I Transmigrated into a Book and Was Given a Heavy Responsibility

A doomed cannon-fodder character is forced to save the world! After transmigrating to the gates of an immortal sect, she was identified as Xu Wei, the Nascent Soul True Lord who had been missing for three hundred years and was once the pride of her sect. At the same time, she was bound to a System called [Heaven's Path Survival]. The System told her that she had a great responsibility: she was here to stop the Demon Lord from destroying the world and save all living beings. Qin Luo replied, “Heh...” The Lord of Ten Thousand Demons, who would destroy the world, was her master. The wicked and overbearing Demon Lord of the Nether Abyss was her junior brother. The Dragon-Proud, level-up-story male lead was her neighbor. And she was nothing but a bona fide cannon-fodder character.
