In a single meeting, Ketis made a bunch of excellent suggestions to Ves.
First, he should try to involve others in his secret research projects. Even if they didn't have his specialty or weren't able to contribute as much, just the fact that they were different people with different perspectives could bring in a lot of refreshing new ideas!
Second, Ketis suggested that Lufa's different glow variations could provide crucial assistance to expert pilots who were stuck in a rut or failed to overcome their bottlenecks.
In the past, people like this either needed to seek out battle or had to rely on factors outside of their control to keep moving forward.
No expert pilot could possibly enjoy a smooth ride to ace pilot. The fact that the latter were much rarer spoke much about how difficult it must be for demigods to shed even greater parts of their mortality.
