"Daddy, this paper airplane is so beautiful, but I don't know how to fold it. It's so, so hard."
Lin Xiaoqian said to Lin Chen with a bit of frustration.
Lin Chen smiled and said, "Qianqian, didn't you say some paper airplanes were difficult before? But you learned them in the end, didn't you? Daddy thinks you can do it."
"If you don't know how, you can watch Daddy fold it more."
Lin Xiaoqian nodded.
"Daddy, why do you like this?"
Lin Chen was stunned.
Lin Xiaoqian actually asked such a question, and her interest in folding paper airplanes was probably starting to wane.
This wouldn't do!
Comrade Lin Xiaoqian, the country still needs you!
"Because Daddy wants to build big airplanes in the future. The airplane we have at home is made by foreigners. How about we make our own airplane in the future?"
Lin Chen stroked Lin Xiaoqian's little head.
He wasn't lying. Improving airplane manufacturing technology was the only way he could eventually build his own airplane.
"Mmm-hmm."
Lin Xiaoqian nodded, "Daddy, if we fold paper airplanes, can we build big, big airplanes in the future?"
"That's right."
Lin Chen smiled.
Lin Xiaoqian said earnestly, "Daddy, then I will study hard, and I will help you build big airplanes in the future, and we can ride in our own airplane."
Lin Chen asked in his mind, "System, I didn't lie, and Qianqian asked the question. Will this affect my ability to gain aircraft manufacturing experience?"
"Not for the time being."
Lin Chen secretly breathed a sigh of relief.
He had promised to produce a new type of drone in three months, and if it affected the improvement, he would be busy.
Even if there were no further improvements, he could still produce a new type of drone if he worked hard.
But that would be very difficult.
He would have to devote a lot of energy to it over the next two or three months.
Lin Chen continued to teach earnestly.
In the blink of an eye, it was the next day.
After practicing Tai Chi together, Xu Mengyao went out, and Lin Xiaoqian took the initiative to follow Lin Chen to learn for another hour.
"Qianqian, there will be a guest coming later. He is Daddy's classmate. Do you know what to call him?"
Lin Chen said after finishing the paper airplane folding.
"Daddy, is he a boy?"
Lin Xiaoqian asked.
Lin Chen nodded, "He is a man. If it were a female classmate, it wouldn't be appropriate for her to come to our house when Mommy isn't home."
"Then I'll call him Uncle."
"That's right."
The person coming was Zhang Yang. He had returned to China yesterday, went home to see his parents, and this morning, Zhang Yang took a plane to Shanghai to find him.
Zhang Yang had contacted him yesterday. His parents originally wanted to come too, but Lin Chen told Zhang Yang to persuade his parents not to make the trip, as it wasn't easy for them to come.
"Ding-dong—"
Before long, the doorbell rang.
Lin Chen opened the door, and Zhang Yang stood outside, carrying all sorts of gifts in large and small bags.
"Godfather, thank you for your great kindness."
"Please accept a bow from your son."
As Zhang Yang spoke, he prepared to kneel down on one knee.
Lin Chen didn't stop him. Zhang Yang glanced at Lin Chen halfway through kneeling. Lin Chen said with a smile, "Continue, Father can afford your bow."
"Hey, I'm not kneeling."
Zhang Yang nimbly stood up.
Lin Xiaoqian poked her little head out from behind Lin Chen, and she asked in confusion, "Daddy, does 'godfather' mean 'daddy'? Then is he my older brother?"
Zhang Yang: "…"
Lin Chen picked up Lin Xiaoqian and said with a smile, "He is the classmate Daddy told you about. You should call him Uncle."
"Uncle."
Lin Xiaoqian said obediently.
Zhang Yang entered the room and put down his things.
"Xiaoqian, you are so cute. Can Uncle give you a hug?"
Lin Xiaoqian reached out her little hands.
Zhang Yang carefully hugged her and said enviously, "Brother Lin, you are amazing. You have a wife, and your child is already so big. I am still single."
"Tell me which direction to pray to so I can get such a beautiful wife and such a cute daughter?"
Lin Chen laughed, "You are now a globally famous person. Don't girls confess to you?"
Zhang Yang nodded.
"Yes, and many."
"But the ones who come close now are just looking at our good relationship, hoping to take advantage of you in the future?"
"I'm too lazy to find those who have such thoughts. I'm still young. It's not too late to enter the city walls after playing for a few years."
Lin Chen glanced at the gifts Zhang Yang brought, "Zhang Yang, you brought so many things. You're being too polite."
Zhang Yang shrugged.
"I'm telling you, this is only one-third. My parents and grandpa prepared a lot, but they gave up because I said so many things couldn't be brought on the plane."
"Let's go, let's go out to eat. My treat."
Lin Chen shook his head and said, "Let's not eat out. You play with Qianqian for a while, and I'll cook. Qianqian likes the food I make. She doesn't like eating out."
"You can cook?"
Zhang Yang said in surprise.
Lin Xiaoqian: "Daddy's food is the most delicious."
"Brother Lin, this meal should be my treat."
Zhang Yang looked at Lin Chen and said.
Lin Chen smiled and said, "You eat here for lunch, and I'll go out with you for some supper at night. You treat for supper."
"Okay."
Zhang Yang nodded.
Lin Chen went to the kitchen to get busy.
Zhang Yang put Lin Xiaoqian down and said, "Qianqian, what do you want to play? Uncle will play with you."
Lin Xiaoqian thought for a while, "Drawing in the afternoon. Uncle, can you explain some math problems to me? There are some problems I can't do."
"No problem."
Zhang Yang said confidently.
At least he was a college student, and the school was okay. His math scores used to be pretty good.
Lin Xiaoqian went to the small table on the balcony and sat down.
Zhang Yang sat on the small stool next to her. Lin Xiaoqian took out a math book she usually studies.
This book was for junior high school math Olympiad.
And it wasn't for the first year of junior high school, but for the second year.
Lin Xiaoqian flipped to the folded page and looked at it.
"Qianqian, can you understand this?"
Zhang Yang said in disbelief.
The math textbooks in junior high school weren't too difficult, but the math Olympiad was ten times more difficult. Most college students would be dumbfounded when they saw those problems.
"Yes."
"But there are some things I don't understand."
"Uncle, can you teach me the parts I don't understand?"
Lin Xiaoqian said in a childish voice.
Zhang Yang: "…"
He muttered to himself: Grandma, you think too highly of me. He can't do most of these problems at all.
"Is this the power of genes?"
"Old Lin is so good at math, and his daughter is so amazing too!"
Zhang Yang thought to himself.
"Qianqian, how old are you?"
Zhang Yang asked.
Lin Xiaoqian said, "I'm almost three years old. Uncle, I don't know how to do this problem. Can you explain it to me?"
Zhang Yang looked at the problem Lin Xiaoqian was pointing to.
He found that he had absolutely no idea.
Zhang Yang coughed lightly.
"Qianqian, when we encounter problems we don't understand, we must first think for ourselves. You are so smart, you can definitely figure it out."
Lin Xiaoqian nodded.
She thought carefully.
Two minutes passed, and Lin Xiaoqian's eyes lit up, "I figured it out."
Zhang Yang: "…"
He felt like he had been critically hit.
He had just secretly checked, and there was an answer online, but he had been looking at the answer for so long and still didn't understand it.
