[Black technology system] [Helping the country build mechas] [Hanging alien civilizations] [Going to the stars and the sea] [Hot-blooded texts]
In the parallel world, the traverser Jiang Yan is just an ordinary high school student.
One day, the younger sister who was in elementary school begged Jiang Yan to help her with a little invention.
Because it was the teacher who encouraged her to go to the Gizmodo Contest, to gather the number of people...
So Jiang Xiaomeng didn't have any requirements, as long as it was an invention, as long as she was eligible for the competition, her goal was just to "participate in the prize."
As a result, Jiang Yan directly activated the [Future Technology System]!
Two days later, an anti-gravity toy car appeared at the competition scene!
When everyone thought it was just a model, the toy car suddenly started!
Soar into the air!
Straight into the sky!
Everyone's scalp is numb!
Common sense collapsed!
Jiang Xiaomeng, who was sitting in the toy car, trembled all over: "Brother!
I'm just asking you for a little invention. Are you going to send me to heaven with a sonic boom? ! "
