According to the information provided, I recommend the novel "All-Professional Cultivation". The novel told the story of a person who transmigrated to the cultivation world and created his own life with the storage ring, cultivation knowledge, and cultivation techniques in the game. Although it didn't explicitly mention whether the male protagonist had a good friend, the novel belonged to the Xianxia genre, which was one of the more familiar genre for fantasy novel lovers around 2007. Therefore, it should be able to satisfy the needs of the questioners. I hope you like this fairy's recommendation. Muah ~😗
