Big Brother! Master Has Accepted a Disciple Again!

My name is Bai Xiaonian. Lao Deng said that if I join his sect, I will become a closed disciple and lead a mountain by myself. I believed in his evil deeds and worshiped him as my teacher. After I found out that I had been cheated, I practiced in seclusion all day long. A few years later, the master brought a second son here, whom he nicknamed the disciple who locked the door. I originally didn't want to worry about the second child, but after I learned about his identity as a demon clan, I understood the master's meaning. So I began to teach the second child carefully. After finally teaching the second child, the master brought back the third child... Bai Xiaonian: Sometimes I really want to kick Lao Deng and start his own business. Many years later, the second brother knocked on the door again: Senior Brother! Master has accepted a disciple again!
