I ask you to build tractors, but you build rockets?

Due to the death of his father, Lin Ju was forced to take over his family's tractor factory.
Facing the tractor factory in trouble, Lin Ju said:
It doesn’t matter, the system will take action!
Since I can build tractors, it must be very reasonable for me to switch to rocket production, right?
So in the ordinary tractor factory, a tall rocket was erected.
Then the whole world discovered that this tractor factory was getting more and more outrageous:
New energy vehicles, tanks, jet engines, passenger planes, fighter jets, aircraft carriers...
Everyone pointed at Lin Ju's nose and asked, "Don't you make tractors?"
Lin Ju innocently pointed at the Mars mobile base: "Crawler type, it can go down to the ground. Just tell me if it is a tractor!"
