All the clan members' cultivation and understanding will be superimposed on the host. Choice 2: Don't participate in the war between the three clans, become a Gou Immortal, and be rewarded with a cave that confuses the way of heaven and a broken version of the Jade Butterfly. Kill the ancestral dragon, lead the dragon clan, and finally control the ancient world. .... The introduction is weak! Please read the text! This novel and its characters are purely fictitious.
