Ning took the entire spaceship into his massive storage and teleported back on top of the blue turtle that was still roaming the ocean.

Since there was nothing else to do besides wait, he decided to learn more about Space stone.

"Can I use space stone on my own? Without the machines?" Ning asked.

<Yes. You can use it as long you pump some energy onto to turn the stone back into space.>

"Cool," Ning thought. "So that must be how the Space Drive works then. Right, how exactly do I use it once I get the space out of the stone?"

<You will require a skill to control it.>

<However, there are better things you can do with a space stone than use it for travel since teleport yourself and create portals.>

"Better things?" Ning got curious. 

<You can use space stones to create storage artifacts that is accessible in all worlds including ones without any unique energy.>
