Duke had to be cautious about recording the Wizard Plane's coordinates. If there really was something suspicious behind the Coordinate Earring, he could not bear the responsibility.
After weighing his options, he decided not to record the Wizard Plane's coordinates. Instead, he planned to visit a tourism-oriented plane in the future, where recording coordinates would be more appropriate.
The many factions of the Wizard Plane controlled all sorts of planes, and quite a few had been developed into tourist destinations,
places for entertainment and leisure. Many Wizards had purchased property there and settled down.
Those planes were like Harbor City, purely for entertainment, except the entire plane was like that.
Duke planned to purchase a property on such a plane in the future. That way, before traveling to other planes, he could first pass through those places to conceal his movements.
After all, entertainment-oriented planes generally had looser oversight. They were not as strict as the major Wizard Organizations, which placed great emphasis on security.
Duke could not guarantee that frequent travel between other planes would not draw someone's attention.
He had also become increasingly aware that Black Sail was safe enough, but not necessarily secret enough.
That was also why there were not very many Formal Wizards within Black Sail. Most of them were actually carrying out missions,
living, and so on in other planes.
There was no rush to purchase property on another plane. He merely added it to his future plans.
Duke began practicing the Shadow Breathing Method Robert had provided. This Breathing Technique was a knight training method used within the Shadow Council.
He found that the Shadow Breathing Method was generally similar to ordinary Breathing Techniques, consisting of a set of movements and a specific breathing rhythm.
Those things were easy for Duke to master
