[Reincarnation+Cultivation+Goldfinger+Villain] Zhou Ping'an was reincarnated into a different world where martial arts was respected, but was found to have no talent for cultivation. I thought I would have to spend my whole life doing nothing. When he was ten years old, his half-brother was brought into the family. "Ding! The Son of Luck has been detected!" In the original trajectory, he would be killed by this younger brother. But now? Stupid Ou Dou Dou, you will always live in Ou Nisang's shadow!
