The signal is beauty

"LeiLei, you wait for my signal and if it gets too dangerous in there, you immediately take us back to Ocasia," Hecathe instructed in a serious tone that certainly had the authoritative feel to it. 

LeiLei blinked in surprise as she took a minute to understand the man and nodded her head. 

"Okay," The girl agreed and Hecathe nodded. 

"The signal is the word 'beauty'. If I say the word then without any questions asked, you take us back," Hecathe continued as he spoke. 

LeiLei once again nodded her head but frowned just a few seconds later as she questioned in confusion, "Why is it such a common word?" 

Hecathe pursed his lips into a thin line as he heard this but didn't bother giving a response to it as he felt that the girl would be able to figure it out on her own.
