Yang Lan once wondered if the explosion that night destroyed everything, and if the world would be different because of the absence of him, his sister would be different.

But then he thought about it carefully and found that thinking about this kind of thing was like a short circuit in his head.

But he got used to it.

Getting used to it is a terrible thing.

Yang Lan is not a person who feels sorry for herself, but often reflects on her gains and losses since she came so far.

He still remembered that his father was a researcher at the Academy of Sciences, although he was the lowest kind, but he did not forget to always show off his exploits in front of his son.

It's just that Yang Lan was still young at that time, she didn't know much, and her memory was not as good as it is now.

Since the explosion incident in her childhood, Yang Lan has always been solving all the housework, and after watching her little sister fall asleep, she sat on the balcony alone and reflected on herself.

This habit has been around for ten years.

At first, it was just to keep myself from crying because I always thought about my parents, but then I really figured out a lot of things, such as the aunt's family next door, although it was very bad, but it would be missed very much if I never saw him again.

Another example is that Xiao Lizi in Building 2 always runs behind his buttocks, but unfortunately he can't see it.

It was not a matter of being in grief all the time, so the content of the reflection later changed from the names of the people in each building in the neighborhood to what was written on the pages and lines of the maintenance books that old man Scotty showed himself.

The ambiguous word memory has carved a deep imprint in Yang Lan's head, unlike others, who are slowly swept into the trash can as time passes. Instead, it's like someone has hammered it deep into the cerebral cortex.

There are many things that he can't forget.

"Stinky boy, have you finished reading the book you read last time?"

Scotty said as he buckled his nose and buried himself in his tattered leather back chair.

"Do you mean the book "Troubleshooting and Troubleshooting Quantum Kinetic Energy Engines"?"

Yang Lan's movements did not stop, sitting on the workbench, wearing a small headlamp on his head, and carrying an electric iron in his hand.

"Is that the name? Anyway, when you're done, get it back to me, it's all the old man's baby, and it's a shame that you lost it. ”

Although it seemed that he cared a lot to listen to his words, his lazy and listless appearance seemed to show that he did not pay attention to the book at all.

Yang Lan asked with some confusion: "I've finished reading it, but I can't figure it out, I can't touch the quantum engine, and it doesn't make sense for you to show me this kind of advanced theoretical book." ”

Scotty snorted and said, "Teach you to learn more, you still have so much nonsense." ”

Yang Lan thought about it and seemed to be the same reason, it is better to learn more than not to learn at all, thinking of this, the movements in his hands sped up a little, and he seemed to be a little happy.

These two people are also strange to say, Scotty's strange temper is well-known among the neighbors around him, but he gets along quite well with Yang Lan, who is known for his good temper in the eyes of the people around him.

Scottie looked at the joyful atmosphere of the lights on the TV and said to Yang Lan: "Stinky boy, it will be the Virgin's Day in a few days, bring Xiaozi, let's go to the red tomatoes to eat something good." ”

Yang Lan asked without giving face: "The dishes of red tomatoes don't taste good at all, why do you always go there to eat?" ”

Scotty's old face turned red and roared angrily: "Stinky boy, why do you care so much? ”

Yang Lan didn't care at all and said, "It's better for me to cook for you, I'm very good at cooking." ”

"No, I'll go to the red tomato to eat, I'll call now to determine the location."

Looking at the old man Scotty who was on the phone, Yang Lan couldn't help but sigh, the stubborn old man, ten horses couldn't pull it back.

And the old man who had booked the seat afterwards took the phone and looked at Yang Lan with a wicked smile, as if he had won a battle.

Yang Lan didn't seem to want to look at his villainous face and said: "Isn't it just that the proprietress of the red tomato looks very beautiful, you are an old man, and you are not ashamed to go to other people." ”

Scotty was really not ashamed to retort at all: "Phew, the smelly boy can't spit ivory out of his mouth." ”

"I'm not wrong, no matter how lonely people are, they are only forty years old, I see that you are almost eighty, take your heart away."

Scotty didn't want to listen to this, and said with a blowing beard and glaring: "You're only eighty, old man, I'm just over sixty, and I was also a suave character when I was young." ”

Yang Lan ignored him and snorted and said, "Hmph, if I don't talk to you, I can't do any work." ”

"Little bunny, you're getting more and more lawless now, be careful I pump you......"

Before he finished speaking, the clock at nine o'clock remembered, Scottie looked at his watch, glared at Yang Lan and said, "It's nine o'clock, you pack up and prepare to go back." ”

After saying that, he walked back to the inner room and closed the wooden door heavily.

Knowing that the day's work was over, Yang Lan turned his hand and grabbed the simple robot he made on the workbench and began to adjust the joints.

"Yang Zi, Yang Zi, you are so beautiful, Yang Zi, Yang Zi, you are so beautiful."

Yang Lan has been very fond of his sister since he was a child, no, he made a robot for Yang Zi with some leftovers picked up in the studio.

Dumbfounded, the sound system is a big speaker directly removed from an old player, and it becomes a pair of big ears when installed on the robot.

"Hehe, it's almost ready, take it back to play with my sister when the time comes."

While doing it, Yang Lan found that the time was almost ten o'clock, so she quickly packed up her things, did a rough cleaning, closed the curtains, locked the store door, and walked in the direction of home.

As soon as Yang Lan left the store, Scotty closed the door of the room and pushed it open, he looked at the direction Yang Lan left just now and sighed deeply, and then walked to the workbench where Yang Lan made a suggestion robot.

Scotty grabbed the improvised robot, which was only about a meter tall, and examined it carefully.

After a while, Scotty sighed: "What a genius, just using such a simple workbench, can make such a prototype that conforms to artificial mechanics, such a young genius, if only it appeared a few years earlier, it would be good." ”

He pondered for a long time, and finally there was a determined look in his eyes, and he gently placed the simple robot in his hand on the sofa next to him, and the action was like fiddling with a priceless treasure.

Scotty opened the bottom drawer of the workbench and rummaged through the cabinets to find all the materials and tools inside.

And at the bottom of this drawer was hidden a button, and Scotty pressed it without even thinking about it.

"It seems that the successor I am looking for has finally appeared, and it has taken three years to examine your temperament and intelligence, and now I am ready."

Scottie said this to himself, and fell into deep memories.
