I recommend " One Strike of Life in Online Games " to you. This is a virtual online game novel. Although it was different from the plot of the novel given in the question, there was also a plot where the female protagonist's cousin forced the male protagonist into the game. The male lead was also using the ancient martial arts that had been lost in the modern world to dominate the game. At the same time, he was also laughing at the various beautiful teachers, school belles, goddess game presidents, mature sisters, lolis, and queens in the school. I hope you like my recommendation.😗
