The Troublesome Hero Among the Heroes

Winter is here, and the first stage snow comes sparsely at dawn, and it melts as soon as it hits the ground.

In the small building of the hot spring hotel, there is only the occasional sound of turning pages in the tea room, and the sound of the pen tip rubbing against the paper.

Gradually, the wind became louder and louder, and "wu wu" howled.

Charles put down his pen and walked hurriedly outside the hotel gate, looking worriedly at the mountain road leading to the city.

The snow flakes falling in the black clouds rushed across Heaven and Earth, and a thin layer had already accumulated on the ground.

Two petite silhouettes are walking cautiously on the frozen mountain road, holding a large package in front of them.

Kola and Kola didn't expect Master Yun will wait for themselves at the gate.

Before they waited for their salute, Charles patted the snowflakes on their heads and shoulders, and said helplessly, "Isn’t it okay to just put on the cotton-padded clothes and come back? You have to hold such a big ball Climbing the mountain."

The sisters were stunned for a moment, apparently forgot that there was such an operation.

You guys didn’t expect these two little girls actually didn’t have cotton clothes. It’s okay for Cora to work in the castle. There is a stove inside to keep warm. Cora at home is miserable. Stuff straws in the middle of the layers of clothes and tie them up, and a lot of the charcoal for heating was pulled out of the ashes of the castle by Kola.

So he gave them a bonus and asked them to buy winter clothes.

Charles said to them again: "Go back quickly, take a hot bath in the bathroom, and then put on cotton clothes, pants, and socks."

In the small building, the maid sister went to the servant's room and took off the snow-stained skirt, went outside the door and shook it twice, then went back and hung it by the stove.

Charles helped them put water in the bathtub in the bathroom, then went to the kitchen and asked Boss to boil a small pot and drink a warm drink before returning to the tea room to continue writing.

"Why, there is a problem with the manuscript?"

Charles, who had just sat down, noticed that Mins across the desk was looking at himself strangely.

Mins covered his mouth with the manuscript in his hand, said with a smile: "Your kindness is enough to be eligible to run for Saintess."

Charles curl one's lip, and then Give up voicing.

At the same time, Professor Erbach was also the one who gave up the complaint.

He looked at Falufa and Xia Luxia who were sitting upright at the desk, then looked at Azi behind them, and then at Aalto who brought them. Liya, after reading the letter Charles wrote to herself at the end, she felt like she was dreaming.

"In this case, then I agree." Professor Erbach said, "From tomorrow, the two will follow your father's class. I will call the monitor and them now."

"Thank you Principal!" ×2

The two little girls thanked Professor Erbach very politely.

Then it was Enrico, Agatha and Langsha who were called by the Principal's secretary and were so scared that they went down on the spot.

The three of them are all good friends of Charles. They knew Medivh’s true identity, so they were shocked by the two cute daughters who suddenly appeared.

Professor Erbach said to them: "These two little classmates are Charles' adopted daughters. This is what he said in his letter. Please take care of them in the next month."

The first thing that came to this reaction was Enrico. He grew up in dukedom in Milan. He often heard that some Young Masters of Chamber of Commerce became fathers at the age of twelve or thirteen. If it were Charles... one or two years earlier. Not surprising.

He immediately patted his chest and promised: "Don't worry, Principal, what is the relationship between Charles and me? His daughter is my niece, and I will take care of them!"

At this time, Agatha and Langsha also came back to his senses, and the task the Principal gave them was to take care of the two little students one-on-one.

They immediately agreed, and the two-seater new mini car that had just been produced by the elves appeared in their minds at the same time.

The two children finally ushered in the first class.

When Professor Babbage walked into the classroom, he found that it was noisy today. All the students were crowded in a circle, and the girls laughed cheerfully from the center.

Can you bear it?

Babbage intends to frighten them with Dragon's Might, but he suddenly heard something, and then changed to a loud cough.

The students shuaa~ returned to their seats, and the two children sat there upright.

A class is almost over. Professor Babbage is very pleased. The two children sat there very seriously. Not only did they seem to understand the content of the lecture, but they also took a lot of notes.

Starting with Professor Babbage, as long as they don’t make a noise or trouble, they don’t have much hope.

He asked kindly: "Two new students in the class, do you understand today’s lecture?"

Falufa and Xia Luxia replied in unison : "Understood."

Professor Babbage thought they were talking, so he smiled and asked: "Then who will repeat today's content on the podium?"

He only wanted to activate the boring atmosphere of math class, but didn't expect to meet expert.

Falufa stood up, walked onto the podium confidently and said to the students: "What the professor is talking about today is the multiplication of the row matrix and the column matrix... La..."

"If you want to give an example..."

Falufa picked up the chalk and bounced and wrote the formula on the blackboard:

ㅤㅤ﹇

A=StrawberryㅤㅤB=[Cakeㅤpie]

ㅤ Blueberry

ㅤㅤ﹈

AB=⎡Strawberry Cake ㅤ Strawberry Pie⎤

ㅤㅤ⎣ Blueberry Cakeㅤ Blueberry Pie⎦

ㅤ

A=[Barbecued Pork ㅤ Red Sea Bream] ㅤ

ㅤㅤ﹇

B=Ramen

ㅤ Sushi

ㅤㅤ﹈

AB=[ Barbecued pork ramen ㅤ red sea bream sushi]

It can be seen that this kid ate a lot of good things yesterday.

Professor Babbage asked her in surprise: "Did you father teach you matrix before?"

"No." Falufa shook the head, "This is what I taught myself Father only taught me mathematical modeling."

Professor Babbage looked at the little girl with horror, then looked at the group of slightly excited students in the seat, and then said to the students "What are you happy about? The smart kid is not you. If you can have half her...no...half half and half smart, I won't have such a headache for your grades. If you could have her ¾ Smart, my performance bonus has already paid off my debt."

The students laughed.

After the math class, there is a magic array principle class, and everyone noisily clustered two children into the classroom.

The surrounding students were surprised by this group of people surrounding two cute little girls, but because they are famous for making movies, many people wonder if they are going to make children's movies.

The magic array principle class started soon, and Professor Kilby was also notified that he started the class only after slightly smiled on Falufa and Xia Ruxia.

At first, he said to the students: "I communicated with Professor Babbage, and you are now learning matrix."

"You have to learn this course well, because we Later, I will learn the matrix form of the magic circuit equation in the magic array. I can't learn it now when the time comes. I have to cry."

Then a group of people wailed.

Professor Kilby has seen this situation a lot. He said without a stir: "Today we started to study the time domain analysis of the First Rank loop and the Second Rank loop in the magic array. Today I will talk about The equation of the dynamic loop and its initial conditions."

After he finished speaking, he began to write a blackboard on the blackboard, and at the same time preached: "Everyone has already known in the previous study that the magic power content, magic sense node When it works in a magic circuit, a dynamic process is required from start to stability. A magic circuit with such dynamic nodes is called a dynamic circuit."

"A magic circuit with a dynamic node is called First Rank loops, there are two called Second Rank, three or more are high-order..."

"The equations describing these loops are first, second, and high-order linear differential equations."

Professor Kilby then drew a simple magic circuit consisting of a magic power source, a magic resistance and a magic power capacity, and then asked: "It is known that the magic pressure of the magic power source is Uₛ, magic The power flow intensity is i, the magic resistance value is R, the magic power capacity of the magic power is C, and the magic pressure is u꜀. Who can write the equation of this dynamic loop?"

The moment in the classroom Becoming very quiet, it seems that no one previews relevant courses, everyone is persuaded.

Just then, a small hand was raised.

Professor Kilby said angrily: "Just ask that little student to answer this question."

Xia Luxia came to the blackboard and began to write:

Obviously from the known formula:

⎛Ri+u꜀=uₛ(t)

⎨ㅤㅤㅤㅤ➡RCdu꜀dₜ+u꜀ =uₛ(t)

⎝i=Cdu꜀dₜ

If magic flow is used as a variable:

Ri+∫idₜC=uₛ(t)

➡Rdidt+iC=duₛ(t)dt

After she finished writing, she moved towards Professor Kilby bowed and then returned to her seat.

"Oh..." Professor Kilby sighed similarly to Professor Babbage, "If you can have her 10% smart and hard work, I won't worry about my performance. Up."
