I don't understand, I don't understand, Yan Yan still carried Lu Jin into the outer study, and the outer study was in the big upper room in the outer courtyard.

Because there are few masters in Mingyuan, there are not many guests who usually come and go, so Yan Yan and Lu You simply made the west room of the upper room a study, which is why Lu Ming and Yan Yu entered the study without the permission of the master last year, because the study is next to the hall, and there is no formal door, only a curtain is hung.

No, as soon as Yan Yan hugged Lu Jin and entered the gate of the courtyard, he heard a voice from the side of the study, which was Li Sui introducing a maze model on the table to the emperor.

This maze model was completed by Lu You himself, he wanted to go to Mingzhuang, but he was not sure that he would succeed, so he followed Yan Yan's advice to make a mold first.

Yan Yan wanted to hear the emperor's opinion on this mold, but the eunuch guarding the door saw her and shouted sharply, "Lord Baihui has arrived." ”

As soon as the eunuch's voice fell, the voice of the study disappeared, and soon, Li Ji and Li Sui came out, followed by Yan Zhang.

"I've heard your princess and sister-in-law praise your daughter for a long time, and I finally saw it today, come, I'll see, how does it compare with your childhood?" When Li Ji saw Yan Yan, there was obvious surprise in his eyes.

"Jin Niang, come, give a salute to this uncle, say hello." Yan Yan put Lu Jin down.

I don't know if Yan Zhang taught Lu Jin to learn the word "uncle", or if Yan Zhang's gourd to Lu Jin pleased her, so when Yan Yan shouted: "Uncle", Lu Jin hurriedly curtsied, and then raised his head and gave Li Ji a big smile, "Uncle, okay." ”

"Okay, okay, Jin Niang, your name is Jin Niang, right? At such a young age, you will have a decent salute and hello, and you are smarter than your mother when she was a child. Li Ji quickly bent down and hugged Lu Jin.

"What about me, what about me, I'm also your uncle, don't you remember me?" Li Sui asked as he jumped to the side.

Li Sui and Lu You have been to Mingyuan twice recently, so Lu Jin may really have an impression of him, seeing Li Sui teasing her, she stretched out her hand to Li Sui and called "uncle".

"Come, the sixth uncle hugs you, and the sixth uncle has brought you good things." Li Sui stretched out his hand to pick up Lu Jin, but Li Ji didn't give it to him.

Several people entered the study, and the emperor was standing in the middle of the room, holding a piston bamboo spray canister in his hand, and when he heard Li Sui's words, he glanced at him with his eyelids, "What good things did you bring?" Why have you never seen you say something to honor me? ”

"Father, your old man is rich in the world, and his sons will not borrow flowers to offer Buddha, my little thing coaxes the child to return, and it is definitely not enough to give you an old man." Li Sui said with a grin.

Li Cong glanced at him, Li Sui was not angry, and took out a brocade bag from his sleeve pocket, and then took out a white jade carved puppy from the brocade bag.

Sure enough, Lu Jin liked it at first sight, and hurriedly reached out to reach it, but he didn't forget to say "thank you" in his mouth.

"Hey, this little thing is really weird, and I still know how to say thank you." Li Cong was also surprised.

"What's the matter of thanks, come, Jinniang, to the emperor's grandfather, oh, no, it should be called grandfather, and say hello to the emperor's grandfather." Li Ji put down Lu Jin and said to the child with a smile.

Lu Jin glanced at Yan Yan and saw that Yan Yan nodded, so he curtsied to Li Cong, "Grandfather, okay." ”

"When she goes back to the emperor, she will only say one or two words, the emperor's grandfather is too long, and the child can only say two words grandfather." Yan Yan was so frightened that he hurriedly knelt down.

In fact, before this, Yan Yan had never heard the child make two words that were not stacked sounds, Zhu was not an example, Zhu teased the child for a while that day, but Lu Jin was stunned and did not open his mouth to call her "grandmother", and finally had to leave in a huff.

How do you know that this child just gave her a scare at this time, in case the emperor misunderstood that she was playing ghosts, wouldn't he cut off his own way back?

"Jin Niang, come, be good, listen to my mother, I want to call my grandfather, grandfather, grandfather, father, remember?" Yan Yan taught the children to call people word by word.

"That's it, don't embarrass the child, grandfather, grandfather, I like this child." Li Cong waved his hand, and then squatted down and hugged Lu Jin, "This kid is indeed a little similar to you when you were a child, but it seems to be a little smarter than when you were a child." ”

After speaking, Li Cong said to Lu Jin: "What did your mother teach you besides teaching you to bow?" ”

Lu Jin understood the meaning of these words, and replied with a crisp word, "Play." ”

"Play? Oh, I don't know what to do? ”

Lu Jin's eyes rolled, and he suddenly saw the piston nozzle in Li Cong's hand, and pointed to this thing, "Play." ”

"What do you mean, you're going to play these now?" Li Cong looked at Yan Yan.

He had just tried the piston cartridge in his hand, and it was very tight, and he couldn't push it at all without a certain amount of force.

"Back to the emperor, it was my grandson who made a few toys for the little girl, some of which could be disassembled and played, and some that could be assembled. However, this one in your hand was originally intended to be used as a spray cylinder, but after trying it, the child couldn't play with it, so my grandfather made another one pulled with a rope, which was lighter. ”

Yan Yan did ask Lu You to make a set of tangrams, a nine-link for Lu Jin, and a set of detachable circles that she used to measure IQ in her previous life, which was a bit similar to the nine-link ring, but not exactly the same.

As for the piston nozzle in Li Cong's hand, Yan Yan told a little lie, she knew that Lu You and they were worried about how to increase the strength of the machine, she had the heart to tell them the method of the spring, but she was afraid that she would not be able to explain it clearly, so she thought of the piston.

According to the principle of equal action and reaction force, and then using the principle of leverage, Yan Yan felt that under the current conditions, the force of the piston bounce must be greater than the mechanism they studied.

Of course, if there are springs, that's a different story.

"I also remembered that I said this, Xiao Xi also has a few things, saying that you gave him it, and I like it so much." Li Ji added on the side.

"Did the kid do it himself?" Li Cong asked.

"Back to the emperor, yes." Yan Yan replied.

Li Cong was interested when he heard it, and ordered someone to fetch it for him to see, although Yan Yan was reluctant, he couldn't refuse, so he had to order Qing Glaze to go for a run.

Then, Li Cong put Lu Jin on the kang with him, sat down himself, and motioned for Yan Yan to sit opposite him, but Yan Yan didn't dare, and only sat sideways on the edge of the kang.
