The prehistoric land has experienced tens of thousands of years of drought. The riverbeds are cracked like old tortoise shells, and the vegetation has withered into charred ghosts. The "Rain Praying Ceremony" of the tribal alliance has lasted for nine days. Young and strong men stepped barefoot on the hot turtle shell altar. Wu Zhu waved a bone staff inlaid with animal teeth and recited a vague creation epic - it is said that the rivers, lakes and seas were filled in when the world first opened.
: At dusk on the ninth day, dark clouds rolled in from the "Dragon Broken Cliff" thousands of miles away, and the electric light illuminated the faint dragon-shaped shadow in the clouds. At the moment when the first drop of rain hit the altar, a baby girl cried from the tribal leader's tent, her voice as clear as a spring breaking through the ice. At this time, the mother of the baby girl (a taciturn herbalist who is actually the incarnation of the goddess of making waves) was looking out the window. A drop of suspended water condensed on her fingertips, and she softly named her "Nine Brother Girl" - outside the tent, her nine brothers were cheering with stone spears. No one knew that this would be their last time to cheer for the rain.
