Attack the Immortal Realm

Lu Chen is a 300-pound fat man who is laughed at by the whole world. Until there was an extra system in my head, my voice was cold and my temper was extremely bad. He thought it was a plug-in, but actually he didn't know that it was the remnant soul of the powerful Nascent Soul from the world of immortality in disguise. The "system" told him that the spiritual energy would be revived three years later, and only he knew in advance... Lu Chen: "Okay, okay, are you writing a novel? Only I know about it." The novel is daily-oriented, slow-burning, has a single female protagonist, and pays attention to details.
