On the weekend, Gu Shimu did not break his promise and made time to take Tang Yexi, Tang Xiaochu and Tang Xiaoci to the suburbs.

Before the car stopped, Tang Xiaoci saw the huge hot air balloon parked on the hillside.

Before the car stopped, he wanted to get out of the car, but Tang Xiaochu caught him and said, "Safety first!"

Tang Xiaoci had no choice but to sit quietly.

When the car stopped and Gu Wanfeng came over and opened the door for them, he cheered, jumped out of the car, and ran towards the hot air balloon like a pony.

"Brother, look, the hot air balloon is so big and beautiful!" Tang Xiaoci circled around the hot air balloon, his eyes shining with joy.

Tang Xiaoci nodded: "It's indeed beautiful. Do you know the principle of hot air balloon lift-off?"

Tang Xiaoci blinked his eyes and thought for a while, "Because my father is rich, he bought a hot air balloon and asked the staff to put the hot air balloon into the sky, and the hot air balloon took off!"

Gu Shimu: "..."

Tang Yexi: "..."

Gu Shimu just couldn't help laughing, and Tang Yexi burst out laughing.

Tang Xiaochu: "...the gas inside the hot air balloon has a high temperature and is less dense than the air outside. The density of the gas inside is small, so the gravity is small. The sum of the gravity of the internal gas and the gravity of the ball skin is less than the buoyancy of the air, so it will rise.

, this is the principle of hot air balloon taking off!”

"Oh..." Tang Xiaoci blinked again and held Tang Xiaochu's hand, "Those are not important, brother, it's important that we can sit on the hot air balloon and fly to the sky!"

Tang Xiaochu: "..."

All right.

Telling this to his silly little brother, he is just playing the piano to a cow!

Gu Shimu rubbed Tang Xiaochu's little face and touched Tang Xiaoci's cheek. He felt that during the time he had found his son, he had laughed more than he had in the past twenty years combined.

Even if Tang Xiaochu, who is as serious as a little adult, and Tang Xiaoci come together, a chemical reaction will occur and they will turn into two little pistachios!

After the preparations were completed, Gu Shimu and Tang Yexi took Tang Xiaochu and Tang Xiaoci into the hot air balloon, and the hot air balloon began to slowly take off.

Tang Xiaoci was a little nervous, but more excited.

He stood next to Gu Shimu and Tang Yexi, lying on the edge of the hot air balloon and looking down, screaming and laughing happily from time to time. It was so beautiful.

Gu Shimu rubbed his little head and chuckled, "A child's happiness is so simple."

It was just a matter of flying into the sky in a hot air balloon, but his son's smile never faded away. He was laughing and jumping, bubbling with joy.

"Yes," Tang Yexi put one hand on Tang Xiaoci's back and the other on Tang Xiaochu's shoulders, saying dotingly: "Our happiness is also very simple. Seeing them happy makes us happy."

"It makes sense!" Gu Shimu looked at his two precious sons, "I have ridden in a hot air balloon before, and I thought it was just like that. At most, the first time I rode in a hot air balloon, it felt a little fresh, but I didn't feel happy.

But when I saw Xiaochu and Xiaoci sitting together, especially Xiaoci smiling so happily, I was also very happy."

Tang Yexi’s words make so much sense!

Since having a child, he has had more ways to live a happy and happy life.

If the child is happy, he will be happy; if the child is happy, he will be happy.

Maybe, this is the reason why people like to raise children?
