After traveling to ancient times, I relied on my husband to win

Li Chengze was not polite and directly handed over the question that he had been looking at on his desk for half an hour but still couldn't understand.

Qin Yan took a look and raised his eyebrows, "Oh, isn't this just a mixture of addition, subtraction, multiplication and division, and Sudoku as well?"

"Oh, this is easy. This problem is about addition and subtraction, and then multiplying the multiples. The answer is 342. For this Sudoku problem, all the arrangements must be in the same order. There are more answers."

Qin Yan was writing with a brush while speaking. Li Chengze was quite shocked. He really didn't expect that his brother would be able to solve these problems that gave him a headache.

Master Zhuang, who had been shaking his head, also came over and stared at Qin Yan until he finished writing. The answer was indeed correct.

He didn't believe that this uncultured boy could do advanced math.

He asked with a glare, "How do you know these things? These are the secret techniques of mathematics in our country's imperial academy."

Qin Yan stood up again and pushed away the finger that was about to pierce his nostril. "Master, this is a piece of cake. I learned it when I was a child. It's very simple. Do you want me to teach you?"

Master Zhuang: "Humph, I don't believe it. This is just one time, and you guessed it right. Wait for me to give you another question. I will only be convinced if you answer it correctly."

Qin Yan didn't argue with the old man. He was a bit stubborn and would only get angry to death if he didn't give in.

He said casually: "Okay, you go ahead, I'm listening."

Master Zhuang: "The bamboo field is ten feet high, with the last section touching the ground and the distance from the root to the ground being three feet, how high is the bamboo sea?"

Qin Yan: "Answer: The bamboo sea is 7 feet high!"

Master Zhuang: "Now there is a field with a width of 15 steps and a width of 16 steps. How much is the field?"

Qin Yan: "Answer: One acre."

Master Zhuang: "There is another field with a width of twelve steps and a width of fourteen steps. How many steps is the field?"

Qin Yan: "Answer: 168 steps. The square field method says: the width is obtained by multiplying the number of steps by the number of steps. Divide 240 steps by the mu method to get the mu. One hundred mu is one hectare."

Zhuang Taifu: "Now there is a field one li wide and one li wide. How much is the field?"

Qin Yan: "Answer: Three hectares and seventy-five acres."

Master Zhuang asked several questions in a row, and as expected, Qin Yan answered them all.

Li Chengze was stunned listening to the two people's questions and answers.

Master Zhuang was so shocked that he could not express it in words. "How did you calculate this? There are no answers to these in the Nine Palaces Mathematics."

Qin Yan didn't care at all, not knowing how shocking it was to them. "These are all very simple. I'll write down how to calculate them for you, and you can take a look at it yourself."

Qin Yan picked up a brush and wrote down the whole process on a piece of paper and handed it to Master Zhuang.

Master Zhuang took it with great care, spread it carefully on the table, and began to stare at the process and calculate with his fingers.

A look of fascination.

Qin Yan then realized that he had shocked the person a little too much.

He turned to look at Li Chengze who was standing there in a daze, and pulled him towards the door.

"Okay, stop standing there. This old man will probably take a long time to calculate, and he probably won't be able to take care of you. Come on, I'll take you for a walk."

Li Chengze was pulled away by him. He turned around to look at the tutor who was busy calculating, shook his head and followed him.

Even the Master can’t understand it, so I’ll just forget it.

The two of them walked out of the palace and went to have a drink with Cheng Ziang and the others. They hadn't been together for a long time.

……

The holiday passed quickly, and Qin Yan also welcomed the first morning court session of the new year.

It looked dead again, floating to the main hall.

Today's discussion is a bit serious.

It turned out that a heavy snowstorm had occurred before the prince led his army back to the capital a few years ago, and the grassland was also covered with snow.

The herdsmen on the grasslands were unable to survive the winter and had to come to the Central Plains for help and to negotiate peace and marriage.

They wanted to exchange the cattle, sheep and war horses they brought from the grassland for enough food and salt for the grassland tribes to survive the winter.

Because of the heavy snow and weather conditions, the grassland tribes sent princes from several tribes, leading tens of thousands of cattle and sheep, to the Central Plains to marry the princess.

Because there was endless debate in the court at that time.

The civil officials advocated peace and seconded the proposal to marry the princess.

The military officer advocated war and refused to send the princess to the barbarian land, so he would fight her if she refused to obey.

The envoys will arrive in a month, and they will host a banquet to entertain them regardless of whether they advocate war or peace.

The key lies in how to entertain them so as to show the national power of Dongwu Kingdom and make them feel intimidated, but not to appear to look down on them.

After the emperor said this, the left prime minister stepped forward to ask for instructions, "We can send Qin County Man for this matter. Qin County Man has been outside the territory and knows a lot of things. He must also know something about those people in the frontier grasslands. Leave it to Qin County Man, and Qin County Man will definitely not let us down."

Everyone looked at Qin Yan. They naturally knew about the recent commotion in the Qin County man's family in the capital, but they were indeed some new and strange things.

The Minister of the Ministry of Revenue also stepped forward to agree, "I second the proposal. The several times that Qin County Man made moves shocked everyone. This matter will definitely be a piece of cake for Qin County Man, and it will enhance the prestige of our country."

The Minister of the Ministry of Revenue lowered his head and secretly hated him, "Qin Yan, you kid don't want the face you're given, so don't blame me for killing you."

It turned out that the Minister of the Ministry of Revenue had once looked for Qin Yan and arrogantly hinted that he could marry his concubine's daughter to him, but Qin Yan would obey his arrangements in everything and try to cling to other powerful families.

The result, of course, was that he was kicked out by Qin Yan, who secretly cursed him as a lunatic.

The Minister of the Ministry of Revenue was holding a grudge, and he had received a hint from the Left Prime Minister and followed his arrangements.

Basically everyone on the left prime minister's side came out to agree, and the emperor was indeed very optimistic about this kid Qin Yan.

His father was very happy these days. He could hear his father's laughter in the Xuan Zheng Hall.

He also went to see. His father was really relaxed now and had someone to play with. He was jealous.

Alas, there is no way, he can only continue to be this miserable emperor. He hopes that Qin Yan can give him a surprise.

"Qin boy, what do you think?"

Qin Yan was dumbfounded when Zuo Xiang mentioned him. Didn’t I come here to slack off? Why was he mentioned at all?

The emperor's question could not be avoided, so he bowed and answered, "Your Majesty, it's not that I can't do it, but I am alone, I don't have many people, I don't have much money, and I don't have a place, so I can't do this job."

The emperor raised his eyebrows, but instead of refusing, he put forward a condition, "Okay, as long as you can do well this time, I will satisfy you with whatever you need."

Qin Yan quickly agreed: "Yes, I will obey your order. Your Majesty, please rest assured that I will do a great job. I will ask Your Majesty to give me some rewards when the time comes."

The emperor laughed loudly, pointed at Qin Yan and said to the ministers around him: "Look, this kid hasn't done anything yet, but he's already thinking about asking for a reward from me."

No one in the hall said a word. Everyone could see that the emperor valued Qin County Man at this moment.

Qin Yan: "Your Majesty, just tell me if it's okay."

Emperor: "Okay, I agree to your request."

After the court session, the emperor kept Qin Yan.

Qin Yan put forward his own requirements, asking for money, people, and a large place, preferably a spacious place, or inside a house.

The emperor agreed with a wave of his hand and sent a small team of imperial guards, as well as palace maids and eunuchs for his use. The money and two boxes of gold and silver were sent to his residence, and the place was the same Hall of Supreme Harmony as last time.
