Five years later.
Bei Cheng International Kindergarten.
There was a thirty-minute break in between classes.
Lu Xinyang, the little friend, was playing quietly in the corner of the classroom with his small computer.
His little sister, Lu Xinyue, was boasting to the other kids about her big brother.
With her hair bunched up into two little buns, she looked quite proud, "My brother, he can build rockets!"
"If Lu Xinyang is such a nerd that he can build rockets, then I might as well travel to space!"
"Hmph, you don't believe it, huh?" With her hands on her hips, the little girl ran into the classroom, huffing and puffing, "Brother, make a rocket to show them!"
Lu Xinyang was studying hacking knowledge, something he had seen mommy working on a few times.
Each time, he would quietly watch from the side and silently memorized it all.
Hearing his sister clamoring for him to make a rocket, he touched his forehead in resignation.
He really didn't know how to make a rocket.
