"Current quest completed. Main quest updated. Join the Blade Duel at Chang Lin and survive until the Formless Demon is killed," the system announced once Feng Bujue and Passing Rain abolished the Bell Demon. The mission to defeat Bell Demon had been ticked off, and the above came to replace it.
Xiao Tan, Laughing Soul, and Atobe knew that Lin Chang possessed the Shapeless and Formless Law, but they had not met Lu Qingning, so they could not confirm that Lin Chang was the ultimate antagonist. They could only attempt a guess from the term 'formless demon'. Feng Bujue and Passing Rain, though, had not heard of the term Shapeless and Formless Law; they only knew Lin Chang was a powerful antagonistic NPC, so they could also only guess that Lin Chang was the Formless Demon.
Only after the five met up could they confirm the final quest's target.
