The five-year-old Yaya is the orphan of a meritorious scientist with the "Two Bombs and One Satellite", but her family property is taken over by her unscrupulous relatives, who forces her to live in a leaky storage room and eat black steamed buns.
In order to collect a gift for her silly son, the evil uncle and aunt actually wanted to sell her to a nouveau riche for a dark marriage!
In desperation, Yaya dug out her father's relic - an old abacus engraved with the Seven Stars of the Big Dipper. On the back was written: "My child, if you are in trouble, go to these seven grandfathers. They will love you more than your father."
Yaya awakened her super brain, cracked the code left by her father overnight, dragged the half-dead human trafficker, and boarded the green train bound for the capital.
"Uncle policeman, if I report it, they will try to steal my plan. My father said this is more important than his life!"
One sentence shocked the seven national treasure-level figures who were holding a top-secret meeting!
Grandfather of Nuclear Physics: "Dare you touch the blood of my closed disciple? Start the 'Dongfeng' project team immediately. I want to see who has the stronger head!"
The second grandfather, the father of chips: "Deprive my little grandson of his nutrition? I will make his whole family completely disappear from the information age!"
Third Grandpa, the chief aerospace engineer: "You think our Yaya has no parents? The Heavy Equipment Research Institute of the Seven Powers obeyed the order and pampered her like the top secret of the country!"
When the vicious relatives looked at the armed guards at the entrance of the village and the armed helicopters hovering overhead, and were scared to death, Ya Ya was sitting in the arms of the grandpa, pointing to the rocket model on the table in a sweet voice:
"Grandpa, this is not fun, I want to press the red button!"
The seven grandfathers looked doting on their faces: "Press! We Yaya can press whatever we want! Whoever dares to stop me should first ask if the atomic bomb in my hand will answer!"
