"Then everyone wait for me for a while."

After Lin Qi finished speaking, he left the room and changed his shoes and went out.

It was already completely dark.

There is no floor light in the corridor of the tube building, and Lin Qi turned on the flashlight that comes with his mobile phone.

came to the third floor and knocked on the door of Xiaoqian's house.

"Here we are." Shen Yan's voice came from behind the door.

The door opened, and Shen Yan stood at the door, holding a pair of torn school uniform pants in her hand, with needles and threads still stuck in them, obviously sewing.

"Good evening Aunt Shen, have you finished your homework?"

Lin Qi communicated with Shen Yan on his mobile phone during dinner time before, and Lin Qi came to pick her up when Xiaoqian finished her homework.

"It's Xiaolin, she's done her homework, I don't know if it's because of you, but she's active in her homework today."

"I usually have to leave a little bit of my homework on weekends until Sunday."

"When I got home today, I started doing it non-stop, and I was still thinking about the topic in my head when I ate."

Shen Yan remembered the change in her daughter today, and smiled softly, with indescribable satisfaction in her eyes.

"Haha, that's good."

This reminded Lin Qi of himself when he was a child.

"She's taking a shower right now, and she should be coming out soon."

"Xiaoqian-Brother Lin Qi is here, hurry up and wash it-"

Shen Yan shouted in the direction of the bathroom.

"Horse-on-"

Xiao Qian's immature reply came from the bathroom.

"Let's sit down first, you don't need to change your shoes, and the house should be cleaned up."

Lin Qi did not refuse.

In fact, after coming in, Lin Qi found that Xiaoqian's house had actually been cleaned up quite cleanly.

At least it's much better than his house!

Lin Qi hurriedly found a place to sit down and did not increase Shen Yan's workload.

Lin Qi looked at the dust marks on the torn school pants in Shen Yan's hand, and asked with some curiosity:

"Is this what Xiaoqian broke today?"

"Yes, this girl was too active in physical education class today, she fell on the ground and broke her pants."

Shen Yan said helplessly.

"You didn't fall and hurt yourself, did you?"

Lin Qi is more concerned about this issue.

"It's just a little bit broken, it's not a big deal, this wild girl's commonplace."

"It's a small sacrifice, and I don't know where she went to school."

Shen Yan laughed as she spoke.

"I'll put a band-aid on her later."

"It's a small sacrifice! Today I was the first sprinter in my PE class! ”

"Ding Dong, a boy who was trained by his father every day, didn't run away from me!"

A rather proud voice came from the direction of the bathroom.

Then a small figure with wet hair ran to Lin Qi's side and grabbed Lin Qi's arm:

"Brother, I don't have a problem with words, Ding Dong's father is a policeman, and he will train him every day!"

"I beat him out, I'm not very good!"

Xiaoqian looked at Lin Qi's eyes expectantly, and her face was full of "Praise me!" ”

It seems that this girl is quite athletic, although she is thin and small.

"Awesome!"

Lin Qi replied very seriously and gave her a thumbs up.

Xiao Qian's eyes narrowed into a crescent moon shape.

"Hehe, mom, look, my brother says I'm amazing!"

Xiao Qian turned her head to look at Shen Yan again, with a smug look on her little face.

"Okay, good, Xiaoqian is the best."

Looking at Xiao Qian, who was holding Lin Qi's arm and smiling brightly, Shen Yan suddenly felt that today's small home was full of the kind of warmth that was lacking in the past.

Is this the change that Lin Qi has brought about?

The smile on her not-so-ruddy face was one more point.

She stood up and found the Band-Aid in the cupboard.

"Xiaoqian, come here, put this on it."

Only then did Lin Qi notice that there was indeed a small abrasion red mark on Xiao Qian's little knee.

There are also traces of wounds around the knee that have healed.

Sure enough, as her mother said, falling injuries are commonplace.

Xiaoqian obediently asked Shen Yan to put a band-aid.

Then she jumped up and down to Lin Qi's side:

"Brother, can we go up?"

"I have a couple of questions for you today."

"You haven't dried your hair yet!"

Shen Yan said that she was going to get a hair dryer.

Lin Qi calculated that it was almost time to go up.

"No need Aunt Shen, I also have a hair dryer at home, so it's not too late to blow it at my house."

Shen Yan thought about it for a while and agreed.

"Xiaoqian, you have to blow it yourself later, don't trouble my brother."

"No problem!"

Xiao Qian agreed.

After letting Xiaoqian bring her homework and books, Lin Qi decided to get up and leave with her.

When she walked to the door, Shen Yan rushed over from the back room and put on a coat for Xiao Qian.

"It's cool down at night, you have to bring your coat, don't catch a cold."

Shen Yan's concern was beyond words.

Xiaoqian put on this school uniform jacket.

I don't know if it's the same as last time, the sleeves of this school uniform are still very long, and while wrapping Xiaoqian's arm deeply, there is also a lot more short.

Lin Qi was very curious about this last time.

When he left the house, Lin Qi let Xiaoqian walk in front, and he took out the flashlight of his mobile phone.

Instead of shining on the floor in front of it, it was held high above and aimed at the back of the staircase overhead.

"Eh, how does the light of the phone light light up the surroundings?"

"It's like there's a light in the hallway."

Xiao Qian turned around curiously, and saw that Lin Qi just pointed the flashlight at the ceiling, and her curiosity turned into doubt.

"This is because the light from the flashlight is reflected off the back of the white staircase on the head."

"The back of the stairs is not a smooth surface, so it will be diffusely reflected, and the light of the flashlight will be diffusely reflected to various positions in the corridor, so it will make Xiaoqian feel that the surroundings are brighter."

Lin Qi explained briefly.

Of course, Xiaoqian didn't understand.

But she continued to ask with great interest:

"Brother, man... What is Reflection? ”

"Diffuse reflection is a concept in physics that refers to the phenomenon of light projected on a rough surface reflecting in all directions"

"What is physics? Is it about the same as math? ”

"Yes, it's also a science category, but physics will only be exposed to junior high school Xiaoqian."

"Now Xiaoqian's science class in school, some of it comes from physics."

Xiao Qian turned her head while climbing the stairs and kept asking Lin Qi.

In order to prevent her from falling, Lin Cheng held one of her hands with his free left hand.

"I really like science class, the teacher talks about things that are very interesting!"

"Brother, do you know all those things?"

Lin Qi smiled slightly

"Yes, indeed."

"It's amazing—can I be as good as my brother in the future?"

"Absolutely."

......

Lin Qi's live broadcast room, because Lin Qi had been gone for almost a quarter of an hour and hadn't come back, the barrage was already full of inquiries.

"Fifteen centuries have passed, and the playmate brother has not returned."

"Is this the first unmanned live broadcast room of Shark?"
