Great Emperor Zhenwu saw that it was about time, and he no longer lingered but rose to take his leave.
Zhen Yuanzi saw off the emperor from Wuzhuang Temple. On the side, a child presented a jade box, which he handed over with both hands.
Great Emperor Zhenwu asked, "What is this?"
Zhen Yuanzi said with a smile, "Meeting the Great Emperor today has indeed been refreshing and pleasurable, a humble gift, unworthy of your greatness."
Seeing him say this, the Great Emperor took the box and smiled, "I don't have a gift for you in return, just a piece of a ten-thousand-year-old mysterious turtle's shell." He flipped his palm, and a black turtle shell appeared as he added, "Gifts should be reciprocated."
