Bai Long who chose to do this mission didn't really care about the reason behind the person who posted this mission, or if the Cui Clan was a good clan or an evil one.
All he needed was a huge number of humans to slaughter and use them to fuel the growth of his own cultivation and the Sword of Extermination's strength.
As long as he managed to turn the Sword of Extermination completely red in colour, Bai Long was confident enough to use it to fight against anyone regardless of how strong the weapon they possessed was.
Thus, the Cui Clan could only consider itself unlucky for obtaining Bai Long's attention.
Taking Feng Wen with him because an elder was needed to check after a mission was competed and confirm whether it had actually been completed anyway, Bai Long made her control the flying disc as be lazily spent the whole time playing with her body.
