Ling Zhenfei observed the person's movements, uncertain of what he should do. If this person truly entered the Immeasurable Cave, what should he do?
Ling Zhenfei felt he should stop the person; since he had already discovered this matter, he couldn't act as though he was unaware.
But Ling Zhenfei needed to carefully ponder how to act.
Ling Zhenfei knew for certain he couldn't defeat this person in a fight. However, the Wuliang Book Tower wasn't far from the Immortal Palace; if Ling Zhenfei created some noise or a spiritual energy fluctuation, he could surely attract the attention of the people on Wuliang Mountain.
But it would definitely take some time for the people from Wuliang Mountain to arrive, and during this period, Ling Zhenfei wasn't confident he could withstand the attacks.
This person was in the Pursue Heart State; Ling Zhenfei had never fought anyone in this realm and didn't know what their strength really was.
