Which male protagonist in a novel could use the Hundred Ghosts Parade Formation and the Nine Swords Beyond the Swords?

"I read it a few years ago. It seems to be a time-travel novel. The main character transmigrated to a Western Continent society and learned how to set up the Hundred Ghosts Nightwalker Formation. His swordsmanship was also very good. Later on, he went to school and competed with others. He used the Nine Swords Beyond the Swords to defeat others in a few moves. Later on, someone seemed to have set up a trap to attack their school. He had no choice but to set up the Hundred Ghosts Nightwalker Formation. It's this novel. I think I read it in 2005, but the Internet wasn't developed at that time. Piracy was rampant, so the name of the book was changed. I haven't finished reading this book.
