Back at home, Ah Bao changed his shoes, left Shen Mu and carried the ice cream into the room, his mother likes to eat pink dwarfs, and he will leave this color for his mother every time.

After Aunt Qin finished her work in the kitchen, she made tea for Shen Mu, "Yan Ning is still busy, you play with Ah Bao for a while, no one in the family understands his stuff." ”

Shen Mu was very curious about what it was, he didn't know what the two of them were doing in the study, and it was not good to follow up rashly.

It didn't take long for Ah Bao to come out of the study, with a cloth pocket in his hand, which looked a little heavy, Shen Mu walked over and wanted to help, but Ah Bao was still unwilling, so he dragged himself to the center of the living room, knelt on the floor, and took out the things inside one by one.

Shen Mu saw that it was some toy parts, like tracks.

Po pouted and began to put it together, and his mother worked in the study and asked him to take the little train to the living room to play.

Shen Mu watched as Ah Bao built the track little by little. He found that Ah Bao was very patient, the track was almost one or two meters long, it was a circular track, and Ah Bao fought alone for four or five minutes, and he was not impatient at all.

"Bao, can Dad help you fight together?" Shen Mu smiled flatteringly at the little guy.

The little guy didn't react, he was still pouting his butt and fighting, Shen Mu took him as if he agreed, and the father and son worked together to fight the track.

Aunt Qin ironed the clothes dried today one by one on the butterfly brand sewing machine placed at one foot in the living room, and looked up at the warm picture here from time to time, her eyes were full of relief.

It took four or five minutes to finally put all the tracks together.

Po takes out the main event, the little train. The body of the small train looks a little strange, and the various parts look like they are reassembled, and the colors are different. I saw Ah Bao skillfully install the small train, press it towards the switch, and the small train suddenly rang twice, and drove along the track towards the front. Although the speed was very slow, it was enough to surprise Shen Mu, he couldn't imagine that such a tattered little train was still electric.

But electric toys are very expensive, and such a small train can sell for hundreds of dollars in a store.

Shen Mu asked Bao, "Did your mother buy you the little train?" ”

Ah Bao thought that Shen Mu took him to buy a dwarf, shook his head at him, and compared his fingers a few times, he usually communicates with his mother like this, but Shen Mu can't understand it.

But Shen Mu understood and shook his head, this little train was not bought by Liu Yanning, so who bought it?

This is Aunt Qin in the corner who spoke, "That's Mr. Song's birthday gift to Bao, the wheel of the car he gave before was broken, so Bao removed the motor on it and installed it in the small train, I don't know how he got it, the little train can run by itself." ”

Shen Mu couldn't hide his surprise, Ah Bao was only more than three years old, how could he have such a strong hands-on ability, and this could not only be achieved by having strong hands-on ability, but also needed to master a certain amount of physics knowledge.

"Who is Mr. Song?" Shen Mu asked.

Aunt Qin knew how Liu Yanning and Mr. Song were arranged in the courtyard, and she took the opportunity to say, "That's Yanning's good friend, Yanning..."

Before Aunt Qin's words were finished, Liu Yanning in the study called her, "Aunt Qin, the tea is gone!" ”

Aunt Qin hurriedly turned off the ironing machine and sent water to Liu Yanning.

Shen Mu squatted down, "Bao, where did you learn so many things?" ”

It's a pity that Po won't answer him, his eyes fell on the little train, the little train ran a track and stopped, Po ran over to check.

Ah Bao poured the small train for a long time, Shen Mu saw him remove the shell of the small train, revealing the wiring inside, the power device of this toy small train is very simple, almost only need a small electric motor, plus a few copper wires can be completed.

But that's not something a three-year-old can do.

"Bao, could it be that the power is out?" Seeing that Ah Bao couldn't find out the reason, Shen Mu reminded.

Ah Bao shook his head, the battery was just replaced two days ago, it was impossible to run out of power so quickly, he frowned distressedly, it is estimated that the small motor is broken, he only has this small motor, and the small train will not be able to run up after it is broken.

Po is a little frustrated, the little train is his favorite toy.

Shen Mu took over the small motor, the motor was iron, and Ah Bao couldn't fix it by himself, he couldn't pry the motor at all.

"Dad will bring it back to the unit and fix it for you, okay?"

Ah Bao's eyes became bright again, and he tilted his head to look at him, as if asking if Shen Mu was real?

Shen Mu looked at Ah Bao's cheeks, "If it can't be repaired, Dad will find you a small motor again, okay?" ”

Po nodded again and again, jumping up and down with joy.

The little train couldn't be played, so Shen Mu helped Ah Bao remove the tracks one by one, put them in a cloth bag, and helped him carry them into the study, this time Ah Bao didn't refuse him.

The door of the study was hidden, Shen Mu knocked on the door before entering, there was no sound inside, he gently pushed the door open, and saw Liu Yanning sitting at the desk by the window flipping through the book, almost with his back to him, Shen Mu didn't see what she was doing, he vaguely remembered that Liu Yanning said that she was going to work before, although he wondered what she was doing, but he didn't bother, he gently put down his things and exited the study.

With no toys to play with, Po sat on the sofa and watched TV.

Shen Mu sat on the sofa and watched together, Ah Bao watched the Central Children's Channel, and the content broadcast was "I Love Invention", the guests of this show were all children, and they showed their small inventions on the show, and now they are playing bamboo dragonflies, which are different from the bamboo dragonflies assembled with a simple two-leaf fan and a stick, the structure of this bamboo dragonfly is slightly more complicated, but it also needs to be artificially pulled by the clockwork.

Po watched it with relish.

Shen Mu somewhat understood where Bao's creativity came from.

When Shen Mu came the next day, he brought a new small motor to Bao, the previous one had been completely burned out and could not be used, the quality of the small motor used in the toy was not very good, this motor was found by the supplier of the aerospace institute, and there was no problem with it for a few years.

Seeing the new motor, Po danced happily, holding the small motor and going to the study to find his mother, babbling and gesturing. Po's baby teeth are small, white, neat, and she smiles cutely.

"Okay, Mom knows, go play with your dad."

Ah Bao jumped out, Liu Yan stared at Ah Bao's back and fell into deep thought, obviously, with Shen Mu's company, Ah Bao was more cheerful, and Shen Mu could accompany Ah Bao to do something she couldn't do, Liu Yan thought about it and walked to the living room.

Seeing the small train loaded with the new motor start again, Ah Bao jumped with joy, and Shen Mu watched Ah Bao with a loving smile on the side.

His afterglow noticed Liu Yanning and turned his gaze, and the smile on his face didn't have time to put away. He thought they were arguing until Liu Yanning, and was about to apologize, but was interrupted.

Liu Yanning moved her gaze to the wall, as if she wasn't talking to him, "Let's stay and have a meal with Ah Bao today." ”
