Lin Yun was intent on capturing a Ghost Practitioner to inquire about the situation with the Netherworld Water in the Netherworld, but given the current circumstances, it was clearly impossible for him to go back to those two spatial nodes to capture any Ghost Practitioners.
If, during their movement, they encountered one of those three Saint Lord Level Ghost Practitioners, or even more powerful ones, it would be tantamount to seeking death.
In the end, after consulting with True Martial Saint Lord, Lin Yun abandoned the idea.
As they continued on their way, True Martial Saint Lord analyzed the items from the Ghost Practitioners' spatial possessions to see if there was anything that could affect the Netherworld Water afflicting him.
Soon, Lin Yun and True Martial Saint Lord reached their destination.
