Chapter 604-door

"The Wuding River is a mysterious place that flows under the plum Valley. The members of my Mei family have to cultivate the appraisal art in the Wuding River from a young age in order to obtain the divine ability and possess the appraisal talent. The entrance to the Wuding River is a door. It's unknown how long it has existed, or when it has been standing there."

"Every time a baby girl is born in our Valley, she must open the door and enter the Wuding River to cultivate and absorb the power of the river water when she's five years old. Those with high talent needed three to four years to achieve it, while those with low talent needed more than ten years to achieve small success. Perhaps it's because they've cultivated this cultivation technique, but the women of my Mei family have been married to outsiders for generations, giving birth to only girls."
