Additionally, while at Lingshan, I picked up two Divine Skills: the Ten-Foot Golden Body and Telepathy.
The Ten-Foot Golden Body is incredibly powerful; the most straightforward proof of its strength is that even two Saints use it.
Its advantage lies in its high upper limit—used by everyone from Arhats to Saints as a defensive skill—and it requires very few resources.
The disadvantage, however, is that it demands continuous effort. The longer you cultivate it, the stronger it becomes. If neglected, it deteriorates.
Nezha's time is exceptionally valuable, but his avatars are idle. Instead of pondering esoteric paths, it's more effective to work hard on this skill to increase combat strength.
After all, no matter how abundant his resources are, they still aren't enough to sustain twelve of his avatars cultivating other skills simultaneously.
