As a member of the Cheng family, most of them know Cheng Jinzhou's identity as a sick man. While commenting on his self-recommendation, most of them are not optimistic.

However, more people's concerns are that the old lady loses her face.

The prefect Cheng Yunan also had the same concern. He looked at the direction of Cheng Jinzhou gently, and coughed and said, "Mom, Cheng Bingxun is older than Jinzhou, so let him pull the green first."

Although Cheng Jinhao aims to study in the imperial examination, the same is true for Cheng Jinzhou. Compared with the two shortcuts, there is always a shorter one...

Cheng Yunan cannot lose the old lady's decency because of her intentions.

Cheng Jinzhou looked up at his cheap father, and he couldn't help but feel a little angry, and then disappeared, comforting himself: It's just for the exchange of money, and there is not much difference between the first and second.

He was about to give up, and the "good and generous" gentleman also showed a proud smile. He didn't expect that the old lady was a strong man, so he didn't go downhill. He stood up and said, "Cheng Jinhao is indeed older, but the rules of his ancestors are not calculated like this. Since Bingxun proposed it, the old lady will investigate here."

The words are polite and polite, and there is a vague meaning that this legitimate grandson is not the other legitimate grandson. The people with the saucy Longzhi couldn't raise their heads. Cheng Bingxun took the lead first, but they didn't stop it, and there was no words to refute for a moment.

It was a trivial matter. The old lady didn't care much about it and didn't prepare any questions. At this time, she said with a stern face: "If you want to talk about mathematics, I am not proficient in it. Today, there are several astrology warlocks here, so I asked them to give a question. I'll give another question. If any of you answered it, go in first."

In an era when astrology was prevalent, mathematics and physics were a compulsory course for the nobles. The so-called "not proficient" of the old lady was just a humble word.

Cheng Jinhao took a few steps forward and stood next to Cheng Jinzhou with plastic surgery. However, his father Cheng Bingxun seemed to be even more nervous than his son.

Cheng Jinzhou turned his head indifferently and immediately found another group of men in black robes on the west side. He suddenly realized. Unlike the three astrology warlocks who were guests, the current black robes are much lower in degree. They are astrology warlocks funded by the Cheng family. Due to their talent and other reasons, they cannot even make a single star assessment, let alone a possible star warlock. Therefore, they can only find some wealthy families to support their backgrounds on the one hand, and on the other hand, they obtain some financial assistance - no matter what research is, it is very costly to eat.

The comparison is not enough, and the comparison is more than the bottom. At least compared to those guys who have no potential to become genuine astrology warlocks in their entire lives, the black robes on the west side are still very lucky, at least the level of mathematics is much higher.

One of them walked closer first and smiled and said, "Then I'll have a problem, let's take the exam for two."

The astrology warrior was about thirty years old and had a beautiful beard. With the respect of the aristocratic family for the astrology warriors, he was able to stroke his beard freely and smiled like a play: "Now there are pheasants and rabbits in the same cage, with thirty-five heads on top and ninety-four feet on bottom. What are the pheasants and rabbits?"

Cheng Jinzhou almost laughed out loud.

The problem of chickens and rabbits in the same cage is a typical Chinese-style problem. It starts from the Nine Chapters of Arithmetic and goes all the way to the civil service exams in later generations. It has always been a classic problem. Its essence is not complicated. Chicken has two legs and rabbits have four legs. Knowing the number of heads and feet, and finding their own numbers is nothing more than swapping two legs and four legs. Smarter elementary school students can also complete it. If the equation is allowed, it will be simplified to a binary equation. Stupid college students can calculate it as physical work - but if you want to talk about speed, it is not a good idea.

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

However, in this era when nine chapters of arithmetic are rare, the problem of chickens and rabbits in the same cage made Cheng Jinhao, who was next to him, pondered. The one-cent and two-cent equations were still ordinary in the Daxia Dynasty, but they were not a lesson that a teenager needed to tutor. It was quite difficult to get involved in similar problems for the first time.

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

He didn't even use a piece of draft paper.

The quick answer and the accuracy of the oral calculation made the black robe on the stage look up to Cheng Jinzhou very high and said with a smile: "That's right, the correct answer."

Cheng's mother was happy first. Cheng Jinzhou had a faint smile on his face, and there were some changes.

Before going to college, his mathematics and physics were quite good. He occasionally fantasized that he would become a new generation of Einstein, Bohr, Rutherford... But facts have proved that as the eliteization of his classmates deepened, personal vulgarization became increasingly prominent. After Cheng Jinzhou won the master's title, he was even more destroyed among the countless people, and there was no innate excellent genes at all.

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

"Good and generous" Cheng Bingxun's face was so cold that he looked in the middle pale. Before his son could calculate the result, he shouted loudly: "The question is that it has been prepared long ago. Who doesn't know that Cheng Jinzhou is a famous medicine jar, and hasn't been to school a few times..."

The man in black robe suddenly shook his sleeves and glanced at Cheng Bingxun with anger. As a star sorcerer, he cherishes his feathers very much.

Mr. Leshan and Charity didn't care much and said, "Auntie, you have always been fair in character. This question cannot be counted, and he can answer even if he can..."

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

The old lady raised the tea bowl beside her hard, slammed it heavily on the table, and said in a bad tone: "Once a child's play, are you shameless?"

"I just want fairness and an explanation." Cheng Bingxun looked like a rogue.

A group of people covered their faces with their sleeves, unable to bear to read them. Cheng Jinzhou frowned, just like many people, and he also saw that this cousin was obviously not fighting for one or two hundred taels of silver.

Old Mrs. Cheng turned her head disdainfully and cleared her throat, "There are a ruler and a compass here, and make a regular heptare, and give you 20 minutes."

As he said that, the old lady pulled out a ruler from behind and threw it on the table. In the Daxia Dynasty, these two things were also standard for astrology warlocks.
