Cap 568: Time to leave the land of the undead

After the body disappeared, I noticed an Aura spread throughout this room, I hadn't noticed before because this Aura was dormant and integrated with the miasma around, but now that that woman has disappeared the Aura seems to awaken in uncontrollable fury applying a great pressure on all of us. 

"..." (I) 

"(Seal with your blood...)" (Selene) 

I could feel great pressure making my body feel so heavy as if gravity had increased ×50, those around me mostly weren't able to move. 

At that moment I hear Goddess Selene's voice in my mind and information about a sealing technique pours into my already tired mind. 

I didn't have much time to think, the Aura was getting stronger and stronger and something was glowing inside the six-pointed gem, so I stopped thinking and let my body be guided by instinct with the new information that took over my mind.
