"Auntie, they've been watching us." Xu Dongbei whispered a small report to his aunt.

The twins, who are almost two years old, are now not only able to walk on their own, but also speak more and more clearly, and their sentences are whole sentences.

Xu Pingyuan also tugged at the corner of his aunt's clothes, stretched out his little finger and said to the place where the guards were standing behind:

"They're talking about us."

Because it's not a bad word, Xu Pingyuan's little girl's mood is quite stable, but she thinks it's not good to talk about other people's words behind her back.

"A-Niang said that you can't talk about others behind your back." Xu Pingyuan's appearance looks serious.

Xu Yue looked back and saw that those guards were no longer in their original positions, and they had already left.

Shaking his head at the twins, "They're just curious, so don't let the two of you hold on to them." ”

"Let's go, your aunt should have come back, I should return you to her." Xu Yue held the twins and joked as she walked.

When the twins heard this, Qi Qi frowned, and his small body sank to the ground, "Don't, I don't want to go home yet!" ”

Seeing that the brother and sister were going to sit on the ground, Xu Yue simply let go of her hand.

"Knock knock" twice, Xu Dongbei and Xu Pingyuan, who didn't want to go home and tried to threaten their aunt with the trick of 'rolling all over the ground', successfully sat on the ground with a buttock.

Obviously, I didn't expect my aunt to do this, and both of them were stunned.

Then they glanced at each other, simply patted their buttocks and got up, flattered to take Xu Yue's hand, and looked up and smiled at her.

"To go home or not to go home?" Xu Yue asked.

The two little ones nodded like pounding garlic, back!

There is nothing more interesting than their brother and sister~

Xu Yue took the little hands of the brother and sister again and walked home slowly.

Daddy and Auntie have already come from Juyong County, and the lights in the house are on, orange and yellow, which makes people's hearts warm.

Xu Dongbei and Xu Pingyuan rushed forward, smashed open the hidden gate together, rushed in like a cannonball, and ran with a small blushing face.

Xu Dongbei shouted: "Mother-in-law! ”

Xu Pingyuan shouted: "Grandpa! ”

Xu Da, who was full of food and lying on the kang and was sleeping lightly, frowned, and before he opened his eyes, he felt a cold wind rushing up, and subconsciously opened his hand, unexpectedly holding a soft little ball of meat.

"Is Grandpa sleeping? We came back today and saw a lot of outsiders! Xu Pingyuan couldn't wait to share with his grandfather the people and things he had just seen on the street.

Wang Pingping put down the design drawings in her hand, and glanced at Xu Da first, a good grandfather, the twins had to call him grandpa, it was really enough.

Xu Da noticed Wang Pingping's gaze, and rubbed his granddaughter's little face disapprenously, how can a grandfather have a grandfather!

"Grandma, there are a lot of outsiders coming to the city~" Xu Dongbei climbed onto the kang and saw the design drawings in front of Wang Pingping, his eyes lit up, he climbed in front of the drawings and tilted his head to look.

I don't know, I thought he could understand the design at a young age. In fact, I was just attracted by the large round ball on the picture.

Xu Yue swept around the other rooms and asked suspiciously, "Haven't my sister and brother come back yet?" ”

Wang Pingping told Xu Dongbei not to mess with his drawings, and replied: "I will rest with your father for two days, let them go over to the top, the military camp is outside the city, and I can't come back tonight." ”

"Is Northeast sleeping with my mother-in-law or with my grandfather today?" Wang Pingping touched Xu Dongbei's little head, and her voice was gentle.

Xu Dongbei thought about it seriously, looked at Xu Yue, who walked in after closing the door, and pointed with his little hand, "With Auntie~"

"Don't!" Xu Yue ruthlessly refused, "I don't like to sleep with people." ”

Xu Dongbei is still young, and he doesn't know how to refute it, but he only knows that his aunt rejected him, and she retracted into her grandmother's arms aggrievedly, pouting unhappily.

Xu Pingyuan in Xu Da's arms was different, and retorted excitedly with wide eyes, "A-Niang and Auntie, just sleep together!" ”

Xu Yue flicked the little girl's head, "You have a lot of reasons, but it's useless, my aunt wants to sleep by herself." ”

Xu Yue's slippers were on the kang, the warm kang bed was very spacious, anyway, there was no need for outsiders, Xu Yue lay down directly, pillowed her hands behind her head, and said to her father:

"Sima Fang has entered the city, I asked Sima Yi to take him to the health center tomorrow to see Dr. Gu to see if there is something really wrong with his brain."

Xu Da and Wang Pingping glanced at each other, one smiling proudly, the other helpless.

Knowing that the other party was looking for a random reason, but still embarrassing people, Wang Pingping didn't know what to say about the father and daughter.

However, a Sima defense can't set off any storms.

Instead, it reminded her that it was time to speed up and get ready to go south.

Jizhou, she will never give it to anyone!

Wang Pingping's eyes flashed fiercely, on the map in her mind, Jizhou already belonged to the Xu family!

"He might want to see us." Xu Da guessed for sure.

Xu Yue asked, "Then who of us is going to see him?" ”

It's impossible to go all, otherwise Cao De would still think he has a big face!

The couple looked at Xu Yue together, "It's just you, you are the most suitable." ”

Xu Yue nodded, indicating that there was no problem.

Out of the corner of his eye, he caught a glimpse of the design drawings in Xu Dongbei's hand, and coaxed his nephew to hand them over to him.

The twins don't remember to eat, and the aunt just dropped a fart in front of them, and now Xu Yue forgot about it after two sentences, and the fart took the design drawings over, "Auntie, look." ”

"Thank you~" There should be a polite aunt too, Xu Yue smiled softly at Xu Dongbei, and the little guy shyly hid in his grandmother's arms.

Xu Yue picked up the drawings and saw that the drawings were almost exactly the same as the hot air balloons, and looked at A-Niang in surprise.

"Is this a hot air balloon?" Xu Yue asked.

Wang Pingping bowed, "So you know, I thought you didn't know." ”

"I'm tired of just ground-and-flesh ramming combat, and now it's time to introduce more advanced tactics," she explained. ”

"I prefer to fight in the air rather than fight on the ground, but this idea is unlikely to come to fruition, so I can get a half-finished product first."

"I also thought about it for a long time before I thought of hot air balloons, this thing is a little too old for me, but it started with human control of the wind and the sky."

"I remember that the original hot air balloons were made of coal and firewood, which were basic fuels, plus linen, and we now have better materials than linen, and according to my calculations, we can make more mature hot air balloons."

Speaking of this, Wang Pingping suddenly became passionate, spread out the design drawings, took out a charcoal pencil and explained while calculating on the drawing:

"The limit of human beings is four thousand meters, and more than four thousand meters will be hypoxic, assuming that under the premise of not using oxygen cylinders, in aerobic conditions, based on five people, to maintain a flight altitude of two to three thousand meters, we need an eight-level ball with a volume of 2,400 to 3,000 cubic meters, and we need cloth ......."
