Ibro sensed the urgency in the system's harsh tone, so he didn't delay and gave a drop of blood using his sword. The drop was controlled by the system as it said:
'Be ready to be transferred outside of here, your seal function is about to collapse.'
Ibro then didn't have the chance to witness what was going to happen with his drop of blood, as he was pushed immediately by the system to outside. Once he opened his eyes again, he found himself standing in the same place where he was surrounded by the bodies of dead system holders.
He looked at all of them as he felt a waste of effort. All of them were system holders like him, but they were unlucky to fall in the hands of the demons without having enough strength.
Ibro felt gratitude for having his necromancer cultivation way to be unlocked this early, or else he would have faced the same fate as them.
