บท 681: Following the Footsteps

Kahn stood stupefied as soon as the system informed him about something called a Divine Key after the burst of black aura from the center of his chest. 

[System, what the hell is a divine key? How come you never told me anything about it?] he queried in an aghast tone. 

[Information sealed temporarily as the host hasn't met a hidden prerequisite condition.] responded the system in a lifeless voice. 

[What's the condition? And what does a divine key do?

The keyword is 'key'. So does it open a door or a path to something?] he asked again, his voice filled with curiosity.

[Information sealed temporarily.] replied the system again as if it didn't care about Kahn's query at all. 

[What the fuck?! Why are you hiding something so crucial?! 

I touched and absorbed his core without being able to stop or control the process. It's important for me to know this vital information.
