The entire thing went off without a significant hitch, as planned beforehand.
In the event that the exchange went south, the predetermined plan was for Emery to lure the dark elves into the forest where the Eastern Sage was located, which had been fully set up with Hexagram formation.
After the bait was bitten and Emery managed to defeat the group of dark elf magus, Fuxi then would proceed to give their agreed sign for dealing with the threat that is the dark elf grand magus.
Emery went along with the elder which ended up enabling them to trick the elderly dark elf to destroy the barrier forcibly, exhausting most if not all of his strength.
That was the exact moment when Fuxi went in, ambushing the dark elf with the best attack he had prepared. Said attack was a profound sword formation that struck the eight main meridians of the body, sealing the victim's power and rendering them helpless.
