"Congratulations to the host for successfully signing in and obtaining the World-Destroying Black Lotus." "Congratulations to the host for successfully signing in and getting the treasure money." Others rely on cultivation to become saints, but Zhang Xuan's sainthood starts from signing in. This novel and its characters are purely fictitious.
