It was like what Fang Xingjian had seen. The world before him was like a world with an extremely high level of technological productivity.

The entire world was situated on a piece of metal land. This piece of metal land itself was a gigantic-scale spaceship that was one-tenth the size of the Sun.

The spaceship's engine system ceaselessly supplied the entire spaceship with energy. 

The young Hogan's memories did not understand the principles behind the engine system. However, be it his parents, teachers, or friends, all of them said that this was some kind of perpetual motion machine which supplied all of the people on the land with an endless amount of energy.
