Over the years, the Immortal Emperor has always controlled the Primordial Worm, preventing it from devouring the powerhouses of the Immortal Realm, thus its means are quite limited.
The Subtle Taoist Monarch and Longevity Emperor are the strongest existences it has devoured so far.
Chen Shi observed the positions of the Subtle Taoist Monarch and Longevity Emperor, which happened to be the nodes of the formation set by the Immortal Emperor.
"Twenty years ago, if this formation were used to trap me, there might have been a chance to force me to yield."
Chen Shi shook his head. Now, times have changed, and he has become immeasurably stronger than twenty years ago; this formation can no longer trap him.
