Awesome chapter! So it's safe to assume Cao Cao is now on the Top 10 list (At least power wise) considering Zeus at his prime was in it? That's awesome! I Can't wait to see more! Very excited to see Cao Cao meeting Lavinia, Azazel and others canon characters! Man, i'm getting chills thinking about the scene where people like Rias, Issei and the rest meeting the (In)famous God Slayer.
I have an idea. Why don't Cao Cao try and steal Samael's dragon slaying poison. Since the poison is made from God's curses, and true Longinus holds inside it God's dying will. Then maybe Cao can make his spear absorb Samael's poison and make it evolve. Making it capable of killing devils, gods, and dragons.
