Abbot Fa Kong wanted to set the location of the final battle at Xian Tian Palace not only because he was considering the participation of the Heavenly Phoenix.
To be honest, this was probably the most suitable place for Red Dust to fight Ye Tianmo.
Chen Luoyang's Golden Parasol Tree could be moved, which meant that he could set up Emperor Xi's ancient formation in the Xian Tian Palace and work together with the Heavenly Phoenix.
Many people in the mortal world had guessed that the Heavenly Phoenix might be able to restrain Chen Luoyang's Emperor Xi Ancient Formation.
However, it could also be said that the Heavenly Phoenix and Emperor Xi's ancient formation might have combined to produce an effect of one plus one greater than two.
In this way, their chances of winning against Ye Tianmo increased.
