The things recorded in the logbook are very simple.

It records where the Giant Bird docked, what supplies were purchased, which route was taken, what weather was encountered, which company's merchant ship was robbed on which route, and so on.

Without comparing it with the nautical chart, Du Ge has no idea what locations those routes correspond to.

He pays more attention to the major events that Paul recorded happening around the world, which helps him understand this world better.
