The old man is a king in the Underworld Palace?
It's not impossible.
Back in the day, the old man had injured his foundation during the battle for the Daoist tradition. His physical body was left with hidden injuries that couldn't be healed, so his cultivation didn't advance but regressed. However, his spiritual power has been progressing all along!
According to Elder Wang, if the old man hadn't been injured, he would have been able to maintain his Daoist primordial spirit and enter the Spirit Refining Realm six or seven years ago.
After becoming the Ghost King, he learned the cultivation methods from Elder Wang, so it's highly likely that he's now above the level of the Ghost King.
However, there are so many experts in the Underworld Palace, and nobody knows if any accidents will happen.
Xu Yang pondered for a moment and said, "Elder Wang, can you take me to the Underworld Palace?"
