Rumble!
As Fang Xuan was comprehending, another tremendous crash sounded outside. Countless powerful auras charged in and descended into the main hall of the Immortal Abode, led by the lord of the Central Great World and Li Tianwang.
"Go."
Fang Xuan and Feng Baiyu flashed and swiftly entered a doorway.
The moment they entered, countless formations began operating. At a glance, they could see at least several dozen enormous immortal formations in motion.
These dozens of immortal formations interlocked like teeth, forming a killing formation like a gaping maw that connected to a hidden spacetime. Once it closed, it could trap any expert below the Celestial Immortal realm within.

Fang Xuan and Feng Baiyu ventured deep into the formation, yet it seemed unable to sense them. Naturally, this was the effect of the Free King Talismans.
This talisman possessed countless unimaginable mysteries. Fang Xuan could currently exert less than one ten-thousandth of its power, yet even that was already more than enough for him.
If they had used other dao artifacts, they could only have forced their way into the Taiyuan Immortal Abode. In that case, they would have had to confront the experts of the Central Great World and Heavenly King Great World, which was virtually impossible.

More than ten thousand lower-grade pill war drums surrounded three planet-sized war drums and boomed in unison, producing resonance. Their sound waves could directly shake even World King Realm experts, or even Primal Chaos Realm experts, into nothingness.
"Haha, excellent. So many low-grade pills
