Di Jiu held a tattered jade slip in his hands. This jade slip was only a travel note, not an array formation jade slip.
The cultivator who had left the note had recorded that he had once seen the Heavenly Fire Spirit in the Sky Screen Pit.
Di Jiu immediately recalled that he had been to the Sky Screen before. It was a dilapidated planet in the Cultivation World that had later become a mystic area. The Sky Screen Pit described in the travel note was probably not the Sky Screen that he had been to previously.
However, what had intrigued Di Jiu were not the words "Sky Screen", but "Heavenly Fire Spirit".
According to the Book of the World, the Heavenly Fire Spirit, which was formed by the condensation of the purest fire elements in the universe, could make all flames transcend nirvana and turn into immortal flames.
