Chapter 561: Return!

Rocky and his companions struggled intensely on the land, but Orton was equally busy underground, and what he did was far more complex than anything Rocky had undertaken.

Think about what Orton did; he first had to figure out the principle of the Moving Fortress in the shortest possible time, then figure out how to get the massive structure moving. Once the Magic Stones were delivered, he had to organize workers, who knew nothing, to charge the Moving Fortress. After all that was done, he had to select a few people and teach them how to pilot the Moving Fortress.

All of this was done by Orton alone! Except for manual labor, essentially no one could help him at all. More importantly, he had to complete everything in an extremely short amount of time; otherwise, Rocky, fighting above ground, would not be able to hold on.
