Yue Xuexia accepted two more legacies aside from the Moon Goddess. Well, the legacy from the Moon Goddess was hers by right. It cannot be considered a legacy but just returning to its owner. The Legacies of two Primordial Gods is different. This is a legacy that was meant to be owned by just a single person and this power will be his or her until she gets bored of living and finds a successor that will replace him. Like what the Shura God and the Deva God is doing right now.
It was unknown what reason they planned to do after giving away their legacies to Yue Xuexia. But it is obvious that they planned to enter reincarnation together and start afresh as mortals. Legacies of two Primordials are still too much for the current Moon Goddess and thus, the Shura and Deva are sealed on their legacy.
