Introduction arc
Cang Wuzi and Tiangong Sui disguise themselves as mystics and enter the imperial palace of the Emperor in the mortal world. As they approach the Emperor, the Emperor questions the mystics why they have entered his palace. Cang Wuzi tells the Emperor that he witnessed sunbeams rain blessings on the palace, a symbol that good fortune had befallen the palace, and hence they have come with gifts of treasures for the Emperor. Cang Wuzi bestows upon the Emperor two celestial treasures: a tree with fruit that can extend ones lifeline and a drum that makes all loyal with one beat. Shocked at the miracles he has just witnessed, the Emperor bows down in respect to the two mystics and apologizes for not appropriately welcoming them into his palace. For the third gift, Cang Wuzi asks the Emperor to bring it to him, to which the Emperor looks onto the mystic in confusion. Moments later, an imperial messenger runs to approach the Emperor and tells the news of consort Qin Jing's successful delivery of the fourth prince. Holding the infant, the Emperor asks Cang Wuzi if the third treasure is his newborn child. Taking the prince from the Emperor's arms, Cang Wuzi comments that the prince possesses spiritual energy and was born flawless with great potential. He elaborates that the prince was born holding the fate of both heaven and earth in his hands and hence he does not belong in the mortal world. To prevent great calamity from befalling the mortals, he has come to take the newborn away. Thus, the birth of a celestial child that will be raised in the spiritual world is the Emperor's third treasure. And so, Cang Wuzi and Tiangong Sui fly towards the sky taking the prince with them. Later somewhere in the skies, Tiangong Sui questions Cang Wuzi if he feels ashamed giving "treasures" and spewing nonsense to trick the Emperor into taking away his newborn child. Cang Wuzi replies that not everything was complete nonsense, and that the fate of the newborn is tied to their own. However, Cang Wuzi notices that the newborn's Qi is very faint, and hence he was unable to detect the child's destiny.
