I recommend the novel "Wuxia Plane Trading Terminal". The protagonist transmigrated to the Wuxia world and could obtain the martial arts, secret manuals, divine weapons, and so on he needed through the trading space to realize his growth in the Wuxia space. Although the main character's name isn't Lin Sha, the main character of this novel also has a similar plot of traveling through the Wuxia space. I believe you will like this novel! I hope you like this fairy's recommendation. Muah ~😗
