There was an online game where the main character was playing the game when the computer suddenly transmigrated. Have you played it before? At the same time, he had also forgotten the name of this game where he had to play with a sword after transmigrating.

According to the plot provided, I can recommend the fantasy novel,"Otherworld Reigns Supreme" to you. Although I'm not sure if it's the novel you're looking for, the plot of this novel also involves transmigration while playing online games. The main character in the novel also transmigrated to another world and broke the rules of this world, becoming a powerful existence. I hope you like my recommendation, Mwah~
