Excuse me, how to play Nu Wa Shi in the game? Did you buy it at the mall or hit the boss?

There are several ways to obtain mother snail stone: 1. Dig a high-level treasure map (there is a certain chance to dig a high-level treasure map from the Tibetan map, and pirates can also get it). 2. Kill the eight-array map (that is, the eight-array map, if there is a chance to expose Nu Wa, there will be hints in the rumor). 3. Guarding mysterious businessmen (Tian Yong, Suoxian and Donghai)
