The Overlord Mode of the Nine Serenities could be sustained for up to three minutes with the assistance of Senior White Two's partial strength... The final stage of Senior Three-Eyed's World Fusion card also lasted three minutes.
A Perfect Match!
Using the 'Core World' as a transit point, Song Shuhang resonated with Song Four to enter the Overlord Mode of the Nine Serenities.
To prevent the possibility of the Nine Serenities Overlord entering the mortal realm and bringing down divine punishment, Song Shuhang, after entering the mode, used Song Four as a coordinate to open a direct spatial passage to the Nine Serenities.
Then, his physical body stepped back, standing within the spatial tunnel.
White-Robed Golden Trigram, Immortal Fairy White Bones, and Phoenix Rite Zither Master watched as Song Shuhang's aura suddenly underwent a drastic change, shifting from a righteous and kind aura to a terrifyingly evil and abyssal aura.
