Vicious Villain, Working Online

What should I do if I accidentally travel through a book and become the second-in-command of the evil villain? Originally, Swann was an ordinary college student, but he accidentally traveled through time and became the second-in-command of the villain, "Elvis"! This second in command is no ordinary second in command! But it's the second-in-command who turns the protagonist group upside down! And! There are also a lot of villains who are obsessed with him! The big boss has full trust in him! Well, transitioning from a college student to an authoritative second-in-command doesn't seem too bad! But! Why do I still have that useless physique! Why didn't Elvis inherit any of his skills? Are you still acting like this? ! Just reopen it! Just when Swann was in despair! The system suddenly appeared! "Are you here to save me?!" Swann asked expectantly. Uh... The system can only see the... Mood above other people's heads? ! What the hell is this! I'm still getting ready to reopen! Good thing! The system indicates that it can collect other people's emotions. After collecting enough emotions, you can exchange them for Elvis' corresponding skills. This is right! Swann smiled! Next up! The fake Elvis appears! Vicious villain! Work online!
