In the Sky-reaching Library, the White Ball that was placed there could be used for traversing through the different floors, so, could one use that White Ball to travel to the kingdom where the fairies reside?
If that were possible, it would save a lot of trouble, eliminating the need to use a shovel to dig down layer by layer in an effort to reach the Fairy Kingdom.
Every time Yang Yu thought about rallying Bai Jin, Iyas, and the others to take up shovels and tirelessly dig deeper, he couldn't help but chuckle.
The scene of "you carrying the load, me digging the earth" was too beautiful. If by some carelessness they were to discover coal, he could very well transform into a coal mine owner, trying to persuade everyone in the Library to come and mine the coal.
