Lin Fan was once the ace special forces soldier known as “Dragon Fang.” After a mission failure led to the death of a comrade, he lost heart and went into hiding under an assumed name, taking an ordinary job as a security guard in an upscale residential complex in Donghai City and preparing to drift through life. At his lowest point, he binds to the [Life Sign-In System]. By signing in at different locations, he can earn all kinds of rewards. He intends to keep a low profile, but trouble keeps finding him: coworkers who mock him, a property manager who gives him a hard time, an ex-girlfriend who looks down on him… Lin Fan has no choice but to reveal a fraction of his power again and again. Starting with the residential complex, he gradually builds a business empire and an underworld network, ultimately becoming a behind-the-scenes godfather known across the globe.
