"Big bro! Hang in there, I'm on my way!"
Amos let out a small sigh after hearing the sincere response in the earpiece.
He had no choice, with his strength, facing off against the tenth Apostle Jeremiah alone didn't guarantee a victory, not to mention he still had to kill the Demigod-level Agabus to become the sole victor.
He must eradicate everyone possible, using the 'Ceremony of the Dead' to turn them all into higher-level undead that are even stronger.
Upon Cain's death, he would possess three 'Abyss Dark Knights', and by killing Jeremiah and his three followers, the number of higher-level undead would reach seven!
Higher-level undead not only become stronger than they were in life, they also gain a significant boost in strength when gathered in sufficient numbers.
The stronger and more numerous the higher-level undead become, the more they can to some extent reflect their power back onto the 'Catastrophe Witch'.
