After being killed, Xu Turan was given a system and got pulled into a certain thriller romance novel. There, she became the crucial female supporting role who seeks death. However, on the first day of transmigrating, her system was urgently recalled for repair as it was aging.

As their farewell was imminent, the system was worried about its new host so it repeatedly reminded Xu Turan: [Your role is to be a supporting character who is always seeking death. You do know what that means, right?]

Xu Turan recalled her rich experience of doing just that in her previous life and she replied affirmatively with absolute confidence.

Xu Turan, who was busy arguing with the Evil God, answered without thinking, “I’m doing what you asked me to do – trying to find ways to die.]

System: […?!]
