Fu Junmo's dark eyes became even darker.

His heart trembled.

The arms hugging her were shaking a little.

He didn't expect this answer.

Looking at the palm-sized little face in front of him, Fu Junmo's eyes turned slightly red, and he kissed the tempting lips fiercely.

It seems like no one has ever treated him like this before?

These shining eyes were filled with him, making him tremble, and making him willing to do anything for her.

"Duoduo, I don't want you to be like this."

"You're fine, fine."

"I hope you will always be Qian Duoduo, the happy kid running through the peach blossom forest."

"You are the one I, Fu Junmo, chose. I will protect and love you for the rest of my life."

Loving you is not enough, how can I hate you?

The two hugged and kissed tightly.

After a long while, Qian Duoduo pushed him breathlessly, with a sweet smile flashing in his half-closed eyes, "Hey, Master Fu, do you want your image?"

"In broad daylight, in the open air, standing in the kitchen, you hugged a little girl and kissed her?"

Fu Junmo smiled amusedly and kissed the tip of her round nose. "It's all gone since I met you."

Qian Duoduo's almond-shaped eyes curved, and she pouted in anger, "What an honor, Master Fu."

Fu Junmo kissed her forehead with amusement, "It's very fumy here, let's go back to the house, the meal will be ready soon."

Qian Duoduo nodded and said with a smile, "Okay then. Thank you for your hard work, Master Fu."

Thinking about how she had told him bluntly that she couldn't cook and asked him to cook, she couldn't help but laugh out loud.

"Naughty."

Qian Duoduo happily walked out of the kitchen, skipping and humming a little song as he returned to the main house.

She saw that the door of the west room was open and Fu Yihan was sitting on the edge of the kang reading a book. She turned and went to the east room, picked up the kang table in the corner and brought it to the west room.

"Xiao Yihan, I'll give you a table to do your homework and read."

There is also a desk in her room, which is used by Fu Yihan for work.

"Thanks."

Qian Duoduo put the table at the end of the kang and glanced at the book in his hand.

The page I opened was actually Mathematical Olympiad?

Is there mathematics Olympiad in this era?

Thinking this way, I asked, "Xiaohan, are you studying Mathematical Olympiad?"

"Um."

"Who taught you that?"

"Our school principal"

"Is there a Mathematical Olympiad?"

"No."

Are you still watching without it?

Qian Duoduo stared at them for a few seconds. They were all simple and basic Olympiad math problems, which she had learned in elementary school in her previous life.

"I can do it too. I'll teach you later?"

Fu Yihan raised his eyes to look at her, the suspicion in his eyes was really devastating.

"Hey, you little brat, who are you looking down on?"

Then she pointed to the top question in the book and said, "For this question, I, your mother, don't even need to calculate. I know the answer. It's 24, right?"

Fu Yihan glanced at her and asked, "Have you seen the answer?"

Qian Duoduo covered his chest with his hands. "Oh, that's so depressing. How can you be so sharp-tongued at such a young age? Huh?"

"It's such a simple question, do I need to see the answer? I can know the answer even if I squint my eyes, right?"

Fu Yihan: This is such a big boast.

You're so old, but you haven't graduated yet, and you're bragging in front of him?

There shouldn’t be any Mathematical Olympiads in rural areas, right?

"Then tell me, how do you solve this problem?"

Qian Duoduo looked at him sideways and asked, "Do you despise your mother?"

Fu Yihan: Apart from being my mother, you don’t have any other abilities?

Qian Duoduo raised his hand and said proudly, "Paper and pen."

Fu Yihan indifferently took out a pen and paper from his schoolbag and handed it to her.

Looking at the pencil that was only slightly longer than his finger, Qian Duoduo felt a little depressed again.

When she was a child, she lived under other people's roofs and had no shortage of food, clothing, or necessities. She even bought dozens of pencils at a time, which were thrown away after being used for so long. Did this child have such a hard life?

She silently put the pen and paper on the table and began to write.

"Look and see if it's the same as what you did."

"Xiao Ming's mother bought 2 kilograms of apples and had 10 yuan left. She bought 5 kilograms and was short of 11 yuan. She asked, how much money did she bring?"

"Now, we don't know how much money Mom brought. Let's use this line segment to represent the money Xiao Ming's mom brought. If she had 10 yuan left after buying 2 kilograms, then this segment represents 10 yuan. The previous segment represents the money for buying 2 kilograms, right?"

"So, a pound of apples costs 7 yuan. I bought 2 pounds, which is 14 yuan. Add the remaining 10 yuan, and Mom took 24 yuan. Xiaohan, are you satisfied with Mom's calculation?"

Fu Yihan's heart was moved: I didn't expect that this woman could calculate so easily and her method was so simple.

Then, he pointed to the last question and said, "This one."

Qian Duoduo read out: "Adding a 3 to the end of a three-digit number increases the original number by 1236. What is the original number..."

She thought about it. Since there's no English in elementary schools nowadays, she said, "We don't know this three-digit number now, right? So, we can use the spellings b, p, and m that you've learned to use. m is for ones, p is for tens, and b is for hundreds. Add 3 after it, and we'll write 3 after it. The result is 1236 more than the original number, so we subtract bpm, which equals 1236. That's easy to calculate, right?"

“…”

Fu Yihan: Why does such a difficult question become so simple when it comes to her mouth?

Qian Duoduo has no idea how many of these basic Olympiad math problems he has solved. Although it has been many years, he can still tell the solution at a glance.

Fu Yihan's eyes were full of surprise, and he seemed to be hesitant to speak.

After talking for four pages, she smiled and said, "Okay, let's combine work and rest. Think about what I just said, and then eat. I hope to discuss this with Xiaohan in the future. Of course, if you don't understand something, you can ask me."
