"I'm glad Martha sent me back!" Delia didn't wait for Shen Peng to ask, so she said to herself, Shen Peng knew that Martha was Delia's friend and a fan of Shen Peng, and she had taken a photo with Shen Peng at the beginning.

"What about her?" Shen Peng suddenly remembered the last time Martha saw him, he felt like those little girls in China had seen an idol singer, which made him very embarrassed.

"She'll go back first if she has something." Delia smiled, and then showed an expression like an invitation, "By the way, have you seen what I prepared for you, how about it?" ”

"Look, those free-kick masters are really good." Shen Peng picked up the big bag in his hand and began to walk back, and Delia immediately followed.

"I found these videos after a long time on the Internet, and it took me a week!"

"So long!"

"But it's not like I'm looking for it twenty-four hours a day, but I'll look for it when I have time, and it actually took a total of ten or so hours, hehe!"

"Thank you."

"What kind of thanks do we have to say between us, you have also helped me a lot, and I promised to teach you, naturally I must arouse your interest first, otherwise physics will be very boring."

"You mean, you know how those curveballs, the fallen balls, and even the S-shaped shot at the end of the video you do?"

"By the way, you forgot what I studied in school?"

Shen Peng then remembered that Delia was learning theoretical physics-related things in school, and she had been interested in these since she was a child, otherwise she would not like to watch science fiction movies.

"What about this...... Isn't it cumbersome to learn? ”

"It depends on your understanding! Speaking of which, did you remember Newton's three laws that you remembered last time? ”

Because Shen Peng had a lot of games some time ago, and the schedule was relatively dense, he didn't have much time to come here, so Delia asked him to remember Newton's three laws first, and then slowly talk about it.

"I remember it, but I don't understand it." Shen Peng thought about it, he had learned these things in high school, but it was all a year or two ago, and the school was not very good at that time, so he had almost forgotten it, and now it was equivalent to re-learning.

"What's not to understand?"

"For example, the first law states that any object, when not affected by an external force or a balanced force, always remains at rest or in a state of uniform linear motion until an external force acting on it forces it to change this state. Doesn't force keep an object in motion? ”

"This is just the appearance you see, in fact, it usually looks like the force is keeping the object moving, but in fact it is because of the existence of friction, friction will hinder the movement of the object, if you don't apply a force, the moving object will slowly stop."

Shen Peng listened and nodded as if he had understood.

Delia continued: "Similarly, you can imagine a situation where you have very little friction and if you are gliding on it, it will be very difficult to stop if you don't stop it. ”

After Delia's words, Shen Peng finally understood a little, and it was a feeling of sudden enlightenment.

"Well, I kind of understand, and this second law ......"

Next, Shen Peng began to say some of his questions, and Delia also explained to Shen Peng in words that were as easy to understand as possible.

Unconsciously, the two had returned to the restaurant, and Shen Peng had basically understood Newton's three laws.

In the restaurant, Lu Xueming saw that the two were talking and laughing, and quickly welcomed the two in.

"Rong Rong, how do you buy so many things?" Lu Xueming took the things and looked at them, good guys, Christmas cards, Christmas hats, and decorations on Christmas trees...... The whole nine yards.

"Not much, I haven't seen much, I saw a person, bought a car and went back!"

"No, I mean, you've never bought so much before, you just bought some Christmas cards last year and sent them to your classmates." Lu Xueming was a little puzzled, because of his influence, Delia had a relatively simple personality and didn't like troublesome things.

"People will grow, what I didn't like before, maybe I like it now!" Delia said casually.

"Okay, I understand that, but what are you buying this nutmeg, clove and cinnamon powder for, don't tell me you're going to make your own gingerbread!" Lu Xueming took out a few packets of powdered things from the bag.

"That's right!"

"How do you have that thought?" Lu Xueming asked suspiciously, although many families here make their own gingerbread at Christmas, they rarely make these at home.

"I'm interested!" Delia said, "Moreover, I believe that Shen Peng must also be very interested in this, right, Shen Peng!" ”

"Uh...... Well. Shen Peng nodded, to be honest, he was really not interested, but looking at Delia's expectant gaze, he had to nod in response.

Shen Peng's perfunctory attitude Lu Xueming and Delia both saw it, Delia gave him a blank look, and Lu Xueming laughed, "Okay, okay, it's Christmas now, you can do whatever you want!" ”

Only then did Delia take Shen Peng to get busy, setting up decorations at home, preparing food, and handing out Christmas cards...... This kind of atmosphere gave Shen Peng a hint of the New Year's feeling.

……

After a busy day, I know that at night, I finally have time to rest.

Shen Peng's physique is a little bit like lying down and sleeping, but Delia seems to be still very energetic, I don't know why.

"Shen Peng, let's make gingerbread!" Delia said, shaking the gingerbread ingredients in her hand.

"Ah...... Spare me! Shen Peng really didn't want to move, he felt that he was running around the court for more than a dozen laps, and he was not so tired.

"Hey! You also heard my dad say, originally our family didn't make gingerbread, and I did it specifically to let you know, don't let me live up to my kindness! ”

"I'm coming, I'm coming!" Shen Peng knew that he couldn't talk about Delia, so he had to get up from the sofa and come to Delia's side, "Say, how to do it?" ”

"First, pre......heat the oven first," said Delia, her hands already moving, and she had already begun to grease the baking sheet.

Shen Peng also began to help under her instructions.

"Shen Peng, do you know the legend of gingerbread?" Delia asked, as her hand moved.

Of course, Shen Peng didn't know anything about the legend of gingerbread, and shook his head, "I haven't even heard of gingerbread before, let alone any legends." ”

"Well, once upon a time, there was a square called Magler Square...... "Delia began to recount......
