After Wearing the Book, I Shoulder a Heavy Responsibility

An early-dead cannon fodder is forced to save the world! Once he traveled to the Immortal Sect, he was identified as Nascent Soul Master Xu Wei, who had been missing for three hundred years, and was once the light of the sect. At the same time, it is bound to a system called [Tiandao Survival]. The system told her that she had a heavy responsibility and was here to prevent the demon lord from destroying the world and save the world. Qin Luo said: "Haha..." The lord of all demons who destroyed the world is her master. The evil and domineering Demon Lord of the Abyss is her junior brother. The male protagonist of Long Aotian's upgrade stream is her neighbor. She is an out-and-out cannon fodder.
