In Heavenly Court, Emperor Jun and Tai Yi were working together to refine an ominous black sword. With the demon soldiers continuously feeding the sword with the souls and blood of essence of humans, the sword garnered more and more resentment and evil spirits. The sword had been refined for hundreds of years and was about to take shape.
Since the sword was created to exterminate the Wu Tribe, Emperor Jun named it the Wu-killing Sword. Once the sword was complete, it would be another weapon for the Demon Tribe to fight Ancestor of Sorcerer. It would allow them to pay a smaller price for victory. This naturally made Emperor Jun very satisfied.
Suddenly, Bai Ze, one of the Ten Great Demon Sages, came over with a grave expression. Emperor Jun wondered what made Bai Ze look so serious, so he asked, "Bai Ze, aren't you making arrangements for the massacre of the Human Tribe? Why do you look like that? Is there someone helping the humans?"
