Lu Changsheng knew what Xian Rusheng was thinking by looking at the Immortal Cloud Formation.
"Combination of Illusory Formation and Killing Formation?"
In fact, ordinary illusion arrays had the effect of confusing and killing.
However, those were all inherent in some high-level illusion arrays.
Xian Rusheng's Immortal Cloud Array had added an Immortal-level killing array to the foundation of the illusion array!
The combination of two Immortal-level formations.
It was indeed extremely difficult for an Immortal Array Master like Xian Rusheng to fuse.
Even the Immortal Array Masters in the entire Immortal Realm probably did not have the ability to do so.
Xian Rusheng nodded in surprise. "Senior, you have good eyesight."
Xian Huaxuan was also amazed by Lu Changsheng's eyesight.
He saw through the mystery of the Immortal Cloud Formation at a glance.
