The most arrogant in history

Chapter 146 Chickens and rabbits in the same cage.

"Screw you!"

Wen Axiu smiled, covered her mouth and ran away.

After breakfast, the guard came with Shangguan Jifu.

Ye Kun had just invited Shangguan Jifu to sit down when the guard reported again: "Sir Shangguan, Sir Ye, Miss He Tiantian has come with her father and wants to see Sir Ye."

Ye Kun nodded: "Please come in."

Shangguan Jifu frowned: "Who is He Tiantian?"

"It's the little girl you bought for me. I just let her go." Ye Kun rolled his eyes:

"Fourth brother, I see that the people of Tianmen County are hungry. You have a mountain of grain in your granary. Give some to the people. Only by winning the hearts of the people can more people follow us to do great things."

Tianmen County originally had a large stock of grain, and when Changsha was attacked last time, a lot of grain and jerky were distributed, so there was no shortage of food.

The common people are suffering, and have started selling their children.

Shangguan Jifu gave him face, nodded, and ordered his personal soldiers:

"Pass on my order. Every day, five hundred catties of rice and fifty catties of dried meat are distributed within the four gates as salted meat porridge to relieve the disaster."

The personal soldiers took the order and did it.

Ye Kun gave a thumbs up: "Fourth brother is kind and righteous, and the people support him. In the future, he will surely respond to your call."

Shangguan Jifu chuckled and said, "Don't give me that crap. I came here to see your new weapon. I heard that the bombs you made are very powerful."

Ye Kun rolled his eyes: "Why are you in such a hurry? I'll let you see it."

As they were talking, He Tiantian came with his father and kowtowed at the steps.

Ye Kun stood up and personally went to the steps to help He Tiantian's father up:

"Old He, no need to be so polite. I heard you can do the math. I have a question for you."

Old He was about 40 years old, thin and spiritless. He bowed deeply with fear and trepidation, saying, "I dare not ask for your advice. Please tell me what Lord Ye wants me to do."

Ye Kun thought for a moment and asked, "Now there are chickens and rabbits in the same cage. There are thirty-five heads on top and ninety-four legs on the bottom. How many chickens and rabbits are there?"

Shangguan Jifu couldn't help but chuckle when he heard this:

"What kind of question is this? Who is so bored that they want to put rabbits and chickens in the same cage?"

Ye Kun turned back: "Don't make trouble."

On the other side, Lao He thought for a moment, his eyes sparkling with light: "Rooster twenty-three, Rabbit twelve."

"Congratulations, you answered correctly."

Ye Kun was a little surprised. He asked Lao He to sit down and said with a smile, "How did you calculate it? Can you tell me?"

Ye Kun tested Wang Xiancheng, Huang Sizhong, and Wen Axiu on this simple problem of chickens and rabbits in the same cage. They could only use the exhaustive method and conduct experiments one by one to get the answer.

It’s not easy for Lao He to give the answer in one breath.

Old He smiled awkwardly and gestured:

"For example, if you cut off the legs of all the chickens and rabbits, there would be 35 chickens and 70 legs cut off. The remaining 24 legs are all from the rabbits. Each rabbit still has two legs left, so there are 12 rabbits. Conversely, there are 23 chickens..."

clap clap clap!

Ye Kun clapped and laughed: "Great, Lao He. I have another question, can I ask you one more?"

Lao He nodded: "Please ask the question, Master Ye."

Ye Kun asked for pen, ink, ruler and compass, drew a circle and its diameter, and asked, "What is the ratio of the length of the circle to the length of the diameter? After 3.14, can you be more precise?"

This is a problem about pi. Mathematicians of the Great Ding Kingdom have already calculated it to 3.14, and most craftsmen know this number.

Ye Kun wanted to try whether Lao He could push the value of pi a little further.

Lao He looked at the picture and frowned:

"I have calculated the circle-diameter ratio before. For example, if the diameter of the circle is one zhang, the circumference is between three zhang, one chi, four inches, and one fen, or two fen."

Ye Kun was shocked.

This is already very impressive, a mathematician buried among the people!

Old He looked at Ye Kun and asked cautiously, "Master Ye, did I calculate wrong?"

"That's right." Ye Kun nodded and wrote a line of words on the wooden board:

"The circle-diameter ratio can be a little more precise. For example, if the diameter is ten feet, the circumference should be three feet, one foot, four inches, one minute, five centimeters, nine millimeters, two seconds, and seven seconds. There are more to come, but 3.1415927 is enough."

Old He was shocked and said, "It turns out that Lord Ye is an expert in mathematics. This really opened my eyes."

"The art of numbers is endless, and I only scratch the surface."

Ye Kun smiled modestly, and using the example of a diameter of ten feet, asked Lao He if he could calculate the area.

Lao He had obviously calculated it before and gave the answer right away.

Ye Kun smiled and asked again: "What is the area of ​​a sphere with a diameter of ten feet? Can you calculate it?"

Old He was confused and conceded defeat: "Master Ye, I can't calculate the area of ​​a sphere."

Ye Kun nodded: "When I'm not busy, I'll teach you how to calculate the area of ​​a sphere."

Shangguan Jifu had long lost his patience and said with a wry smile: "Master Ye, is this useful? Can it be used in war?"

Lao He lowered his head and dared not speak.

"Why not? Everything in the world is counted."

Ye Kun rolled his eyes and asked, "Suppose we are at war and encounter the enemy army coming from a distance, how do we know the approximate distance?"

Shangguan Jifu didn't even think about it: "Just look with your eyes, how else would you know?"

"You just rely on your eyes." Ye Kun shook his head.

"There is a method of measurement called thumb distance measurement, which is based on numerical knowledge. This is very useful knowledge on the battlefield, but it's a pity that you don't know it."

Shangguan Jifu was stunned, then laughed and said, "When will you teach me?"

"I don't think you can learn it. I will teach your scouts later."

Ye Kun then stood up, asked Lao He to sit down first, and took Shangguan Jifu to the back garden to test the power of the bomb.

The bodyguard brought a bomb, buried it under the rockery, lit the fuse, and ran away.

Ye Kun took Shangguan Jifu and hid behind a big tree fifty steps away.

boom!

With a loud bang, the rockery collapsed.

When Shangguan Jifu saw the power of the bomb for the first time, he shuddered with fear and exclaimed, "It's so powerful! It's louder than thunder!"

Ye Kun stepped forward and checked the power of the bomb:

"The last time I blew up the Changsha city gate, the bomb was even bigger than this one. But a bomb that's too big is not very useful right now, and it's hard to drop it on the enemy camp, so we can only use small thunder bombs and drop them with catapults."

The bodyguards brought two more small mines.

Shangguan Jifu couldn't let it go and said with a smile: "How many people can this thing kill at once?"

"If the enemy is densely packed, it won't be a problem to kill or injure two or three at a time. Although the killing power is not great, it can cause panic in the enemy and destroy their formation. As long as there are enough thunder bombs, 10,000 of our troops can defeat 100,000 of the enemy."

"Brother Dalang is right. As long as the enemy army collapses and flees, even if there are a million soldiers, they will just be waiting to be killed."

Shangguan Jifu nodded repeatedly and said, "Take these two thunder bombs with you, and let's try it with the catapult."

Ye Kun nodded: "After lunch, let's go outside the city and give it a try. Just bring your personal soldiers with you. Thunder bombs are not needed at the moment. It must be kept secret and not let too many people know."

Shangguan Jifu was very happy and went back to make arrangements.

Ye Kun asked Lao He to go home first and prepare for the whole family to move to Pingye County with him.

Then, I went to see my second sister Youde.

Youde is feeling much better now after taking Mr. Wen's secret prescription.

Ye Kun arranged for a maid to serve Youde, and he accompanied Wen Axiu to Wenqi's house for dinner.

Wen Qi was all smiles and came out to pick him up personally.

He was accompanied by a beautiful woman, the most beautiful woman in Tianmen County, Shangguan Feiyan.

Seeing Ye Kun, Shangguan Feiyan took the initiative to salute: "Your servant Feiyan greets Lord Ye."

Ye Kun returned the greeting and said with a smile:

"Miss Feiyan, you don't have to be polite. You are Master Wen's concubine, and we are all family. In the future, when you and Master Wen have a son, you have to call Ah Xiu sister."

Shangguan Feiyan blushed and dared not speak.

I guess there are a thousand horses galloping through my heart.

If it weren’t for Ye Kun, Shangguan Feiyan wouldn’t be so miserable!

This lunch was just Ye Kun's task, just to please Teacher Wen.

After dinner, they chatted for a while and then Ye Kun went outside the city to test the power and various indexes of the thunder bomb.

Shangguan Jifu had arrived long ago and had set up two catapults.

One faces the flat ground and the other faces the hillside.

Ye Kun put on his armor and faceplate, asked everyone to be fully protected, and then said: "The thunder bomb is extremely powerful. All operations must be carried out strictly according to the procedures. If there is a mistake, you will die."

Everyone was afraid.

"Don't be afraid, as long as you do it correctly, nothing will happen."

Ye Kun demonstrated it himself, asking his personal soldiers to turn the catapult, put the land mine on the bucket, and after lighting it, he shouted, "Fire!"

Woo——!

The thunder bomb was fired at a 45-degree angle and exploded when it hit the ground three hundred steps away.

boom!

There was a loud noise, and the warhorse was frightened and neighed and screamed, jumping on the spot.

Shangguan Jifu was amazed: "Brother Dalang, this thing is really powerful. Even if it can't kill anyone, it can scare the enemy!"

A soldier on one side asked: "But our horses will also be frightened, what should we do?"

Shangguan Jifu also thought of this: "That's right, will it scare our horses and make us run around in disorder, causing us to lose our composure?"
