The earthen stove is lit, smoke is exhausted through the flue, and the heat is transferred to the drying room. The most primitive slow fire baking is used to preserve the medicinal effects of Chinese medicinal materials to the greatest extent.

Daiyu threw a handful of sycamore seed shells into the stove. The fire burst up, making her little face red.

This is my grandmother’s life wisdom:

The shells left after purchasing the shelled sycamore seeds are excellent fuel. Not only does it save the cost of firewood, but the food cooked with the shells is also more delicious than with ordinary charcoal fire.

The rice soup in the iron pot is boiling, bubbling with steam. The aroma of porridge and rice mixed with the smell of burnt sycamore seed shells makes people feel happy.

Having been in this world for some time, Daiyu increasingly enjoys having something to do when she wakes up every day, having a goal in life, and living a fulfilling and energetic life.

Sometimes she would feel as if she was in a trance, thinking that the life in the Grand View Garden was just a dream of the Red Chamber, and that she was born in Shuangxi Town, wandering around with her grandmother, leading a mundane life.

After dinner, she put on her handmade canvas backpack and held a transparent plastic umbrella. The rain hit the umbrella, creating small water droplets.

She walked towards the bluestone slabs with "thump thump" steps.

At the end of the alley, He Shuirong was standing by the car door holding a transparent umbrella.

He was wearing a beige shirt today. He was tall and stood at the end of the cobblestone road, blending into the rain.

It was an incredible thing to see He Shuirong so early in the morning.

Daiyu was a little stunned. She looked up and looked at He Shuirong with confused eyes.

"Teacher He?"

"Well, good morning."

He Shuirong greeted her and handed her a reference book.

"Here, this math reference book is for you."

"This is?"

Daiyu stretched out her hand, and a faint rose fragrance wafted from her sleeve. He Shuirong was stunned for a moment, and a raindrop fell on his palm. The cool autumn rain made his fingertips tremble.

Daiyu quickly took the reference materials, tilted her neck, picked up the umbrella ribs, and flipped through the materials casually.

"Mathematics competition question book?"

"Ah."

He Shuirong stepped forward, put away his own umbrella, and helped Daiyu hold up her umbrella, with the entire umbrella shifted towards her.

Holding an umbrella in the rain, his left sleeve was wet by the rain, and his light grey shirt instantly turned dark grey after being soaked by the rain.

Xie Yun, who was sitting in the driver's seat, was shocked when he saw this. Is it really appropriate for Mr. He to stay in the car and enjoy himself while he is outside in the rain?

He secretly opened the car window a little to feel the chill of the autumn rain.

Daiyu looked at He Shuirong with some suspicion:

"Teacher He, did you know that there is a math competition in our school?"

When she went back yesterday, she didn't remember mentioning the math competition.

He Shuirong coughed dryly:

"Well... I was thinking it's about time for you to do the competition questions."

In the car, Xie Yun secretly heard these words through the small gap in the car window, and was speechless:

That’s right. The places for the mathematics competition at Nancheng No. 6 Middle School were specially arranged by Mr. He.

Daiyu believed it, winked at He Shuirong mischievously, and said with a smile:

"Teacher He, did you come here specially to give me the information?"

She held the information in her hand, covering the lower half of her face, and tilted her head to look at him, with a mysterious beauty like a woman holding a lute and half covering her face, plus a bit of mischievous cuteness.

He Shuirong was somewhat intoxicated by what he saw. His throat was dry and he said unnaturally:

"No... I just stopped by."

Xie Yun was speechless in the car:

Mr. He, hello, it’s just a detour of more than 50 kilometers.

Daiyu was caught in the rain this morning and felt her nose itchy. She couldn't help but sneeze:

"Ah...ah bang!"

The sound was small, like the sound of a cat turning over and acting coquettishly.

He Shuirong was afraid that they would share an umbrella and she would get wet, so he hurriedly moved the umbrella towards her again, with most of his back exposed to the rain.

Xie Yun looked at his boss's action and couldn't help but feel a sense of emotion:

No matter how domineering a CEO is, he can’t escape being a fool in love.

During morning reading, the math teacher asked Liao Qiuxia to collect all the students' math papers that they had done yesterday.

The math teacher had anticipated the difficulty of this test paper, and when he was grading the test papers, he was prepared to be hit hard.

I picked up a test paper at random, and it was full of huge ugly words.

The math teacher has corrected countless test papers and has a strong sensitivity to handwriting. He can roughly guess the owner of the test paper and then estimate the score just by looking at the handwriting.

Tried and tried.

He held a red pen in his hand, the tip of the pen touched the curl, and he drew a line upwards.

Then move the pen tip to the upper left corner, and a big red cross is about to appear.

Suddenly, his pupils dilated and his eyes were filled with disbelief.

This is impossible!

He opened the paper with the student's name on it and confirmed that the three words were "Yangliushu".

The math teacher rubbed his eyes and looked at the paper again.

He didn't believe that these were the steps to solve the problem written by Willow Tree.

That kid, who has never passed math, how could he suddenly have an epiphany?

The math teacher's first reaction:

Could this be a leak?

However, even he himself only learned the original questions of this set of math problems yesterday. The confidentiality of Yunnan Province's mathematics competition has always been excellent.

Moreover, he had just obtained the standard answer.

It can be said that in order to select the list of participants for the mathematics competition, Yunnan Province kept the test questions as confidential as the college entrance examination.

The math teacher compared the answer with the standard answer and looked up the answers below. He found that Yang Liushu's approach to solving the problem was unique and completely different from the steps in the standard answer.

Mathematics is like this, many theorems can be derived from each other, for example, Theorem B can be derived from Theorem A.

The theorems used in the steps of solving the willow tree problem are different from the standard answer.

The result is the same, there is absolutely nothing wrong with solving the problem according to his theory, and it is even more convenient than the standard answer.

All of this points to one fact:

This shows that the willow tree must have solved the problem through its own brain circuits.

Oh my God! The math teacher was a little excited. He never expected that there would be a math genius in his class, and a dark horse at that.

He continued to read the papers.

Wait, that's not right—

Why did the willow tree become empty when it came to the answer to the question?

That shouldn’t be the case. He has already listed the most difficult steps to solve the problem. The answer shouldn’t be left blank. Wouldn’t it be easy to solve?

In fact, yesterday, the math teacher also tried to solve this test paper:

The angle of this question is really tricky. You may feel it is difficult, but there are some ideas. However, when you really solve it, you find that your own thinking steps cannot solve the problem.

The math teacher was marking the papers from a God's perspective, and his heart was filled with waves.

In fact, it is not easy to solve it to this extent.

He continued to look at the second question -
