Would Pei Xuanjing sustain a loss by allowing these powerful figures to assume forms and enter the Longevity World, allowing them to comprehend the ultimate principles and laws of Taoist Skill within the Longevity World?
Pei Xuanjing wouldn't suffer a loss. To him, the ultimate principles and laws of Taoist Skill of Longevity World are merely there. It doesn't matter who comprehends them, it wouldn't result in any loss for him.
However, when these powerful figures attempt to understand Taoist Skill, they would naturally try to stimulate their own insights. This would be of great help to the Longevity World. Their Taoist Skill and cultivation insights would be integrated into the Longevity World and be absorbed by it.
Although it doesn't compare with the origin snatched from the Taixu Venerable, supplying to the Longevity World the insight of so many powerful figures together is a great supplement that will speed up the progress of the Longevity World.
