How does Luo Shui, a geomantic textbook, find out the secret of Luo Tianyou's apprenticeship?

Who is anonymous upstairs, scribbling and attacking others every day? How can there be such a boring and immoral person in the world? This kind of rumor attack and slander against Luo Tianyou is nothing more than someone being defeated by Luo Tianyou, being expelled from his old school, or being inferior to Luo Tianyou in technology, which is why he hates Luo Tianyou so much and spends so much time writing these rumors every day! Otherwise, who would be so boring? Luo Tianyou, you are always spreading rumors and attacking others. Have you ever seen Luo Tianyou attack others by writing posts on the Internet? How ridiculous!
