of Einstein, Bohr, Rutherford... But facts have proven that as the elitism of his classmates deepens, the vulgarity of individuals becomes increasingly prominent. After Cheng Jinzhou received his master's degree, he was lost among all living beings, and no good innate genes could be seen at all.

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

"Being kind and charitable." Cheng Bingxun's face was frighteningly cold. He looked at the center with a pale look. Before his son could calculate the result, he shouted loudly: "The question must have been prepared a long time ago. Who doesn't know that Cheng Jinzhou is a famous medicine jar? 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.

The philanthropic gentleman didn't care much and said directly: "Auntie, you have always been a fair character. This question cannot be counted, but he can answer it..."

A string of words showed his contempt for Cheng Jinzhou. Without time travel, this sick man's future would 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 looked like a rogue.

A group of people covered their faces with their sleeves, looking 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.

Mrs. Cheng turned her head disdainfully, cleared her throat and said, "Here are a ruler and a compass. Make a regular heptadagon. I'll give you 20 minutes."

As she spoke, the old lady took out a ruler and a compass from behind her and threw them on the table - in the Great Xia Dynasty, these two items were also standard equipment for star warlocks.

Cheng Bingxun, a kind and charitable man, stood alone in the sight of everyone.
