I revealed something that most in my family knew. The Supreme Gods actually had seen my name being referred as an Archdemon, but now realized it after I told them.
"Y-You did that?" asked Aura.
"Now that I recall, you're referred as an Archdemon by the voice of the world when you Ranked Up… No way, you actually ate and absorbed the power of an Archdemon, truly?" sked Flora.
"Yes, I even made a Path Jewel out of this power, which upgraded automatically to Supreme God-Realm, and now it is overcharged with even more demonic power. With Path Jewel helps me generate a portal to the Gates of Hell and enter Hell itself. I can even enhance my own power passively by just being there, and I even got this Demon Core." I said, as I opened my chest and revealed to them a large red jewel, I even took it out and showed it to them.
"Huh? You can just take it out?" asked Aura.
