Yang Dao controlled the car to get inside the elevator. There was no malfunction at the moment. The boy said, "RALF, how are the stats look to you?"
A mechanical voice replied, "No problem this far master. Data is good."
Yang Dao nodded and the elevator had come to the floor below. Using the reverse button on the panel, the car moved back outside the elevator. Frieda asked, "What is the principle behind this car?"
"Elector magnetic induction," said Yang Dao.
Frieda asked a lot of questions like how the car could support itself up in the void. The boy patiently answered as he drove the car out. (I am not describing them here, as I do not want to be killed for revealing the top secret.)
