Rui waited patiently with an expression of amusement as his grandmother continued ranting on about what she would do to the Emperor of Harmony if the formidable Sage Sayfeel wasn't protecting him at all times.
It wasn't until she finally tired herself that she finally paused, turning her attention back to Rui.
"Are you leaving soon, my child?"
"Yes, grandmother," Rui replied with a respectful tone. "Human civilization needs me if it is to have any hope of surviving the Beast Incursion without its Martial Sages. Five years is certainly less extreme than an assumed timeframe of one year, but it's still too short of a time to expect human Martial Masters to take over duties that only Sages are able to fulfill for the moment. I must travel around human civilization and accelerate the process."
