Rui had worked during the time that the Martial Master had engaged in his little star-gazing session to create a proof of concept.

"And you're sure that this can be turned into a domain technique with even greater telescoping power?" The Martial Master inquired, shocked.
"Indeed," Rui nodded.

Rui raised his eyebrows, a little flummoxed. "I don't mean to be too rude with my inquiry but, if you care so much about astronomy, then why didn't you become an astronomer? They are able to learn much more about the universe than most Martial Artists."
